To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and particularly to plane-handles.

The object of this invention is to provide a detachable handle which is adjustable and which may be applied to a plane at the side thereof in any desired position, so that when the plane is used upon its side the operator may have a convenient and effective means to hold the plane and apply to it power suficient to cause it to operate efficiently and in the intended manner. Heretofore in using a plane in this manner with the edge of the knife placed vertically it has been not only extremely awkward for the operator, but very difficult to keep the plane in the proper position to get true and effective work. Frequently the thing to be planed is of such shape or is so located that it cannot be placed upright to permit the plane to be used in the ordinary way with the fixed handle upright, and it is because on occasions it is necessary to use the plane on its side that a detachable side handle is found to be a feature of great convenience and utility. Inasmuch as planes vary substantially in size, I have devised a simple and effective mechanism the purpose of which is to render the handle adjustable, so that it may be attached to planes within a wide range of sizes.

In the drawings, Figure 1 is a side elevation of a plane with the detachable handle applied thereto. Fig. 2 is a plan view thereof. Fig. 3 is a cross-section of the plane-stock and detachable handle as shown in Fig. 1. Fig. 4 is a view of the inside of the detachable handle.

A represents the stock of an iron plane. B is a handle permanently attached to the rear end thereof.

C is a front knob or handle, also usually permanently attached to the stock A.

In ordinary use the operator grasps the two handles B C.

The other details of the plane proper, such as the knife and the adjusting devices, it is unnecessary to describe in detail herein, because they constitute no part of this invention.

D is the body of a detachable handle, preferably in the form of a shell, since it provides a strong and light construction.

E is a lip on one side of the body D, the same being by preference of sufficient length to give a long flat bearing. Obviously the number of these lips E is immaterial. Two short lips spaced apart would give the same results. The lip E will for convenience of expression be termed herein the “flat” lip. F’ is a hooked lip at the opposite side of the body D, the said hook facing the flat lip E.

Ordinarily the stock A of a metal plane is provided with cheek-pieces, one on each side, and these cheek-pieces are generally shaped as shown in Fig. 1, in which they incline upwardly from each end to a high point or crown.

In attaching the haudle-body D the flat lip E is placed against the bottom of the plane-stock, and the handle is then pushed forward toward the highest part of the cheek-piece until the hooked lip F’ engages with it and may be wedged thereon, the hook F’ overstanding the upper edge of the cheek-piece and securing the handle in place on the side of the plane. The operator may then use the plane with one or both hands. In case one hand is used the palm is placed against the rear side of the body D and the fingers are placed over the top of the plane, giving a secure grip. The position of the plane will then be on its side, and the same may be pushed along the side or edge of the thing to be planed and the work done with ease and accuracy. In case the operator desires to use two hands he may grasp the solid handle B with one hand and the detachable handle D with the other, the latter taking the place of the knob-handle C. When the work is completed, the handle D may be easily removed by sliding the same backward and freeing the hook F’ from the cheek-piece of the stock.

Inasmuch as planes vary substantially in size, I have provided a simple and effective means whereby a single detachable handle may be used upon any plane within a wide range of sizes. As will be seen from the drawings, the book F’ is provided with a shank portion F2 in its preferred form, the end of which is bent or offset and through which end passes an adjusting-screw G.

D’ D’ are guide-flanges upon the body D, which are undercut to receive the shank F2, which is preferably dovetaiied, so as to be held between the flanges D’ D’. The fit of the shank F2 in said flanges D’ D’ is sufficiently free to permit said shank to slide longitudinally. Hence by turning the adjusting-screw G the shank F2 may be moved in the guide-flanges D’ D’ and the position of the hook F’ varied relatively to the flat lip E. For convenience of adjustment one end of the adjusting-screw may have a screw-driver slot, while the other end may be provided with a head G’ to prevent the screw from moving longitudinally. In the form shown inasmuch as the screw cannot move longitudinally the rotation of the screw will transmit longitudinal movement to the offset portion of the shank F2 and a corresponding movement in the lip F’, as described. While the handle D may be jammed into engagement with the cheek-piece of the plane-stock A, it may be still further tightened by turning up the screw G after it has been jammed as tightly as possible by sliding the handle forward. Another advantage of this construction resides in the fact that by shifting the hook F’ the operative position of the handle D may be varied on a plane of any given size. For example, the hook F’ may be drawn so near to the lip E that the handle D will stand well toward the rear end of the plane, or the hook F’ may be moved so far away from the lip E that the handle D will lie closely adjacent to the highest part of the cheek-piece and well forward on the side of the plane.

Obviously the construction herein shown may be modified in a variety of ways, such as will be apparent to the mechanic skilled in the art, without departing from the spirit of this invention.

What I claim is —

1. A side handle for a plane comprising, a body portion and means projecting from said body for detachably and adjustably engaging the same at the side of a plane-stock.

2. A side handle for a plane comprising, a body portion and adjustable means for frictionally and detachably engaging the same with the cheek-piece of the plane-stock.

3. A side handle for a plane comprising, a body portion D, a flat lip on one side, and an adjustable lip on the opposite side, said lips being adapted to engage with the plane-stock.

4. A side handle for a plane, comprising, a body portion, lips on opposite sides thereof, one of said lips being adjustable and one of said lips being hooked.

To all whom it may concern:

Be it known that I, LUCAS C. CLARK, a citizen of the United States, and a resident of Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements Applicable to Planes, of which the following is a description, reference being had to the accompanying draivings, wherein —

Figure 1 is a side elevation of a plane embodying my invention. Fig. 2 is a side sectional view, on an enlarged scale, of part of the plane with my invention applied thereto. Fig. 3 is a detail view on the line x x of Fig. 2 looking in the direction of the arrows. Fig. 4 is a detail view on the line y y of Fig. 2 looking in the direction of the arrows. Fig. 5 is a view of the structure shown in Fig. 3 with the parts separated. Fig. 6 is a detail view of the block shown in Fig. 4. Fig. 7 is a view of a plane in side elevation with a modified form of my invention. Fig. 8 is a sectional elevation, on an enlarged scale, of a part of the plane embodied in my invention. Fig. 9 is a detail view of a member shown in Figs. 7 and 8.

The object of the improvement is the production of a device for adjusting the cutting-blade of the plane, which has features of novelty and advantage.

Referring to the drawings, 1 denotes the plane-body; 2, the handle. 3 is what is known as the “frog,” at the blade, 4a the cap-plate, and 5 the clamp, these parts being arranged substantially as they are in an ordinary plane. 6 is the lever for controlling the lateral adjustment of the blade. All of these parts are of the ordinary construction, and no novelty is claimed for them.

On the upper end of the frog 3 is cast the lug 7, slotted, as at 8, having a cap or filling piece 9, adapted to be held in place in the slot by the screw 10. When this cap or filing piece is in place, a hole is left through the lug 7. A screw 11, adapted to fit in the hole through the lug 7, has at one end a head 12, which bears on one side of the lug, and a collar 13, which bears on the opposite side of the lug, as clearly shown in Fig. 2. This screw is held in place in the lug by the cap or filling piece 9 and a screw 10. Beyond the collar is a screw- threaded portion which passes through the block 14, which is threaded to correspond with the threads on the screw. This block 14 has at its upper end a projecting lug 15, which is adapted to enter the aperture in the cap-plate 4a and is capable of movement lengthwise along the screw 11 in a slot 16 in the frog 3. The upper surface of the head of the screw is notched, as at 17, and a lever 18 has a lug 19, adapted to fit the notches in the head of the screw, and is mounted on the pin 20 and normally held against the head of the screw by a spring 21.

It is evident that any rotary movement of the lever 18 when intermeshed with the head of the screw will turn the screw 11, and so move the block 14 along the screw in either direction, depending upon the direction of movement of the lever. Because of this connection of this block with the blade such a movement of the block as above noted will carry the blade up or down. In the constructlon shown in the drawings the block moves the cutting-blade through the medium of the cap-plate. The block might intermesh directly with the cutting-blade, but preferably it does that through the medium of the cap-plate. If considerable adjustment of the blade is necessary in order to make it cut properly, the lever 18 may be turned as far as possible in the desired direction and then lifted, so that the lug 19 is disengaged from the slot 17 in the head of the screw 11. This will permit of the lever being moved in the opposite direction without moving the screw, and the operation may be repeated as much as desired until the proper adjustment is obtained. The blade-adjusting lever may be made to move the blade in either direction, and also it may itself be moved in either direction without moving the blade. Whenever the proper adjustment of the cutting-blade is approximately secured the lever 18 may be moved to the positions shown in Figs. 1 and 2 by simply disengaging the lug 19 from the slots 17 and moving it back to that position where it lies conveniently close to the handle of the plane, so that if a slight adjustment of the blade is desired at any time it may be effected by moving the lever in the desired direction by the finger or thumb and finger without moving the hand from the handle.

It is well known that heretofore the adjustment of the blade up and down has been accomplished by a lever, one end of which engages the blade and the other end of which is bifurcated and straddles a screw, which is turned by a thumb-nut. This well-known mechanism has decided disadvantages. For instance, the size of the head of the screw must be small, because of the small space allowed for it, and the pitch of the thread of the screw is such that it is very ditiicult to turn the screw with such a small head. Again, there is enough backlash in the old construction to cause considerable difficulty in obtaining an accurate adjustment of the adjusting device and cutting-blade. By the use of the lever in my device I have what is equivalent, in the plane illustrated in the drawings, of a four-inch wheel, with which to turn my adjusting-screw. This permits me to use a screw of such a pitch that the backlash is practically nothing. Another decided advantage which my arrangement has over the well-known screw is that the blade may be adjusted vertically without removing the hand from the handle, and a slight adjustment may be obtained by simply moving the lever by the thumb or finger in the desired direction. In the ordinary adjustment, which has been referred to above, it is necessary to remove the hand entirely from the handle in order to operate the screw, such an arrangement being not nearly as advantageous as mine.

In Figs. 7, 3, and 9 I have shown a modification in which the block 14 is not threaded, the screw 11 being threaded intoa lug 22 on the frog. The operation ot the device is substantially the same as that shown in the first six figures, with the exception that here the screw moves, while in the perferred form the screw is stationary as far as lengthwise movement is concerned.

I claim as my improvement —

1. In a plane, the combination with the cutting-blade, of a frog provided on its rear face with an apertured lug, an adjusting-screw mounted in the aperture of the said lug, a transversely-arranged screw in the said lug for securing the said adjusting-screw in position, a blade-adjusting block extending to the rear of the frog and in engagement with the said screw and secured at its forward end to the said blade, and means for rotating the said screw.

2. In a plane, the combination with the cutting-blade, of a frog rigidly secured in the plane and provided in its upper portion with a longitudinally-arranged slot, a lug formed integral with the said frog, said lug having a longitudinal slot, the rear side of which is open, an apertured block arranged in the said longitudinal slot, a screw extending through the openings in the said lug and block and means for rotating the said screw.

3. In a plane, the combination with the blade, of a frog having its upper end reduced in thickness and provided with an elongated slot therein, a lug formed integral with the said frog and provided with a longitudinal aperture extending inward from the rear side of the lug, a block slidably mounted in the slot of the frog, and having its inner end secured to the blade, an adjusting-screw mounted in the said lug and being in screw-threaded engagement with the said block, a transversely-arranged screw secured in the said lug, and a cap on the said screw, substantially as and for the purpose specified.

4. In a plane, the combination with the blade, of a frog provided in its upper end with an elongated slot, a block slidably mounted in the said slot and having its inner end secured to the blade, a lug formed integral with the said frog and provided with a longitudinal slot, an adjusting-screw having its lower end in screw-threaded engagement with the said block, and its upper end arranged in the aperture of the said lug, a head formed integral with the said screw and bearing on the lower face of the said lug, a collar formed integral with the screw and bearing on the upper face of the said lug, and means for adjusting the said screw.

5. In a plane the combination of a cutting-blade, an adjusting-screw provided with a notched head, means carried by said screw and engaging the blade, whereby the rotation ofthe screw adjusts the blade longitudinally, and a lever rotatably mounted on said screw and extending radially therefrom, said lever being free to tilt thereon to engage and disengage therewith to rotate it, substantially as described.

6. In a plane, the combination of a cutting-blade, an adjusting-screw provided with a notched head, means carried by said screw and engaging the blade whereby the rotation of the screw adjusts the screw longitudinally, a lever rotatably mounted on said screw and extending radially therefrom, and being free to tilt thereon to engage and disengage therewith to rotate it, and a spring to normally hold the lever in engagement with the screw.

7. In a plane the combination of the cutting-blade, the adjusting-screw having a notched head, means actuated by the said screw for adjusting the said blade, an adjusting-lever mounted on said screw and adapted to engage or be disengaged from the notched head of the said screw, said lever being adapted and located to be operated by the hand of the operator grasping the handle of the plane, and a spring to normally hold the lever in engagement with the said screw.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to the class of planes, especially those used for forming grooves and tongues to match; and one of the principal objects thereof is to provide in a single structure means for forming a groove and means for forming a corresponding tongue, thereby accomplishing the same result as is usually attained by the use of a pair of match-planes.

In the accompanying drawings, Figure 1 is a side elevation of a duplex plane made in accordance with my present improvements. Fig. 2 is a plan view, partly in section, of the plane. Fig. 3 is a vertical cross-section taken on line x x of Fig. 2 and looking in the direction of the arrow. Fig. 4 is a perspective, taken partly in section, of the middle portion of the plane-stock; and Fig. 5 is a cross-section taken on the line y y of Fig. 2 looking in the direction of the arrow.

In the several views similar parts are designated by similar characters of reference.

The stock 1 of the plane is of extra width, so as to accomrnodate two cutting-irons 2 and 3, the former being formed for cutting a tongue upon the edge of a board and the latter being formed for cutting a groove to match said tongue. These cutting- knives are set reversely one to the other upon upwardly and rearwardly inclined beds 4 and 5, which are integral with the stock, and the latter is provided upon one side with a throat or mouth 6 for the cutting-iron 2 and upon the other side with a throat 7 for the cutting-iron 3. The stock is also formed with a sole 8 to match the tongue-cutter 2 and a sole 9 to match the groove-cutter 3, said soles being separated by a guiding-flange 10, depending from the stock. It will be observed each of the throats 6 and 7 is open at its outer side, thereby affording clearance in use and also facilitating the construction of the plane, and that each throat is formed opposite the body portion 1a of the other sole. At the front of each throat is formed an upwardly and forwardly extending integral apron 11, and these aprons are joined to a high rib 12, integral with the stock and rising therefrom between the cutting-irons 2 and 3. Said rib extends at each end beyond the throats, whereby the stock is effectually stiffened, thereby adapting the plane, although of light construction, to meet all the requirements of the art. It will be seen also that each of the inclined beds 4 and 5 is joined at its inner side to the rib 12, thereby giving an extra stiffness to the rib and stock, and, further, that each of the throats is surrounded on three sides by a continuous integral rib or box-like structure, which minimizes the liability of chattering of the plane. It will also be seen, as at Fig. 4, that the rib 12 preferably forms a substantial continuation of the pendent guiding-flange 10. The stock is provided at its ends with handles 13 and 14, arranged one reversely to the other, so that either may be used in connection with its associated cutting-iron and so that, if desired, the operator may use both hands in holding the plane, which is often a great convenience. Preferably each handle is in line longitudinally of the stock with its associated cutting-iron, as illustrated at Figs. 2, 3, and 5, although they may be otherwise arranged within the scope of my improvements. The illustrated construction affords ample clearance for the hand of the operator. The cutting-irons may be held upon their beds or sides by clamping irons or bows 15 and 16, each of which may be provided upon its inner side with an ear 17, which is attached by a screw 18 to the vertical side of the stiffening-rib 12, said ear 17 being formed between the ends of the clamping-iron, and the latter having at its upper end a clamping-screw 19, threaded into the clamping-iron and bearing against the cutting-iron, so that by driving said screw pressure is brought upon the cutting-iron both near the cutting-point thereof and also at the upper portion thereof, thereby obtaining steadiness ofthe cutting-iron in operation.

It will be observed that one of the principal features of the stock illustrated relates to the combination between that portion of the stock which carries one of the cutters with the other portion of the stock which carries the other of the cutters. It will be seen that owing to the provision of two diverse soles, with corresponding cutters, a broader and stiffer stock is formed than would be required for a single cutter. It will also be noted that since the two soles are built or formed upon a single member the central vertical rib 12, which constitutes a truss or stiffening member for the stock, constitutes such stiffening member in respect of each of the two soles or planing devices which are comprised in the complete implement. Furthermore, the same double construction and double utility obtains with respect to the guiding-flange 10, which depends from the stock.

A further important advantage obtained by the described construction pertains to the manner in which the plane-body is strengthened at the points where the mouths are located. Since these months are each open on one side, each sole, considered by itself, is correspondingly weakened; but by reversing the arrangement of the cutters not only is the single guide-plate 10 brought into proper position for use with both of the cutters, but the two mouths are also located at different points in the length of the stock, so as not to come adjacent one to the other. This organization brings a solid or uncut portion of one side of the stock adjacent to the plane-mouth that is formed in the other side of the stock, considering the stock as a whole. Thus at points 1a in Fig. 2 portions of the soles constitute lateral reinforcing-ribs which join the main vertical member or web 10 12 of the stock, and so reinforce the same and produce a very rigid construction even when the stock is made so thin as to produce a plane of relative light weight. In Figs. 3 and 5 these two portions of the stock are clearly illustrated and indicate the exceptional advantages obtained in an implement of this general class by combining a pair of planes into a single structure. It will further be perceived that the finishing of the bottom of the plane, including all of the surfaces of the soles and of the gage-plate or filange 10, may be accomplished at one milling operation. Moreover, the increased strength obtained by the invention greatly facilitates the milling operation, since the casting has great rigidity, notwithstanding the open plane-mouths. Thus the plane is inexpensive to produce, as well as having advantages for the user. By combining the two planes into one implement a much less total weight is required for the complete outfit than in the case of two separate implements usually furnished for this class of work. The advantage is obtained of additional strength due to the presence in whichever of the two planing devices may be for the moment employed of the stability and rigidity due to the reinforcement thereof by the companion part not then in direct use.

It is convenient to have a plane with two handles, since it may by this means be more reliably guided in the hands of the workman. The reversed mounting of the two handles is a convenience for this purpose.

It will be observed that the plane is duplex in that it has two cutting-irons, that the single stock is provided with two independent soles each having a cutting-iron, that the cutting-irons are independently attachable and diverse or formed for making different cuts one from the other, that said irons are mounted at different points in the stock — that is, so that their cutting points or portions do not coincide one with the other — that the guiding flange or plate 10 is between the cutting edges of the irons 2 and 3 and extends substantially the entire length of the sole to stiffen the same and is provided upon both sides with guiding-surfaces, as at 10a and 10b, that the rib 12 is disposed between the cutting-irons 2 and 3, forms a substantial continuation of the guiding-flange 10, is integral with the stock 1, and extends at each end beyond the months or throats 6 and 7, and that the aprons 11 form angular continuations of said rib.

Variations may be resorted to within the scope of my invention, and portions of my improvements may be used without others in various kinds of planes.

To all whom it may concern:

Be it known that I, CHARLES H. FOX, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to bench-planes; and it consists, substantially, in the improvements hereinafter more particularly described.

Without attempting to enumerate the advantages of the present invention by comparison with other planes hitherto devised it may be stated that the present invention has for its object to provide a plane of simple and effective construction and organization and one in which the plane mechanism is economically and compactly seated in place upon the stock in such manner as to overcome or prevent any tendency to chattering ot the operative portion of the plane-iron, and also to provide an extended bearing for the rear or under side of the supporting-frame of the plane mechanism, and to greatly strengthen the fastening for such frame without materially adding to the weight of the plane.

A further object is to provide means for preventing dislodgment or disorganization of the plane mechanism either in part or in entirety due to any tendency thereof to rise from its seat upon the stock, from drag upon the plane-iron, or from other causes.

A still further object of the invention is to provide means for fastening the supporting-frame to the stock in the most. rigid and secure manner, while readily permitting vertical or up and down adjustments of such frame for the purpose of effecting changes in the position of a wearing-sole in conformity with the needs thereof, and also to provide means whereby the up and down adjusting devices for the plane-iron are housed in part and protected against accidental displacement in the use of the plane.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, wherein —

Figure 1 is a longitudinal sectional elevation of a plane embodying my improvements, said view being taken just to one side of the median line of the width of the stock, several of the parts being shown in elevation. Fig. 2 is a top or plan view thereof with the plane mechanism removed. Fig. 3 is a central longitudinal sectional view of the top iron of the plane. Fig. 4 is an enlarged view similar to Fig. 1 to more clearly indicate the construction and organization of parts or elements comprising or constituting the plane mechanism, the stock or body of the plane being broken off at each end. Fig. 5 is also a similar view taken to one side of the median line of the width of the stock and just to the outer side of one of the fastening-screws for the frame of the plane mechanism, so as to clearly show the construction and organization. Fig. 6 is a view looking at the rear or under side of the supporting-frame for the plane mechanism, said plate being minus any of such mechanism as well as the adjusting elements for the plane-iron; and Fig. 7 is a view looking at the front or upper side of the supporting-frame, the stock and top iron being shown in vertical section and the laterally-adjusting lever for the plane-iron being partly broken off.

Before proceeding with a more detailed description it may be stated that in the practice of my invention I provide the body or stock of the plane of any suitable wood, and I form therein from top to bottom an opening the surface of the rear wall of which is inclined to provide a seat of proper angle or inclination for the plane-iron mechanism and the surface of the front wall of which is specially constructed at the bottom of the stock to cooperate with the lower end of the frame of the plane mechanism, as and for the purpose hereinafter specifically explained. To provide an extended and continuous bearing-surface for the supporting-frame of the plane mechanism, I extend the rearwardly and upwardly inclined surface of the rear wall of the opening in the stock some distance above the top of the stock, and preferably such extension is in duplicate with the parts thereof on opposite sides of the median line of the width of the stock. The supporting-frame is provided separately with some suitable laterally and vertically adjusting devices for the plane-iron, and the said plane-stock and supporting-frame are so constructed that the principal parts of the said vertically-adjusting devices are snugly and conveniently housed in such manner as not to become broken or disarranged accidentally while the plane is in use, yet readily accessible for adjusting or changing the position of the plane-iron. Preferably the upward extensions of the surface of the rear wall of the opening in the stock are of metal, constituting integral parts of the plane-iron, and the supporting-frame of the plane mechanism is provided with a sole or wear plate receiving the wear of the plane and havinga throat for the play of the operative end of the plane-iron. The supporting-frame is also otherwise specially constructed at its lower end to cooperate with the said specially-constructed part of the surface of the front wall of the plane-opening to prevent uprising or dislodgment of said frame and the other parts of the plane mechanism supported or carried thereby, and preferably, also, the fastenings for the frame are introduced into the said duplicate metal extensions of the rear surface of the opening of the stock rather than in the stock itself. The construction enables use to be made of plane stocks or bodies of comparatively limited height and is otherwise especially advantageous, both from a commercial and practical point of view.

Specific reference being had to the accompanying drawings, wherein an embodiment of my invention is shown and which maybe the preferred embodiment, A represents the stock or body of the plane, constructed of any suitable wood for the purpose and formed therein at the proper point of its length with an opening a, the surface b of the rear wall of which is rearwardly and upwardly inclined at an angle of about forty-five degrees (45°) to the base of the plane, so as to give to the plane mechanism seated upon such surface the proper inclination within such opening. The lower corner of the front wall c of said opening a is also cut off or beveled to produce a similarly-inclined shorter surface d, which is preferably parallel with the said surface b, for the purpose hereinafter understood. In the top surface thereof the said plane stock or body is cut out or recessed a short distance centrally thereof, so as to provide a cavity e, leading rearwardly from the opening a and designed to partially receive the operating element of the up and down adjusting devices for the plane-iron in the manner shown and as hereinafter specifically set forth. Secured in place upon the upper portion of the stock or body by means of screws or similar fastenings f is the top iron B, which is constructed with parallel and slightly raised or elevated side portions g g, the inner surfaces of which may be practically flush or even with the corresponding surfaces of the sides of the opening a, already referred to. Said side portions g g are united by an integral rib h, connecting the same at about the upper forward edge of said opening a, and forwardly of said rib the said top iron is formed with a short longitudinal extension i, on which is seated the knob or forward handle j of the plane, said knob being held in place by a screw k, entering the stock through a suitable opening therefor in said forward extension. The rearward ends of the side portions g g of the top iron gradually decrease in height and slightly converge at l l, whence they terminate in parallel elevated flanges m m, formed on a rearward longitudinal extension n, and upon which latter, between said flanges, is seated the base o of the main or rear handle C of the plane, said handle being securely fastened in place by a screw-rod p, passing through the same and secured at its lower end in a threaded opening in the said extension n therefor. The forward part of said rearward extension it of the top iron is cut out or notched at n’, so as to bring the inner edges e’ thereof about even with the side and rearward edges of the recess or cavity e of the plane-stock, and thus are formed the integral flanges s s of the top iron, which are seated upon the upper surface of said stock on opposite sides of the said recess or cavity therein. Said flanges are each provided with a hole or opening for the passage of a screw t, which enters the stock on opposite sides of the median line of the width of the same, and thus is an extremely rigid and compact structure derived. Said side flanges s s of the top iron are each widened somewhat at s’, and they also constitute bases for preferably duplicate integral supports u u for the frame D of the plane mechanism E, said supports of course being also on opposite sides of the median line of the width of the plane and being integral at the outer sides thereof with the adjacent inner surfaces of the rear ends of the side portions g g of the top iron. In this way increased width or thickness of each of the said supports it is obtained for the formation therein of a threaded opening v for the reception of a screw w for securing the supporting-frame D in place and which construction does not materially add to the weight of the plane. The forward edges or faces x x of said supports u u are faced off in the same plane and at an upward and rearward inclination corresponding to the angle of inclination of the surface b of the rear wall of opening a in the stock, and thus said faces of the said supports constitute practical upward continuations or extensions of said surface b. In this way an increased, even, and continuous bearing-surface is obtained for the under side of the supporting-frame D of the plane mechanism, as is obvious. The frame D is substantially a rectangular plate the upper part d’ of which is comparatively thin, while the remaining lower portion thereof is of increased thickness, for the purpose hereinafter understood, although recessed or hollowed out, as at y y, on its upper surface, so as to lessen the weight thereof as much as possible without any less of strength. At its lower end the said supporting-frame is formed or provided with a sole d2, in which is formed transversely a throat d3 for the player working of the lower and operative end of the plane-iron F in a manner well known. Also formed with said frame and preferably on the upper part of said sole-plate forwardly of the throat therein is a wedge G, the forward surface of which is at a corresponding angle to the undercut or beveled portion d of the surface of the front wall of the said opening a in the stock. Formed on the under side of the frame D, about centrally thereof, is a pendent or hanging portion d5, having in its rear face a threaded opening in which works the inner end of an adjusting-screw d4, having thereon an operating-button d5, provided with collars 1 1, forming between them a circumferential groove 2, in which are received on opposite sides of said screw the ends of the furcated arm 3 of a swinging lever 4, having its bearing on a rod or pin 5 between short flanges 6 6, also formed on the under side of said frame, the end or nose of the shorter arm 7 of such lever protruding forwardly through an adjacent opening or slot 8 in the said frame, all as shown. The said elements constitute the usual or well-known vertical or up-and-down adjusting devices for the plane-iron F, and it will be seen that the same are brought to a comparatively low position with reference to the plane-stock, the operating-button d5 thereof extending partly into the cavity e of the stock, thus economizing greatly in the space consumed or occupied by said devices as a whole. Moreover, in virtue of the lower part of the frame D being of an increased thickness downwardly, beginning at a point somewhat below the point of suspension of the lever 4 thereon, said adjusting devices are thus carried forwardly a distance about equaling the difference of thickness between the two parts of said frame, and are thereby caused to be snugly housed in the space between the inclined extended bearings or supports u u. In this way the operation of the adjusting devices in question may be effected without difficulty, while at the same time they are prevented in large measure from breakage or disarrangement by contact with external objects in the handling of the plane. Above the opening or slot 8 in the upper part of frame D is a recess 9, in which works a button 10, carried on the end of the well-known form of laterally-adjusting lever 11 for the plane-iron pivoted at 12 on the frame, the said button engaging, as usual, the sides or edges of a longitudinal slot or opening 13 in said plane-iron. Screwing in to the said supporting frame or plate D ofthe frame mechanism, about centrally of the width thereof and at a point about corresponding to the upper surface of the plane-stock, is an upwardly and forwardly projecting screw 15, over which is fitted the plane-iron F, having secured thereto by means of screw 16 the ordinary top plate F2, and above the top plate and also fitting ever the screw by means of an opening or slot 17 therein is the usual clamping device or lever 18, with the edges of the said slot therein engaging under the head of said screw, the parts all being held together within the opening a of the stock by the clamping action of said clamping-lever 18 caused by the cam 19 when turned down against the top plate by means of its operating-lever 20, the said cam bearing directly upon a spring 21, secured on the under side of said clamping-lever and all operating in an obvious manner. Formed in the said supporting frame or plate D, on either side of the median line of the width thereof, are the slots er openings 25, the lower edge of each of which is substantially in the plane of the longer axis of screw 15, and the length of each of which is only suflicient for maximum vertical or up-and-down adjustments of the frame, whereby the sole d2 at the lower end thereof may be carried to any extent of protrusion beyond the under or wearing surface of the stock by which to practically receive and sustain the greater part of the wear of the plane in use. Said slots or openings 25 are also in direct line with the screw-holes v v in the extensions or supports u u, the original position of such openings prior to any adjustment of the frame being about midway the length of the slots, substantially as shown in Figs. 4 and 5, and the frame is chamfered or countersunk at 27 around the edges of said slots, so as to bring the heads of the fastening-screws w for the frame at least flush with or below the upper surface of the latter, and thereby enabling an even seating of the plane-iron upon said frame. From the construction and organization shown and described it will be seen that the fastening-screws w for the frame D are brought into the nearest practical proximity or relationship with the said forwardly-projecting screw 15, and thus is there partially established a counterbalance between the opposing forces acting separately on said screw 15 and the screws w, the one force tending to pull the frame outwardly or upwardly and the other tending to hold the frame (and consequently the entire frame mechanism) down upon its seat or bearing upon the stock within the opening a therein. Inasmuch, however, as the pressure or force exerted by cam 19 as well as that exerted by screws w are both on the same side of and above screw 15, which latter it will be understood is a fulcrum for the clamping bow or lever 18, there is a slight tendency to uprising of the lower end of the frame D, which tendency is successfully or effectually resisted by the forward inclined face of the wedge G firmly abutting or engaging the opposing inclined surface d of the lower part of the front wall of the said opening a, in the stock. In this way there is established a most perfect counterbalance or equilibrium of the forces acting upon the parts of the planes in different or opposing directions, thereby overcoming or preventing any tendency to vibration or chattering of the plane-iron irrespective of the degree of hardness of the wood upon which the plane is used.

It will be seen from the foregoing description, taken in connection with the accompanying illustrations, that I have provided a bench-plane possessing compactness and stability and one in which adjustments may be made readily and accurately without loss of time. The plane is strong and capable of withstanding all the handling incident to the conditions under which the same may be used, and the general commercial as well as practical advantages thereof will be apparent without further mention. It will be understood, of course, that I do not limit myself to the precise details of construction and organization of the elements of the plane, since changes may be made therein without departing from the spirit and scope of my invention.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bench-Planes, of which the following is a specification.

This invention relates to bench-planes; and it consists, substantially, in the improvements hereinafter more particularly described.

Considerable attention has been given in recent years to the construction and operation of bench-planes (both metal planes and wooden planes) with a view to increasing the general effectiveness and range of efficiency thereof, and more especially to the construction and organization of the elements or parts constituting the operative mechanism of the plane, as well as to the manner of seating and securing such mechanism within or upon the plane stock or body. Principal among the difficulties encountered in planes usually is the undue vibration or chattering of the edge or operative portion of the plane-iron, due largely to the drag or upward resistance offered by the surface of the wood operated upon, particularly in the case of hard woods. To overcome such chattering in a metal plane, it has been suggested to provide the upper surface of the sole of the plane with two steps, one raised or elevated above the other and the two constituting remotely-situated step-bearings for a so-called “frog” firmly held upon said bearings and flexed to thereby steady the same, and thus prevent chattering of the plane, while still permitting of adjustments of the plane-iron for varying the width of the throat of the plane. As is obvious, a construction or organization of the kind mentioned is not practicable with a plane having a wooden body; but, as hereinafter specifically explained, practically the same resuits are attained in a wooden plane by means of substantially the construction and organization of devices herein employed. Other difficulties and disadvantages have also been frequently met with in the construction and operation of the adjusting elements of the operative mechanisms of planes generally, I (both metal and wooden planes,) since in many embodiments hitherto devised or employed it is always diflicult and often practically impossible to effect the adjustment of one of such parts or elements without disarranging or dislocating the whole or some other part or parts of the mechanism and which is a decided objection for several reasons. Still further, in many instances hitherto the so-called “wooden planes” are both heavy for convenient use and comparatively expensive to manufacture on account of the considerable arnount of material employed in the construction of the essentially metallic portions thereof, and for which and other reasons the commercial advantages of the plane are greatly lessened as well as its utility.

The present invention has for its object to overcome all of the above-mentioned difficulties and disadvantages and to provide a bench-plane possessing the greatest stability between the several elements or parts thereof and also in which each part or element combines maximum strength with extreme lightness and delicacy of structure.

A further object is to greatly improve this class of tools generally, both from a commercial as well as from a practical standpoint, whereby the cost of the plane is reduced and the effectiveness and efficiency of the same enhanced over and above many planes hitherto devised with similar ends in view.

A further object of the present invention is to provide simple and effective means for preventing chattering of the operative portion of the plane-iron and also to provide a plane mechanism of great stability and compactness and one in which the up and down adjusting devices for the plane-iron may be set to any position desired irrespective of whether the said mechanism is in place within or upon the plane body or stock.

A still further object is to provide a plane mechanism adapted for use with plane stocks or bodies of dilferent standard sizes without requiring any change either in the adjustment or fastening of any of the elements thereof, all as will more fully hereinafter appear.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, wherein —

Figure 1 represents a longitudinal vertical sectional elevation of a bench-plane embodying my several improvements, said view being taken substantially on the median line of the plane. Fig. 2 is a top plan view of my improved bench-plane with the operative mechanism thereof detached or removed to more clearly indicate the construction of the plane-stock, as well as the inclined seats or supports which receive and cooperate with the uppermost projections or raised bearing-surfaces on the rear or under side of the adjustable supporting-frame of said operative mechanism. Fig. 3 is a longitudinal sectional view of the top iron of the plane, taken about centrally. Fig. 4 is an enlarged sectional view of my improved bench-plane, taken about on the same line as in Fig. 1, the stock or body of the plane being broken off at the ends. Fig. 5 is a view looking from the rear or under side of the adjustable supporting-frame for the operative mechanism of the plane (appurtenances being removed) to more clearly indicate the arrangement and location of the projections or raised bearing-surfaces on said frame. Fig. 6 is a sectional view on the line X X of Fig. 7 to indicate more clearly one of the slots and screws or similar fastenings by which the adjustable frame of the plane mechanism is confined in place upon the seats therefor, said view being minus the plane-iron and its adjusting devices, as well as the top plate and clamping bow or lever shown in Figs. 1 and 4. Fig. 7 is a vertical transverse sectional view looking toward the right of Fig. 1 and being partly broken away at one side to indicate one of the screw-holes in the plane-stock and also being minus the forwardly-adjusting device for the plane-iron, as well as said latter element and the top plate and clamping bow or lever shown in Figs. 1 and ft. Fig. 8 is a diagrammatic view illustrative of the adaptation of my improved plane mechanism to plane bodies or stocks of different sizes or dimensions.

Before proceeding with a more detailed description it may be stated that in carrying my invention into effect I provide the body or stock of the plane of any suitable wood adapted to the purpose, and I form therein an opening extending from top to bottom thereof for the reception of the operative mechanism of the plane, which mechanism comprises suitable ordinary adjusting devices for the plane-iron both in vertical and lateral directions. The said operative mechanism also includes an adjustable supporting-frame constructed with a sole-plate in which is formed the throat for the proper working of the cutting edge of the bit or plane-iron, and said sup porting-frame is otherwise constructed in the manner and for the purpose hereinafter specifically explained. When the elements of the operative mechanism of the plane ar properly adjusted relatively to each other and the supporting-frame thereof also adjusted and secured in place within the stock, opposing forces or strains are set up or established between the said frame and stock at different points, as vvell as between the frame and clamping-bow at substantially corresponding points, the tendency of such strains or forces in one direction being to firmly hold or press the remote bearing-surfaces of the frame to their supporting-seats and those in the other direction to dislodge or pull the frame therefrom, whereas in virtue of the peculiar construction and organization of the different cooperating parts the said forces tend to slightly bend or flex the frame between its bearings on the stock, and the resultant effect is to establish equilibrium and-perfect stability between the several elements ofthe plane mechanism, and thereby prevent vibrating action of the supporting-frame, and consequently effectually preventing or overcoming any tendency of the operative portion of the bit or plane-iron to chatter or vibrate in the use of the plane either upon hard or soft woods.

Through the vertical adjustments of the said supporting-plane for the plane mechanism the amount of protuberance or projection of the wearing-sole from the under or operating surface of the plane-stock may be varied or altered so as to receive practically much the greater part of the wear of the plane, and it will be apparent that in any of such adjustments the vertical position of the operative edge of the plane-iron will be correspondingly altered or changed. The lateral as well as the vertical adjustments of the plane-iron, however, are effected independently of the adjustments of said frame, and, as will be seen hereinafter, the devices for effecting the latter adjustments may be set before introducing or seating the plane mechanism within the stock. Moreover, the organization is such that even after the said plane mechanism is seated within the stock either one or all of the adjustments mentioned may be made without dislocation of any one or more of the elements or parts. My improved plane mechanism is complete in itself and constitutes a compact and stable structure adaptable to planes of different heights or dimensions within certain limits, and thus said mechanism may be kept “in stock” in large quantities and sold to the trade separately from the bodies of the planes, if desired. This also is a great advantage in that said mechanism may be applied to plane-bodies of one size or another either at the time of sale or when the planes are sent to market or else when substituting either a plane-body or one set of mechanism for another, as in instances of renewals and repairs.

Specific reference being had to the accompanying drawings, A represents an ordinary plane stock or body constructed of any suitable wood and formed at a suitable point in the length thereof with an opening a, extending from the upper surface b to the lower and operating surface, said opening being for the accommodation and working of the parts or elements of which the plane mechanism is made up or constituted. The surface of the front wall of the opening a may be straight at d for its full height, if desired, whereas at a suitable distance from the under side of the stock said wall is preferably undercut, so as to form a downwardly and forwardly inclined beveled surface e, as shown. The surface of the rear wall of said opening is inclined upwardly and rearwardly at f substantially at an angle of forty-five degrees (more or less) from the point g of the stock, thus decreasing the length of the opening toward the bottom of the stock, as shown, the width of said opening between the sides of the stock being of equal extent throughout. The beveled or inclined surfaces e and f are parallel with each other, the said surface f being longer or higher than the surface e and serving not only to position the plane mechanism within the stock, but also in part as a seat and resistance for the lower end of the adjustable supporting-frame of the plane mechanism, to be hereinafter described.

Secured to the upper surface of the stock or body of the plane in any suitable manner, and preferably by means of screws, such as h, is the top iron C, constructed of a single piece and formed with the slightly-elevated centrally-disposed side portions i i, connected together at the upper edge of the forward wall of opening a of the stock by means of a slightly-raised rib j, said side portions having their inner surfaces substantially even or flush with the inner surfaces of the two sides of said opening, while the outer surfaces thereof are preferably somewhat within the side or corresponding surfaces of the plane-stock, this construction tending to greater strength and more equal distribution of weight and strain throughout the plane structure. The said side portions i i of the plane-iron extend rearwardly a suitable distance beyond the upper edge of the rearwardly-inclined surface of the rear wall of said opening a of the stock, and they are turned or inclined inwardly at k k, whence they merge or terminate in parallel strengthening-flanges l l, between which is snugly seated the elongated base in of the rear handle n of the plane. The said handle n is securely fastened in place by means of a rod o passing down through the same, and the lower-threaded end of which is received in a projection o’ on the top iron, having a similarly-threaded opening to receive it, said rod being provided with a screw-cap o” at its upper end fitting a countersink at the upper surface fn’ of the handle. From this construction it will be seen that the said handle is securely braced against lateral strains in the manipulation of the plane and that the fastening therefor is also largely relieved of such strains, thereby tending to greater effectiveness and security of fastening. Seated upon the forward flanged portion i2 of the top iron is the forward knob or handle i3, secured in place by one of the screws h, entering the stock or body A, as shown.

Situated upon the upper surface of the plane stock or body A, intermediate or between the raised side portions of the top iron C, are preferably two seats or supports s s, which are each substantially pyramidal in side view, with the upwardly and rearwardly inclined edges or faces s’ s’ thereof preferably flush with and constituting practical extensions or continuations of the said upwardly and rearwardly inclined surface f of the opening of of the stock, said seats also cooperating with the supporting-frame of the plane mechanism, as already suggested and to be presently explained. These seats s s may be mounted in position in various different ways; but preferably I provide bases s2 s2 therefor, joined together by an integral connecting base portion s3, and said bases are also in turn preferably integral with the corresponding side portions i i of the top iron, as indicated at s4 s4. The bases are firmly held in position upon the upper surface of the plane-stock, (as are the remaining portions of the top iron C,) and from the construction and organization herein shown it will be seen that an eminently strong and stable structure is had or obtained. Said inclined seats by being thus widely separated from each other enable a great saving to be had in the amount of metal employed in their construction, and an additional saving of metal is also derived in dispensing with any connection between the outer sides of the seats and the opposing inner sides of the top iron, excepting at the bases s2 s2, as already described. In this way also the structure is rendered considerably lighter without loss of strength, while the space between the said inclined seats is utilized to partially receive and accommodate the working of the vertically-adjusting devices for the plane-iron, as will hereinafter appear.

Formed in the rearwardly and upwardly inclined wall f of the opening a of the stock or body A and at predetermined points on opposite sides of the median line of the width of the plane are suitable openings f2 f2, (see Fig. 2,) which extend into said body or stock substantially at right angles to such inclined surface, said openings each being for the reception of means, such as a screw u, for securing the supporting-frame D of the plane mechanism B firmly in place. Said supporting-frame comprises, essentially, a substantially rectangular plate having therein suitable oblong slots or openings v v, (see Fig. 5,) through which pass the fastening-screws u, (but one being shown,) the said slots or openings being for the purpose of enabling the said supporting-frame to be moved or adjusted on the screws with respect to the plane-stock. The entrances to the openings f2 f2 in the stock are at the highest available point of the stock by which to bring the heads of the screws as close as practicable to and yet below the axis of the forwardly-projecting screw E, which fits in said plate in line with the transverse center thereof. The purpose of this organization will be fully understood hereinafter, and it may be stated at this point that the base portion s3 of the top iron, as well as the upper surface of the plane-stock, are each preferably correspondingly notched or out out at y y’, by which to accommodate the inner end of said screw E in the event of any inward adjustments thereof being made at any time, though in most instances said notches may be dispensed with. It may also be here added that the upper surface of frame D is sunken or recessed at v’ v’, so as to bring the outer surface of the heads of said screws it in a plane at least flush with or slightly below the highest parts of the frame-surface to thus enable the proper seating in place of the plane-iron D2, hereinafter referred to. The said supporting-frame D is made very thin and strong, as will be observed, and to further reduce the weight thereof it is preferably channeled out on the upper surface, as shown at z, for instance, thereby leaving slightly-raised surfaces ,z’ z2 z3, and z4, and upon which rests the under surface of said plane-iron, this latter element having an opening for the passage of screw E, and leading from which opening is the usual slot 2, between the sides of which extend the effective portions of the usual lateral and vertical adjusting devices for the plane-iron. The said frame D is also sunken in its upper surface just above screw E to form a recess 3 for the accommodation of the head 4 of the screw which secures the top plate 4a to the plane-iron, and said plane-iron and said top plate each has the usual slot or opening 5 5a in which works the end of the upper arm 6 of the swinging yoke-lever 8, the ends of the furcated arm 9 of which are engaged by collars 10 11 on a sleeve working on a screw 12, fitted in a threaded opening in a bearing 13 on the under side of frame D and having a head 14 for manipulation thereof. These elements constitute well-known vertical adjusting devices for the plane-iron; but attention is called to the compact organization herein shown and provided whereby said bearing for the adjusting-screw is accommodated between the elevated inclined seats 5 3 on the upper surface of the plane-stock. Pivoted at 15 upon the upper surface of frame D is the usual laterally-adjusting lever 16 for the plane-iron, said lever having the button 17, engaging the sides of slot 2 of said iron, while secured in place upon the said top plate 4a is the usual clamping-bow 18, having therein a slot 19, the edges of which are engaged by the head of screw E, the said bow having on its under side a spring 20, which is forced against the upper surface of the top plate 4a by means of a cam 21 on a lever 22, working in the upper end of the bow in a well-known way, the action of said cam at the same time being to throw the upper end of the bow upwardly or outwardly from said top plate. By turning said cam-lever upwardly or outwardly the parts are loosened sufficiently to enable any desired adjustments of the plane-iron to be made, or the elements above the frame D may then be temporarily removed for the purpose of adjusting the said frame upon its fastening-screws.

The supporting-frame D for the plane mechanism is formed with a wearing-sole 25, having therein the throat 26 for the cutting or operative end of the plane-iron, and immediately in front of the throat said sole is constructed with a wedge 27, extending the full width of the opening a in the stock, the forward inclined face 28 of which wedge snugly fits against the undercut or bevel e of said stock. Said wedge is united or connected with the forward or upper surface of the frame mechanism, at the edges thereof, by means of integral side plates 30, as shown, and it will be seen that one of the principal reasons for the adjustability of the said supporting-frame D is to enable the sole to be so adjusted with reference to the under or working face of the plane as to practically receive all the wear of the plane. As the sole itself wears it can be readily adjusted in compensation therefor, as is evident. Said supporting-frame D is formed on its under surface, at the lower end thereof, with a slightly-projected bearing-surface 31, extending all the way across the frame and which has its seat upon the lower part of the inclined surface f of the rear wall of opening a in the stock, it being understood, of course, that said bearing-surface is planed or dressed off parallel with said beveled or inclined surfaces e and f, and the supporting-frame itself being also parallel therewith, so as to occupy the necessary inclined position upon the plane. Also formed on the under side of said frame D at points substantially opposite the forward inclined edges or faces of the inclined seats or supports s s of the top iron are similarly-projected bearing-surfaces 32 32, (see Fig. 5,) which rest and have a firm bearing upon said seats or supports s s, the median line of the width of such surfaces being somewhat outside median lines passing between the vertical edges of each of said slots v v, this construction aiding in the flenure or bending of the frame intermediate its supports or bearings, as is evident.

To assemble the parts of the plane, the frame D is placed within the opening a of the stock, with the bearing-surfaces 31 and 32 32 thereof resting upon the several seats therefor already described, and the screws u are screwed down very tightly upon the frame after the latter has been adjusted to bring the sole-plate thereof to the desired position relatively to the bottom surface of the stock. The top iron and its plate may now be placed in position by slipping the same over the screw E, after which the clamping lever or bow is also applied in similar manner, and the cam-lever 22 is then turned downward, so as to throw the upperend of said clamping-lever outward or upward, while the spring on the under side thereof is forced against the top plate by the cam, thus holding the elements of the plane mechanism together very rigidly. In virtue of the construction of my improved supporting-frame D and cooperation between the remote bearing-surfaces thereof and the corresponding seats therefor upon the plane-stock the said frame is firmly and securely held down by means of its screws in a manner quite evident. At the same time the cam 21 is exerting a downward pressure upon the upper part of the plane-iron and its top plate, which pressure is of course communicated to and thrown upon the frame above its uppermost bearings, and simultaneously with this action the lower end of the clamping-lever is thrown downward upon the lower part of the top plate by the cam, thus exerting a counterbalancing downward pressure on this end of the supporting-frame, the head of screw E obviously operating all the while as a fulcrum for the clamping bow or lever to work on. Due to the upward and downward positions to which the ends of the clamping-bow are thrown and held by the cam 21 considerable of an outward strain is placed upon said screw E and which exerts an outward pull upon the frame D, tending to lift the latter from the remotely-situated seats therefor and which is counter to the downward pressure exerted by the screws it and the bow and cam-lever to hold the plane in place. The opposing forces thus set up tend to the establishment of perfect equilibrium between the parts and result in a bench-plane possessing the greatest stability and practicability and one in which chattering of the plane-iron is practically destroyed or overcome, due to the inherent tension at which the frame D is always held.

In some instances the present construction may be modified, to form the bearing-surfaces 31 32 32 on the stock itself and raised or elevated with reference to and parallel with the inclined surface f of the opening a in the said stock, in which case the entire lower or under surface of frame D would be formed, preferably, even or flat. A further modified construction also would be to form the inclined seats s s for the frame integral with the plane-stock rather than with the top iron; but thc construction or embodiment herein shown, however, is the one preferred in practice.

As already explained, the plane mechanism of my present invention is compactly organized and is removable in entirety from the stock and adapted to be sold to the trade separately from the stock, being also adapted to plane-stocks or bodies of different sizes, as is clearly shown in the diagrammatic view, Fig. 8. As is well known, there is but slight variation in the heights of the plane-stocks of different standard sizes per series, even though the length thereof may vary considerably, and thus, as will be clearly seen, one or the other of the stocks may be employed with the same mechanism. As is equally apparent, my improved plane-stock may also be supplied to the trade separately from the plane mechanism, but preferably provided with the top iron.

My invention thus comprises a construction and organization of elements cooperating in the production of a bench-plane supplying in ample measure practically all the present-day requirements of such a structure, both as regards its utility as well as the operational, practical, and commercial advantages thereof.

To all whom it may concern:

Be it known that I, LUCAS C. CLARK, a citizen of the United States of America, residing at Southington, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement Applicable to Planes, of which the following is a description, reference being had to the accompanying drawings, wherein —

Figure 1 is a perspective view of a complete tool embodying said improvement. Fig. 2 is a perspective view of an adjustable leaf and appurtenances by which it may be attached to a common style of plane. Fig. 2a is a view of a portion of the plane-face and of the adjustable leaf with a portion of the latter broken away. Fig. 3 is a perspective view of one end of the adjustable leaf and appurtenances carried thereby. Fig. 4 is a perspective view of the disk-section peripherally worm-toothed and the attached plate adapted to be screwed, bolted, or otherwise fastened to a common plane. Fig. 5 is a cross-sectional view on the plane x x looking in the direction indicated by the arrow with the adjustable leaf and the plane-face adjusted at an angle of forty-five degrees each to the other. Fig. 6 is a view similar to Fig. 5 with the adjustable leaf and plane-face adjusted at an angle of thirty degrees each to the other. Fig. 7 is a perspective view of an end of the adjustable leaf attached to the rim-sector. Fig. 8 is a view similar to Fig. 5, showing the adjustable leaf in a curved form.

The object of the improvement is the production of a plane having a pivotally-attached adjustable leaf which within reasonable limits can be adjusted at any desired angle to the plane-face, the adjustable leaf acting in use as a guide for the plane for a variety of purposes.

In the accompanying drawings the letter a denotes the plane as a whole, and a’ denotes the cutter of the plane.

b denotes an adjustable leaf pivotally attached to the plane.

c denotes what may be termed “rim-sectors” made fast to the adjustable leaf in any suitable manner.

d denotes disk-sections lying within the rim part of the rim-sectors.

e denotes plates fast to the disk-sections and adapted to be screwed, bolted, or otherwise properly secured to the plane.

f denotes an operating-worm carried by a rim -sector, and d’ denotes worm-teeth on the periphery of a disk-section cooperating with said worm. It will readily be understood that by rotating the worm the adjustable leaf can be rotarily adjusted. The rim-sector carries on one edge one or more graduations, and the face of the disk-section carries corresponding graduations or figures, preferably the latter. Preferably one edge of the adjustable leaf is always overhung by the plane-face, and also, preferably, that same edge of the plane-face is always substantially in contact with the plane-face. These words “substantially in contact” do not mean actual contact, but something very closely akin to it, as near akin to it as is practicable for ordinary uses. It is also preferable that the said edge of the adjustable leaf be always overhung by the edge of the cutter of the plane. The adjustable leaf has by preference a flat face, but is susceptible of faces of other forms — as, for instance, the curved face shown in Fig. 8.

It will be readily understood that the worm might be attached to the disk-section and cooperate with worm-teeth on the rim-sector. The letters g and h denote parts of a screw-clamp for holding the adjustable leaf firmly in any position in which it may be set.

I claim as my improvement —

1. In combination, the plane, the adjustable leaf, the rim-sectors attached to the leaf, and the disk-sections within the rims of the rim-sectors, and attached mediately to the plane, all substantially as described and for the purposes set forth.

2. In combination, the plane, the adjustable leaf, the rim-sectors attached to the leaf, the disk-sections within the rims of the rim-sectors, and the planes attached to the disk-sections and adapted for attachment to and detachment from the plane, all substantially as described and for the purposes set forth.

3. In combination, the plane, the adjustable leaf, a rim-sector attached to the leaf, the worm borne by the rim-sector and the disk-section attached to the plane and peripherally worm-toothed, all substantially as described and for the purposes set forth.

To all whom it may concern:

Be it known that we, JUSTUS A. TRAUT and HENRY S. WALTER, citizens of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Plane-Iron Caps, of which the following is a full, clear, and exact description.

Our invention relates to improvements in planes, and particularly to plane-iron caps.

It consists, mainly, in the improvement of what is termed the “cap-iron” or “cap-piece” in that class of planes in which the plane-iron is clamped to a frog by means of a screw or cam. By this invention we are able to construct a plane-iron cap much cheaper than heretofore and more efficient and durable, as well as more adaptable to the uses to which it may be put.

In the drawings, Figure l is a side elevation of a plane embodying our invention. Fig. 2 is a plan view of that part of the plane to which our invention relates. Fig. 3 is a longitudinal section on the center line of Fig. 2. Fig. 4 is a cross-section on the line X X of Fig. 2 looking in the direction of the arrows.

1 is a plane-stock.

2 is a plane-iron.

3 is a forward handle.

4 is a rear handle.

5 is what is commonly termed a “cap-screw, secured to a frog or support 6 for the plane-iron. The cap-iron 9 is so shaped and constructed as to be engaged at an intermediate point by the head of the screw 5 and at each end to bear upon the plane-iron or a plate, such as commonly associated therewith. In the drawings, Fig. 1, the cap is shown as engaging the forward or lower edge of the plane-iron and engaging the upper portion by means of a cam-pressed spring 7, 8 being the cam employed for clamping the parts. Thus far described the construction and operation of the parts are well known, and hence need not be described in detail.

In practice it is essential that the cap-iron shall be very strong and desirable that it be light in weight, and to that end I construct it, preferably, of wrought or sheet metal. The cap-iron includes a broad blade-like portion 91 and a narrower shank 10. The lower edge of the portion 91 engages with the plane-iron or a part thereof near the cutting edge, while the cam 8 is carried on the shank portion 10. The cap then is subjected to strains in a manner similar to a beam supported at the ends and loaded in the middle. For this reason in order to provide sufficient strength the edges of the shank 10 and a portion of the broader part 9 of the plane-iron are bent down at an angle to provide side bars or flanges 101 integral with the body portion of the plane-iron, and hence contributing to the plane-iron great rigidity and strength. Furthermore, the flanges provide a recess in which to receive the pivot-bearing 81 for the cam 8. In addition to this feature of construction, which contributes substantially to the strength of the cap-iron, we provide a corrugation 11, which preferably commences in the shank portion 10 of the cap-iron and extends downwardly toward the broader portion on opposite lines. In addition to these corrugations shorter corrugations 12 12 may be provided in the broader portion of the cap-iron, contributing vastly to the rigidity and strength of the device, which is preferably curved, as shown best in the side views numbered 1 and 3. The particular construction preserves the curved outline of the cap-iron and permits the employment of comparatively light wrought or sheet metal. The flanges 101 form a pocket in which to receive one end of the spring 7, which is preferably fixedly secured to the cap-iron, as well as a pocket for the bearing end of the cam 8 adjacent to the pivot or pin 81, upon which said cam turns. All of the ribs or corrugations extend generally in a longitudinal direction relatively to the cap-piece, and consequently give greater rigidity to it in a lengthwise direction than transversely.

It is advantageous to have the greater strength extend in longitudinal lines. Should the gage of the metal employed in shaping the cap-piece be so light as to permit any flexibility, it would be in a transverse direction at the lower edge only, and hence advantageous in permitting the lower edge of said cap-piece to yield and bear uniformly against the plane-iron or the plane-iron plate, which is usually employed therewith in planes of the class to which our invention is particularly applicable. In Fig. 4 it will be seen that the ribs are preferably hollowed on the under side, the said view showing the under side of said cap-piece uppermost.

What we claim, and desire to secure by Letters Patent, is —

1. In a plane, a cap-iron having flanges on opposite sides at its upper end, and ribs extending longitudinally of said iron.

2. A plane-iron cap for a plane having corrugations or ribs extending longitudinally thereof, substantially as described.

3. A plane-iron cap for a plane having corrugations or ribs 12 and 12 in the body and extending longitudinally thereof, as described.

4. A plane-iron cap for a plane having corrugations or ribs 11 extending up the shank and 12, 12 in the body extending longitudinally thereof, substantially as described.

To all whom it may concern:

Be it known that I, ALIX W. STANLEY, a citizen of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes.

The object of this invention is to provide a construction by which the support for the cutting-iron shall be such that the chattering of said iron in use is entirely prevented. In planes of this character the support for the cutting tool or iron is termed a “frog,” and the frog is commonly made in a piece separate from the body or stock of the plane. The reasons for this are several, among which is that an adjustability is permitted whereby the effective size of the opening or throat in the stock or base of the plane through which the cutting-iron works may be narrowed or widened, as desired, according to the character of the work. Another is that the frogs are provided with the adjusting device, and it is more convenient to equip said frogs with said adjusting devices when they are separate from the stocks than would be the case if they were integral with the same.

The accompanying drawings show the preferred form of the invention.

In said drawings, Figure 1 is a side elevation, partly in section, of a plane embodying my invention. Fig. 2 is a plan view of the base or stock portion of the plane with the frog, cutting-iron, and the associated parts removed. Fig. 3 is a similar view of a modification. Fig. 4 is a perspective view of a frog such as is adapted for use in connection with the stock shown in Figs. 1 and 2. Fig. 5 is a perspective view of a modified form of frog adapted for use in connection with the stock or frame shown in Fig. 3.

In the particular form shown, 1 is the floor or sole of the stock portion.

2 2 are side walls or flanges.

3 is a throat or slot in the bottom or floor 1 of the stock.

4 is a frog which is supported, preferably, on two seats or bearings. These seats may comprise an elevated chair 5 and a bearing 6 upon the floor 1. The bearing 6 is formed by thinning down the floor 1 directly to the rear of the throat 3. This thinning down may be effected in casting the stock, (for it is by the casting process that stocks are ordinarily made,) or it may be formed by machine-work after the casting is produced. The purpose of making the bearing 6 thin will hereinafter be explained.

7 7 are screw-passages in the frog, preferably elongated so as to permit the frog to be adjusted forward or back, thereby changing the position of the cutting edge of the plane-iron in the throat 3.

8 8 are clamp-screws (two are preferably used) by which the frog 4 is secured to the stock. The clamp-screws 8 are located between the elevated bearing 5 and the bearing 6 for the frog, so that when the screws are set down they will firmly clamp said frog against both of said bearings 5 and 6. In consequence of the fact that these bearings are spaced apart considerably when the parts are assembled it is impossible for the frog to chatter upon the stock. By loosening the screws 8 the frog may be moved backward or forward, as desired, to place the cutting edge of the plane-iron correctly relatively to the throat 3.

9 is the plane-iron, the lower edge of which is sharpened in the usual manner and is caused to project through the throat as desired. It is preferred that separate adjusting devices be provided to facilitate the longitudinal positioning of the plane-iron.

10 is a cap of the ordinary form carrying the cam 11, also of the ordinary form, and 12 is a cap-screw carried by the frog 4., which projects through a slot in the plane-iron 9 and engages the cap 10 in the usual manner, so that when the parts are assembled the plane-iron is clamped in proper position.

Manifestly the method of clamping the plane-iron to the frog may be varied as desired, since the particular device for accomplishing this end constitutes no part of this invention, excepting as it is obvious that the clamping means should take a long bearing upon the plane-iron to hold it in proper engagement throughout substantially the full bearing-surface of the frog 4.

Inasmuch as the frog is independent of the stock and inasmuch as the clamping effect of the screw 8 is considerable and inasmuch as the bottom 1 directly to the rear of the throat 3 is thin, the clamping effect of the screw 8 might tend to slightly bulge the said thin portion of the door, since this portion preferably affords one of the bearings for the frog. In order to prevent this bulging, I provide a supporting and stiffening rib 13, which in its preferred form is cast integral with the stock of the plane and preferably so as to extend from said thin portion to a heavier portion of the stock. Any desired number of these strengthening-ribs maybe provided. In Fig. 2 one of these ribs 13 is shown. In Fig. 3 two ribs 13 13 are provided; otherwise the construction is identical. I mention this, because it is obvious that the number of stiffening-ribs employed is immaterial. In order to permit the frog to take a proper bearing, I channel out the under side of the frog directly above the strengthening-ribs 13, so that the frog will not encounter the rib when the parts are assembled, but will take its proper bearing upon the seat 6. Manifestly this construction may be modified in a variety of ways.

In operation it is obvious that unless an efficient bearing is provided for the member or members which support the cutting-iron the passing of the plane over the material to be smoothed or cut might cause a vibration and a chattering of the parts. It is therefore desirable to have the forward bearing or point of contact which the plane-iron takes with the stock or parts associate therewith as close to the cutting edge as possible. Heretofore no special attention has been paid to thinning the metal of the stock directly to the rear of the throat. By thinning the metal at this point as I have done the frog supports the plane-iron almost down to its lower edge. In fact, when the best effect is produced the only unsupported portion is the beveled portion formed in shaping the edge. This will be seen in the section Fig. I. While this is of advantage generally, it is of particular advantage in that type of planes wherein the frog is adjustable longitudinally of the plane, so as to widen or narrow the throat, or rather that portion of the throat forward of the cutting edge of the plane-iron. By this invention in its preferred form a greater range of adjustability is rendered possible, since the frog may be moved to the rear of the throat to a considerable extent before the knife or cutting-iron will touch the metal of the stock. This is due to the fact that the metal of the stock may be made so thin at this point that the cutting-iron will not engage it, excepting at a point very close to its cutting edge. As a direct consequence the plane-iron may be adjusted forward or backward substantially the full width of the throat and still have an unimpaired and effective bearing directly upon the frog.

While I have shown and described a preferred form for the door of the stock to the rear of the throat, it is obvious that this may be modified in a variety of ways without departing from the spirit and scope of my invention, which in this respect relates to the provision of a suitable strengthening means adapted to reinforce the door immediately to the rear of the throat, so that that portion may be made thin, while the portion farther to the rear is of sufficient thickness to be self-supporting.

What I claim is —

1. In a plane, the combination with the stock, a frog, a plurality of bearings on said stock for said frog, and a clamping device located between said bearings, a slot or throat in the bottom or door of said stock portion, the bottom or door of said stock portion to the rear of said throat being thinned out up to the edge thereof, and means for strengthening said thinned-out floor.

In a plane, the combination with a stock having a plurality of seats for a detachable frog of a throat extending transversely of the stock and in the bottom thereof, the door of said stock directly to the rear of said throat being of thin metal, and strengthening-ribs extending from the heavy part of said stock to said thinned-out portion, substantially as described.

3. A stock for a plane having a transverse slot therein forming a throat for the passage of the plane-iron, the door to the rear of said throat being thin, the stock to the rear of said thin portion of the door being heavy, and a rib extending from said heavy portion to said thin portion, and strengthening and supporting the latter.

4. In a plane, a stock, a transverse slot therein forming a throat for the passage of the plane-iron, the door to the rear of said throat being thin, the stock to the rear of said thin portion of the door being heavy, and a plurality of ribs extending from said heavy portion to said thin portion, and strengthening and supporting the latter.

5. A plane having a stock portion provided with a throat, a frog, said stock portion being provided with two bearings for said frog, a rib connecting said two bearings, said frog being correspondingly grooved.

6. A plane having a stock portion provided with a throat, a frog, said stock portion being provided with an upper and a lower bearing for said frog, a rib connecting said two bearings, said frog being correspondingly grooved.

A plane having a stock portion provided with a throat, a frog, said stock portion being provided with an upper and a lower bearing for said frog, a screw having a seat between said bearings for securing said frog to said stock, a rib connecting said two bearings, said frog being correspondingly grooved.

To all whom it may concern:

Be it known that we, CHARLES E. RIECKER and HENRY S. WALTER, citizens of the United States, residing at New Britain, in the county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Plane-Lifts, of which the following is a full, clear, and exact description.

Our invention relates to planes, and particularly to improvements in carpenters’ or bench planes.

The purpose of the invention is to provide a simple and effective device to mechanically elevate or assist in lifting the plane on the return stroke, so that the cutting edge of the plane iron or knife will not become dulled by rubbing backward against the wood. The device, moreover, is so constructed as to be readily applied to a plane and to operate without chattering.

In the drawings, Figure 1 is a side elevation of a plane embodying our invention when on the return stroke. Fig. 2 is a similar view, partly in section, showing the position of the parts on the forward or cutting stroke. Fig. 3 is a plan view of the front end of a plane as shown in Fig. 1, the front handle or knob being removed. Fig. 4 is a perspective view of a device adapted to be attached to a plane for effecting the results herein desired.

The particular construction of the plane proper is immaterial and will not, therefore, be described in detail, since this invention is applicable to planes in general.

A represents the body or stock of a plane, and in the particular construction shown B is a front handle, and C a rear handle. The operator usually grasps both handles of the plane in using the same. On the forward stroke of the plane the cutting is edected by means of a plane iron or knife D, which projects through a throat or passage in the stock A and slightly below the sole thereof. On the rearward or return stroke, if the plane-iron bears against the wood the cutting edge is rubbed backward and rendered dull. To avoid this, I provide a mechanical elevator in the form of a spring-pressed nose E, which is preferably carried at one end of the stock A in such a manner as to normally project slightly below the sole of the stock, and thus lift the stock a sufficient distance to free the cutting edge of the plane-iron D from the wood on the return stroke. In the particular form shown in the drawings the lifting device or nose E is shaped to the forward end of the sole and is carried by blade-springs F F, secured to a washer-like carrier G, which surrounds the stem or post upon which the forward handle B is mounted. When the handle is screwed down into place, it clamps the carrier G firmly in the position indicated in the drawings, Figs. 1 and 2. The lower edge of the nose of the lifting device E is preferably rounded or suitably fashioned so as not to scratch or injure the woodwork with which it comes in contact and to insure a smooth and noiseless action. In use the operator presses down upon the front knob of the plane in such manner as to overcome the lifting tendency of the elevator E and so as to bring the knife D into proper contact with the wood. As the plane is advanced the knife cleaves the wood and cuts of a shaving of the desired thickness. Upon the return stroke the natural tendency of the user is to relieve the pressure upon the plane and, in fact, to apply a slight lifting tendency. As this lifting tendency is not usually sufficient to elevate the plane from the wood, so as to relieve the engagement of the knife therewith, it is supplemented by a mechanical appliance, herein described, to a sufficient extent to cause the sole of the plane to be elevated to the desired degree, thus prolonging the effective life of the cutting edge of the plane-iron. The method of attaching the elevating device E is preferentially shown; but it is manifest that it may be modified in a variety of ways. As shown, the elevating device takes a long bearing upon the wood substantially the full width of the sole, and hence prevents the tilting of the plane on its rearward movement and effectively elevates the entire cutting edge of the plane, so as to substantially relieve the pressure of the knife-edge against the woodwork upon the return stroke of the plane.

It is obvious that this invention may be applied to any plane of this general type without any alteration to the plane whatsoever. The plane-lift maybe manufactured and sold separately to be attached to any plane. The construction is such that chattering is prevented when the device is in use. This partially results from the fact that the nose is carried at the end of the plane-body, and its supporting or carrying blades F F project rearwardly, so that when the plane is drawn backward, at which time the pressure on the same is very slight, the friction occurs in a direction away from the point of support, so that the action is smooth and uninterrupted. When, on the other hand, the plane is pushed forward, the pressure on the handles is considerable, so that although the friction upon the nose does occur in the opposite direction the force applied is such as to prevent chattering.

What we claim, and desire to secure by Letters Patent, is —

1. In a plane, an elevating device projecting beyond the front end of the plane and means of connection between said elevating device and a portion of the plane, and means to normally cause said elevating device to project below the sole of the plane.

2. In a plane, an elevating device projecting beyond the end of the plane and means of connection between said elevating device and a portion of the plane, and a spring to normally cause said elevating device to project below the sole of the plane.

3. A plane having a front and a rear handle, an elevating device secured to the plane by the front handle said connection includiing a yielding spring-blade.

4. In a plane, a yielding elevating device comprising a nose mounted on the plane in front of the forward end thereof, and a spring for normally causing said elevating device to project below the sole of the plane, the operative edge of said elevating device being rounded.

5. An elevating device for a plane comprising a carrier, blades projecting forwardly therefrom and carrying a nose portion projecting downward therefrom, substantially as described.

6. An elevating device fora plane comprising a carrier portion G, a downwardly-projecting nose portion E, and means for connecting said carrier and said nose portion.

7. An elevating device for a plane comprising a downwardly-projecting nose portion, adapted to project beyond the end of a plane, a spring-blade attached thereto and means carried by said blade portion whereby said elevating device may be attached to a plane on top of its sole portion.

GROOVING-PLANE.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Grooving-Planes, of which the following is a specification.

This invention relates to planes; and it consists substantially in the improvements hereinafter particularly described.

The invention has reference more especially to planes such as are employed for cutting or forming grooves in the surfaces of wood and other materials; and the principal object of the invention is to provide a plane of this character with means for effecting the cutting or formation in the surface of the work operated upon of grooves having sides or walls which are curved from end to end, and also to provide means for insuring the evenness of cut or formation of the angular edges of the grooves, as well as the bases and sides thereof.

A further object is to provide a grooving-plane of this special character with means for maintaining or preserving the true curviinear path of the cutting devices of the plane throughout the full extent of the grooves formed thereby, and also to provide means whereby the plane may be readily adapted to the cutting or formation of grooves having sides or walls of different or varying degrees of curvature.

A still further object of the invention is to provide a plane of this character which is exceedingly simple and easily handled in the performance of the work required of it, and also to provide means for meeting all requirements of use of the plane.

The above and additional objects are attained by means substantially such as are illustrated in the accompanying drawings, in which —

Figure 1 is a view in perspective of a grooving-plane structure embodying the essential features of my improvements, the said plane being shown as applied for use in the cutting or formation of curved grooves in the surface of a block of wood or other piece of work operated upon; and Fig. 2 is a bottom plan view of the plane structure, showing an element of my improvements which is omitted from Fig. 1 for the purpose of clearness. Fig. 3 is an enlarged bottom plan view in detail of the cutting devices to more clearly indicate the organization thereof for effecting their respective functions. Fig. 4 is a view in perspective of a part of the gage of the plane, showing a modification thereof for enabling the formation in the work operated upon of grooves having sides or walls of less than a predetermined curvature from end to end.

Before proceeding with a more detailed description it may be stated that while I have herein provided an ordinary grooving-plane with special means for the cutting of grooves having sides or walls which are curved from end to end it will be understood that the adaptability or capacity of the plane for cutting grooves having straight sides or walls from end to end is not altered in the slightest respect. Hence the greater advantage of my improvements. With some kinds of planes for cutting or forming straight-sided grooves in the work operated upon it is usual to employ a suitable gage having a straight edge or face for moving upon or against a corresponding straight edge or face formed on the adjacent part of the work, the said gage serving to guide the cutting devices evenly and being adjustable, by which to vary the distance of the grooves from the edges of the work as well as from each other.

In constructing a grooving-plane according to my present improvements I may employ a well-known form of plane having at one side thereof an adjustable gage formed with a straight edge extending substantially parallel with the sides of the plane-stock, and to said straight edge I apply one or more specially-constructed lateral bearings for the plane structure, said bearings being designed to work upon or against one side or edge of the work in the formation of grooves having either straight or curved sides or walls. For the cutting or formation of straight-sided grooves the adjacent side or edge of the work is made straight, while for the cutting or formation of grooves having curved sides the adjacent side or edge of the work operated upon is constructed in correspondence with the desired degree of curvature of the sides of the grooves to be formed, and it may be stated that the plane structure is equally operative whether the lateral bearings referred to are applied to a concave surface or to a convex surface. In either case the plane structure is constantly deflected to one side in a manner to cause the cutting edge of the bit or plane-iron to follow the desired curvilinear path, and it may be stated that such constant deflection causes the effective edge of the said bit or plane-iron to operate upon the work with a glancing or shearing cut, which is much more effective in removing the necessary quantities of material for the production of the grooves. It may also be stated that in order to insure the evenness of cut of the angular edges of the curved grooves I provide suitable scorers or cutting devices in advance of and slightly beyond the ends of the cutting edge of the plane-iron or bit, said devices operating in a manner and for the purpose hereinafter more fully understood.

Specific reference being had to the accompanying drawings, A represents a grooving-plane embodying my improvements, the same comprising a stock a, having a suitable grip or handle b and provided with the usual bit or plane-iron c, the effective or cutting edge of which is indicated at d. Attached or secured to one side of said stock a is a bracket B, which is provided at points in advance and to the rear of the said cutting edge d with bearings e e, which receive the inner end portions of parallel bars or rods f f, on which are slidably fitted the sleeve portions g g of a guide or gage C, said gage being of ordinary form and constructed with a straight edge or surface h adjacent the said plane-stock a, said sleeve portions being each provided with a set-screw i, working in the side thereof, the said screws being forthe purpose of tightening the gage in diiferent positions of adjustment on said bars or rods f f. To the said straight edge or surface of the said gage I detachably secure one or more lateral bearings or blocks D, having curved faces m, which are designed to bear upon a curved side or edge l of the work operated upon in the application of the plane structure to cut or form curved grooves in the surface of such work, substantially as is indicated at Fig. 1. The said bearings or blocks D may be constructed of wood, metal, or othersuitable material, as is apparent, and they may also be attached or secured to the gage in any suitable manner, screws o o being employed for that purpose in the present instance. Preferably I employ one of such bearings or blocks D at a point to one side of and in advance of the cutting edge d of the bit or plane-iron c and another at a point to the rear of such edge, and thus I may effectually operate the plane structure in the cutting or formation of grooves having either straight or curved sides or walls. It may be stated also that by continuing the curved side or edge l of the work in the formation of a complete circle the plane structure may be operated to cut or form circular grooves in the surface of such work, as is apparent, and it will be understood that by reversing the said plane structure and applying the curved bearings or blocks D to the opposite concave side or edge p of the work similar curved grooves may also be formed in the surface of the work in a like manner. In the use of this described embodiment of my invention for forming curved grooves from end to end of a piece of work, however, the foremost one of the said curved blocks or bearings D of the gage leaves the foremost end of the work before the cutting edge of the bit or plane-iron c has been carried forward far enough to complete the groove, and in the absence of the bearing afforded by said block against the work the entire plane structure is apt to twist or turn to one side or the other from the moving force applied thereto, and thus divert the cutting edge of the plane-iron from the true curvilinear path it is intended to follow. To obviate any such tendency, however, I prefer in most instances to employ substantially a similar block or bearing D2 intermediate the other two and at the same side of the plane-stock substantially coincident with the cutting edge d of the plane-iron, or slightly in advance thereof, and thus it will be seen that the true curvilinear path of the said cutting edge of the plane-iron is always maintained throughout the full extent of the grooves formed thereby. The said intermediate hearing or block D2 may not be constructed the same as the bearings or curved blocks D D; but preferably I construct the same in the present instance of a simple screw r, having a curved or rounded head S to bear against the curved side or edge of the work, said screw being adjustably inserted in a threaded opening therefor extending through the connecting member f2 between said blocks D D and the guide or gage C, as shown. On the outer end of said screw is a suitable jam-nut u for securing the same to the positions to which it may be adjusted. It will be understood that in some instances I may employ the said intermediate bearing D2 alone and dispense vrith the outer bearings or blocks D D for certain kinds of work — as, for instance, when cutting or forming curved grooves of exceedingly limited extent or dimensions from end to end. In most cases, however, I prefer the use or employment of said outer bearings or blocks on account of the stability afforded thereby in the operation of the plane structure, including, as the latter does, the gage and its appurtenances. I may also add that while I have herein illustrated my improvements as applied to a certain form of grooving plane and gage I am not limited to the use of these particular embodiments in the practice of my invention, as is apparent.

In virtue of the curved formation of the surfaces of the bearings or blocks D D when the plane structure is applied in a manner to have such blocks cobperate with the concaved side or edge of the work operated upon the whole plane structure is deflected inwardly in such manner as to keep the cutting edge of the plane-iron in the desired curvilinear path, all as hereinbefore mentioned, and it may also be said that substantially the same effect is had when the said bearings or blocks D D are applied to the convex side or edge of the work.

It should be explained at this point that if the cutting edge of the plane-iron should be made as wide as the predetermined width of groove to be formed in the work, then as a result of the deflection of the plane structure already explained the said cutting edge would tend to ride over the edges of the grooves, and thus mutilate said edges or destroy the angular symmetry thereof. To guard against any such destructive tendency, I construct the cutting edge of the plane-iron a little less in width than the intended width of the groove and I locate in advance of said cutting edge what I term “scoring” devices 2 2, which are arranged slightly to one side of or beyond the ends of the cutting edge d or at a distance apart substantially equal to the width of the groove to be formed. In this way the said scoring devices form parallel grooves in the work in advance of the main groove formed by the said cutting edge d, and thus is the latter enabled to properly conform to the predetermined curvilinear path therefor without in any manner injuring the edges of the grooves. As the plane structure is operated over the surface of the work, the bed of material remaining between the narrow parallel grooves formed by said scoring devices is successfully removed in an even manner by the slight shearing effect given to the cutting edge of the said plane-iron, as already mentioned.

I am not limited to the specific construction or organization of elements herein illustrated and described, and it is evident that it is immaterial at which side of the plane-stock the adjustable gage and its appurtenances are supported. It should be added as another reason therefor that the cutting edge d of the bit or plane-iron c is made less in length than the predetermined width of the curved groove to be formed in the work to enable the same to partake of the deflection of the plane structure without upturning or tearing away the edges of the groove, and it is also added that the scoring devices 2 2 in advance of said cutting edge d are each held to one side of the plane-stock by means of a screw 6, so as to enable said devices to be detached at any time for sharpening purposes or to be replaced by others.

In order to enable the cutting or formation of short curved grooves to be edected by the use of my improvements, more especially when the lateral bearing-blocks are made to ride a concaved or inner curved side or surface of the work operated upon, I make said bearing-blocks adjustable to be moved toward each other and secured in position, and while any suitable means may be employed for this purpose I have herein indicated a simple construction therefor at Fig. 4. Thus in said Fig. 4 I construct the straight portion or surface h2 of the gage C with two oblong openings or slots 8 8, passing through which are tightening or fastening screws 9 9, which enter the lateral bearings or blocks D3 D3. It is evident that by loosening said screws they and the said bearings or blocks may be adjusted along said straight portion or surface h2, after which the screws may be again tightened to secure the blocks in place.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to improvements in planes, and more particularly to that style of plane known as a “dado-plane,” and has for its object to provide adjustable means for limiting the depth to which the cutting of the plane may proceed.

A further object is to provide a plane of this character with a supplemental sole cooperative with the sole and which is easily and quickly adjustable and which can be securely maintained in its adjusted position.

A further object of my invention is to provide adjusting means which will also cooperate with the securing means for the purpose of maintaining the sole in its adjusted position.

In the drawings accompanying and forming part of this specincation is shown my invention applied to a form of dado-plane, which may be the preferred form, if desired.

Figure 1 is an elevation of a plane having my invention applied thereto. Fig. 2 is a plan view of the forward end of the plane, showing the same on a somewhat larger scale. Fig. 3 is a cross-section on the line 3 3, Fig. 2. Fig. 4 is a form of adjusting-screw, and Fig. 5 is a form of supplemental sole or guide.

Like characters of reference designate the same parts in the various figures, wherein a plane-stock is represented generally by 6, having a sole 7, through which works a suitable plane-iron 8 and in connection with which are adjustable guide-knives 9 9. To the plane-stock is iitted a supplemental sole 10, having a projecting slotted arm 11, ways or guides 12 and 13, and a tapped boss 14. The supplemental sole is adapted to be secured to the plane-stock, generally at one side of the stock and forward of the mouth, by means of a set-screw 15 traversing the slotted arm and tapped hole in the plane-stock. The way 13 is shown as being of greater projection than the way 12, and it is adapted to enter and slide in a groove or guide 16 in the plane-stock; to prevent lateral movement or oscillation of the supplemental sole, the other way 12 being adapted to slide upon a face provided for it on the side wall of the plane-stock. The way 13 is shown in the drawings as having square corners and a fiat face, although any other or convenient form of way may be employed. The plane-stock is provided with a tapped boss located above the tapped boss in the supplemental sole. These bosses are adapted to be traversed by an adjusting-screw 17, preferably made with right and left threads of differential pitch. This screw is adapted for raising and lowering the supplemental sole, and it cooperates with the set-screw for maintaining the supplemental sole in its adjusted position.

It will be readily seen that by loosening the set-screw the supplemental sole may be raised and lowered at will by means of the screw 17. If the adjusting-screw is made with the portion traversing the boss in the stock of a greater number of threads to the inch than the part of the screw which traverses the boss in the supplemental sole, the head of the adjusting-screw will not have to be raised as great a distance as if both screw-threads were provided with the same number of threads, and hence I preferably employ such an embodiment herein. With such an organization increased range of adjustments of the supplemental sole may be affected by a very slight turn imparted to said screw. It will be observed that the said right and left hand differential adjusting-screw 17 is also of different diameters in its length, the portion thereof having the least number of threads being less in thickness or diameter than the portion having the greatest number of threads thereon, such construction permitting the insertion or passage of the said adjusting-screw through the tapped opening in the boss of the stock, it being evident that if the screw was of the same diameter throughout it could not be passed through such opening on account of its differential character and the right and left hand directions of its threads, the said tapped opening in the boss referred to being only adapted to receive that portion of the screw of the greatest diameter and greatest number of threads per inch ratio.

By the organization of the parts that is contemplated in my invention a screw of the general construction described, after adjustment of the supplemental sole, will not be readily jarred out of place, and it will cooperate with the ways and the set-screws for maintaining the parts in their adjusted position, so that although the supplemental sole has but one adjusting device and but one retaining device per se it has two maintaining devices aside from the ways, rendering all pivotal action impossible, so that the greatest accuracy of adjustment is possible with this plane, which in fine work it is essential should be had. Otherwise the tool would not do neat and accurate work.

It will thus be seen that the differential thumb-screw 17 may be assembled by passing its small-diameter coarsely-threaded tip end through the large hole in the stock and then engaging said tip with the small threaded hole in the lug 14 upon the supplemental sole and also engaging the finely-threaded large-diameter upper end of the screw with the hole in the stock. Then the transverse clamping-screw 15 is inserted through the vertical slot in the supplemental sole, the shank of said clamping-screw thereupon serving to limit the vertical adjustment of the supplemental sole, so that the thumb-screw 17 cannot be withdrawn from the latter, this being a desideratum, since it is required in this class of tools that when once assembled for use no operation such as is necessary for its adjustment shall be capable of taking the tool apart. In practice the upper end of the screw 17 is provided with right-hand thread and the lower end with left-hand thread, as illustrated.

It will be observed that I avoid slotting or forking, and hence weakening the stock, as is usual where adjusting-screws are used having double collars, and I also avoid the expense of applying a collar to a screw after the insertion thereof in the stock, as well as the consequent additional complexity of construction and looseness of parts, such small pieces becoming loosened quickly and seriously impairing the usefulness of the plane, rendering the same of a ramshackle character. By my invention an ease and accuracy of adjustment are secured which are not found in planes having ordinary screws and collars and other loose parts. The integrality of construction of the screw and the absence of small accessories thereto gives firmness of feeling to the action of the slide, so that the workman can tell exactly what he is doing. All this is accomplished without a single piece of any kind being added to the mechanism, thus securing a minimum of both weight and expense. The adjustment is reduced absolutely to the fewest elements. No smaller number of elements can be employed, and, moreover, no greater advantages can be obtained from the use of a greater number of parts. Thus is satisfied the imperative requirements in this art — of lightness, rigidity, simplicity, inexpensiveness, durability, and delicacy of action.

Although I have shown a set-screw and a right and left differential screw, yet any other or convenient mechanical devices which in practice may be found desirable may be employed without departing from the spirit of my invention.

Having described my invention, I claim —

1. In a plane, the combination with a stock having a sole, of a supplemental sole, a threaded hole in the stock, a differently-threaded hole of different diameter in the sole, and a single thumb-screw having correspondingly-threaded shanks of large and small diameters working in both of said holes.

To all whom it may concern:

Be it known that we, ALIX NV. STANLEY and HENRY S.WALTER, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

Our invention relates to improvements in the construction of planes.

The object of our invention is to provide a simple, inexpensive, and effective means for securing in place the means whereby the position of the cap of the plane is determined, as will he understood from the following description, taken in connection with the accompanying drawing.

In the illustration we have shown a side elevation of a plane fitted with an embodiment of our improved construction, parts of the plane being seen in section.

The plane which we have chosen to here describe is an iron plane, in which A is the bottom.

B is what is commonly termed the “frog” of the plane. This frog B is secured to the base and presents an inclined upper surface leading down to the slot in the base A, through which the plane-iron C projects. In this type C’ is a plane-iron cap, the two parts thus forming a double plane-iron. The iron C furnishes the cutting edge.

D is what is termed the “cap.” In the particular construction shown this cap is provided with a cam D’.

E is what is termed the “cap-screw” or “holder.” This part E is ordinarily in the form of a headed screw, which takes into a tapped hole in the frog B. This holder E is seldom if ever adjusted after it has been secured in its proper position, and it is desirable to have it snugly retained in that position, so that it will not work loose and disturb the adjustment or allow chattering of the parts when in use. At the same time it is desirable not to have a permanent connection in order that in the event of an emergency a new holder can be inserted. In case the cap should become broken or lost a new cap must be inserted, and if it should vary slightly in dimensions from the original cap the holder must be adjusted. It will therefore be seen that an adjustable cap-screw that will not become loose or accidentally disturbed from its proper position is the end which we seek to attain.

F is a lever or Y adjustment pivoted to the frog B, one end of which is adapted to engage with the plane-iron C, the other end being engaged by an adjusting-nut G. This nut or thumb-nut G is movable on a screw or post H, also carried by the frog B. The plane-iron may be advanced or retracted relatively to the bottom of the plane by means of the adjusting-nut G, which operates the lever F, engaging with the plane-iron, regulating the depth of the cutting edge in the usual manner.

Our invention will be found to consist in so arranging the screw-threaded or tapped passages in the frog B for the cap-screw E and the post H that the said passages intersect for the purpose of permitting the post H to be set up against the holder or cap-screw E when the latter is in its proper position.

We thus securely lock the parts in place to prevent their becoming accidentally displaced or loosened. The screw or post H therefore performs a double function. Not only is it a means for supporting the thumb-nut G for the adjustment of the plane-iron, but it also forms the locking means for the cap-screw or holder. In our preferred construction the thread of the screw E, adjacent the point where the end of the screw H is to engage and lock the same, is turned down, so as to remove the screw-threads. Consequently the end of the screw H will not batter the screw E and render it difficult or impossible to operate it when desired. Furthermore, by so doing a better bearing-face is afforded for the end of the locking screw or post H. Heretofore the frictional engagement of the screw-threads of the cap-screw E has been solely relied upon as the means for holding the screw in position.

By our improvement a simple, inexpensive, and effective means is provided whereby if the frictional engagement of the screw-threads is insufficient the movement of the cap~screw is nevertheless prevented.

The assembling of the plane is accomplished in the well-known manner, there being nothing to require special instructions in regard thereto. The plane-iron is inserted in the usual way, and the cap D is placed thereon, a keyhole-opening D2 in the cap allowing the cap to be slipped on over the holder E. It is then slid down into place, so that the head of the screw or holder E will stand over and engage the cap D. The cam D’ is then swung down into the position shown, and thus securely clamps the parts together. Should the cap-screw E become loose, the plane-iron or parts associated therewith will be likely to chatter, producing unevenness and other undesirable results in the work performed. This is entirely avoided by the employment of our invention.

It should be obvious that the improvements in the construction herein set forth are applicable to many different styles of planes, wood as well as iron, and that the bearing for the plane-iron instead of being a separate frog might be made an integral part of the plane itself, also that the particular form and arrangement are not material so long as the combination of cap-screw and post H is such that the latter element performs the double function of supporting the thumb-nut G and securing the cap-screw effectively in place.

What we claim, and desire to secure by Letters Patent, is —

1. In a plane, a plane-iron, a bearing therefor, a cap-screw for holding said plane-iron in engagement with said bearing, an adjusting-screw for regulating the position of said plane-iron, said adjusting-screw also engaging said cap-screw to lock it, substantially as described.

2. In a plane, a plane-iron, a cap-screw for holding said plane-iron in position, an adjusting-nut, a screw therefor, said screw engaging said cap-screw, substantially as described.

3. In a plane, a plane-iron, a cap-screw for holding said plane-iron in position, a portion of the thread on said cap-screw being turned down, a separate screw engaging the turned-down portion of said cap-screw, and an adjusting-nut mounted upon said separate screw, and means coacting with said adjusting-nut for shifting the position of the plane-iron without disturbing the adjustment of the cap-screw.

4. In a plane, a holding-screw E set into the frog B, an adjusting-nut working on a screw H, said screw engaging said holder to lock it in position, substantially as described.

To all whom it may concern:

Beit known that I, HENRY RICHARDS, a citizen of the United States, residing at Pine Meadow, in the town of New Hartford, in the county of Litchfield and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates principally to the manner of seating frogs upon the stocks of bench-planes. Stocks are generally cast with wide and broad thick seats, thus making a large mass of metal at one portion of a thin casting, which engenders trouble both in casting the stock and subsequently in finishing the same. In casting the thin plates forming the sole and sides of the stock cool, while the thick mass forming the seat is still hot, so that as the latter subsequently cools stresses are set up, which are liable to cause flaws in the castings. In finishing these stresses become manifest when the bottom surface of the sole is faced off by throwing the surface out of alinement, making an extra finishing operation necessary. Moreover, finishing a broad surface for the frog-seat often throws the stock out of true, necessitating a further cut to be taken upon the bottom surface thereof. Metal planes are peculiarly sensitive to the action of such stresses, since the sole and flanges thereof are necessarily made thin in order to minimize the weight, and hence warp from very slight causes. Moreover, the weight of a broad and wide solid seat for the frog, with which the stock is usually provided, is a source of objection. For this reason it is impracticable to form threaded holes of requisite depth for properly receiving the vertical frog-clamping screws, so that stripping of the threads is liable to occur and the screws do not reliably clamp the frog upon its seat. Moreover, said seats have not sufficient thickness to properly accommodate a fore-and-aft frog-adjusting screw. Many of these defects are due to the necessity of lowering the seat of the frog as far as possible, so that the seat may extend close to the throat, thus making the unsupported fore part of the frog of minimum length to avoid chattering. It is principally for this reason that said seat cannot in good practice be of such height as to have a substantial bracing effect upon the stock, so that the latter is very liable to warp, even being distorted in some cases by the mere tightening of the frog-clamping screws. Again, planes as heretofore constructed have been more or less liable to chatter, this fault being-attributed to the upward pressure or reaction of the wood against the edge of the blade, whereby the fore part of the frog is sprung, thus setting up a vibration. This is particularly the case when the wood is hard and resistinge — as, for instance, in facing rose-wood across the end of the grain. Owing to this defect the range of work which can be performed by a plane of the usual structure is seriously reduced, so that it is necessary in most cases when facing across the end of the grain to employ a different type of a plane specially fitted for the work.

This invention aims to improve the operation of the plane and increase its range of usefulness and also to enable high-class planes to be produced at low cost by overcoming various difficulties in their manufacture. I greatly reduce the stresses which are set up by the cooling of the stock in casting, so as to prevent flaws and also minimize the liability of the stock warping at the finishing operations, and I restrict such stresses to a limited portion of the plane considered lengthwise, thus avoiding the usual depressions or hollows in the stock, due to shrinkage. I reduce the surface forming the main seat for the frog, so that the finishing thereof may not warp the stock, and distribute the metal in such a manner that the stock is substantially stiffened without adding to its weight unduly, if at all. I make provision for threaded holes of ample depth and capacity and seat the frog so firmly upon the stock as not only to prevent chattering, but also to greatly improve the effectiveness of the plane and increase its range of efficiency and to steady the fore part of the frog at the point where the plane-iron is clamped thereon, while permitting ample adjustment for closing or opening the throat, and also prevent chattering of the plane, due to the springing of the frog, by either the downward drag or the upward resistance of the wood. In general I furnish a construction adapted to meet all of the numerous and peculiar requirements necessary in practice for satisfactory results in planes of this class, and especially when employed upon highly-resistant woods and when set for the production of fine surfaces, in which cases any flexibility or chattering is particularly objectionable.

A further object of my invention is to overcome a fault in the cam usually employed to clamp the plane-irons upon the frog, whereby the pressure at the lower portion of the blade is relieved and chips are permitted to crowd up between the blade and the cap-plate thereon.

In the drawings accompanying and forming part of this specification, Figure 1 is a side elevation, partly in section, of a plane made in accordance with my improvements. Fig. 2 is a cross-section taken on the line x x of Fig. 3 and showing an adjustable frog from the rear. Fig. 3 is an enlarged sectional elevation of the frog and parts adjacent thereto shown at Fig. 1, this section being taken on the median line of the plane. Fig. 4 is a section similar to Fig. 3, but taken on the line y y of Fig. 2. Fig. 5 is a plan of the middle section of my improved plane-stock and showing also a frog-adjusting screw. Fig. 6 is a fragmentary view similar to Fig. 4, but showing the frog as adjusted forwardly so as to nearly close the throat.

In the several views similar parts are designated by similar numerals of reference.

The plane-stock may consist of a thin floor or sole 1, finished upon its bottom surface, and thin side flanges 2, connected forwardly of the throat 3 by means of a thin high stiffening-rib 4. The stock may also be provided with the usual back handle 5 and front knob 6. At a point well in rear of the throat I join the flanges 2 by a high rib 7, which may be rather thin in cross-section, and trusses the side flanges, producing a stilf box-like device. The top edge of the rib is faced off at 7a in parallelism with the bottom or working surface of the stock. Upon the forward side of the rib 7 I provide bosses 8, one at each side of the median line of the plane, in which I form threaded vertical holes 9 for the reception of screws 10, which clamp a frog 11 upon the stock. At a point between the bosses 8 I form in the rib 7 a threaded horizontal perforation 12 for the reception of a screw 13, whereby the frog may be adjusted forward and back, so as to close or open the throat 3. Along the rear edge of the throat I thicken the sole and finish its upper surface at 14 in parallelism with the top 7a of the rib 7, so that the surfaces 14 and 7a may cooperate to form a chair for the frog. The thickened portion at 14 braces the comparatively weak sole of the plane at this point, but is very much depressed below the surface 7a, so that said surfaces form steps, which are separated, so as to give a broad bearing for the frog.

The frog consists of the body portion 11 and a forwardly-sloping bed 15, the lower part of the latter at 15a projecting downwardly and forwardly from the body portion. At its lower edge said projecting part is fitted upon the step 14, so that the frog may be adjusted forward and back in parallelism with the working face of the plane and be always firmly seated upon the chair. As will be observed at Fig. 4, the frog is provided with slots 16 for the binding-screws 10, permitting the adjustment of the frog, which may be effected by means of the fore-and-aft screw 13, whose grooved head engages a slotted ear 17, secured to the frog by a screw 18.

A blade 19 lies upon the bed 15 and projects beyond the lower edge thereof into the throat 3. This blade may be of the usual construction and is provided with a customary cap-plate 20. The usual longitudinal and transverse adjustments may be effected by means of a screw-operated yoke-lever 21 and a swinging lever 22. The plate-irons 10 and 20 are releasably secured upon the bed by means of a clamping-bow 23, which bears at its lower end upon the cap-plate 20 and at its upper end is provided with an improved cam-lever 24 and works upon the head of a screw 25, projecting from the frog.

It will be observed that by dividing the chair into two well-separated portions abroad seat is obtained for the frog without unduly weighting the plane. The forward step 14 steadies the frog, and hence the blade, at a point close at the working surface of the plane, the plane being adjustable for different kinds of work without detracting from the steadiness of the frog at this point. The high truss 7 renders the stock especially rigid at the very point where the distortive stresses are produced by the clamping-screws, so that the frog may be securely clamped upon its broad chair without warping the thin plane-stock.

The feature of adequately supporting the fore part of the frog when it is adjusted forwardly for different classes of work, as at Fig. 6, is of great importance in my improved plane, since the blade is always given a firm bearing at a point very close to its cutting edge. My improvement is of great value when the plane is used upon highly-resistant woods and when set for the production of line surfaces, in which case any flexibility of the knife is particularly objectionable, producing chattering and making it difiicult or impossible to produce the desired finish. It will also be seen that by dividing the chair into two steps and placing one thereof close to the edge of the throat, so as to afford a positive support for the lower edge of the frog, I am able to heighten the rear step materially, and I thus not only materially stiffen the thin plane-stock, but apply the stiffening-truss at the very portion which is subjected to the most stress. Moreover, I am enabled to increase the depth of the holes for the clamping-screws and also to make ample provision for a fore-and-aft adjusiing-screw and all without adding materially to the weight, but instead reducing the objectionable thickness of metal usual in stock of this kind.

A further and important feature of my improvements appertains to the means illustrated for putting the fore part or nose of the frog normally under tension, whereby I am enabled to secure a perfect action of the plane. As will be observed at Fig. 4, the clamping-screws 10 bear upon the frog at a point between the two steps of the chair, thereby not only clamping the body of the frog securely upon the rear step, but also tending to flex the fore part of the frog and holding it down upon the seat 14 with considerable pressure. Owing to this normal tension upon the frog, it results that applying pressure to or removing it from the blade when planing operates in a far less degree than heretofore to spring the frog. It will be understood that when a frog is held upon a broad single seat by means of screws located in the usual manner this normal stress or tension of the frog is wanting, and the fore part of the frog consequently is left somewhat flexible, so that the pressure of the wood upward under the point of the blade springs up both the blade and the frog and permits a vibration which in many cases amounts to a chattering of the edge of the blade upon the wood. Thus it will be seen that I not only provide a positive support at all times for the fore part of the frog, but also that I spring said fore part upon said support, so that the blade is prevented from chattering either by the downward pull or by the upward thrust of the wood. I thus widen the range of work for which this type of plane is adapted and secure a more reliable operation and better results generally on all kinds of work.

Owing to the proximity of the clamping-screws to the rear-step 7a and their remoteness from the forward step 14, the pressure upon the frog is distributed between the two steps in substantial correspondence to the relative abilities of the two portions of the thin stock to sustain the pressure, without warping or distortion, so that the frog is thus put into condition to avoid chattering without incurring a liability of distorting the stock.

The cam-lever 24 is formed with a curved working surface 24a, which as the lever is turned gradually forces the bow against the plane-irons, said surface 24a terminating in a tangential stop-surface 24b, which arrests the lever just as the point of greatest compression is reached, so that there is no possibility of a reactional movement of the plane-irons, as is usually the case, and the latter are held under maximum tension, thus im-
proving their action and avoiding the liability of chips working between the irons.

Not the least of the several valuable features of my invention consists in the provision for adjustment of the frog forth and back in substantial parallelism with the nnished bottom or working surface of the stock and at the same time enabling said frog however adjusted to be firmly supported not only at its main or body portion, but also at its front end. At least one and preferably both of the elements 15a and 14 are finished in substantial parallelism with the working surface of the stock, and the same is true of the elements 7 and 11. In the construction illustrated a parallelism of adjustment is secured through a parallelism of bearing-surfaces with the working or bottom face of the stock, one of said parallel bearing-surfaces being in front and being formed or provided upon either the frog or the stock, and another of said parallel bearing-surfaces being in rear and also formed or provided upon either the frog or the stock, the surfaces contacting with said parallel bearing-surfaces being themselves preferably also parallel with said working face of the stock, thereby giving considerable breadth or area of contact at both the fore and aft portions of the frog, which is desirable. It will be understood that by having at least one such parallel bearing-surface in front and at the lower portion of the plane and at least one more such parallel bearing-surface in rear and at a considerable elevation it becomes practicable both to adjust the frog forth and back and also to support the same firmly both fore and aft at all such adjustments. I consider it of especial value that the portion 7 of the stock has a stepwise arrangement relatively to the bearing-surface at the throat in said stock, since thereby it becomes practicable in this class of planes to effect a parallel adjustment of the frog while always firmly supporting not only the body but also the fore foot of the latter, this fore foot being an exceedingly sensitive part of the plane and the true action thereof being of the utmost importance. It will be observed that the frog at its forward end affords a direct support for the lower ends of the plane-irons and also at said end and close to the lower ends of said plane-irons bears directly upon the sole of the stock at all times. By maintaining the frog constantly at the same vertical distance from the working-surface or floor of the stock the throat may be closed or opened to any extent by a simple and rapid manipulation without the necessity of resetting the plane-irons either in longitudinal direction or transversely by means of the lever 22, while at all times the action of the plane is rendered most satisfactory. In this instance the adjustment of the frog is effected by means of a fore-and-aft screw threaded into the material of the stock beneath the base of the frog and connected to the latter.

Variations may be resorted to within the scope of my invention, and portions of my improvements may be used without others.

_________________

To all whom it may concern:

Be it known that we, SOLON R. RUST and ARTHUR E. RUST, of Pine Meadow, in the county of Litchfield and State of Connecticut, have invented a new and useful lmprovement in Planes; and we do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in —

Figure 1, a view in side elevation of a plane constructed in accordance with our invention; Fig. 1a, a view thereof in transverse section on the line a b of the preceding figure; Fig. 2, a view of the plane in vertical central longitudinal section; Fig. 3, a plan view of the body of the plane stripped of all other parts; Fig. 4, a reverse plan view thereof; Fig. 5, a plan view of the removable sectional wooden face, the sections of which are separated from each other; Fig. 6, a view in transverse section on the line c d of Fig. 5; Fig. 7, a plan view of the removable sectional metal face of the plane with the sections drawn apart; Fig. 8, a view in transverse section on the line e f of the preceding figure.

Our invention relates to an improvement in that class of bench-planes designed for smoothing as distinguished from beading or rabbeting, and more particularly to smoothing-planes having metal bodies, the object being to produce at a low cost for manufacture a simple and strong plane constructed with particular reference to its adaptation to have a metal or a wooden face applied to it interchangeably, so as to readily adapt it to be used in situations requiring wooden faces as well as in situations requiring metal faces.

With these ends in view our invention consists in a plane having certain details of construction and combinations of parts, as will be hereinafter described,and particularly recited in the claims.

In carrying out our invention as herein shown the metal body A of the plane has cast integral with it an inclined cutter-supporting bed B, the opposite edges of which are supported or trussed by longitudinal flanges A’, rising from the opposite edges of I the upper face of the body. As shown, these flanges extend throughout the length of the body for increasing the strength thereof; but this is not essential. These flanges A’, as shown, are raised at points opposite the bed B, but elsewhere are straight and uniform in height. The said bed is provided for supporting the cutter, (not shown,) which may be of the usual construction and which is secured in place and adjusted in any desired manner. For the purpose of casting the said integral cutter-supporting bed without the use of cores a large casting-opening A2, which is located directly below the bed, is formed. This opening performs no function in the completed plane, but, as aforesaid, permits the body A to be cast without the use of a core, whereby the expense of producing the plane is greatly reduced. The body. A is also formed with a throat-opening A2, located directly in front of the casting-opening aforesaid and permitting the shavings removed by the cutter to escape upward through the plane.

To adapt the plane to be used in situations requiring wooden as well as metal faces, we design to provide each plane-body with interchangeable faces made of wood and of metal, respectively, these faces being constructed to correspond in size to the lower face of the body, so as to completely cover the casting-opening A2, formed therein.
These removable faces of wood and metal may be formed in one piece or in sections, as desired. As an illustration of their construction we have shown a sectional wooden face composed of a long rear section C and a short forward section C’. The said wooden section C is secured in place by screws D passing downward into it through the body of the plane, which for that purpose is formed with screw-holes D’, while the forward section is adjustably secured in place by means of a handle E, having a threaded stud F passing downward through an elongated slot G, formed in the forward portion of the body. The stud F is entered into the said forward section C’, which by turning the handle E is clamped against the forward end of the lower face of the body, so as to be held firmly in place; but as the adjacent ends of the two sections wear so as to unduly increase the opening H, Fig. 2, between them below the throat-opening A3 the forward section is moved rearwardly, so as to take up this wear by loosening the handle E.

As shown in Fig. 1a of the drawings, the lower face of the body is provided with two parallel centering-flanges I I, the inner faces of which are beveled and which insure the centering of the removable face when it is applied to the body; but these flanges are not necessarily employed, although we prefer to use them. To coact with the beveled inner faces of the flanges I I, the upper corners of the sections C and C’ are beveled, as shown at c in Figs. 1a and 6. When the removable face is made in sections, we preferably form the forward sections with two rearwardly-extending fingers J J, Fig. 5, which extend across the ends of the throat-opening A3, so as to prevent the shavings from clogging.

The removable metal face of the plane shown in Figs. 7 and 8 of the drawings comprises a long rear section K and a short forward section K These sections are reinforced and strengthened by the formation upon their upper faces of longitudinal side ribs L L and a longitudinal central rib L’. The rib L’ is enlarged near its ends to form posts L2 L2, which are internally threaded for the reception of the screws which hold it in place by passing down through the body of the plane, while the rib L’ of the forward section K is formed with a corresponding post L3 for the reception of the threaded stud F of the handle E. As shown in Fig. 8, the upper outer corners of the side ribs L of the sections K K’ are beveled, as at k, for coaction with the beveled inner faces of the centering-flanges I of the body of the plane.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is —

1. In a bench-plane, the combination with a metal body having an integral cutter-supporting bed both edges of which are supported or trussed by the body which is formed with a casting-opening located directly beneath the said bed, of a removable face adapted to be applied to the lower face of the said body to which it corresponds, and extending entirely over the said casting-opening.

2. In a bench-plane, the combination with a metal body having an integral cutter-supporting bed, both edges of which are supported or trussed by the body which is formed with a casting-opening located directly beneath the said bed, of a removable sectional face adapted to be applied to the lower face of the said body to which it corresponds in size, and extending entirely over the said casting-opening.

3. In a bench-plane, the combination with a metal body having an integral cutter-supporting bed both edges of which are supported or trussed by the body which is formed with a casting-opening located directly beneath the said bed, and with a throat-opening located in front of the said casting-opening, of a removable sectional face adapted to be applied to the lower face of the body so as to entirely cover the said casting-opening, and comprising a forward section which is longitudinally adjustable for taking up wear at the said throat-opening.

4. In a bench-plane, the combination with a metal body having an integral cutter-supporting bed both edges of which are supported or trussed by the body which is formed with a casting-opening located directly beneath the bed, of removable interchangeable metal and wooden faces adapted to be applied to the lower face of the body to which they correspond in size and the said casting-opening in which they entirely close.

5. In a bench-plane, the combination with a metal body having an integral cutter-supporting bed both edges of which are supported or trussed by the body which is formed with a casting-opening located directly beneath the bed and with a throat-opening located in front of the said casting-opening, of a removable sectional face adapted to be applied to the lower face of the body to which it corresponds in size, and the said casting-opening in which it entirely closes, the forward section of the said face being made longitudinally adjustable for taking up wear at the said throat-opening, and formed at its rear end with rearwardly~extending lugs which extend across the said throat-opening.

In testimony whereof we have signed this specification in the presence of two subscribing witnesses.

Be it known that I, ALBERT F. SCHADE, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Carpenters’ Routers, of which the following is a specification.

My invention relates to improvements in carpenters’ routers; and the object of my improvement is to provide simple and efficient means for adjusting the cutter.

In the accompanying drawings, Figure 1 is a plan view of my router; and Fig. 2 is a sectional side elevation, the bed plate or frame being in vertical section on the line x x of Fig. 1.

The bed plate or frame A, tool-post 3, yoke 4, and set-screw 5 are of an ordinary and well-known construction. The cutter 6 is also of an old form, excepting as I provide a recess or notch 7 in its rear side near its upper end. In the center of the tool-post 3 and projecting upwardly therefrom is the adjusting-screw 8, rigidly and permanently affixed thereto or formed thereon, so as to constitute an immovable part thereof. Upon this screw is the adjusting-nut 9, preferably having a roughened or knurled edge for convenience of manipulation. This nut is of a diameter so large as to project into the path of the upper end of the cutter 6, whereby the adjusting-nut 9 and the cutter 6 may be assembled with the edge of the nut projecting into the recess or notch 7 in the cutter 6, as best shown in Fig. 2.

It will be readily seen that the cutter may be adjusted either up or down by turning the adjusting-nut 9; also, that the parts may be assembled when desired with the adjusting-nut above the notch in the cutter or wholly removed, so that the cutter may be used without any adjusting mechanism. The cutter 6 may also be placed in the reverse position on the back side of the post, as indicated by broken lines in Fig. 2, and the same adjusting mechanism is adapted for use with the cutter in this reversed position. The construction is simple and inexpensive, and the improved device is very convenient for effecting a fine adjustment, while it in no way interferes with any of the ordinary uses of the router.

I claim as my invention —

The combination of the bed-plate, the double-faced tool-post, projecting upwardly above the said bed, the cutter fitted to slide vertically cn the sides of the said tool-post, means for confining the said cutter in place on the said tool-post, the adjusting-screw 8, centrally mounted in the upper end of the said tool-post and projecting upwardly therefrom, and the adjusting-nut 9, mounted on the said adjusting-screw and operatively connected with the upper end of the said cutter, whereby the said adjusting mechanism may be used when the cutter is placed on either side of the said tool-post, substantially as described.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Fence-Supports for Carpenters’ Plows, &c., of which the following is a specification.

My invention relates to improvements in fence-supports for carpenters’ plows, beading and molding tools, etc.; and the object of my improvement is to furnish a support for the fence to assist the user in holding the tool in proper position relatively to the surface of the work.

In the accompanying drawings, Figure 1 is a plan view of a combination beading and molding tool, plow, &c., with my fence-support applied thereto. Fig. 2 is an end view of the same; and Fig. 3 is a sectional side elevation of a portion of the same, the plane of section being indicated by the line x x, Fig. 1.

A designates the stock or main portion of the tool, having two laterally projecting fence-rods 4 4, upon which the fence 5 is supported and adjustably held in position thereon by means of the set-screws 6. The said stock also has secured therein the beading-tool 7. These parts are all old and well known, and therefore any further description thereof is deemed unnecessary. It is also apparent that the detail construction of the minor parts is immaterial to the present invention, and any other known tool-stock having laterally-extended fence-rods and a fence supported thereon may be substituted as a known equivalent for the said stock and its minor parts.

An expert workman by proper effort can and does keep the tool in such a position when working that the fence-rods will be parallel to the surface of the wood operated upon; but in order to enable him to do so with greater ease than heretofore and also to better enable one of less skill in use of the tool to hold the tool in proper level position I employ the fence-support 8. Although I have in accordance with the usual phrase entitled my invention as an “Improvement in fence-supports for plows, &c.,” I do not thereby wish to imply that a fence-support of any kind for such tools was ever before known or used.

The preferred form of my fence-support is that of a cam or snail-shaped device having a perforated hub or socket 9 of a size to fit one of the fence-rods 4, preferably the forward one, so that it may swing or partially turn thereon to vary the height of its under face relatively to the fence and also that it may slide on the said rod for changing its position laterally whenever the fence is adjusted laterally on the said rod. I provide the said hub or socket 9 with a set-screw 10 for holding the support in the desired adjusted position.

The operator may set the support at first so as to bring its lowest and gaging face as much above the lower end of the beading or cutting tool as the depth of the cut to be made, and thus insure the proper position of the tool at the nnish of the beading or other work, or he may first set the support with its lower edge at about the same height as the end of the tool and then change the support by adjusting its face downwardly as the work progresses. In case the support is not wanted it can readily be wholly removed, leaving the tool in its original position.

While the snail or cam form of support herein shown is the preferred one as the most convenient construction for perfecting the desired adjustments, this particular form is not always necessary, as it is only essential that the device, whatever it may be, shall be capable of lateral adjustment on the fence-rods and also of vertical adjustment of its supporting-face relatively to the said rod.

I claim as my invention —

The herein-described fence-support for carpenters’ tools of the class employing fence-rods and a fence, the said support consisting of a cam-shaped device having a socketed hub fitted to one of the fence-rods, substantially as described.

This invention relates to spokeshaves, and has for one object the provision of an improved tool which may be employed on various varieties of wood with good results and one in which the knife and the guard or throat-gage are adjustable in planes at right angles to each other; the back of the guard being formed with a plane face constituting a wall of the throat for the reception of the shavings, whereby the straight edge of said guard opposed to the knife may when injured or blunted be readily renewed by simply grinding said face.

A further object of the invention is the provision within the stock of the spokeshave of a chamber for the reception of shavings, the upper wall of said chamber being curved outwardly to facilitate the discharge of said shavings.

A further object of the invention is the provision, in connection with a spokeshave, of a guard or throat-gage, the working surface of which is convex both transversely and longitudinally.

In the accompanying drawings, Figure 1 is a plan view of my improved spokeshave, part of one of the handles being broken away. Fig. 2 is a side elevation, partially in section. Figs. 3 and 3a are transverse sections on line into of Figs. 1 and 2, showing different adjustments of the guard or throat-gage. Fig. 4 is a perspective view of the knife or cutter. Fig. 5 is a perspective view of the guard, and Fig. 6 is a perspective view of one of the bolts for adjustably securing the knife in position.

Similar characters designate corresponding parts throughout the several views.

Referring to the drawings, the numeral 5 designates the stock of my improved spoke-shave, having the usual handles 5′ 52 and provided with a chamber 6 (the wall 6′ of which is curved outward for a purpose hereinafter described) and with a forward straight portion 62.

Formed in the stock at each end of the chamber 6 are grooves 7, having rabbeted portions 7′, constituting guideways for the reception of flanges 8 on the ends of a knife or cutter 9, which is preferably of the “razor-blade” type and is slightly curved longitudinally, and fitted in said grooves 7 are the flat oblong heads 10′ of bolts 10, the threaded shanks of which pass through perforations in the stock and carry thumb-nuts 12, by turning which the heads 10′ may either be forced tightly against the flanges 8 of the cutter or released therefrom to permit said cutter to be adjusted, as desired. Cooperating with this cutter is a guard or throat-gage 13, slotted at 13′ for the reception of screws 14, which enter the stock, in virtue of which construction the guard may be adjusted transversely of the cutter to vary the dimensions of the throat in which the shavings enter between said parts.
It will be observed by reference to Figs. 3 and 3a that this guard is provided with a plane back 132, which terminates in a straight edge 133, and when this straight edge is blunted or otherwise injured by wear, as frequently happens, it can readily be restored by removing the guard and grinding the flat face 132, after which it can be replaced with said face in engagement with the corresponding flat face 62 of the stock. On its lower or grinding surface the guard is made convex both longitudinally and transversely, as at 15, and can therefore much more readily be applied to rounded surfaces of the work. The face 15, which extends outward from the edge 133, is joined to the back 132 by the curved surface, which at its upper portion becomes nearly or quite parallel to the back, forming a body of convenient thickness in which to locate the slots 13′.

By reference to Figs. 3 and 3a it will be seen that the knife 9 and guard 13 may be so adjusted with relation to each other that the cutting edge of the knife will be brought into line with and almost touch the straight edge of the guard, whereby a very fine shaving may be removed from the work, if desired.
This is especially important when cutting hard wood or across the grain and obviates to a large extent the danger of splitting the wood or of tearing out a splinter therefrom — accidents of frequent occurrence with the old styles of spokeshaves, in which the knife overlaps a beveled edge on the guard.

As is well known, chips or shavings entering the mouth between the guard and knife tend to curl or assume a helical form, and to aid them in this action they are caused to impinge against the curved wall 6’ of the chamber 6 and are by said wall guided and defiected toward the exterior of the stock.

By my improved construction it will be seen that the guard may be so adjusted that the edge of the knife may be brought into line with the straight edge 133 or caused slightly to overlap the same, if desired, thereby enabling the tool to be employed on various kinds of woods, either hard or soft, at pleasure, for, as is obvious, the height of the knife above the guide-surface and also the position of the cutting edge may be regulated with nicety to obtain a throat of the desired width.

As will be observed, the flat oblong heads 10′ of the bolts 10 extend equally on each side of said bolts, and as said heads snugly fill the grooves 7 of the stock the bolts are thus interchangeable and reversible, so that the parts may be disassembled and reassembled regardless of their original positions. Furthermore, the top surfaces of the heads of these bolts and the bearing-surface of the guard or throat-gage are flush with each other, so as to form a smooth working face for the tool.

Preferably the stock and its handles are formed of metal in an integral casting, although the invention is not limited in this respect.

My invention is not limited to the precise details illustrated and described, and modifications may be made in the shape of the parts without departure therefrom.

Having thus described my invention, what I claim is —

1. In a spokeshave, the combination with a chambered stock of a cutter secured in said stock; and a guard or throat-gage cooperating with said cutter and having a working face curved in two directions and a plane back adjacent to the curved surface, said guard being adjustable to bring the working surface of said gage substantially to a position in line with the edge of the cutter.

2. In a spokeshave, the combination, with a stock and its handles, said stock having a chamber with an outwardly-curved wall and also having grooves and guideways at the ends of said chamber, of a longitudinally-curved cutter having flanges fitted in the ways of said stock; bolts having heads in engagement with said flanges; a guard or throat-gage having a straight back portion adjustably secured to the forward wall of the stock, the working surface of said guard or throat-gage projecting from said back portion and being curved both longitudinally and transversely, and said gage being adjustable on the stock to bring its working surface substantially into line with the edge of the cutter, substantially as and for the purpose specified.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to planes, and especially to knife-adjusting means therefor; and it has for its main object the provision of an improved tool of this type in which the knife can be set quickly in an adjusted position and held firmly in place without the use of adjusting-levers, the construction being such that all of the parts can be separated and assembled with great rapidity and precision.

My present improvements are designed more particularly for use in connection with planes of that type in which the knife or plane-bit is disposed at a comparatively-small angle with respect to the sole of the plane, thereby leaving but a small space at the rear end or heel of the plane for the knife adjusting and holding devices, and it is of the utmost importance in tools of this kind to provide holding and adjusting means which may be assembled and disassembled readily and operated a minimum distance for the purpose of effecting the proper adjustment of the plane-knife. It is essential, of course, that all of these parts should be so organized that the knife will be held firmly in place when set in any adjusted position, or else the adjustment of the bit might be changed and the proper operation of the tool prevented.

In the plane illustrated in the drawings of this application I have illustrated devices for obtaining two different adjustments of the plane knife or bit — one a rough adjustment, by means of which the knife may be brought quickly approximately to its proper position, and a fine adjustment, which will be effected, preferably, by means of a suitable adjusting-screw.

The device which I employ for obtaining the fine adjustment of the plane-bit constitutes one of the main features of this invention, and I may employ for this purpose an adjusting-screw having two diderent threads thereon, one of which coacts with a suitable member of the plane-bit and the other with the knife or its carrier. In this instance the knife is supported on a slide which will have a supporting-face oblique to the sole of the plane and will be shifted toward and from such sole by means of an adjusting-screw of the kind just described. Preferably the adjusting-screw will have two similar threads of different pitch, one of which will engage a fixed member of the body of the plane and the other of which will engage the slide, the parts being so organized that when the screw is turned it will move in the same direction through both the slide and the supporting member of the plane-bit and will at the same time cause the slide to be shifted toward and from such supporting member in accordance with the direction of movement of the screw.

The screw which I employ will be of two diameters in order that the smaller diameter thereof, which is at the point, may admit of the insertion of the reduced part through a proper threaded opening or fixed nut in the plane-bit; but the threads of the portion of the screw which is of larger diameter engage the corresponding internal threads of the member or fixed nut on the body of the plane. Hence it will be evident that in assembling the parts the reduced end of the screw may be passed through the threaded member of the plane-body and the point of the screw then inserted in the proper threaded opening or fixed nut of the slide, whereupon the screw may be turned into the two parts simultaneously by the turning of two similar threads of different pitch in the same direction, and thus draw the slide toward the supporting member of the plane-body while the screw is advancing through the threaded member or fixed nut of the latter. It will be noticed that this movement of the slide toward the fixed member on the body is due to the fact that the thread at the forward end of the screw is of quicker pitch than that near the head of the screw.

For the purpose of effecting the coarse adjustment of the plane-knife said knife and its support will have coacting holding members, one of the parts having a single holding member and the other a series, although each of the members of said series is adapted to engage said single holding member, so as to lock the plane-knife roughly in any desired position with respect to the throat of the plane. Usually the knife-support, which in this case will be the slide, will have a stop or rib projecting therefrom and adapted to enter any one of a longitudinal series of recesses in the plane-bit, these recesses being preferably in the form of parallel transverse grooves in the under side of the knife. It will be clear that these coacting holding means will permit a rough adjustment of the knife approximately in the desired position and that the fine adjustment may be effected afterward by means of the screw. Moreover, when the knife has such a row of recesses or grooves therein as that just described it will be apparent that the knife may be used in connection with planes of several different sizes, which is a matter of considerable importance.

In the drawings accompanying and forming part of this specification, Figure 1 is a sectional side elevation of a plane constructed in accordance with my present improvements. Fig. 2 is a transverse section of the plane-body and the slide, the section being taken in the line 2 2, Fig. 1, looking toward the heel of the plane. Fig. 3 is a perspective view of the knife supporting and adjusting slide, and Fig. 4 is a perspective view of the rear end or heel of the plane-body and illustrates the supporting member or guide on which the knife-adjusting slide is mounted.

Similar characters designate like parts in all the figures of the drawings.

As to many of the features thereof the body of the plane illustrated herein is similar to plane-bodies as ordinarily constructed. In this case the plane-body (designated in a general way by B) embodies as its essential features a flat base or sole s, side walls 2 2, and a support or guide, such as g, on which the slide will be carried. This guide may be of any suitable construction and is substantially U-shaped in this case in horizontal section and has a pair of oblique supporting-faces 3 3, on which the slide may move. At the inner side of the two side walls 4 4 of the guide I have illustrated a pair of channels or grooves 5 5, forming, with the oblique faces 3 3,ways for locating and guiding the slide.

As before stated, the knife or plane bit is intended to be supported on a slide shiftable by means of a feed-screw in order to obtain the fine adjustment of the knife, and this slide is indicated by S. It may be of any suitable construction, but in this case will have a pair of channels or grooves 6 6 in the under side of the main or fiat portion 7 thereof, these grooves being parallel to each other and so disposed as to cooperate with the guide-faces 3 3 and the grooves 5 5, as will be evident by referring to Fig. 2. It will be clear that this slide moves on the ways of the guide g toward and from the sole of the plane in a path oblique to such sole, this method of mounting the slide being well understood.

For the purpose of shifting the slide in the manner described I have illustrated at f 2 feed-screw of the type which has been hereinbefore referred to, the body portion of this screw being of two diameters and one portion having right-hand threads of one pitch and the other having corresponding threads of a different pitch. In this case it will be clear that the threads 10 are of a relatively-slow pitch, while the threads 12 are of somewhat-quicker pitch, and hence will be capable of shifting the slide with which they codperate so as to move said slide toward and from the back wall 13 of the guide g, in which back wall the feed-screw is mounted so as to lie obliquely to the sole s. The wall 13 of the guide is bored and screw-threaded to correspond with the threads 10 and form a fixed nut, in which the larger portion of the screw may work, while the slide S will have in this case a fixed nut in the form of a depending lug 14, internally screw-threaded to cooperate with the threads 12 of the point of the screw f. When the parts are properly fitted, the slide S may be shifted longitudinally of the slide-supporting faces of the guide, but will be held down and will be prevented from rising by reason of its connection with the screw f, which is braced firmly, and will be supported by the guide in such a manner that it will have no movement except in the direction of its length.

In assembling the parts the feed-screw, which will usually have a milled head, such as 15, of relatively-large diameter for the purpose of turning the screw freely, will be inserted through the opening 13′ until the threads 10 come into engagement with the threads of such opening, and the point of the screw will then be inserted into the opening 14′ in the fixed nut of the slide from the rear side thereof when the slide is in its extreme forward position on the ways of the guide. When the screw is turned to the right, the threads 10 will turn forward and the feed-screw will gradually pass through the opening 13’ toward the throat of the plane, and at the same time the threads 12 will turn forward in the fixed lug 14 of the slide and by reason of their quicker pitch will cause the slide to shift toward the wall 13. It will be seen that by employing a feed-screw of this type the assembling of the slide, the feed-screw, and the plane-body will be effected with a minimum movement of the slide on the guide g, since the screw advances into both of the fixed nuts in the same direction and does not, as is the case with a right and left hand screw, have to be inserted into one side of one nut and into the other side of the other nut. Hence the slide can be put in place approximately in its proper position, and its screw then turned into both of the fixed nuts a relatively-slight distance to position properly the knife to be supported and adjusted by the slide. This form of feed-screw and cooperating fixed nuts and the manner of assembling the parts described are of distinct utility, especially in those planes of the type illustrated herein having their knives set at a very slight angle to the sole, leaving but a small amount of available space between the rear end of the knife and the heel of the plane. By employing the devices shown herein this space is utilized to the best advantage, and all of the parts are of ample size and strength to operate properly and hold the bit firmly.

The plane knife or bit is indicated by k and may be of any suitably type. This knife and the slide S are intended to have coacting holding members, such as those hereinbefore described, for effecting the coarse adjustment of the bit. The holding member of the slide is indicated at 16 and is in the form of a stop or rib rising from a central wall or larger rib 17 of the slide S, the face 17′ of this wall or rib constituting the supporting-face on which the upper or rear end of the knife is carried. The other holding members, which cooperate with the stop or rib 16, are carried by the knife k and in the construction shown are in the form of a series of recesses or parallel transverse grooves 18 in the under side of said knife, these grooves forming between them transverse stops or ribs substantially similar to the ribs 16, the groove 18 being just large enough to receive the rib 16 and leave no extra space.

It will be clear that after the slide and its feed-screw are in place on the plane-body a rough adjustment of the knife may be obtained by simply placing the proper groove 18 over the stop 16 and placing the knife down upon the supporting-face 17′ of the guide. After this coarse adjustment is obtained the knife should of course be clamped firmly to the slide S, after which the adjusting-screw f may be turned to effect the fine adjustment of the knife.

Any suitable clamping means may be employed for holding the knife in place. That shown herein is indicated in a general way only and will preferably be of the type fully shown and described in Letters Patent No. 591,663, dated October 12, 1897. This main clamping device is in the form of a cam-lever (indicated by 20) carried by a knife clamp or plate c of ordinary construction, this latter being mounted at its forward end on a fixed part, such as 22, of the plane-body by means of a screw-and-slot connection, such as 23, of the usual type. This screw 23 serves to prevent sidewise movement of the forward end of the knife, while the cam-lever by raising the rear end of the knife-clamp c wedges the rear end of the clamp and the knife together and also forces the forward end of the clamp against the knife near the throat of the plane to hold the parts firmly in place.

After the rough adjustment of the bit has been obtained and the latter has been clamped in place by the means just described the screw f will be turned to obtain the iine adjustment of the knife, and it will be noticed that during this last-mentioned adjustment the part which operates directly to effect such adjustment of the bit is not only movable, but supports the knife directly and guides it, thus rendering unnecessary the employment of other or separate means for such purpose.

Having described my invention, I claim —

1. In a plane, the combination, with a plane-body comprising a sole and a pair of side walls, said sole having rigid with the inner face thereof a U -shaped slide-supporting guide the side walls of which extend in parallelism with the body side walls and have their upper edges inclined and recessed to form ways, and connected at their outer ends by an end wall having an internally-threaded opening; a slide mounted on said guide and recessed at its edges to cooperate with said ways, and provided at its under side with an internally-threaded depending lug working intermediate said side walls and on its upper side with a longitudinally-extending centrally-located rib having a transversely-extending rib or projection; a knife adapted to be clamped on said rib and provided with a plurality of transversely-extending recesses for the reception of said transverse rib to locate the knife in position; an adjusting-screw of different diameters working in said guide and slide and having two sets of similar threads of different pitch; and means for clamping the knife in position on said slide.

2. In a plane, the combination, with a plane-body comprising a sole and a pair of side walls, said sole having rigid with the inner face thereof a slide-supporting guide the side walls of which extend in parallelism with the body side walls and have their upper edges inclined, and which walls support at their outer ends a member having an internally-threaded opening; a slide mounted on said guide and provided at its under side with an internally-threaded depending lug working intermediate said side walls and on its upper side with a longitudinally-extending centrally-located rib; a knife adapted to be clamped on said rib, said knife and rib having, one a projection, and the other recesses cooperating with said projection to locate said knife in position; an adjusting-screw of different diameters working in said guide and slide and having two sets of similar threads of diderent pitch; and means for clamping the knife in position on said slide.

To all whom it may concern:

Be it known that I, ANDREW TURNBULL, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to planes; and the object thereof is to provide a simple and efficient means for holding the cutter-clamp firmly in engagement with the cutter; and it consists, essentially, of a cam-lever supported by the clamp, a locker preferably separate from and actuated by the cam-lever, and means on the clamp to cause the lever to approach and to recede from the clamp when the lever is turned.

In the form of the invention illustrated the locker alluded to consists of a pivot for the cam-lever loosely extending through an opening in the clamp and headed at its lower end, the lever having a cam portion adapted to be engaged by means on the clamp when the lever is turned in one direction, so that the lever will be caused to approach the cutter and thereby force the head of the pivot tightly against the cutter to hold the same.

In the drawings accompanying and forming part of this specification, Figure 1 is a plan view of a plane embodying my present improvements. Fig. 2 is a longitudinal central section of the same. Fig. 3 is a longitudinal central section of the cutter-clamp. Fig. 4 is a transverse section taken in line x x, Fig. 3. Fig. 5 is a bottom view of a portion of the cutter-clamp. Fig. 6 is a plan of the cam-lever, and Fig. 7 is a side elevation of the same.

Similar characters designate like parts in all the figures of the drawings.

The body of the plane is designated in a general way by B, and it consists of the usual base or sole 2, having the transverse mouth 3, through which the cutting edge of the plane-iron can pass, and the longitudinal side walls 5.

The cutter or plane-iron C, which is supported in any usual manner, as shown in Fig. 2, and the clamp-lever D may be of ordinary construction. The cutter C is supported against the inclined face 7 on the inside of the sole 2, said cutter, also bearing intermediate its opposite ends against the obliquely-disposed slide 12, working in a slide-way 13 of the boss or projection 14 on the sole 2. The boss or projection 14 has a longitudinally-threaded opening 15 to receive the threaded end 16 of the screw or spindle 17 , having at its outer end the disk or wheel 13, by which the screw 17 can be turned into and out of its seat, said screw having a peripheral groove 19 to receive a projection 20 on the slide 12, the other end of the slide being furnished with an oppositely-extending projection 21, adapted to be seated in one of the parallel notches 22, transversely formed in the under side of the cutter or plane-iron C, so that by turning the screw or spindle 17, through the medium of the disk or wheel 18, the cutter C can be moved back and forth, as occasion demands.

The foregoing description relates to a common form of smooth-plane to which my present improvements are adapted, although it is obvious that they may be applied to various sorts of planes. The clamp-lever D is held in place longitudinally by a screw 23, seated in a threaded aperture in the boss 10, said screw extending through an elongated or keyhole slot 24; near the forward end of the clamp.

The clamp D carries or supports a cam-lever L, consisting of a disk portion 30, centrally through which is passed the pivot-pin 31, constituting a locker, and a forwardly-extending curved operating-arm 32, passing through the segmental or curved slot 33 in the clamp, said operating-arm having a thumb-piece 34, to which pressure can be applied to turn the cam-lever L, so that the disk or working portion 30 of the lever will be caused to approach or recede from the cutter or plane-iron C in accordance with the direction in which the arm 32 is moved.

The pivot-pin 31 of the cam-lever loosely passes transversely through the clamp, it extending through the opening 35 in the bridge-piece or arch 36, which is on and is located above the normal plane of said clamp. The pivot-pin, which constitutes a cutter-locker, is headed or shouldered at its lower end, as at 37, and the disk or cam portion of the lever L, when the latter approaches the cutter, will act against the head 37 of the pivot-pin to force the same firmly against the cutter. The upper end of the pivot-pin is headed, as at 37’, to prevent it from dropping on the removal of the clamp.

For the purpose of obtaining the necessary motion of the lever toward the cutter the clamp is preferably provided with means adapted to engage a cam portion on the lever, as will now appear. The bridge portion 36 is furnished with the rounded projections 38 and 39, extending oppositely from the pivot-opening 35, and adapted to cooperate with the cam portions on the disk 30 of the cam-lever L. The upper face of the disk 30 is intersected by the radial cam-recesses 40 and 41 of differential depth, thereby to form the cam-faces 42 and 43, cooperative, respectively, with the projections 38 and 39.

When the parts are to be assembled, the clamping-screw 23 is passed through the wide portion of the slot and the clamp slid forward until the screw is in the narrow part of the slot 24, as shown in Fig. 1, the operating-arm 32 of the cam-lever during this time being in a position substantially agreeing with that shown by the dotted lines in said figure, at which time the two projections 38 and 39 on the bridge-piece are in line with the deepest portion of the cam-recesses. When the operating-arm 32 is grasped and thrown to the position shown by the full lines in Fig. 1, the cam portions 42 and 43 will be caused to ride against the projections 38 and 39,respectively, so that the disk portion 30 of the lever will be lowered and acting against the head 37 of the pivot-pin 31 will cause said head to bind against the cutter to lock the same firmly in position, the operating-arm of the lever also tightly wedging against the clamp to thereby prevent the retraction of the lever by ordinary jars. It will be observed that the operating-arm 32 of the cam-lever L, which extends forward and passes through the longitudinal slot 33 in the clamp, bears against the plate portion 33′ of the clamp, as indicated in Fig. 2, so that the clamp or plate portion thereof acts as a support for said operating-arm and materially decreases its liability of breakage.

Having described my invention, I claim —

1. A plane embodying a cutter; a clamp therefor provided with a bridge-piece or arch located above the normal plane of the clamp, the bridge-piece having a pivot-opening and also having projections on its under face; a lever consisting of a disk portion and an operating-arm passing through a slot in the clamp, the disk portion of the lever having a pivot-opening and a plurality of cam-recesses; and a pivot- pin extending through said pivot-openings and headed at its lower end, the pin being disposed transversely to the cutter, whereby when the lever is turned in a direction to lock the cutter the under face of the disk portion will be carried against the head of the pin to move the latter into locking engagement with said cutter.

2. A plane embodying a cutter; a clamp therefor provided with a bridge-piece having a pivot-opening, the bridge-piece having on its under face oppositely-disposed projections at each side of the pivot-opening, said clamp being also slotted; a lever consisting of a disk portion and an operating-arm extending through the slot in the clamp, the disk portion of the lever having a pivot-opening and a plurality of cam-recesses; and a pivot-pin extending through said pivot-openings and headed at its lower end.

3. A plane embodying a cutter; a clamp therefor having a slot; a cam-lever supported by the clamp, the latter having means to cause the working end of the lever to approach and recede from the clamp on the manipulation of the lever, and the lever being provided with a forwardly-extending arm passing through the slot and bearing against and sustained by the clamp; and a locker for the cutter, operated by said lever.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to planes, and it comprehends, essentially, a stock or body portion and a mouthpiece bodily adjustable on the stock.

In the form of the invention herein described the stock or body portion of the plane is constructed of wood, and the mouthpiece or plate is made of metal and is bodily adjustable on the stock or body portion in a direction transverse to the line of working movement of the plane, so that the sole of the latter can be dressed down to remove any unevenness in its surface from constant use and so that the mouthpiece or plate can be adjusted to compensate for the variation until its working face is flush with the sole or under surface of the plane-body.

In the drawings accompanying and forming part of this specification, Figure 1 is a plan view of a smooth plane embodying my present improvements. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of the plane with the cutter and its holding and operating parts removed. Fig. 4 is a plan view of the adjustable mouthpiece. Fig. 5 is a side elevation of the same. Fig. 6 is a longitudinal central section of a fragment of the plane, showing the adjustable mouthpiece therein. Fig. 7 is a longitudinal central section of a plane, representing a modification of the mouthpiece; and Fig. 8 is a longitudinal central section of a fragment of the plane-body illustrated in Fig. 7.

Similar characters designate like parts in all the figures of the drawings.

The stock or body of the plane represented in the fhawings is designated by B, and it is constructed, preferably, of wood. A metallic frame for carrying the usual cutter or plane-iron is designated by F, and is fastened near its opposite ends to the upper face of the stock B. The cutter or plane-iron is designated by C, and its clamping-lever by C’, and the operating mechanism for the cutter is designated by M, and as these parts are mounted in the usual manner in the loop or open portion 2 of the frame and are of common construction a detailed description thereof is deemed unnecessary.

My improved plane comprehends a stock or body portion and a mouthpiece bodily adjustable thereon, said mouthpiece consisting in the present instance of a plate adjustable in a direction transverse to the line of working movement of the plane.

The mouthpiece of the plane is designated by P, and it is represented consisting of a rectangular metallic plate set within a mortise or cavity 3, formed in the bottom or sole of the stock or body portion B. The mouthpiece or plate P has near its rear end the elongated mouth or slot 4, through which the cutter or plane-iron C may extend. The front and rear ends of the mouthpiece are beveled or inclined and fit against the similarly beveled or inclined walls 7 and 8 of the mortise, the latter being of a depth exceeding that of the mouthpiece P, as represented, respectively, in Figs. 2 and 6.

By reason of the construction just described the mouthpiece P can be set farther into the mortise 3 and its under face maintained flush with the sole or bottom surface 9 of the plane-body.

On an inspection of Fig. 6 it will be observed that the bevels or inclinations 5 and 6 on the front and rear ends, respectively, of the mouthpiece P correspond substantially with the inclination of the cutter or plane-iron C, so that if said mouthpiece be set in to a greater or less depth in the plane body or stock it will be adjusted in the direction of the length of the plane-iron and also of the stock or body portion, so as to maintain the proper working relation between the lower or cutting end of the said plane-iron and the mouth-piece.

The mouthpiece P is preferably held to the body portion by a screw passing through the body or stock B, the lower threaded end of which engages the internal threads 13 on the boss or hub 14, near the forward end of the mouthpiece. The screw extends through the slot or hole 15 in the frame F and the opening or aperture 16 in the body or stock B, a washer 17, serving its usual purpose, being placed between the screw-head 18 and the frame F. The opening 16 in the body portion B, which communicates with the mortise 3, is of different sizes or diameters, the wider or larger portion 19 being adapted to receive the internally-threaded boss 14 of the mouthpiece and its diameter exceeding that of the boss, so that as the mouthpiece is moved up or down in its mortise or recess in the body portion the holding-screw 10 can be properly seated in the boss without affecting the proper relation of the several parts, as will be apparent. For this purpose also the diameters of the reduced or narrower portion 20 of the aperature 16 and of the slot 15 in the cutter-carrying frame exceed that of the screw, so that the latter can be moved forward or backward in accordance with the adjustment of the mouthpiece.

It will be remembered that the mortise or recess 3 is preferably made deeper than the mouthpiece or plate P, and the mouthpiece or plate is provided with adjusting means adapted to bear against the roof of the mortise, said adjusting means consisting of a plurality of screws, as 21, disposed on the upper face of the mouthpiece, as shown in Fig. 4. The upper or slotted ends of the screws are adapted to bear against the roof of the mortise 3, so that the mouthpiece can be nicely fitted in its seat with its lower face true or flush with the sole of the plane.

In Fig. 2 the mouthpiece and the several cooperating parts are shown assembled in the plane-body. Let it be assumed that it is necessary to dress off the sole of the plane-body. In this event the plate-holding screw 10 is removed, so that the mouthpiece or plate P can be taken from its mortise or recess 3. The sole of the plane is then resurfaced. The several adjusting-screws are then driven slightly farther in their seats in the mouthpiece and the latter inserted in the mortise. If the lower face of the mouthpiece is flush with the sole, the holding-screw 10 will be inserted in place; if not, said mouthpice will be removed and the adjusting-screws will be driven farther into their seats, and this manipulation of the adjusting-screws will continue until the under face of the mouthpiece is alined with the sole; but it will be evident that it is but the work of a moment to properly adjust the mouthpiece. When the same is adjusted, the holding-screw 10 is placed in position.

In Figs. 7 and 8 I have illustrated a modified form of the invention wherein the adjusting-screws are dispensed with, the construction otherwise being similar to the preferred form. When it is desired to adjust the mouthpiece shown in Figs. 7 and 8, it is simply necessary to cut away the upper surface or roof of the mortise to correspond with the dressing off of the sole.

It will be observed on an inspection of Figs. 2 and 7 that the mouthpiece P constitutes also a clamping or resistance plate for assisting in holding the cutter-carrying frame in place on the stock, and the holding-screw 10, which is seated in said mouthpiece, also constitutes a part of the frame-securing means, as has been described.

By means of my present improvements the plane or under surface thereof may be readily repaired from time to time by the user, so as to maintain the implement in perfect working order for a long period of time, hence materially prolonging its life and reducing the cost of the tool proportionately to the amount of work done. At the same time the mouthpiece of the wood body being adjustable, as hereinbefore set forth, said mouthpiece is maintained in proper form relatively to the stock and to the cutter regardless of the extent to which the bottom or the sole of the plane may be cut away in resurfacing.

Having described my invention, I claim —

1. A plane comprising a stock having a mortise in its under side, the front and rear walls of which are beveled, said stock also having an aperture extending therefrom and communicating with the mortise; a mouthpiece having its ends beveled to conform to the walls of the mortise; screws carried by the mouthpiece and bearing against the roof of the mortise; and a holding-screw pressing through and of less diameter than the aperture in the stock and having its lower end in threaded engagement with the mouthpiece.

2. A plane comprising a stock having a mortise the front and rear walls of which are beveled, and also having an aperture extending entirely through the stock and communicating with the mortise, said aperture being of different sizes; a mouthpiece bodily adjustable in, and of less depth than, the mortise and furnished with a threaded boss or stud of a less diameter than the wider portion of said aperture, said mouthpiece having its opposite ends beveled to correspond with the beveled surface of the front and rear walls of the mortise; a series of screws threaded in the mouthpiece, the heads of the screws bearing against the roof of the mortise; and a holding-screw passing through the aperture in the stock from the upper side, and having its lower threaded end in engagement with said boss, the screw being of a less diameter than the narrower portion of the aperture through which it passes.
