To all whom it may concern:

Be it known that I, JOHN BAHMILLER, a citizen of the United States, residing at Salem, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Fastenings for Plane-Bits, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in fastenings for plane-bits and has for its object to provide a fastening which will admit of the bit being readily adjusted to the various positions desired.

A further object of the invention resides in providing a bit having a central longitudinal slot, the one wall of which is provided with rack teeth and a still further object resides in providing means on the securing member between the bit and cap-iron adapted for cooperation with said rack teeth to adjust said bit to its various positions.

A further object of the invention resides in providing a device which is extremely simple and durable in construction, inexpensive to manufacture and one which will be very eflicient and useful in operation.

With these and other objects in view, the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claim.

In the accompanying drawing forming a part of this application, Figure 1 is a plan view of a bit showing my improvements applied to use thereon. Fig. 2 is a vertical longitudinal section therethrough; and Fig. 3 is a perspective view of the sleeve member adapted to cooperate with the rack teeth on the bit.

In describing my invention, I shall refer to the drawing in which similar reference characters designate corresponding parts throughout the several views and in which —

1 indicates a bit such as is used in the usual bench plane or the like, the same being provided with a central longitudinal slot 2, the forward end of which is enlarged as shown at 3. The under face of the bit 1, at the outer end thereof, has counter-sunk therein and welded or otherwise similarly secured thereto, the hard metal surface 4, which extends to the cutting edge thereof and one wall of the slot 2 is provided with rack teeth for the greater portion of its length, as shown at 5. A cap-iron 6 of the usual construction, is also provided, the same having an opening 7 therein, and any other such openings as are demanded by the construction of the plane to which the same is to he applied. This opening 7 is threaded and adapted to receive in engagement therewith, the threaded end of a screw 8 which is extended through the slot 2 of the bit 1. In order to adjustably secure the bit and cap-iron together, however, and properly support the screw 8, I provide a substantial sleeve member 9, which is greater in diameter than the width of the slot 2 and is externally reduced at one end thereof to permit a portion thereof to extend through said slot. This reduced portion is of substantially the same diameter as the width of said slot and is provided with rack teeth, as shown at 10, to engage the teeth 5 in the one wall of said slot. This reduced portion with its rack teeth 10 thereon forms a substantial gear and the outer periphery of the enlarged upper portion of said member 9 is knurled to be readily grasped by the operator and turned. The inner periphery of this sleeve member from the enlarged end thereof, is increased in width as shown at 11 to provide an annular shoulder and as the screw 8 is adapted to extend through this sleeve member, the head of said screw may be readily seated on this annular shoulder.

In setting up the device, the sleeve member 9, with the screw 8 extended therethrough, is first disposed in the enlarged portion 3 of the slot 2 and the cap-iron 6 brought into position to be engaged with the threaded end of said screw. The sleeve is then moved into the slot 2 until the teeth 10 are engaged with the teeth 5 of said slot, whereupon said member 9 is rotated until the bit is properly adjusted with respect to the cap-iron. When the proper adjustment has been made, the screw 8 is then turned until the same securely clamps said member 9 in its adjusted position and the bit is then ready for use. Should, during the operation of the plane, it be desired to adjust said bit, it is only necessary to turn the screw 8 in the opposite direction to loosen the same, whereupon the member 9 may be rotated, which operation will adjust said bit on the cap-iron. The screw is then tightened to securely retain the bit in the desired position.

From the foregoing it will be seen that I have provided a simple, inexpensive and efficient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set forth, it is obvious that various changes in form, proportion and in the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

The hard metal surface 4 which is counter-sunk in the under face of the bit 1, and extends to the cutting edge thereof, is a plate which will prevent the cutting edge from being unnecessarily nicked during the use of the device and thereby obviate the necessity of constantly sharpening the same, The provision of such a plate on the bit will not materially add to the cost thereof and in the end will save considerable time and expense.

Having thus described this invention, what I claim is:–

In a plane, the combination with a cap iron having a threaded opening arranged about centrally therein; of a bit provided with a longitudinal slot terminating in an enlargement at one end thereof, one wall of said slot being provided with teeth extending for the greater portion of its length, a sleeve disposed in the slot of said bit having teeth formed on the outer periphery thereof, in engagement with the teeth of the one vvall of said slot, the teeth on said sleeve also contacting lightly with the opposite wall of said slot to prevent a loose movement of the sleeve therein, a disk-like head member formed on the upper end of said sleeve to project on opposite sides of the slot in said bit and rest on the top face of the latter, said head member being of less diameter than the diameter of the enlargement of said slot and provided with a socket in the top face thereof, means provided on the outer peripheral edge of the head member, whereby to readily grasp the same, and a headed screw disposed through said sleeve and engaged at its lower end with the threaded opening of said cap iron, the head of said screw being received snugly in the socket of the head of said sleeve to bind tightly therein and retain the bit in any adjusted position with respect to the cap iron.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

To all whom it may concern:

Be it known that I, JOHN W. CARLETON, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new useful Improvements in Plane-Irons, of which the following is a specification.

My invention relates to improvements in plane irons or cutters; and the object of my improvement is to facilitate securing the bit-adjusting bolt to the body of the cutting-bit or plane-iron.

In the accompanying drawings, Figure 1 is a plan view of my plane-iron. Fig. 2 is a side elevation of the same. Fig. 3 is a reverse plan view of the same. Fig. 4 is a detached side elevation of the adjusting-bolt with the nut removed. Fig. 5 is a plan view of the same.

A designates the cutting-bit, having the usual longitudinal slot 6, within the lower end of which is the bolt 7, by which to connect the said cutting-bit with any ordinary devices for adjusting the said bit longitudinally. This bolt has its head 8 projecting from the under side of the bit and is provided with a slot 9 to receive a projection of the lever or other device for adjusting the bit longitudinally. A portion of the head is slabbed off on opposite sides, as at 10, Figs. 4: and 5, to let the said bolt-head into the slot 6 of the bit, with the said slabbed-off portions acting in connection with the sides of the slot to prevent the said bolt from rotating within the said slot. The end or body of the bolt 7 is screw-threaded and receives a nut 11, which rests upon smooth surfaces on the upper broad side of the cutting-bit or plane-iron and by which nut the said bolt may be adjustably secured at any desired position in the lower end of the said slot. This nut is provided with a screw-driver slot 12 to facilitate securing it in place. As shown, the periphery of the said nut is also provided with a knurled surface to facilitate turning the nut with one’s fingers.

Upon each side of the slot 6, from its lower end upwardly a part of the length of the said slot, there is formed a roughened face 13, Fig. 3, which may be simply a series of alternate fine grooves and ridges extending from the edges of the slot 6 outwardly about the same distance that the bolt-head 8 projects beyond the said edges. These roughened surfaces come under the non-rotating head of the bolt, which is drawn firmly against them by tightening up the nut. This nut bears on smooth surfaces, so that it turns smoothly when it is rotated to draw the bolt-head against the roughened surfaces on the opposite broad side of the cutting-bit, whereby the bolt can be readily and firmly secured in its adjusted position without applying excessive power to the nut. This bolt is designed to be set in the proper position to connect with the longitudinally-adjusting devices when the lower end of the cutting-bit is within its proper range of movement relatively to the throat of the plane-stock. When the cutting-bit is shortened up by wear and repeated grinding, so as not to have the proper range of movement relatively to the throat, the bolt can be readjusted accordingly.

I claim as my invention —

The herein-described cutting-bit having the central longitudinal slot with adjacent smooth surfaces on one broad side of the said bit, and roughened surfaces adjacent to the said slot on the opposite broad side of the said bit and the non-rotating bolt fitted to the said slot and provided with means for being connected with the longitudinally-adjusting devices for the said bit, the said bolt being arranged in the said slot with its head bearing on the said roughened surfaces on one broad side of the said bit and the nut bearing on the opposite broad side of the said bit.

To all whom it may concern:

Be it known that I, SAMUEL JONES, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Ohio, have invented certain new and useful Improvements in Plane-Bits, of which the following is a specification.

Planes designed for carpenters’ and joiners’ use have the bit for the most part reinforced and strengthened by a cap or stay plate, held thereto by a clamp bolt or screw. When sharpening the bit either by grinding or whetting, it becomes necessary to remove the cap or stay plate, so that the face of the bit may be presented to the grindstone or oil-stone to enable the removal of the wire-edge and the securance of a keen cutting edge. The removal and the proper replacement of the cap-plate are almost always attended with vexation for one reason or another, which it is the purpose of the present invention to overcome. This invention enables the proper sharpening of the bit without necessitating the removal of the cap-plate, which is composed of sections hingedly connected, the lower section being free to be turned back upon the bit out of the way and the upper section being secured to the bit in the usual manner to admit of adjustment of the cap or stay plate as the bit wears away.

The invention consists of a plane-bit having a cap or stay plate hinged thereto, so as to be thrown back out of the way to admit of proper sharpening of the bit.

The invention also consists of a cap or stay plate for plane-bits composed of hinged sections.

The invention further consists of the novel features, which hereinafter will be more fully described, claimed, and illustrated in the accompanying drawings, in which —

Figure 1 is a perspective view of a plane-bit embodying the invention. Fig. 2 is a view similar to Fig. 1, showing the lower section of the cap or stay plate folded back upon the bit. Fig. 3 is a perspective view of the bit and cap-plate detached.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The plane-bit 1 may be of any pattern or make adapted for the stock of a carpenter’s or joiner’s plane and is provided with the cap or stay plate 2, secured thereto by the bolt or clamp screw 3. The cap or stay plate is composed of sections 4 and 5, hinged together in any way to admit of the lower section 4 folding back upon the bit out of the way. The stay portion 4 is hinged to the bit 1 through the part 5 and can be turned instantly to occupy either an operative position or be out of the way. The part 5 can be adjusted to admit of shifting the cap or stay plate to compensate for wear of the bit. After the bit has been removed from the plane-stock (not shown) it may be sharpened in the accus-
tomed way by folding the stay-section 4 upon the bit, as shown in Fig. 2, it not being necessary to remove the cap or to loosen the clamp-screw. After the bit has been sharpened the section 4. is turned into a normal position and the bit replaced in the stock in the usual way. This part 4: constitutes, in effect, the reinforcement for the bit and is clamped thereto by the same means employed for securing the bit to the stock or frame.

Having thus described the invention, what is claimed as new is —

1. A plane-bit having a reinforcement hingedly connected therewith, substantially as described.

2. A cap-plate or stay for a plane-bit composed of hinged sections, substantially as specified.

3. In combination with a plane-bit, a stay, an attaching-section having the stay hinged thereto, and means for adjustably connecting the attaching-section to the said bit, substantially as set forth.

4. In combination with a plane-bit, a cap-plate composed of hinged sections, and means for adjustably connecting the upper section with the bit, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, CHARLES A. PAUL, a citizen of the United States, residing at Orlando, in the county of Logan and Territory of Oklahoma, have invented certain new and useful Improvements in Planes; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to planes, and more particularly to plane-bits.

My object is to provide an improved and simple plane-bit which will be capable of quick and easy adjustment or removal.

The invention consists of certain novel features and combinations appearing more in detail hereinafter.

In the accompanying drawings, Figure 1 is a sectional side elevation, and Fig. 2 a top view.

A designates the plane-body, which is provided with the usual handle B.

The sides of the body are provided with respective rearwardly-inclined bit-slides C, which have arc-shaped notches E in their upper ends. I also proyide the sides with inwardly-projecting lugs G and H, through which pass respective clamping-screws I and J.

My improved bit K is provided with integral upwardly-projecting screws L and M, on which are located circular adjusting-nuts N and O, which project into the notches E and F.

The bit is adjusted in the following manner: The nuts are turned to advance or retreat the bit, and when properly adjusted the clamping screws are screwed down, thus holding the bit firmly in adjusted position. The bit is not quite the width of the plane-body, so that either nut can be adjusted to slightly tilt it either to the right or left, so that the cutting edge will lie parallel with the bottom of the plane.

Having thus described the invention, what is claimed as new is —

1. In a plane, the combination with a plane-body of inclined bit-slides securely fastened thereto, a bit having screw-threaded arms, located at opposite sides thereof and secured thereto and nuts carried on said arms and engaging with the bit-slides whereby either or both sides of the bit can be adjusted.

2. In a plane, the combination with a plane-body, of inclined bit-slides secured thereto, said slides being provided with notches, a bit movable on the slides and having screw-threaded arms secured thereto and located at opposite sides thereof, and circular nuts carried on the arms and loosely received in the notches.

3. In a plane, the combination with a plane-body, of inclined bit-slides securely fastened thereto, said slides being provided with notches, a bit movable on the slides and having screw-threaded arms at its opposite sides, nuts carried on the arms and loosely received in the notches, ears secured to the plane-body, and clamping-screws passing through the ears and binding on the bit-slides.

4. In a plane, the combination with a plane-body, of bit-slides secured to the body, a bit movable on said slides, said bit being provided with integral screw-threaded arms L and M, circular nuts N and O loosely received on the bit-slides, and clamping-screws I and J adapted to bind on the bit-slides.

5. The combination with the plane-stock having its sides provided with rearwardly-inclined bit-slides and arc-shaped notches at their upper ends and lugs projecting inwardly from the inner walls of the opposite sides, of a bit mounted for movement in said slides beneath said lug and provided with integral upwardly-projecting screws, one at each edge, nuts on said screws projecting into said notches and set-screws passed through said inwardly-extending lugs at right angles to the screws and bearing against the bit whereby the bit may be adjusted in either direction by manipulation of said nuts and also tilted to either the right or left to bring the cutting edge thereof parallel with the bottom of the plane, substantially as described.

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

CHARLES A. PAUL.

To all whom it may concern:

Be it known that we, JUSTUS A. TRAUT and CHRISTIAN BODMER, citizens of the United States, residing at 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 has for its object to furnish an improved tool of this class having, in connection with the plane-iron or knife, a combined knife-actuator and knife-edge cap adapted for maintaining, when properly clamped in place, a perfect bearing between the end of the knife and said cap; and it also has for its object to furnish such a knife-controlling member, in which the knife-edge cap, as a whole, will be capable of a clamping movement independently of and relatively to the knife-actuator or main portion of such knife controlling member.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side elevation, partially in section, of a portion of an ordinary smooth-plane furnished with our present improvement. Fig. 2 is a plan view of a portion of the knife-controlling member of the plane iron or knife embodying one form of our present improvement. Fig. 3 is an edge view of the cap shown in Fig. 2. Fig. 4: is a view similar to Fig. 2 and illustrating a modification of the cap shown therein. Fig. 5 is an edge view of the cap shown in Fig. 4. Figs. 6 and 8 are plan views similar to Figs. 2 and 4 for illustrating other modifications of the cap; and Figs. 7 and 9 are edge views of the forms of the cap shown in Figs. 6 and 8, respectively.

Similar characters designate like parts in all of the figures.

Our present improvement comprises a knife-controlling member for a plane-iron or knife, and having, in combination, a substantially-rigid knife-actuator, and a substantially-rigid knife-edge-cap or clamp formed integral with each other, and movable bodily, the one relatively to the other. It also comprises, in combination with said knife-actuator and the knife-edge cap, a resilient connection or spring-joint intermediate of said main portions of the knife-controlling member, and, in order to obtain a more perfect resilient relation between the knife-actuator and the knife-edge cap, the knife-engaging face of the cap, which is adjacent to said resilient connection, projects beyond the plane of the knife-engaging face of the knife-actuator, so that the knife-edge cap will have a full bearing upon the knife at both ends of said cap, and independent ofthe knife-actuator, and an oscillatory, yielding movement, transversely of the plane of the knife-controlling member, about the fulcrum or axis formed by the rear knife-engaging bearing-face or fulcrum-edge of the knife-edge cap.

We have shown, in Fig. 1, the principal portion of the body of the ordinary smooth-plane, of the class usually made of iron, and having the parts common to such planes, viz: a plane-iron or knife, a cap for the knife, a clamp for the cap, means in connection with the cap and adapted for adjusting the knife, a handle or knob at the front or left-hand end of the plane-body, and a handle (not shown), at the rearward or right-hand end of the plane-body.

In the drawings, the plane-body is designated in a general way by B, the plane-iron or knife by K, the knife-controlling member or cap by C, and the usual, forward handle, or knob, by H. This knife-controlling member or cap is shown affixed to the knife or plane-iron by means of the usual clamping screw 2; and a knife-actuating lever 3, which will be supported upon the frame or body of the plane in some usual or well known manner, is shown engaging in a mortise or slot, formed at the point 4 in the knife-controlling member, for the purpose of adjusting the knife and its controlling member together, upward or downward under the cap-engaging clamp L.

According to our present improvements, the knife-controlling member, which, as before stated, is designated in a general way by C, comprises two principal portions separated, at about the point 5, by a connection which will permit movement of one of the members, such as the knife-actuator 6, relatively to the other member, or knife-edge cap 7, in a direction transversely of the plane of said knife-controlling- member considered as a whole. This connecting member is shown herein, in the preferred form thereof, as a spring-joint, formed by a connecting portion or portions 8, of relatively-small cross-sectional area, transversely of the knife-controlling member, as compared with such area of said member at other points in the length thereof. This connection, which, in the forms of the device herein shown, constitutes a yielding or spring-joint, connects the knife-actuating portion 6 of said knife-controlling member with the knife-edge cap 7 thereof, in such a manner that these main portions are each movable, as a whole, relatively to the other, in a direction substantially transverse to the plane of said knife-controlling member, that is to say, each of said main portions has a slight, oscillatory movement, relatively to the other, about an axis intermediate of said main parts. In the manufacture of articles of this class, it has been found, that a perfect organization of the parts of a plane, — such as will bring the edge of the cap into exact parallelism with the cutting-edge of the bit- — is exceedingly difficult, owing to the liability of each member of the organization having a very slight error, when formed by the ordinary methods of manipulation. The clamping-edge of the cap, for instance, even if ground with precision, after tempering, and especially, if unevenly tempered, might not be an exact straight line in the direction of the plane of the bit, but have a slight bend in the same; and this is the frequent case in actual practice. Hence, it will be evident, that if provision is made for a slight torsional, or twisting movement of the cap, relatively to the actuator, a perfect and even bearing of the forward edge of the cap, upon the knife, will be assured.

It will be remembered that, in planes of this class, as ordinarily constructed, the cap generally employed, and which, in some of its features, is substantially similar to the knife-controlling member described herein, is required to be accurately adjusted relatively to the extreme or cutting edge 10, of the knife of the plane, so as to properly turn the shaving in the throat of the plane, as said shaving is stripped, by the knife-edge, from the body of the piece being planed. This adjustment is effected, in practice, by means of the set clamp-screw 2, the point of which is engaged in the knife-controlling member, and the shank of which travels in the usual, central, longitudinal slot in the plane-iron or knife.

When this clamp-screw is loosened, the cap may be adjusted longitudinally on the knife, with its forward end more nearly adjacent to, or more remote from, the cutting edge of the knife, and is then re-affixed to the knife by tightening said clamp-screw. The cap being properly adjusted, relatively to the knife, and the knife being also properly adjusted, with its cutting edge in the desired position relatively to the sole of the plane, this latter adjustment being effected by means of the lever 3, or other adjusting device, commonly employed for this purpose, the clamp L is then brought into locking engagement with the outer face of the cap-portion 7, of the knife-controlling member, and secured in that position, so as to hold the said clamp rigidly upon such knife-edge cap of the knife-controlling member, and thereby obtain a similar, rigid engagement between the bearing-faces 7′ and 7”, at the forward and rearward ends of the knife-edge cap, and the upper face of the plane-iron or knife, as shown in Fig. 1. The clamping force, exerted by the clamp L upon the arched knife-edge cap 7, readily springs or bends the relatively-small connecting portion, or spring joint 8, of the knife-controlling member C, thereby bringing both the forward edge 7′, of the clamp-portion or knife-edge cap of said knife-controlling member, and the rearward fulcrum edge 7”, thereof, into full bearing engagement with the plane-knife or plane-iron, so as to hold said knife and the knife-edge cap in full and proper bearing contact, the one upon the other, at all points in the transverse bearing-faces of the same, and this, notwithstanding any irregularity in the form of the actuator portion 6, of the knife-controlling member, or in the manner of fastening this actuator portion to the knife itself.

In all of the forms of our improvement, that are herein shown and described, the same general organization of parts is maintained, viz.: a knife-actuator and a knife-edge cap connected transverse to the plane of the knife-controlling member in which they are embodied, and a preferably resilient joint, intermediate of these main portions of the knife-controlling member, and forming said connection therebetween. In each case, the connecting-member, between the shaft and the actuator, is of relatively-great inherent mobility, or resilience, transversely of the knife-controlling member, as compared with the mobility, or resilience, of such cap or actuator; so that each transverse portion of the two main parts of the knife-controlling member will be of relatively-great inherent rigidity, as compared with the member which connects them.

In Fig. 2, the connection portion of the combined knife-actuator and knife-edge-clamp is shown consisting of the two edge-bars 8–8, tying together the two main portions, and at the ends of the elongated, transverse slot or opening 12. In this case these connecting bars constitute a relatively yielding portion, or spring-joint, entirely independent of the main portions of the knife-actuating member, except at the extreme lateral edges thereof; and, for the purpose of allowing this joint to operate more freely, the knife-actuator 6 will usually be slightly elevated at 6’, rearward of said joint, as shown in Fig. 3, by contrast with the dotted lines illustrating the position of the knife relatively to its controlling member, so as to isolate the relatively-narrow bearing-face 7”, of the knife-edge clamp from the body of said clamp, and from the knife-actuator, whereby a fulcrum-edge is obtained intermediate of the knife-edge cap and the knife-actuator, about which the knife-edge cap, or clamp, has a limited, oscillatory movement, relatively to the knife-actuator and independently thereof.

The other modifications of the knife-controlling member, herein shown and described, are similarly illustrated, as to their relation to the knife, in Figs. 5, 7 and 9, respectively, in all of which views, the fulcrum-edge of the rear bearing-face 7”, of the knife-edge cap is independent of the under side of the knife-actuator, and projects beyond the plane thereof.

In Fig. 4, the connection portion of the knife-controlling member is shown as a single connecting-bar, formed substantially intermediate of the lateral edges of said knife-controlling member, by recessing said edges, intermediate of the knife-edge clamp and the knife-actuator, for considerable distances inward from said edges, and in line with each other, as shown at 12, in said figure. By this organization of the knife-edge clamp and the knife-actuator with the connecting-joint 8, the two main portions of said knife-controlling member are rendered torsionally movable, relatively to each other, as well as oscillatory, relatively to each other about the connecting joint transversely of the plane of such member.

In Figs. 6 and 8 the relatively-reduced connecting portion or joint between the knife-edge clamping-cap and the knife-actuator is obtained by transversely channeling or grooving the knife-controlling member transversely thereof and intermediate of its two main portions. In Fig. 6 this channel is formed in the upper side of said knife-controlling member, while in Fig. 8 the channel is shown as being in the under side thereof.

It will be evident from the foregoing that, by organizing the knife-edge cap and the knife-actuator, so that said cap will be capable of independent, though limited, oscillatory movement in a direction substantially transverse to the plane of the knife-controlling member, said cap will be capable of exerting its clamping action upon the knife-edge entirely independently of any clamping action exerted by the knife-actuator, and that, as the clamping force of said cap is all exerted upon two relatively-narrow bearing-faces, running transversely of the knife-edge cap, an augmented clamping effect will result when the clamp L, is forced into locked engagement with said cap; also that the entire clamping force of this clamp L will be confined to the cap 7, and will be transmitted to the bearing-faces 7′ and 7” , thereof, owing to the isolation of the latter bearing-face from the under side of the knife-actuator. A perfect clamping action thus results from the organization of the several parts of the knife-controlling member in which the two main portions thereof are joined by a connection relatively more yielding, transversely of the plane of said member, than either of said portions is in a direction transversely of itself.

Having thus described our invention, we claim —

1.

To all whom it may concern:

Be it known that I, WILLIAM F. KELLETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plane-Irons; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to that class of plane irons in which the cutter or blade is quite thin and is supported by a separate, rigid back plate.

The invention has for its object the improvement of the cap piece so as to more securely hold the blade and prevent its vibrations.

It consists in the use of a cap having a transverse rib between its edge and the main screw, the cap being rigid between the rib and the screw and elastically flexible below the rib and being so formed that when applied it must be depressed by the action of the wedge, ordinarily used in securing plane-irons, before the rib comes into contact with the blade.

In the accompanying drawings, Figure 1, is a longitudinal section of the plane iron on the line 1–1 of Fig. 2. Fig. 2, is a plan view of the iron. Fig. 3, is a perspective of the cap. Fig. 4 is a sectional view on the line 1–1 of Fig. 2, with the outline of the body of the plane in dotted lines.

The blade is shown at A. It is of finely tempered steel and is quite thin so that in sharpening there is no superfluous metal to cut away. This blade rests upon a back plate B, of softer metal but of greater thickness so as to be quite rigid. The back plate reaches approximately to the cutting end of the blade, and preferably has a slight rib as shown at h, across its end for contact with the blade so that the latter does not rest flatly against the surface of the back plate, the space between the two being so slight, however, that in drawing them together by means of the binding screw the flexure of the blade is scarcely perceptible. This feature is not new in this application.

The cap consists of a rigid body portion b, falling short of reaching the cutting edge of the blade A, by approximately one-half inch, and a flexible extension piece a, secured firmly to the under side and at the lower end of the body portion by the rivets e, and reaching approximately to the end of the blade. This cap extension is bowed outwardly from the end of the body portion, its lower edge being curved downwardly so as to cross the plane of its upper end. The body portion, b, of the cap is provided with the ordinary screw threaded aperture, c’, within which is set the main screw, c, which extends through longitudinal slots in the blade A, and back plate B, its head binding against the under surface of the back plate B, so as to draw the cap down upon the blade A, interposed between the cap and the backing piece. When the three members are first brought together the cap touches the blade only at its extreme ends. The main screw is turned up so as to draw them firmly together but not sufficiently to bring the rib, d, into contact with the blade. When the iron is adjusted to the plane H and the wedge K driven to its place the cap is still further depressed so as to bring the rib d, firmly against the blade A. It is important that the cap bear firmly against the lower end of the blade. This is certainly attained only by depending upon the wedge K to depress the cap at the rib, for were the main screw to be relied upon for this purpose there would be danger of bowing the cap downwardly between the rib and the screw, thereby causing its lower end to tilt upwardly, at least to relieve the pressure of the flexible end upon the blade. Heretofore it has been usual to secure a blade of this character by a cap having no bearing between the main screw and its edge. The result has been that the blade has, particularly when used on hard wood, bowed upwardly from the back plate; that is, the end of the back plate has served as a fulcrum upon which it has turned. The stiffness and elasticity of the blade have brought it back quickly to its normal form, and as a result of the conflicting action — the pressure at the edge tending to bow the blade, its stiffness and elasticity tending to preserve its original form — the blade has been caused to vibrate rapidly, to the manifest detriment of the tool.

By the construction herein shown and described an unyielding, intermediate point, or line of bearing, is secured at d, sufficiently removed from the edge of the blade to wholly counteract this tendency, and a cap is provided which under all conditions holds the blade immovably to its seat upon the back plate. At fand f’, are shown a bolt and nut for securing the upper end of the blade to the back plate in the usual manner.

While I show and describe the cap as of two pieces secured together it is obvious that it may be of a single piece provided it meet the conditions of having a firm transverse rib between its edge and the main screw, and is substantially inflexible between this rib and the main screw, and flexible and elastic below the rib, and has its flexible portion curved so that its edge falls below the rib, thereby insuring a close joint between the edge of the cap and the blade.

I am aware that it is known to secure a bearing above the edge of the cap by the use of a supplemental flexible cap interposed between the rigid cap and the blade, but such construction does not meet the requirement for a firm bearing upon the blade to prevent its vibration.

I claim as my invention —

l. In a plane iron, the combination with a thin cutting blade, A, of a rigid back plate, B, for supporting the blade, and a cap for covering the blade, such cap comprising a rigid portion, b, having bearings at its upper and lower ends upon the blade, and a flexible extension, a, adapted to bear upon the blade contiguous to its cutting edge, substantially as described and forthe purpose specified.

2. The combination in a plane iron, with a thin cutting blade and a rigid back plate for carrying the same, of a cap piece comprising a rigid portion b, and an elastic extension piece a, secured to the under side of the lower end of the portion b; and being bowed outwardly, its extreme end normally crossing the plane of its inner or attached end, and being adapted to bear against the blade contiguous to its cutting edge, substantially as described and for the purpose specified.

3. The combination in a plane iron, with a thin cutting blade and ia rigid back plate for carrying the same, of a cap piece having a transverse rib and being elastic below this rib and rigid above it and being so curved that when applied to the blade the rib does not touch the blade until the cap is compressed, substantially as described and for the purpose specified.

4. In a plane iron, the combination of a rigid back plate, a flexible cutting blade carried by the back plate, and a cap piece having its lower end flexible and its upper portion rigid and having a transverse rib at the juncture of the flexible and rigid portions and being adapted to bear upon the blade, whereby positive contact is insured between the blade and the back plate directly below the rib when tl1e iron is adjusted to the plane, substantially as described and for the purpose specified.

In testimony whereof I affix my signaturein presence of two witnesses.

_________________

To all whom it may concern:

Be it known that I, GRANVILLE W. WRIGHT, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Bench-Planes; and I do hereby declare the following, when taken in connection with 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 longitudinal central section of the plane complete; Fig. 2, a top or plan view of the stock with the bit removed; Fig. 3, an under side or rear view of the bit; Fig. 4, a transverse section cutting on line x–x of Fig. 1 looking forward.

This invention relates to an improvement in that class of bench-planes in which the stock is made from metal, and in which the bit is made mechanically adjustable both as to depth of cut and as to transverse position, and particularly to those planes of this class in which the bit is single, that is without an adjustable cap upon its face. In the more general construction of planes of this character the transverse adjustment of the bit to vary its edge with relation to the face of the stock, is produced by a lever hung in the stock below the bit, the lever constructed with a projection which will extend up into a notch or slot in the bit, consequently the wear to which the bit may be subjected is considerably limited, as after a little wear, the point of engagement of the bit with the adjusting lever will have passed so far down from the lever as to prevent such engagement, consequently after a little wear the bit must be exchanged for a new bit with which the adjusting-lever may engage.

The object of my invention is to provide the lever a laterally adjusting arrangement, but so as to make the extent of wear to which the bit may be subjected unlimited so far as the adjusting device is concerned, and it consists in the construction hereinafter described and particularly recited in the claims.

A, represents the stock, of usual construction, B, the bit which is adapted to rest upon the bed below, in the usual manner, and upon its upper side is arranged a clamping lever C, which engages with a screw D, from the bed, through a slot in the bit, and between the bit and the lever above or in rear of the screw D, an adjusting-screw E, is arranged provided with a head F, by which it may be rotated. One end of the screw is threaded into a corresponding nut in the lever C, and the other end bears upon the upper side of the bit, so that by turning the screw, the bit will be clamped upon its bed, or released therefrom, accordingly as the screw is turned in one direction or the other, a common and well known device for securing the bit in place.

Upon the under side of the bit a toothed rack G, is formed, into which the teeth H, of a segment or lever H’ hung upon an axis I, below the bit work, the hub of the segment extending rearward, forms an arm J, by means of which the segment may be swung in a longitudinal plane for the adjustment of the bit to produce a greater or less extent of depth of cut. The segment is operated by means of an adjusting-screw K, in a well known manner. Upon the under side of the bit a lever is hung directly to the bit, upon a pivot L. As here represented the lever is of thin metal, and the pivot is screwed through a corresponding hole in the lever into the bit, so as to permit the lever to swing freely. One arm M, of the lever extends rearward, and terminates in a suitable handle N, the other arm O, extends downward below the pivot L, and as seen in Fig. 3. On the stock below the bit, a longitudinal recess is formed by two upwardly projecting ribs or long narrow posts P P, see Figs. 2 and 4. These ribs are parallel with each other and with the plane-stock with respect to the length thereof, and have their upper edges correspondingly inclined forward to form the rear support of the plane-bit which has bearing upon them. The distance between the two ribs corresponds to the width of the end of the arm O, of the laterally adjusting lever, so that when the bit is set in place, the lower end of the arm O, will stand in the recess between the two ribs P P so that these ribs will form a fulcrum, upon which the lever may swing to the right or left, and as the lever is so swung, as indicated in broken lines Fig. 3, the fulcrum end of the arm O, being held fast in the recess between the ribs P P, it follows that the pivot L, will be moved accordingly, and that the end of the bit will be turned to the right or left, and such turning of the bit changes the parallelism of the edge of the bit with relation to the plane of the face of the stock.

When lateral adjustment is required to bring the edge of the bit into the proper parallelism with the plane of the stock, the laterally adjusting lever is turned accordingly, as before described. It is to be observed that the two levers by which the squaring of the bit is effected and the depth of the cut is gaged, respectively, act entirely independently of each other so that the operation of one does not affect the operation of the other, the two levers having independent connection with the bit.

By hanging the lever directly to the bit instead of to the stock, it maintains always the same position with relation to the bit; as the bit wears away the lever simply extends farther downward into the recess within which its lower arm O, works, and so that the bit cannot get beyond the control of the lever because of the wearing away of the bit, as by grinding, &c. The construction is simple and very effective.

As herein shown, the axis or horizontal pin I, on which the segment or lever H’, is hung, is located between the said ribs or posts P P in a vertical slot P’, formed midway of the length of a web P2, which joins the said posts or ribs with which it is made integral.

From the foregoing it will be understood that I do not claim broadly a bench-plane having the bit laterally adjustable, but I am aware that planes have been constructed with a lateral adjusting lever hung to the under side of the bit, and so as to take its fulcrum on the stock, but in such case it has been necessary to make the lever adjustable on the bit, whereas by constructing the stock with a longitudinal recess within which the end of the lever may work as a fulcrum, the permanent hanging of the lever to the bit is made practicable. I do not therefore wish to be understood as broadly claiming hanging the lateral adjusting lever directly to the bit.

What I do claim as my invention, and desire to secure by Letters Patent, is —

1. In a bench-plane, the combination with a stock constructed at its rear end with a central longitudinal recess, of a bit, and an adjusting-lever pivotally attached to the outer end of the same, and extending rearward to be grasped for manual operation, and forward and downward to enter between and engage with the parallel side walls of the said recess at different points in the length thereof according to the position of the bit in the plane-stock, the said walls forming points of purchase for the operation of the lever in squaring the bit in the stock, substantially as set forth, and whereby the lever is always preserved in its right relation to the bit, although the same must constantly be moved forward in the stock as it becomes shorter through wear and grinding.

2. In a bench plane, the combination with a stock constructed at its rear end with two vertical ribs or posts extending parallel with each other and with the stock, and having their upper ends forwardly inclined correspondingly; of a bit having its rear support upon the said inclined upper ends of the said ribs or posts, an adjusting-lever mounted in the stock for vertical movement, and engaging directly with the bit which it adjusts vertically, and an adjusting lever pivotally secured to the rear end of the said bit, and extending rearward for manual operation and forward to enter between and engage with the said ribs or posts at different points in the length thereof according to the position of the bit in the stock, the said ribs forming points of purchase for the operation of the lever in squaring the bit in the stock, substantially as set forth, and whereby the said lever last mentioned is always preserved in its right relation to the bit, although the same must be constantly moved forward in the stock as it becomes shorter through wear, and grinding, whereby also the two levers act on the bit independently of each other.

3. In a bench-plane the combination with a stock constructed at its rear end with two vertical ribs or posts parallel with each other and with the length of the stock, having their upper ends forwardly inclined correspondingly, and joined by a vertically slotted web which is located between them; of a bit having its lower face provided with a longitudinal rack and having its rear support upon the said posts; an adjusting lever pivotally secured to the outer end of the said bit to the rear of the said rack, and extending rearward for manual operation, and forward to enter between and engage with the said posts or ribs at different points in the length thereof according to the position of the bit in the said stock, the said ribs forming points of purchase for the operation of the lever in squaring the bit in the stock; a lever pivoted in the vertical slot formed in the web between the ribs, and taking at its forward end into the rack formed in the lower face of the bit; and means for adjusting the said lever up and down, substantially as set forth, and whereby the adjusting lever pivoted to the bit is always preserved in its right relation thereto, although the same must constantly be moved forward in the stock as it becomes shorter through wear and grinding.

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

To all whom it may concern:

Beit known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Plane-Irons, of which the following is a specification.

My invention relates to improvements in plane-irons; and the objects of my improvement are to facilitate the manufacture of the plane-iron, to improve its quality when made, and to make the plane-iron capable of being worn down farther than the old style of iron used in connection with certain planes.

In the accompanying drawings, Figure 1 is a side elevation of my plane-iron with cap-iron attached. Fig. 2 is a plan view of the under side of said plane-iron as laid upon the cap-iron, illustrating the manner of putting the two together; and Fig. 3 is a face view of the plane-iron in position upon the frog of the plane-stock and much worn, a portion of the plane-stock being shown in section.

The general form of the plane-iron B is the same as that in ordinary use, and the cap-iron C, with its large-headed holding-screw D, is also of ordinary construction. I provide the plane-iron B with a longitudinal slot 4, through which the body of the holding-screw D passes in holding the cap-iron upon the plane-iron and permitting the cap-iron to be adjusted up and down thereon. Instead of making the enlargement to let pass the head of the screw D, at the upper end of the plane-iron, as in the ordinary plane, I form said circular enlargement 5, at the end of the slot 4, which is nearest the cutting-edge 6. This enlargement comes so near the cutting-edge that when the screw is in the enlargement and the cap-iron and plane-iron have their edges parallel to each other, the cap-iron will project considerably over the cutting-edge. If the two parts should be held in this position when the head of the screw is being passed through the enlargement 5, in order to assemble the plane-iron and cap-iron, and then the cap-iron should be drawn upwardly to bring the screw into the slot the cap-iron would be liable to strike the cutting-edge and dull it. Instead of assembling the parts in this manner, the cap-iron and plane-iron should be held at right angles to each other and the screw-head passed through the enlargement 5, as shown in Fig. 2. The cap-iron may then be drawn upward to the upper part of the plane-iron to bring its screw into the slot and the cap-iron then turned around and secured in position, as shown in Fig. 1.

In Fig. 3 I have illustrated the plane-iron as nearly worn out by repeatedly grinding off its edge, and I have shown the same in connection with a plane-stock E, its frog F, and a laterally-adjusting lever G, having a roller 7, that projects and enters the slot 4; in the plane-iron for adjusting the same laterally. 8 designates the upper end of the lever that takes into the cap-iron for adjusting the plane-iron endwise, all as in ordinary planes; but in said figure the cap-iron is not shown, in order to better show the friction-roller 7 of the laterally-adjusting lever as it lies in the slot of the plane-iron. It will be seen that this friction-roller is still some distance from the upper end of the slot and that it may still properly engage the plane-iron until the latter is worn much shorter than shown, and so short as to wear into the circular enlargement 5 at the lower end of the slot. I have also shown in Fig. 3 in broken lines, as at 9, the contour of the circular enlargement, which is ordinarily at the upper end of the plane-iron, and it will readily be seen that with such an enlargement at the upper end of the plane-iron the laterally-adjusting lever would be inoperative.

By my improvement I adapt the plane-iron to be worn down closer than in the ordinary plane-iron and to operate in connection with the laterally-adjusting lever until the plane-iron is completely worn cut. By making the circular enlargement at the end of the slot, which is nearest the cutting-edge, I am enabled to make the plane-irons by pressing them out from sheet-steel and to harden and temper them to a point up to or beyond the lower edge of this circular enlargement with less liability of cracking the plane-irons at this point, so that fewer irons are lost in hardening and tempering, and they are less liable to become cracked or broken at said point after they are put into use. This is because there are no angular notches at the lower end of the slot from which a crack will start, and because the slot opens into the circular enlargement, so that it is less liable to strain in the expansion and contraction of the metal during the hardening and tempering process. Care is generally taken in hardening the ordinary plane-bit not to harden it quite up to the slot ; but by my improvement such care is not necessary.

I claim as my invention —

In a plane, the combination of a plane-iron having a longitudinal slot 4 with the circular enlargement at its lower end, said slot extending up near to the upper end of the bit without any enlargement at said upper end, and a laterally-adjustilig lever having a projecting part fitted to work in the upper end of said slot, substantially as described, and for the purpose specified.

To all whom it may concern:

Be it known that I, CHARLES F. YOUNG, a citizen of the United States, residing at Birmingham, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Plane-Bit Fastenings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements in planes, but more particularly does it appertain to means for holding and securing together the bit and the cap-plate in such manner that while they may be easily and readily loosened for purposes of adjustment or the grinding of the bit, and may be, if necessary, completely detached, the accidental separation of the bit, the cap, and the fastening will be obviated; and with these ends in view my invention consists in the construction and combination of elements hereinafter fully explained, and then recited in the claims.

In order that those skilled in the art to which my invention appertains may fully understand its construction and operation, I will describe the same in detail, reference being had to the accompanying drawings, which forma part of this specification and in which —

Figure 1 is a plan view of a plane-bit and cap-iron secured together in accordance with my invention ; Fig. 2, a reverse plan view; Fig. 3, a central longitudinal section; Fig. 4, details showing the fastening.

Like numerals denote the same parts in all the figures.

1 is the bit, having a central longitudinal slot 2, which latter at one and preferably at both extremities is enlarged, as shown at 3.
4 is the cap-iron, of any usual construction, having such openings therein as are demanded by the construction of the plane to which it is to be applied. Near its center the cap-iron has swiveled therein a headed stud 5, between which and one side of the cap-iron is arranged a washer 6. The upper end of this stud bears two semicircular cam-faces or inclines 7, and the head upon which these inclines are formed is provided with a drive-slot, as seen at 8, or with a wrench-hole or other means whereby it may be turned.

The fastening-stud, as will be readily understood, while rotative relative to the cap-iron, is permanently affixed to it and therefore cannot become separated and lost.

In assembling the parts of my improvement one of the enlarged openings in the bit is dropped over the larger head of the stud, and it may then be moved longitudinally along the cap-iron to any desired position, the neck portion of the stud being of less diameter than the width of the slot 2. In thus moving the bit care should be taken that the high points of the inclines or cam-surfaces lie within the slot. When the bit and cap-plate are in the position desired, they may be secured together by the partial rotation of the stud, which as it is turned causes the inclines to ride up on the edges of the slot, and thereby bind the bit to the cap-plate. As only a partial turn of the stud is required to effect the tightening or loosening of the parts, the simplicity of the device is at once apparent, and as the stud is permanently aflixed to the cap-plate it cannot be lost or mislaid, as is liable to occur with the ordinary binding-screw heretofore in common use.

I claim —

l. The combination, with the bit slotted longitudinally, of the cap-iron and the stud swiveled to the latter and provided with the cam-surfaces adapted to engage the surface ot the plane-bit, substantially as described.

2. The combination, with the plane-bit provided with a longitudinal slot having a large opening at its extremity, of the cap-iron, a double-headed stud swiveled in said cap-iron and provided as to one head with semicircular inclined surfaces, and with means, as a drive-slot, for turning said stud, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, AUGUST FRÖMMING, a citizen of the United States, residing at Lanham, in the county of Washington and State of Kansas, have invented certain new and useful Improvements in Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved plane, which will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my new and improved plane. Fig. 2 is a central vertical sectional view of the same, and Fig. 3 is a perspective view showing the bit-iron separated from the plane-stock.

The same letters of reference indicate corresponding parts in all the figures.

The object of my invention is to provide a plane which will work to perfection and with ease and rapidity on rough boards and across the grain of lumber where the ordinary plane could not be used; and to this end my invention consists in the new and improved plane, which will be now described.

Referring to the several parts by letter, A indicates the wooden stock of my plane, this stock having formed in its lower side a recess A’, which is usually rectangular in shape, while in each side of the stock are formed the vertical recesses A2 A2.

The body B of the bit-iron is in the form of a solid block or thick plate adapted to fit adjustably in the recess A’ of the stock, and is formed at each side with the parallel upwardly-extending arms B2 B2, that fit movably in the side recesses A2 of the stock. These arms B2 are formed with the vertical slots A3, open at their upper ends, and set-screws C pass through these slotted arms and work in threaded apertures in re-enforcing plates D, which are let into the sides of the stock, as shown, and secured by small screws. The lower working-face of the bit-iron is formed with a series of numerous transverse parallel cutting-teeth B’, having the inclined rear sides, as shown, and it will be readily seen that when in use these numerous fine cutting-edges will work to perfection on rough boards or across the grain of lumber, cutting smoothly and evenly where it would be impossible to work at all with an ordinary plane. It will be further seen that the bit-iron can be adjusted in the recessed stock by loosening the set-screws C to cause the teeth or cutting-edges B’ to project down farther below the lower face of the plane-stock.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and advantages of my invention will be readily understood.

It will be seen that my new and improved plane is simple and strong in construction and exceedingly efficient in its operation. It will work perfectly on rough boards, across the grain of lumber, across knots, &c., and the bit-iron can be adjusted as required.

Having described my invention, what I claim, and desire to secure by Letters Patent, is —

1. The combination, in a plane, of a stock formed with the bottom recess A’ and the bit-iron block B, adapted to fit in the said recess and formed with the series of parallel cutting-teeth B’, extending transversely across the lower face of the block, substantially as set forth.

2. The combination of the stock A, formed with the bottom and side recesses, the bit-iron formed with the series of transverse cutting-teeth B’ and having the slotted side arms B2, and the set-screws C, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, HENRY CONDRON, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Plane-Bits, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in which —

Figure 1 is a perspective view of a plane-bit embodying the features of my invention. Fig. 2 is a front view of the same, and Fig. 3 is a central longitudinal sectional view thereof.

Like letters of reference in the different figures indicate like parts.

My invention relates to that class of plane-bits in which the chisel or cutting portion is made from a thin plate of steel supported by a back plate of inferior metal. This construction, while possessing many advantages, is subject to the objection that a considerable vibration thereof is produced in planing hard woods, which makes it impossible to produce satisfactory work with it.

The object of my invention is to overcome this objection by providing a supplemental clamp-plate, by which the thin chisel-plate is supported at the point of greatest strain, while the usual clamp-plate is retained to regulate the “bite” of the chisel; all of which is hereinafter more particularly described, and definitely pointed out in the claims.

Referring to the drawings, a represents the plane-chisel, which consists of a thin plate of steel, having the usual chisel-edge a’, Fig. 3.

b is the back plate, and c the usual front or clamping plate bent, as shown at c’, and having the usual thin tapered edge c2, as shown, which is intended to be adjusted near to the chisel-edge a’, according to the work to be done, said tapered edge of the clamping-plate being preferably below the end b’ of the back plate b.

The chisel, back plate, and clamp-plate are attached to each other by means of the usual clamp-screw d. It will be seen that a pressure upon the point a’ of the chisel tends to bend said chisel back over the edge b’ of the back plate, which forms a fulcrum therefor. To overcome this tendency, I interpose a supplemental clamp-plate e between the chisel a and clamp-plate c, which supplemental plate is bent at e’, and the edge of which bears upon the chisel-plate above the edge b’ of the back plate b and at the point of greatest vibration in said chisel-plate. It is obvious that upon clamping the respective plates together, as shown, by means of the clamp-screw, the pressure upon the chisel-plate a is as great above as below the lower end of the back plate. I have found in actual practice that all vibration of the chisel is thereby obviated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is —

1. The combination, in a plane-bit, of a chisel consisting of a thin plate of steel, a back plate, a clamp-plate having its edge below the edge of the back plate, and an interposed supplemental clamp-plate having its bearing edge upon the plane-chisel above the lower edge of the back plate, substantially as shown and described.

2. The combination, in a plane-bit, of the chisel a, back plate b, clamp-plate c, supplemental clamp-plate e, and a clamp-screw for holding the same in the respective positions with relation to each other, substantially as shown and described.

In testimony whereof I have signed this specification, in the presence of two subscribing witnesses, this 6th day of February, 1890.

To all whom it may concern:

Be it known that I, REINHARD T. TORKELSON, a citizen of the United States, and a resident of the city and county of Worcester, State of Massachusetts, have invented certain new and useful Improvements in Carpenters’ Planes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming a part of this specification, and in which —

Figure 1 represents a side view, partly in section, of a bench-plane embodying my improvements. Fig. 2 is a plan of the lower part of the cutter with my improved cap secured thereon, as hereinafter more fully described. Figs. 3 and 4 are transverse sections through said cutter and cap, taken on lines a and b in Fig. 2, respectively, looking in the direction of the arrow in said figure. Fig. 5 is a central longitudinal section through the cutter and cap, taken on line c, Fig. 2; and Fig. 6 is a perspective view of the detachable angle-plate employed for adjustably fastening the cap to the cutter, as hereinafter specified.

To enable those skilled in the art to which my invention appertains to better understand the nature and purpose thereof, I will now proceed to describe it more in detail.

My said invention relates to improvements upon the carpenter’s plane patented by O. R. Chaplin in the United States under date of May 7, 1872, No. 126,519; and it consists of improvements in the construction of the cutter and cap, as hereinafter set forth.

In the drawings, the part A represents the plane-stock; B, its handle; C, its knob for holding the front end of the plane; D, the cutter; E, the cap; F, the supporting-saddle, fastened at its lower end to the boss G, projecting up and backfrom the bottom of the stock.

H is the clamp, having the lugs d upon each side adapted to catch under the sides of the saddle.

I is the thumb-screw for operating said clamp.

J is a screw-cam fitted to turn on the stationary pin e.

K is a half-nut projecting down from the upper end of the saddle and engaging with said screw-cam, and L is a lever for operating through the screw-cam and half-nut the saddle and cutter longitudinally.

Any further description of the old parts of the plane may be obtained, if desired, by reference to the patent previously alluded to.

My improvements in the cutter and cap are as follows: Instead of fastening the cap E to the clamp H, as in said Chaplin patent, it is in this instance fastened to the cutter D by forming a transverse opening f in said cutter to receive a transverse angle-plate M, which is passed up through the cutter from the under side, so as to form a holding-loop above the cutter. Through said loop is passed the longitudinal tongue or blade g, formed on the cap E, whereby said cap is held in position. The tongue or blade is made curving or bow-shaped lengthwise, so as to produce a constant pressure upward against the holding angle-plate when it is slipped under the same, and the cap is also provided with two flanges h h, one at each side of the tongue or blade, curved downward, and bearing at their ends upon the top surface of the cutter, the purpose of the latter being to hold the edge j of the cap elevated above the cutter to prevent injury to the cutting-edge of said cutter in the operation of placing the cap in position thereon. Although said flanges h h are preferable for the above purpose, I do not limit myself thereto, as the same result may be obtained by forming the cap so as to bear upon the cutter in a similar manner at any suitable point between the sides or edges thereof, said modification consisting simply in changing the positions of said bearing-points. The same will be readily understood without special illustration in the drawings. The angle-plate is held in position in the cutter against the upward pressure produced by the spring tongue or blade g by means of ears or projections k k, formed upon each end thereof, adapted to bear upon and hold against the under side of the cutter. Said ears are preferably recessed into said cutter, as is shown in Fig. 4, so as to bring the bottoms of said plate and cutter flush with each other. It is also preferable to make the edges of the ears slightly beveled or inclined and the ends of the opening in the cutter correspondingly beveled, as is indicated at l l in Figs. 4 and 6, for the purpose of holding the angle-plate in the cutter after having been sprung into position therein when the cap is not fitted thereto. In practice only a slight bevel is required to effect the desired result. Consequently the plate may be easily sprung into position, as aforesaid. As so slight a bevel would not be perceptible in illustrating the same, I have shown quite a sharp bevel in the drawings, and considerably greater than would be employed in practice.

In fitting the cap to the cutter the angle-plate is first passed up through the opening in said cutter and forced into position, after which said cap is placed on the cutter and its spring tongue or blade g slipped up through the loop formed by the angle-plate projecting above the surface of the cutter. The cap is then adjusted accurately, as required, to govern the thickness of the shaving to be cut, when the cutter, with the cap thus adjusted and secured thereon, is placed in the plane and clamped in position, as in the Chaplin and other planes, by means of the clamp H and its thumb-screw.

Although my invention is more particularly designed to be used in the manufacture of planes whose stock is made of metal, it is equally applicable to other kinds of planes. By thus securing the cap to the cutter, as hereinbefore described, it will at once be manifest to those skilled in the art to which my invention appertains that said cap, being susceptible of adjustment to the cutter before fitting said cutter in position, renders said operation more easy to perform, and also admits of a more accurate adjustment than when said adjustment is made after the cutter has been placed in position. A construction whereby said result may be accomplished is the main purpose of this invention.

If desired, a holding-loop may be formed upon or secured to the cutter to take the place of the detachable angle-plate M. The construction described, however, is preferable.

What I claim as new, and desire to secure by Letters Patent, is —

1. A combined cutter and cap for carpenters’ planes, comprising, in combination, the cutter having a suitable transverse holding-loop above its top surface and the cap having a longitudinal spring tongue or blade adapted to be passed through said loop to hold the cap in position during and after adjustment upon the cutter preparatory to the application thereof to the plane, substantially as and for the purpose set forth.

2. The combination of the cutter D with the detachable angle-plate M, fitted transversely in a suitable opening therein, and the cap E, having the longitudinal spring tongue or blade g, adapted to be passed through the loop formed by said angle-plate when fitted in position in the cutter, substantially as and for the purpose set forth.

3. The combination of the cutter D with the detachable angle-plate M, fitted transversely in a suitable opening therein, and the cap E, having the supporting side flanges h hand the longitudinal spring tongue or blade g, the latter adapted to be passed through the loop formed by said angle-plate when iitted in position in the cutter, substantially as and for the purpose set forth.

4. In a bench-plane, the combination, with the cutter D, having a transverse opening with beveled sides, of the detachable angle-plate M, having flanges with the edges thereof beveled to correspond with the sides of the opening in the cutter, substantially as and for the purpose set forth.

5. In a bench-plane, the combination, with the cutter D, having a transverse opening with beveled sides, of the detachable angle-plate M, having flanges with the edges thereof beveled ito correspond with the sides of the opening in the cutter and the tongue or blade of cap E, substantially as and for the purpose set forth.

6. The combination of the stock, saddle, and clamp device of a bench-plane with the cutter D, provided with a transverse loop above its top surface, and the cap E, having the supporting-flanges h h, and the tongue or blade g, the latter adapted to be passed through said loop to hold the cap upon the cutter during and after adjustment preparatory to the application thereof to the plane, substantially as and for the purpose set forth.

To all whom it may concern:

Be it known that I, WILLIAM STEVENSON, of Douglas Flat, Calaveras county, State of California, have invented an Improvement in Combination-Planes; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to the class of planes in which blades of different character are combined in the same stock; and my invention consists in the novel stock, the double-ended blades and their manner of arrangement, and means for adjusting them in the stock, as I shall hereinafter more fully describe.

The object of my invention is to provide a plane of simple construction, and which, by reason of its different blades, is adapted for several uses.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a perspective view of my combination-plane. Fig. 2 is a top view of same. Fig. 3 is a side elevation of the stock, the securing-plate d being removed to show the blade and its operative mechanism.

A is the stock of the plane, having its upper and lower edges made with central longitudinal guides, a, thus dividing it into four working-surfaces, one being on each side of the central guide of each edge. These surfaces in any given stock may be made in the proper shape or contour to suit the several uses intended for that particular combination-tool. In the present instance, in order to illustrate this fully, I have shown two of the surfaces — one on each edge and on the same side of the guides a — as “matching” surfaces — that is, one is for a “tongue” and the other is for a “groove.” The remaining two surfaces I show as a simple “nosing” surface and a “molding” surface. I do not confine myself to them, however, for my invention contemplates the making of any suitable surfaces, the essential feature of the stock in this respect being its construction, providing for any four working-surfaces.

In each side of the stock are made two throat-sockets, B, which are arranged in reversed position with relation to each other, and also in each side of the stock is made a groove-seat, C, opening at each end into one of the working-surfaces and near each end into a throat-socket. Into these grooves C are fitted the blade-guides D, which are secured in place by plates d, let in flush with the sides of the stock and secured thereto by screws d’. Fitted in one side of each of these blade-guides is a rotary pin, e, which carries a pinion, E, the teeth of which project into the guide far enough to engage the rack-teeth of the blades, as I shall presently explain.

Upon the outer end of each pin e (which projects through the securing-plate d) is fixed a lever-arm, F, having at one end a small thumb-piece, f, by which it may readily be turned to turn the pin axially and rotate the pinion, and in the other end said lever-arm carries a set-screw, f’, the lower end of which is made to come in contact with the plate d, whereby the arm may be firmly set in the position to which it may be turned, thus holding the pinion rigidly.

G are the bits. I have shown two. Each is a double-ender-that is to say, a cutting-edge is made on each end. I do not confine myself to the particular shape or character shown on these planes, for they are made to adapt them to the uses intended and corresponding to the working-surfaces of the particular stock they are designed to fit. In this case I have shown a matching-edge on each end of one of the bits, and on the other I have shawn a nosing-edge on one end and a molding-edge on the other end. There are therefore four edges in the set. Each of these bits is formed or provided with rack-teeth g. These bits are fitted through the guides D, so that their rack-teeth are engaged by the pinion E, and their edges extend through the ends of the groove-seats C into proper position along the working-surfaces of the stock. They are made of such a length that when the edge on one end is projected for proper operation in connection with its working-surface the edge on the other end is withdrawn from its working-surface, so as not to be in the way when handling the tool.

The operation is as follows: When I wish to use the grooving-edge, I turn the lever-arm F by the thumb-piece f in a direction and to an extent sufficient to cause the pinion E to project said edge to working position, (the edge on the other end being withdrawn out of the way by the same movement,) and I then fix it in position by setting the screw f’. The operation is the same with any of the other edges.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is —

1. In a combination-plane, a bit having a cutting-edge on each end and having rack-teeth formed on one of its sides, substantially as herein described.

2. In a combination-plane, a stock having a working-surface on its upper and lower edges, in combination with a bit fitted to the stock and having a cutting-edge on each end, and an adjusting device for operating the bit, so that when its cutting-edge on one end is projected into position along its corresponding working-surface the cutting-edge on its other end is withdrawn from its working-surface, substantially as herein described.

3. In a combination-plane, a stock having a working-surface on its upper and lower edges, in combination with a bit fitted to the stock and having a cutting-edge on each end and rack-teeth on its side, and the mechanism for adjusting the bit, as described, consisting of a rotary pin and a pinion carried thereby and engaging the rack-teeth of the bit, substantially as herein described.

4. In a combination-plane, a stock having a working-surface on its upper and lower edges, in combination with a bit fitted to the stock and having a cutting-edge on each end and rack-teeth on its side, and the mechanism for adjusting the bit, as described, and holding it when adjusted, consisting of the rotary pin, the pinion on the pin engaging the rack-teeth of the bit, the lever-arm on the pin, and the set-screw in the lever-arm, substantially as herein described.

5. In a combination-plane, a stock having a working-surface on its upper and lower edges, the bit-guide let into the side of the stock, and the plate screwed to the stock for holding the guide, in combination with a bit fitted in the guide and having a cutting-edge on each end and rack-teeth on its side, and the mechanism tor adjusting the bit, as described, and holding it when adjusted, consisting of the rotary pin in the side of the guide, the pinion on the pin engaging the rack-teeth of the bit, the lever-arm on the outer end of the pin, and the set-screw in the lever-arm, substantially as herein described.

In witness whereof I have hereunto set my hand.

_________________

To all whom it may concern:

Be it known that I, WILLIAM F. KELLETT, a citizen of the United States, and residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Plane-Bits, which is fully set forth in the following specification, reference being had to the accompanying drawings, in which —

Figure 1 is a plan view of a plane-bit containing my iniprovement with the base A uppermost. Fig. 2 is a plan view of the same with the cap B uppermost. Fig. 3 is a plan view of the base A. Fig. 4 is a plan view of the chisel or planing-knife. Fig. 5 is a detail section of same on line x x, Fig. 4. Fig. 6 is a detail section taken on line y y, Fig. 2. Fig.
7 is a section taken on line z z, Fig. 2.

My improvement relates to that class of planing-tools known as “hand-planes,” and particularly to the parts known as the “plane irons.”

In the drawings, A is the base or holder; B, the cap; C, the chisel or planing-knife; D and E, set-screws.

In the general manufacture of planes by the old method the base or holder A is made of expensive steel, because it also has to serve the purpose of the chisel or planing-knife, and it is necessarily quite heavy in order to give it the requisite rigidity or stiffness.

In the manufacture of a plane containing my improvement the base A and cap B can be made of iron or cheap steel inasmuch as they carry no knife-edges and perform no other function than that of a clamp or vise which holds the chisel C in proper adjustment to the rest of the plane. The chisel C is made of the best quality of saw-plate or other line sheet-steel, and is fastened to the base or holder A by any proper device. I have provided for this purpose the set-screw D and nut G, and set-screw E, and cap B. The set-screw D passes through a suitable hole, w, in the chisel C, and runs in the slot n in the holder or base A. The set-screw E plays in the slot o of the base A, and passing through the slot s in the chisel C screws in the threaded hole r in the cap B.

When it is desired to sharpen. the chisel, the set-screw E and the nut G are released, and the chisel C is moved forward. When the sharpening has been completed, the chisel is moved into proper adjustment and the set-screws are tightened.

The chisel C is made of thin non-self-supporting material, and could not be used alone, but must be supported by some means similar to the systems of irons which I use. It is designed to perform no function save that of a chisel or cutter. The lower end of the base is lipped or turned up, and the lower end of the cap is lipped or turned down, so as to come together and make a snug joint in which to hold the lower end of the chisel.

In putting the parts together of course it is understood that the cap B is uppermost when the chisel is in the plane, and the chisel C and base A would be placed accordingly for the purpose of best fulfilling their several functions. In practice, I so adjust the chisel C relatively to the base A that the bevel of the cutting-edge of the chisel forms a continuous surface with the bevel of the lower edge of the base, this being the most effective position of the parts.

Planes thus made will be less expensive and more easily adjusted and sharpened than those made after the old fashion. When the plane-bit is being set in the plane it is customary to strike the upper end of the base A with a hammer for the purpose of driving down the chisel. I have therefore provided a cap, K, which is made somewhat in the shape of a greatly-broadened old-fashioned wooden clothes-pin, and which, coming down over the end of the base A is riveted to it by the rivets a a. This cap receives the hammer-blows, and thus protects the end which without this protection would be upset and battered down. The cap can be easily removed and replaced at trifling expense. This cap may be applied to plane-irons made in the old way.

I am aware of the patent to Seely and Locke, No. 24,335, June 7, 1859, and do not wish to be understood as claiming the construction therein shown and described; nor do I wish to be understood as claiming, broadly, a plane-bit clamped between a cap and base or back plate, as said construction is old.

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

1. The combination, with the base plate having the thin steel chisel adjustably connected therewith, the adjacent surfaces of the two being plane surfaces, of the cap connected with the base-plate by a clamp-screw to clamp the chisel rigidly against the back plate, substantially as and for the purposes specified.

2. The combination, with the slotted base-plate, of the chisel connected therewith by a clamp-screw at its upper end, whereby the chisel may be adjusted longitudinally on the base-plate, and of the cap connected with the base-plate by a clamp-screw, whereby the chisel may be firmly clamped against the base-plate, when so adjusted, substantially as and for the purposes specified.

3. The cornbination, with the base A, chisel C, and cap B, provided with the slots o n s, and holes r w, of the set-screw E, and set-screw D, and nut G, substantially as and for the purposes set forth.

4. The combination, with the base A, of the cap K, substantially as and for the purposes set forth.

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 and State of Connecticut, have invented certain new and useful Improvements in Stops for the Cutters of Matching-Planes, of which the following is a specification.

My invention relates to improvements in stops for the cutters of matching-planes; and the object of my invention is to furnish a convenient and inexpensive means for limiting the aggregate depth of cut. I attain this object by the simple construction illustrated in the accompanying drawings, in which —

Figure I is a plan view of my improved stop and the cutter to which it is attached. Fig. 2 is a side or edge view of the same, and Fig. 3 is a reverse plan view thereof.

I make the cutter A of substantially the usual form, except that I make its shank narrower than the end of the cutting-bit, in order to adapt the cutter for use in a two-part stock, in the manner fully described in an accompanying application of even date herewith.

Within the slot in the middle of the cutter I arrange a depth-stop, a, the same being narrow enough to pass through said slot. This stop a is in the form of an angle-piece, with its back or shank b of a width greater than the slot in the end of the cutter. The angle at which the bottom of the stop and its shank stand to each other is such that when the shank rests upon the back of the cutter and the cutter is set at the angle of inclination that it will bear when properly seated within the stock, the body of the stock a will be substantially in a horizontal position, as shown in Fig. 2. I hold the stop in place by means of an adjusting-screw, c, which passes through the slot in the cutter into a threaded hole in the shank b of the stop. This screw may have a head large enough to cover the slot in the cutter; but I prefer to place a washer under the head of the screw, as shown. By loosening the screw the stop a may be slipped up and down in the slot of the cutter, so as to bring its under surface at any desired distance from the cutting-edge of said cutter, the slot therein being made long enough to permit of said adjustment. When so adjusted, the screw may be tightened to hold the stop in place. As the cutting-edge upon either side of the slot is brought into action to form a tongue, the tongue extends up into the slot in the cutter. After repeated cuts, the stop a bears upon the edge of the tongue, to limit the depth of the cut, and consequently the extent that the tongue shall project from the shoulders formed on the edge of a board by means of said cutter. It will thus be seen that by the term “depth-stop” I mean a stop for limiting the extent which the plane is capable of cutting by repeated strokes, in contradistinction to the depth of a single cut, (the thickness of the shaving,) which is governed by the extent that the edge of the cutter projects from the bottom of the stock and by the width of the throat in said stock. By thus arranging the stop within the slot of the cutter and providing it with suitable means for permitting of its adjustment and holding it upon the cutter, I provide a depth-stop which is not only convenient to adjust and use, but it may always remain upon the cutter, so that it will not become lost, and so that a change in the adjustment is not necessitated every time the cutter is removed from the stock.

I am aware that matching-planes have heretoforebeen made in which an adjustable depth-stop has been secured to the stock, and I hereby disclaim the same.

I claim as my invention —

A stop to regulate the aggregate depth of cut, attached directly to the cutter of a matching-plane, with the body of the stop within the slot of the cutter, substantially as described, and for the purpose specified.

Specification forming part of Letters Patent No. 221,763, dated November 18, 1879; application filed September 15, 1879.

_________________

To all whom it may concern:

Be it known that I, JOHN W. AMMONS, of Columbia, in the county of Boone and State of Missouri, have invented a new and Improved Grooving-Iron, of which the following is a specification.

My invention relates to improvements in the tongued irons or bits used in grooving-planes.

Heretofore the form of these irons has been such as to leave the corners of the groove sharp. This is objectionable on account of their liability to break off when the tongue is forced in and carried back into the groove, whence they have to be removed at a great expense of time and trouble; or if allowed to remain they interfere with the making of a good joint. To prevent this with the present tools, it is the habit of many workmen to chamfer off the corners with an ordinary rabbeting-plane; but this requires the use of another tool and the expenditure of valuable time.

The object of my invention is to provide a plane-iron which will chamfer off the outer corners of the groove simultaneously with the planing of the groove.

The invention consists in a plate with beveled cutting-edges, a slot, and a longitudinal groove, in combination with a grooving-iron provided with a cutting-edge, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation of my improved iron. Fig. 2 is a plan view of the same. Fig. 3 is a cross-section on line x x of Fig. 2; and Fig. 4 represents, in perspective, a modified construction of the iron.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the grooving bit or iron, made of a rectangular bar of steel, with cutting-edge B. On the upper side of iron A is placed a flat plate of steel, C, which is secured to the bit by a set-screw, b, passed down through the slot c in the plate into a threaded hole in the bit.

In the under side of the plate is a shallow longitudinal groove, d, sufliciently wide to receive the bit, as shown in Fig. 3. This groove d, together with the set-screw b, connects the plate C rigidly with the bit A, so that the plate C can neither rise nor lose its parallel adjustment with relation to the bit.

At the lower end of plate C the corners are chamfered or beveled off at any suitable angle, and the corners are given sharp cutting-edges e e.

The plate C is designed to extend one-sixteenth of an inch beyond the sides of the bit, so that the angular cutting-edges e e will come in contact with the sides of the groove cut by the bit. The object of this arrangement is to chamfer off the upper corners of the sides of the grooves at the same time the groove is planed, so as to enable the flooring-tongue to be entered into the groove without trouble, and without liability of breaking off the corners of the groove and forcing the splinters in the groove, as before mentioned.

The lower end of plate C forms the shoulders of the plane-iron to limit the depth of the groove.

In Fig. 4 is shown a bit with the shoulders forming a part thereof, in the usual manner. Herein the front lower edges, f f, are cut off at an angle and sharpened to an edge, the same as the edges e e of the plate C.

Both forms of plane-irons operate in the same way to chamfer off the corners of the sides of the groove; but the arrangement first described offers superior facilities for keeping the bit in good order, on account of the ease with which the edges e e can be sharpened.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent —

The plate C, having beveled cutting-edges e e at a suitable angle, and provided with a longitudinal groove, d, and slot c, and set-screw b, in combination with the grooving-iron having cutting-edge B, for the purpose of chamfering off the corners of the sides of the grooves, substantially as described.

To all whom it may concern:

Be it known that I, CHARLOTTE SMITH, of Chelsea, Suffolk, State of Massachusetts, administratrix of the estate of my deceased husband, JOHN FRANCIS SMITH, of said city, county, and State, do declare that the said deceased, during his lifetime, did invent a new and useful Plane-Iron Cap, of which the following is a specification:

The nature of the invention is that of a plate of metal of peculiar form, detachable, but when in use fastened by a peculiar device to one side of a plane-iron, being an improvement on the well-known plane-iron top of a carpenter’s plane; and the object of the improvement is to effect the ready removal of the top when required, and also the firmer holding it in place when in use.

Figure 1 is a view of one side of the plane-iron, showing the nut used to fasten the top, and the necessary slot in the plane-iron, &c. Fig. 2 is a vertical cross-section, giving the relative positions of the plane-iron, the top with its screw, and the nut of the same.

In the drawings, A, Figs. 1 and 2, is the plane-iron or blade of a carpenter’s plane. B, Fig. 1, is a slot in the same, of any convenient length or width, running lengthwise of the plane-iron. C, Figs. 1 and 2, is a nut, with a projection each side of it, (seen in Fig. 1,) forming a thumb-screw, a, being worked by the thumb and finger, screwed onto the screw D, Figs. 1 and 2, which screw passes through the slot B, Fig. 1, as seen in Fig. 2, and at the right-hand side in Fig. 2 is attached to the plane-iron top E, Fig. 2. A shoulder (seen in both figures, in dashed lines in Fig. 2) is attached to the base of the screw D, and also to the top E, and is cut away (see Fig. 1) on each side of the screw D, so as to enter into the slot B.

The inner surface of the top E is seen in Fig. 2 not to lie flat on the plane-iron, but to rest on the same by its ends, which are both, in the same figure, seen to be curved. The thinness of the top E, with the two curves noted, makes of it a spring of greater or less strength, as the thickness of the top E may vary.

It is not proposed to confine ourselves to any particular thickness of the top, nor to any particular curve of the ends. A circular enlargement is sometimes made of the slot B near one or the other end; but this is not claimed here as original.

The length of the shoulder portion left on entering into the slot B may be varied. The whole device of the top and its attachment may be adapted to any plane-iron, the size of the thumb-screw being varied to suit the width of th slot which may be borne by the plane-iron.

Operation: The parts of the device being in place, as seen in the drawings, the nut C is turned by the thumb and finger, thus bending, more or less, the top E and pressing the curved ends more tightly on the plane-iron. When the top E is to be removed there is no loss of time in searching for a screw-driver; but the thumb-screw C is readily turned by the thumb and finger, as before, and the top E is at once loosened; and if the slot B is cut as drawn in Fig. 1, the thumb-screw C is removed, when the top E is readily removed to admit the sharpening of the cutting-edge of the plane-iron.

If the circular enlargement referred to as optionally provided is present, the nut need not be removed, the thumb-screw arms in that case passing through the slot B.

I do not claim the providing the top with a single curved end.

I claim for the inventor —

1. The double curved plane-iron top shown, in combination with the plane-iron, the shoulder, the screw D, and a nut, all when constructed and fitted for use, substantially as described and shown.

2. The combination of the thumb-screw with its arms, the screw D, the shoulder seen, a plane-iron, and a plane-iron top, all when constructed and arranged substantially as described and shown.

Admimistratrar of John Francis Smith.

To all whom it may concern:

Be it known that I, GEORGE GOCHER, of Johnstown, in the county of Cambria, and State of Pennsylvania, have invented certain new and useful Improvements in Bead-Planes; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in bead-planes; and it consists in a bit which has a bead running its entire length, and the devices by which the bit is secured to the stock, all of which will be more fully described hereinafter.

The accompanying drawings represent my invention. a represents the stock, which may be of the form here shown, or any other that may be preferred, and which has its lower edge so formed as to cut beads, or any other form of surface that may be preferred. Just in the rear of the opening through the lower edge of the stock, through which the end of the bit passes, is formed the inclined plane c, the top edge of which is shaped so as to fit the under side of the bit which rests upon it. Pivoted to the side of the stock is a clamp, d, which is pressed down upon the top of the bit by means of a set-screw, e. thereby serving to hold the bit in any position in which it may be clamped.

The bit i is made of a thin sheet of steel of even temper throughout, rolled or otherwise formed so as to correspond to the bead or other form of work required. As the groove is made in the under side of the bit its entire length, as soon as it becomes dull it is only necessary to remove it and sharpen it as they would any other tool, without the trouble of drawing its temper or having to form the groove, whereby a great deal of time and trouble is saved. By thus forming the bit, not only for this but other kinds of work, they can be made much more cheaply and can be used their entire length.

I am aware that a cutter-head for planing-machines, having circular beveled cutting edge, is not new, and this I disclaim. My invention is confined to bits for planes alone. and whereby the bit can he readily and easily sharpened and used its entire length as it wears away.

Having thus described my invention, I claim —

The combination of a bit, i, made from a single sheet of metal, and having a bead rolled its entire length, with the stock a, having the inclines c and clamp d, and a set-screw, e, substantially as specified.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of January, 1877.

_________________

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Devices for Adjusting Plane Irons, of which the following is a specification:

My invention consists in the employment, in a plane-stock, of a revolving handle provided with a scroll-thread upon its face, all as hereinafter described:

In the accompanying drawing, Figure 1 is a central longitudinal section of a plane, showing an adjusting device which embodies my invention. Fig. 2 is a plan view of detached parts thereof, showing the frog and scroll-thread.

The stock A and handle B may be of any ordinary construction, and either of wood or iron. The cap-plate C and plane-iron D, together with the fastening device E, may also be of any construction now known. Upon an arm, a, or other support secured. to the body of the stock A, I place a revolving handle, b, the edge of which is made ina convenient form to be rotated by hand, and the upper face of which is provided with a scroll-thread, c. This revolving handle and scroll is so secured to the stock; that its face will be nearly in line with the face of the frog d, which supports the plane-iron. I form a lug, g, on the cap-plate C, which projects downward, and through the slot in the plane-iron D. The plane-iron and its cap-plate are secured together by the screw it in the ordinary manner, so that both move together. The lug g is so placed in the cap-plate that when in position for use, as shown in Fig. 1, it engages with the scroll-thread c.

By rotating the handle b in one direction the lug g will be thrown toward the outer end of the scroll, and it will carry the cap-plate and plane-iron with it, and draw them into the stock A. By reversing the movement of the scroll-thread the lug and plane-iron are carried in the opposite direction, whereby any desired adjustment of the plane-iron may be effected.

I have herein described the lug g as set in the cap-plate C; but it is evident that the result would be the same in case the lug g were set in the plane-iron D, and that more than one lug might be employed, if desired.

What I claim as my invention, and desire to secure by Letters Patent, is —

ln a plane-stock, the revolving handle b, provided with a scroll-thread, c, upon its face, constructed and operating substantially as described, and for the purposes set forth.

Specification forming part of Letters Patent No. 181,649, dated August 29, 1876; application filed April 29, 1876.

_________________

To all whom it may concern:

Be it known that I, HENRY DISSTON, of Philadelphia, Pennsylvania, have invented certain Improvements in Plane-Irons, of which the following is a specification:

The object of my invention is to so construct a plane-bit that it may be more readily and truly ground and sharpened than ordinary edge-tools of this class, a further object of my invention being economy in the consumption of material in making the tools.

In the accompanying drawing, Figure 1 represents a front view of a plane-bit made according to my invention; Fig. 2, a section on the line 1 2; Fig. 3, a transverse section on the line 3 4; Fig. 4, a modification of Fig. 3.

The plane-bit A (shown in Figs. 1, 2, and 3) has a series of parallel grooves or indentations, a, on that side from which the tool is beveled to a sharp edge, the grooves being of such a depth that they will extend into the beveled portion d, as shown. With the exception of these grooves or indentations the plane bit is similar to those of ordinary construction; and, as it is no thicker than usual, the ribs between the grooves impart the desired rigidity, While less material is consumed an its manufacture than in making common bits.

The grinding of the beveled edge of a bit thus constructed can be more readily accomplished than that of an ordinary bit, for the reason that there is less metal to remove, and it is much easier to grind truly an indented surface than one without grooves, as will be readily understood by those familiar with grinding operations.

The plane-bit can be readily manufactured by means of two dies, one being flat, for the flat face of the bit, the other having ribs corresponding with the desired indentations, and the two dies being used in connection with any ordinary drop press.

It is not essential that the indentations or grooves and intervening ribs should be of the precise shape shown in the sectional view, Fig. 3. They may, for instance, be of the form shown in Fig. 4, with good results as regards the facility of grinding, sharpening, and economizing of material.

I claim as my invention —

As a new article of manufacture, a plane-bit having grooves or indentations on its beveled side, as specified.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.

HENRY DISSTON.
