To all whom it may concern:

Be it known that l, WILLIAM E. SPAKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more particularly to a novel construction of sheet metal planes.

Certain features of my improvements are especially applicable to planes of the smaller sizes which are known as pocket planes or toy planes, but the invention is not limited in this particular.

The primary object which I have in view is the provision of a light, handy, efficient and durable plane, in which the number of parts is reduced to a minimum, and which can be readily and cheaply manufactured.

To this and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a plane embodying my improvements, Fig. 2 is a top plan view of the same, Fig. 3 is a section on line 3–3 of Fig. 2, Fig. 11 is a front end elevation of the plane, Fig. 5 is a rear end elevation thereof, Fig. 6 is a section on line 6–6 of Fig. 1, Fig. 7 is a top plan view of the frog, detached, Fig. 8 is a top plan view of the clamp, and Fig. 9 is a bottom plan view of the clamp.

Referring to the drawing, the body or stock 10 is of the usual channeled form and it is preferably constructed of sheet metal. The frog 11 has the usual relation with respect to the throat 12 and said frog is constructed of a sheet metal plate 11a having downturned side portions 11b fitted within and against the side walls of the stock. In order to secure the frog firmly in place in the stock, it is necessary to employ only two fastening members such as the rivets 13, 14. These rivets pass through the extensions 11b of the frog into and through the respective side walls of the stock. It will be noted from a comparison of Figs. 1 and 3 that the rivets 13, 14 are out of line with each other whereby any turning or rotary movement of the frog relatively to the stock is absolutely prevented simply by the use of these two fastening members, one associated with each of the side walls of the stock.

At the rear of the frog the same is provided with integral downturned lugs 15, 16 provided with threaded perforations for the shank 17 of the adjusting screw 18. The cutter or bit 19 is supported on the frog 11 in the usual manner and it is of customary form except for the fact that its rear extremity is provided with a transverse slot 20 to receive the milled head 21 of the adjusting screw 18. The peripheral portion of the head 21 extends through the slot 20 for a slight distance, and as the adjusting screw is turned, the head thereof will turn freely in the slot 20 thereby advancing or retracting the cutter 19 according to the direction in which the screw is rotated. ln other words, the slot 20 in fitting over the head 21 interlocks the cutter and the adjusting screw against relative longitudinal displacement while permitting the rotation of the screw relatively to the cutter.

The frog 11 carries a pivot or stud 22, and the cutter is provided with the usual slot to fit over this stud 22. The clamp 23 consists of a sheet metal plate having downturned edges 24 and a keyhole slot 25 adapted to cooperate with the stud 22 in the usual manner. At the rear extremity of the clamp 23, the same is provided with a threaded socket 26 through which a clamping screw 27 passes into engagement with the upper surface of the cutter or bit. The cooperation between the clamping screw 27, the clamp 23, the stud 22, and the bit 19 is more or less usual and need not be further described.

In order to afford a convenient and handy grip for the workman, the stock is provided at the rear end with a palm rest 28. This consists of an upwardly directed sheet metal plate having a convex rear surface and forwardly extending lugs 29 fitting between and against the side walls of the stock. The palm rest is substantially U-shaped in cross-section, the upper edge 28a being rounded and the lower edge 28b straight and horizontal and fitting snugly against the top surface of the bed of the stock. The lugs or extensions 29 are secured to the side walls of the stock by rivets 30, 31 or similar fastening members. The rivets 30, 31 are offset from each other as in the case of the rivets 13, 14 so that turning movement of the palm rest relatively to the stock is absolutely prevented without the employment of additional fastening means, Preferably, the forwardly and upwardly curved plate 28 forming the palm rest is located at the rear extremity of the plane body or stock, and is spaced from the frog and cutter located at the intermediate part of the stock so that the adjusting screw may be located between the palm rest and cutter. The rear surface of the palm rest curves forwardly in order to fit the palm of the operator, and the form of the palm rest is such that it merges from a shallow U-shaped cross-section near the top into a deeper U-shaped cross section at the bottom where the forwardly directed extensions 29 are provided.

I do not claim herein the combination with a stock having upright side walls, of a frog comprising a sheet metal plate having integral downturned side members secured to the side walls of the stock, and integral downtnrned lugs for the bit adjusting screw, one of said lugs being struck out from the rear edge of the frog, and the other being struck out of an opening at the intermediate portion of the frog, as claimed in my co-pending application, Serial No. 778,083.

Without limiting myself to the construction shown, I claim:

1. In a plane, the combination of a stock having side walls presenting a channeled cross-section, a member fitting within the stock and having side walls abutting the respective first-named walls, and means of connection between each side wall of said member and the adjacent side wall of the stock, said two means of connection being located ont of line with each other; substantially as described.

2. In a plane, the combination of a stock having parallel side walls, a sheet metal member having bent-up extensions at the sides fitting within and against said side walls, and a rivet securing each of said extensions to the corresponding side wall of the stock, said rivets being out of line with each other; substantially as described.

3. In a plane, the combination of a stock having upright side walls, a palm rest composed of a plate resting at its lower edge on the bed of the stock and having forwardly directed extensions or lugs at the sides, and a rivet securing each extension or lug to the respective side walls of the stock, said rivets being out of line with each other; substantially as described.

In witness whereof, I have hereunto set my hand on the 5th day of July, 1913.

To all whom it may concern:

Be it known that I, ALBERT CARLSON, a subject of the Crown of Sweden, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Bench-Plane Guides, of which the following is a specification.

This invention relates to carpenters’ tools, and its object is to produce an attachment for bench-planes designed to guide the plane to cut at some given angle relatively to a plane of the work.

To this end my invention consists in the construction and combination of parts forming a bench-plane guide hereinafter more fully described, and particularly stated in the claims, reference being had to the accompanying drawing, in which;

Figure I is an end view, partly in section, of a bench-plane guide according to my invention, carrying a plane in position for work. Fig. II, is a righthand view of the said guide.

Let numeral 3 represent a carpenter’s bench, 4 a board laid thereon to have its edge beveled, and 5 a plane in position for work. I provide a block 6 with a plane face 7 to slide upon the work, a body 8 with a pivotal bolt 9 passing through the block 6, and a screw nut 10 to secure it rigidly to the block when set at the desired angle. A carrier 11 is pivoted at 12 to the body and provided with clips 13 to engage the plane 5 at a side edge 14, and thumb-screws 15 to rigidly secure the clips. This carrier comprises a pair of segments 16, one attached at each side of the body 8, and having arcs of teeth 17 concentric with the pivot 12. A sleeve 18 mounted on a screw-threaded arm 19 of the body, is shaped at 20 as a detent to engage the notches 17, and it is impelled into engagement therewith by a nut 21 that is threaded upon the screw 19. An annular groove 22 in the nut is engaged by a stud 23 which is screwed through the sleeve, whereby the backward turning of the nut withdraws the detent 20. The segment 16 may be stamped with figures indicating in degrees, the angle being formed on the work at that set. Or numerals may indicate the points where the detent is to be set to level boards to match together in forming posts of 6, 8, or 10 sides, or other forms desired.

By using the turnbolt 9 as a pivot the body 8 and carrier 11 may be set at a longitudinal pitch to fix the plane edge 24 either at rightangles with the edge of the work, or obliquely thereto when it is desired to give a peeling cut. The sleeve 18 has a tang 27 entering between the segments 16 to keep it from turning with the nut 21. Rivets 28 are shown as means for attaching portions of the carrier together. The block 6 may be of any suitable material. By seizing the handle 25 with one hand and the knob 26 on body 8, with the other hand this device may be operated with ease, producing accurate work without requiring repeated trials to fit the bevel-square. It is reliable and inexpensive.

I claim:

I. In a bench plane guide, a block having a plane face to slide on; a carrier having means for securing a plane to it; a body member intermediate between the said block and carrier, this body member having pivotal connection with the said block, the line of the pivot being transverse to the line of travel of the plane, and the carrier having pivotal connection with the intermediate body member the line of the pivot being in the direction of the line of travel of the plane.

2. In a bench plane guide, a block to slide; a plane carrier, and an intermediate body pivotally connected with each, the pivots of the two connections being in lines at right angles to each other.

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

ALBERT CARLSON.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States of America, residing at New Britain, Connecticut, have invented a new and useful Plane, of which the following is a specification.

My present invention relates to planes and has for its general objects to provide a practical and inexpensive form of plane which can be used for a number of purposes and which will therefore take the place of a plurality of planes usually employed for such special purposes.

Other objects are to increase the solidity and strength of the same and to make it easily regulatable or adjustable to meet the different conditions.

In the accomplishment of the foregoing and other objects I construct a plane in two parts and mount the cutter blade on the forward end of the rearward section so that when the front part or section is removed the cutter will be left exposed and therefore adapt the rearward section for working in corners, etc. The two sections are rigidly united but so as to permit quick separation of the parts.

A special feature of the invention is the provision of a handle arch on one of the members having a seat or platform with which the other member is engaged, said arch being of reduced width at a point above the cutter seat to accommodate the shank of a cutter and a shank and a cap which has bearing against the under side of the arch.

Other features and details of construction will appear as the specification proceeds.

In the accompanying drawing I have illustrated my invention embodied in a concrete and practical form but it will be understood that changes and modifications may be made without departing from the true spirit and scope of the invention.

In this drawing: Figure 1 is a perspective view of a plane constructed in accordance with and embodying the invention. Fig. 2 is a broken plan view of the same. Fig. 3 is a broken side view of the rear or main body section of the plane.

Referring to the drawing more in detail: 7 designates the rearward main body portion of the plane and 8 designates the forward member or section of the plane, said sections being shown as having plain under surfaces 9 alining to form the bottom of the plane and plain side faces 10 disposed at right angles to the bottom. The two body members are rigidly secured together in a manner to permit of their ready separation by providing a rearward section having a platform 11 on its opposite end to receive a rearwardly projecting lug or supporting portion 12 on the forward section, relative lateral movement of the two members being avoided by providing the forward section with shoulders 13 at the opposite ends of the supporting lug arranged to bear against shoulders 14 at the opposite ends of the platform on the rear member, a single screw 15 sufficing with this construction to rigidly and positively secure the two parts together.

The rearward section is made preferably with an arch 16 extending rearwardly and downwardly from the platform to constitute a handle and guard for parts housed therein and this arch is preferably reduced in width at 17 at a point below the platform to provide clearance for the cutter and the cutter holding cap.

The cutter is designated 18, the same being shown in the form of a blade supported on an inclined seat 19 on the forward end of the rearward plane section, the cutting edge of said cutter extending down through a slot 20 provided between the adjoining ends of the front and rear sections. This slot usually extends through from one side to the opposite side of the plane and the cutting edge of the blade is preferably the full width of the plane. At a point in rear of the cutting edge the blade is narrowed or reduced in width as indicated at 21 so as to be received at the side of the reduced portion 17 of the arch.

22 designates the cap for holding the cutter blade in place, this cap being preferably, like the cutter, of substantially the full width at its forward end and reduced in width as indicated at 23 to form the rearward extending shank mounted on the side of the reduced portion of the arch, said cap being herein shown as a fulcrum 24 against the under side of the arch and carrying a clamping screw 25 at its rearward end bearing on the rearward portion of the blade shank.

A throat for the cuttings is provided by forming the rearward wall of the forward plane section with an upward and rearward flare or incline and the front end of the rearward section and the top of the cap with rearward flares or inclines 26 and 27 respectively.

Means for adjusting the blade are provided in the illustration and formed with a lever 28 pivoted at 29 on a post 30 mounted in the rear of the cutter seat and engaging the toothed under surface 31 of the cutter blade shank. The use of the plane is facilitated by providing a finger or thumb hold 32 on the forward plane section and this section usually also is provided with a suitable depth gage 33 and spurs 34. The rearward plane section usually mounts a fence 35 carried by an outstanding post 36 which can be attached to either side face of the plane. These several devices enable the tool being used as fillister plane and for various rabbeting purposes and the removal of the depth gage and fence permits of the tool being turned and operated at both sides for working in a corner, a “full width” blade in such cases permitting the tool to work down into the extreme corner.

The front plane section is readily removable and when removed leaves the cutter blade exposed on the front end of the rear section in which case said plane section may be used in the manner of a chisel to work in corners, etc. The general structure of the tool is such that the parts are all rigid and well braced when in use and in addition the structure is relatively simple and inexpensive to manufacture.

What I claim is:

In a plane, a rear body section having a cutter seat at its forward end, a platform above said cutter seat and a handle arch extending rearwardly from said platform to the rear end of the body section, a cutter mounted on the cutter seat, cutter adjusting means on said rear body section within said handle arch and protected thereby, a front body section having a rearwardly extending supporting lug bearing on the platform on the rear body section and a securing screw extending through said supporting lug into engagement with the platform.

CHRISTIAN BODMER.

To all whom it may concern:

Be it known that I, JOHN F. BRIDGES, citizen of the United States, residing at Alameda, in the county of Alameda and State of California, have invented certain new and useful Improvements in Bench-Planes, of which the following is a specification.

My invention relates to improvements in bench planes; and as its primary object contemplates a sectional plane wherein means is provided for vertically adjusting one of the said sections relatively to the blade to in this manner vary the depth of the cut and simultaneously enlarging or diminishing the chip throat.

A further object of the invention is to provide improved and simplified means for adjusting the blade relatively to the operating surface of the plane stock.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which :–

Figure 1 is a side elevation of a bench plane constructed in accordance with the present invention; Fig. 2 is a top plan view, partly broken away; Fig. 3 is a longitudinal sectional view of the plane as shown in Fig. 2; and Fig. 4 is a cross sectional view, the back face of the blades and bed plates being shown in elevation.

Referring now to the drawings by numerals, 1 and 2 designate respectively the plane sections, the said sections forming the stock or body of the tool. A partition 3 is formed integrally with plane section 2 at its forward end, the partition having formed integrally therewith a screw block 4. Angular extensions 5 are formed integrally with the plane section 2, the said extensions 5 being formed, one at each side of the said sections, and disposed to extend inwardly as shown to advantage in Fig. 2 whereby to form vertical grooves or guide ways 6 within which angular extensions 7 integral with a partition 8 of plane section 1 is fitted, this arrangement holding the said two sections together; preventing lateral and longitudinal movement of the said two sections; yet permitting, as will hereinafter appear, vertical adjustment of plane section 1 relatively to the said section 2 for the purpose of varying the depth of the cut made by the tool.

Partition 8 is enlarged at its base as indicated at 9, the enlargement having formed therein a threaded recess 10, said recess receiving the threaded shank 11 of an operating screw designated 12, said screw having a single spirally coiled thread adapted for engagement with the groove therefor in screw block 4. An opening 14 is formed in said partition 8, said opening providing an operating space for the said screw 12.

A suitable bed plate 15 is carried by plane section 2, the said plates being disposed at an angle of approximately 45° and formed integrally with a web-like support 16 attached as indicated at 17 to lugs 18 integral with the base of section 2.

The blade 19, of the plane, is longitudinally slotted in a manner common to the art and is held in place against bed plate 15 and against an enlargement 20 of the plane base through the medium of an attaching plate 21, said plate having associated therewith a cam lever 22 pivoted as at 23 to the plate 21, the head 24 of the cam lever being adapted for frictional engagement with the top or forward face of the blade 19 to serve as a means whereby the said blade is held immovable relatively to the bed plate 15 and the fastening plate 21 in firm frictional engagement with a retaining screw 25 operating within a slot 26 of the plate 21 and extending through blade 19, said plate 15, and into an enlargement 26′ of the web-like support 16 above mentioned. The cutting edge of the blade 19 extends beneath the operating surface of the plane through an opening or transverse slot 27 formed at the forward end of plane section 2 and at the base of partition 3 thereof.

When it is desired that the depth of cut be varied to a small degree, operating screw 12 is partially rotated through manipulation of handle 28 forming a part thereof, causing plane section 1 to move vertically relatively to plane section 2, thus exposing a greater portion of the blade 19 to view. Should such adjustment prove insuflicient, and greater adjustment be desired, cam lever 22 is raised to remove attaching plate 21 out of frictional engagement with retaining screw 25 and blade 19 out of frictional engagement with bed plate 15, in which event, blade 19 is adjusted vertically as desired. When adjusted, cam lever 22 is again forced into the position shown in Fig. 3, retaining screw 25 having been previously adjusted, such forced movement of the said lever causing the attaching plate 21 to again frictionally engage the retaining screw and the blade 19 to remain immovable relatively to the said plate 15 of the plane.

A knob 29 and a handle 30 are made fast to the respective sections 1 and 2 of the plane in a manner common to the art.

From the foregoing, taken in connection with the accompanying drawings it is apparent that minute or finger adjustment is made possible by the provision of the operating screw 12; that unlimited adjustment is made possible by the cam lever 22; and that by the provision of the extensions 5 and 7, arranged as shown to advantage in Fig. 2, the sections of the plane are held against longitudinal and lateral movement independently of each other, yet, when it is desired that one of the sections be adjusted relatively to the other, such vertical adjustment is permitted.

In reduction to practice, I have found that the form of my invention, illustrated in the dravvings and referred to in the above description, as the preferred embodiment, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, Without sacrificing any of the advantages of my invention, as defined in the appended claims.

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

In a bench plane; a stock section having a front wall extending at a substantially right angle to the planing surface thereof, and a frog mounted in spaced relation to said wall supporting the planing knife; in combination with a second stock section having a wall extending upwardly at right angles to the planing face thereof, and in spaced relation to the rear edge, means carried by said walls whereby said sections may be held in interlocking engagement, said second section providing a throat above the planing edge of said knife, and means to adjust said sections relatively, whereby the throat will be enlarged or constricted consistent with the variations of the depths of cut of the planing knife.

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

To all whom it may concern:

Be it known that I, JOHN F. THUNELL, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Rabbet-Planes, of which the following is a specification.

This invention relates to hand planes, and pertains especially to planes for cutting curved or circular rabbets of various forms and curvature, and having adjustable runners.

The object of the invention is to provide novel and peculiar means for adjusting a pair of plane runners equally and without variation between the runners in perfecting their uniform adjustment.

A further object of the invention is to provide mechanism connecting the free end of the runners of a rabbet plane and fulcrumed within the plane body whereby the runners may be given uniform adjustment, and to furnish novel and peculiar means for operating said mechanism to give the runners such uniform curvature as desired or as occasion may demand, without separate adjustment of the runners.

Various other objects, advantages and improved results are attainable in the practical application of the invention as hereinafter fully described.

In the accompanying drawings forming part of this application :– Figure 1 is a top view of a rabbet plane embodying my invention. Fig. 2 is a sectional view taken on the plane indicated by the dotted line A–A Fig. 1, with the bit adjusting device removed. Fig. 3 is a detail plan view of the runner operating levers and follower block. Fig. 4 is a detail perspective view of the screw-locking device. Fig. 5 is an enlarged sectional view taken on the dotted line B–B Fig. 2. Fig. 6 is a similar view taken on the dotted line C–C Fig. 2.

The same reference characters denote the same parts throughout the several views of the drawings.

The means operated by the screw 1, for adjusting the bit 2, is covered by my application Ser. No. 872,608, allowed July 12, 1915, and therefore the same is not claimed in this application, and while the runners of this application are the same as those shown in said allowed application, the mechanism for operating the flexible runners 3, and the device for locking said mechanism to fix the runners in various positions constitute the subject of this application.

The runner operating mechanism comprises a pair of duplicate levers 4, pivotally connected at 5 with the movable end of the runners 3, by a forked hanger 6, pivoted at 7, to the outer end of the levers 4 where they are united in pairs. The levers 4 are branched laterally in pairs from their outer end and extend through the inclined throat wall 3 and adjacent to the side walls 9 of the throat. The pair of levers for one runner are pivoted to the pair of levers for the other runner by pivot pins 10, and the levers of one pair are pivoted at 11, to the throat walls 9, while the levers of the other pair are fulcrumed to and between the walls 9 and a vertical wall 12. One pair of the levers are operated through slots 13, in the wall 8, and the other pair of levers are operated through slots 14, in the wall 12. The device for operating the levers comprises a follower block 15 having a screw threaded aperture 16, for a screw 17, and a pair of arms 13 fulcrumed to the lever 4 by means of the lever pins 10. The screw 17 is anchored by means of a bracket 19 secured to and projecting inwardly from the wall 12, and said screw projects through a top wall 20 of the plane and is provided with a milled head for turning the screw in the anchor bracket, whereby the follower block 15 is moved vertically, and by such movement operates the levers 4 which carry the runners 3 to various curved positions as desired or as occasion may demand. The device for locking the screw and thereby fixing the levers and the runners in desired position for operating the plane, comprises a plate 21 slidably contained within the wall 20, and having an aperture 22 for the screw 17, and a screw stem 23 provided with a thumb nut 24 working against the outer face of the wall 20 for sliding the plate into and out of engagement with the screw. Obviously when the screw is locked the levers 4 and the runners are fixed in position for operating the plane.

It will be seen that the movement of the levers and runners is not only accomplished by operating the screw 17, but the screw and its locking device controls the levers and the runners so that the set position of the runners may be maintained during a planing operation. It will be further observed that the runner adjusting mechanism affords means for giving the runners minute curvatures, and that such curvature must be the same in both runners, under one and the same movement of the screw.

I do not wish to limit myself to any particular number of levers for operating the runners, to the size, material or shape of any of the parts of my invention, nor to the particular location of the pivot and fulcrum points of the runner operating levers, but reserve the right to make such changes and variations in the practical application of the invention as may come within the scope of the appended claims.

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

1. In a plane, a pair of flexible runners having one end secured opposite the bit slot of the plane, a pair of fulcrumed levers pivotally connected with each runner, the levers of one runner being pivoted to the levers of the other runner, a vertically movable screw block having arms pivoted on the pivot of said levers, a vertical screw extending through the block for operating the levers, an anchor bracket attached to the outer side of the stock and holding the lower end of the screw, and a plate slidable at right angles to the screw for locking the screw.

2. The combination with flexible plane runners, runner levers pivoted together and to the walls of the plane stock, a follower screw block movable vertically between the levers of one pair and having arms pivoted to the connecting pivot of said levers, a vertically anchored screw working through the block for operating the levers, and a plate contained within the top of the stock and slidable in the path of movement of the screw for locking the screw.

3. In a device for operating flexible plane runners, two pairs of pivoted runner levers, pivots connecting the inner end of the levers, a follow screw block between the levers of one pair and having a pairof arms pivoted on said pivots, a vertically anchored screw working through the block for operating the levers, and a locking plate having a screw stem for sliding the plate into the path of movement of the screw.

In witness whereof I hereunto set my hand in the presence of two witnesses.

To all whom it may concern:

Be it known that I, GEORGE W. HARVEY, citizen of the United States, resident of Jasper, in the county of Jasper and State of Missouri, have made a certain new and useful Invention in Bench-Planes; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view of the invention. Fig. 2 is a section on the line 2–2, Fig. 3. Fig. 3 is a section on the line 3–3, Fig. 1. Fig. 4 is a section on the line 4–4, Fig. 1. Fig. 5 is a detail perspective view of the bit iron holder. Fig. 6 is a detail top plan view of the adjusting lever.

The invention has relation to bench or carpenters’ planes, and it consists in the novel construction and combination of parts, as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the numeral 2 designates the stock, having side flanges 3, 3, and 4 is the bit iron holder, having an incline 5 and lower side flanges 6, 6, pivoted to the flanges of the stock by a strong cross-pin 7. The bit holder has in its incline a slot 8, open at its upper end, and is provided with a stud 9, projecting upwardly at right-angles to the incline and having a head 10 at its upper end.

Resting upon the bit iron holder incline is the bit iron 11, a cap iron 11′ having therein a slot 12, of keyhole form, adapted to engage the head of the stud, when the bit and cap irons will slide downwardly to position, the contracted portion of the slot engaging the shank of the stud. Projecting from the lower wall of the bit iron, intermediately of its length, is a stud 13, fitting within the slot of the incline. An upwardly projecting, inclined spring arm 14 is secured at its lower end to the lower wall of the incline, and carries intermediately of its length an upwardly projecting squared stud 15, engaging a squared slot or seat 16 of the bit iron.

A wedge 22 has, intermediately of its length, a keyhole slot 23 therein, engaging over the headed end of the stud 9, said wedge having at its upper end a screw 24, having contact with the upper portion of the cap iron, to press said iron, with the bit iron, downwardly against the incline of the bit iron holder and bind it securely in place thereupon.

Located below the spring arm, about midway between the same and the floor of the stock, is a rearwardly projecting inclined lever 18, having at its lower end a pivot upon a vertical pin 19 of the stock, said lever having at its lower end an upper cam surface 20, against which the lower wall of the incline bears, so that when the lever is moved to one side or the other, the cam will engage the bit iron holder and move the same upwardly or allow the same to move downwardly, upon the cross~pin as a pivot, the bit iron holder and bit iron carried thereby rocking upon said cross-pin, to adjust the cutting edge upwardly or downwardly and thereby vary the thickness of the shaving, said lever being easily worked by one finger, without changing the grip upon the handle, so that delicate adjustments, to vary the thickness of the shaving, may be conveniently made. As the bit iron holder and bit iron are adjusted as stated, to vary the thickness of the shaving, a transverse spring 21, located beneath the rear portions of the flanges 6 of the bit iron holder, is put under tension, this transverse spring acting to press the bit iron holder in contact with the cam, and accomplishing the downward recking movement of the bit.

What I claim is:

1. In a plane, a stock, a bit iron holder pivoted to said stock, a bit iron upon said holder, a pressure spring for said holder and said bit iron in rear of said pivot, and a transversely movable adjusting lever having a vertical fulcrum pin connection with said stock and a cam end in contact with said holder forward of said pivot.

2. In a plane, a stock having side flanges, a bit iron holder having side flanges, a bit iron upon said holder, a pivotal cross-pin connecting the flanges of said stock and said holder, a pressure spring for said holder and said bit iron in rear of said cross-pin, and transversely movable adjusting lever having a vertical fulcrum pin connection with said stock and a cam end in contact with said holder forwardly of said cross-pin.

3. In a plane, a stock, a bit iron holder pivoted to said stock, a bit iron upon said holder, a pressure spring for said bit iron and said holder in rear of the pivot thereof, In testimony whereof I affix my signature, and a transversely movable rearwardly projecting lever having at its lower end a vertical fulcrum pin connection with the stock and an upper cam surface bearing against the said holder forwardly of the pivot thereof.

To all whom it may concern:

Be it known that I, JAMES F. BITTLE, a citizen of the United States, residing at Brunswick, in the county of Frederick and State of Maryland, have invented new and useful Improvements in Planes, of which the following is a specification.

This invention relates to wood-workers’ planes, the primary object being to provide a tool of this character which includes a stock, an adjustable main plate with which a cutting bit is adapted to be connected for temporary use, the plate being mounted at the usual inclination within the stock of the plane. and means by which the main plate may be adjusted longitudinally with ease and absolute accuracy to a definite degree, when setting the bit.

A further object of the invention is to provide a main plate having means thereon for securing a plurality of cutting bits thereto, one of the bits being in operative position for active use and the other bit or bits being positioned above the first bit in inoperative position. These bits are interchangeable and the bit, which is in operative position, is reversible and is double-edged so that either cutting edge may be used when the other has become dull.

The invention consists in the features of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a side elevation of a plane constructed in accordance with the invention; Fig. 9. is a longitudinal sectional view taken vertically therethrough: Fig. 3 is a transverse sectional view on line 3–3 of Fig. 2; Fig. 4 is a transverse sectional view on line 4–4 of Fig. 1; Fig. 5 is a detail, rear elevation of the main plate, showing two bits connected therewith; Finn 6 is a front elevation of the same; and, Fig. 7 is a side elevation of the same.

In the drawings, the numeral 1 designates the base plate of the plane which is provided with the usual handles 2 and 3. A frog 4 is secured detachably to the base plate 1 between its side flanges 5 by means of the attaching screws 6. This seat block is constructed so that its front face 7 is arranged in proper angular relation to the throat 8 in the base plate. A transverse fulcrum bar 9 extends between the side flanges 5 in front of the seat block in slightly spaced relation thereto. These parts of the device constitute the stock.

A main plate 10 for the bits of the plane, which is elongated and is constructed preferably of tempered steel, is adapted to be mounted upon the front face of the seat block inwardly of the fulcrum bar 9. This plate is shown in detail in Figs. 5 to 7. This plate is provided medially with a pair of transversely spaced pins 11 upon its rear face, which are adapted to engage within the transversely spaced openings 12 in a cutting bit 13, when the latter is positioned upon the said face of the plate in inoperative position. This bit is adapted to be constructed much shorter in length than the main plate, and a second bit of like construction is adapted to be mounted below the first bit upon the plate 10. The lowermost bit, which is in active position, is adapted to project below the lower end of the main plate, and is sharpened at both ends so as to provide interchangeable cutting edges 15. The said lower end of the main plate is bowed longitudinally, as at 16, so as to provide a yieldable jaw whose lower edge 17 is adapted to engage the bit in active position. Each bit to be used in connection with the plane is double-edged, so that, with two bits upon the plate, four cutting edges are provided, which may be placed in position for active use hv properly interchanging or reversing the bits in a manner which should be readily understood. Each bit is provided medially with a slot 18 which extends longitudinally and the under face of the bit is serrated adjacent to this slot as at 19 so that, when the bit is mounted in its lowermost, operative position, the serrations may be engaged by those of a securing plate 20, which plate is adapted to be secured to the main plate by means of an adjustable clamping screw 21 whose threaded portion extends through the bit slot and is engaged within a threaded opening 22 in the main plate and whose head is engageable with the rear face of the clamping plate 20.

A pivotal retainer 23 is adapted to be mounted between the fulcrum bar 9 and the front face of the main plate with its shoulder 24 engaging the said bar. and an adjustable thumb screw 25 is mounted within the upper end of the retainer for engagement with the upper end portion of the said main plate. The lower end of the retainer is adapted to engage the bowed jaw portion of the main plate, whereby, when the thumb screw 25 is adjusted properly, the retainer may be moved upon the bar 9 as a fulcrum so as to exert rearward pressure upon the jaw 16 and thus secure the bit effectively in its set position within the frame.

The seat block 4 is provided upon its upper edge with an extension 26 which is provided in its upper edge with a longitudinal slot 27. An adjusting lever 23 is pivotally mounted upon the under face of the upper end portion of the main plate 10 for transverse swinging movement upon a pivot pin 29. The lower end portion of the adjusting lever is oiset rearwardly as at 30 and is provided terminally with an inbent lug 31 for engagement within the slot 27 of the seat block extension. The upper end of the adjusting lever projects past the upper edge of the main plate and is bent to form a handle 32 by which it may be grasped when it is desired to adjust the main plate and consequently the bits attached thereto in a lateral direction, it being understood that the said main plate fits loosely within the frame so that its side edges are spaced slightly from the side flanges 5 of the base plate. The main plate turns in such adjustment upon the head of the clamping screw 21 for the operative bit, owing to the fact that the latter is adapted to rest within a longitudinal slot 33 which is provided in the front face of the frog 4 at its lower edge.

The frog extension 26 is provided in alinement with the slot 13 of the inoperative bit with a longitudinally arranged slot 34 in which the active end 35 of a rocking lever 36 is movably mounted. this lever being pivotally connected with the said seat block extension by means of a transverse pivot pin 37 for movement in a vertical plane. The active end of this lever is adapted to project through the bit slot into an opening 38 provided in the main plate. The lower end of this rocking lever is provided with rack teeth 39 for engagement with the worm gear 40 of a rotatable adjusting member 41, which latter is pivotally mounted upon a screw 42 which extends rearwardly from the seat block and has its forward end threaded into a recess 43 provided in the same. A knurled manipulating handle 44 is provided upon the adjusting member. By adjusting this member 41, when the thumb screw 25 has been loosened, the main plate with its bits may be shifted longitudinally so that the cutting edge of the operative bit may be set to cut shavings of a predetermined thickness.

It is to be understood that the bits are adapted to be used in wooden stocks of the ordinary well known type, as well as in iron stocks, such as that shown in the drawings.

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent to those skilled in the art to which this invention relates that I have provided a plane which is provided with a plurality of bits which may be interchanged and reversed whenever necessary to afford a sharp cutting edge, thereby rendering the tool capable of being used for a considerable length of time without the necessity of sharpening any of its bits. The advantages of this construction should be obvious in view of the fact that it is often necessary to employ a plane upon buildings and in other places where a grindstone or other sharpening device is not accessible. A further feature of the invention, which adds to its usefulness and decreases the time and labor ordinarily expended in setting the bit of such a plane, is the provision of the specific means for adjusting the main plate bearing the bits longitudinally upon the seat block. The plane is also composed of few parts and is extremely simple in construction so as to be durable, capable of having its component parts readily detached and assembled, and inexpensive in the cost of manufacture.

What is claimed is:

A wood-worker’s plane comprising a stock, a frog, an extension formed integral with said frog having a slot opening out through the upper end thereof and another slot formed at the point of intersection of the extension with said frog, a bit carried by the frog, a cap carried by the bit, means extending through said cap and bit for securing the latter to the former, a lever pivoted to said plate and having a lug for engagement with the slot formed within the upper end of the extension for effecting lateral adjustments of said plate and bit. and means for effecting a longitudinal adjustment of said plate and bit.

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

To all whom it may concern:

Be it known that I, JOHN F. THUNELL, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful improvements in Hand-Planes, of which the following is a specification.

This invention relates to bit adjustments for hand planes, and the object of the invention is to provide novel and peculiar means for adjusting hand plane bits which shall be of simple construction, conveniently assembled, and accurately manipulated.

The object of the invention is to provide novel and peculiar means for adjusting and fixing the plane bit, and special means for hanging and adjusting the base or surface bearing plates of the plane.

A further object of the invention is to provide in the bit adjustment, convenient, simple, durable and effective means for giving the bit minute, accurate and positive adjustment independent of the base plate adjustment.

A still further object of the invention is to provide a pair of surface or runner plates, and a screw rod hinged to each plate, and a pair of adjusting and locking nuts for each rod, the adjusting nuts being held within the plane stock.

Other objects, advantages and improved results will be found in the practical application of the plane.

In the accompanying drawings forming part of this application: Figure 1 is a side elevation showing in dotted lines the various positions of the base plates. Fig. 2 is a sectional view of the bit device. Fig. 3 is a detail cross section on the dotted lines x–x, Fig. 2. Fig. 4 is a detail perspective view of the bit bracket.

The same reference characters denote the same parts throughout the several views of the drawings.

The plane stock or body 1, has a concavity 2 in its top in which set-screws 3 and 4 are operated in connection with a bit 5 and its keeper 6. The screw 3 works through a hinged carrier 1a, to connect the keeper therewith, and the thumb screw 4 works through the upper end of the keeper as usual. A transverse opening 7 is made through the stock under the ccncavity 2, and a bit slot 2a is made through the bottom wall of the opening 7. The under side of the stock is cut out at 8, for the purpose of reducing the weight of the plane, and for the purpose of housing the bit adjusting device. The bit adjusting device comprises a bracket the long plate 9 of which has a lug 8a working in the bit slots 9a covered by the plate 9, and the short plate 10 of the bracket is secured to the inclined wall 11 of the cut out portion 8 of the stock. The plate 10 forms a collar 10a in which a worm screw 12 is operated. Said screw having a stem extending through the top of the stock on an incline and parallel with the bit, and the stem is provided with a thumb head 13 for operating the screw. The plate 9 is provided with a follower projection 14 meshing with the screw 12, and the plate 9 has a forked end for the plate 10.

The pair of flexible runners 15, have their inner ends secured flush with the bit slot 2a, and the outer end of each plate is curved upwardly. A screw rod 16 is hinged or pivoted at 17 adjacent to the said curved end of each plate, and said rods extend through the ends of the stock 1. The ends of the stock are provided with transverse slots 18 and hold thumb nuts 19 for operating the rods 16, and set nuts 20 are provided for holding the rods in set position. One end of the stock is provided with a hand abutment 21 projecting above the nut 20 at this end of the stock, and thereby prevents the hand from interfering with the nut and rod.

It will be observed that the follower answers two purposes, it forms the connection between the bit and the bracket, and it also affords means for imparting to the bit the movement of the worm screw.

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

In a bit plane, a plane throat the under wall of which has a slot lengthwise thereof, a plate of larger area than the slot and slidable on the under face of said wall opposite the slot, a lug on the upper face of the plate and projecting through the slot into engagement with the bit, a lug on the lower face of the plate, and a screw spaced apart from said wall equal to the thickness of the plate and engaging the plate and the lower lug to keep the upper lug in engagement with the bit for longitudinal adjustment by the screw.

In witness whereof I hereunto set my hand in the presence of two witnesses.

To all whom it may concern:

Be it known that I, HERBERT G. COLLINS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more particularly to the means for adjusting the cutter and clamping it in position.

The improvements are particularly applicable to molding planes, but may also be used in connection with planes of other types.

The primary objects of the invention are to provide improved and simplified means for clamping the bit or cutter in the desired adjustment; to furnish simple and effective means for adjusting the cutter longitudinally; and to improve the general construction and operation of devices of the class to which my invention relates.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the main stock of a molding plane embodying my improvements; Fig. 2 is a side elevation of the cutter clamping and adjusting means, looking from the opposite side of the plane; Fig. 3 is a top plan view of the parts shown in Fig. 2; Fig. 4 is a section on line 4–4 of Fig. 2; Fig. 5 is an enlarged section on line 5–5 of Fig. 1; Fig. 6 is a detail showing the clamp in position to release the bit or cutter; Fig. 7 is a detail showing the seat for the cutter and clamp; Figs. 8, 9 and 10 are details of the clamp; Fig. 11 is a detail of the clamping nut; Fig. 12 is a detail of the clamping nut socket; Fig. 13 is a section on line 13–13 of Fig. 1; and Fig. 14 is a detail of the bit or cutter.

Referring to the drawings, I have shown my improvements applied to the main stock 20 of a molding plane, which stock is provided with a handle 21 and throat 22 of usual form. A bit or cutter 23 is clamped against the side of the stock by means of a clamp 24 in such a manner as to project into the throat 22. The clamp 24 is operated by a clamp nut 25 located at that side of the stock opposite the cutter, and the cutter is adjusted lengthwise, i. e., into and out of the throat 22 by means of an adjusting screw 26, engaging a threaded socket 27 at the top of the stock and cooperating with the cutter in the manner to be presently described.

Referring particularly to Fig. 7, it will be noted that the cutter 23 and clamp 24 are partially accommodated in a recess or seat 28 formed in one side of the stock. At the lower portion of the recess is a laterally extending ledge or flange 29, which assists in supporting the cutter from beneath. Opposite the ledge or flange 29, i. e., at the top of the recess 28, is a somewhat similar projecting ledge or flange 30, against which fits the upper edge or surface of the clamp 24. The lower or under surface 31 of the ledge 30 is located in a plane somewhat out of perpendicular with respect to the vertical longitudinal plane of the stock, and said surface 31 cooperates with a correspondingly inclined surface 32 at the upper part of the clamp.

The lower surface 33 of the clamp is parallel with the cutter seating surface of the ledge 29. The cutter is clamped tightly in its seat by drawing the clamp 24 laterally into the recess 28. In doing this, the inclined surfaces 31, 32 of the ledge 30 and clamp 24 respectively cooperate in such a manner as to force the lower surface 33 of the clamp tightly against the cutter.

In the embodiment shown, the clamp 24 is adjusted by means of a threaded shank 35 extending laterally therefrom through an opening 36 in the stock, and engaging interior threads of the clamping nut 25 previously mentioned. The opening or bore 36 in the stock is of somewhat greater diameter than the shank 35, so that the latter will have a certain amount of clearance. The nut 25 is suitably fixed against lengthwise movement, as by means of a collar 37, engaging a grooved socket 38 at the side of the stock, as shown in Fig. 4. Assuming that the shank 35 and nut 25 are provided with the usual right-hand threads, rotation of the nut 25 in a clockwise direction will draw the clamp 24 laterally into its seat to clamp the cutter tightly in position, as shown in Fig. 3. When the nut 25 is turned in a counter-clockwise direction, the clamp 24 will be forced laterally out of its seat, and the clearance in the bore 35 will allow the clamp to swing away from and release the cutter as the inclined surface 32 of the clamp slides outward along the cooperating surface 31 of the stock.

In assembling the device, the nut 25, which preferably has a circular milled head, is entered laterally into its socket 38, which is permitted by having said socket open throughout a portion of its periphery, as shown at 38a in Fig. 12. As the nut is slipped into its socket, it will be held against lengthwise movement by the engagement of its collar 37 with the corresponding groove in the socket, and the shank 35 of the clamp will be passed through the hole 36 to engage the threads of the nut in an obvious manner. As the nut is held against displacement in an axial direction, the clamp 24 must move laterally into and out of its seat, as the nut is turned in opposite directions respectively. During the inward movement, the portion 30 of the stock acts as a cam to force the clamp toward the cutter-supporting portion or ledge. In the outward movement of the clamp, the clearance around the shank of the latter permits the clamp to move away from the cutter.

The lengthwise adjusting screw 26 for the cutter is provided with a filled head 26a having at its lower portion an annular shoulder 26b The shoulder 26b projects axially relative to the adjusting screw. Below the shoulder 26b is a shoulder 26c projecting perpendicularly relative to the adjusting screw. The shoulder 26c engages a notch 23b formed in the side of the cutter, so that as the adjusting screw is turned in one or the other direction the cutter will be moved into or out of the throat. The shoulder 26b of the adjusting screw engages a notch 23a at the top of the cutter and effectively holds the cutter in engagement with the shoulder 26c. Movement of the cutter in an outward direction relatively to its seat, i. e., away from the side of the stock, is prevented by the engagement of the shoulder 26b with the notch 23a and by the engagement of the clamp with the body portion of the cutter.

The foregoing description is necessarily a detailed one in so far as it concerns the particular embodiment of my invention selected for illustration.

Various modifications of the construction may be adopted within the scope of the invention as defined in the claims.

What I claim is:

1. In a plane, the combination of a stock having a cutter seat opening outwardly at one side of the plane, a cutter in said seat, a clamp for the cutter, a lengthwise adjusting screw for said cutter at the opposite side of the plane socketed in the stock, at one side of, and approximately parallel to said cutter, and a shoulder on said screw directed axially of the latter and engaging a shoulder at the upper portion of the cutter, whereby said screw prevents lateral displacement of the cutter relative to said cutter seat, as the cutter is adjusted by the screw; substantially as described.

2. In a plane, a cutter seat, a cutter having a notch at one side edge, and a notch at the top edge, in combination with a lengthwise adjusting screw, having a perpendicular shoulder to engage with the first named notch, and an axial shoulder to engage with the second named notch, the cutter seat opening out at the side of the plane opposite the adjusting screw, substantially as described.

3. In a plane, the combination of a stock having a cutter seat at one side, a cutter in said seat, having a notch at the top edge and a notch in the side edge toward the stock, a clamp for the cutter, a lengthwise adjusting screw for said cutter, socketed in the stock at one side of, and approximately parallel to said cutter, a shoulder on said screw, engaging the notch in the side edge of the cutter to provide for the upward and downward adjustment of the latter, and a second shoulder on said screw directed axially of the screw and engaging the notch at the upper edge of the cutter, whereby said screw prevents lateral displacement of the cutter relative to its seat., as the cutter is moved up and down by said screw, the cutter seat opening out at the side of the plane opposite the adjusting screw; substantially as described.

4. In a plane, the combination with a stock, of a cutter mounted therein, and means for adjusting the cutter longitudinally including an adjusting screw operatively mounted on the stock, said screw having a projecting portion extending axially thereof and the cutter having a slot extending longitudinally thereof in which said projecting portion may fit for rotation and interlock to prevent lateral displacement of the cutter in either direction edgewise thereof.

5. In a plane, the combination with the stock having a cutter receiving portion opening outwardly at one side of the plane, of a cutter mounted therein, and means located at the opposite side of the plane for adjusting the cutter having a part adapted to engage a complementary part of the cutter to project the cutter with reference to the stock, and having another part adapted to engage another complementary part of the cutter to prevent lateral displacement of the cutter.

6. In a plane, the combination with a cutter seat opening toward one side thereof, an adjusting device located inwardly of said seat, said adjusting device having an undercut bit receiving portion and a shoulder therebelow, and a bit having a longitudinally extending projection adapted to be introduced into the undercut portion of the adjusting device when the bit occupies an inclined position and the bit having a portion adapted to engage the shoulder of the adjusting device when the bit is shifted from said inclined position to a position parallel to its seat, whereby the adjusting device will interlock with the bit to eifect raising and lowering of the bit substantially as described.

7. A bit for planes of the character described, having a cutting edge at one end thereof, a notch in the opposite end of the same, and a notch in one of its side edges located near said notched end substantially as and for the purpose described.

In witness whereof, I have hereunto set my hand on the 10th day of November, 1913.

To all whom it may concern:

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

This invention relates to metal tool bodies and the process of forming the same. The tool body so formed is designed to provide lightness as far as weight is concerned, with effectiveness of structure and strength to resist load strains under practical working conditions. The parts are so combined and connected that there will be practically no distortion due to load strain, or at least so that distortion is minimized. The tool body so formed is light yet substantial and combines with this desirable quality the further desideratum of rigidity.

For the purpose of illustrating and describing a specific embodiment thereof, I have selected a metal plane, the specific construction of which is described in the following detailed specification, taken in connection with the accompanying drawings which illustrate a preferable embodiment of such a plane body.

In these drawings, — Figure 1 is a plan view of the plane body, parts of the plane being omitted. Fig. 2 is a longitudinal vertical section on the line 2–2 of Fig. 1, portions of the operative parts of the plane being shown to illustrate the purpose of the body structure. Fig. 3 is a plan view of a metal blank from which the outer shell or case of the body is formed. Fig. 4 illustrates the metal blanks from which the inner face of the body is formed, these blanks being subsequently treated to provide the strengthening corrugations and tool seats. Fig. 5 is a detail of construction.

Referring to the drawings by numerals, 1 designates the base or shoe portion of the outer shell slotted at 2 to provide the usual cutter throat. This base is provided with side walls or flanges giving the shell or shoe a channel formation. Preferably this outer shell of the plane body is formed of sheet metal stock which may be bent up from a single blank, such as shown in Fig. 3, to form the side walls or flanges 3 and the base 1. This outer shell by itself will hardly be substantial enough to stand the load strain of actual working conditions. I have provided an inner bracing means for this outer shell which bracing means is designed to carry the operating parts of the tool and take a large portion of the load strain from the outer shell. I preferably form this bracing means also from sheet metal stock.

In Fig. 4, 4 designates a metal blank having laterally extending ears 5, and 6 designates a metal blank of the same width but greater length having similar laterally extending ears 7. The two blanks, before the bending operation about to be described, are each provided with threaded bores 3 therein to receive screws from the handle and other parts of the tool. The first blank 4 is of a width to fit between the side walls 3 of the outer shoe. It is treated in a press or other machine to form longitudinal strengthening corrugations 9 therein and preferably also laterally extending corrugations 10, the blank at the intersection of these corrugations being formed with a raised seat 11 for the hand-knob of the plane to rest upon. At the rear end of the longitudinal corrugation 9 the blank is bent laterally to form an upwardly extending bridge 12, the ears 5 being turned inwardly to rest against the side walls or flanges 3 of the outer shell. It will be understood that the side edges of the formed blank will have a snug fit within the side flanges 3 of the outer shell, and that the ears 5 and the edges of the bridge 12 will likewise abut thereagainst at a point substantially above the base 1. The formed blank 4 will be positioned forwardly of the throat 2 in the outer shell. The blank 6, which is designed to carry the cutter, handle, etc, is positioned to the rear of this cutter throat slot. Its forward edge is struck up to form a raised seat or bridge 13, which may constitute a seat for the plane-frog 14; (Fig. 2), this frog having attaching screws 15 which extend through the apertures 8 and into the threaded bores 16 in a strengthening metal piece or blanking 17, which will be positioned under the seat or bridge 13 and above the upper face of the base 1 of the outer shell. This blanking 17 is preferably previously secured to the seat in a suitable manner, as by riveting, although the welding process hereinafter described may also be employed.The ears 7 of the blank 6 are bent upwardly to abut against the sides 3 of the outer shell at points substantially at the base of said shell. The blank is also treated in a press or other instrumentality to provide it with longitudinally extending corrugations 18 and also preferably with a plurality of transversely extending corrugations 19. Intermediate its ends the corrugation 18 is enlarged and elevated to form the raised seat 20 to which the tool handle 21 may be attached by screws 22 taking into the threaded bores 8 previously formed in the blank. When these formed blanks have been assembled in their proper positions upon the upper face of the base of the outer shell, they are preferably secured thereto and rigidly united therewith by fusing the parts together. The method I preferably employ is known as “spot welding.” This spot welding operation preferably takes place about the outer edges of the formed plates so that these formed plates will be fused to the outer shell at points along the lines of the edges of the plates so as to make the outer shell stiii at the point where the side flanges are bent upwardly therefrom, which would otherwise make the body weak at that point. The ears 5 and 7 are also welded to the side walls and with the raised bridge edges, seats, etc., strengthen the outer shell at points above the bend of the side walls, the fusion of the metal taking place therefore, at both sides of the bend and the inner plates. The spot welding may take place both at the outer edges of the plates 4 and 6 and inwardly of said edges and between the edges and the corrugations. These corrugations materially strengthen the base against distortion through working strain, and as the seats for the tool operating parts are raised, these parts do not contact with the base. Consequently the operating load strain is largely taken by the corrugations which, together vvith the bridges, prevent distortion of the base.

What I claim therefore and desire to secure by Letters Patent is:

1. A plane having a tool body of deformable metal, comprising an outer shell having a base and integral upwardly extending side walls, and an inner plate permanently secured to said ba.se and to said upwardly extending side walls, said inner plate having intersecting longitudinally and laterally extending raised strengthening corrugations formed therein bracing the outer shell against longitudinal and lateral strains, and forming a handle support and securing means.

2. A tool body of deformable metal comprising an outer shell having a base and integral upwardly extending side walls and an inner plate permanently secured to said base and to said upwardly extending side walls, said inner plate having intersecting longitudinally and laterally extending raised strengthening corrugations formed therein and said corrugations being broadened at their intersection to provide a longitudinally and laterally braced seat for a tool operating part, raised above the plane of the base whereby communication of deforming strains from such tool operating part to said base is prevented.

To all whom it may concern:

Be it known that I, WILLIAM E. SPARKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and more especially to planes constructed wholly of metal.

One of the primary objects of the invention is to provide a light, strong, durable and inexpensive plane, wherein the stock or frame, the frog, and the clamp for the cutter are constructed of sheet metal. To this end the parts mentioned are of novel form and are combined and assembled in a novel way.

Another object of the invention is the provision of certain improved features of construction in what is known as a low angle block plane, more particularly the mechanism for giving the bit or cutter its lengthwise adjustment, and the location of such adjusting means in such a position that the head of the adjusting screw for the cutter serves as a palm rest when the plane is in use.

However, although my improvements are of particular advantage in low angle block planes and in planes constructed for the most part of sheet metal, certain features will be found advantageous in planes of other types.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

ln the accompanying drawings, Figure 1 is a side elevation of a low angle block plane embodying my improvements, Fig. 2 is a top plan view of the same, Fig. 3 is a section on line 3–3 of Fig. 2, Fig. 4 is a front end elevation of the plane, Fig. 5 is a rear end elevation, Fig. 6 is a fragmentary plan view of the stock with the cutter and clamp removed, Fig. 7 is a section on line 7–7 of Fig. 1, Fig. 8 is a detail bottom view of the frog prior to assembling, Fig. 9 is a detail bottom view of the clamp, and Fig. 10 is a detail section on line 10–10 of Fig. 2.

Referring to the drawings, the stock or body 10 is of the usual channeled section but instead of being constructed of cast metal as customary, it is bent up from sheet metal such as sheet steel. The frog 11 is also constructed of sheet metal and it is given the special form shown in Figs. 3, 6, 7 and 8. The frog comprises a plate 11a provided with integral extensions at opposite sides which are bent downward to form legs 12. Rivets 13 connect these integral sheet metal legs with the side walls of the stock between which the frog is set. The legs 12 are so located relatively to the frog and stock as to give the main part of the frog the required inclination to the horizontal. The legs 12 secure the frog to the stock at the rear end of the frog and the forward end of the frog is secured to the stock by means of a lug 14 struck out from the plate 11a and lying in contact with the upper surface of the bed or sole 15 of the plane. In the form shown the downwardly bent lug 14 of the stock is secured to the bed 15 by spot welding, but of course, a rivet or other fastening member could be used if desired.

At the rear of the frog are two downturned lugs 16, 17 for the adjusting screw 18. The lug 17 is struck out of the plate 11a leaving an opening 17a therein, and the lug 16 extends downwardly from the rear edge of the frog substantially parallel to the lug 17. These lugs are provided with threaded perforations engaged by the shank 19 of the adjusting screw 18. The shank 19 is manipulated by a large head or wheel 20 having a neck 21 and a shoulder or collar 22.

The cutter 23 is positioned on top of the frog 11 in the usual manner with its forward extremity in the throat 24 of the bed or sole. The cutter 23 is provided at its rear under portion with a series of transverse arcuate grooves 25 any one of which is adapted to fit snugly over a portion of the periphery of the shoulder or collar 22 on the adjusting screw 18. This provides for the lengthwise adjustment of the bit or cutter as the adjusting screw is moved forwardly or rearwardly in the lugs 16, 17, as will be understood. The shoulder 22 is free to rotate in the groove 25 in which it engages, but the provision of the grooves form shoulders cooperating with the shoulder 22 in such a manner that the cutter or bit partakes of the lengthwise movement of the adjusting screw.

The clamp 26 like the stock and frog is also constructed of sheet metal. Its strength is considerably increased by forming the same of a sheet metal plate having its edges flanged or downturned, substantially throughout the contour thereof, as indicated at 27. This stiffens and strengthens the clamp considerably and it is also reinforced by an integral rib 28 stamped in the same. The clamp is provided with the usual key-hole slot 29 adapted to fit over the usual headed stud 30 which projects up from the frog between the lug 14 and the opening 17a. At the front of the clamp 26 the downturned edge 27 rests on the upper face of the cutter, and is clamped against the cutter at that point by a screw 31 extending through a threaded opening 32 at the rear end of the clamp and engaging the upper surface of the cutter. The stud 30 acts as a pivot in the usual manner so that as the screw 31 is screwed into its socket, the front and rear portions of the clamp will have the customary binding action on the cutter whereby the latter is securely held in place.

In using the plane, the head 20 of the adjusting screw 18 serves as a palm rest. It will be noted that the diameter of the head 20 is at least approximately equal to the width of the cutter. Moreover, the head 20 projects outward beyond the rear extremity of the cutter and is so located with reference to the stock as to form a comfortable support for the palm of the person using the plane. Usually the forefinger will rest in a socket 33 formed in the upper surface of a button 34 riveted to and extending upward from the forward end of the clamp. By this construction, the plane can be grasped and manipulated in a most convenient and satisfactory manner.

In order to make the head 20 of the adjusting screw 18 serve as an effective and comfortable palm rest, said head is not only made of a diameter approximating the width of the stock, but it is also provided with a convex rear surface adapted to conform to the hand of the operator.

It will be manifest that the construction described provides a light, handy plane, which can be readily and cheaply manufactured and is quite strong and durable.

Without limiting myself to the construction shown, I claim:

1. In a plane, the combination of a stock, a frog in said stock, a cutter supported on said frog, an adjusting screw for adjusting said cutter longitudinally, a head for said adjusting screw at the rear of the cutter, of a diameter approximating the width of the stock, and having a convex rear portion or surface to serve as a palm rest for the operator’s hand, a clamp for securing said cutter on the frog, and a button secured to the front end portion of the clamp at the upper surface thereof, said button having an upper surface adapted to support the forefinger of the operator‘s hand, when the latter is supported on the head of said adjusting screw; substantially as described.

2. In a plane, the combination of a stock, a frog in said stock, a cutter supported on said frog, an adjusting screw for adjusting said cutter longitudinally, a head for said adjusting screw at the rear of the cutter, of a diameter approximating the width of the stock, and having a convex rear portion or surface to serve as a palm rest for the operator’s hand, a clamp for securing said cutter on the frog, and a button secured to the front end portion of the clamp, at the upper surface thereof, said button having a socket at its upper surface adapted to receive and conform to the forefinger of the operator’s hand, when the latter is supported on the head of said adjusting screw; substantially as described.

3. In a plane, the combination of a stock with upright side walls, a frog set in between said side walls, and composed of a sheet metal plate having downturned legs at the rear riveted to said side walls, said plate having at the forward portion thereof a struck-out piece or lug parallel to and resting on the sole plate of the stock, said lug or struck-out piece being welded to said sole plate, parallel lugs integral with said frog at the rear portion thereof, and depending therefrom, a cutter supported on said frog, an adjusting screw for said cutter threaded through said parallel lugs, and a clamp for securing said cutter on the frog; substantially as described.

4. In a plane, the combination with a stock having upright side walls, of a frog comprising a sheet metal plate having integral downturned side members secured to side walls of the stock, and integral down-turned lugs for the bit adjusting screw, one of said lugs being struck out from the rear edge of the frog, and the other being struck out of an opening at the intermediate portion of the frog, an adjusting screw threaded through said lugs, a cutter on the frog adjustable by said adjusting screw, and a clamp to secure the cutter on the frog; substantially as described.

In witness whereof I have hereunto set my hand on the 7th day of July 1913.

To all whom it may concern:

Be it known that I, THEODORE G. SELLECK, 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 Bench-Planes, of which the following is a specification.

This invention relates to bench-planes, and its object is to provide a structure which permits the bit to be quickly and easily removed for sharpening, without disturbing the adjusting means thereof.

The invention also has for its object to provide novel and improved means for adjusting the bit.

Other objects and advantages of the invention will be pointed out in the detailed description appearing hereinafter, and in order that the same may be better understood, reference is had to the accompanying drawings, in which —

Figure 1 is a side elevation of a bench plane constructed in accordance with the present invention; Fig. 2 is a longitudinal section on the line 2–2 of Fig. 4; Fig. 3 is a sectional detail showing a slightly modified form of bit; Fig. 4 is a section on the line 4-4 of Fig. 1; Fig. 5 is a section on the line 5–5 of Fig. 1, and Fig. 6 is a section on the line 6–6 of Fig. 4.

Referring specifically to the drawing the stock of the plane is of conventional form, the same comprising a sole 10, side or check-pieces 11, a rear hand grip 12 and a forward knob 13. The sole has a slot 14 through which the bit 15 protrudes.

The bit 15 is carried by a member 16 which is pivotally mounted between the side pieces 11 in a manner to be presently described. By thus pivoting the bit carrier the same may be rotated to take the bit out of the slot 14 as shown by dotted lines in Fig. 1, the bit then pointing upward and being free of the side pieces, in which position it is readily accessible for the purpose of removal. The axis of rotation of the bit carrier is transverse of the stock. The bit carrier 16 tapers toward the end which carries the bit 15, said end having a dovetailed transverse groove 17 in which the bit seats and is held, the rear portion of the bit being shaped to fit in the groove.

The following clamping means for the bit 15 is provided: In the under side of the bit carrier 16 is a threaded aperture to receive a screw 18. This aperture is so located that it intersects the inner end of the groove 17, thus allowing a portion of the back of the bit to extend into the aperture, at the place where the beveled side of the screw head 19 seats, the aperture being countersunlr to accommodate said screw head. By working the screw inward, the beveled side of the head is forced against the back of the bit, and the bit is forced forward to a rigid seat in the groove. The bit can be readily removed by sliding it along the groove, after backing the screw.

Fig. 3 shows a slightly modified form of bit, its inner end having a shoulder 20 which abuts against the end of the bit carrier 16. The bit carrier 16 is a hollow casting having side openings 21. The sides of the bit carrier are flat and parallel, and its width is such that it has a small amount of side play between the side pieces 11. The bit carrier is carried by a yoke, the side arms 22 of which latter seat in longitudinal grooves 23 in the sides of the bit carrier. The connecting bar 24 of the yoke extends across and in spaced relation with the rear end of the bit carrier, or that end which is opposite the end carrying the bit 15. The bar 24 has, midway between its ends, an aperture in which is held an adjusting screw 25 which is threaded through a block 26 carried by the bit carrier, the latter having an aperture 27 to accommodate the inner end of the screw. The screw is held against travel in the direction of its length by its head 27a and a collar or washer 28 located, respectively, on opposite sides of the bar 24. Thus, it will be seen that when the screw is operated, the bit carrier is moved baclr and forth between the arms 22 to regulate the degree of protrusion of the bit through the slot 14.

The yoke is pivoted to the side pieces 11, which provides the hereinbefore described pivotal support for the bit carrier 16. The pivotal connection is made by pivot screws 29 passing through the side pieces and threaded into the arms 22 of the yoke. The heads 30 of the pivot screws are countersunk in the side pieces, and their shanks are devoid of threads where they pass through the side pieces, which enables the bit carrier to be swung without causing the pivot screws to tighten up.

The block 26 seats against the rear end of the bit carrier 16 between outstanding spaced ribs 31 and 32 on the latter, and it is pivoted at one end so that it may swing outward from the end of the bit carrier. The pivotal connection is made by a pin 33 passing through the block and held at its ends in the ribs 31 and 32. The free end of the block is shaped to form a half nut, the thread 34 of which fits in the groove of a worm 35 seating in a recess in the end of the bit carrier, and mounted on a pivot screw 36 carried by the latter. The worm carries a small projecting finger-piece 37 for operating the same.

Upon turning the worm 35 in one direction, by means of the finger-piece 37, the block 26 swings outward from the bit carrier 16, as shown by dotted lines in Fig. 4, and it is swung back toward the bit carrier upon turning the worm in the opposite direction. This movement of the block reults in giving the bit carrier a sidewise tilt to line up the slot 14.

In order to prevent the bit carrier 16 from rocking when the tool is in use, a stout spring latch 38 is provided, the same being secured to the sole 10 and having its free end offset and shaped to snap under the bar 24. When the latch is in holding position, the rear end of the bit carrier cannot swing downward, and it is prevented from swinging upward by the bit 15 engaging the rear wall of the slot 14. Upon disengaging the latch from the yoke bar, the bit carrier may be swung to the dotted line position shown in Fig. 1, for the purpose stated hereinbefore.

I claim:

1. A bench-plane comprising a stock having side-pieces, a yoke pivotally mounted between the side-pieces, a bit carrier carried by the yoke and adjustable in the direction of its length, and means for locking the yoke.

2. A bench-plane comprising a stock having side-pieces, a yoke pivotally mounted between the side-pieces, a bit carrier carried by the yoke, an adjusting screw carried by the yoke and having a threaded engagement with the bit carrier, and means for locking the yoke.

3. A bench-plane comprising a stock having side-pieces, a yoke pivotally mounted between the side-pieces, a bit carrier having longitudinal side grooves, in which the yoke arms seat, means for adjusting the bit carrier in the direction of its length, and means for locking the yoke.

4. A bench-plane comprising a stock having side-pieces, a yoke pivotally mounted between the side-pieces, a bit carrier carried by the yoke and adjustable sidewise and in the direction of its length, and means for locking the yoke.

5. A bench-plane comprising a stock having side-pieces, a yoke pivotally mounted between the side-pieces, a bit carrier carried by the yoke, a pivoted member carried by the bit carrier, an adjusting screw carried by the yoke and having a threaded engagement with the pivoted member, a worm carried by the bit carrier and having a threaded engagement with the free end of the pivoted member, and means for locking the yoke.

6. A bench-plane comprising a stock, a bit carrier, a support for the bit carrier carried by the stock, a pivoted member carried by the bit carrier, an adjusting screw carried by the support and having a threaded engagement with the pivoted member, and a worm carried by the bit carrier, and having a threaded engagement with the free end of the pivoted member.

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

To all whom it may concern:

Be it known that I, WILLIAM E. SPARKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Bench-Planes, of which the following is a full, clear, and exact description.

This invention relates to bench planes and more particularly to a type of plane in which the plane iron or bit is held against the frog or other support by means of a clamp which is adjustable independently of the bit, so that the lower edge of the clamp may be adjusted closer to or farther away from the cutting edge of the bit as required for taking a small or large chip.

The primary object of the present invention is to provide improved and simplified means for adjusting the bit or plane iron longitudinally, and improved and simplified means for giving the bit or plane iron the necessary transversely swinging adjustment to bring the cutting edge thereof into parallelism with the throat of the plane.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, illustrating a preferred embodiment of the invention, Figure 1 is a side elevation of the plane, Fig. 2 is a top plan view thereof, Fig. 3 is an enlarged section on line 3–3 of Fig. 1, Fig. 4 is an enlarged section on line 4–4 of Fig. 2, showing the plane adjusted for taking a small chip, Fig. 5 is a view similar to Fig. 4 but showing the adjustment for rougher work, Fig. 6 is a section on line 6–6 of Fig. 4, Fig. 7 is a detail face view of the clamp, Fig. 8 is a similar view of the clamp from the reverse or under side, Fig. 9 shows a face view and an edge view of the adjusting plate for the clamp, Fig. 10 is a front or top view of the frog, detached, Fig. 11 is a rear or bottom view of the frog, detached, Fig. 12 is a detail section on line 12–12 of Fig. 11, and Fig. 13 is a detail section of the adjusting nut for the clamp.

Referring to the drawings, 20 designates the stock or bed of the plane, which is preferably made of metal of the usual channeled cross-section. The front handle of usual type is indicated at 21 and the ordinary rear handle is shown at 22. The bit or plane iron 23 is clamped against a frog 24 by means of a clamp 25. The bit is moved into and out of a throat 26 in the bed or sole of the stock by means of an adjusting screw 27 carried by the frog 24.

Referring particularly to Figs. 4 and 6, it will be noted that the stock is provided at opposite sides with abutments 28 adjacent the respective side walls. These abutments are slanted off at the top at a proper incline to provide a firm and substantial seat for the lower surface of the frog, and the latter is clamped to the abutments by means of screws 29. At the lower rear part of the frog 24 the latter carries a projecting lug 30 in which the lower end portion of the adjusting screw 27 is freely rotatable. The adjusting screw has a plain bearing in the lug 30 and is prevented from longitudinal movement with respect to said lug by means of collars on the screw at opposite sides of the lug. The lower collar, indicated at 31, is detachably held in place by a pin 32. The opposite or upper end of the adjusting screw 27 has a bearing in a lug 33 projecting from the rear upper portion of the frog and similar to the lug 30. The frog 24 is provided intermediate the lugs 30, 33 with a longitudinal slot 34 which serves as a guide for a bit-adjusting nut 35 having threaded engagement with the shank of the adjusting screw. The nut 35 has a portion projecting into and snugly fitting the slot 34, so that when a milled head 36 on the upper end of the screw 27 is rotated in one or the other direction, the nut 35 will be moved lengthwise of the frog in one or the other direction. This effects the longitudinal adjustment of the bit 23, which is provided at its rear surface with a notch 37 engaged by a pin 38 on the upper surface of the adjusting nut.

The transverse adjustment of the bit, in order to keep its cutting edge in parallelism with the throat, is effected by the following mechanism: At the upper or butt end of the bit or plane iron 23 the latter is provided with a longitudinal slot 39 the opposite side edges of which are adapted to be engaged by a nose 40 of an adjusting lever 41 pivoted to the lug 33 by means of a pin 42. The pin 42 is intermediate of the ends of the lever 41 and said lever is movable in a plane substantially perpendicular to the plane of the frog body and the plane of the bit. The adjusting lever is preferably formed of a sheet metal piece bent into U-shape at one end to afford a gripping portion 43 by means of which the lever may be manipulated. The oscillatory movement of the lever in either direction is not interfered with by the adjusting screw, as the lever is provided with a clearance opening 44 of considerably larger size than the portion of the screw shank which extends through said opening (Fig. 12), and it will be manifest that as the lever 41 is swung on its pivot 42 in one direction, one side of the nose 40 will be engaged by one of the side edges of the slot 39, whereby the bit will be swung transversely of the plane in one direction. If the adjusting lever is moved in the opposite direction the transverse adjusting movement of the bit will be opposite to that first indicated. Hence by proper adjustment of the lever 41 the bit or plane iron can easily be brought to a position in which its cutting edge has the desired parallel relation to the throat 26. Of course, this transverse adjustment of the bit by means of the lever 41 is not effected by the longitudinal adjustment of the bit, for as the latter is moved lengthwise the nose 40 of the adjusting lever will be engaged with the slot 39 at different points in its length. This arrangement of the transverse adjusting means has the advantage that the lever is engaged with the bit in a simple but positive way in all the lengthwise adjustments of the bit, the leverage on the bit being quite sufficient to move it with a slight effort. Moreover, the manipulating portion of the lever is located immediately adjacent and back of the head of the lengthwise adjustment screw, so that it may be reached and adjusted with maximum facility.

The clamp 23 for clamping the bit against the frog is adjusted longitudinally i. e. toward and away from the throat 26, by means of the following mechanism: The clamp has formed on the upper surface thereof opposing guide lugs 44 by means of which the clamp is guided along an adjusting plate 45. This plate has an elongated opening 46 in its body portion or shank to clear the clamping screw 47 which passes through a threaded hole 48 in the clamp 25 and bears at its inner end against the upper surface of the bit. The screw 47 is provided with a milled adjusting head 49. At its lower end the plate 45 is provided with a T-head 50 having on its upper surface a groove 51 extending transversely with respect to the adjusting plate and adapted to engage the under surface of a cross pin or bridge 52 fixed at its respective ends to the side walls or flanges of the stock. The plate 45 lies flat on the upper surface of the clamp 25 against which it is retained by the lugs 44, and when the T-head 50 of the plate has been engaged with the under portion of the cross pin 52 in the manner stated, the screwing in of the clamping screw 47 will obviously secure the clamp and the bit tightly in place, inasmuch as the cross pin 52 will act as a pivot about which the clamp is moved to bind its lower edge against the lower portion of the bit and the clamping screw 47 against the intermediate portion of the bit. The plate 45 therefore serves as an attachment for the clamp by means of which the latter may be placed in pivotal relation to the cross pin when the clamping screw 47 is properly adjusted, the clamp and adjusting plate being readily detachable from assembled position when the clamping screw is released from its binding engagement with the bit. At its upper end the plate 45 is provided with a threaded extremity 53 which engages interior screw threads of a milled adjusting nut 54 freely rotatable with respect to the clamp but movable longitudinally therewith. In the form shown, the hollow adjusting nut 54 is detachably seated in a boss or socket portion 55 formed integral with the upper end portion of the clamp. Beneath the boss 55, the under portion of the clamp is cut away at 55a to permit the nut 54 to be detachably seated in the boss, in which position a collar 56 on the nut is engaged with a groove 57 in the boss in order to prevent longitudinal movement of the nut in the latter when the parts are assembled. ln assembling, the nut is placed in its seat in the boss and the threaded extremity 53 of the adjusting plate is then engaged with the interior screw threads of the nut. When the nut is rotated in such a direction as to pull the threaded extremity or shank 53 into the same, the displacement of the nut from its seat will be effectively prevented and as the nut is rotated in one or the other direction the clamp 25 will be obliged to move toward or away from the throat, as the case may be, inasmuch as the plate 45 is fixed relatively to the stock by means of its engagement with the cross pin 52.

It will therefore be understood that with the construction described, the bit and the clamp may be easily moved into any desired relative positions. When a fine chip is to be taken, the screw 27 for effecting the longitudinal movement of the bit is so manipulated as to project the bit only to a very slight extent beyond the lower surface of the bed, and the nut 54 will be so manipulated as to move the lower edge of the clamp 25 into very close proximity to the cutting edge of the bit, as shown in Fig. 4. This adjustment of the clamp will have a certain effect in producing a fine chip and it will also effectively prevent chattering. In the position shown in Fig. 5, the plane is adjusted to take a large chip, the bit being projected farther out of the throat and the clamp being farther retreated from the edge of the bit. However, I do not claim the mechanism for clamping the bit on the frog, as the same forms no part of my invention.

Without limiting myself to the precise construction shown, I claim:

1. ln a plane, the combination of a stock, a frog detachably set in said stock and having a longitudinal slot extending through said frog, an adjusting screw substantially parallel to the geometrical plane of the frog at the rear of the latter, means forming a bearing for the lower end of said adjusting screw, an integral lug projecting rearwardly and downwardly from said frog at the upper rear portion of the latter, and serving as a bearing for the upper end portion of said adjusting screw, a nut threaded and traveling on said adjusting screw at the rear of the frog, a bit clamped on said frog, a part on said nut extending forwardly and upwardly into the slot of said frog, and operatively engaging said bit at a point intermediate of the ends of said bit and intermediate of the end bearings of said screw, and a milled adjusting head carried by said screw above the upper bearing; substantially as described.

To all whom it may concern:

Be it known that I, BERTEL F. VAUGHAN, a citizen of the United States, residing in the borough of West Haven and county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Adjustable Knobs for Planes, of which the following is a full, clear, and exact description.

This invention relates to an improved construction of adjustable grip member or knob for planes or other devices where it is desired to set a knob or like member in any of a number of different inclined positions.

One of the objects of the invention is the provision of a grip member for planes, which is universally adjustable i. e. which can be tilted both transversely and longitudinally of the plane stock, and clamped in the position in which it will serve the operator’s purpose most conveniently. A tilting knob such as contemplated by my invention, can be used to particular advantage on smoothing planes, as it will enable the operator to grasp the plane in a manner conducive to the most accurate work.

Another object of the invention is to provide improved means for clamping the knob in its various adjustments. More particularly, it is aimed to provide a construction in which the knob may be released by turning it in one direction after which it may be swung into another position and clamped in that position by turning it in a direction opposite to that first mentioned.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a smoothing plane having a knob embodying my invention, Fig. 2 is an enlarged front elevation of Fig. 1 with certain parts omitted, Fig. 3 is a section on line 3–3 of Fig. 2, Fig. 4 is a top plan view of the forward end of the stock with the knob proper removed, Fig. 5 is a bottom view of the knob base, detached, Fig. 6 is a bottom plan view of the knob proper, and Fig. 7 is a detail view of the clamping bolt and nut.

Referring to the drawing, I have shown an adjustable knob 10 as applied to a smoothing plane having a stock 11, bit or cutter 12 and handle 13. The knob proper is of more or less usual outer configuration except at the bottom, which is made concave, as shown at 10a in Fig. 6, in order to fit the convex upper surface 14 of a knob base 15 on the bed or sole 16 of the stock. The base 15 is detachably applied to the upper surface of the bed or sole 16 of the stock by means such as fastening screws 15a. The base, which is formed as a portion of a sphere, has a diameter somewhat greater than that of the lower portion of the knob which rests on it, and at the center of the base the same is provided with a cruciform slot 17. A clamping bolt 18 has a head 19 located in the space beneath the base 15 and a shank 20 passing upward out of the slot 17 and through the knob. The head 19 of bolt 18 is too large to pass through the slot 17, and assemblage is effected by extending the shank of the screw upward through the base before the latter is secured to the stock by the screws 15a The upper portion of the knob is counterbored to receive a cylindrical nut 21 having interior screw threads engaging the threads 18a on the end of the shank 20.

The under surface of the base 15 is provided with a plurality of concentric ribs 22, and the upper surface of the screw head 19 is provided with a plurality of teeth 23 adapted to engage these ribs and also to engage the corners of the slot 17 whereby the knob may be tightly clamped in different adjustments when the nut 21 is screwed up sufficiently on the bolt 18.

It will be understood, that when the knob has its axis directed perpendicularly to the plane of the bed 16, the teeth 23 of the head 19 will interlock with the corners 17a of the slot 17 when the nut 21 is screwed up tightly on the bolt 20. To release the knob from this position, it is usually merely necessary to turn it in an anti-clockwise direction which will release the nut 21 by the frictional fit between said nut and its socket in the knob. Upon release of the clamping bolt the knob may then be shifted into any of a large number of inclined positions with the shank 20 of the bolt passing through the middle of the slot or through any one of the four corners thereof, and with the head 19 of the bolt engaged with the corners 17a of the slot or with the ribs 22. When the knob has been moved to the desired angular position, it may be tightened in that position by turning it in a clockwise direction; which movement will tighten up the nut 21 by virtue of the frictional fit of the latter in its socket in the knob. It will thus be understood that by the construction described, the knob is capable of universal adjustment. The dotted lines in Fig. 1 show two different adjustments of the knob in a direction lengthwise of the plane, and in Fig. 2, two different adjustments transversely of the plane are represented.

In case an especially tight clamping of the knob is desired, the nut 21 may be screwed up by a screw-driver fitting a nick 21a in said nut, and this screw-driver nick is also useful where difficulty is encountered in releasing the knob by hand in the manner described.

I do not limit myself in all aspects of the invention to a knob located in front of the cutter of the plane, and in some aspects of the invention it is not essential that a tilting knob located in front of the cutter be adjustable both transversely and longitudinally of the plane stock.

Without limiting myself to the construction shown, I claim:

1. The combination with a plane, of a universally adjustable grip member therefor; substantially as described.

2. The combination with a plane, of a tiltable knob therefor and means to clamp and release the knob by a turning movement thereof; substantially as described.

3. The combination with a plane stock, of a knob applied to said stock and tiltable transversely of the stock and longitudinally thereof; substantially as described.

4. The combination with a plane, of a detachable knob, and means for clamping the knob to the plane in any of a number of positions wherein the knob is tilted either transversely or longitudinally of the plane; substantially as described.

5. In a plane, a universally adjustable tilting knob, and means to clamp and release the knob; substantially as described.

6. In a plane, the combination of a stock, a cutter in the stock, a handle at the rear of the cutter, a tiltable knob in front of the cutter, and means to clamp and release the knob by a turning movement thereof; substantially as described.

7. The combination with a plane stock, of a concave-convex member detachably secured to the bed of said stock and having a slot therein, a knob resting on the upper convex surface of said member, a clamping device having a head confined between the bed of the stock and the under concave surface of said member, and provided with a shank passing upward through said slot into said knob, and a nut threaded on said shank to clampbthe knob in position; substantially as described.

In witness whereof, I have hereunto set my hand on the 30th day of July 1913.

To all whom it may concern:

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

My invention relates to that class of planes commonly termed “dado” planes, the main function of which is to cut a groove across a grain of a piece of wood. Such a plane should be so constructed as to effectively score the wood ahead of the cutter.

One of the objects of my invention is to provide a simple and improved device for performing this operation.

Another object is to provide an improved plane body, so designed as to reliably carry the various parts thereon, said parts being so placed and spaced as to render the plane easy to operate, and under perfect control at all times.

In the accompanying drawings: Figure 1 is a perspective view of my improved plane. Fig. 2 is a plan view thereof. Fig. 3 is a section on the line 3–3. Fig. 4 is a section on the line 4–4. Fig. 5 is a perspective view of the scoring tool. Fig. 6 is a perspective view of the cutter.

The plane body or frame is formed integrally of cast iron, and has a central web section and lateral flanges so disposed as to make the frame comparatively light, and yet of maximum strength, the said several parts of the plane body or frame being so disposed or distributed, so a.s to afford a high degree of stability by a comparatively small amount of material.

1 represents the web portion, which is, as seen, comparatively thin, and occupies a position centrally in the plane body, and in the same plane as the runner or sole, except near the center, where the said web is offset sufficiently to form guide channels for the scoring tool and cutters.

2 represents the scoring tool, and 3 represents the cutter. The scoring tool is adjustably mounted in a vertical guide-way, and in line with the runner portion indicated at 4, the runner portion is interrupted intermediate its length to allow the effective ends of the scoring tool 2 and the cutter 3 to project down to the working position. At the rear of the plane body, the web section is extended upwardly to form the handle portion, the handle portion being bounded by the flanges 5, 6, 7 and 8, which extend on opposite sides of the web, these flanges being suitably rounded to at the hand.

9 is a circular opening located between the rear ends of the scoring tool 2 and the cutter 3, the said opening being bounded by a flange integrally connected with the web, and with a bridge flange 10 connected with the upper end of the handle. This opening is designed to receive the thumb of the left hand, while the right hand engages the handle. By this construction, the user is afforded a convenient and effective means for applying both hands to the tool in such a manner as to have the tool under complete control at all times, whereby it may be used with the greatest ease, facility and accuracy. Extending forward from the flange surrounding the thumb opening 9 is a flanged portion 11, which extends down to the toe of the plane. Extending rearwardly from the flange around the thumb opening 9 is a flanged portion 12, which merges into the fianged portion 13, directly in front of the hand opening, just forward of the handle. The flanged portion 3 extends forwardly to a point just to the rear of the cutter 3, where it is interrupted to allow the scoring tool 2 and cutter to pass. This flange is then continued onwardly, as at 8a, the bottom of the flange 8a being in the same plane with the bottom of the flange 8.

The scoring tool and cutter may be adjustably held in place by any suitable means, such as screws 14–14, which pass through slots in the said tools and take a threaded engagement in the web of the plane body adjacent thereto.

15 is an adjustable depth gage, which may be mounted just ahead of and close to the scoring tool 2.

The scoring tool is made of substantially the same width or thickness as the cutter, and is provided with a deep groove 2a to provide two beveled scoring edges designed to score the wood in advance of the cutter along two lines coincident with the overall width of the cutter, so that as the cutter proceeds into the wood, it will be prevented from chipping the same, and will make a clean cut of the full width of the score lines. The cutter should be of a width or thickness slightly in excess of the thickness of the runner 4, so that said runner 4 will not jam in the groove, and yet will be sufficiently steadied thereby to guide the cutter.

It will be observed that the flanges by extending on both sides of the web, reinforce the same and prevent buckling. Also that the lower flange forms a substantially flat sole below which extends the runner portion which is divided by the throat where the cutters are located, the rear end of the front sole section and the front end of the rear sole section affording seats for the cutters. Inasmuch as the runner portion is in the plane of the web, that is to say, is approximately centrally located relatively to the sole, both sides of the runner portions may be properly smoothed off or machined so that the releasing of the surface tension on one side of the runner portion is compensated by the releasing of surface tension on the opposite side thereof thus avoiding any tendency to buckling strain which might be present if the runner were machined on only one side.

What I claim is:

1. In a plane, an integral body casting comprising a longitudinal web section, lateral flange reinforcements bordering said web section and extending on each side thereof, the lower flange forming a flat sole, a relatively thin runner depending below said sole and in the plane of the web, said runner being separated intermediate its length to form a front runner section and a rear runner section, said runner sections being bridged and reinforced by said flanged web.

2. In a plane, an integral body casting comprising a longitudinal web section, lateral flange reinforcements bordering said web section and extending on each side thereof, the lower flange forming a flat sole, a relatively thin runner depending below said sole and in the plane of the web, said runner being separated intermediate its length to form a front runner section and a rear runner section, said runner sections being bridged and reinforced by said flanged web, two cutter guide grooves in the body casting in the plane of the runner, both grooves leading to the space separating the front and rear runner sections, the rear end of the front runner section and the forward end of the rear runner section forming cutter seats.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Bench-Planes, of which the following is a full, clear, and exact description.

This invention relates to bench planes and more particularly to a type of plane in which the plane iron or bit is held against the frog or other support by means of a clamp which is adjustable independently of the bit, so that the lower edge of the clamp may be adjusted closer to or farther away from the cutting edge of the bit as required for taking a small or large chip.

The primary objects of the present invention are to provide improved and simplified means for giving the clamp a positive adjusting movement in either direction i. e. toward or away from the cutting edge of the bit; to furnish clamp adjusting means which permits the clamp to be easily placed in and removed from its assembled position; and to provide certain improved and simplified features in connection with the means for adjusting the bit or plane iron longitudinally and transversely.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, illustrating a preferred embodiment of the invention, Figure 1 is a side elevation of the plane, Fig. 2 is a top plan view thereof, Fig. 3 is an enlarged section on line 3–3 of Fig. 1, Fig. 4 is an enlarged section on line 4–4 of Fig. 2, showing the plane adjusted for taking a small chip, Fig. 5 is a view similar to Fig. 4 but showing the adjustment for rougher work, Fig. 6 is a section on line 6–6 of Fig. 4, with certain parts omitted, Fig. 7 is a detail face view of the clamp, Fig. 8 is a similar view of the clamp from the reverse or under side, Fig. 9 shows a face view and an edge view of the adjusting plate for the clamp, Fig. 10 is a front or top view of the frog, detached, Fig. 11 is a rear or bottom view of the frog, detached, Fig. 12 is a detail section on line 12–12 of Fig. 11, and Fig. 13 is a detail section of the adjusting nut for the clamp.

Referring to the drawings, 20 designates the stock or bed of the plane, which is preferably made of metal of the usual channeled cross-section. The front handle of usual type is indicated at 21 and the ordinary rear handle is shown at 22. The bit or plane iron 23 is clamped against a frog 24 by means of a clamp 25. The bit is moved into and out of a throat 26 in the bed or sole of the stock by means of an adjusting screw 27 carried by the frog 24.

Referring particularly to Figs. 4 and 6, it will be noted that the stock is provided at opposite sides with abutments 28 adjacent the respective side walls. These abutments are slanted off at the top at a proper incline to provide a firm and substantial seat for the lower surface of the frog, and the latter is clamped to the abutments by means of screws 29. At the lower rear part of the frog 24 the latter carries a projecting lug 30 in which the lower end portion of the adjusting screw 27 is freely rotatable. The adjusting screw has a plain bearing in the lug 30 and is prevented from longitudinal movement with respect to said lug by means of collars on the screw at opposite sides of the lug. The lower collar, indicated at 31, is detachably held in place by a pin 32. The opposite or upper end of the adjusting screw 27 has a bearing in a lug 33 projecting from the rear upper portion of the frog and similar to the lug 30. The frog 24 is provided intermediate the lugs 30, 33 with a longitudinal slot 34 which serves as a guide for a bit-adjusting nut 35 having threaded engagement with the shank of the adjusting screw. The nut 35 has a portion projecting into and snugly fitting the slot 34, so that when a milled head 36 on the upper end of the screw 27 is rotated in one or the other direction, the nut 35 will be moved lengthwise of the frog in one or the other direction. This effects the longitudinal adjustment of the bit 23, which is provided at its rear surface with a notch 37 engaged by a pin 38 on the upper surface of the adjusting nut. The transverse adjustment of the bit, in order to keep its cutting edge in parallelism with the throat, is effected by the following mechanism: At the upper or butt end of the bit or plane iron 23 the latter is provided with a longitudinal slot 39 the opposite side edges of which are adapted to be engaged by a nose 40 of an adjusting lever 41 pivoted to the lug 83 by means of a pin 42. The pin 42 is intermediate of the ends of the lever 41 and said lever is movable in a plane substantially perpendicular to the plane of the frog body and the plane of the bit. The adjusting lever is preferably formed of a sheet metal piece bent into U-shape at one end to afford a gripping portion 43 by means of which the lever may be manipulated. The oscillatory movement of the lever in either direction is not interfered with by the adjusting screw, as the lever is provided with a clearance opening 44 of considerably larger size than the portion of the screw shank which extends through said opening (Fig. 12), and it will be manifest that as the lever 41 is swung on its pivot 42 in one direction, one side of the nose 40 will be engaged by one of the side edges of the slot 39, whereby the bit will be swung transversely of the plane in one direction. If the adjusting lever is moved in the opposite direction the transverse adjusting movement of the bit will be opposite to that first indicated. Hence by proper adjustment of the lever 41 the bit or plane iron can easily be brought to a position in which its cutting edge has the desired parallel relation to the throat 26. Of course, this transverse adjustment of the bit by means of the lever 41 is not affected by the longitudinal adjustment of the bit, for as the latter is moved lengthwise the nose 40 of the adjusting lever will be engaged with the slot 39 at different points in its length. This arrangement of the transverse adjusting means has the advantage that the lever is engaged with the bit in a simple but positive way in all the lengthwise adjustments of the bit, the leverage on the bit being quite sufiicient to move it with a slight effort. Moreover, the manipulating portion of the lever is located immediately adjacent and back of the head of the lengthwise adjustment screw, so that it may be reached and adjusted with maximum facility.

The clamp 23 for clamping the bit against the frog is adjusted longitudinally i. e. toward and away from the throat 26, by means of the following mechanism: The clamp has formed on the upper surface thereof opposing guide lugs 44 by means of which the clamp is guided along an adjusting plate 45. This plate has an elongated opening 46 in its body portion or shank to clear the clamping screw 47 which passes through a threaded hole 48 in the clamp 25 and bears at its inner end against the upper surface of the bit. The screw 47 is provided with a milled adjusting head 49. At its lower end the plate 45 is provided with a T-head 50 having on its upper surface a groove 51 extending transversely with respect to the adjusting plate and adapted to engage the under surface of a cross pin or bridge 52 fixed at its respective ends to the side walls or flanges of the stock. The plate 45 lies flat on the upper surface of the clamp 25 against which it is retained by the lugs 44, and when the T-head 50 of the plate has been engaged with the under portion of the cross pin 52 in the manner stated, the screwing in of the clamping screw 47 will obviously secure the clamp and the bit tightly in place, inasmuch as the cross pin 52 will act as a pivot about which the clamp is moved to bind its lower edge against the lower portion of the bit and the clamping screw 47 against the intermediate portion of the bit. The plate 45 therefore serves as an attachment for the clamp by means of which the latter may be placed in pivotal relation to the cross pin when the clamping screw 47 is properly adjusted, the clamp and adjusting plate being readily detachable from assembled position when the clamping screw is released from its binding engagement with the bit. At its upper end the plate 45 is provided with a threaded extremity 53 which engages interior screw threads of a milled adjusting nut 54 freely rotatable with respect to the clamp but movable longitudinally therewith. In the form shown, the hollow adjusting nut 54 is detachably seated in a boss or socket portion 55 formed integral with the upper end portion of the clamp. Beneath the boss 55, the under portion of the clamp is cut away at 555 to permit the nut 54 to be detachably seated in the boss, in which position a collar 56 on the nut is engaged with a groove 57 in the boss in order to prevent longitudinal movement of the nut in the latter when the parts are assembled. In assembling, the nut is placed in its seat in the boss and the threaded extremity 53 of the adjusting plate is then engaged with the interior screw threads of the nut. When the nut is rotated in such a direction as to pull the threaded extremity or shank 53 into the same, the displacement of the nut from its seat will be effectively prevented and as the nut is rotated in one or the other direction the clamp 25 will be obliged to move toward or away from the throat, as the case may be, inasmuch as the plate 45 is fixed relatively to the stock by means of its engagement with the cross pin 52. It will therefore be understood that with the construction described, the bit and the clamp may be easily moved into any desired relative positions. When a fine chip is to be taken, the screw 27 for effecting the longitudinal movement of the bit is so manipulated as to project the bit only to a very slight extent beyond the lower surface of the bed, and the nut 54 will be so manipulated as to move the lower edge of the clamp 25 into very close proximity to the cutting edge of the bit, as shown in Fig. 4. This adjustment of the clamp will have a certain effect in producing a fine chip and it will also effectively prevent chattering. In the position shown in Fig. 5, the plane is adjusted to take a large chip, the bit being projected farther out of the throat and the clamp being farther retreated from the edge of the bit. It will be understood from the foregoing that when the clamp has once been adjusted, it may be removed from the stock and then returned to its position in the stock without altering its original adjustment. Hence, it is possible to remove the bit for sharpening and to replace it in position without changing the clamp adjustment relative to the throat.

While the foregoing description is necessarily a detailed one in so far as it concerns the particular embodiment of my invention selected for illustration and description, it will be apparent that numerous modifications of the construction may be adopted within the scope of the appended claims.

I do not claim the mechanism for adjusting the bit or cutter, as said mechanism forms the subject of an application filed by William E. Sparks, on May 16, 1914, Serial No. 839,117.

What I claim is:

1. In a plane, the combination of a stock having a throat, a bit projecting into said throat, a pivotally movable clamp for the bit having a clamping screw to engage the upper surface of the bit, a bridge piece carried by the stock, and a lengthwise adjusting device for the clamp having pivotal engagement with said bridge piece whereby the clamp is moved pivotally about the bridge piece as said screw is adjusted; substantially as described.

_________________

To all whom it may concern:

Be it known that I, HARVEY M. WOOD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Bench-Plane, of which the following is a specification.

The object of this invention is to protect the cutting edge of the blade during the backward stroke of the plane and while standing idle on its sole, this result being attained by use of a heel-piece yieldingly projecting through and beyond the sole and serving to normally uphold the same above the table top.

This application is a division of my co-pending application for patent on bench plane, Serial No. 401,341, filed Nov. 8, 1907.

The accompanying drawings illustrate the invention.

Figure 1 is a side elevation partly in mid-section, showing the details of the heel-piece and the symmetrical mechanism for operating the same. Fig. 2 is a similar view showing a modification of the mechanism for operating the heel-piece. Fig. 3 is a reduced plan of the bottom of either of the planes shown in Figs. 1 and 2.

Numeral 1 refers to the shoe of an ordinary plane having a blade 2, hollow handle 3, sole 4, and yieldingly extended retractible heel-piece 5, the latter projecting normally through aperture 6 and extending substantially across the sole. A spring 8, fixed to the shoe and engaging notch 9 in the heel-piece normally projects the heel-piece through the sole so that when the plane rests loosely upon the work or on the bench top 7, or is being drawn backward over the same, the heel and the cutting edge will be raised off the work as shown in the drawings, thus saving the cutting edge from all unnecessary contact and preserving its keenness. On the forward or planing stroke, however, it is essential that the cutting edge come onto the work immediately and manually operated means are provided whereby the forward pressure of the workman’s hand in the operation of planing, will automatically retract the heel-piece. With this object in view, there is provided a rear handle section or palm piece 10, suitably connected with the heel-piece to retract it into the shoe and permit the sole and cutting edge to come down onto the work. The heel-piece 5 may be unitarily constructed with, or may be attached by screws 13 to a carrier block 14 having uprights 15 and vertically movable in the shoe; the uprights being provided with vertical slots 17 running on a pintle 18 rigidly mounted in the handle and thus assisting in guiding the carrier and heel-piece.

In the form shown in Fig. 1, linkage is provided for retracting the heel-piece. The link 22 is pivotally mounted at one end on the palm piece 10 and is pivotally connected at the other end by pin 23 to a bell-crank 24 that is pivotally supported on the handle by means of the pivot 25, and that is provided at its operating end with a forked arm 26, the prongs of which cooperate with pin 27 to retract the heel-piece and carrier. By this means the heel-piece will be automatically retracted in an obvious manner by the forward pressure of the workman’s hand on the palm piece during the cutting stroke.

In the form shown in Fig. 2, the palm piece 10 carries a downwardly and forwardly inclined cam member 12, adjacent which the uprights are provided with a revolubly mounted cam follower 16 adapted to cooperate with the cam member 12 to raise the carrier block and heel-piece when the palm piece 10 is pressed forward. A latch comprising a finger piece 19 and stop 20 is provided to engage a notch 21 of the heel-piece to hold the heel-piece retracted with its face flush with the sole. When the heel-piece is latched, the plane operates like an ordinary plane during both the forward and return strokes.

I claim :–

1. In a plane the combination of a shoe, a blade, a handle behind said blade, said handle being rigidly mounted on said shoe, and said handle having a rear member movably mounted, a heel-piece arranged to normally project beyond the shoe, and means connecting the said rear member of the handle with the heel-piece and adapted to retract the said heel-piece when the rear section of the handle is moved.

2. In a plane the combination of a shoe, a blade, a spring operated heel-piece arranged to normally project beyond the shoe, a handle behind said blade, said handle being rigidly mounted on said shoe, and said handle having a movably mounted rear section, means connecting the said rear section of the handle with the heel-piece and adapted to retract the said heel-piece when the rear section of the handle is moved, and means for holding said heel-piece in its retracted position.

3. In a plane, the combination of a shoe, a blade, a hollow handle having a rear section pivotally mounted, a spring-operated heel-piece adapted to normally project beyond the shoe and mechanism in the hollow of the handle connecting the rear section of the handle with the heel-piece and adapted to retract the heelfpiece when the rear sec-
tion of the handle is moved.

4. In a plane the combination of a shoe, a blade, a hollow handle having a rear section pivotally mounted, a spring operated heel-piece adapted to normally project beyond the shoe, and link mechanism supported in the hollow of the handle and connecting the rear section of the handle with the heel-piece and adapted to retract the heel-piece when the rear section of the handle is moved.

5. In a plane the combination of a shoe, a blade, a hollow handle having a rear section pivotally mounted, a carrier riding in the hollow of the handle, a heel-piece mounted on the carrier and adapted to normally project through and beyond the shoe, and means in the hollow of the handle connecting the rear section of the handle with the carrier and adapted to retract the carrier and heel-piece by motion of the rear section of the handle.

6. In a plane the combination of a shoe, having a sole, a blade, a hollow handle having a rear section pivotally mounted, a heel-piece adapted to normally project beyond the sole, a bell-crank mounted within the handle and having a forked arm, a link connecting one arm of the bell-crank with the rear section of the handle, and a pin mounted on the heel-piece and cooperating with the forked arm of the bell-crank to be raised by the same.

7. In a plane, the combination with a shoe, a blade and a handle behind said blade, of a spring-operated heel-piece carried by said handle and arranged to lift the heel of the plane, and manually operated means for retracting said heel-piece.

8. In a plane, the combination with a shoe, a blade and a handle behind said blade, of a spring-operated heel-piece carried by said handle and arranged to lift the heel of the plane, means for retracting said heel-piece, and means for holding said heel-piece in its retracted position.

9. A plane comprising a sole, a handle fixed to said sole and provided with a movable palm-piece, and a heel piece operatably connected to the palm-piece and normally below the plane of the sole and adapted to be raised by movement of said palm-piece.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 28th day of September 1912.

To all whom it may concern:

Be it known that I, WILLIAM E. SPARKS, a citizen of the United States, residing in the city and county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and enact description.

This invention relates to planes, and more particularly to reversible rabbet planes.

The plane selected for illustration is of the type known as a show-case plane, it being adapted to cut the rabbets of showcases by movement in either direction.

The primary object of the invention is to provide a simple, efficient form of reversible rabbet plane in which reversal may be effected without adjustment of the cutting mechanism. To this end, the plane is provided with two cutters having a novel relation to each other and to the body or stock and clamped on the stock in a novel manner.

The invention also aims to improve certain general and detail features of construction in planes of the class to which my invention relates.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawing, Figure 1 is a side elevation of a plane embodying my improvements, Fig. 2 is a top plan view of the same, Fig. 3 is a front end view, Fig. 4 is a section on line 4–4 of Fig. 2, Fig. 4a is a section on line 4a–4a of Fig. 2, Fig. 5 is a fragmentary plan view of the stock body with the cutters and clamp omitted, Fig. 6 is a bottom plan view of Fig. 5, and Fig. 7 shows the clamp in plan and in rear elevation.

Referring to the drawing, the stock or body 10 is formed of a flat metal plate having a knob or handle 11 projecting upward from the rear end. In advance of the knob 11 the body is provided with a raised portion or enlargement 12 having intersecting grooves 13, 14. The groove 13 is deeper than the groove 14 and said grooves lead completely to the forward edge of the stock at the corners thereof, as shown at 13a and 14a respectively in Fig. 5. Secured to the forward edge of the stock or body at the median portion thereof is a transverse nose piece 15 having an extension 16 opposing the open end 13a of the groove 13 and forming in connection therewith a throat 17 into which projects the forward cutting end of a cutter 18 located in the groove 13. At the opposite end of the nose piece 15 the same is provided with an extension 19 forming in connection with the forward extremity 14a of the groove 14, a throat 20 directed transversely of the plane in line with the throat 17 but at the opposite side of the plane, which throat 20 receives the cutting edge of a cutter 21. This cutter 21 is located in the groove 14 and its rear portion passes over and across the rear portion of the cutter 18. Both cutters 18 and 21 fit snugly in the corresponding grooves 13 and 14, and while the axes of the cutters are directed at an angle to a line extending transversely of the plane, the forward cutting edges of said cutters are substantially parallel to such a line as shown in Fig. 2.

Both cutters are clamped in position in the stock by the same clamping means. In the form shown, I employ a clamp 21a secured to the stock or bed plate 10 by a clamping screw 22. By preference, the screw 22 engages a threaded socket 23 tapped in the stock or bed plate at a point slightly in front of the intersection of the grooves 13, 14. The clamp 21a is formed of a metal plate extending transversely of the plane and having downturned extremities 24. One of these extremities 24 is adapted to rest upon the cutter 18 at a point slightly in the rear of the cutting edge, and the other downturned extremity 24 of the clamp is adapted to engage the cutter 21 in a similar location so that as the clamp screw 22 is screwed into its socket 23, the clamp will be forcibly brought down on both cutters so as to hold them securely in position.

In using the plane, the cutter 18 will be employed for cutting when the plane is moved in one direction, and when it is desired to reverse the plane and move it in the opposite direction, it is simply necessary to turn it around and use the cutter 21. Hence no adjustment of the cutters is necessary in reversing the plane.

In planing in corners or similar locations, the nose piece 15 may be entirely removed if desired, and this may be effected by removing a single screw 25 which passes through said nose piece into the forward edge of the bed plate. This single screw will hold the nose piece securely on the end of the bed plate in connection with a tongue and groove joint 26 formed at the meeting surfaces of the nose piece and bed plate, as shown in Figs. 1 and 4.

Without limiting myself to the construction shown, I claim:

1. In a plane, a bed plate or stock having transversely arranged throats at the opposite forward corners thereof, there being grooves in said bed plate extending rearwardly from said throats and intersecting each other, cutters adapted to fit said grooves, clamping means for said cutters located in front of the intersection of said grooves; and a knob fixed on said bed plate at the rear of such intersection; substantially as described.

2. In a plane, a bed plate having intersecting grooves, one of said grooves being deeper than the other at the point where said grooves intersect, cutters located in said grooves and overlapping each other, and a single means for clamping both cutters in said grooves; substantially as described.

3. In a plane, a bed plate having cutter-receiving grooves extending to one edge thereof, and a detachable nose piece applied to said edge of the bed plate and forming in connection with the ends of said grooves, throats for the cutting ends of the cutters; substantially as described.

4. In a plane, the combination of a bed plate or stock having transversely arranged throats at the opposite forward corners thereof, there being grooves in said bed plate extending rearwardly from said throats, cutters fitting said grooves, a single clamp to secure both of said cutters in the respective grooves at the same time, and a knob fixed to the bed plate at the rear of the cutters; substantially as described.

5. In a plane, the combination of a bed plate or stock, having intersecting cutter-receiving grooves terminating at the forward corners thereof, one of said grooves being deeper than the other at the point of intersection, cutters fitting the respective grooves, a single clamp for securing the cutters in the respective grooves, in overlapping relation, and a single detachable nose piece cooperating with the forward ends of both grooves to form throats for the cutters; substantially as described.

6. In a plane, a bed plate having cutter-receiving grooves on the upper surface thereof extending to one edge of the bed plate, a nose piece detachably secured to said edge of the bed plate between said grooves, and extensions on said nose piece located in front of the groove ends; substantially as described.

7. In a plane, the combination of a substantially flat bed plate, cutters projecting beyond the front edge of said bed plate at different points, means to secure said cutters on said bed plate, and a nose piece detachably secured to the front edge of the bed plate between said cutters and forming, in conjunction with the bed plate, throats for both cutters; substantially as described.

8. In a plane, the combination of a stock, crossed overlapping cutters having their cutting edges arranged at the respective forward corners of the stock, a single clamp for clamping both cutters on the stock at the same time, and a knob hired to the rear portion of the stock; substantially as described.

In witness whereof, I have hereunto set my hand on the 9th day of July 1913.

To all whom it may concern:

Be it known that I, JOHN SMITH, a citizen of the United States, and a resident of Pooler, in the county Of Chatham and State of Georgia, have invented a new and Improved Plane, of which the following is a full, clear, and exact description.

This invention relates to woodworking tools and has particular reference to the construction of carpenters’ planes whereby a tool of this character may be adjusted or modified in size and thereby made to serve as a substitute for several different sizes of planes commonly required by a carpenter.

The primary object of the invention, therefore, is to provide a tool of the class indicated which is adapted by the provision of one or more extensions to take the place of a set of planes including a smoothing or block plane, a jack plane, a fore-plane and a jointer.

The foregoing and other objects of the invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in all the views, and in which —

Figure 1 is a longitudinal section invention arranged as a jointer; Fig. 2 is a plan view of the same; and Fig. 3 is view of the rear extension detached.

The several parts of the device may be made of any suitable materials, and the relative sizes and proportions, as well as the general design of the mechanism, may be varied to a considerable extent without departing from the spirit of the invention hereinafter more fully set forth and specifically claimed.

A device made in accordance with this invention comprises a head or body 10 having a throat or mouth 11 for the accommodation of the usual bit and frog (not shown), and nsually provided also with a handle 12 and a knob 13, especially when made of metal. As is usual in the construction of metal planes there are provided vertical side flanges 14 extending from one end to the other of the body 10 and between which the supporting means 15 for the bit are arranged.

The body 10 to which the handle and knob are connected permanently constitutes what is commonly termed a block or smoothing plane, and in order to constitute such of the a plan implement into a jack plane an extension 16 is added to the front end thereof. Said extension 16 comprises a flat portion constituting an extension of the base of the body 10 and is provided on its lateral edges with reinforcement ribs 17 each having an arm 18 extending rearwardly in close engagement with the inner surface of the adjacent flange 14. Said arms span the joint between the main base and the extension and adjacent their rear ends I provide means to temporarily lock the extension to the front end of the body 10. As shown herein said locking means comprises a pair of studs 19 extending inwardly from the inner surfaces of the flanges 14 just above the rear ends of the arms 18. Preferably said arms are adapted to slip directly beneath and in close contact with said studs, as shown in Fig. 1. I also provide spring catches 20 which engage over the studs 19 and serve to prevent longitudinal displacement of the extension 16. The studs serve, therefore, directly to prevent the rear ends of the arms from tilting up and through the catchers 20 they prevent longitudinal movement, as above set forth. The principal strain, however, upon the extension would tend to be upward or in a direction to cause the front end of the extension to be elevated above the plane of the bottom of the implement. This tendency, however, is resisted effectively by means of a lip 21 extending into a rabbet 21′ formed across the end of the lower surface of the body 10. Said lip and rabbet are provided preferably with right angles and hence will not interfere with the aforesaid slidable movement of the extension when putting it in place. Lateral distortion or twisting of the parts is prevented by the fact that the arms have close engagement with the inner surfaces of the flanges 14 and also by the fact of the shoulders 22 cooperating with the ends of said flanges.

In order to constitute the implement into a jointer I provide a rearward extension 16′ preferably longer than the extension 16 but of the same general character, the same including a pair of arms 18′ each having a spring catch 20′ cooperating with a stud 19 in a manner similar to that above described. The ribs 17′ of this form of the invention reinforce and stiffen this member. This rearward extension 16′ also is provided with a lip or lips 21a extending forwardly on opposite sides of the base of the handle 12 into cooperation with the rabbet 21′, as shown in Fig. 1. The base of this extension is provided with a socket or notch 16a into which the base of the handle is snugly seated when the extension is shoved forwardly into place. Either of these extensions may be almost instantly attached or detached. The manner of detachment may consist in the holding of the body 10 in one hand and with the other hand spanning the handle or knob and causing two of the fingers of such hand to lift upon the free ends 20a of the catches. Such handle or knob constitutes therefore a fulcrum to assist in such lifting movement, and the pressure between the hand and the ends of the fingers causes sufficient outward or rearward movement of the extension to unlock the catches from the studs. The two parts, then, may be pulled apart directly without resistance. The assembling movement will be readily understood from what has been said above, and requires but a simple shove of the extension directly into its place, the ends 20a of the catches causing the catches to ride automatically over and into engagement with the studs.

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

1. In an implement of the class set forth the combination of a main plane body having a base and upwardly extending side flanges, an extension for said body comprising a base adapted to aline with the body base, said extension also including a pair of arms extending along the body base adjacent the inner surfaces of said flanges, a pair of studs secured to said iianges and extending toward each other in contact with the upper surfaces of said arms to prevent downward tilting of the extension, and means engaging over said studs to prevent longitudinal displacement of the extension.

2. In a plane, the combination with a main body including a base and a pair of upwardly extending lateral flanges, of an extension for either end of said base, said extension comprising a base adapted to aline with the aforesaid base and also including a pair of arms extending along the top of the main base just within the flanges thereof, a pair of studs cooperating directly with the upper surfaces of said arms, a pair of spring catches secured to the arms and adapted to snap automatically over said studs when the extension is shoved into place, and means cooperating with said arms to prevent the upward tilting of the extension.

3. In a plane, the combination of a main body including a base, vertical side flanges extending upwardly from the base, and a pair of studs extending inwardly from the inner faces of said side flanges in alinement with each other and spaced above the upper surface of said base, an extension for the main body including a base adapted to abut against the aforesaid body base, a pair of rigid arms extending from the extension and lying snugly between said studs and the main body base, and means on the arms cooperating with said arms and studs serving to prevent accidental removal of the extension from the base.

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

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, and resident of the town of East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Rabbet-Planes, of which the following is a full, clear, and exact description.

This invention relates to rabbet planes, and the primary object of the invention is to provide a plane having an improved form of guiding extension cooperating with the main part of the stock to form a throat for the bit and adjustably and detachably connected in an improved manner with the stock.

By my improvements, the guiding extension may be firmly clamped in the desired adjustment, when used for ordinary planing, with the throat adjusted to a width suitable to the conditions which obtain in any given case, and when planing in a corner or close to a wall, or the like, the extension may be very readily detached and bodily removed so that the tool will be converted into a bull nose plane. The main part of the stock is provided with a suitable grip portion or palm rest which is equally edective when the tool is used as an ordinary plane or as a bull nose plane.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, in which I have illustrated a preferred embodiment of the invention, Figure 1 is a side elevation of the plane; Fig. 2 is a similar view, taken from the opposite side, the forward extension on the stock being removed; Fig. 3 is a front elevation of the plane; Fig. 4 is a transverse section on line 4–4 of Fig. 1; Fig. 5 is a front view of Fig. 2, with the gages removed; Fig. 6 is a front elevation of the body or stock; Fig. 7 is a vertical longitudinal section through the stock showing the lengthwise adjusting screw for the bit in position therein; Fig. 8 is a horizontal longitudinal section through the stock; Fig. 9 is a bottom view of the stock, with the gages in position; Fig. 10 is a detail view of the adjusting screw; Fig. 11 is a bottom plan view of the bit or plane iron; Fig. 12 shows in plan and in side elevation the clamping lever or cap piece for the bit; and Fig. 13 is a detail view of the pin on which the width gage is mounted.

Referring to the drawings, the stock A is shown as provided with a forwardly directed detachable extension B adapted to form in conjunction with the lower forward edge of the stock a throat a’ (Fig. 1), into which projects a bit or plane iron C, secured in the stock by means of a cap piece or clamping lever D. The bit or plane iron C is adjusted longitudinally by means of an adjusting screw E, and at one side of the stock is a vertically adjustable depth gage F, while at the opposite side a horizontally adjustable width gage G is provided. At the top of the stock A, the same is provided with a suitably formed grip portion or palm rest A’ independent of the extension B.

Referring now to the detailed construction of the parts above mentioned, it will be observed that the forward extension B carried by the stock comprises an arm 15, carrying a foot or guide 16, disposed in advance of the bit, and having its smooth lower portion flush with the bottom face of the stock A. The foot or guide 16 is provided at the top with an upwardly directed gripping projection 17, and it is connected with the arm or bar 15 by means of a downwardly curved portion 18. The arm or bar 15 is adjustable longitudinally of the stock in a longitudinal opening 19, extending through the upper part of the latter, as best shown in Fig. 7, the extension B being clamped in the desired longitudinal adjustment by means of a set screw 20, shown in dotted lines in Figs. 1 and 2, screwed into a counter-bored opening 21 at the upper portion of the stock or body A. By loosening this set screw the extension B may be slid lengthwise of the stock in order to vary as desired the width of the throat a’, and in certain cases, as when planing in a corner, the extension B may be altogether removed.

The lower portion of the body A, beneath the guide opening 19 for the extension B, is provided with a longitudinal opening or chamber 22 (Fig. 7) through which extend the bit C and cap piece D. The bit C rests at its laterally enlarged end c on a beveled foot or extension 23 formed integral with and extending forwardly from the lower front portion of the body A, and at its rear portion it is supported on an adjusting block 24 carried by the adjusting screw E. On top of the bit lies the cap piece or clamping lever D, having at its forward end a nose or enlargement 25 bearing on the front end portion of the bit, and having at its rear end a threaded opening for a clamping screw 20. This screw bears at its lower end against the upper face of the bit, near the rear end of the latter, and as said screw is screwed through the cap piece D (bearing meanwhile on the upper face of the bit) the cap piece will be raised into a position wherein its rear portion abuts a bridge 27 at the rear of the stock (Fig. 7), thereby pressing the nose 25 and clamping screw 26 tightly against the respective ends of the bit. In this manner, the bit may be firmly clamped in position without the use of a pivot screw, or the like, for the clamping lever or cap piece.

The adjusting screw E is provided with a threaded shank 28 engaging an interiorly threaded lug 29 extending upward from the bottom of the stock beneath the bit. Hence, by screwing the screw E in one or the other direction, it will be advanced into or retracted from the stock, carrying with it the block 24. This block is provided at its upper portion with a cross-rib 30 adapted to engage any of a number of transverse grooves 31 on the under face of the bit, so that the bit will partake of the adjusting movement of the block. The latter is guided rectilinearly between the side walls 22x of the stock, it being secured to the screw E by means permitting the relative rotation of the screw and block, but preventing independent longitudinal movements thereof. In the embodiment shown, this means comprises a pin 32 extending transversely across the block and engaging a transverse groove 33 in the body portion of the adjusting screw, as shown in Fig. 7.

The width gage G is preferably formed as a casting of appropriate shape having a finished face 34 directed at right angles to the bottom of the stock and likewise equipped with a sleeve 35 and set screw 36, by means of which the gage is adjustable transversely of the stock on a supporting pin 37 projecting laterally from the stock, as shown in Fig. 3. The depth gage F, on the opposite side of the stock, preferably consists of a plate, having a finished foot portion 33 movable vertically alongside the stock, said plate being clamped in the desired vertical position by means of a set screw 39 engaging a vertical slot 40 in the plate, as shown in Fig. 1. The depth gage F is guided in its vertical movement by means of a tang or projection 41 (Fig. 9) extending from the rear or inner face of the foot 38, and engaging a vertical groove 42 in the side of the stock.

The width and depth gages are preferably reversible, and to this end the opening 43 (Figs. 2 and 7) for the set screw 30 extends completely through the stock, and there is a guide groove 42 on each side of the stock, as shown in Fig. 9. The width gage G is made reversible by extending the opening or socket 44 (Fig. 7) for the pin 37 completely through the body of the stock. In this manner, the pin 37 with the width gage mounted thereon may be fixed to the stock at either side, the depth gage being placed on the opposite side.

In doing work which is readily accessible, the extension B is secured to the stock in the desired adjustment, the width of the throat a’ being optional. The extension not only serves as a guide for the stock, but also as a gripping member to increase the facility with which the tool may be handled. With the extension removed, the tool is converted into a very handy bull nose plane. When working in a corner, the extension may be easily removed by loosening the screw 20, and there will then be nothing to prevent the passage of the forward bit edge completely up to the walls defining the corner, as will be understood. The grip portion or palm rest A’ of the stock, being independent of the removable extension, is equally effective when the plane is used as an ordinary plane, or as a bull nose plane.

Of course, it will be obvious that while the foregoing description is a detailed one, in so far as it concerns the particular embodiment of my invention selected for illustration, the invention is susceptible of many other embodiments within the scope of the appended claims.
