To all whom it may concern:

Be it known that I, GEORGE EGER, a citizen of the United States, and a resident of Plainville, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in a Gauge for Carpenters’ Planes and the like, of which the following is a specification.

The present invention relates to a gauge or fence for use in connection with a combination tool or plane of the type for forming beads, grooves and all kinds of moldings, and the aim of the invention is to provide a gauge of this kind with means for preventing it from being thrown out of set adjustment or alinement relative to the cutter.

In the accompanying drawing:

Fig. 1 is a perspective view of a plane or carpenters plow to which the improved gauge of the present invention is applied.

Fig. 2 is a fragmentary view looking at the front of the plane.

Fig. 3 is a perspective view of my improved gauge or fence.

The plane or plow shown in Fig. 1 is of an old and well known type and, as here shown, the parts are set up or adjusted to form a bead on the corner or edge of a matched timber, shown in dotted lines Fig. 1. The plane in its main parts comprises a main stock a provided with a runner b and a handle c. d is a sliding section adjustably supported on arms e and carrying an adjustable runner f. The letter g denotes the cutter which is adjustably supported on the main stock a.

The gauge or fence to which the present invention particuiarly relates comprises an upper plate 10, a lower piate 11 adjustably connected thereto, and a post 12 extending into a socket or opening in a housing 13. The post is clamped in this socket by means of a thumb screw 14. In the present instance, the lower plate is connected to the upper one by screws 15, and the openings 16 in the upper plate 10 through which these screws extend are elongated so as to allow for adjustment of the lovver plate 11.

The present invention resides in providing for such interengagement between the gauge and one of the runners that the gauge is secureiy held against movement or displacement from its properly adjusted position. In the present instance, this result is accomplished by providing in the upper face of the plate 11 and adjacent its active edge a longitudinally extending groove or slot 17 which is adapted to receive the lower edge of one of the runners, in the present instance runner f.

As previously stated, the parts of the plow are shown as being adjustably set up to form a bead along the edge or corner of a matched timber. The gauge is so set that the edge of the plate 11 engages the side face of the timber so that the gauge acts in the nature of a fence or guide. The inner edge of the plate 11 is immediately beneath the inner point of the cutter g so that the round of the bead will merge without a break or shoulder into the straight face out the timber. In the absence of the groove 17, it has been found that in operation considerable difficulty and trouble have been experienced in that owing to the pressure which must be exerted to keep the edge of the plate 11 flush against the side edge of the timber, the gauge will tend to turn in the housing 13 resulting in faulty work. This difficulty is obviated by providing the groove 17 in the plate, for it will be seen that when the edge of the runner engages in this groove, the plate is securely anchored and is effectively prevented from turning or twisting or being forced out of alinement.

I claim as my invention :–

1. A gauge or fence for use in connection with a plane having a runner, including a vertical post, a plate carried by said post, and means on said plate adapted to cooperate with said runner for anchoring said plate against lateral displacement relative thereto.

2. A gauge or fence for use in connection with a plane having a runner, including a plate having a groove adapted to receive the bottom edge of the runner, and means for connecting said piate to the plane.

3. A. gauge for use in connection with a plane having a runner, including a post, a plate adjustably connected to said first plate and having a longitudinally extending groove adjacent one edge adapted to receive the bottom edge of the runner of the plane.

4. In combination a plane having a runner and a socket; and a gauge including a post secured in said socket, a plate carried by said post, and means on said plate adapted to cooperate with said runner for anchoring said plate against lateral displacement relative thereto.

To all whom it may concern:

Be it known that I, RALPH ALLEN, a citizen of the United States, residing at Shelton, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Carpenters’ Planes; and I do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in —

Figure 1. A view in side elevation showing my improved sheet-metal cutter-cap clamp as applied to a plane which is broken away except one of the upstanding side-flanges of its body.

Fig. 2. A detached plan view of the cutter-cap clamp shown as mounting the clamping-lever.

Fig. 3. A view thereof in central longitudinal section, the lever being shown in elevation.

Fig. 4. A view of the clamp in transverse section on the line 4–4 of Fig. 2.

Fig. 5. A broken plan view of the outer end of the clamp.

Fig. 6. An edge view thereof.

Fig. 7. A detached plan view of the clamping-lever.

Fig. 8. A view thereof in end elevation.

My invention relates to an improvement in carpenters’ planes and more particularly to cutter-cap clamps therefor, the object being to produce a simple, durable, easily operated clamp of greater resiliency and therefore more positive clamping action than the cast-metal clamps now generally employed.

With these ends in view, my invention consists in a one-piece sheet-metal cutter-cap clamp adapted at its rear end to mount a clamping-lever and furnished upon its under face with a spring engaging with the said lever to hold the same in place.

My invention further consists in certain details of construction and combinations of parts as will be hereinafter described and pointed out in the claims.

In carrying out my invention, as herein shown, I produce from a single piece of sheet-metal, such as steel, a cutter-cap clamp 5 having at its forward end a straight gripping-edge 6, and having its side edges turned downward throughout its and having its rear end rounded at the corners and turned downward to form a curved bearing-flange 8. The rear end of the clamp is formed with a longitudinal slot 9 centrally intersecting the curved flange 8 and provided for the reception of the shank 10 of the clamping-lever 11 which is furnished with relatively large trunnions 12 offsetting from opposite faces of its shank and with an operating-cam 13 forming an extension thereof. The respective trunnions 12 aforesaid have bearing upon the inner faces of the curved end-flange 8, at points on opposite sides of the slot 9 as shown in Figs. 2 and 3, and are held against the said flange by means of a spring 14 engaging with the cam 13 of the lever and welded or otherwise fastened to the lower face of the clamp, as at 15, at a point directly to the rear of the reduced rear end of the key-hole slot 16 formed in the clamp for the reception of the screw 17 by means of which the clamp is secured to the inclined cutter-support 18 located between the upstanding flanges or cheeks 19 of the plane body or frame, which may be of any approved construction and is not shown. The cutter 20 rests upon the said support 18. A cutter-cap 21 is placed upon the upper face of the cutter and as so placed is directly interposed between the cutter and my improved cutter-cap clamp. The said spring 14 is accommodated within the chamber 22 formed within the clamp by the downwardly turned side-flanges 7 and the downwardly turned rear end flange 8 thereof.

In the use of my invention, after the cutter has been properly adjusted as to its cutting edge, the clamping-lever is forced downward from its open position, in which it is shown by broken lines in Fig. 3 into its closed position, in which it is shown by full lines in the said figure, as well as in Fig. 1. As the lever is crowded downward into its closed position, its cam 13 acts upon the upper face of the spring 14 and crowds the same down upon the upper face of the cutter with which the cam itself makes no direct contact. As the clamping-lever is crowded into its closed position, as described, the cutter clamp yields throughout its length and to a greater extent than any of the cast-iron clamps heretofore used, the straight gripping-edge 6 of the clamp taking firm hold of the forward end of the cutter, and the spring 14 taking firm hold of the rear end thereof whereby the cutter is positively held against endwise movement.

By providing the clamping-lever with integral trunnions of relatively large diameter and holding the said trunnions in their bearings by means of a spring, I simplify and strengthen the construction over the pivot-pin construction of the prior art, making the plane more durable and also making it easier to operate, as the larger the trunnions, the easier it is to operate the clamping-lever.

I claim:

As a new article of manufacture, a one-piece, sheet-metal, cutter-cap clamp for a carpenter’s plane, the said clamp having its side edges turned downward throughout its length to form side-flanges, and having its rear end turned downward to form a bearing-flange, and provided with a longitudinal slot centrally intersecting the said bearing-flange, whereby the clamp is adapted to mount a clamping-lever, and the said clamp having a lever-retaining spring secured to its inner face and located within the chamber formed by the said downwardly turned side-flanges and downwardly turned rear end bearing-flange.

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

RALPH ALLEN.

To all whom it may concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States of America, residing at New Britain, Connecticut, have invented new and useful Carpenters’ Planes, of which the following is a specification.

The main object of my invention is to provide a simple, rigid construction in which the blade is so supported that it may be readily adjusted to vary the cutting depth and yet so that the blade may be readily removed and replaced in its proper position without changing the adjustment. Another object is to maintain the parallelism of the cutting edge of the cutter when adjusting the depth of cut.

In its preferred form the body of the plane is of metal and provided with a guide frame rigidly secured to the body. The cutter is provided with a detachable clamp block by means of which it is guided in the frame. The adjustment is effected by a screw coacting with the guide frame and the clamp block. A cap member holds the cutter in position.

Figure 1, is a side view of a plane embodying the improvements of my invention.

Fig. 2, is a longitudinal sectional view on the plane of the line 2–2 of Fig. 3 on a larger scale than Fig. 1.

Fig. 3, is a transverse sectional view on the plane of the line 3–3 of Fig. 2.

Fig. 4, is a fragmentary plan view of the parts of the body of the plane embodying my improvements.

Fig. 5, is a detail plan view of the guide frame, detached.

Fig. 6, is a detail view showing the underside of the cutter and the clamp block.

Fig. 7, is a plan view of a cap member.

Fig. 8, is a bottom view of the cap member.

The body 10 of the plane is preferably of metal and in the form shown is provided with a front handle 11 and a rear handle 12. Just in rear of the slot or throat 13, is located an inclined seat 14 between the side flanges 15, 15. Above and to the rear of this seat are seats 16, 16. On these seats 14 and 16 is mounted the guide frame 17, the lower end of which rests on the seat 14 by which it is secured for instance, by means of a screw 18, the head of which is in the recess 19. The sides of this frame 17 are secured to the seats 16, 16 of the body by suitable rivets or screws such as 20, 20, so that the guide frame 17 is rigidly held in place braced between the seat 14 above the sole of the plane and the side flanges 15, 15. Below the guide frame the plane is provided with an inclined seat 21 which forms a continuation of the inclined upper face of the guide frame 17 for supporting the cutter 22.

Attached to the cutter is a block 23 adapted to slide up and down in the opening 24 in the guide frame 17. This block is secured to the cutter by means of an upper piece 25 and the screw 26 which passes through one of the slots such as 27 in the cutter. A thumbscrew 28 which has a threaded engagement with a lug 29 of the guide frame 17 has a grooved tip 30 which engages a forked part 31 on the block 23, so that by rotating the thumbscrew 28 the block 23 and cutter 22 may be adjusted up and down on the inclined seat formed by the guide frame 17 and the part 21 of the body of the plane.

The detachable cap is made up of the two parts 32 and 33 held together by screws such as 34 passing through the slots such as 35. A cross rod 36 connects the two sides of the plane just above the cutter and spaced apart from it sufliciently to permit of introduction of the cap member. The cap member is provided with a shoulder 37 adapted to limit the downward movement of the cap member. The under side of the cap member is recessed at 38 to allow for the clamp piece 25. A thumb screw 39 is adjustable through the cap member for clamping the parts tightly in place.

To remove the cutter it is simply necessary to retract the screw 39, lift out the cap member, whereupon the cutter and the block 23 may be lifted out without affecting the adjustment of the screw 28. To replace the cutter is simply necessary to insert its lower end below the cross rod 36 and drop the forked part 31 of the block 23 over the lower end of the adjusting screw 28, which brings the cutter into exactly the same position which it was before.

It is to be noted that the guide frame which carries the adjusting screw 28 is supported from the sole and side flanges by means of three securing elements 18, 20, 20 thus giving a rigid three point support and insuring against danger of the parts becoming displaced either accidentally or through wear. These seats being relatively small and projecting from the adjacent metal of the body can be readily and accurately finished.

I claim :–

1. A plane comprising a body having a sole and side flanges, a guide frame fitted between said flanges, means passing through said frame at the lower end rigidly securing said frame to said sole, and means passing through said flanges and into said frame for rigidly securing the upper part of said frame to said flanges.

2. A plane comprising a sole and side flanges projecting upwardly from the sole, a guide frame secured near one end to said sole and at another portion to one side flange.

3. In a plane having a sole and side flanges projecting upwardly from said sole, a guide frame secured to said sole and to the side flanges for securing a rigid three point support for the guide frame in the plane body.

4. ln a plane having a sole and side flanges projecting upwardly from said sole, a guide frame between said side flanges, and means passing through said side flanges and into said guide frame for securing the latter in place.

To all whom it may concern:

Be it known that l, EDMUND A. SCHADE, a citizen of the United States of America, residing at New Britain, Connecticut, have invented a new and nuseful Plane-Spur, or which the following is a specification.

My present invention relates to planes and the general objects of the invention are to provide an improved and more efficient spur construction for rabbet, dado and other planes or similar type.

A special object is to rnaintain the setting or adjustment or the spar with respect to the cutting blade.

ln accomplishing the foregoing, I construct the plane stock with teeth projecting into the spur receiving channel and the spur is constructed with teeth to engage and mesh with the teeth on the stock, these teeth being disposed so as to resist the strain exerted on the spur and to thereby rnaintain the spur in its adjusted position. Usually the teeth on the steel are provided hy a hard metal insert seated in the body out the stock.

The accompanying drawing illustrates the invention embodied in a practical and preferred form, but it will be understood that changes and modifications may be made without departing from the true spirit and scope of the invention.

ln the drawing:

Figure 1 is a view in side elevation of a “Stanley Universal” plane having rny invention incorporated therein.

Fig. 2 is a horizontal sectional view taken through the spar construction substantially on the plane of the line 2–2 of Fig. 1.

Fig 3 is a fragmentary view of that portion of the plane stock in which the spur receiving channel and the recess for the anchoring element are formed.

Fig. 4 is a detail perspective view or the so-called anchoring element.

Fig, 5 is a detail perspective view of the spur.

Fig. 6 is a similar view of a modfied form of anchoring element.

The stock or the plane in the case illustrated is formed in front and rear sections 7 and 8 respectively, attached to a back or body member 9, said sections being separated by an angular opening or throat 10 through which the cutter blade 11 projects.

12 designates the spur, located in advance of the cutter and disposed in a channel or seat 13 formed in the side of the front stock section 7. This channel preferably extends substantially at right angles to the cutting plane of the tool, permitting of an up and down adjustment or the spur in the channel for the purpose of setting the spur with respect to the cutter blade, it being understood that the lower cuttiing edge of the spur is usually set slightly below the cutting edge or the blade so as to score the material in advance of the blade.

The spur is locked in its adjusted position in my invention, by providing it on the forward edge thereof with teeth or serrations 14 for engagement with corresponding teeth or serrations 15 on the stock, the spur being held seated in its channel and engaged with the teeth aforesaid by rneans such as a screw 16 extending through a slot 17 in the spur into engagement with a screw seat in the stock at the back or the channel. These interlocking teeth on the stock and spur are disposed in planes substantially parallel to the cutting plane and transversely with respect to the longitudinal adjustment of the spur so as to resist the strain on the spur when the plane is in use.

The teeth on the stock are provicled in the case illustrated by a hard metal disk or washer 18 in the nature of an “insert”, seated in a recess 19 at one side of and opening into the edge portion of the spur receiving channel, this disk having a flattened toothed edge portion projection into the edge part of the channel. The locking or anchor disk 18 may be secured in planes in various ways as by welding or riveting, it being shown in the present instance as held in its seat by a rivet 20. ln Fig. 6 the rivet is shown formed integral with the disk rnember.

This invention rnakes it possible to set the spur to the proper depth with respect to the cutter and to maintain that relation during the subsequent use of the tool and at the same time, it is possible as the cutting edge of the spur wears down, to easily set the spur to at new adjustment or when desirable, to change the position of the spur for cutting in softer or harder woods.

l claim :

1. ln a plane, a stock having a spur receiving channel in one side thereof, a recess in said stock at one side of said channel and opening into the edge of said channel, a hard metal locking device fixed in said recess and having a toothed edge at one side projecting into the side edge of the channel aforesaid, a spur having one edge toothed to coact with the teeth on said locking portion, the width of said spur corresponding to the width of said channel, said spur being adjustably engaged with said locking device by a lateral movement of said spur whereby the degree of projection of said spur below said stock may be controlled, and means for holding said spur against lateral disengagement from said locking device when the latter is in its adjusted operative position.

2. In a plane, a stock having a spur receiving channel in one side thereof, a recess in said stock at one side of said channel and opening into the edge of said channel, a hard metal locking device fixed in said recess and having a toothed edge at one side projecting into the side edge of the channel aforesaid, a spur having one edge toothed to coact with the teeth on said locking portion, the width of said spur corresponding to the width of said channel, said spur being adjustably engaged with said locking device by a lateral movement of said spur whereby the degree of projection of said spur below said stock may be controlled, and means for holding said spur against lateral disengagement from said locking device when the latter is in its adjusted operative position, said holding means comprising a screw passing through a longitudinal slot in said spur and screwing into said stock.

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, 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.

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.

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, 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:

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.

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.

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, 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.

What I claim is :–

l. In a plane, a stock having a longitudinal opening, a bit in said stock and a guiding extension for the plane comprising a guiding foot cooperating with the stock to form a throat for said bit, and also comprising a bar adjustable longitudinally in said opening of the stock; substantially as described.

2.

To all whom it may concern:

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

My invention relates to an improvement in tools, and particularly to so-called hand scrapers such as employed for scraping or smoothing the surfaces of floors or other woodwork.

The invention relates more particularly to the body portion, which is constructed integrally of cast iron and is so designed as to properly hold the cutter in position for service.

It is the purpose of my invention to provide certain improvements in the construction of the body or frame, and by said improvements to overcome the errors and weaknesses existing in tools of this general description as heretofore constructed; that is to say, by the present design the user may grasp the tool in such a way as to apply his power with the greatest efficiency; the construction also being such that the handle portions are connected to the central body portion by a much stronger connection than that heretofore employed in an iron scraper body or frame.

In the accompanying is a perspective view scraper. Fig. 2 is a front elevation, partly in section. Fig. 3 is a rear elevation.

1 is the sole portion or base.

2 is an upwardly projecting wall arranged longitudinally of the base and between the front and rear edges.

3 is a slot which extends transversely through the base about midway betvveen the front and rear edges and just to the rear of the wall 2. The cutter, later described, projects through this slot, the slot being of an appropriate length for the cutter. The sole 1 and the wall 2 constitute the central portion of the scraper body or frame.

4–4 are handles which are arranged at each end of the central or main portion, the handles being cast integrally therewith, each handle being united to the central body portion in the unique manner now described. A description of the means for drawings, Figure 1 of my improved connecting one handle with the main body will suihce for both, as the means of connection corresponds in each instance.

5 is a curved flange connecting the inner end of the handle 4 with the side edge of the sole portion 1 forward of the wall 2.

6 is a curved flange connecting the inner end of the handle with the side edge of the sole portion 1 back of the wall 2.

7 is an upwardly curved flange connecting the handle with the side edge of the wall 2. These flanges operate in effect as longitudinally arranged strengthening ribs which extend far enough into the handle portion to constitute a very powerful connection. Each handle proper is in effect corrugated so as to get the maximum strength with the least weight, the corrugation being on the under side and appearing in Fig. 2 at the right hand side.

8 is a cutter blade.

9 is a clamping plate connected in any suitable manner, as by thumb screws 10–10 to the rear of the wall 2. This clamping plate 9 serves to hold the blade 8 firmly against the back of the wall 2, with the edge thereof projecting therethrough to the desired extent.

11 is a thumb screw which is located about midway in the wall 2 on the opposite side from the thumb screws 10–10. The inner end of this thumb screw 11 is arranged to engage the blade 8 to bend it slightly baclr at the center, as it is found that it operates more easily when thus buckled or bent.

In operation, the operator grasps the handles 4–4 with the fingers, while his thumbs project down into the spaces at the meeting angles of the front part of the sole, the front part of the wall and that part of the handle between the flanges 7 and 5. The ball of each thumb rests well down on the upper surface of the sole 1 very close to the work, so that the pressure of the thumbs will be applied to the greatest advantage, the position of the thumbs being such that a minimum of exertion is required of the operator, each thumb standing in a substantially straight position rather than being bent. Heretofore in the construction of iron scraper bodies it has been customary to provide a substantially vertical wall at each end of the sole 1, forming a box-like structure, thus requiring the operator to bend each thumb in order to get any thumb pressure directly on the sole. This is not only tiresome, but it is obvious that the operator’s full power cannot be applied when the pressure is exerted through the end of the thumb. It is apparent, of course that each handle curves upwardly so as to afford clearance for the fingers. In this, however, there is no novelty, as it is common in all scrapers of this general class.

In the old box-like type of construction above referred to, the connection between the handles and the main central body is comparatively weak, with the result that if the tool is accidentally dropped, breakage frequently occurs where one or the other handle is united to the main body. By the present invention I not only avoid the box-like structure due to the old end wall formation, but I also connect each handle with the main central body so that a maximum of strength is afforded, very much minimizing the danger of breakage. I have referred to that part of the main body which faces the operator as the front part. It will be understood that in operating the scraper the cutting stroke is performed ordinarily by pushing the tool away from the operator while pressing it firmly against the surface which is to be smoothed.

What I claim is:

1. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of longitudinally arranged rib-like flanges extending from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles.

2. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of longitudinally arranged rib-like flanges extending from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles, each handle being connected to the cutter opening by not less than three of said rib-like flanges, one of said flanges extending forwardly to meet the side edge of the sole forward of the wall, another extending rearwardly to meet the edge of the sole to the rear of the wall, another extending upwardly to meet the edge of said wall.

3. A scraper body including a main central portion comprising a sole having a slot therein constituting a cutter opening, a wall projecting upwardly at the forward edge of said cutter opening, two handles arranged at opposite ends of the main central portion and integrally connected therewith, said connection including a series of rib-like flanges extending longitudinally from the edges of the sole portion and said wall and merging by gentle curves into and forming part of the handles, with means for holding a cutter against the rear surface of said wall.

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 new and useful lmprovements in Planes, of which the following is a specification when taken in connection with the accompanying drawing.

This invention relates to planes, and the primary object of the invention is to provide iinproved means for mounting a single adjusting element, such as an adjusting screw, which is capable of adjusting the bit laterally as well as longitudinally. The lateral adjusting rnevernent, which is provided for by a special mounting of the adjusting screw or other element, enables the plane bit to be oscillated to a certain extent relative to the longitudinal axis of the plane so that the cutting edge of the bit may be brought into exact parallelism with the throat in the stock or frame. At the same time, the adjusting screw, or its equivalent, retains its usual function of moving the plane bit longitudinally, i. e., into and out of the throat.

With the foregoing and other objects in view, the invention consists in the novel features and coinbinations of parts to be hereinafter described and claimed.

In the accompanying drawing, illustrating a preferred form of the invention, Figure 1 is a side elevation of the plane; Fig. 2 is a top plan view of the same with the cap removed; Fig. 3 is a fraginentary plan view of the rear portion of the plane, the cap and bit being omitted.; Fig. 4 is a detail plan view of the swivel socket or standard for the adjusting screw; Fig. 5 is a vertical transverse section through the stock, taken immediately in front of the socket for the adjusting screw; and F ig. 6 is a detail view of the adjusting screw and its pivot or swivel mernber.

Referring to the drawing, 10 indicates the body or stock of the plane, which may be of any preferred form.

11 is the usual throat in the bottom of the stock into which extends a bit 12 of customary form, surmounted by a cap 13 of ordinary construction. The bit 12 is secured in the stock by means of a screw (not shown) screwed into an internally threaded socket 14 rising from the bottom of the stock, said screw securing the cap 13 in place against the bit in any well known manner, and the longitudinal adjustment of the bit being provided for by a longitudinal slot 15, through which the aforesaid screw freely passes. When the bit and cap have been properly adjusted with respect to the screw projecting out of the socket 14, the parts are tightly clamped in place by means of a cam device 10 of any ordinary construction associated with the cap, as shown in Fig. 1.

The parts so far described are well known, and form no part of the present invention, which is chiefly concerned with the provision of a single adjusting device for giving the bit 12 lateral and longitudinal adjusting movements. This adjusting device comprises an adjusting screw 17 having its threaded shank 18 screwed into, and preferably through, a pivot or swivel member 19 which is so mounted on the bed of the stock as to enable it to be oscillated relative to the longitudinal axis of the plane. In the form shown, the swivel member 19 is of cylindrical shape and is fitled within a socket 20 rising from and preferably integral with the bed of the plane. This socket is provided interiorly with a forwardly and rearwardly inclined seat 21 in which the cylinder 19 is seated, and the cylinder 19 is retained in said seat by means of side walls 22 rising froin the socket 20 and conforming to the side walls of the cylinder 19, as shown in Fig. 3. The walls 22 are separated from each other at the front and rear of the socket by spaces 23 and 24, respectively, which enable the set screw 17 to be oscillated laterally to a certain extent, altliough the walls 22 form stops which limit the movement of the adjusting screw when it is swung toward the respective sides of the plane stock.

The screw 17 is manipulated by a milled head 25, and it is connected with the plane bit 12 by means of a neck portion 26 engaged by a bifurcated lug 27 swiveled in the rear portion of the bit, by means of a swivel pin 27a, as shown in Fig. 2.

It will be apparent that if the adjusting screw 17 is swung into line with the longitudinal axis of the plane, the screwing of said screw into and out of the member 19 will advance the cutting edge of the bit into and out of the throat 11 by a movement of the bit along the longitudinal axis of the plane. This adjustment may of course be effected when the cap 13 is in its clamping position. When the cutting edge of the bit is so ground that it does not lie at a right angle to the longitudinal axis of the bit, said cutting edge may be brought into parallelism with the throat 11 by swinging the adjusting screw to one side or the other of the plane, as shown in Fig. 2. This adjustment is also permitted while the cap is in its clamping position. By pushing the head 25 in the desired direction the screw 17 and its swivel member or pivot 19 will be moved angularly about the forwardly inclined axis of the socket 20, thereby shifting the bit into the desired position. The adjusting screw and its swivel member or pivot may be easily removed from the plane by simply lifting said swivel member or pivot out of the socket 20.

When the bit or cutter is swung laterally it usually turns about the point of contact of one of its forward corners with one of the side walls of the stock. The adjusting screw 17, on the other hand, turns about another point. For this reason the swiveling of the lug 27 on the bit is a valuable feature, inasmuch as the lug is free to follow the various movements of the screw without any binding effect.

The construction described has the great advantage that by a suitable manipulation of the head of the adjusting screw the cutting edge of the bit may be given a compound adjustment which will locate it almost instantaneously in the desired position in the throat of the plane.

One of the important features of the invention resides in the fact that while the standard 20 rises directly from the bed or bottom of the stock and thereby holds the adjusting screw very firmly in the proper position beneath the bit, said screw is mounted to oscillate in a plane parallel to the bit rather than in a plane parallel to the bottom or sole of the plane. This provides for a direct connection of the bit with the adjusting screw without the use of a number of special parts interposed between these instrumentalities. lt will be noted, moreover, that the bit is directly supported at its rear portion by the standard walls importance in place with the other marked inclined top surfaces of the 22, which is of considerable securing the bit firmly in aid of very few parts. An advantage arises from the fact that the adjusting screw can be freely lifted out of the swivel standard, so that after the cap has been removed the bit and adjusting screw can be lifted instantly out of the assembled position.

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

1. ln a plane, a stock, a bit, a standard rising from the bed of the stock and directly engaging the under surface of the bit to support the same, an adjusting screw, and a carrying member for said adjusting screw swiveled in the upper end of said standard, between the standard and bit, to swing in a plane parallel to the bit; substantially as described.

2. ln a plane, a stock, a bit, a standard rising from the bed of the stock, and having an inclined upper end directly engaging the under surface of the bit, an adjusting screw, means permanently carried by the bit to engage said adjusting screw, and a carrying or pivot member for said adjusting screw set in the inclined upper portion of said standard directly beneath the bit, and arranged to oscillate in a plane parallel to the bit; substantially as described.

3. ln a plane, a stock having a socketed standard rising from the base thereof, a pivot member loosely seated in the socket of said standard to oscillate therein and freely removable from said standard, and an adjusting screw threaded through said pivot member; substantially as described.

4. In a plane, a stock having a socket portion rising from the base thereof, said portion presenting a socket having its axis inclined in a forward and rearward direction, and being provided with side walls spaced apart at the front and rear, a pivot member set in said socket, and an adjusting screw threaded through said pivot member and having an oscillatory movement limited by the side walls of the socket; substantially as described.

5. ln a plane, the combination of a stock, a bit supported therein for laterally oscillating movement, an adjusting screw for the bit swiveled laterally on the stock, said screw having a reduced neck portion, a lug depending from the rear portion of the bit and straddling said reduced neck portion of the adjusting screw, and a swiveled connection between said lug and said bit to permit the bit to turn eccentrically of the adjusting screw as said screw is moved laterally; sub-
stantially as described.

6. In a plane, a stock, a bit therein, an adjusting screw for the bit, a carrying member into which said screw is threaded, and a socket for said member on the bed of the stock comprising spaced side walls which limit the swinging movement of said screw; substantially as described.

7. ln a plane, a stock, a bit therein, an adjusting screw for the bit, an approximately cylindrical swivel member into which said screw is threaded, and a socket on the bed of the stock conforming to said cylindrical swivel member and mounting it to turn in a plane parallel to the bit; substantially as described.

8. In a plane, a stock, a bit therein, an adjusting screw for the bit, an approximately cylindrical carrying member into which said screw is threaded, a socket on the bed of the stock conforming to said cylindrical carrying member and mounting it directly beneath the under surface of the bit, and means to limit the lateral movement of said screw; substantially as described.

In witness whereof, I have hereunto set my hand on the 23rd day of January, 1912.

To all whom it may concern:

Be it known that we, CHRISTIAN BODMER and JAMES M. BURDICK, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, respectively, have invented certain new and useful Improvements in Plane-Caps, of which the following is a full, clear, and exact description.

This invention relates to improvements in the construction of planes and is more particularly concerned with cap pieces for the cutters or plane irons thereof of the type shown in our prior U. S. Patent No. 1,053,274, dated February 18, 1913.

The present invention aims to provide a cap piece of the general type shown in this prior patent, but embodying specific structural improvements.

A preferable embodiment of our improved form of cap piece is illustrated in the accompanying drawings in which —

Figure 1 is a longitudinal sectional view through a standard type of plane equipped with the cap piece of the present invention. Fig. 2 shows a longitudinal section through the palm rest and base sections, detached. Fig. 3 is a view in elevation of the cam lever. Fig. 4 is a bottom plan view of the base plate. Fig. 5 shows a side elevation, partly in section, of a modified form of cap piece, said cap piece being removed from the plane and the parts being shown in cutter clamping position. Fig. 6 is a longitudinal section of the palm rest section thereof, detached. Fig. 7 shows the base plate section thereof in longitudinal section and bottom plan. Fig. 8 is a detail of the clamping lever and its roller.

Referring to the drawings: numeral 1 designates the body of a plane of the channel type provided with side walls 2 and a detachable shoe 3 at the forward end thereof, the usual throat 1a being formed adjacent the forward end of the plane.

4 is a frog or seat for the forward end of the plane iron or cutter.

5 designates an interiorly threaded boss projecting upwardly from the plane body and carrying what is commonly termed a “cap screw” 6, provided with the usual headed end 6a. An adjusting lever 10 has its forward end seated over the boss 5 and is provided with an adjusting head 10a A second adjusting device is shown in the form of a lever member 8 pivotally mounted on the plane body and engaged at its rear end by an adjusting nut 9.

7 designates a plane iron or cutter provided with the usual longitudinal slot therein, this cutter being seated on the body of the plane with its forward end resting on the seat 4, and its cutting edge projecting into the throat 1a, the intermediate portions of the cutter resting respectively over the boss 5 and the end of the adjusting lever 8. The adjusting head 10a of lever 10 seats within the slot of the cutter. It will be, of course, understood that this slot is such as to enable the cutter to be seated on the plane body as described with the cap screw 6 projecting through the slot therein. We lay no claim to the specific structure of such a plane, inasmuch as it merely represents a standard type of plane with which the cap piece forming the subject matter of the present invention may be utilized. This cap piece embodies a base plate 11 having a curved forward end shaped to engage the forward end of the cutter resting on the seat 4, this base rearwardly of its curved end being provided with side flanges 12 preferably curving inwardly as seen in Fig. 4. Centrally of the base and intermediate the side flanges is a key-hole slot 13. Intermediate this lrey-hole slot and its rear end, this base plate is provided with a second and elongated slot 14 having lateral enlargements 14a intermediate its ends. Cooperating with this base member is a hollow convex cap 15 forming a palm rest, this palm rest section being hinged or pivoted to the base by means of a pivot pin 16 which may extend transversely of the base and through the side walls 12 at their forward ends. This palm rest section 15 is of sufficient width to inclose between its sides the rearwardly extending flanged portion of the base member 11, and in line with the narrow portion of the key-hole slot 13 thereof, is provided with an aperture 17 forming therewith an annular locking shoulder. 18 designates a bracket extending inwardly from the inner face of the palm rest section at a point in line with the forward end of the elongated slot 14 in the base member. To this bracket is pivotally secured the forward end of a clamping cam lever 19 which is provided with a cam slot 20 therein adjacent its rear or lower end, this cam slot having at its upper or forward end an angular offset forming a locking shoulder 21. This cam lever extends through the elongated slot 14 in the base and its end slot 20 guides upon a roller 22 journaled in the flanges 12 of the base and positioned within the lateral enlargement 14a of the elongated slot.

With the foregoing description in mind, it will be evident that in use, the plane cutter having been seated on the plane body in the desired position, the base 11 is brought to bring the enlarged end of its key-hole slot over the head 6a of the cap screw and is then moved upwardly to bring the head of the cap screw above the narrow portion of its key-hole slot, the palm rest section of the cap piece during this operation being held in the raised position indicated in dotted lines in Fig. 1. When this has been done, the palm rest section is then swung downwardly toward the base member 11, this movement causing the cam lever 19 to swing downwardly therewith to bring its lower edge into frictional clamping engagement with the upper face of the cutter (or of a clamping plate superposed thereon). This clamping action is effected through the cooperation of the cam slot 20 with the roller 22. When the palm rest section has been moved downwardly relative to the base sufficiently far to clamp the cutter on its seat, the roller 22 will have reached the upper or angularly offset end of the slot and will abut against the locking shoulder 21 formed thereby with the main body of the cam slot. At the same time, the aperture 17 at the forward end of the palm rest section will have been brought about the head ea of the cap screw. The edges of the palm rest adjacent said aperture being located at either side of said cap screw will prevent longitudinal movement of the entire cap piece relative to the cap screw and plane body with which it is rigid. The clamping engagement of the cam lever with the cutter is such that it holds the latter tightly on its seat, and under ordinary service conditions its position will be unchanged. The cutter, however, is always capable of being adjusted by the adjusting means provided without loosening the cap.

The frictional engagement of the cam lever with the cutter is maintained by reason of the engagement of the roller 22 with the locking shoulder 21 of the cam slot which shoulder serves to lock the cap piece in cutter clamping position and against accidental displacement. When it is necessary to detach the entire piece, however, a sharp pull on the palm rest section will move the shoulder 21 beyond the roller 22 and will permit the palm rest section to be raised, this action withdrawing the apertured forward end of the palm rest section from about the head of the cap screw so that the base may be moved relative to the cap screw to bring its head in alinement with the enlarged end of its key-hole slot 13, whereupon the base plate 11 and the attached palm rest section may be lifted from the plane body and from engagement with the cap screw.

In Figs 5 to 8, we have illustrated a modified form of cap piece embodying the same general idea. In Figs. 5 and 7, 11a designates the forward curved end of the base member, and 12a the side flanges thereof, the rear end of the base being preferably raised somewhat as at 13a and having formed in the forward end of its flange portion a key-hole slot 13b, and adjacent its rear end and rearwardly of said key-hole slot, an elongated slot 15a. A hollow convex palm rest section 16a is pivoted at its forward end to the flanges 12a and is provided at its forward end and at a point above the restricted end of the key-hole slot 15a with an aperture 17a providing the palm rest at that point with an annular locking shoulder. From the under face of the palm rest section adjacent the forward end of the slot 15a a bracket 18a extends inwardly. Complemental links 19a are pivoted to this bracket and extend through the elongated slot 15a in the base member. The flanges 12a adjacent their rear ends are provided with complemental alined cam slots 20a, these slots at their rear ends being provided with annular extensions or offsets forming locking shoulders 21a. The links 19a at their rear ends carry a clamping roller 22a whose spindle 23a guides in the cam slots 20a, the width of these slots corresponding substantially to the diameter of the spindle. The operation of this form is substantially the same as that of the first form of the cap piece described. The base member is seated on the cap screw and over the cutter in the same manner and the palm rest section is moved downwardly relative thereto, this movement moving the links 19a and their roller 22a downwardly, the cam slots 20a guiding the roller 22a into frictional clamping engagement with the upper face of the cutter and the spindles 23a of this roller seating at the end of its clamping roller in the offset extensions of these cam slots and engaging the locking shoulders to detachably lock the cap 6 in clamping frictional engagement with the cutter.

While we have herein illustrated preferable embodiments of the invention, it will, of course, be evident that the same is susceptible of modification in structure and relative arrangement of parts, within the spirit of the invention and the scope of the appended claims.

What we claim, therefore, and desire to secure by Letters Patent is :–

1. A cap piece for use in connection with plane bodies provided with abutment studs projecting upwardly from the cutter seats thereon, comprising a base adapted to be seated over a cutter, a palm rest pivotally secured to said base, a clamping lever carried by one of said parts, arranged upon movement of said palm rest relative to said base, to cooperate with means carried by the other of said parts to thereby clamp a cutter on its seat, said clamping means including a cam on one of said cooperating parts having a locking shoulder thereon, and a member carried by the other of said parts engaging said cam and arranged to engage said shoulder to lock said clamping lever in cutter clamping position.

To all whom it may concern:

Be it known that I, ALBERT F. SCHADE, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful lmprovements in Jointer~Gage Attachments for Planes, of which the following is a full, clear, and exact description.

This invention relates to planes, and particularly to an improved form of jointer gage attachment therefor, providing means for securely clamping the attachment to the plane body, which means will permit the use of the attachment in connection with various standard makes and sizes of plane bodies irrespective of thickness of the side walls of said bodies or the angle of junction of said side walls with the base of the plane body. Furthermore the clamping means are such that they may be readily moved to either clamping or unclamping position and, when once moved to clamping position, are firmly held in such position. These and other advantages will be more clearly seen from the taken in detailed specification following, connection with the accompanying drawings forming part thereof and showing a preferable embodiment of the invention.

In these drawings, Figure 1 is a view in side elevation of a jack plane having my improved form of jointer gage attached thereto. Fig. 2 is a rear end view of the parts shown in Fig. 1. Fig. 3 is a fragmentary view in elevation, of the plane body with the gage attached, on an enlarged scale. Fig. 4 is a fragmentary longitudinal section through the plane body looking outward toward the gage attached thereto. Fig. 5 is a vertical section on an enlarged scale taken on the line 5–5 of Fig. 1. Fig. 6 is a detailed view in elevation of one of the clamping plates.

Referring to the drawings by numerals, 1 indicates the base and 2 the side walls of a metal plane body of standard channel section type, the side walls 2 being beveled upwardly toward the center from their ends, as is usual in this type of plane. The device of the present invention is adapted for application to a plane body of this type and provides a gage whereby the angle of out may be varied to suit different requirements, such as in joining two parts at an angle. It consists in the present instance of a base member or bar 3 adapted to extend longitudinally of the outer edge of the plane body beneath its lower edge, this bar being provided with inwardly extending flanges 11 adapted to seat against the under face of the base 1 of the plane body. This bar is provided with a plurality of upwardly extending standards 5, these standards being preferably located at or adjacent the ends of the bar and each being provided with a lateral and preferably integral offset 6 having its lower edge positioned above the maximum point to which the forward and rear ends of the side walls of a plane of standard make extend. These offsets are provided with vertically extending threaded bores therein through which are inserted clamping screws 7, the lower ends of which are adapted to be brought into contact with the upper edge of the side wall of the plane body, drawing the flanges 4 of the base bar firmly against the under face of the base 1 of the plane body. The standards 5 of the base member are provided with clamping plates 8 having end flanges 9, these clamping plates being provided with threaded bores therein. A clamping screw 10 extends through an alined bore formed in each standard 5 and engages the threaded bore of its clamping plate 8, this screw preferably having its outer end winged, as at 11, to provide means for manual operation. The clamping screws 10 are of such length that the clamping plates 8 carried thereby will extend inwardly of the plane body beyond the inner face of a side wall 2 of maximum thickness so that by manipulating the clamping screws 10, these plates may be moved outwardly to bring their lower flanges into clamping engagement with the inner face of the side walls 2 of the plane body, their upper flanges resting against the inner face of a standard 5, and the inner faces of the standards engaging the outer face of the side wall. lt will be evident that the base member 3 may be attached to a plane body and held against either lateral or longitudinal movement relatively thereto by means of its plurality of clamping plates 8 which engage the inner face of a side wall of the plane body, and by means of its plurality of clamping screws 7 which engage the upper edge of said side wall. In this connection, it will be noted that once these clamping screws 7 have been moved to bring the flanged portions 4 of the bar against the under face of the base 1 of the plane body, they firmly hold the base member against movement longitudinally of the body by reason of the upwardly extending beveled edges of the side wall 2 with which they are engaged. I find that in practice it is necessary to provide at least two lateral operating clamping members in order to hold the device securely to the plane body and prevent loosening thereof. Furthermore, the provision of the clamping screws adjacent each end of the base member and of the plane body prevent endwise movement of the base member relative to the body by reason of the incline of the side walls of said body.

Extending laterally and outwardly from the base member 3 and preferably integral therewith is an arm 12 having its outer end apertured to receive a bolt 13, upon the outer end of which is mounted a wing nut 14. The base member or bar 3, adjacent its ends, is provided with bifurcations 15 forming bearings between which an angle plate 16 is hinged by means of knuckles 17. A link 18 is provided, pivotally connected at 19 to the angle plate 16 adjacent its lower edge, and having a curved slot 20 formed therein, this slot being formed on an arc with the hinge point of the knuckle 17 as the center. The bolt 13 extends through this curved slot as well as through the aperture in the arm 12, the link 18 being positioned against the face of the arm 12 and the wing nut 14 being mounted over the end of the bolt 18 so that it can be screwed up to engage the face of the link 18 and clamp the same firmly against the arm 12. By this means the angle of the plate 16 relative to the base 1 of the plane body may be varied at will, and the angle of the planing action thereby varied to suit varying conditions. In order to assist the operator in holding the forward end of the plane against the work when my improved attachment is secured to the plane body, I provide a handle member 21 extending outwardly from the forward standard 5 of the attachment so that by grasping the handle proper of the plane body and this auxiliary handle 21, the angle plate 16 may be held firmly against the work.

While I have herein described a preferable embodiment of my invention, it should be understood that the same may be modified within the spirit of the invention and the scope of the appended claims.

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

1. In a device of the character described, in combination with a plane body of channel section, a base member adapted to engage the base and adjacent side wall of said plane body, a plurality of spaced clamping plates connected with said base member and adapted to be moved laterally into clamping engagement with the inner face of said side wall, a clamping member carried by said base member and adapted to be moved vertically into clamping engagement with the top edge of said side wall, an angle plate pivotally carried by said base member adjacent its lower edge, and means for adjusting said angle plate relative to its base member.

2. In a device of the character described, in combination with a plane body of channel section, a base bar provided with a plurality of spaced upwardly extending standards adapted to engage the side wall of said plane body and with a flange adapted to engage the base of said plane body, clamping plates connected to said standards and adapted to be moved laterally into clamping engagement with the inner face of said side wall, a plurality of spaced clamping members carried by said base bar adapted to be moved vertically into clamping engagement with the top edge of said side wall, an angle plate hinged at its edge to said base bar adjacent its lower edge, and means for adjusting the angle of said plate relative to said base bar and plane body.

3. In a device of the character described, in combination with a plane body of channel section having the top edges of a side wall inclining upwardly from the ends toward the center, a base member adapted to engage said side wall and the base of said plane body and extending longitudinally thereof, clamping means connected to said member adapted to be moved laterally into clamping engagement with the inner face of said side wall, a clamping screw carried by said base member adjacent the opposite ends thereof and adapted to be moved vertically into clamping engagement with the upwardly inclining top edges of said side wall, an angle plate pivotally connected adjacent its upper edge to said base member adjacent its lower edge, and means for adjusting the angle of said plate relative to said base bar and plane body.

4. In a device of the character described, in combination with a plane body of channel section, a base bar extending longitudinally of the plane body and provided with spaced upwardly extending standards adjacent each end thereof adapted to engage the side wall of said plane body and with a flange adapted to engage the base of said plane body, a clamping plate connected to each of said standards and adapted to be moved laterally into clamping engagement with the inner face of said side wall, offsets from said standards, clamping screws threaded through said offsets and adapted to be moved vertically into clamping engagement with the top edge of said side wall, an arm extending outwardly from said base bar, an angle plate pivoted adjacent its upper edge to said base bar adjacent its lower edge, and connections between said plate and arm whereby the angle of said plate relative to said base bar and plane body may be adjusted.

To all whom it may concern:

Be it known that we, JAMES M. BURDICK and HUBERT P. RICHARDS, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to an improvement in the construction of planes, and is more particularly concerned with the construction of a detachable cap piece for the cutter or “plane iron”. In such cap pieces, it has hitherto been the practice to provide a detachable cap piece provided with means for engaging with the cutter and clamping it in position upon its seat upon the plane body.

The present invention contemplates forming such a cap piece as a base portion adapted to be seated on the plane body and to engage and fulcrum on an abutment carried thereby, and a palm rest connected with and movable relatively to said base portion, the latter being provided with a clamping lever and the palm rest being operatively connected therewith so that when moved relative to the base, it will move said clamping lever into and out of engagement with the plane cutter. Furthermore the cap is so constructed that when the palm rest is moved to clamp the cutter on its seat, the base is locked against movement relative to its fulcruin and the clamping lever and its connections are themselves automatically locked against accidental retraction from such clamping position.

In the drawings, which illustrate a preferable embodiment of the present invention; Figure 1 is a longitudinal sectional view through a standard type of plane equipped with a detachable cap constructed in accordance with the present invention. Fig. 2 is a bottom plan view of the cap detached from the plane body.

Referring to the drawings by numerals: 1 designates the body of a plane provided with side walls or flanges 2 and a detachable shoe 3 at the forward end thereof, a throat le being formed at the forward end of the plane and in the rear of the detachable shoe portion thereof. 4 designates a frog or seat for the forward end of the “plane iron” or cutter, and 5 an interiorly threaded boss projecting upwardly from the plane body and carrying what is commonly termed a “cap screw” 6 provided with the usual headed end 6a. An adjusting lever 10 has its forward end seated over the boss 5 and the plane is provided with a second adjusting device comprising a lever member 8 pivotally mounted at its forward end in the plane body and engaged at its rear end by an adjusting nut 9. A “plane iron” or cutter 7 is seated on the body of the plane with its forward end resting upon the frog or seat 4 and its cutting edge projecting into the throat 1a, the intermediate portions of the cutter resting respectively over the forward ends of the adjusting lever 10 and of the second adjusting lever 8. This cutter is provided with the usual longitudinal slot through which the cap screw 6 projects and through and within which the adjusting head 10a extends, and with a plurality of corrugations 7b formed in its under face which are engaged by the forward end of the adjusting lever 8 to effect vertical adjustment of the cutting edge of the cutter. The lever 10, through its adjusting head 10a, effects angular adjustment of said cutting edge within the throat 1a, while the adjusting lever 8 is adapted to tilt the cutter to move its cutting edge vertically in said throat and thereby adjust the depth of cut.

The parts so far described are merely those of a standard type of plane which has been selected for the illustrative application of the detachable cap embodying our invention.

The cap constituting the present invention embodies a base plate 11 having its forward end 11a curved downwardly to engage with the forward end of the cutter 7. At its rear end the base plate 11 is provided with trunnions 12 formed by rolling back the rear edge of the base plate. A narrow slot 13 extends forwardly and centrally from the rear end of the base plate and is provided with an enlargement 14 forming a continuation thereof and with a second enlargement 15 forming the terminal of the slot. The under face of the base plate at either side of the terminal enlargement 15 is provided with downwardly extending ears 16. A hollow convex body 17 forming a palm rest has its forward end narrowed and provided with spaced lugs 18 fitting through the terminal slot 15 in the base plate and lying in transverse alinement with the ears 16. A link member 19 has its forward end formed as a U shaped bracket 19a and has its rearwardly extending end slotted to form spaced links 19b. The forward bracket end of this link member is seated between the spaced lugs 18 of the palm rest and a pivoted pin 20 is inserted through alining apertures formed in the ear 16, lugs 18 and bracket end 19a of the link member, thereby pivotally connecting the palm rest to the base plate and journaling the link member 19 on the pin 20. A lever member 21 forming in effect a bell crank lever is pivotally mounted at the apex of its angle between the trunnions 12 by means of a pivot pin 22, the lever extending down through the slots 13, 14, and having its lower end formed as a cam 23. The forward end of this bell crank lever is formed with a slot 24 and is positioned between the spaced links 19b at the rear end of link member 19, a pin 25 connecting these links and extending through the slot 24 in the forward end of the lever. The slotted enlargement 14 is of sufficient width to admit the movement of the link ends 19b therethrough and the lugs and the terminal enlargement 15 is of sufficient width to permit the insertion therethrough of the lugs 18 depending from the forward end of the palm rest and positioned between the ears 19 of the base plate 11. It will be evident from the foregoing that when the palm rest 17 is moved on its pivot pin 20 relative to the base plate, it will through the connecting link member 19, move the bell crank lever to bring its cam end into and out of engagement with the cutter 7. The connection of link member 19 with the slotted end of the bell crank lever 21 is such that when the palm rest is moved downwardly to bring the cam end of the lever into cutter clamping position, the link and lever automatically lock themselves against accidental retracting movement. This is caused by the fact that the pin 25 connecting the link member 19 with the bell crank lever 21 is brought below the “dead center” between pivot points 20 and 22 when the palm rest is so moved (see Fig. 1).

The base plate 11 adjacent its forward end and centrally thereof is provided a key-hole slot 26, the enlarged portion of the slot being at the forward end of the base plate and the end of the narrowed portion of the slot rearwardly of the base plate being beveled to conform to the beveling of the head 6a of the cap screw.

With the foregoing construction of the parts in mind the operation and use of the cap is as follows: Assuming that the cutter 7 is seated on the plane body as shown in Fig. 1, with the cap screw 6 extending through the slot 7a therein and the cutter being properly positioned relative to the adjusting devices, the cap with the palm rest raised, is seated thereover by bringing the enlarged end of the key-hole slot 20 over the head of cap screw 6 and then moving the base plate 11 downwardly on the cutter to bring the narrowed portion of the key-hole slot around the head 6a of the cap screw and with the beveled edges of the base plate at the end of said slot abutting against the head 6a. The palm rest 17 may now be moved downwardly this movement causing the base plate to press against and fulcrum on the abutment formed by the headed cap screw 6 and causing the pin 25 carried by the link member 19 to move in the slot 24 of lever 21 and move the cam 23 at the lower end of said lever into frictional clamping engagement with the upper face of the cutter 7 (or when a clamping plate is employed in conjunction with the cutter, into frictional clamping engagement with said plate). The pin 25 will then be beyond the dead center and the link member and clamping lever will therefore be automatically locked against accidental retracting movement. This will also hold the beveled edges of the base plate 11 at the end of the key-hole slot locked against the head 6a of the cap screw abutment thereby affording additional means for preventing movement of the base plate and cap relative to the plane body during service and retaining the cap and its parts in clamping position on the cutter. The degree of frictional clamping engagement of the cam with the cutter is such that the cutter is held fixed on its seat during ordinary service but may be adjusted relative to the cap piece and plane body at any time and by any suitable means without loosening the cap piece or moving it relative to the plane body.

To detach the cap from the plane, it is only necessary to move the palm rest upwardly from the base plate, the application of sufficient force causing the pin 25 to move in slot 24 of the lever and by frictional contact therewith move said lever and its cam end from frictional clamping engagement with the cutter 7. When this has been accomplished, the pressure against the fulcrum head 6a of the cap screw is removed and the base plate 11 may now be moved upwardly on the cutter 7 to bring the enlarged end of its key-hole slot in line with the head of the cam screw, whereupon the cap may be readily detached from the cutter and plane body.

We are aware that the broad combination of elements recited herein is described and claimed in the co-pending application of Christian Bodmer and James M. Burdick, Serial No. 708,733, and lay no claim to such broad combination, our present invention residing in the specific structure embodying such broad combination, as illustrated and described herein and as recited in the appended claims. Furthermore, we desire it understood that while we have described and shown a specific structural embodiment of cap, its structure may be varied in detail within the spirit of the invention and the scope of the appended claims.
