To all whom it may concern:

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

My invention relates to improvements in carriage-makers’ tools of the class usually termed “rooters;” and one object of my invention is to increase the utility and efficiency of the tool, so that it may do the work of several separate tools as heretofore constructed.
In the accompanying drawings, Figure 1 is a plan view of my tool in the form adapted to do the work of one style of rooter. Fig. 2 is a front elevation of the same, together with a piece of work. Fig. 3 is a reverse plan view of said tool. Fig. 4 is a front elevation of the same tool differently adjusted, so as to perform the work of another style of rooter, said figure also showing a piece of work. Fig. 5 is a side elevation of one side of one of the ears to which the handles are attached. Fig. 6 is a like view of that face of the handle which confronts the face of the handle-ears, Fig. 5. Fig. 6a is a transverse section on line y y, Fig. 1, of the stock of my tool, showing the other parts in side elevation. Fig. 7 is a reverse plan view of the middle portion of my tool, corresponding to Fig. 3, but with shoes or guides added thereto. Fig. 8 is a view showing the back side of the cutter for the rooter. Fig. 9 is a reverse plan view of my tool arranged for use as a boxer or paneling-tool. Fig. 10 is a front elevation of the same. Fig. 11 is a transverse section of the same on line x x of Fig. 10, and Fig. 12 is a like section of the same with the cutting-tool reversed.

A designates the stock of my implement, which stock is substantially a flat block with smooth under side and edges, having an upwardly-projecting tool-post, a, and handle-ears b b. For convenience of holding the handles B B in the desired positions, a rib, c, Fig. 5, is formed on the face of the handle-ears b b, and as many grooves, d, Fig. 6, are formed on the face of the handle-shank as may be desired, into either of which grooves the rib may enter to hold the handles in the desired position. The screw e serves as a pivot on which the handles turn after-the screw has been loosened sufficiently to let the rib c disengage the grooves. The screw alone might be depended upon to hold the handles in place; but by the use of the rib c and grooves there is less liability of displacement from any given adjustment. These screws e are substantially parallel with a transverse line across the under face of the stock, to enable the handles to be set for use in the relation to the under face of the stock shown in Figs. 1, 2, and 3, or as in Fig. 4. For most uses the handles will beset parallel with the stock A, as in Figs. 1, 2, 3, 9, and 10.

Side guides or gages, C C, are secured upon the stock A, the same being fitted to slide thereon and to be fastened in place, when adjusted, by means of the set-screws f. The stock A has an opening by the side of the tool-post a, through which the shank of the T-shaped tool D passes, said tool being held in position by the yoke E and its clamp-screw g. The two ends of the cross member of the T-shaped tool D are made hooked, as shown most clearlyin Figs. 3 and 7, to form, respectively, right and left hand cutters, either of which may be used. The shank of the tool is grooved longitudinally and fits a vertical rib on the side of the tool-post a. The gages G C can be set to have the ends of the cutters project a distance equal to the desired depth of cut.

F, Fig. 2, designates a piece of work such as the rooter is designed to groove, the implement being shown in said figure in position for forming said groove, the under face of the stock gaging the distance of the groove from the top of the work, while the gage C will gage the depth of cut. In starting a groove with the rooter, the cutter may be prevented from taking too rank a cut by canting the position of the tool with reference to the work, letting one handle fall backward and the other forward, so that the forward corner of one of the gages C may come against the work. As the groove deepens, the operator will give the tool a less canting position to feed the cutter in as fast as may be desired, until finally that part of the gage near the cutter bears on the work and the tool can cut no deeper without changing the gage.

If desired, shoes or guards k k may be secured to the under side of the gages C C just in front of the cutter, as shown in Fig. 7, so as to prevent the cutter from working too rank; but when the tool is used as above described these shoes are not essential.

In Fig. 4, G designates a piece of work of a different form, and in order to adapt the tool for this work the handles are adjusted into a position at right angles to the stock, so that the implement may be applied to the work as illustrated and then conveniently operated by the handles.

In Figs. 9, 10, 11, and 12 the implement is arranged for use as a boxer or paneling-tool. The T-shaped tool D and depth-gages C C are removed and the tool H substituted for the tool D. Like tools of varying widths are furnished, either of which may be used. This tool thus arranged may be used for sinking a box or panel or for smoothing the surface thereof. It will ordinarily be used as arranged in Figs. 9, 10, and 11; but sometimes for working in cramped places it may be desirable to secure the tool upon the other side of the tool-post a and reverse the position of the yoke E, as shown in Fig. 12.

I claim as my invention —

1. The combination of the stock A, having handles B B, the T-shaped cutter D, having a cutting-edge at each end of its cross member, whereby right or left hand cuts may be made without special adjustment, mechanism for holding said cutter, and the gages C C, substantially as described, and for the purpose specified.

2. The combination of the stock, right and left gages and cutters adapted for use in cutting lateral grooves either on the right or left side of vertical faces, and the handles B B, pivoted on axes which are substantially parallel with a transverse line across the under face of the stock and adapted to be adjusted and secured at different angles to the stock, substantially as described, and for the purpose specified.

3. The herein-described convertible rooter and boxer, consisting of the stock A, having a flat under face, the rooting and boxing cutters fltted for separate application to the stock, clamping mechanism for holding either of said cutters with their cutting end projecting below the bottom face of the stock, and attachable and detachable transverse gages for attachment to the bottom face of the stock, substantially as described, and for the purpose specified.

To all whom it may concern:

Be it known that we, CHARLES L. MEAD, of New York, in the county of New York and State of New York, and JUSTUS A. TRAUT, of New Britain, in the county of Hartford and State of Connecticut, both citizens of the United States, have invented certain new and useful Improvements in Bench-Planes, of which the following is a specification.

Our invention relates to improvements in adjusting the plane-irons laterally.

In the accompanying drawings, Figure 1 is a vertical section, partly in elevation, of a bench-plane which embodies our invention. Fig. 2 is a plan view of the same with the holding-cap removed. Fig. 3 is a face view of a portion of the frog and the laterally-adjusting lever. Fig. 4 is a vertical section, partly in elevation, showing a modification of our invention; and Fig. 5 is a face view of a portion of the frog and laterally-adjusting lever of the plane represented in Fig. 4.

We have illustrated our improvement as applied to a Bailey plane, in which the cutter is adjusted up and down by means of the lever A and the nut B; but it may be used in connection with planes having different mechanism for adjusting the cutter up and down. At the upper end of the frog C we pivot the laterally-adjusting lever D, the handle of which lies under the upper end of the cutter E. On the short end of this lever there is an upwardly-projecting pin or stud, a, the length of which pin is longer than the thickness of the cutter E and nearly equal to the combined thickness of the cutter E and the cap-iron F. In use this cap-iron and cutter are secured together by a screw in the ordinary manner. The cap-iron F is provided with a T shaped slot, (shown most clearly in Fig. 2,) the transverse portion of which slot receives the upper end of the adjusting-lever A, while that portion of the slot which extends longitudinally with the cap-iron receives the upper end of the pin a. Inasmuch as the cap-iron has but a very slight up and down movement, the slot for this pin can be made quite short. By turning the lever B to the right or left, as may be required, the upper end of the cap-iron and cutter may be carried to either side, so as to bring their edges square with the stock.

In Figs. 4 and 5 we have shown a modification of our invention, in which we have a similar lever, D’, pivoted in like manner to the frog C; but instead of having a pin in its short end said end is slotted, as shown in Fig. 5, and the cap-iron F has rigidly secured to it a pin, a’, which extends downward through the ordinary slot in the cutter and into the slot of the laterally-adjusting lever. In both constructions the laterally-adjusting lever is made to engage directly with the cap-iron, and is connected thereto by a pin-and-slot connection.

We are aware of the patents to Traut, No. 306,877, October 21, 1885; Gage, No. 323,804, August 4, 1885, and Nicht, No. 173,177 , February 8, 1876, and hereby disclaim all that is shown and described in said patents. By our improvements the construction of the laterally-adjusting lever and its connection is so simple as to be produced at the smallest possible cost. It is also as convenient to use as that of any prior plane. In these prior devices when the lever or the fulcrum block on the lever takes into the slot of the cutting-bit the end of the lever or block must be properly fitted to the slot of the cutter, and when a cutter with a slot of different width is employed the adjusting-lever will not fit it. By our improvement different cutters may be used without reference to the width of the ordinary slot in the cutting-bit.

While the Gage patent shows the laterally-adjusting lever connected with the cap-iron, it necessitates the employment of an additional element — viz., the fulcrum block — not required in our combination.

In the Traut and Nicht patents the laterally-adjusting lever bears against the side edges of the slot in the cutter at some considerable distance each side of a longitudinal line passing through the fulcrum-pin. In our device the bearing of said laterally-adjusting lever on the pin which connects its slotted end with the cap-iron is nearly on said longitudinal line, and consequently said lever works with greater ease and less friction and with less wear.

We claim as our invention —

In at bench-plane, the laterally-adjusting lever pivoted to the frog just underneath the cutter and connected directly with the cap-iron by a pin-and-slot connection, the pin of which extends through the slot in the cutter, but does not engage the cutter, substantially as described, and for the purpose specified.

To all whom it may concern:

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

This invention relates to improvements in the bit-adjusting mechanism of bench-planes; and the object of the improvement is to simplify the construction and to allow the several parts to be cheaply made and quickly assembled with but little fitting.

In the accompanying drawings, Figure 1 is a plan view of the stock or body of a plane of my new construction with cutting-bit and holding-cap removed. Fig. 2 is a vertical section of said plane on line x x of Fig. 1. Fig. 3 is a plan of the cutting-bit, and Fig. 4 an under side view of the lever by means of which said bit is moved laterally to square its cutting-edge with the stock.

The arrangement of the devices by means of which I effect both a lateral and longitudinal adjustment of the bit is believed to be new and forms an essential feature of my invention. Heretofore, so far as I know, the mechanism for adjusting the bit longitudinally has been connected directly with the cutting-bit or its cap-iron. In my improvement the lever for lateral adjustment forms the means of connecting the bit with the longitudinal adjustment, and thereby constitutes an essential part of said longitudinal adjustment.

In the drawings, a indicates the stock of the plane; b, the cutting-bit; c, the holding-cap, and d the screw provided for locking the cap and bit in their respective positions, the parts thus far named being old and well known. The solid portion,or so-called “frog,” of the stock a is inclined on its upper face at a proper angle to produce a shaving cut of the bit b, which bit rests on said frog at its lower end, and is slotted, as at e, to allow said bit to move both laterally and lengthwise without engaging the cap-screw d. That portion of the frog which is designed to receive the lever g is cut down, as at f, so that when the parts are assembled said lever lies underneath the bit with its upper surface in line with the forward part of the frog. The inner end of said lever is provided with a slot, h, which straddles a pin, i, projecting from the frog, said slot and pin forming a floating fulcrum for said lever. Between said fulcrum and the free end of lever g is a pivot-pin, k, projecting upward from said lever, and adapted to enter any one of a series of holes, m, in bit b.

Assuming, now, that we have a plane of the construction thus far described, the lateral movement of lever g in either direction will move the cutting-bit b (in the same direction) a distance proportionate to the leverage provided. In order to add to said construction mechanism for moving the bit longitudinally to govern the depth of the cut, I have provided transverse recesses or grooves n in the under side of lever g, and have connected therewith a toothed plate, o, pivoted in the stock a, and actuated by a thumb-nut, p, on a fixed screw, q. This device in itself is well known and needs no detailed description, and other known mechanism for longitudinal adjustment may be substituted therefor. It will now be understood that when it is desired to increase the depth of out the turning of thumb-nut p to the left hand will elevate the forked end of the plate o, and thus move forward lever g and the cutting-bit, to which said lever is attached by pin k.

Lever g is allowed to move lengthwise a considerable distance by the fulcrum-slot h, and as the bit becomes worn and shortened pin k may be entered in the next hole, m, of the series. To adjust bit b laterally to square its cutting-edge with stock a, the free end of lever g is swung to one side, as above noted, the action being the same as in planes of this class now in common use. When said lever is thus moved laterally, the recesses or grooves n, being of considerable length, remain in engagement with the teeth of plate o, so that the bit may be adjusted longitudinally without adjusting it laterally, or vice versa.

I am aware that a prior patent for a bench-plane shows and describes an adjusting-screw connected to and operating a longitudinally-sliding block that is clamped to the under side of the cutting-bit by a screw which passes through a fellow plate on the upper side of the cutting-bit and through the slot in said bit, which block, fellow plate, and screw form the sole means of connecting the adjusting-screw with the cutting-bit. The said sliding block and fellow plate have connected thereto a laterally-adjusting lever, the same being carried longitudinally with said block and fellow plate. Such a plane, having a laterally-adjusting lever which merely rides upon the mechanism for adjusting the cutting-bit longitudinally without forming an essential part of said longitudinal adjusting mechanism, is hereby disclaimed.

I claim as my invention —

1. In a bench-plane, the combination of the laterally-adjusting lever, the mechanism for operating directly upon said lever for adjusting it longitudinally, and the cutting-bit connected to said laterally-adjusting lever, whereby said lever forms an essential part of the mechanism for adjusting the cutting-bit longitudinally, substantially as described, and for the purpose specified.

2. In a bench-plane, the combination of the cutting-bit having a series of holes, m, the laterally-adjusting lever let into the face of the frog and fulcrumed thereon by a pin-and-slot connection, said lever also having a pin for insertion in one of the holes m, and mechanism applied directly to said lever for adjusting it, and through it the bit in a longitudinal direction, substantially as described, and for the purpose specified.

To all whom it may concern:

Be it known that I, JOHN H. SHAW, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Planes; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in —

Figure 1, a side view of the plane complete; Fig. 2, a face view of the plane-iron bed, showing the transverse adjusting-screw; Fig. 3, a back side view of the plane-iron; Fig. 4, a vertical section through the transverse adjusting-screw and in the slot of the plane-iron; Fig. 5, a modification in the support of the transverse adjusting-screw.

This invention relates to an improvement in that class of planes in which the stock is made from metal, and is provided with means for adjusting the plane-iron to give a greater or less cut. Usually the only adjustment made by the mechanism of the plane itself is to produce a greater or less extent of cut by the plane-iron; but in setting the plane-iron a lateral adjustment is necessary. This is generally produced by means of a hammer striking the edge of the plane-iron to turn it to the right or left, as the case may be, to bring it into proper relation to the face of the plane. A device has been applied to the plane by which the lateral adjustment may be produced mechanically, this device consisting of a lever hung upon the stock and engaged with the iron, so that by turning the lever to one side or the other the plane-iron will be thrown accordingly; but this adjustment is liable to displacement by accidental blows upon the lever, and is not capable of that nice adjustment which is necessary in setting the iron, and is inconvenient in many respects. In another case an endless screw has been transversely arranged across the stock of the plane, and in engagement with the same lever by which the cut of the plane is adjusted; but in this construction the adjustment by one screw is liable to be deranged by the adjustment of the other screw, because of both screws acting in different directions upon the same lever.

The object of my invention is to apply a screw for the transverse adjustment of the iron, but independent of the cut-adjusting device, whereby the nicest adjustment may be produced without liability of accidental displacement.

A represents the stock, which may be any of the usual or known constructions, and in which the plane-iron B is arranged in the usual manner and secured by any suitable device.

C represents the adjusting-screw by which the plane-iron is adjusted to produce a greater or less cut — a common and well-known device, and does not require particular description. The stock is provided with a solid bed, D, upon which the plane-iron rests, also in the usual manner. In the stock, above the point where the adjusting device engages the plane-iron, (E representing the opening in the bed through which the adjusting device engages the iron,) I arrange a transverse screw, F, there being a transverse recess, G, formed across the bed for this purpose. In the recess in the bed one or more bearings, a, are formed for the screw, the seats in these bearings being of less diameter than the body of the screw. The screw itself is constructed with annular grooves b, corresponding to the bearings a, and so that laid into the bearings, as indicated in Fig. 2, the screw may rotate in the bearings, but held by the bearings against movement in an axial direction.

The outer end of the screw is provided with a suitable head, H, by which it may be turned. On the screw is a nut, I, adapted to slide through the recess in which the screw is applied, the nut being internally screw-threaded corresponding to the thread of the screw, and because the nut can not revolve in the recess, owing to its shape, as seen in Fig. 4, it follows that the rotation of the screw will impart to the nut a transverse movement, according to the direction in which the screw is turned. The nut projects above the face or bearing-surface of the bed and enters the slot J in the plane-iron B, the length of the nut corresponding to the width of the slot, the slot being of a standard width in all irons adapted to a certain size plane.

When the plane-iron is secured in the stock in the usual manner, if it be desired to impart transverse movement to the iron in either direction, the screw H is turned accordingly, and through the nut I imparts such required transverse movement to the plane-iron, and when once set there is no liability of accidental dis-adjustment, and the most perfect adjustment may be made by the screw, much more so than can be produced by a lever which is turned by hand or by blows imparted to it.

The bearings a in the recess in the bed are equidistant from the center, so that the screw may be introduced with its head either to the right or left, as indicated in Fig. 2, solid lines indicating the left-hand position and broken lines the right-hand position. The bearings are simply of U shape, open outward, as seen in Fig.2, so that the screw may be dropped therein. The adjusting device is therefore readily removable from the plane should occasion require.

It will be understood that the transverse adjustment may be applied to a plane with any of the many different vertical adjustments, or without vertical adjustment should it be desired.

While I prefer to construct the recess with the bearings a, into which the screw may be dropped or readily removed, as I have described, it may be supported permanently in the recess, as seen in Fig. 5, it only being essential that when the screw is in its place it shall be prevented from movement in an axial direction, yet left free for rotation, and carry the nut.

From the foregoing it will be understood that I do not claim, broadly, the combination, in a plane, of a transverse or lateral adjusting-screw for the plane-iron.

I claim —

In a plane substantially such as described, the bed upon which the plane-iron rests, constructed with a transverse recess, G, and with one or more bearings, a, therein, combined with a screw, F, constructed with annular groove or grooves corresponding to said bearing or bearings and adapted to set therein, the said screw provided with a head upon its outer end, by which it may be rotated, a nut, I, in said recess and upon said screw, but independent of the cut-adjusting mechanism, the said nut adapted to engage the plane-iron, substantially as and for the purpose described.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, and a resident of New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bench-Planes, which improvements are so described in detail in the following specification as to enable others skilled in the art to which they pertain to make and use the same, reference being also had to the annexed sheet of drawings, in which —

Figure 1 is a plan view of a plane-stock with bit-adjusting devices attached thereto, the position of the bit being indicated in dotted lines. Fig. 2 is a side elevation of a plane, with a portion of the stock (on line x x, Fig. 1) in section to expose the operative parts of the tool.

These improvements are applicable to bench-planes in which provision is made for both lateral and longitudinal adjustment ofthe cutting-bit, a familiar type of said planes being shown in my former patent, No. 306,877, of October 11, 1884. In said former patent I have experienced some inconvenience in pivoting the lever which provides lateral adjustment of the bit, and also in combining in a practical manner said lever with certain forms of mechanism for providing longitudinal adjustment.

My present improvements are intended to overcome these defects and to utilize in the best possible manner the limited space devoted to these mechanisms.

Referring to the drawings, the letter a indicates a plane-stock, b the notched plate by which longitudinal adjustment of the bit c is attained, d the thumb-nut which actuates said plate, and e the screw which holds the cap-section k in place, said section being brought into bearing on said bit by means of the cam f which is pivoted thereto, all of these parts being old in this class of planes.

Immediately below the bit c is located a lever, g, whose inner end is perforated and preferably tapped to fit the threaded portion of screw e. This screw is thus made to serve as the fulcrum of said lever, and simplifies in a considerable degree the construction of the plane. When tapped out, as above stated, the fit should be loose enough so there will be no tendency to turn and loosen screw e as the lever is swung from side to side. By threading the hole in the lever and pivoting it on the threaded portion of the screw, the lever is always held in proper position on the frog, so that it will not become displaced when the cap-section is removed. Said lever is formed with an integral upwardly-projecting rib, h, which enters a slot in bit c (shown in dotted lines in Fig. 1) and acts to move said bit substantially the same as the lever in my said former patent, with this exception, that in the present instance the manner of pivoting forms a lever of the second order instead of the first, as before. Lever g, as it leaves the fulcrum-screw, is bent laterally and extends rearward at one side of the notched plate b, and is then preferably brought back into the same vertical plane as the pivoted end first described. (See Fig. 1.) This laterally-bent form of adjusting-lever allows me to enlarge, strengthen, and alter the mechanism provided for longitudinal adjustment of the bit, and to adopt other means of longitudinal adjustment which would lie in the path of straight levers as now commonly used.

Having described my improvements, I claim as new and wish to secure by Letters Patent —

1. In combination with the stock and cutting-bit of a bench-plane, a lever for laterally adjusting said bit, fulcrumed on the screw which secures the cap section, in substantially the manner and for the purpose herein specified.

2. In combination with the stock and bit of a plane, a lever for laterally adjusting said bit, said lever being tapped to fit and fulcrumed on the cap-screw, substantially as and for the objects specified.

To all whom it may concern:

Be it known that I, EAMOR A. TEED, a citizen of the United States, residing at Lowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Bench-Planes, of which the following is a specification.

My invention relates to bench-planes; and it consists in the means, hereinafter described, whereby the stock of the plane may in effect be lengthened to enable one plane to serve the purpose of one or more planes of greater length than the plane to which the improvement is applied.

In the accompanying drawings, Figure 1 is an isometric perspective view of a plane with my improvement applied thereto; Fig. 2, an isometric perspective view of my improvement detached; Fig. 3, a vertical cross section on the line x x in Fig. 5; Fig. 4, a central longitudinal section of the rear part of the plane proper and the rear part of my improvement; Fig. 5, a central vertical section of my improvement and a side elevation of the plane.

The improvement, hereinafter described, may be applied to any so-called “iron bench-plane” — that is, a bench-plane having an iron stock — and is here shown as used in connection with a “Bailey smooth-plane,” the construction of which is well known and needs no particular description.

lt is sufficient to say that A represents the stock, a the plane-iron, and H H’ the plane-handles.

The only change that requires to be made in the plane proper to enable my improvement to be applied to it is to form two grooves, a’, one on each side of the stock leading from near the point of the same to said point, and providing the handle H’ with a depression, h, for purposes hereinafter stated.

My improvement consists of a shoe, S, which in general appearance is like the bottom and sides of the stock, but longer, and provided with an opening, s, through the bottom of the same, of a shape and size adapted to receive and fit the sole of the stock A. The shoe S is provided with pins s’, (shown in Figs. 2, 3,and 5,) adapted to enter the grooves a’ and to fit the same, and is also provided with a vertical post, s2, arranged in the rear of the slot s, which vertical post supports an inclined screw, s3, the head s4 of which is preferably milled to enable it to be turned readily by the fingers, the point of said screw entering the depression h, above mentioned as being formed in the handle H’, to prevent the rear end of the plane from rising out of the slot s. The relative positions of the grooves a’, pins s’, screw s3, and depression h, are such as to hold the sole of the stock A and the bottom of the shoe S in the same plane, the rear ends of the grooves a’ being at the same height above the sole of the stock as the pins s’ are above the bottom of the shoe, and the deepest part of the depression h fitting the point of the screw s3 and being at the same height above the sole of the stock as the point of said screw, when turned into said depression, is above the bottom of the shoe. The depression h, instead of being made directly in the wood of the handle, is preferably made in the head of a metallic screw, h’, driven into the handle against the screw h2, which secures the handle H’ to the detachable face-plate.

The plane is inserted in the shoe-point first and pushed forward until the pins s’ reach the rear ends of the grooves a’, and the rear of the plane is then depressed until the lower surfaces of the stock A and the shoe S are in the same plane. loosening the screw s3 the rear end of the plane may be lifted out of the slot s, and the stock being then drawn backward is disengaged from the shoe.

By means of the improvement above described a common smooth-plane can be used with the shoe as a fore-plane or jointer, and the expense of such a shoe is trifling compared with the cost of a plane, and the time required to apply or remove the shoe is of no importance.

I claim as my invention —

1. A shoe provided with a slot adapted to receive a plane-stock and means, substantially as described, of holding the bottom of said shoe in the same plane with the bottom of said stock, as and for the purpose specified.

2. The combination of the plane having a handle, and having a stock provided with grooves near its point, and a shoe slotted to receive said stock, and having inwardly-projecting pins adapted to enter and fits said grooves, and having a post, a screw turning in said-post and thrusting into a depression with which said handle is provided to hold the lower surfaces of said stock and shoe in the same plane, as and for the purpose specified.

To all whom it may concern:

Be it known that I, JAMES H. POLHEMUS, of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Spokeshave, of which the following is a full, clear, and exact description.

My invention relates to an improvement in spokeshaves, and has for its object to provide a tool capable of use as readily in curves of small radius as upon a flat surface.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully described, and set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a plan view of my spokeshave, and Fig. 2 is a central transverse vertical section through line x x of Fig. 1. Fig. 3 is a horizontal section through the central portion of my tool, with the clamp removed and the surface of the blade exposed.

At each side of the central portion of the tool A, having the ordinary handles, a, and transversely the said tool, vertical ears B are formed, provided near their upper edge with a segmental slot, b, and a parallel integral transverse offset, C, upon their inner face at the base, which offset is more or less concaved at its outer end.

In the body D of the tool, intervening the ears B, a more or less V-shaped central recess, d, is produced, which recess is out entirely through said body at the inner end thereof, as illustrated at d’ in Figs. 1 and 3. Within the recess d a pin, e, is secured, upon which pin an angle-lever, E, is pivoted at the intersection of its arms, the short arm of said lever being adapted to reciprocate in the recess d, and having a stud, F, made integral with its upper face near the end, the long arm of said lever being provided with a thumb-rest, f.

A knife, G, having a central slot, g, is made to slide in the body surface D between the transverse offsets C of the ears B. The knife G is also provided with a series of small rectangular slots, H, arranged to the rear of the large slot g, in central alignment therewith, about the sixteenth of an inch intervening each of said small slots, and also the foremost one and the large slot g. When the knife is inserted, as aforesaid, the stud F upon the angle-lever is made to enter the first or foremost rectangular slot H, as shown in Figs. 2 and 3. As the knife becomes narrowed by sharpening and use, the remaining slots H may be brought into contact with the stud F.

The object of the lever-connection with the knife is to adjust the knife-edge, as in a plane, the desired distance over the front edge of the body surface D.

A clamping-plate, K, of substantially the same shape as the knife, provided with an outer beveled edge, k, and a central elongated slot, k’, is made to rest upon the knife G, clamping the same in a given position by means of a screw, L, which, passing through the slot k’ of the clamp-plate and the large slot g of the knife, is screwed into the body D, as shown in Fig. 2.

A guide, M, consisting of the longitudinal bar m, having a flat under surface, m’, and more or less round corners, m2, and provided with integral arms m3 at right angles thereto, is adjustably held within the ears B by thumb-screws N, entering the slots b in said ears and also the arms m3 of the guide at their ends. When the guide M is thus positioned, the flat under surface m’ thereof is normally in the same horizontal plane with the under flat surface n of the body D. A space is, however, made to intervene the opposing edges of the said body D and the guide.

In operation, by pressing with the thumb against the lever E the knife is adjusted as desired and set by the body-screw L. If a plain surface or curve of large radius is to be dressed, the arms of the guide M are secured in the upper corners of the segmental recesses b, as shown in Fig. 2. In this position the device acts as an ordinary tool of its kind. When, however, it is desired for use upon a curve of small radius, the arms of the guide are carried as far down the slot as thought proper, which action throws the under surface of the guide at an angle to the flat under surface of the body, permitting a manipulation of the tool in short curves or in apertures large enough to admit the tool.

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

1. In a spokeshave, the combination, with the body D, provided with the ears B, having curved slots b, and the blade adjustable on the upper face of the body D between said ears, of the guide M, consisting of the longitudinal bar m, pivotally connected at its ends to the ears B adjacent to the lower end of the blade, and formed with the arms m3, having threaded apertures in their upper ends, and the set-screws N, passing through the slots b into said apertures, substantially as set forth.

2. In a spokeshave, the combination, with the body D and a guide, of the blade G, having slots H g, the lever E, pivoted to the body and having a stud, F, entering the slot H, the clarnping-plate K, having a. slot, k’, and the set-screw L, extending through the slots k’ g into the body D, substantially as set forth.

3. A spokeshave comprising the body D, having the V-shaped slot d’ in its upper face, the ears B B, having slots b, the U-shaped guide M, pivoted at the lower ends of its side arrns, m3, to the lower ends of the ears, and set-screws passed through the slots b into the upper ends of said arms, the lever E, pivoted at e within recess d’, and having a pin, F, the blade G, having a slot, g, and a series of slots, H, into one of which pin F projects, the clamping-plate K, having a slot, k’, and the set-screw L, passed through the slots k’ g into the body, substantially as set forth.

To all whom it may concern:

Be it known that I, EDWARD B, SHEPARDSON, a citizen of the United States, residing at Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Gages for Wood-Working Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is an improvement in gages as attachments to woodworking planes; and it has for its object to provide an attachment to planes of hollow metal construction, one part of which is adjustable about an axis of motion to any required angle with reference to the bottom surface of the plane to which said gage is attached, so that a guide will be formed to fit against one surface of the material and slide against the same as the bottom of said plane rides over an edge of said material, cutting the same and forming an angle with reference to anotherside of said material greater or less than a right angle.

Mechanics who are in the habit of using wood-working tools are familiar with the difficulties encountered in beveling the edge of a board where the eye and feeling or judgment alone are depended upon in making the required angle. It is desirable, in view of such difficulties, that a good and simple device be provided, so that the operation of beveling may be only mechanical. Such devices have been invented, I am aware, as applicable to planes the stocks of which are of wood. My gage is intended to be applied to a plane the stock of which is of metal. My gage is formed, in the main, of two pieces of metal hinged together. One of said sections consists of a horizontal bar having at each of its two ends projections of T form, the bar, with its two ends, forming an H, as seen from the outside. Each of the T ends is bent inward nearly at right angles. The upper of these bent ends forms lugs for clamping-screws, and the lower of said bent portions is slotted and connected by a bracing-bar. The lower part of the gage is composed of a bar of U shape, the inner plane-surface of which is smooth, and the ends of said bar form tongues, which enter the slots in the upper portion of said gage where the two said parts are hinged together. Bifurcated pieces, forming clevises, project outward from the H -bar and the U -bar, and in these are pivoted or hinged screw-threaded nuts. A right-and-left screw provided with a thumb-piece on its center engages these nuts, and when operated increases or diminishes the angle between the two parts of the gage.

In my drawings, Figure 1 is an elevation of the gage as seen from the outside. Fig. 2 is a transverse vertical section of the same, showing the application of the gage to a plane and the relation of the latter to a piece of material being beveled.

Similar reference-letters indicate like parts in both of the figures.

Referring to the drawings, A is the horizontal bar of the upper portion of the gage, and B B’ are the T ends ofthe same, provided with bent portions a a’ b b’, the latter of which are connected by the strengthening-bar C.

d d’ are slots formed in the bent ends b b’, which receive the tongues e e’ of the lower portion of the gage.

D is the lower portion of the gage, formed as previously stated, the tongue ends of which are hinged in the slots of the T-pieces B B’. The long bar of the upper portion of the gage and the curved bar of the lower portion of the same have projecting from their centers outward bifurcated pieces or clevises E E’. In the outer ends of these clevises are pivoted swivel-nuts f f’, adapted to receive the right and left ends of the double screw F.

The bent T ends a a’ have screw-threaded openings to receive the screws G G’, the clamping ends of which latter may be threadless.

In applying this gage to a plane I place the bent portions a a’ on one of the side walls, with the long bar A resting against the outside of said wall and the clamping-screws — not yet driven down — against the inside of the same. The gage should be so placed upon the plane that one of the clamping-screws shall be in front of the handle and the other rearward of the same. When the screws are driven down to place, they impinge upon the bottom plate of the plane and draw the bent ends b b’ of the gage up against the bottom surface of said plane, and the gage is thus firmly held to place.

It may be observed that the interior angles between the T-pieces and portions a a’ are less than right angles, so that the screws when driven home find their places in the angle of the plane formed by the inner surface of the bottom and the inner surface of the said side wall. The gage being thus firmly secured to the plane, when the angle of the bevel to be made is determined the lower or U -shaped bar of the gage is moved about its axis by the right-and-left screw G G’ until the proper angle is formed. The gage is now applied with the plane to the piece of material to be planed in such a manner that the inner surface of the U-shaped bar rests against one side of said material and the bottom surface of the plane upon the edge of the same to be beveled.

The operator has only to keep the gage upon the guiding-surface of the material as he operates the plane to insure accurate work.

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

In a gage for use with wood-working planes, the combination, with the upper portion provided with clamping-screws, a swivel-nut, and jaws or bearings for the same, of the lower portion of said gage hinged to the said upper portion, provided with a swivel-nut and jaws or bearings for the same, and the right-and-left screw engaging said swivel-nuts to adjust the two portions, the one with reference to the other, as and for the purpose set forth.

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

To all whom it may concern:

Be it known that I, LESTER A. DEARTH, of Laconia, in the county of Belknap and State of New Hampshire, have invented certain new and useful Improvements in Hand or Jack Planes, of which the following is a specification.

My invention relates to jack or hand planes, and has for its object to provide improvements in devices of that kind whereby the sole of the plane may be oiled (as is necessary in some classes of work) during the operation of smoothing or planing lumber therewith, and without the necessity of stopping work and employing a device separate from the plane itself for that purpose.

As is well known to carpenters, joiners, and others skilled in arts requiring the use of planes, it is essential in many kinds of work to oil the sole of the plane, and in instances where this thing is necessarily frequent much time is consumed thereby, as well as annoyance occasioned to the workman.

In carrying out my invention I utilize the knob secured to the upper face of the stock just in front of the slot provided for the escape of shavings as an oil-reservoir, in addition to its present uses, and combine means with said knob whereby the workman can from time to time, and while using the plane in the ordinary manner, supply oil to the sole thereof as may be needed.

I will now proceed to describe my invention, so that others may be able to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming a part of this specification, the same letters indicating the same parts wherever they occur, and the invention being particularly pointed out in the claims hereunto appended.

Of the drawings, Figure 1 represents a perspective view of a plane having my improvements applied thereto. Fig. 2 is a longitudinal vertical section thereof.

A indicates the plane-stock, provided with the usual handle, B, and cutting iron or tool C, adjustably secured to operate in the slot D, provided for that purpose and for the escape of shavings.

E represents the knob applied to planes as new commonly constructed, which knob is attached to the stock just in front of slot D. I construct knob E of metal or other suitable material and make it hollow, as represented in Fig. 2, providing the interior with a short tube, e, extending up from a central point at the bottom thereof, and form a hole of desired size in the top over tube e, the hollow of which latter feature extends through the bottom of the cup.

f represents a stem adapted to fit closely in tube e and to slide thereon, a spiral spring, g, surrounding said stem above tube e, and bearing at its lower end on the upper end of said tube and pressing at its upper end against a pin, h, extending through the stem, whereby the stem f is pressed upward in the tube, pin i, extending from the stern through a slot, j, in the tube, serving to limit both the upward and downward movement of the stem.

k represents a plug constructed to closely fit and slide in the hole formed in the upper end of the knob, as aforesaid, and adapted to be screwed into the upperend of stem f, or otherwise connected therewith, which plug serves both as a stopple to the hollow knob and affords means for gaining access to the interior thereof and as a contrivance whereby stem f may be depressed against the tension of spring g, operating as hereinabove explained.

f’ represents a packing of any suitable character arranged in a groove formed in plug k, or between two disks comprising the same, whereby the plug may be made to fit the hole in which it works in an oil and air tight manner. A small hole or bore, l, is made in stem f which hole extends vertically upward for a short distance from the lower end thereof, and then horizontally outward through the side of the stem, and a hole, m, is formed through the side of tube e, at the lower end thereof, constituting a valve, all as clearly represented in Fig. 2, the construction and arrangeinent of these last mentioned features being such as that when stem f is depressed by bearing on plug k bore l will be brought into range with hole m, and oil with which it is designed to fill knob E (made into a cup, as explained) will flow through said bore and down through a hole, n, formed in the stock to the sole of the plane — in the present instance shown to be just ahead of the cutting-tool.

The manner of using the invention will now be readily understood. The knob being filled with oil and the parts being arranged in position, as shown, the operator from time to time, as it may be necessary to oil the plane, as aforesaid, and without stopping his work, depresses stem f for a moment by pressing a thumb or finger thereon, releasing a drop or so of oil, which runs down through hole n, in the stock to the proper point on the sole of the plane.

By the means explained a material amount of time is saved to the workman, and by utilizing the knob common to nearly all classes or kinds of planes my invention is made cheap of construction and ready of application, as well as convenient in use.

Although I have been particular to describe the precise form and arrangement of the parts as here comprising my improvements, it is obvious that these may be varied within the limits of mechanical skill without departing from the nature or spirit of my invention.

Having thus described my invention, what I claim is —

1. In a plane, the combination, with the stock, of the knob thereon, made hollow or formed as an oil-cup, a valve in said knob or cup, and a spring-pressed stem or plug extending to the exterior of the knob, whereby the valve may be operated to release oil from the cup to oil the sole of the plane, as set forth.

2. In a plane, the combination. with the stock, of the knob thereon, made hollow or formed as an oil-cup and provided with the tube e, having hole m, and spring-pressed stem, f fitted to slide in said tube and provided with bore or hole l, substantially as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 19th day of March, 1887.

To all whom it may concern:

Be it known that I, SAMUEL BENSON, a citizen of the United States, residing at Allegheny City, in the county of Allegheny and State of Pennsylvania, have invented certain, new and useful improvements in Spokeshaves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to an improvement in spokeshaves, the object being to provide a means whereby the blade may be easily adjusted or detached from the handle of the tool; and with this end in view my invention consists in certain details of construction and combination of parts, as will be fully described hereinafter.

In the accompanying drawings, Figure 1 is a plan view of my improved spokeshave constructed in accordance with my invention. Fig. 2 is a rear side elevation of the same. Fig. 3 is a perspective view of a portion of the blade, showing the projecting end used for securing the blade to the handle. Fig 4 is a perspective view of one of the bolts for attaching the blade to the handle.

To put my invention into practice and give the same bodily form, I provide a handle, a, of suitable size and form of construction, having a metallic plate, b, embedded into the same immediately back or at the rear of the cutting-blade c. This plate b is a wear-plate, and prevents undue wear of that part of the tool which bears upon the spokes in the operation of shaping them. At the front of this plate b, I place the knife or blade c, mounted on two small horizontal plates, d, secured a short distance below the general level of the handle a. On each end of the knife cis formed a projecting flange or lug, g, which, in conjunction with two flat-head bolts, k, placed at either end, affords a means of securing the knife or blade c to the handle a. By shifting this knife c back from the inlaid plate b a coarse shaving is taken from the work; or the knife c may be elevated by placing small strips of paper or other substance between the plates d and the projecting flanges g of the knife c. This knife or blade c may be readily taken from the handle a for the purpose of sharpening or grinding, by loosening the thumb-nuts l on the end of the bolts k.

I am aware that it is not new in spoke-shaves to secure the knife to the stock by slipping its ends into grooves formed in the stock and using at one end of the knife a clamping-bolt. I therefore disclaim such a device.

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

ln a spokeshave, the combination consisting of the handle a, having a metallic plate, b, embedded therein, the knife or cutting-blade c, provided at either end with flat projecting flanges g, the horizontal plates d, and flat-headed bolts k, provided with thumb-screws l, substantially as and for the purpose set forth.

_________________

To all whom it may concern:

Be it known that I, JOHN BRICE, a resident of Sandy Hill, in the county of Washington and State of New York, have invented certain new and useful Improvements in Bench-Planes; and I do hereby declare that the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in bench~planes, and its object is fully explained in connection with the drawings.

The invention consists of the novel construction and combination of parts hereinafter described, and pointed out in the claims.

Figure 1 of the drawings is a top plan view of my improved plane. Fig. 2 is a vertical longitudinal section taken at the broken line x x in Fig. 1. Fig. 3 is a top plan view of my improved locking-lever. Fig. 4 is a side view of same. Fig. 5 is a plan view of attachment d detached.

Similar letters refer to similar parts in the several figures therein.

Numerous devices have been heretofore constructed for angularly adjusting the bit of a bench-plane and for securing the same in place in its frame or stock. They have generally been complicated in structure and expensive of manufacture, requiring special and differing forms of structure in the stock, the latter being generally made of metal.

In the construction of my improved device I am able to make use of the old and well-known wooden stock so generally in use, as well as the bit, or bit and back plate, used in connection therewith, and thus greatly improve such planes with very little expense.

My improved planes can also, when desired, be made wholly of metal or any other desirable material.

A is the stock, made in the well-known form usually adopted for wooden stocks, having the chip-opening E, inclined bit-abutment F, and upwardly-widening rearwardly-inclined side recesses, a’ a’, forming inclined ledges a a on each side of the chip-opening.

The bit B, which has a back plate, C, secured thereto by a set-screw, g, adjustable in its slot b’, is inserted through the opening in the usual manner, as shown.

Instead of driving a wedge down between the bit or plate C and the projecting ledges a a, to bind the bit in place, as has been done heretofore in such stocks, I make use of the locking-lever D, preferably metallic, and in the form of a plate convened on its upper side, substantially as shown.

I slide the lever down between the back plate, C, and the ledges a to about the position shown in Figs. 1 and 2.

The side of the lever contiguous to the plate C may have its surface plane or concave, as shown by dotted line in Fig. 4; but the opposite side contiguous to the ledges is convexed. The degree of convexity may be varied as desired.

At or near one end of the lever I provide the aperture f, preferably threaded, and adapted to receive the threaded adjusting screw b, the screw passing down through the aperture and resting upon the bit or its plate C.

When desired, a threaded nut, n, (shown by dotted lines,) may by employed, when it will not be necessary to thread the aperture in the lever.

By means of the adjusting-screw the upper end of the lever can be forced away from the plate C, the lower end of the screw resting upon the plate, and the lever traveling up the thread of the screw until the parts are securely locked in place, the central portion of the convexed lever ending a fulcrum upon the ledges a a, and the lower end of the lever bearing upon the lower end of the bit or its plate. I am able also to secure an angular adjustment of the bit by means of the attachment or plate d, extending above the top of the stock, provided with the adjusting-screw e, threaded to fit the threaded aperture i, having a head, e’, on which the bit has bearing. This attachment is preferably countersunk in a longitudinal recess, a”, in the upper or rear portion of the abutment F, to occupy a position about parallel with the bit, and may be secured by screws d’, passing through apertures j, as shown.

The upper end or head of the screw bears against the lower side of the bit, and when operated forces the bit up to the desired angle, the screw b being turned back, as required.

The convexity of lever D permits the angular adjustment of the bit to any desired degree without impairing the perfect operation and effectiveness of the lever as a locking device.

I am thus able to produce a new and improved plane by adding the loclring-lever D, with screw b, and the attachment d, with screw e, to a common and well-known device.

I do not broadly claim an angularly-adjustable bit nor a bit-locking lever.

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

1. The combination of the stock A, formed with a chip-opening, E, inclined rear abutment, F, having correspondingly-inclined longitudinal recess a”, upwardly-widening inclined side recesses, a’ a’, forming inclined front abutments, a a, projecting into the chip-opening, the fixed plane plate d, secured in the longitudinal recess and projecting above the stock, an adjusting-screw, e, inserted in the projecting portion, having a head, e’, a bit, B, supported on the inclined rear abutment and on the head of the adjusting-screw, the back plate, C, adjustably secured to the bit, and the lever D, located at the rear of the chip-opening, having a convex upper side bearing against the front abutments, its lower end bearing on the lower end of the back plate, and an adjusting-screw in the upper end of the lever bearing on the middle portion of the back plate, the bit, back plate, and lever all being of the sanie width and the side recesses being common to all, substantially as shown and described.

To all whom it may concern:

Be it known that I, HENRY F. STEARNS, a citizen of the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Routing-Tools for Workers of Wood, of which the following is a specification.

My invention relates to improvements in routing-tools in which the stock is provided with a mouth having on one of its sides a way for holding the cutting-tool and a wedging-piece and an adjustable gage working in the arms of the tool, all of which I will hereinafter particularly describe and set forth; and the objects of my invention are to provide in a routing-tool adjustable and interchangeable cutting-tools, which will be securely held from shifting in the mouth of the tool and have the gaging devices adapted to be variously adjusted and set at either right or left hand side of the cutting-tool and at any desired distance therefrom as the work to be done may require. I attain these objects by the mechanism illustrated in the accompanying drawings, in which —

Figure 1 is a view of the tool from above. Fig. 2 is a longitudinal sectional elevation. Fig. 3 is a cross-section taken at line 1 in Fig. 1. Fig. 4 is a view of the mouth of the stock with the cutting-tool and wedge removed, and showing the tool-guiding way. Fig. 5 is a plan view of a cutting-tool and an end view of the same, showing the coacting way made therein.

The same letters of reference refer to like parts throughout the several views.

The stock A, arms A’, and handles A2 A2 of this tool may be made in one piece of malleable iron, or be made of wood and iron combined, if preferred. The stock A is made with a gradually-contracting mouth, B. Across the upper portion of this mouth, and arranged slightly to one side of the center of its width and running longitudinally in direction of arms A’, is bar b, preferably made solid with the end walls of said mouth, or securely fixed therewith. Made with the rear side wall, a, of this mouth is the way c, which is shown in Figs. 3 and 4 to project a short distance past the plane of said rear wall.

C is the cutting-tool, made with any form of cutting bit or edge usually employed for grooving, channeling, beading, or forming moldings, or for incising. Made central in the width of this cutting-tool and in its rear side from its upper end, or near the cutting bit or edge, is the way c’, corresponding in size and form with way c, made with the rear wall, a, of mouth B, so that the former will receive the latter and permit the shank of the tool to have a full bearing on the surface of wall a of the mouth of the tool. These ways may be made to be reversed in their respective forms by making that in wall a of mouth B in the form of a groove instead of a projection, as shown, and that in tool C in the form of a projection instead of a groove, as shown. These ways c c’ in the respective pieces co-operate together to hold the cutting tool or blade C from shifting or being moved out from its normal set position in the mouth of the stock, and allow a variety of tools or blades, C, of differing widths to be employed within mouth B without the least liability of shifting when the tool is being operated.

D is the wedge, having a shallow groove, d, running across its front side, as shown in Fig. 3, for engagement with holding-bar b. The lower end of this wedge is made with an incline, as shown in the same figure, so as to permit an opening between the tool or blade below and the front wall of mouth B, for passage of the shavings from the cutting bit or edge of the blade C. In the upper end portion of this wedge D is made a screw-threaded hole, into which works the set-screw f by which, through wedge D, the cutting tool or blade C is securely held in its adjusted position and length of projection below the sole or face m, of the stock, which face is curved in its surface. Made in arms A’ A’ are slots E E, extended to any preferred distance from stock A toward handles A2.

F is an adjustable gage-lip provided with a projection, g, which nicely fits in slots E, for holding with the same to prevent the gage-lip from shifting sidewise. This projection is made with tail-piece F’ of the gage-lip, and has projecting upward from it the screw-threaded stem h. Nicely fitting this stem h is the screw-threaded finger-nut H, for securing this gage-lip at any point distant from the cutting tool or blade C. This gage-lip and its holding device are adapted to be used in the slot E of either of the arms A’, as may be required for right or left hand work.

By my above described improvements I obviate the use of several different bodies of routing-tools as heretofore required by carriage-makers, cabinet-makers, and other workers of wood for different operations or kinds of work, and with a variety of cutting blades or tools, C, provided each with a suitable form of cutting edge or bit, a workman can form in the wood on straight or curved lines, and on the right or left hand edges of the pieces, grooves, channels, beads, moldings, flutings, or other raised or sunken surfaces, as may be required.

The mouth of the router, being arranged to be vertically over the cutting-bit of tool C, will deliver the shavings upward from the same in a free manner instead of in a forward direction, as is usual in routers heretofore made, and the shavings will be freely delivered from the cutting-bit and without the least liability of choking the tool, as heretofore. The coacting ways c c’, made with the rear side wall of the mouth of the stock and the rear side of the shank of the cutting-tool C, operate to hold that tool firmly from shifting in any direction, and the bar b, operating with the groove d of wedge D, holds the latter from moving in either direction end wise, While the wedge D, with the set-screw f operates to hold the tool or blade C secure to its place, with its cutting-edge projecting below the sole of the stock to the point adjusted to without the least liability of its being raised, and also allows this cuttlng-blade to be readily set to cut deeper from time to time, as may be required in the progress of the work.

The spokeshave-blade can readily be applied and be firmly held and shifted in either direction in relation to the month of the stock A. The stock, with its slotted arms and handles, operating to serve as the body of a spoke-shave, being well adapted to receive the above-described shaving-blade S, obviates the use and expense of a special and individual stock, as heretofore required.

The stock A and its mouth B may be made of any suitable length, so as to receive two or more cutting-tools, C, for grooving or incising or beading two or more surfaces at a time, as may be preferred. The curved surface of face m of the stock running from one side to the other enables the operator, by slightly turning the stock, to cut with a greater or less depth into the wood, and thereby obviates the necessity of setting the cutting-blade C (for making different depths of cuts) several times before finishing the work being done.

If preferred, a small bracket, z, made with the rear side of the stock, and provided witli a set-screw, x, working in its head end, and its lower end working in a small sleeve attached to the upper end of the tool C and held by a key, may be employed ibr raising or lowering the tool, as is the practice with irons in planes.

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

In a routing-tool, the combination, with a stock provided with similarly-slotted arms, which are extended in opposite directions from the tool mouth, of an adjustable gage-lip, which is provided with a screw-threaded stem and nut and constructed to be used interchangeably in said slotted arms, a cutting-blade which is provided on its rear side with the way c’, which engages with way c, made with the rear side wall of tool-mouth B, and the mechanism described for adjusting and securing said cutting blade in said tool-mouth, substantially as and for the operations and purposes set forth.

To all whom it may concern:

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

My invention relates to improvements in bench-planes, and has particular relation to the manner of holding the cutting-bit within the stock.

One object of my improvement is to produce a plane in which the bit can be clamped by fewer and more direct motions, and therefore more conveniently, than heretofore.

In the accompanying drawings, Figure 1 is a plan view of my plane. Fig. 2 is a side view of the same, partly in section and partly in elevation. Fig. 3 is a like view with the holding-cap placed in position with its lever raised ready for clamping the bit. Fig. 4. is a plan view of my holding-cap and its lever detached from the plane, and Fig. 5 is a like view of the reverse side of the same.

The stock A and the means for adjusting the cutting-bit after it is clamped within said stock may be of any ordinary construction.

B designates a headed screw set in a threaded hole in the frog or stock in the ordinary manner of this class of planes, so that by screwing it in or out the distance between the under side of the screw-head and the upper side of the cutting-bit C may be adjusted. A fixed stud with an adjustable head or a headed bolt adjusted by a nut would be the equivalent of this screw.

D is the holding cap or wedge, having a hole near its center, as viewed in plan view, which hole is large enough to let the head of the screw B pass through it. Pivoted to this cap by means of the pintle a is the clamping-lever E, the upper end of which is preferably of a form which will serve as a handle for the plane, while its lower and short end is slotted to take under the head of the screw upon two sides. The slot in this lever opens into the central hole in the cap. Said slot also extends both forward and backward of the pintle a, and hence said pintle is in two parts — one on each side of said slot — as indicated by the broken lines in Fig. 5.

The holding-cap is so formed on its under side as to bear upon the cutter only at the ends of said cap. After setting the bit in place the holding-cap and attached lever are placed on the bit (or on the cap-iron in case of a double plane-iron) by letting the central hole pass over the screw-head, then slipping the holding-cap downward to let the slotted end of the lever under the head of the screw, as shown in Fig. 3. The long end of the lever E is then depressed, when said lever fulcrums on the under side of the screw-head and carries the holding-cap downward into the position shown in Fig. 2, in which the pintle a (indicated by the broken circle) is slightly in advance of the lever on the screw-head, and consequently the pressure on the screw will hold the lever in its clamping position. If the adjusting-screw is properly set, the bit will be then firmly clamped. In putting in the clamping device the operator takes hold of the handle only and sets the holding-cap in place, then merely presses the outer end of the handle obliquely downward with only one motion. It will thus be seen that in clamping the bit the movement of the cap and lever-handle is practically in the same direction — forward and downward — and therefore these parts are more conveniently handled than parts which require to be moved in reverse directions — as, for instance, when the lever requires to be first moved backward and upward, as is the case in several prior planes. The clamping mechanism is also believed to be very efficient.

I claim as my invention —

In a plane, the combination of the holding-screw B, the holding-cap D, adapted to bear at each end upon the bit, and the clamping-lever pivoted or hinged to said cap between the bearing ends and having its upper face adapted to engage and fulcrum upon the under side of the screw-head, substantially as described, and for the purpose specified.

To all whom it may concern:

Be it known that I, OSCAR, E. HILDEBRAND, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Beading-Tools, which improvements are fully set forth and described in the following specification, reference being had to the accompanying drawings, in which —

Figure 1 is a side view of said improved tool, and Fig. 2 a top view of the same. In Fig. 3 I have shown a transverse sectional view on line x x of Fig. 2.

My improvements are in that class of tools used commonly by cabinet makers and other wood-workers for grooving, channeling, or beading work, which cannot easily be done by machinery; and my object is to provide a practical tool, which shall be serviceable and strong, yet cheap.

My device is preferably constructed entirely of metal, the several pieces being of such shape I that they may be assembled with but little fitting.

Referring to the drawings, the letters a a’ represent rods, which are semicircular in cross-section and of sufficient length to receive at each end a handle, b, which handle I prefer to make of cast-iron. These handles are cored centrally throughout their length to slip over the two rods a a’, as will be understood by referring to Fig. 3, and are shaped at the irinner ends with flanges c c, which form gages to guide and control the movement of the knife when in use.

My cutting-tool proper is punched or otherwise formed from steel, and a single blank may have, if desired, several cutters of different designs on its opposite edges, as shown at d in Fig. 1. The cutter thus formed is entered between the flat sides of rods a a’, and the handles b are then adjusted to form the bead at the desired distance from the edge of the board, the depth of the cut being determined by the distance which the cutter projects below the rods. In order to clamp the parts thus adjusted firmly together, I have drilled and tapped the handles to receive clamping-screws e e, which, when screwed home, clamp the parts as rigidly as if they were integral with each other.

By forming my entire tool of metal, I find that the weight thus gained gives an impetus to the tool, which is desirable rather than objectionable, inasmuch as it requires less effort on the part of the operator. In many cases the thumb-screws e e may be dispensed with, the handles being forced onto rods a a’, which action squeezes the rods together sufficiently to hold the cutter; but as a rule I prefer to use clamping-screws, as shown.

Having described my invention, I claim —

1. In a beading-tool, in combination with two companion rods, a cutter adapted to be clamped between said rods, as described, and handles cored to slip over said rods to clamp the said cutters, all being substantially as herein specified.

2. In combination with two semicircular rods, a cutter adapted to be clamped between said rods, and handles cored to slip over said rods, as described, said handles being provided with clamping-screws, by which the several elements may be clamped together, for the purpose specified.

3. In combination with two companion rods, a cutter adapted to be clamped between said rods, as described, handles cored to slip over the ends of said rods and formed with gage-flanges at their inner ends, and thumb-screws or similar means for clamping the several parts together, substantially as herein set forth, and for the purpose specified.

To all whom it may concern:

Be it known that I, WILLIAM HENRY BUSWELL, a citizen of the United States, residing at Manson, in the county of Calhoun and State of Iowa, have invented certain new and useful Improvements in Rabbet-Planes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a top view. Fig. 2 is an end view. Fig. 3 is a detail, and is a vertical section through one of the cast-metal plates.

My invention relates to rabbet-planes designed for use in making rabbets of any desired depth and width in the material to be worked, without previously having to gage the rabbet or use a bevel-square; and the invention consists in the construction and novel combination of parts, as hereinafter described, and pointed out in the claim.

Referring by letter to the accompanying drawings, A designates the stock of the plane, which is provided with the bit-iron B, held in the stock by the wedge C, and the stock may be with or without a handle, according to the kind of plane-stock used. At its ends the stock A of the plane is provided with the cast-metal plates D and E, which plates are provided with longitudinal parallel slots F G, near their upper and lower edges, said slots extending nearly from end to end of said plates, the plates being beveled on their rear faces along the edges of the slots to form elongated countersinks, in which fit the heads H on the screw-stems I.

J J’ are rectangular plates secured to the enter faces of the slotted plates D E, said plates J J ‘ being held to their adjustments on the outer faces of the slotted plates D E by the screws I and thumb-nuts K K’.

L L’ are pivoted plates, secured to the rectangular sliding plates J J ’ by pivots M, passed through their lower inner corners. The pivoted plates L L’ are provided with arc slots N, in their cam-shape portions O, and from these cam-shape portions O project integral arms P, between which the gage-bar Q is secured by screws R R’, passed through holes in the arms P into the ends of the gage-bar Q.

By loosening the thumb-nuts K K’ the gage-bar can be moved in or out as far as the parallel slots will permit the slotted rectangular plates to slide.

By loosening the thumb nuts V V’ on the screws Y Y’, passed through the arc slots N, the gage-bar Q may be turned on its pivots, and be thereby caused to assume the required angle, after which the thumb-nuts V V’ may be tightened to hold the gage-bar at the angles to which it has been adjusted while the plane is being used. The upper edge of the gage-bar is beveled to fit the bottom of the plane and hold the gage-bar at the proper angle when said edge is moved under the stock of the plane.

Having described this invention, what I claim, and desire to secure by Letters Patent, is–

The improved rabbet-plane described, consisting of the stock A, the plates D E, having ing the parallel longitudinal slots and secured to the opposite ends of the stock in a plane relatively at right angles to the face thereof, the sliding rectangular plates J, held in sliding engagement with the said end plates by the transverse screws and nuts I K, the gage-bar, the plates R, having a semicircular slot, the thumb-nut working therein, an arm, P, for attachment to the ends of the said gage-bar, and their lower inner portions pivoted to a like point of the sliding end plates, substantially as specified.

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

To all whom it may concern:

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

My invention relates to improvements in bench-planes, and has particular reference to mechanism for adjusting the cutter.

The object of my invention is to provide a simple, convenient, and inexpensive mechanism for this purpose.

In the accompanying drawings, Figure 1 is a perspective view of a bench-plane showing my adjusting mechanism, and Fig. 2 is in part a longitudinal section through the adjusting mechanism and in part an elevation.

The plane in its general feature is of ordinary construction, of which a designates the cutting-bit-, b the cap-iron, and A the holding cap or clamp for holding the cutter in place. I pivot an angle-lever, c, in the body of the holding cap A, with one arm of said lever projecting through the holding-cap into a hole made to receive it in the cap-iron b in case of a plane having a double iron, or in the cutter itself or some part rigidly affixed thereto in case of a plane having a single iron. The outer end of the lever, as shown, has two arms, d d, which constitute the operating-handles for moving the lever to adjust the cutter up or down. These two handles are a convenience, as by pressing upon one of them the cutter is forced downward, while pressing upon the other forces the cutter upward. Only one arm, however, is necessary, as that will operate to adjust the cutter both ways by pulling outward or depressing said arm.

The main feature of my invention resides in the adjusting-lever pivoted to the holding-cap, and having a handle which forms a part of said lever upon the upper front side of said holding-cap.

I am aware that it is old to employ a lever having one arm connected with the cutter, while the other arm serves as an operating-handle of a plane-bit-adjusting mechanism, said lever being pivoted to the stock underneath and back of the cutting-bit, and the same is hereby disclaimed. Such an adjusting-lever can only be reached by the ends of one’s fingers, and is very inconvenient to operate, besides being in the way when grasping the handle of the plane. By my invention all the space under the frog and in front of the handle is left open and unobstructed, so that there is plenty of room for the fingers of the operator while grasping the handle, and no liability of hitting and hurting the fingers, as there is in planes having this space cramped by an adjusting mechanism. The construction is also very much simplified, so that the plane can be produced at a small cost. It also enables me to use a T form of lever when desired, so that the cutter can be adjusted both up and down by covering the two arms d d with the palm of one’s hand and bearing down upon either arm. Such a mode of adjusting cannot be employed when the adjusting-lever is placed back of and underneath the cutting-bit. Even with only one arm for an operating-handle, the lever is much more accessible and more conveniently operated than in any prior plane known to me.

I am also aware that an adjusting mechanism for a plane iron is shown in a prior patent as provided with an operating-screw for the adjusting mechanism, the handle of which screw is upon the upper front side of the holding cap or clamp, and I hereby disclaim the same.

I claim as my invention —

1. In a bench plane, the combination of the cutting-bit a, the holding cap or clamp A, and the adjusting-lever pivoted thereto and having its operating-handle on the upper front side of said holding cap or clamp, substantially as described, and for the purpose specified.

2. In a bench-plane, the adjusting angle-lever c, having one arm for connecting with the cutting-bit projected through the holding cap or clamp A and pivoted thereto, and the two arms d d, extending in opposite directions from the main arm upon the upper front side of the cap, to serve as operating-handles, substantially as described, and for the purpose specified.

_________________

To all whom it may concern:

Be it known that I, JOHN L. DE HUFF, of Reading, in the connty of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Router-Planes, of which the following is a specification.

My invention relates to planes used by pattern or cabinet makers, and particularly to what are known as “router-planes,” employed for grooving or channelling wood-work.

It is the object of my invention to construct a device of the character mentioned which shall be more serviceable than those heretofore employed, in that it will not be liable to become clogged or obstructed in its operations by shavings, may be readily adjusted to tools or plane-irons of different forms and sizes, and may have other points of advantage, all as hereinafter fully described, and subsequently pointed out in the claims.

In the drawings hereto annexed and forming a part of this specification, Figure 1 represents a top plan view of my improved router-plane, one handle being shown as removed; Fig. 2, a front view; Fig. 3, a vertical section on the line x x, Fig. 2; Fig. 4, a section on the line y y, Fig. 2; and Fig. 5, an end view.

Similar letters of reference indicate similar parts in all of the figures.

In the drawings, a represents the stock of the plane, b, the sole thereof, c, the handles, and d the cutting-tool or plane-iron. As shown, the sole is formed in two equal sections, adjustable longitudinally on the stock by means of a screw-threaded stem or stud, e, secured to the upper surface of each sole-section a, which stem or stud projects through an elongated slot, f, in the stock, and upon which the handles are secured by being screwed thereon, as clearly represented in Figs. 3 and 5. A washer is preferably interposed between the base of the handle and the upper surface of the stock. By the construction described the stem or stud e serves the purpose of attaching the handle to the stock, and, inconnection with the handle, of clamping the sole-sections b to the stock proper at any point thereon within the limit of its adjustment, and an open channel, c*, from front to rear of the plane, is formed between the sole-sections. Each sole-section is provided on its upper surlhce with ribs g, extending along the sides thereof, as shown in Figs. 1 and 5, and the under surface of the stock proper, at both sides of its center, is provided with ribs h h’, the sides of which ribs are adapted to slide in correspondingly shaped grooves formed in the ribs g on the sole. (See Fig. 4.) Rib h’ on the under surface of the stock is constructed to move between the ribs g to form a close joint or connection between the stock and sole, and thus avoid liability of shavings becoming caught between the parts and obstructing the operations of the device. Any other construction and arrangement of ribs g and h to answer the same purpose would be within the scope of my invention.

The stock is cast or otherwise formed with a chamber, i, at its center, and with lugs j j projecting laterally from above and below said chambered part. Holes k and l are bored through the upper and lower portion of the chambered portion, and rod m, fitted to turn in holes k, is extended therethrough, as clearly shown in Fig. 4. Said rod is screw-threaded on that portion passing through the chamber, and is so stepped in the lower portion of the stock proper as to turn or rotate in holes k, but not to move vertically therein, a head, n, being secured to the upper end of said rod, whereby it maybe rotated. The holes l in the lugs j are adapted to receive the stem o of the plane-iron or cutting-tool. The screw-threaded portion of the rod in passes through a corresponding screw-threaded hole in a traveler, p, within chamber i, whereby by turning said rod said traveler may be raised or lowered thereon within said chamber. Said traveler is provided with a split clamp-extension q, through which the stem of the plane-iron is adapted to pass, and in which it is adapted to be clamped or secured by means of a bolt passing through ears r of said split clamp portion.

It will now be understood that a cutting tool or iron of any character may be secured in the clamp of the traveler at any horizontal angle therein, and adjusted by means of the rod on to any desired height, while the sole parts b b of the stock can be adjusted to a position as close to or far from the tool as the size or form of the cutting portion of the planer-iron may require.

Experience has demonstrated that a router-plane constructed in accordance with my invention is serviceable in the highest degree in all the uses for which a tool of that character is designed, and that there is no liability of the device becoming clogged or obstructed in its operation by shavings or chips cut from the material being operated upon. The edges of the soles are given a sloping form, and a gage, s, grooved to fit said edges, is secured thereon by means of thumb-screws t, as shown in the drawings. This gage is adapted to operate against the edge of the material being grooved or channeled, by which means the groove may lie formed in different pieces, the material at precisely the same distance from the edge, all as will be readily understood by those skilled in the art.

I do not confine myself or expect to be confined to the precise form and arrangement of parts shown and described, as these may be changed without departing from the spirit of the invention.

What I claim is —

1. A router-plane having its sole portion formed in two parts, one or both of said parts being adjustable longitudinally on the stock to and from the side or sides of the planer-iron or cutting-tool, as set forth.

2. A router-plane provided with a planer-iron or cutting-tool adjustable vertically therein, and having its sole portion formed in two parts longitudinally adjustable on both sides of the planer-iron or cutting-tool, as set forth.

3.

To all whom it may concern:

Be it known that I, AMOS FALES, residing in Rockfall, in the county of Middlesex and State of Connecticut, have invented Improvements in Variable Bench-Planes; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

Figure 1 is a view in perspective of the main stock of the instrument as provided with my improved means of applying the fillister and grooving attachments with reversible and adjustable fence; Fig. 2, a front end view of the same; Fig. 3, a side view of one of the attaching-brackets; Fig. 4, a top view of the same; Fig. 5, a front end view of the instrument having its fence reversed for making a front fillister; Fig. 6, a front view of a set of dado-spurs of different sizes; Fig. 7, a side view of one of the spurs; Fig. 8, a side view of the main stock, with a pair of form-plates attached thereto, showing the manner in which the dado-spurs are applied; Fig. 9, a bottom view of the same; Fig. 10, a front view of a spur having only one cutting-point; Fig. 11, a side view of the main stock provided with thin removable extension-flanges for cutting extremely-narrow grooves; Fig. 12, a bottom view of the same; Fig. 13, a front end view of the same; Fig. 14, a side view of the front form-plate constructed to be adjustable lengthwise; Fig. 15, aside view of a special form of cutter used; Fig. 16, an end view of the same; Fig. 17, a top view of a cutter provided with a cap-iron attached thereto; Fig. 18, a side edge view of the same; Fig. 19, a bottom view of the same; Fig. 20, a front view of forward form-plate having a dado-spur.

Like letters designate corresponding parts in all of the figures.

The general construction of the bench-plane on which the present improvements are based is shown and described in the previous patents granted to me March 7, 1882, and April 1, 1884, and numbered, respectively, 254,542 and 295,916. Especially I will refer to one or the other of those patents for the construction of the main stock A, with its flange a, for attaching other parts of the instrument thereto, and means for securing the cutters B therein, the front and back form-plates, C D, and the reversible fence E.

Referring to those former patents, it will be noted that the front and back form-plates are attached to the downwardly-projecting stock-flange a, each by means of a single set-screw, b, fitting in a vertical notch or slot, c, of the form-plate flange d.

The first improvement herein to be described consists in the means whereby grooving and filiister attachments are applied, as shown in Figs. 1, 2, 3, 4, and 5. Two brackets, G G, are employed, constructed substantially as shown — that is, each with a vertical flange, e, having a vertical notch or slot, f, whereby it is attached to the flange a of the stock by one of the set-screws b b, used for attaching the form-plates, which are dispensed with for the special purposes of this device, and each having a horizontal flange, g, with a notch or slot, h, at right angles to the stock-flange, for attaching the reversible fence E by screws i i. The upper edges or terminations, e e e, of each bracket are in one horizontal line, in order to fit against the overhanging ledge k of the stock and serve as a guide or gage for placing the bracket in a correct position without care. Thus this entire appendage is attached to the main stock by the same means as the form-plates used for other kinds of work. Fig. 2 shows how the fence thus attached by these brackets is used for grooving.

Fig. 5 shows the fence reversed and provided with an overhanging ledge, l, for forming a front fillister. Here the ledge, being in line with the lower edge of the stock-flange a, serves for form-plates, which, for this purpose, therefore, are dispensed with. The ledge l is cut away in the middle, so not as to be in the way of the cutter, and not to interfere with the discharge of the shavings. The fence being adjustable laterally allows the grooves to be cut at any desired distance from the front edge of the material, and by employing two stocks — one arranged for grooving and the other for tonguing — no changing from one to the other kind of work is necessary for tonguing and grooving. The vertical flange of each bracket is of such height that when placed in contact with the overhanging ledge k of the main stock the grooves will be cut to the regular or greatest depth required, the distance from the lower surface of the bracket to the lower edge of the stock-flange determining the depth of cut, since the brackets serve as gages to limit the depth of cut. When a shallower cut is desired, the brackets may be adjusted farther down on the stock-flange, both brackets alike, thus obviously effecting the purpose.

Fig. 6 of the drawings shows a front view of a set of dado-spurs of different widths, and Fig. 7 a side view of either one of the spurs. Each spur H is a double spur, having two cutting-points, m m, cutting at both edges of the work cut by the cutter used, whether for dado, fillister, bead, or other form of cutting. Between the cutting-points m m is a space, n, of sufficient depth to admit the form cut, of whatever shape. Each spur has a vertical (preferably round) stem, o, which is inserted in a vertical hole in the plane-stock. Each spur, in combination with a cutter and main-stock flange, is a complete dado. The stem o of each spur is always at the same distance from one extremity and spur, whatever the distance of the other spur from the first spur, so that the various widths of spurs always bear the same relative and proper position on the stock, and all the spurs are attached by the same means.

The means of attaching each spur is shown in Figs. 8 and 9. The round stem o of the spur is inserted in a vertical hole through the main stock; A and its flange a, and the body p of the spur has parallel faces or front and back sides, which fit against the sides of a notch, q, in one of the form-plates, which lap over the lower edge of the stock-flange, so that the spur is readily adjusted up and down, and yet is held iirmly and accurately in position without turning out of line. The spur is retained in place by a set-screw, r, screwed into the side of the stock. The same general construction and means of attaching the spur apply when it only has one cutting-point, as shown in Fig. 10, and at the right hand in Fig. 6. The spurs are located in advance of the side and center cutters, as shown in Figs. 8 and 9, the front form-plate, C, being notched to receive the spur used a little in advance of the position of the cutter in the main stock, substantially as shown. By this construction cross-grained and curly wood is smoothly cut, the spur-point leading the cutter-edges of the cutter.

Another improvement in my present invention consists in the means by which extremely narrow grooves may be cut with the instrument. Since the main-stock flange is required to be three-sixteenths of an inch thick, or thereabout, in order to give it suflicient strength with this alone, no groove less than three-sixteenths of an inch wide can be cut therewith. For the purpose of cutting narrower grooves, which are often required or very desirable, I employ extension-flanges I J, front and back, as shown in Figs. 11, 12, and 13. These flanges are made of steel and as thin as required. They extend below the main-stock flange a sufficiently to cut the requisite depth below the same, as shown in Fig. 13. Each extension-flange is secured to the front side of the main-stock flange and reaches up to the overhanging ledge k of the main stock, and is attached to the flange by a single set-screw, b, the same as for attaching the form-plates when used. Thus no change in or addition to the usual construction of the plane is required, except as to the extension-flanges themselves, which are cheaply made. A correspondiugly-narrow dado-spur, H, is combined with the front extension-flange, as shown in Figs. 11 and 12. This spur is held in a shallow vertical groove in the front side of the flange, and held there by a set-screw, s. The spur is slotted vertically where held by the screw for the purpose of adjustment. A similar way of attaching a spur to the front form-plate is shown in Fig. 20, the spur being reversible and cutting-edges different. By the above construction a groove not exceeding one-sixteenth of an inch in width may be readily cut, and a double-point spur used to make smooth sides, and a series of narrow grooves from that width up to three-sixteenths is easily made by using spurs and cutters of the various widths required. These extension-flanges can be used with the grooving and fillister attachments above described, or with the auxiliary stocks described in my former patents above mentioned.

Another point of improvement consists in the adjustable mouth for the cutter, so that a wide mouth may be had, when required, or a narrow mouth for cutting the finest shaving without any liability of the front form-plate coming in contact with the edge of the cutter. The mouth is made adjustable simply by means of the front form-plate, C, being made with its attaching notch or slot widened where the attaching-screw passes through it, as shown at t in Figs. 8 and 14. This widening is but little, since the entire adjustment required is quite limited in extent. The head of the attaching-screw will cover the sides of the notch or slot in any position of its adjustment. There is a V-shaped groove, u, or of a form conforming to the shape of the cutter itself, in the front side of the cutter, as shown, forming thereby overhanging cutting-edges v v on both sides of the groove. By this construction the edges overcut, instead of undercutting in the wood, as does the ordinary cutter, so that there is no tendency to raise or tear up the fibers of the wood. With this improved construction of the cutter cross-grained wood may be grooved, and any wood grooved across the grain as smoothly as when the cutter cuts with the grain of the wood. The construction of this cutter will be made the subject-matter of a design patent, it being represented in this application in order to show its mode of application. The cap-iron K is shown as short, only covering a little of the lower end of the cutter B, so that the main part of the cutter is not incumbered therewith, and its body fits in the stock with the cap-iron, the same as if the cap-iron were not there, one form of stock, therefore, serving for such cutters as well as for all other forms of cutters used. The cap-iron is attached by a set-screw, w, passing through a slot, x, in the cutter, as shown in Fig. 19. Thereby the cap-iron is made adjustable to the edge of the cutter. This cap-iron may be applied to dado, flllister, hollow, and round cutters.

I disclaim in this invention form plates or extensions attached to the main flange, such as set forth in Letters Patent No. 295,916, granted to me April 1, 1884, wherein such extensions project at right angles to the main-stock flange, and do not and cannot extend below the said stock-flange.

I claim as my invention —

1. The combination of the stock A, the fence E, and the brackets G G, the said brackets being provided with vertical and vertically-slotted flanges e e, whereby they are adjustably attached to the stock, and with horizontal flanges g g, having slots at right angles to the stock, whereby the fence is attached in position adjustable toward and from the stock, substantially as and for the purpose herein specified.

2. In combination with the stock A and its main attaching-flange a, the vertical plane extension-flanges I J, attached to the side of the main flange, and extending directly downward therefrom and below the same, whereby very narrow grooves may be cut in the material, less in width than the thickness of the said main flange, substantially as herein set forth.

3. The combination of the stock A, having a main attaching-flange, a, a front vertical plane extension-flange, I, removably attached to the said main flange, extending directly downward from and below the lower edge of the said main flange, and provided with a double spur, H, and the rear vertical plane extension-flange, J, removably attached to the main flange and extending directly downward from and below the lower edge thereof, substantially as and for the purpose herein specified.

4. The combination of the stock A, having a flange, a, and front form-plate, G, having an attaching-slot, c, widened from front to back, whereby the said form-plate may be adjusted forward or backward by the attaching-screw b, substantially as and for the purpose herein specified.

Application filed November 14, 1885. Serial No. 182,808. (No model.)

_________________

To all whom it may concern:

Be it known that I, WILLIAM GALWAY STRANAHAN, of Minneapolis, in the county of Hennepin, State of Minnesota, have invented a certain new and useful Blind-Nailing Plane, of which the following is a full, clear, and exact description.

Prior to my invention, in blind-nailing it has been customary to use a chisel formed with two lips, in order to take up a small shaving from the surface of the wood, which shaving, after the introduction and driving of the nail, was returned to place and glued to the body of the wood; but not only was this a very slow way of doing the work, but the shaving was apt to be crumpled and narrowed, so that it did not fully fill up the cut, and the spot was liable to show.

With my improved form of instrument I am able to quickly form the shaving without in any way crumpling or narrowing it, so that when the nail has been driven the shaving may be returned to its original position, to be glued in place, and will entirely fill up the cut, so that after the operation is completed and the surplus glue removed it is impossible to locate the point where the nail has been driven.

The invention consists of a plane provided with a shuttle which carries a narrow knife, said shuttle being operated by a hand-lever, and the parts so arranged that the knife will project slightly through a longitudinal groove formed in the body of the plane, to strike against and out beneath the surface of the wood that is to be operated upon.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal vertical sectional view of my blind-nailing plane. Fig. 2 is a vertical cross-sectional view taken on line x x of Fig. 1. Fig. 3 is a view of the bottom of the plane. Fig. 4: is a view of a modified form of construction.

My preferred form of construction is illustrated in Figs. 1, 2, and 3, wherein A represents the plane-body, the bottom of which is formed with a narrow longitudinal groove, a. The side walls, b b, project upward from either end of the plane, and are each formed with a curved slot or way, c, said ways being parallel with the bottom of the plane until they reach a point, e, when they are curved upward and backward.

Between the walls b b there is arranged a shuttle, D, formed with a throat, f, and a knife-seat, f’, to which knife-seat the blade or knife h is secured by a set-screw, h’, the knife being, as usual , slotted to admit of proper adjustment.

Upon each side of the shuttle D there are two round lugs, d d, which fit within the curved ways or slots c, and upon the upper side of the rear end of the shuttle there is a nose-piece, k, formed with aslot, k’, within which the horizontal pins o of the lever F rest. This lever F is pivotally connected between the walls b b in substantially the position shown in Fig. 1, and is provided with a rearwardly-extending arm, C.

The shuttle D is provided with a projection, l, which fits closely within the slot a, the knife k being also formed to fit snugly between the side walls of said slot, but still to be capable of being moved between said walls. A wire spring, K, both ends of which are fixed to a pin, m, extends backward therefrom and is looped to embrace the pivotal point n of the lever F, from which point there is a stirrup-like loop, which passes back of the lever and below its manipulating-arm, so that when the lever is depressed the action of the spring will restore it to its normal position after the pressure is relaxed. Within a recess formed in the leading end of the plane, in front of the slot a, I secure a block of rubber, as shown at H, and upon the upper side of the forward end I affix a knob, N.

In the construction illustrated in Fig. 4 the shuttle shown as being formed with a toothed rack, p, and the lever F as being provided with a toothed segment, p’, which engages with the toothed rack of the shuttle.

The operation is as follows: The lower side of the plane is applied to the board or block which is to be nailed into place and pressed firmly against such board or block, a secure hold being obtained upon the knob N and the plane being prevented from slipping by the rubber block H. The manipulating-arm C is then pressed downward, and being so pressed will carry the lever F downward and forward, so that the knife h. will strike against the surface of the board or block and cut a thin shaving therefrom, which shaving will pass up through the throat f; but as the way c is parallel with the bottom of the plane the shaving will not be detached from the board, and as the lever-arm C is released it will be returned to the position shown in Fig. 1 by the action of the spring K; and as the knife k and the projection l of the shuttle D fit closely within the groove A the edges of the shaving will not be torn, nor will it be crumpled so as to be narrowed, and consequently, after the nail has been driven in the cut formed by the knife h, the shaving, when returned to place and glued within the cut, will completely fill it, and it will be almost impossible to discover where the cut was made. The upward motion of the lever F is limited by the pin i.

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

1. The combination, with a plane-body formed with a longitudinal slot, a, of a shuttle carrying a knife, and an operating-lever, the shuttle working in the body with its knife extending into the slot a, substantially as described.

2. The combination, with a plane-body formed with a longitudinal slot, a, and side slots, c c, curved upward at their rear ends, of a shuttle carrying a knife and formed with lugs d d, working in the slots c c, and an operating-lever for reciprocating the knife in the slot a, substantially as described.

3. The combination, with a plane-body formed with a longitudinal slot, a, and side slots, c c, curved upward at their rear ends, of a shuttle carrying a knife and formed with lugs d d, an operating-lever, and a spring, substantially as described.

4. A blind-nailing plane in which the following elements are combined: a plane-body, A, formed with slot a and side slots, c c, curved upward at their rear ends, shuttle D, formed with lugs d d and a slot, k’, a knife, h, secured to the shuttle, a lever, F, manipulating-arrn C, and a spring, K, substantially as described.

5. A blind-nailing plane formed with a longitudinal groove, a, and side grooves, c c, a shuttle, D, formed with lugs d d and carrying a knife, as h, a lever, F, arm C, and block H, substantially as described.

SPECIFICATION forming part of Letters Patent No. 345,278, dated July 13, 1886.
Application filed March 17, 1886. Serial No. 195,610. (No model.)

_________________

To all whom it may concern:

Be it known that I, CHARLES HENRY SLICER COLLINS, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and useful Improvement in Core-Box Planes, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to an improvement in core-box planes; and it consists in the peculiar construction and combination of devices, that will be morefully set forth hereinafter, and particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my invention, partly in section. Fig. 2 is a front elevation of the same, showing the plane in operative position for planing a semi-cylindrical surface in a core-box. Fig. 3 is a detailed end elevation of the frame. Fig. 4: is a detail sectional view of the same, taken on the line x x of Fig. 1.

A represents the frame of the plane, which is composed of the metallic plates B, secured together at one edge and extending at right angles from each other. The plates B are connected at their front and rear ends by brace-plates C. In the angle formed by the two plates B, near the rear end of the same, is secured a handle, D, and in the angle formed by the two plates and near the front ends thereof is secured a projecting stud or standard, E, for the operator to take hold of with his left hand, his right hand grasping the handle D.

E’ represents a block, which is located in the angle formed by the plates B, and extends vertically midway between said plates. The front side of this block is inclined at an angle of about forty-five degrees, and is provided on opposite sides of the web of the block with flanges e, forming a broad bearing-face for the bit F, the point of which is beveled on opposite sides, as shown in Fig. 2, and extends through an opening, G, made between the converging edges of the plates B, in rear of the standard E.

H represents a clamp, which is provided with depending arms having inwardly-projecting studs that engage the under sides of the flanges e of the block E’, the said clamp having a spring, i, which bears on the upper side of the plane-bit, and provided with a thumb-latch, K, which is pivoted in the rear end of the clamp H and bears against the outer end of the spring. By this construction it will be readily understood that the plane-bit may be secured to the frame A at any desired adjustment, and moved in or out through the opening G in the said frame.

In Fig. 3, L represents extension-plates which are provided on one edge with extended arms M, through which arms pass screws N, that work in threaded openings O, made near the upper edges of the plates B, whereby the said extension-plates L may be secured to the outer edges of the plate B, or removed therefrom. By thus providing the extension-plates for the side plates of the frame of the plane, the latter is adapted for planing semi-cylindrical openings or grooves of any desired diameter.

The operation of the plane will be readily understood from an inspection of Fig. 2 and the foregoing description. The groove in the core-box a is first roughly gouged out, as shown, and the radius of the groove is drawn at each end of the core-box, as represented by the dotted lines c in said Fig. 2.

Having thus described my invention, I claim —

l. The combination of the frame having the rigid sides B, arranged at right angles to each ether, connecting by rigid brace-plates C, and the planing-bit projecting through an opening in the converging edges of the sides, and the extension-plates L, extending out at the same angle as the sides B, and means for securing the said plates to the outer edges of the sides, for the purpose set forth, substantially as described.

2. In a core-box plane, the frame comprising the rigid sides B, arranged at right angles to each other, the rigid plates C, connecting the sides at the ends, and the extension-plates L, secured to the outer edges of the sides B, and extending upward at the same angle as the sides, for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
