To all whom it may concern:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

To all whom it may concern:

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

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

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

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

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

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

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

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

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

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

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

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

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

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

SPECIFICATION forming part of Letters Patent No. 538,937, dated May 7, 1895.
Application filed August 9, 1894. Serial No. 519,912. (No model.)

_________________

To all whom it may concern:

Be it known that I, JACOB W. TRIPP, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved Combination-Plane, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved plane, which is comparatively simple and durable in construction, arranged for universal adjustment to enable the operator to conveniently plane straight or curved work, such as stair rails, on all sides, and for molding, fitting, plowing, tonguing and grooving, rabbeting and other purposes, also to form beads, fillets, &c.

The invention consists principally of a stock adapted to receive a removable wooden sole piece shaped to conform to the curved or straight surface to be planed.

The invention further consists in a bit having gear teeth adapted to be engaged by a segmental lever, for shifting the said bit into proper position.

The invention also consists in an auxiliary guide stock pivoted on an adjustable arm held on the main stock.

The invention also consists in certain parts and details, and combinations of the same, as will be fully described hereinafter, and then pointed out 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 views.

Figure 1 is a side elevation of the improvement. Fig. 2 is a plan view of the same. Fig. 3 is a sectional side elevation of the improvement on the line 3 3 of Fig. 2. Fig. 4 is an enlarged transverse section of the bit-guide, the section being taken on the line 4 4 of Fig. 3. Fig. 5 is a transverse section of the improvement on the line 5 5 of Fig. 1. Fig. 6 is a sectional rear elevation of part of the improvement on the line 6 6 of Fig. 5. Fig. 7 is a side elevation of the improvement, showing a modified form of sole-piece. Fig. 8 is a perspective view of a modified form of guide-piece for the auxiliary guide-stock. Fig. 9 is a perspective view of a modified form of sole-piece in front of the cutting-bit. Fig. 10 is a sectional plan view of part of the improvement on the line 10 10 of Fig. 7. Fig. 11 is a rear elevation of the auxiliary guide and adjacent parts. Fig. 12 is a side elevation of the improvement arranged with a straight wooden sole-piece, part of which is broken out. Fig. 13 is a sectional plan view of the same on the line 13 13 of Fig. 12. Fig. 14 is an inverted plan view of the bit. Fig. 15 is a plan view of the same. Fig. 16 is a face view of a combination quick cutter and blank. Fig. 17 is a face view of a modified form of fastening for the quick cutter, and Fig. 18 is a sectional plan view of the same on the line 18 18 of Fig. 17.

The improved plane is provided with the metallic stock A, having an integral handle A’, and a bit plate A2 extending in an inclined direction, as plainly shown in Figs. 1 and 3, and fastened by screws or other means to the stock A and handle A’. On the under side of the stock A, is adapted to be secured by screws orother means, a sole piece B, having its bottom made in various shapes according to the article to be planed. The sole piece is made of wood, and is shaped at its under side to correspond to the shape of the article to be planed, as will be readily understood by reference to Fig. 1, or is made straight at its under side for planing straight surfaces of different shapes, as illustrated in Fig. 12.

On the lower end of the cap C is secured a sole piece B’, forming a continuation of the sole piece B, and shaped according to the article under treatment, that is, either curved at the under side, as shown in Fig. 1, or straight as illustrated in Figs. 9 and 12. The pressure plate or cap C for the plane, is adapted to engage and hold the cutting bit D on the bit plate A2.

In order to shift the bit D, I form the top surface thereof at the upper end with rack teeth D’ adapted to be engaged by the teeth E’ of a segmental lever E, formed with a slot E2 adapted to engage a pin C’ extending transversely in the pressure plate C, and through an aperture C2 therein, as will be readily understood by reference to Fig. 3. Now when the pressure plate C is in place, the operator inserts the segmental lever E in the aperture C2, so that the pin C’ forms a fulcrum for the said lever, and the teeth E’ of the latter engage the rack teeth D’ of the bit D. When the operator swings the lever E either up or down, then the teeth E’ shift the bit D down or up, so as to adjust the cutting edge of the bit according to the under side of the sole piece B. After proper adjustment is made of the bit D, then the segmental lever E is again removed from the aperture C2 and the pin C’. The pressure plate or cap C is held from sliding by dowels F, F’, which project at right angles from the bit plate A2. See Fig. 3. To clamp the bit in place on the bit plate A2, I provide a screw rod F2, secured in the bit plate A2, parallel to the dowels F F’. The screw rod F2 is provided with the smooth piece F3, extending through the bit slot D2 and the cap C. The reduced end F4 of the screw rod F2 engages a removable block G, fitting under the head F5 of the said screw rod, and on the sides of the said block G is fulcrumed a cam lever G’, formed near its outer end with an opening G2 adapted to fit over the outer end of the dowel pin F’, whenever the said cam lever is in a closed position, as shown in Figs. 1, 3, and 12. The cam is formed on the fulcrumed end of the lever G’, and engages a wearing plate G4 held on the pressure plate C, so that when the lever G’ is swung inward, then the cam portion of the said lever presses on the wearing plate G4, to raise the block G, and to securely press the latter against the under side of the head F5 of the screw rod F2, whereby the pressure plate C is firmly pressed inward onto the bit D, to clamp the latter securely in position. The wearing plate G4 can be dispensed with in case the cap C is made of a hard material.

When the lever G’ is swung outward into the position shown in dotted lines in Fig. 3, then the cam end of the lever releases the block G from pressing on the head F5, thereby loosening the pressure plate C sufliciently to remove the cutting bit D as may be desired. In order to properly guide the bit D, I provide the under side thereof with a longitudinal recess D3, see Figs. 3 and 14, engaged by a lug A3 formed or secured on the bit plate A2.

On the lower end of the cap C, and abutting on the face of the bit D, is arranged an adjustable plate C4, formed with a longitudinally-extending shoulder C5 fitting into a correspondingly shaped groove in the cap or pressure plate C, as plainly shown in Fig. 4. A screw C6 serves to hold the adjustable plate C4 in place on the pressure plate C, the said screw passing through a longitudinally-extending slot C7 formed in the adjustable plate C4. By the arrangement described, the plate C4 can be readily adjusted on the pressure plate C, by loosening the screw C6, and then shifting the said adjustable plate C4 so that its lower end is as close down to the cutting edge of the bit as desirable, to permit of cutting in cross-grained wood without danger of tearing it or leaving a rough surface.

On the rear face of the stock A, is held adjustably a block H, provided with an obliquely-extending slot H’, through which passes a screw H2 screwing in the stock A, as teaser indicated in Figs. 6 and 7. A shoulder H4, see Fig. 10, formed on the back of this block H engages a correspondingly shaped groove A5 in the rear face of the bit plate A2, the said groove A5 being arranged parallel or in alignment with the slot H’, so as to permit of shifting the block H in an oblique direction on the stock, as required. On the back of the block H is formed a vertical recess or groove H3 (see Figs. 2 and 5), in which is held adjustable a quick cutter or bit I, for cutting the sides or edges of the wood under treatment, as plainly illustrated in Figs. 5 and 7. The quick cutter I, may be held in place on the block H, either by a screw I’, as shown in Fig. 5, or by making it dovetailed in cross section and clamping it in position at one edge by a cap H7 adapted to be fastened to the block H by a screw H8, as shown in Figs. 17 and 18. Instead of the cutter or bitI, I may place a blank I3 in the said groove H3, see Fig. 12, and the cutter I and blank I3 may be combined in a single piece, as illustrated in Fig. 16. The blank I3 is provided with a row of apertures, one of which is adapted to be engaged at a time by the set screw I’, but the blank may also be held in place by the cap H7 above mentioned. This blank I3, when used, prevents the shavings from accumulating in the plane throat and choking the plane, and is especially serviceable when cutting deep slots or grooves with the bit D, or other bits that may be used.

On the lower end of the block H is pivoted at J’, the auxiliary guide stock J, extending transversely, as plainly shown in the drawings, and carrying at its lower end an adjustable plate K, engaged by a set-screw K’ passing through a slot J2 extending longitudinally in the auxiliary guide-stock J. By this arrangement the plate K can be adjusted laterally in the guide stock according to the thickness or width of the wood under treatment. The screw K’ is adapted to engage one of a series of apertures K2, K3, K4, in the plate K, so as to increase the range of adjustment of the said plate K on the said guide-stock J.

On the front end of the plate K is arranged a foot-piece K5, made of wood or other suitable material, and shaped to correspond to the shape of the wood to be planed, as indicated in Figs. 5 and 8. The foot-piece K5 shown in Fig. 8 is more especially designed for use on twisted and crooked work. The foot-piece K5 is opposite the front sole-piece B’, secured to the under side of the shavings cup C9, as will be readily understood by reference to the dotted lines in Fig. 1, the said foot-piece also extending rearwardly a suitable distance, so that its rear end is about opposite the cutting edges of the bits D and I.

On one side of the auxiliary guide stock J is fitted to slide transversely, a block L, having a longitudinally extending groove L2 engaged by a set screw L’ screwing in the auxiliary guide-stock J, the screw L’ thus admitting of a right or left movement of the said block, and the screw is adapted to engage one of a series of tap apertures J3 in the auxiliary guide-stock J. See Fig. 11. A link N, pivotally connects this block L with a stud N’ secured on the block H, so that the upward and downward swinging motion of the auxiliary guide-stock is limited, but any desired adjustment can be made by adjusting the screw L’ in one of the series of tap apertures J3 in the auxiliary guide stock J. By this arrangement the auxiliary guide-stock J can be moved in a tilted position according to the wood under treatment, or the main stock A may be inclined, as shown in dotted lines in Fig. 5.

Now it will be seen that with the device described, almost any desired form of molding can be planed as the tool is universall adjustable for all kinds of work of any class desired.

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

1. A plane having its body composed of two separable parts, to wit: a stock and a pressure-plate, in combination with a bit located between said parts, substantially as set forth.

To all whom it may concern:

Be it known that I, Jason W. TRIPP, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented certain new and useful Improvements in Planes, of which the following is a description, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to planes, and more particularly to means for adjusting the bit.

It consists in the various matters hereinafter described and claimed, and is illustrated in the accompanying drawings, in which —

Figure 1 is a plan view of the bit plate illustrating more particularly the mechanism by which the bit is raised and lowered. Fig. 2 is a plan view with pressure cap removed showing lever mechanism in dotted lines. Fig. 3 is a perspective partly in section to show the means for adjusting the bit laterally. Fig. 4 is a detail of the pressure cap. Fig. 5 is a detail of the parts for adjusting the bit laterally; and Fig. 6 is a view of the top of the pressure cap.

In the drawings, A is a bit plate and B the bit. Hitherto it has been customary to provide a thumb screw or something similar thereto by which the bit is adjusted vertically, while the lateral adjustment has been effected by an additional member, in most cases a lever. I propose, however, to so construct the plane that one lever shall serve for both adjustments.

In order to provide a chamber for the necessary mechanism, I cut away a portion of the bit plate to form the part C and in the bottom of this I provide a groove c in which slides the block D, held in any position to which it may be brought by a suitable spring E. This spring may be of many constructions but I prefer to use that shown in the drawings, in which a spring plate is provided with projections e, which engage with teeth e’ on the side of the sliding block. A pin F projects from the sliding block and fits between the lugs m formed upon the bit cap so that when the block is moved it carries with it the bit, this being clamped to the bit cap in the usual manner. Another lug n provided with a recess n’ is formed upon the bit cap, while in the side of the bit plate, I provide one or more recesses o, these recesses being preferably dovetailed in order to more firmly hold the projection s for the purpose hereinafter set forth.

A lever R which projects above the rear portion of the bit when the plane is in position for use, is provided with a slot r fitting over the pin F, while upon its inner end is a projection s. A plate of metal S is fastened to the higher portion of the bit plate to prevent the lever from falling out of place when the bit is removed.

The operation of my device will be readily understood. Normally the projection s its in the recess n’ so that when the lever is moved to one side or the other, the pin F acting as a fulcrum, the edge of the bit will be correspondingly adjusted. To raise and lower the bit, the elongated slot r permits the lever to be drawn back until the projectionsis out of engagement with the recess n’, when the lever is turned to the right, the projection s is caught in one of the recesses o and as this projection then becomes a fulcrum, the sliding plate is moved by swinging the end of the lever. When the bit has been raised or lowered as desired, the lever is returned to its normal position.

While I prefer to employ the construction herein illustrated and described, it is manifest that many modifications may be made without in the least departing from the spirit of my invention.

It will be noticed that the lugs m, m and n, are so disposed that two slots for the reception of the pin F are provided instead of one, as found in planes of ordinary construction. The object of this is to adapt the bit for use with plane beds of different lengths.

Another feature of my invention is the pressure cap. At present, it is customary to provide caps with a hinged cam at their upper ends, these caps bearing upon the plane bit at two points only, viz., along the bottom of the pressure cap and at the point at which the cam touches the bit cap. The difficulty with this construction is that no pressure is exerted upon the main portion of the bit, and the result is that in planing hard wood, a slight spring is allowed that portion of the bit between the two bearing points of the pressure cap, thus permitting a slight vibration of the bit. In my device, however, I provide a plate u cut U-shaped as shown, and having its sides connected at the rear by a plate v of spring steel or other suitable material. To this plate v is attached a block W provided with an opening w for the plane bolt a projecting as usual from the bit plate, said block resting at its forward end upon the ledge u’ of the plate u. Hinged to the sides of the block is a yoke X having cams x adapted to bear upon the ledge u’. It will readily be seen that when the yoke of the pressure cap is raised, thus throwing the cams x up from the ledge u’, the cap may be slipped in position upon the plane, and upon the yoke being lowered, the plate u will be forced down upon the bit cap, its upper side resting against the head of the screw a as a fulcrum, bearing upon it with uniform force on the pressure cap’s entire under surface.

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

1. A plane comprising a bit, a bit plate, a block sliding in said bit plate and connected to the bit, a lever connected to the sliding block, and means whereby said lever may be connected with either the bit or the bit plate; substantially as described.

2. A plane comprising a bit provided with a recess, a bit plate provided with a recess, a block sliding in said bit plate, and connected to the bit, and a lever-connected to the sliding block, said lever being adapted to engage either the bit recess or that formed in the bit plate; substantially as described.

3. A plane comprising a bit provided with a recess, a bit plate provided with a recess, a block sliding in said bit plate, a projection upon said block, a depression upon the bit adapted to receive the projection upon the block, a lever provided with a slot fitting over the projection upon the sliding block, and a projection upon said lever adapted to engage with either the bit recess or the recess formed in the bit plate; substantially as described.

4. A plane comprising a bit, a bit plate, ways in said bit plate, a block sliding in said ways and connected to the bit, a spring bearing against one edge of the block and the adjacent way, a lever connected to the sliding block, and means whereby said lever may be connected with either the bit or the bit plate; substantially as described.

5. A plane comprising a bit, a bit plate, ways in said bit plate, a recess formed in one of said ways, a spring plate in said recess, projections upon said spring plate, a block: sliding in said ways, teeth upon the side of the block adjacent to the spring in the way, a lever connected to the sliding block, and means whereby said lever maybe connected with either the bit or the bit plate; substantially as described.

6. A plane comprising a bit provided with a recess, a bit plate having a chamber C formed therein, a groove in said chamber, a block sliding in said groove, a projection upon said sliding block, a depression upon the bit and adapted to receive the projection upon the block, a recess in one wall of the chamber C, a lever provided with an elongated slot fitting upon the projection on the sliding block, a projection upon the lever adapted to engage either the bit recess or the recess formed in the bit plate, and a plate connecting the walls of the chamber; substantially as described.

7. A pressure cap for planes comprising a plate, an opening in said plate, a block hinged to said plate and provided with an opening for the insertion of the plane bolt, and means for raising the free end of the block against said plane bolt; substantially as described.

8. A pressure cap for planes comprising a U-shaped plate, a ledge connecting the lower portions of the sides of the plate, a spring plate connecting the upper ends of the sides of the plate, a block secured at one end to the spring plate and at the other resting upon the said ledge, an opening in said block for the passage of the plane bolt, a yoke hinged to the block at that end. which rests upon the ledge, and cams upon the yoke at its hinged end; substantially as described.

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