To all whom it may concern:

Be it known that I, HENRI FOUCAULT, a citizen of the United States, residing at Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Carpenters’ Planes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to carpenters’ planes, and the invention consistsin the mechanism and combination substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of aplane containing my improvements and having the central portion thereof broken away and the mechanism sectioned vertically to more fully disclose the construction and arrangement of parts. Fig. 2 is a perspective front elevation of the brake iron and locking mechanism of the bit, and Fig. 3 is a perspective rear elevation of the upper section shown in Fig. 2. Fig. 4 is a perspective elevation of the bit itself. Fig. 5 is a perspective elevation of the adjusting mechanism and support for the bit.

A represents the stock of the plane, and B the bit or plane iron. This iron or bit has a perforation or hole –2– near its top which engages a pin –3– on the threaded nut –4– on the adjusting screw –5– having bearings –6– and –7– on the back of the slotted supporting piece C. This adjusting and supporting piece C has a longitudinal slot through which the pin –3– projects, and the said piece is fastened firmly in the stock and made rigid therewith by means of a screw –9– at its bottom or the equivalent thereof. By turningthe adjusting-screw –5– the nut –4– and pin –3– of course would be caused to travel up or down according as said screw is turned and will carry the bit B in either direction, as may be desired. The bit is therefore fed or withdrawn by this adjusting mechanism and it may be set at any point desired or be in a little less or little deeper cut, as the work may require. Now, having the bit thus supported and adjustable, I provide simple and speedy locking mechanism therefor consisting primarily of the parts D and E. The part D is the usual brake iron, and this brake iron is held in position in the stock by means of a support F which is a separate piece and has sockets –10– at its side which are engaged through the sides of the stock by threaded pins G, the inner extremities of said pins engaging in the sockets –10–. The iron D and the said supporting piece F are then fastened together by means of a screw –12–, Fig. 1, which passes through the vertical slot –13– in the support F and enters a threaded hole in the iron D, a washer –14– being interposed upon which the head of the screw is adapted to bear. The said iron D is therefore held adjustable in the support F and may be placed in higher or lower position with respect to the blade or the bit, as may be desired. In operation, the iron D and the support F are really pivoted upon the pins or trunnions G and hence the bit B is held firmly against its back support at two points as is clearly shown in Fig. 1. Now, in order that the said bit maybe secured and removed with ease and speed and firmly held when in use, I employ the lever E which has a forwardly projecting portion –15– at its bottom at right angles substantially to its handle portion and hinged along its edge to the top of the iron D. Upon the rear and centrally of this handle E, I attach a separate member H which likewise is formed with an inwardly extending portion –17– at its bottom and with a heel –18– which is designed to operate on the principle of a cam in its engagement and effect in locking and holding the bit B. The said part H is rigidly fixed to the handle E and an adjusting screw –20– is threaded through the part E at its bottom and engages against the inner portion –17– of the said part H, so that it may be pressed backward more or less according as more or less pressure is required upon the bit. I might fashion the part E with a heel or cam portion to bear directly against the bit, butI have found that it is desirable to have an adjustment at this point owing to different thicknesses of bits and other changing or varying conditions which render such adjustment of the locking member desirable.

In operation, the bit is locked when the parts are in the position as seen in full lines in Fig. 1, and itis unlocked and may be taken out by simply removing it from the pin –3– when the lever E is moved forward into the position shown in dotted lines Fig. 1. It will of course be observed that since the blade D is pivoted on its support the sharp edge thereof at the bottom will be thrown back against the bit at that point when the lever E is forced against the bit at the top so that the bit is locked at two places and firmly held therein. It may, however, be adjusted by turning the screw –5– notwithstanding the fact that it is locked but usually the adjusting occurs when the lever E is open and it is the work of but an instant to open or close said lever and to remove or replace the bit.

What I claim is–

l. In planes, the plane stock, a pivoted support for the brake iron having sockets in its sides and pins through the sides ofthe stock in said sockets and serving as pivot points, a brake iron adjustably attached to said support, a locking lever for the bit pivoted at the top of said brake iron, and the bit held by said lever, substantially as set forth.

2. A plane stock and a bit supported adjustably therein, a pivoted brake iron and a pivoted locking lever on the top end of said iron having an adjustable cam shaped heel to engage the bit and a set screw to adjust said heel, substantially as set forth.

3. The stock and the bit and a support for the bit at its rear having a pin tlirough which the bit is held, in combination with the brake iron, a pivoted support therefor having trunnions –10– and a slot, and a set screw –12– engaging the brake iron through said slot, whereby said iron is adjusted, and a lever E pivoted to the top of said iron and provided with a heel –15– to bear against the fare of the bit above the pivot point of the brake iron, substantially as set forth.

Witness my hand to the foregoing specification.

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 Planes, of which the following is a specification.

This invention relates to planes; the object of my present invention being to furnish a plane of peculiar construction and organization having a detachable part, by the removal or replacement of which, the plane may be quickly and practically adapted for use either as a rabbet-plane or as a smooth-plane.

In the drawings accompanying and forming a part of this specification, Figure 1 is a plan view of a convertible plane embodying my invention, a portion thereof being broken away, the parts being assembled to adapt the plane for use as a smooth-plane. Fig. 2 is a side elevation of the same. Fig. 3 is a side elevation of a portion of the plane with the side-plate or guard-plate removed, the plane in this condition being adapted for use as a rabbet-plane. Fig. 4 is a vertical cross-section of the plane taken in dotted line a–a, Fig. 2, looking in the direction of the arrow in said figure.

Similar characters designate like parts in all of the figures.

In the drawings I have shown my invention applied to a plane, which in general construction and organization is similar to the ordinary metallic smooth-plane. The main body or rabbet-plane body, of the plane is designated in a general way by B, and consists of the usual base or sole, 3, divided transversely by the mouth 4, forming the front and rear portions 5 and 5′, and the side-walls 6 and 6’, the one 6′ of which is herein shown as divided vertically by the mouth 4, the base or sole 3 being preferably reinforced each side of the mouth 4 by the transverse ribs 7 and 7’. The main body is usually provided at the forward end thereof (shown in Figs. 1, 2 and 3 as the right hand end) with a knob or handle, 3.

The plane-iron or cutter C which may be supported in any usual manner from below, as shown in Figs. 2 and 3, and the clamp-lever D, are, or may be, of any usual construction and organization. The cutter C is shown in the drawings as having its cutting edge in the mouth of the main body and as supported upon a longitudinal rib, 9, having an inclined face coinciding with the inclined face of the reinforced portion 7 of the base, the upper face thereof being engaged by the cutting-edge, while the forward end of the clamp-lever is held in place longitudinally by a screw, 10, extending through the forward end of said lever, through an elongated slot formed in the cutter, and entering the reinforced portion 7’ of the base.

As a means for operating the clamp-lever to clamp the cutter, a screw, 11, is provided which has a screw-threaded bearing at its upper end in the rear end of the clamp-lever, and bears at its lower end upon the rear end of the cutter, said screw usually being provided, in practice, with a wheel or disk for operating the same. It is desired to state in this connection, that these elements just described, i. e. — the cutter and its clamping devices, constitute no part of my present invention, and may be of any usual construction and organization.

As a means for rendering the plane convertible, to adapt the same to be used either as a rabbet-plane or as a smooth-plane, I have provided a guard-plate or suplementary body, G, adapted to be detachably-secured to one side of the main-body so as to cover the open side of the plane and the open end of the mouth 4, and so that the lower edge of said plate will be flush with the bottom edge of said body to guard the cutter, as most clearly shown in Figs. 2 and 3. This plate or body constitutes a guard for the open end of the mouth 4, and when secured in place, as illustrated in Figs. 1 and 2, adapts the plane for use as a smooth-plane.

As a convenient means for detachably-securing the supplementary body or guard-plate to the side of the main-body, said plate is herein shown provided at opposite ends with laterally-projecting pins,12, adapted for entering holes, 13, drilled in bosses, 14, formed upon the base 3 of the main-body, as clearly shown in Figs. 1, 2 and 3, said plate being held against lateral displacement by means of set-screws, 15, extending through the bosses 14 and impinging the retaining-pins 12 of the guard-plate. These binding-screws are herein shown as having conical ends which enter recesses formed in the peripheries of the retaining-pins of the guard-plate, and have bearings in screw-threaded transverse or vertical openings formed in the bosses 14. The retaining-pins are herein shown as separate pieces fixed to the guard-plate after the manner of rivets, but it will be obvious that said pins might constitute an integral part of said guard-plate.

The above-described construction and organization constitute an improved tool adapted for use both as a rabbet-plane and a smooth-plane, the usual open-sided mouth being provided for rabbeting when the guard-plate or supplementary plane-body is removed, and the solid, unyielding structure necessary to smooth-planing being formed when said plate or body is fastened in position upon the main-body of the plane. When set in position upon said main-body of the plane, it will be seen that the suplementary body forms the main sole-piece of the plane-body for that side of the plane adjacent to the open-sided mouth; that, by means of its peculiar connection to and organization with the main-body of the plane, said plane is braced in longitudinal direction to prevent yielding thereof, which would tend to impair or destroy the efficiency of the tool for smooth-planing; and that said plate or supplementary body, when in such set position, forms the means for rendering the body of the plane a practically unitary structure, having all the characteristics necessary to perfect operation of a smooth-plane. It will also be evident that the change from a rabbet-plane to a smooth-plane, or vice versa, may be easily and quickly effected, and that, in removing the guard-plate, the holding-devices therefor will be maintained in position upon the stock.

Having thus described my invention, I claim —

1. In a plane, the combination with a main-body having a transverse mouth open at one side of said body, of a plane-cutter extending longitudinally of said body and having a transverse cutter-edge, means for securing said cutter to the plane-body in position for use and with its cutting-edge in the mouth of the main-body, and a supplementary plane-body adapted and provided with means for connection to the open-mouth side of the main-body in fixed relation thereto and having its sole in the plane of the sole of the main-body, whereby the mouth of the main body is closed on one side thereof and the edge of the cutter is guarded, thereby converting the plane into and adapting the same for use as a smooth-plane, substantially as described.

2. In a combined rabbet-and-smooth-plane, the combination of a plane-body having a transverse mouth open at one side of said body, of a plane-cutter extending longitudinally of said body and having a transverse cutting-edge, means for securing said cutter to the plane body in position for use and with its cutting-edge in the mouth of the main-body, a guard-plate covering the open end of said mouth and having its sole in the plane of the sole of the main-body, parallel lateral pins or projections fixedly carried by said guard-plate, parallel recesses in the plane-body inclosing said pins and adapted thereby to maintain a solid connection between the forward and rearward portions of the plane-body and to prevent misalignment of the soles of the plane-body and the guard-plate, and clamping-screws engaging said pins or projections for detachably securing the guard-plate to the plane-body, substantially as described.

3. In a combined rabbet and smooth-plane, the combination of a plane-body having a transverse mouth open at one side of said body, a plane-cutter extending longitudinally of said body and having a transverse cutting-edge, means for securing said cutter to the plane-body in position for use and with its cutting edge in the mouth of the main-body, a guard-plate covering the open end of said mouth and having its sole in the plane of the sole of the plane-body, parallel lateral pins or projections peripherally recessed and fixedly carried by said guard-plate, bosses formed upon said plane-body and having parallel recesses inclosing said pins and adapted thereby to maintain a solid connection between the forward and rearward portions of the plane-body and to prevent misalignment of the soles of the plane-body and the guard-plate, and clamping-screws extending through said bosses and into the recesses thereof and having conical ends for engaging said peripheral recesses in said pins and for detachably securing the guard-plate to the plane-body, substantially as described.

To all whom it may concern:

Be it known that I, THEODORE WHISTON FULLER, of Washington city, in the District of Columbia, have invented certain new and useful Improvements in Bench or other Planes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which 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 of reference marked thereon, which form a part of this specification.

My invention is an improvement on that class of bench and other planes for carpentering or wood-working, which have adjustable devices for holding the plane-iron or knife; such for instance as that patented to L. Bailey, No. 67,398, dated December 24, 1867; and it has for its object, not only to prevent the getting loose of certain parts but also to prevent the straining and wearing away of that part of the wood into which these devices are fastened, and which after a while render the plane entirely useless.

By my improvements the parts which support the plane-iron are held with it firmly to the adjusted position.

Heretofore the screws which were intended to hold the adjusting devices to the wooden body of the plane, were screwed directly into such wood. When such plane is in use the least jar knocks the cutter or plane-iron out of place. The strain and thrust come all upon these wood screws, tending constantly to loosen them by disintegrating the fibers of the wood and enlarging the screw hole until presently all possibility of a firm, fixed hold is gone, and the plane has to be replaced by a new one. This involves not only great annoyance, imperfect work in planing and frequent ineffectual efforts to satisfactorily hold the cutter to its adjusted working position, but also wastes much of the workman’s valuable time. I have therefore invented a simple, cheap, but most effective means for avoiding these difliculties, and whereby the tendency of the parts to loosen, weaken, or get out of order, are reduced to the minimum or entirely avoided.

In the drawings: Figure 1 shows in longitudinal section enough of a plane of the Bailey class as now found in the market, to illustrate my invention as applied thereto; Fig. 2, a cross-section in the line x x of Fig. 1, the cutter and its fastening plate being removed, the bolts being shown in full; Fig. 3, a plan of the two-armed metallic screw-held plate, having at the end of each arm a threaded hole for a machine-thread screw-bolt and at its angle end an unthreaded counter sunk hole for a wood-screw; Fig. 4, a front view or elevation of the same, and Fig. 5 is a detail, showing one of the machine-thread bolts in place in the plate.

A indicates the body of the plane; B, the plane-iron or cutter; C, the plate lying on and above the same; D, the cam-lever, and d’ its spring, for tightening this plate on the cutter; E, the lever supporting plate; F, the forked lever fulcrumed on this plate, and f’ the screw, and f2 the nut, for moving such lever to adjust the plane-iron longitudinally; L, the lever for adjusting said iron to insure the parallelism of the cutting edge with the bottom of the plane stock. These parts being well known, need not be more particularly described.

Instead of securing directly to the wood the plate E, which carries the forked lever and its adjusting screw, and which practice has been found so disastrous when and after its wood screws get loose, I make a stout specially-shaped two-armed plate G, the arms meeting at nearly a right angle, the plate being about three-eighths of an inch in thickness. The two ends of these arms have each also a hole g’ which is closely threaded to receive a machine-thread screw-bolt H; and at its angled end, it has a counter-sunk hole g2 to receive a wood screw g3. This plate I insert in a correspondingly shaped cavity made in the wood in the top of the plane a little back of the throat, so as to be tlush with it, and I secure it in place by the wood-screw in hole g2. The circular ends in which are threaded holes g’ serve like nuts, but being connected by the parts or webs i, j, to the circular portion g4, and all parts of the plate G being thus integral, this solid sunken plate when in place is practically immovable either forward or backward against any jar or blow, and against any and all back-thrust when using the plane; and even before inserting the screw bolts H. When the bolts H are inserted through the usual holes in plate E, their threaded ends engage respectively with the threaded holes g’ and hold the plate almost as firmly as if it were imbedded in a rock, or as if the plane stock were all of iron. It will now be seen that there can be no disintegration or wearing away of any screw-hole in the wood, for the plate is immovable relatively to the wood; the bolts H do not engage with any wood at all, and that all the thrusts are received and distributed against the entire rear wall of the cavity in which plate G is sunken; and in addition to this, this plate is fastened by its rear screw in the hole g2.

The part g4 is designedly located far enough back to permit its screw g2 to be readily inserted and removed, and the whole plate occupies a space otherwise not utilized.

It will now be seen that my improvement can be applied to any existing new, or old, or otherwise useless plane of the Bailey or similar class; that with an ordinary brace and bit, chisel and screw-driver any one can apply the plate G in a short time; that by reason of this thick threaded plate and its fine machine thread bolt, the plate E and the parts supported thereon can not only be tightened more firmly than by the means heretofore used, and held more permanently, and therefore needing less frequent adjustment, but the planes will wear and be useful for a great while longer.

My improvement is applicable to a great variety of planes, especially the jack-plane, fore-plane, or jointer and smoothing plane.

I claim —

1. In combination with a plane stock or body, a metal plate inserted in the top of the same back from the edge of the throat so as to be in closed both front and rear by the stock, the cutter supporting plate, and means whereby the same may be removably secured to said inserted plate, all as and for the purposes set forth.

2. In combination with a plane stock or body, a metal plate inserted in the top of the same back from the edge of the throat so as to be inclosed both front and rear by the stock, the cutter supporting plate, and means whereby the same may be removably secured to said inserted plate, and means whereby the inserted plate may be secured to the plane stock, all as and for the purposes set forth.

3. In combination with a plane stock or body, a metal plate inserted in the top of the same back from the edge of the throat so as to be inclosed both front and rear by the stock, and having screw threaded sockets in the same, the cutter supporting plate, and screws or bolts passing through holes in said plate into the threaded sockets of the inserted plate, to removably secure the same together, all as and for the purposes set forth.

4. In combination with a plane stock or body, a forked or angular metal plate inserted in the top of the stock back from the edge of the throat so as to be inclosed both front and rear by the stock, the cutter supporting plate, and means whereby the same may be removably secured to said inserted plate, all as and for the purposes set forth.

To all whom it may concern:

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

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

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

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

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

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

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

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

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

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

I claim as my invention —

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

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

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

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

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

To all whom it may concern:

Be it known that we, ROYAL WARNER McINTYRE and GUSTAVUS ADOLPHUS HANKINSON SPRAGUE., of Redlands, in the county of San Bernardino and State of California, have invented certain new and useful Improvements in Oil-Cups; and we 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.

Our invention is an improvement in oil cups or cans designed for greater simplicity and durability of construction and efficiency and certainty of operation.

A further object of our invention is to supply simple and useful means for lubricating the under surface of iron planes thereby dispensing with the old method of greasing the under surface of the plane with a piece of fat.

Other objects and advantages of the invention will appear in the following description in which we have set forth fully the details of construction and the essential features thereof and illustrated them in the accompanying drawings in which similar letters of reference designate corresponding parts.

Figure 1 represents a part section and side view of an ordinary plane with our invention attached. Fig. 2 is a modification.

Reference being had to the above figures A represents the main body of the oil cup which is secured to the forward portion of the plane B by means of the hollow threaded lug C. The bottom of the cup A is provided with the conical hole D the smaller end of which is at the upper surface of the bottom. The upper portion of the cup A is furnished with a convex screw cap E which is made of light spring material and is screwed to the cup in the manner shown in Fig. 1. Extending upward through the conical hole D is the valve rod F one end of the stem of which is screwed to the projection G on the under surface of the cap E while its other end terminates in a conical enlargement H corresponding to the opening in the lower surface of the cup A. It will be readily seen that when the cap E is pressed downward the valve stem F and enlargement H are forced downward thus allowing the oil to flow through the hole in the bottom of the cup A thereby lubricating the under surface of the plane.

In Fig. 2 we have changed the construction slightly and instead of the conical hole D we have substituted a hole with parallel sides and constructed the enlargement H to correspond. In this latter construction the cup is adapted to be filled through the opening in the side of the cap near the top which is closed by a screw J. It will be readily seen that it is impossible for the oil to escape from the nozzle unless the base of the can is forced inward.

The construction and arrangement of the several parts of our invention being thus made known the operation and advantages of the same will it is thought be readily understood.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent, is —

The combination with a plane, having an opening through the bed of the front portion thereof, of an oil cup resting on said bed, and having a spring actuated valve therein which is operated from the upper end, and a screw plug, C, seated within the perforated base of the cup with an opening therethrough by means of which the said oil cup is secured to the bed plane, the upper portion of said plug being formed with an enlarged chamber, with which said valve communicates, and a lower reduced opening, and the lower end of said plug extending only partially through the side of the plane, substantially as described.

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

To all whom it may concern:

Be it known that I, WILLIAM E. CROMPTON, a citizen of the United States, residing at Park City, in the county of Summit and Territory of Utah, have invented certain new and useful Improvements in Carpenters’ Planes; and I do hereby declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in planes, and especially to improvements in rabbet planes, and it consists of certain novel features hereinafter described and claimed.

The ordinary rabbet plane cuts a shaving somewhat wider than the plane, and this jams in the sides of the plane, rendering it necessary to stop to remove the same, and causing the inconvenience in working well known to persons skilled in the art. I have discovered that by splitting the shaving longitudinally, or rather by cutting a longitudinal slit in the wood before the shaving is pared oif by the bit, this inconvenience is almost entirely obviated.

My invention will be understood by reference tot he acccompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure 1 represents a longitudinal section of an ordinary form of rabbet plane along the line x’ x’ of Fig. 2, and illustrates the application of my improvement. Fig. 2 represents an inverted plan view of the plane shown in Fig. 1, and Fig. 3 represents an enlarged section along the line x x of Fig. 1, and looking down.

A represents the bottom plate or base of the plane provided with rear handle, sides B, bit C, and the other attachments commonly found in planes. The bottom plate A is slotted as at afor the passage therethrough of the bit C and of the shaving, and is also slotted at a’ to allow the passage of the knife D. The sides B are open as at b to allow the passage of the sides of the shaving.

The knife D is provided with a shoulder d resting on the tip of the spring E which is secured beneath the front handle F, and held in place by the screw G. This knife D is secured in a guide lug K, which lug is rigidly attached to the cross piece H between the sides B of the plane. A screw L is either set in or made integral with the said lug K, and on this screw the thumb wheel M is mounted, having a flange adapted to engage the upper end of the said knife D. It will be seen if the the said thumb wheel M be screwed down, that the knife D will be projected through the bottom of the plane, and that by means of the spring E, and the thumb wheel M, the knife D may be adjusted to the desired position.

The operation of the device is as follows: — The knife D and bit G being projected the required amount, which can only be determined by experiment, the plane is operated in the usual way. The knife D preceding the bit C, splits the surface of the wood in front of the said bit, and then these split parts readily slip or bend over one another, allowing the shaving to pass between the sides of the plane without jamming.

While this invention is particularly applicable to rabbet planes, it will be obvious that it may be used in connection with any of the planes ordinarily in use. In all of such planes, there is a tendency for the shaving to stick in the plane, and this is obviated by the device as already described.

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

1. In a plane, the combination with a bit of a splitting knife D adjustably mounted in front of said bit, a spring E normally supporting said knife, a guide lug K inclosing the rear sides of said knife, a screw L attached to said lug, and a thumb wheel M adapted to bear on the upper part of said knife, substantially as and for the purposes described.

2. In a plane the combination with the bottom piece A slotted as at a and a’, the rear handle, the front handle F, and screw G, the bit C, the knife D, the spring E, the guide lug K, screw L and thumb wheel M, substantially as and for the purposes described.

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

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.

To all whom it may concern:

This invention relates to that class of planes in which the plane-iron is adjustable for the purpose of bringing the same accurately into position for use, by means of adjusting-devices connected with the knife-holding apparatus.

The object of my present invention is to provide means, in a plane of the class specified, for adjusting the knife laterally thereof to bring the cutting-edge in parallelism with the face of the plane; and to make this adjustment by means of devices operating in connection with, but separately from (in point of time) the means for adjusting the plane-iron longitudinally thereof.

In the drawings accompanying and forming a part of this specification, Figure 1 is a side elevation, partially in section, of a plane embodying my present improvements. Fig. 2 is a plan view of the plane, with the cutter, or knife, and its clamp removed, and showing the knife holding and adjusting-apparatus in place. Fig. 3 is an end elevation of the plane, as seen from the right-hand in Figs. 1 and 2, the cutter or knife being in place, but the clamp-lever removed. Fig. 4 is a plan view of a portion of the plane illustrating the mode of operation of the swing-frame and the actuating lever therefor which regulates the lateral movement of the knife, the knife, knife-support and clamp being removed. Fig. 5 is a plan view of the swing-frame, in the preferred form thereof. Fig. 6 is a side elevation of the swing-frame, as seen from below in Fig. 5. Fig. 7 is an end elevation of the swing-frame, as seen from the right-hand in 5 and 6. Fig. 8 is a plan view of the swing-frame-adjusting lever, in a position corresponding to the same in Figs. 1 and 2; and Fig. 9 is a side view of said lever, in a position corresponding to that shown in Fig. 1.

Similar characters designate like parts in all the figures.

For illustrating the construction and mode of operation of my present improvements and the preferred manner of applying the same, I have shown the invention applied to an ordinary iron smoothing-plane. The body of the plane is designated in a general way by B, and consists of the usual base or face, 3, divided transversely by the mouth, 4, and having the side-walls, 5 and 6; it is usually provided at the forward end thereof (at the left-hand in Figs. 1, 2 and 4,) with a knob or handle, 7, and rearwardly of the plane-mouth with a transverse pin, 3, which serves as a bearing for the clamp-lever, D. The “plane-iron” or cutter, C, shown in section in Fig. 1 and in rear elevation in Fig. 3, is set in an inclined position as indicated in the drawings, and with its edge at 9, Fig. 1, extending slightly through the mouth of the plane. The cutter or knife C being supported from below in substantially the position shown in Fig. 1, the clamp-lever D is placed thereon, underneath and in engagement with the aforesaid transverse pin or bearing 8, and with its point, 10, resting on said knife near the lower end thereof, in the usual manner. The clamp-lever is or may be operated, for the purpose of clamping and unclarnping the plane-knife or cutter C, by means of the screw, 11, carried by said clamp, and bearing at its outward end, 12, against the upper side of the plane-knife, said screw being usually operated, in practice, by means of a wheel or disk, 13, fixed thereon.

The rearward and upper end, 14, of the cutter is shown having formed in its under side a channel whose edges at 15 and 16, form guides for controlling the lateral movement of the cutter, the channel having in the top thereof a series of teeth, 17, for engaging with the corresponding notches of the main lever, E, of the adjusting-apparatus. Said main-lever is shown carried by a pivot, 18, fixed in the ears, 19 and 19′, on the rearward end of a swing-frame, 20, which lies on the upper side of the face or bottom-plate 3 of the plane, and which is provided with means for the lateral adjustment thereof. Said swing-frame has at its forward end a bearing-arm, 21, which engages in a slot, 22, formed in the plane-body; said frame is held in place longitudinally of the plane by means of the screw-stud, 23, under the head of which is journaled the forward end, 24, of the lateral-adjustment lever, 25, this lever also having a bearing, 26, in working engagement between said ears 19 and 19′ of the swing-frame, and being provided at its extreme rearward end with a suitable termination, or thumb-piece, as 25′, whereby the same may be conveniently operated. The aforesaid screw-stud 23 passes down through the slot, 27 of the swing-frame, so as to control the position of said frame when this is swung laterally, as indicated by the two positions thereof shown by solid lines and dotted lines, respectively, in Fig.4. About midway of its length, the swing-frame 20, in the preferred form thereof herein shown, has a bearing, 28, for receiving the forward end, 29, of the longitudinal-adjustment lever, 30, this lever being pivoted on a stud, 31, between the forward ends of the said arms, 32 and 32′, of the aforesaid main lever E, and having its projecting rearward end properly shaped, or furnished with a thumb-piece, as 30′, whereby the same may be actuated for operating the main lever to slide the cutter forward or backward, as the case may require. It will be observed that the forward bearing 21 of the swing-frame is on the line e (Fig. 1) about midway between the clamp-lever bearing 8 and the point 10, where the knife is clamped between the end of the clamp-lever and the bottom-plate of the plane-body. The parts here described are organized, as set forth, so that when power is applied to the rearward end of the plane-knife for swinging the same laterally, said knife will naturally turn or swing upon an axis substantially coincident with said swing-frame bearing 21. Said lateral movement of the knife C is effected through the described main lever E, which engages at the upper side thereof between the said edges 15 and 16 of the channel in the knife. By this means, when the swing-frame 20 is moved laterally by means of said actuating-lever 25, the main-lever E, being mounted on said arm, is carried sidewise, being swung about the aforesaid axis 21 in substantial coincidence with the movement of the knife itself.

For adjusting the knife longitudinally thereof, the secondary lever 30 is raised or lowered, as the case may require, thereby swinging the main lever E on its pivot 18, and forcibly sliding the plane-knife under the rounded end 12 of the clamp-lever screw 11. And by operating the lever 25, the main-lever, also designated as the knife-actuator, is moved laterally to carry the knife side-wise as required. The swing-frame, by means of the combinations and construction hereinbefore described, is closely held in place on the upper surface of the base-plate 3, the forward end of the frame-actuating lever 25 serving as a washer between the head 23′ of said screw-stud and the swing-frame; the forward end 21′ of the swing-frame comes close to the under side of the knife C, so that said frame-bearing 21 is prevented from rising out of the bearing-slot 22.

Having thus described my invention, I claim —

1. In a plane, the combination with a plane-body, and with the knife and means for clamping the same in place, of a knife-supporting actuator-lever engaging the knife longitudinally and laterally thereof, an actuator-lever-carrying frame supported for movement laterally of the knife, and means for moving said actuator-lever on the frame independently of the movement of the frame, substantially as described.

2. In a plane of the class specified, the combination with the knife having the transverse notches and the longitudinal guide-edges, and with means for clamping the same in place, of a knife-supporting actuator-lever engaging said notches and between said guide-edges, a swinging actuator-lever-carrying frame supported for movement laterally of the knife, the screw-stud holding the frame in place, and a lever journaled on said stud and engaging the frame to move this independently of the movement of the actuator-lever, substantially as described.

3. In a plane, the combination with a plane-body, and with the knife and means for clamping the same in place, of a knife-supporting actuator-lever engaging the knife longitudinally and laterally thereof, a swinging actuator-lever-carrying frame supported for movement laterally of the knife, means for moving said frame laterally of the knife, and a lever fulcrumed. in the swing-frame and engaging the actuator-lever for operating this independently of the frame, substantially as described.

4. In a plane, a knife-supporting-and-adjusting device consisting of a laterally-movable frame having the ears 19 and 19′ and the fulcrum-bearing 28, combined with a main lever, substantially as described, pivotally supported between said ears and provided with a lever fulcrumed in said fulcrum-bearing, and means for holding in place and actuating said frame, substantially as described.

5. In a plane, the combination with the body having the frame-bearing slot 22 and the stud 23, of the frame 20 engaging at one end in said bearing-slot and having a transverse slot through which said stud extends, a lever on said stud and engaging the frame for moving the same laterally of the plane-body, and a knife-supporting-and-adjusting device carried on said frame and consisting of a lever pivoted thereto and furnished with means for operating the same, substantially as described and for the purpose specified.

6. In a plane, the combination with the plane-body and with the knife and means for clamping the same, of a longitudinally movable combined knife-support and actuator in engagement with the knife, an actuator-carrier supported for movement laterally of the knife, means for simultaneously moving the actuator-carrier and knife-supporting actuator laterally of the knife and means for moving said actuator independently of the movement of the actuator-carrier, substantially as described.

7. The combination in a plane, of a plane-body, a knife and means for clamping the same, a combined knife-support and actuator carried by a frame supported for lateral movement by the plane-body, means for independently operating the knife-support to shift the knife longitudinally, and means for adjusting the frame laterally of the knife, substantially as described.

To all whom it may concern:

Be it known that I, ALFRED A. CURRY, a subject of the Queen of Great Britain, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements in Stop and Chamfer Planes; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to produce a chamfering and molding plane that will out a stop without change of position of the cutter by the same movement that the chamfer or molding is cut, thereby doing away with the necessity of using a chisel or other tool to out stops at the end of the molding or chamfer, or with the use of a tool held in a vertical position to scrape the surface of the molding or chamfer after it has been roughened out by a routing tool. It will be seen therefore that my novel tool performs the functions both of a router and a finishing tool, in addition to cutting both stops.

In the accompanying drawings forming part of this specification Figure 1 is a perspective of my novel plane adjusted for use as a chamfer plane, the mouth piece being in section; Fig. 2 a section on the line y y in Fig. 3; Fig. 2a an inverted plan view of the forward end of my novel plane corresponding with Fig. 2; Fig. 3 a section on the line x x in Fig. 2. Figs. 4 and 7 are elevations of different forms of mouth pieces; Figs. 5 and 8 elevations illustrating cutters corresponding therewith; Fig. 6 a section on the line z z in Fig. 4 the cutter also being shown in edge view 5 Fig. 9 a section on the line m m in Fig. 7 the corresponding cutter also appearing in section; Fig. 10 a view of a molding and stop made by the cutter illustrated in Fig. 5; Fig. 11 a view of a molding and stop made by the cutter illustrated in Fig. 8, and Fig. 12 is a view of still another form of molding and stop, the latter being made by the same cutter which cuts the molding, as in the other forms.

A denotes the body of the plane as a whole, and 2 denotes the handle. These parts may be of any ordinary or preferred construction adapted to this class of work. In the plane illustrated in the drawings 3 denotes the side plates, 4 the front plate, and 5 the incline of the cutter box or blade holder, and 6 and 7 are the angle plates which engage the sides of the piece of wood to be chamfered. Angle plate 7 is not as long as angle plate 6 and terminates in a horizontal plate 8, said plate being formed integral with depending holders 9, which receive rods 10, said rods carrying at their inner ends a side gage 11 the inner face of which corresponds with the inner incline of plate 7 and the top corresponding with the under side of the horizontal plate. The adjustment of the side gage determines the depth of the cut made by the cutter in forming the chainfer or molding.

12 denotes set screws which engage rods 10 to lock the side gage in position after adjustment.

13 denotes the cutter or blade, the cutting edge of which is of course shaped to correspond with the shape of the chamfer or molding it is desired to produce, a straight edge of course producing a straight chamfer and an inwardly or outwardly curved edge producing a corresponding curve in the piece of wood that is operated upon. The cutter is held in position by the usual lever 14 which has its fulcrum on a transverse pin 15 and is provided at its upper end with a set screw 16 which is adapted to bear against the upper end of the cutter and when turned downward upon the cutter raises the upper end of the lever thereby forcing the lower end of the lever down upon the lower end of the cutter and clamping it in place.

It will be seen from Figs. 2 and 2a that the cutter or blade is not used in the ordinary way, that is with the beveled side down. In my improved plane the cutter is used with the face side down the bevel being upon the upper side so that in use I cut away the wood that is to be removed instead of scraping it away. In use the cutter or blade rests upon the incline there being no open space whatever back of or under the cutter.

17 denotes the mouth piece which I have shown as provided with side lips 18 to engage the side plates 3 of the cutter box with a lug 19 on the top through which a set screw 20 passes, said set screw engaging the top of the front plate to adjust the mouth piece, and with a slot 21 through which a set screw 22 passes which engages the front plate to lock the mouth piece in position after adjustment. The essential feature of the mouth piece is that it is provided with an operative face 23 which in all cases corresponds exactly with the curvature of the cutting edge. If the cutting edge is a convex curve, as in Fig. 5 producing a concave curve in the molding as in Fig. 10, the operative face of the mouth piece is extended outward from the vertical plane of the body thereof as clearly shown in Fig. 6. If the cutting edge is a concave curve as in Fig. 8 producing a convex curve in the molding as in Fig. 11, the operative face of the mouth piece extends inward from the vertical plane of the body thereof as clearly shown in Fig. 9.

By making the cutter box part of the body, i. e., stationary, and dispensing entirely with a front gage using a side gage in lieu thereof, I insure that the plane in use shall wear evenly from front to back. Where a front gage is used the wear is at the back of the plane which greatly shortens its life. The cutter when once adjusted does not require to be shifted in changing from one kind of work to another, the thickness of the shaving in all kinds of work being regulated by the adjustment of the mouth piece.

In use the operator selects the proper cutter to produce the molding or chamfer required, and having placed it in position with the face side down and the bevel up and locked it there, he adjusts the mouth piece to cut as thick a shaving as the quality or hardness of the wood will warrant. In case the molding is very small or the chamfer shal-
low it will be necessary to set the side gage inward. To cut a stop and a chamfer or molding the operator simply places the cutting edge at the point in the piece of wood to be operated upon where the stop is to commence and presses firmly downward and forward taking care to stop the tool before the end of the chamfer or molding is reached. He then repeats the operation from the other end, these two operations serving as a matter of fact to complete perfectly both stops and the chamfer or molding.

The side gage is to be used with a knife having either a straight cutting edge or an edge of any desired configuration. It is not necessary that the chamber should be perfectly symmetrical on each side of its center as it may be of a variety of forms and these may be secured by using a knife having a curved cutting edge and by adjusting the side gage more or less inwardly.

Having thus described my invention, I claim —

1. A chamfer plane comprising the body formed of the angle plates 6, 7, the inclined plate 5 with the side plates 3, 3, rigidly connected thereto the cross or front plate 4 connecting the side plates and constituting with them the box, the cutter arranged in said box and projecting under the front plate 4 and the vertically adjustable mouth piece carried by the said front plate 4, substantially as described.

2. In combination, the body comprising the angle plates 6, 7 with the incline 5 and the side plates 3, the cross or front plates 4 between the front ends of the side plates and constituting therewith the box of the plane, the knife arranged in the box, and the mouth plate secured adjustably to the front side of the box and having lips extending around the front corners of the box, substantially as described.

3. In combination in a chamfer plane, the angle plates 6 and 7 rigidly connected together forming a solid body portion, the knife adjustably carried by the said solid body part, one of said angle plates having a recess in its inner face, the adjustable side gage adapted to said recess to present a flush surface with the face of the recessed angle plate and movable transversely across the angular space, and the means for adjusting and holding said side gage, substantially as described.

4. In combination the angle plates 6 and 7, the knife having its front cutting edge extending to the front end of the angle plates, and the mouth plate also arranged at the front end of the angle plates above the cutting edge, said mouth plate consisting of a flat piece arranged vertically being adjustable vertically of the front end of the plane said angle plates constituting the gage frame and being free from projecting portions forward of the cutting edge, substantially as described.

5. A chamfer plane comprising the body formed of the angle plates, the side plates and the inclined plate rigidly connected thereto, the cross or front plate 4 constituting with them the box, the cutter arranged within said box projecting under the front plate and having a cutting edge adapted to form a rib or depression and the mouth piece carried by the front plate it and having a projection at its lower end extending substantially at right angles to the body of the mouth piece and conforming to the cutting edge, substantially as described.

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

To all whom it may concern:

Be it known that we, JUSTUS A. TRAUT and CHRISTIAN BODMER, citizens of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to adjustable-mouth planes, the object being to furnish means for adjusting the mouth-slide and for holding the same in place.

In the drawings accompanying and forming a part of this specification, Figure 1 is a plan view of a portion of a plane furnished with our present improvements. Fig. 2 is a sectional side view of the plane. Figs. 3 and 4 are views similar to Figs. 1 and 2, respectively, for illustrating the mode of operation of the improvement. Fig. 5 is a view-similar to Fig. 1, showing a modification of the improvement. Fig. 6 is a sectional side view of a portion of the same. Fig. 7 is a view similar to Fig. 1, showing another modiication.

Similar characters designate like parts in all the figures.

Referring to Figs. 1, 2, 3 and 4, the letter B designates the forward portion of an ordinary iron smoothing-plane of the class which are usually provided with a mouth-slide, also sometimes designated as an “adjustable front,” for regulating the width of the mouth 2, of the plane. The usual plane-iron or cutter is shown in place at 3, held under the forward end of the ordinary clamp, 4, in a well known manner.

The mouth-slide designated by 5, is shown provided with a stud, 6, preferably rigidly fixed therein as indicated in Figs. 2 and 4. Said stud 6 extends upward through the forward end, 7, of the plane-frame, and is provided on its threaded upper end with a clamping nut, 8, whereby to hold the mouth-slide in place.

According to our present improvements, the plane is furnished with a mouth-slide actuator, designated in a general way by D, and whose principal portion constitutes an adjustable block or thrust member, designated by 9, intermediate to some part of the mouth-slide and a suitable fixed stop-abutment, as, for instance, the pin 10, on the plane-frame. In the preferred form thereof shown in Figs. 1 to 4 inclusive, said actuator consists, essentially, of an eccentric disk 9; this is shown provided with a loop or outer bar, 11, bearing against the opposite side of the aforesaid abutment-pin 10, as clearly shown in said figures. By turning the actuator D toward the right-hand or left-hand, as for instance from the position shown in Figs. 1 and 2 to that shown in Figs. 3 and 4, the mouth-slide will be moved, in the present instance toward the right-hand for widening the open space, 2′ , between said slide and the cutter 3, as will be seen by comparison of said figures of the drawings. The actuator D, being set on the plane-frame underneath the clamp-nut 8, is thereby rigidly held in place when said nut is screwed down for holding the mouth-slide.

The actuator D is shown pivotally supported on the stud 6 of the month-slide 5, so that in connection with the actuator slot 12, and the abutment-pin 10, said actuator holds the mouth-slide positively against movement in either direction; said abutment-pin fitting closely but freely within said slot, and the forward and rearward sides of said pin constituting oppositely-disposed stop-abutments.

In Figs. 5 and 6 we have shown a modification of the invention, in which the actuator, here designated by D’, consists of an eccentric disk 9’, which fits on the clamp-screw 8’, and works between the forward and rearward abutrnents 14 and 15, of the plane-frame (see Fig. 6) so as to control the position of the mouth-slide in substantially the same manner as described in connection with Figs. 1 to 4 inclusive. Said disk 9′ is shown furnished with a knurled rim 16, whereby the operator may conveniently turn the actuator for adjusting the mouth-slide.

In Fig. 7 there is shown a further modification of the improvement, in which the actuator D” consists of a flat lever 17, fitted over the stud 6, (this being the same as the one shown in Figs. 1 to 4 inclusive) and having a pin or stud, 18, fitting in an eccentric groove, 19, between the forward and rearward abutments 20 and 21, formed on the plane-frame and corresponding to those shown in Figs. 5 and 6 and also (in reverse order) to the forward and rearward sides of the abutment-pin 10 shown in Figs.1, 2, 3 and 4. In Fig. 7, the clamp-nut is omitted for the purpose of more clearly illustrating the other features; but it is or may be the same as the one shown in Figs. 2 and 4. In Figs. 5 and 6, the clamp-screw 22 is shown formed integral with the head 8’, and in working engagement with the corresponding internal thread of the mouth-slide, as will be understood from Fig. 6.

Having thus described our invention, we claim —

1. In a plane, in combination, aplane frame having a stop-abutment upon the upper face thereof, a mouth-slide having a fixed stem, vertical thereto, an independently operable mouth-slide actuator supported upon the upper face of the plane-frame and engaging the stem and stop-abutment so as to rotate about said stem and against said abutment, and means for clamping said actuator against the plane-frame, substantially as described.

2. In a plane, in combination, the plane-frame having an abutment or stop upon the upper face thereof, a mouth-slide, a stern fixed at one end to the mouth-slide and having a clamp-nut adjustably secured to its opposite end, an independently operable eccentric loosely carried by the stem intermediate to the upper face of the frame and the clamp-nut and in engagement with the abutment, substantially as described and for the purpose set forth.

To all whom it may concern:

Be it known that I, CHARLES S. HINNERSHOTZ, a citizen of the United States, residing at Reading, in the county of Berks, State of Pennsylvania, have invented certain Improvements in Carpenters’ Planes, of which the following is a specification.

My invention relates more particularly to bench planes adapted to be constructed wholly or largely of metal.

The main objects of the invention are, first, to simplify the construction, and the setting and fastening of the bit, and second to make the operation more satisfactory.

The novel features of the invention are fully described in connection with the accompanying drawings and are specifically pointed out in the subjoined claims.

Figure 1 is a longitudinal section of a plane embodying my improvements. Fig. 2 is a plan view of the stock or bed. Figs. 3 and 4 are separate views of the bit-iron and of the adjustable spring plate which forms a portion of the sole.

The stock or bed A as shown is a casting, of which the main part of the base plate a3 forms the rear portion of the sole while the part of said plate forward of the mouth c’ is raised to a higher plane and has secured to its under side by means of a screw bolt b at its forward end a spring plate A’, the rear free end of which extends to the mouth c’ and is capable of being pressed downward from its normal position by means of an adjusting screw b’. This adjustable plate thus forms the forward portion of the sole.

The bit iron C is a plain plate of steel ground to a cutting edge c and slightly curved. This is placed upon the upper face of the base plate a3 of the stock with which it may lie substantially parallel as shown, the curve however being sufficient to permit the cutting edge c to be projected through the mouth c’. It is clamped to the stock by means of a fastener D. This is provided with a clamping screw E as usual, which in pressing downward the rear end of the bit-iron upon the transverse rib a2 on the stock turns the fastener upon its fulcrum trunnions d3 which engage grooves a’ in the side walls a of the stock and causes the forward end d2 of the fastener to firmly clamp the forward end of the bit iron to the stock. This fastener is provided with a handle d and with a break-iron d’ which is carried upward in front of the handle and serves to effectually turn the shavings to one side.

By my improved construction I provide an exceedingly simple plane, very economical in manufacture yet more satisfactory in operation than any plane of its class with which I am acquainted.

Having thus fully described my invention I do not limit myself to the exact construction shown, but —

What I claim is —

The herein-described carpenter’s plane, consisting of the stock or bed, having the portion of the sole atthe rear of its mouth integral with it and the forward portion formed by a separate plate and adjustable to regulate the depth of the cut, said rear portion of the stock having a rib extending upward from its upper side; the curved bit-iron, extending through the mouth of the plane and engaging near its forward end the wall of said mouth and near its rear end the rib of stock; a combined handle and holder for the bit-iron, engaging the bit-iron at its forward end and fulcrumed to the stock near its said forward end; and an adjusting screw, engaging directly the handle at one end and the bit-iron at the other end, said screw serving to press downward and hold the rear end of the bit-iron against said rib and simultaneously to force and hold the forward end of the handle downward to clamp the forward end of the bit-iron against the stock, substantially as described.

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

_________________

To all whom it may concern:

Be it known that I, WILLIAM BEDDOWS, a subject of the Queen of Great Britain and Ireland, residing at Nottingham, in the county of Nottingham, England, have invented new and useful Improvements in Rabbeting-Planes, (for which I have obtained a patent in Great Britain and Ireland, No. 1,736, bearing date 28th January, 1892,) of which the following is a specification.

My invention relates to improvements in side planes or those planes wherein the cutting edge of the iron or bit lies at the side, as contradistinguished from the bottom of the plane stock, and the object of said invention is to provide a plane of the class mentioned which is adapted to smooth the side walls of narrow grooves, quirks and beveled shoulders in wood work and which is constructed in a novel manner, whereby the edge of the iron or bit will give a clear cut, the iron being firmly bedded, fiat, and of a form capable of being sharpened and adjusted in the stock, so as to be used for a long period of time.

To these ends the invention consists in the novel construction and combination of parts hereinafter described and claimed, reference being had to the accompanying drawings, wherein —

Figure 1, is a side elevation of a plane constructed according to my invention. Fig. 2, is an end elevation thereof. Fig. 3 is a cross sectional view taken on the line x–x Fig. 1. Fig. 4 is a plan view, the iron or bit and its retaining devices being removed. Figs. 5 and 6, illustrate, respectively, a face and an edge view of the plane iron or bit. Fig. 7 is a detail vertical sectional view of the iron or bit retaining plate. Figs. 8 and 9 are, respectively, plan and end views illustrating a different arrangement. Figs. 10, 11 and 12, illustrate, respectively, plan, edge, and end views of a triangular plane iron or bit. Figs. 13 and 14, illustrate, respectively, a side view and a longitudinal section of a construction particularly adapted for curved work. Fig. 15, is a detail transverse sectional view, illustrating another arrangement. Figs. 15a, 16 and 17, illustrate, respectively, a side elevation, an end view and a plan view of a further different arrangement. Figs. 18 and 19, are sectional views, taken, respectively, on the lines 18–18 and 19–19, Fig. 15a.

In said drawings the reference letter a designates the plane stock or body which is substantially triangular in section and of narrow dimensions transversely or in width and which is provided with a vertical working side face, the width of the upper part of the stock being comparatively large, so as to form a firm and strong bed or support for the iron and to give rigidity to the tool, while the lower part is extremely narrow and may be only one-tenth or one-twentieth of an inch in transverse section, so as to permit its entrance into narrow grooves in wood-work, to plane or smoothen the side walls of such grooves. Said stock is provided with an iron or bit-receiving channel b which extends from the top to the bottom of the stock a in an inclined, forward direction, as best shown in Figs. 1, 13, 15a and 20, of the drawings, and which also slants laterally, or extends in a transversely inclined direction from its commencing end b’ to its finishing end f.

In order to employ an iron or bit of flat form and having the advantages above described, in a stock which has an inclined mouth, that is to say, a mouth making any angle say from ten degrees to eighty-nine degrees with the bottom or riding edge of the plane, the iron or bit and its channel or bed are so inclined or canted with respect to the face or side of the plane stock as indicated by the reference letter b3, as to bring the cutting edge of the iron in the mouth when the iron or bit is in place in said channel. This will be better understood by reference to Figs. 1 to 6 and 15 to 19 of the drawings which show stocks with the mouth inclined at angles less than ninety degrees and by reference to Fig. 13, which represents a stock with the mouth at ninety degrees to the bottom or riding edge.

The reference letter c indicates the plane iron or bit having a cutting edge g formed at an angle with the side edge of the said iron or bit, the cutting end being of the same thickness as the remainder of the iron or bit and with a top beveled cutting edge, that is to say, the cutting edge when in place in the mouth slants away from the face, the fiat or unbeveled side of the iron being toward the bed, so that a thin or thick shaving may be produced and the acuteness of the cutting edge increased or decreased in sharpening as desired, the shavings being similar to those produced by ordinary surfacing planes in contradistinction to planes for cutting cigar lighters which have an inclined iron in a more or less rectangular stock and are designed to produce a shaving of a special form, and which cannot be used for surfacing, and which is adapted to be placed in and removed from the channel b, and when in operative position in said channel its cutting edge lies in the rearwardly inclined finishing end f of said channel.

The mouth f of the stock may be at any desired angle with respect to the bottom edge of the plane, the angle being different according as the plane is intended for surfacing soft, fibrous or hard woods, and as it is desired that the iron shall have a more or less shear cut.

The plane iron or bit c is firmly retained in position in the channel b as illustrated in Figs. 1, 2 and 3, by means of a retaining plate d which lies over the channel b and is provided with a flange d’ which bears upon the plane iron or bit c when it is forced in the proper direction by the screw e which passes through an orifice in said plate and has a screw-threaded engagement with the plane stock; a, as clearly shown.

In Fig. 15, I have shown the retaining plate held in place by a bolt e’ passing therethrough and through the stock a, a nut e2 engaging the end thereof, by turning which nut the retaining plate is tightened to clamp the plane iron or bit in place, or loosened to permit its removal.

In Figs. 8 and 9, the plane iron or bit c is shown retained in place by means of a wedge h, the retaining plate d, and its screw or bolt being dispensed with. In this construction the upper part of the stock a is enlarged so as to receive the plane iron or bit and wedge, the wedge being driven into place in the channel to forcibly hold the iron or bit within the channel.

In Figs. 10, 11 and 12 a plane iron or bit c’ is shown triangular in cross section so that it will accurately fit and fill the channel b, which is also triangular in cross section.

A plane particularly adapted for curved work is illustrated in Figs. 13 and 14 wherein the dimensions of the bottom edge of the stock a’ are greatly reduced. In these figures I have also shown a different arrangement of devices for retaining the plane iron or bit in place, that is to say, a retaining lever j and thumb screw k, the fulcrum of the lever being a bar, bridge or pivot l, fixed to or cast in one piece with the stock a’, as shown in section Fig. 14.

In Figs. 15a to 19, I have shown other means for retaining the plane iron or bit in place, wherein the letter a indicates the plane stock; b, the channel and c, the plane iron secured in the channel by the retaining block d3 and screw e3 which engages the screw socket in the retaining block d3 and bears at its inner end against the plane iron c.

It will be understood that the degree of inclination possessed by the channel b herein described may be varied to suit different conditions without departing from the scope of my invention, and that a side rabbeting plane having a stock wide at the top and narrow at the bottom so as to be capable of entering narrow grooves and yet forming a strong, firm support for a single, flat or triangular section top beveled adjustable iron or cutter, which lies in the bed of the stock which bed is inclined from top to bottom and also slants transversely of the stock and is capable of being easily clamped or secured in position in said bed, may be made with the bottom or riding edge of various lengths according as the tool is intended for straight or curved work, for rough or fine work, and also that the mode or means of clamping the iron or bit may be varied, the wedge as in Figs. 8 and 9 being preferable for deep narrow grooves and the means shown in Figs. 1, 2, 3, 13,15, 16, 17, and 18 being more desirable for shallow grooves or large work. For this reason three methods of clamping are shown and described. The plane stock is so shaped at its upper part as to be easily held in the hand of the user.

Having thus described my invention, what I claim is —

1. In a plane, the combination with a transversely narrow stock, having a vertical working side face, and provided with a channel which is inclined from top to bottom of the stock and slanted transversely of the stock, and one side wall of which is canted, whereby said channel terminates in a rearwardly inclined opening in the vertical working side face of said stock, of a plane iron located in said channel with its cutting edge lying in a rearwardly inclined direction with respect to the working face of the stock, and means for holding said plane iron in position, substantially as described.

2. In a side rabbet plane, the combination with a channeled plane stock of substantially triangular section and having a slit or mouth in the vertical side face thereof, of a uniform iron or cutter having a top beveled cutting edge angularly to the sides of the iron or cutter, and devices for holding said iron or cutter in position, substantially as described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

To all whom it may concern:

Be it known that we, GRANVILLE W. WRIGHT and ALBERT A. PAGE, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Bench-Planes; and we 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 view in side elevation of one form which a plane constructed in accordance with our invention may assume; Fig. 2, a plan view thereof; Fig. 3, a view thereof in central vertical longitudinal section on the line a–b of Fig. 2; Fig. 4, a view of the plane in transverse section on the line c–d of Fig. 3; Fig. 5, a view in transverse section through the stock of the plane on the line e–f of Fig. 1; Fig. 6, a detached view through the clamp of the plane on the line g–h of Fig. 2; Fig. 7, a detached plan view of the box or housing; Fig. 8, a similar view thereof in side elevation; Fig. 9, a detached reverse plan view of the secondary adjusting lever.

Our invention relates to an improvement in bench-planes, the object being to produce at a low cost for manufacture, a simple, light, durable and convenient article.

With these ends in view, our invention consists in a bench-plane having certain details of construction as will be hereinafter described and pointed out in the claims.

In carrying out our invention we form a stock A, from a single piece of heavy sheet-metal, which is struck into the required shape, the stock having the usual side flanges A’, and in addition thereto upturned end flanges A2 A2, into which the side flanges merge, as clearly shown by Figs. 1, 2 and 3 of the drawings. The stock thus formed will naturally have rounded side and end corners a, as shown in Figs. 4 and 5 of the drawings, that being an advantageous form, as such corners are less liable to mark or mar the article being planed than the sharp corners of planes having their stocks cast. The said stock is constructed with a transverse slot A3, located in the usual place, its rear wall of being beveled, as shown by Fig. 3 of the drawings.

Within the stock we locate a box or housing B, which we preferably strike up from a single piece of sheet-metal. This box may be said to be U-shaped in transverse section, and is arranged with its open side downward, as shown in Fig. 4 of the drawings, its edges being furnished with projecting lugs b b, by means of which it is secured to the stock A, the bottom of which is thereto provided with openings of suitable form to receive the said lugs. The box tapers gradually from its rear to its forward end, so as to form an inclined bed for the bit C, of the plane to rest upon. It also tapers laterally, growing wider from its rear to its forward end, so that it will form a wide bearing for the bit behind the cutting edge thereof. The vertical taper of the box is clearly shown by Fig. 8 of the drawings, while its lateral taper is seen in Fig. 7 of the same.

About midway the length of its inclined upper face or bed, the box is provided with a coupling-stud D, which stands at a right angle to the said bed. At its rear end the box is constructed with an elongated slot E, through which the teeth f of the primary adjusting-lever F, project, the said lever being hung upon a horizontal pin G, the ends of which are mounted in the sides of the box. Two thick washers G’ G’ located upon the said pin G, on opposite sides of the said lever F, prevent the same from lateral displacement on the pin. The outer end of the said lever is provided with an open longitudinal slot F’, which receives the knurled edge of an adjusting-nut H, mounted upon a threaded stud H’, secured in a vertical position to the rear end of the stock A. We do not, however, claim the said lever, nut or stud as new, for corresponding parts have been before employed for the same purpose in bench-planes. We have called the lever in question the primary adjusting lever because its function is to move the bit longitudinally to project its cutting edge from or withdraw it into the slot A3 for securing more or less depth of cut as required. The bit C is constructed upon its under face with a series of transverse grooves c, which are taken into by the teeth of the primary adjusting lever F, and which are located in the rear of its longitudinal slot C’, with which it is provided to adapt it to fit over the coupling-stud D, and be longitudinally adjusted. A secondary adjusting-lever I, projecting at its rear end slightly beyond the rear end of the bit, is pivotally attached to the lower face thereof by means of a screw I’, the forward end of the said lever being offset as at i, and then extended forward, whereby it is adapted to enter the open rear end of the box or housing B, with the side walls of which its forward edges engage to secure a purchase for the lateral adjustment of the bit, which it shifts to keep square with respect to the position of its cutting edge in the transverse slot A3 in the stock. The offsetting of this secondary lever in order to enable it to enter the rear end of the housing, will be proportional to the thickness of the metal from which the housing is formed.

We do not broadly claim a bit having a secondary adjusting lever secured to its lower face as described, except when its forward end is offset downward to adapt it to enter last the housing. We have called the lever described the secondary adjusting lever, because its function of laterally adjusting bit for squaring its edge in the slot in the the body of the stock seems secondary to the longitudinal adjustment of the bit.

The clamp J, of our improved plane, we prefer to strike from a single piece of sheet-metal in substantially the form which clamps of bench-planes ordinarily have, except as will be specified. Toward its forward end the clamp is constructed with an opening J’ , adapted in size to pass the head of the coupling-stud D, and with an open slot J2, leading forward from the said opening, and narrower than the same, the said slot being flanked on each side by horizontal flanges J3 J3, which form bearings for the head of the said stud. Under this construction the clamp is adjusted over the coupling-stud upon the bit, and then drawn rearward for locking it in place, and the more it is pushed rearward after it is in place, the tighter it will clamp the bit. This is an obviously advantageous construction, for when the plane is used, the tendency will be for the bit to be pushed rearward, and thus to only more firmly lock the clamp in place. In planes as ordinarily constructed, the operation of the clamp is just the reverse of this. The clamp is provided in its rear end with an internally threaded socket K, which receives an adjusting-screw L, which is staked, or otherwise secured into a sheet-metal hand-wheel M. The head L’ of the screw projects below the outer face of the wheel in position to be engaged with the upper face of the bit to the rear of the slot C’ therein, in the ordinary manner.

In our improved plane as herein described, the stock, the housing or box located therein to form a bed for the bit, the clamp, and the hand-wheel are struck from sheet-metal. We would have it understood, however, that we do not limit ourselves to using the said parts in combination, but we may use any one of them, or any combination of them. By constructing the said parts of sheet-metal, we secure lightness and rigidity, and an increase of room within a plane of given size. We are also enabled to give the plane pleasing lines, and to produce it at a comparatively low cost for manufacture, and obviously the sheet-metal enables it to be given at a comparatively small expense, a very high finish. Nor do we limit ourselves to the particular construction and arrangement of parts shown and described, for the devices represented for adjusting the bit both longitudinally and laterally, may be replaced by other devices.

We would therefore have it understood that we do not limit ourselves to the construction herein shown, but hold ourselves at liberty to make such variations therefrom as fairly fall within the spirit and scope of our invention. We are aware, however, that we are not the first to utilize sheet-metal in the construction of bench-planes, a plane having a wooden stock reinforced by a wrought metal covering being old.

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

1. A bench-plane having its clamp struck out from a single piece of sheet-metal, and provided within its rear end with an internally threaded socket, which receives the adjusting screw carrying the hand-wheel, and constructed at its forward end with an opening, and with an open slot leading forward from the said opening and narrower than the same, the said slot being flanked on either side by flanges set inward from the face of the clamp, substantially as described.

2. A bench-plane having its clamp constructed with an opening to receive the coupling-stud of the plane, and with an open slot narrower than the said opening, extending forward therefrom and flanked on each side by horizontal flanges set down below the face of the clamp, substantially as described.

3. A bench-plane having a sheet-metal stock, having up-turned side and end flanges, a sheet-metal box or housing secured thereto with its open side downward, by means of lugs formed upon its lower edges, inclining and widening fromits rear to its forward end and forming an inclined bed for the bit, a bit and a wide bearing just back of the cutting edge thereof, a sheet-metal clamp, a clamping-screw carried thereby, and means for adjusting the bit longitudinally and laterally, substantially as described.

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