To all whom it may concern:

Be it known that I, JUDD W. MONTAGUE, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Rabbeting-Planes, of which the following is a specification.

This invention relates more especially to planes intended for cutting rabbets in straight or curved corners of wood and for beveling or rounding such corners but the invention can be used for planing flat surfaces.

The object of the invention is to provide a tool of this kind that shall be of simple and economical construction and of easy manipulation.

The invention is embodied in the construction and combination of parts herein shown and described and then pointed out in the claims.

In the accompanying drawing Figure 1 is a view of that side of the device containing the chisels or bits and adjusting devices therefor a small portion being broken out to show a detail. Fig. 2 is a side view of the mainframe with the bit receiving frame removed. Fig. 3 is a top plan view of the bit and knife with the devices for holding and adjusting them. Fig. 4 is a view of the left hand end of the tool as shown in Fig. 1, to illustrate the guides.

In the views 10 designates the main frame and 11 the stock or bit carrying frame. These two frames are of arch form and the stock is secured to the side of the main frame by means of suitable screws such as seen at 12 passed through the three holes at 12a, 12a 12a (see Fig. 2) into holes tapped in the stock so that when the two are secured together they appear as in Fig. 1.

The stock or bit carrying frame is equipped with a bit and knife at each end so that the implement can be used for either right hand or left hand work or by forward or rearward operation. As the equipment at each end is symmetrically like that at the other in construction and arrangement a description of one equipment will suffice for both.

Referring more particularly to Fig. 3 which best illustrates the cutting equipment and the adjusting devices therefor, the character 13 designates the chisel or bit and 14 the knife the former having an ordinary slanting edge 13a and the latter a short cutting edge 14a standing at right angles to the forward portion of the slanting edge of the bit so that the two together cooperates at the forward portion of said slanting edge to cut out a corner. The shank portion of the knife is superimposed on that of the bit and is held thereon by a clamping piece or cap 15 placed under lips 16 extending upward and inward from the carrying frame or stock 11 said piece 15 being provided with a set screw 17 pinching the upper side of the knife.

The shank 13b of the bit is provided with a longitudinally extending screw 13c, a laterally extending screw 13d, and a lateral recess providing walls 13e and 13f. The screw 13e is provided with two nuts 18 and 18a and the screw 13d is provided with nuts 19 and 19a and 19b, The nuts 18 and 18a project at their lower portions into a recess 20 in the bit stock and can be turned on the screw against the walls of said recess to lock the bit shank and bit from movement longitudinally on the stock and the lower portion of the nut 19 projects into a groove 21 in the stock to prevent lateral movement of the bit shank. The shank of the knife 14 is provided with a screw 14b having thereon two nuts 22 and 22a that project into the lateral recess of the bit shank and can be turned against the walls 13e and 13f of the recess forming them to prevent longitudinal movement of the knife blade on the bit; and the screw of the knife shank lies between the nuts 19a and 19b and is prevented from movement laterally with reference to the bit by said nuts, when these are turned to lie against said screw. From this construction it will be observed that the bit can be given its proper position on the stock and the knife can be given its proper position on the bit, and further that when the knife is placed in proper position with reference to the bit both together can be adjusted to proper position.

Each end of the bit-carrying frame is provided with a guide to contact with the upper side of the wood to be rabbeted, beveled or rounded, said guide consisting of a vertically arranged headed screw 23 having on it a nut 24 said nut being located between fixed lateral projections or bars 25 and 26 on the side of the bit carrying frame and a nut 27 to pinch the under side of the projection 26 after the screw or guide has been properly adjusted. Each end of the main frame is provided with a guide to contact with the vertical or upright side of the wood to be rabbeted, beveled or rounded, said guide consisting of a horizontally arranged headed screw 28 having on it a nut 29, said nut being located between fixed projections or ears 30 and 31 on the main frame and a nut 32 to pinch the outer ear 31 after the screw or guide has been properly adjusted. The ears or projections 30 and 31 are formed on a block 33 detachable from the foot of the frame, said block being provided with a pin 33a to enter a socket in said foot and a set screw 34 screwed into a suitable hole in the foot. This block 33 and its contained guide can be removed and the plane used for planing fiat or other surfaces.

The arched form of the main frame and the bit carrying frame when combined permit the gripping of the device with the hand at either end according to the direction in which it is desired to push the device. The planing operation can be performed by either pushing or drawing the device and with the tool grasped either in left hand or right hand manner. In other words the manipulation of the plane can be accommodated to the grain of the wood and so as to avoid as far as practical planing against grain. The knife insures a smooth clean surface at the upright or vertical side of the rabbet. With this construction, and particularly because the cutting corner is free from obstructing parts in front of it two rabbets can be made with great facility in circular, oval or other curved pieces such for example as picture frames and other like structures.

What I claim is:

1. In a plane, the combination with a stock, of a bit with means in connection therewith for longitudinally and laterally adjusting the same with reference to the stock, a knife to angularly cooperate with the cutting edge of said bit, and means connected with the bit and knife for operating the knife to adjust the same with reference to the bit, the knife being movable by moving the bit.

2. In a plane, the combination with a guiding and holding stock, of a removable bit and a removable angularly cooperating knife on the bit, means on the bit for operating the knife to adjust the same with reference to the bit, and means for fixing both the bit and knife to the stock with their cutting edges wholly forward of the material of the stock.

3. In a plane, the combination with a stock, a bit and a knife, means for securing the knife to stand at one end of the edge of the bit and at an angle to the edge of the bit to form a cutting corner, combined with an arched handling frame 10 and means for securing the stock thereto at the side of the latter opposite that containing said cutting corner.

4. In a plane the combination with the stock having a recess 20 and a groove 21 of a bit provided with a longitudinally extending screw 13c and a laterally extending screw 13d and a lateral recess providing walls 13e and 13f, nuts 18 and 18a on the screw 13c extending into said recess 20 and nuts 19 and 19a and 19b on said screw 13d, the nut 19 projecting into said groove 21, a knife having its cutting edge standing at an angle to the cutting edge of the bit and cooperating therewith, said knife provided with a longitudinally extending screw 1 having nuts 22 and 22a thereon projecting between the walls 13e and 13f and said screw lying between the nuts 19a and 19 whereby the bit can be adjusted independently of the knife and the knife independently of the bit, substantially as described.

5. In a plane the combination with the stock having a recess 20 and a groove 21, of a bit provided with a longitudinally extending screw 13c and a laterally extending screw 13d and a lateral recess providing walls 13e and 13f, means on the screw 13c extending into said recess 20 to adjust and fix the same with reference to the stock, and nuts 19 and 19a and 19b on said screw 13d, the nut 19 projecting into said groove 21, a knife on the bit having its cutting edge standing at an angle to the cutting edge of the bit and cooperating therewith, said knife provided with a longitudinally extending screw 14b having means thereon to engage the aforesaid walls 13e and 13f to longitudinally adjust and fix the same and said screw lying between the nuts 19 and 19a, whereby the knife can be adjusted independently of the bit and the bit independently of the knife, substantially as described.

To all whom it may concern:

Be it known that we, MICHAEL J. DUNN and WILLIAM H. MONTGOMERY, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Bench-Planes; 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 relates to mechanical appliances for effecting the up-and-down or longitudinal and the lateral or sidewise adjustments of a bench-plane bit; and it consists, first, in a longitudinally-adjusting mechanism comprising a pivoted lever-link and a screw-threaded link, the former being pivoted to the base or frog-plate of the plane and connected with the cap-iron of the bit, and the latter also connected to a bracket of said frog-plate and provided with a thumb-nut, as will be hereinafter described, whereby the adjustment back and forward on an inclined plane in a longitudinal direction can be perfectly and readily effected, and, while this is the case, the parts for making such adjustment are readily accessible.

It consists, second, in a novel combination of the bit, cap-plate, slotted frog-plate, and a lever having its lower end pivoted in the slotted upper end of the frog-plate and pivotally connected at its lower end to the upper end of the bit. By this construction the lateral adjustment of the bit for the purpose of bringing its cutting-edge parallel with the face of the plane, and thereby securing an even cut, is cfected, and as the lever is pivoted at nearly the extreme upper ends of the bit and frog-plate we are enabled to use fully two inches of the cutting-bit before substituting a new one therefor, and, while this is so, the lever is in convenient location for being manipulated by the user of the plane.

In the drawings, Figure 1 is a vertical longitudinal section of a bench-plane with our invention illustrated thereon. Fig. 1x is a detail back view of the frog-plate. Fig. 2 is a top view of the bit and its cap-plate, and the lever for effecting the lateral adjustment. Fig. 3 is a top view of the frog-plate, the connecting-screw, and the lever for effecting the lateral adjustment. Fig. 4 is a side view of the laterally-adjusting lever and its fulcrum-pivot.

A in the drawings represents the plane-stock, which is preferably of the construction shown, but may be of any other suitable construction adapted for having our invention applied to it.

B is an inclined base or frog-plate secured by screws in a shouldered mortise a, of the stock A and sustained by a projecting thickened portion b2, which bears upon the top of said stock, while the front end of the frog-plate abuts against the shoulder a’ at the front of the mortise of the plane-stock, as shown. This frog-plate is provided with a cavity c, a short longitudinal rectangular slot b, and a long longitudinal slot b’, as shown in the drawings.

C is the plane-iron; D, the cap-plate thereof, and E a clamping-plate for holding the cap-plate D and bit C in position. The three plates C, D, and E are connected together by a screw e, which passes through a key-hole-shaped passage f in the clamping-plate E, a round hole g in the plate D, and a long slot h in the bit C and enters a screw-threaded socket i at the lower end of the frog-plate B. The cap-plate D and the bit C are connected to each other directly by means of a headed nicked screw j, the shank of said screw being passed up through cap D and its end screwed into said cap, while the head of the screw binds against the under side of the bit C and extends into the cavity c of the frog-plate B, as shown. The slot h, of the bit is enlarged into a round hole h’ for the purpose of allowing the head of the screw j to pass through the bit C in the fitting together or separation of the cap-plate D and bit C. At the upper end of the clamping-plate E a cam-lever F is pivoted for the purpose of causing a bind upon the cap and keeping its front edge parallel with the edge of the bit C or at right angles with the sides of the plane-stock A.

G is a jointed adjusting device consisting of a screw-threaded link G’ and a lever-link G2, pivoted in the walls of the slot b of the frog-plate, as indicated at k’. The upper arm m’ of the part G2 of the jointed adjusting device is extended in width or laterally and enters an oblong transverse slot m, in the cap-plate D, the said oblong slot being of slightly greater area th an the end of the said arm, so as to permit freedom of movement of the bit C and cap D in a lateral direction, and also allow the said arm slight movement in a direction longitudinally of the plates, and thus prevent binding and interference during the manipulation of the parts in making the necessary lateral and longitudinal adjustments of the bit C. The lower arm kof the said portion G2 is pivoted to the slightly-inclined screw-threaded link G’, said screw-threaded link passing between the prongs of the bifurcated bracket B’ of the frog-plate B and being condfied therein, so as to act with a frictional bind against a too great descent after an adjustment is made, by means of a collar n and a milled button n’ of a nut n2, said nut ntting and receiving the screw-threaded portion of the said link G’, and its collar n bearing on or occupying a position in close proximity to the front side of the bracket, while the button bears against or occupies a position close to the rear side thereof, and the frictional bearing action taking place when the gravity of the link G’ is unrestrained by the hand of the operator. The link G’ and its nut n2 are free to slide up and down upon the bifurcated bracket when the said frictional binding action is relaxed and the shortening and lengthening of the lever-link-adjusting device is being effected. The relaxation of the binding action may, when necessary, be accomplished by slightly lifting the link G’ to a position at a right angle to the prongs of the bracket, this adjustment overcoming the binding action which takes place when the said link by its gravity moves slightly out of a right-angular position with the prongs of the bracket. By turning the nut n2 in one direction the said adjusting device G is brought to a straighter condition, and the arm m’ is forced forward and caused to move the bit C and cap-plate D on an inclined plane downward and forward, and thereby effect the necessary or desired longitudinal adjustment, which adjustment can be made with the greatest nicety and with great convenience, as the links G’ and G2 are both supported by extensions or projections of the frog-plate, as represented.

H is a hand-lever with its handle bent upward slightly. The lower portion of this lever, between its extreme lower end and its rear upwardly-bent end, is parallel with the under side of the bit C and upper side of the frog-plate B and occupies a position between said plates. The lower end of the lever is turned upward, so as to form a pivotal toe p, and this toe passes up through a hole or slot in the bit C, said hole or slot being not far from the upper end of said bit-plate, as shown. Just in rear of this toe a pivot-pin p’ is inserted and fastened to the lever, said pin working loosely in the longitudinal slot b’ of the frog-plate B, being held in said slot by means of a head formed on it, (the pivot,) as shown. By means of the lever H the bit C can be adjusted laterally, it being simply necessary to move the handle end of the lever slightly to the right or left, as occasion may require, in order to cause the toe go to force the upper end of the bit sufficiently far sidewise to bring the lower edge of said bit parallel with the face of the plane-stock. The slot b’ in the frog B allows the pivot p’ to change its altitude accordingly as may be necessary when the bit C is adjusted up and down.

By our laterally-adjusting means described simplicity is secured and reduction of cost effected, and about two inches of the cutting-bit can be utilized before it is thrown aside, which is important.

A further advantage results from attaching the lever for producing the lateral adjustment very near the upper end of the cutting-bit and at a greater distance from the point where the bit is clamped and held in place, as by this arrangement we secure more leverage and the movement of the bit is more readily effected. This is due to the fact that the pivot-pin of lever H can occupy a position at any point along the entire distance of the slot in the frog-plate — a result not practicable unless the parts are constructed and arranged as we show. It is by this construction that we are enabled to use the bit entirely up to the beginning of the slot. In our construction we use but one hole in the bit.

We are aware of Patent No. 378,498; but with such patented plane our invention could not be employed, as said plane uses only a single bit, while our invention can only be used with a double or capped bit, and, besides this, a longer slot must be provided than is shown in Patent No. 378,494 to permit the bit to be used entirely up to the beginning of the slot, and should a longer slot be adopted in said patent the hole therein shown would have to be done away with, and this would interfere with the using of the bit entirely up to the beginning of the slot.

What we claim as our invention is —

1. The jointed adjusting device G, comprising the lever-link G2 and the screw-threaded link G’, pivoted by its forward end to the link G2 and having nut n2 and button n’, in combination with the frog-plate B, having bracket B ‘, the bit C, and cap-plate D, the whole constructed and arranged substantially as described.

2. In a double or capped bit, in combination, a bit C, cap D, clamp E, frog-plate B, and lever H, provided with the toe p, extending above its upper surface at its forward end, and the pivot-pin p’ nearly at its forward end and extending downward from its lower surface, the said pivot-pin and toe of the lever being connected, respectively, with the frog-plate and the bit near their rear ends, and the said frog-plate being slotted, as at b’, forward of said points of attachment of the lever, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.

Specification forming part of Letters Patent No. 178,256, dated June 6, 1876; application filed March 15, 1876.

To all whom it may concern:

Be it known that I, SAMUEL WILLIAMS, of Columbus, in the county of Franklin 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 thereof, 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 the letters of reference marked thereon, which form a part of this specification.

In the accompanying drawings, Figure 1 is a side elevation of a plane with my improvement attached thereto. Fig. 2 is a vertical transverse section of the same on the line x x, Fig. 1. Fig. 3 is an end view, showing the motion of the guide in dotted line. Fig. 4 is a full-sized view of the clutch-bolt and thumb-screw. Fig. 5 shows a detached modification.

My invention consists of certain novel combinations and arrangements of devices for a simple and efficient bevel-guide for planes, the details of which will be fully understood by the following description:

ln the accompanying drawings, A is a plane-stock, with a groove, B, out in each side, to receive the adjustable slide C, which is cast in the same piece with the male part F of the hinge. This slide has a rib, c, which fits the groove B of the plane, in order to prevent the slide from swinging, and thus throwing the bevel-guide out of place. The guide D is attached to the hinge-piece E, which is very strong, and has a slot with broad bearing-sun faces, to grasp the male part F of the hinge, and hold the same firmly in place. This hinge has a central pivot, G, and a set-screw, H, which passes through the curved slot I, Fig. 2, in order to adjust the bevel-guide to any desired angle. A clutch-bolt, K, passes through the plane-stock A, as shown in Fig. 4, and has one end provided with the clutch K’, to grasp the slide C, while the other end is provided with a thumb-screw or nut, L, and washer, M, for fastening the guide to the plane.

The hinge may be graduated in an arc, so as to set the guide D at any desired angle, as is well understood.

Instead of the clutch- bolt K, an arched plate, N, with a set-screw, O, may be used; but I prefer the clutch-bolt shown in Fig. 4.

If necessary with long planes, two clutch-bolts and two hinges may be used to hold the guide more securely in place.

This guide is very simple, and yet strong and durable, and it is very convenient of adjustment, and may be easily changed from one side of the plane to the other, and thus enable the workman to plane cross-grained stuff, and also prevent the uneven wear of the bit.

Having thus described my invention, I claim —

The slide C, provided with the rib c, in combination with the bolt K, bevel-guide D, and plane-stock A, substantially as and for the purposes set forth.

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

SAML. WILLIAMS.
