MITER OR BEVEL PLANE.

SPECIFICATION forming part of Letters Patent No. 553,322, dated January 21, 1896.

Application filed Octoberl, 1895.

To all whom it may concern.-

Be it known that we, J UsTUs A. TRAUT and- EDMUND A. SoHADE, 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 Miter or Bevel Planes, of which the following is a specification.

This invention relates to planes, more particularly of that class designated as miter or bevel planes; and the object of the invention is to provide an improved plane of this class more especially adapted for work on moldings and similar materials, whereby the same can be properly planed to permit the same to be joined with a miter or bevel joint, as desired.

The further object of the invention is to provide adjustable means in connection with and preferably embodied in the adjusting or gaging means whereby said adjustable means can be adjusted and held in engagement with the stock of the plane at whatever angle the gaging or adjusting means maybe positioned, to thereby constitute at all times a support for the material, whether the gaging means be adjusted in position adjacent to the planestock or not, and also to provide means in connection with such adjustable means whereby 0 when the same is in engagement with the stock of the plane the projecting plane-iron will not strike the same, on the movement of the plane in either direction.

In the accompanying drawings, forming a part of this specification, Figure 1 is a top view of my improved miter or bevel plane, and showing a piece of work in position to have one of its ends cut at an angle of fortyfive degrees, whereby, in connection with a similar molding it will form a miter-joint. Fig. 2 is a front view of the miter or bevel plane, showing the plane proper drawn away from the work. Fig. 3 is also a top view, parts thereof being broken away, and shows the gaging or adjusting means disposed at an angle of about eighty degrees relatively to the race or guideway of the plane, and also shows, in dotted lines, the adjustable means in connection with the gaging device for sup- 5o porting the material in its position adjacent Serial No. 564,327. (No model.)

to the stock of the plane, and Fig. -l is a transverse partly-sectional view, in line a a, Fig. 1, looking toward the right hand in said figure.

Similar characters designate like parts in all the figures of the drawings.

Our improved miter or bevel plane, in the preferred form thereof herein shown and described, comprises a suit-able supporting means or base (designated in a general way by A) for supporting a suitable plane (designated in a general way by B) adapted to be moved to and fro thereon, a suitable adjustable gaging or adjusting means (designated in a general way by C) for supporting the work at any desired angular position rela tively to the plane 13, and adjustable means (designated in a general way by D) preferably embodied in the gaging or adjusting means for supporting the work in position adjacent to the plane, whether the gaging means be adjusted to a position adjacent to the plane or not, and which embodies means for preventing the plane-iron from striking said adjustable means.

The supporting means or base A may be of any desired and suitable construction adapted to support the devices above mentioned, and is provided with a race or way 10, constructed in any suitable way, in which the stock 11 of the plane 13 is adapted to move to and fro. Adapted to slide in this race 10 is a plane B, constructed in any suitable way to accomplish the desired object. In the form shown, however, it comprises a rightangled stock 11, one member l) of which slides in the race or way 10, while the other member 0 thereof, which is at right angles to the supporting means A, is provided with the plane-mouth 15, hereinafter described. The members I) and 0- may be secured together in any suitable way and reinforced by suitable ribs, as desired. Secured to this stock 11, preferably adjacent to the juncture of the members I) and 0 thereof and in any suitable manner, but preferably by means of a bracket 12, formed integral with said stock, is a handle 13 for operating the plane. The member 0 of the stock is provided with a mouth 15, preferably formed at an angle relatively to the longitudinal axis of said member 0. Ad-

jacent to this mouth the stock 11 in the interior thereof is provided with a suitable bracket 16 for supporting the plane-iron 14: and its adjusting and clamping mechanism, which adjusting and clamping mechanism maybe, if desired,of the usual form,and hence no further descriptionthereof is deemed neccessary. This plane-iron supporting-bracket 16, however, is also disposed at an angle relatively to the stock member 0 and in parallelism with the mouth 15 of the plane, and is provided with an inclined or beveled seat 16 for the plane-iron, whereby said plane-iron 14 when in its workin position will have its knife-edge projecting through said mouth 15 at an angle to the member a of the stock, whereby one part of the work will be operate'd. upon before the other part thereof and the breaking or tearingof the fibers of the wood prevented when the plane-iron leaves the material. By means of this particular construction of plane-iron bracket the planeiro'n -can be made of the usual form and thickness, as in the ordinary planes, and whereby the necessity of making the plane-iron somewhat thicker atone than at the other side thereof in order to obtain an angular cut, as has heretofore been necessary, is obviated, and whereby also the sharpeningof the knifeed g'e ofthe iron is facilitated. V

The gaging or ad-usting means 0 for holding the m'aterialin proper an-gular position to be planed consists, in the preferred form thereof "herein shown and described, of a suitable bracket 20, pivotedto the base A, preferably at the forward end thereof adjacent to thera'ce 10, and which bracket is adapted to swing in an arc of a circle, and by the means hereinafter described support the material at any desired angle relatively 'to the race or member 0 of'the plane-stockll. This bracket 20 of the form shown is constructed ofan arm 21 and a vertical plate 22, preferablyintegrally connected at their inner ends and diverging from each other, and through the juncture of the same the pivot screw or bolt 23proj ects to pi votallysecure the bracket for -swinging movement relatively to the base A. This bracket-plate 22 is preferably provided witha curved inner end 24, whereby the, bracket-plate 22 can be swung into any desired position adjacent to. the plane-stock without the end thereof striking against the stock member 0 when the same is at the forward endof its race.

Preferably integral with and connecting the plate 2 2.and arm 21, adjacent to the outer ends thereof, is a preferably-curvedmember or arm-25, having an arc-shaped slot26 therein. M This arm preferably extends beyond the point of juncture with the member or arm 21, and is provided at its outer end with a sleeve 27, carrying a locking device held therein by any'suitable means. In the preferable form thereof the lockingcdevice consists of, a vertically-sliding bolt 28, provided with a recess (not shown.) on its side face, which a pin or screw (likewise not shown) eX tending through the wall of the sleeve at right angles to said bolt 28 intersects, whereby the locking-bolt is permitted to have a sliding movement and is prevented from being drawn out. This locking-bolt 28 is provided with a suitable actuating-handle or finger-piece 29 for manipulating the same.

The base A is provided with apertures 30, disposed in an arc of a circle similar to the arc of the slotted member 25, and in position to be engaged by the lower end of the lockingbolt 28,wher'eby on the 's'wingin g of the bracket 20 the same can be located in any desired position by pushing the locking-bolt 28, which may be a spring-operated bolt, if desired, into any one of these apertures 30.

Any number of apertures may be provided, whereby the bracket can be located at any desired angle relatively to the race or plane stock.

In order to firmly secure the gaging or adjusting means in its adjusted position and prevent the movement thereof when the plane is in use, the bracket is provided with a supplemental fastening means in the nature of a suitable clamping device 31, and which in the form shown comprises a clamping-bolt 32, having a threaded end and an enlarged head 33, and provided with a suitable actuatinghandle or sliding lever 34. The threaded end of this clamping-bolt projects through the arc-shaped slot 26 of the arm25 and enters suitable threaded apertures in the base, which apertures are likewise disposed in an arc of a circle in alignment with the locking bolt openings 30. Any desired number 'of these threaded apertures may be provided;

Intermediate of the upper face of the arm 25 and the under face of the enlarged head 33 a suitable washer 36 is disposed, whereby on the turning of ,theclamping-bolt said bracket will be clamped in the position in which the locking-bolt28 positioned the same.

The adjustable means for holding the work in position to be operatedon relatively to the plane-stop member "0 in the preferred form shown consists of a suitable fence or gage plate 40, adjustably secured to the bracketplate 22 for sliding movement to and from the movable plane. The means herein shown for securing this fence or gage plate 40 to the bracket-plate 22 comprises a suitable slot 41 in the bracket plate 22, through which a scre'wthreaded stud preferably integrally secured to the fence 40 is adapted to project. A thumb-nut 4:3 is adapted to screw onto the end of this threadedstud to clamp the adjustable fence in any desired position, a suitable washer 4.4 being disposed between the inner face'of the thumb-nut and bracketplate 22.

whe the bracket '20 is in the position shownas, for instance, in Fig. 1the adj ustable fence 40is adjusted to permit a part of its inner end, as hereinafter described, to

engage the stock member 0 of the plane and be clamped in such position, whereby the ma terial can be placed in position against such fence to permit the same to be operated on by the plane. When it is desired to change the angle of the bracket 20, the same is adjusted to any desired positionfor instance, as shown in Fig. 3-in which the bracket is shown in its adjusted position at an angle of eighty degrees relatively to the race; but in order to form a proper support to hold the material in position to be planed it is neces sary that the fence 40 be adjusted to have a part of its inner end engage the stock member 0, the same as shown in Fig. 1. Hence, by releasing the clamping device 43 and moving the fence 40 into the position shown in dotted lines (see Fig. 3) and reclamping the fastening device the fence 40 will have a part of its inner end in engagement with the stock and in proper position to support the material. By means of this improved adjustable fe nce or gage plate 40 the said fence can be adjusted to permit a part of its inner end to properly engage with the stock at whatever angle the bracket 20 may be adjusted.

If, however, the entire inner end of the fence engaged the stock member 0, the planeiron in its to-and-fro movements would strike against the edge of such fence and hack the knife-edge thereof. In order, therefore, to prevent this serious disadvantage and at the same time permit the fence 40 to be adjusted into such position relatively to the stock member that it will properly support the work in position to be operated on by the plane, in whatever position the bracket 20 may be adjusted, I provide the inner end of the fence with a projection or projecting portion 44, adapted to engage the stock member a of said plane at a point beyond the knife-edge of the plane-iron, and which in this instance is shown disposed above the upper edge of the planeiron whereby this projecting portion 44' alone engages the stock of the plane when the adjustable fence is in position to support the work, and the knife-edge in the to-and-fro movements of the plane is permitted to pass by the adjacent recessed portion of the inner end of the fence, and the injury of the same thereby obviated.

It is obvious that it is advantageous to thus cause the fence to bear against the face of the plane-stock rather than, for instance, against a fixed part of the frame, as it is possible that, owing to wear, the plane may not always occupy exactly the same position relative to any fixed point on the frame.

By means of this improved miter or bevel plane the work can be held at all times in proper position adjacent to the plane to be operated upon from any angle to which the bracket constituting a part of the gaging device is adjusted, and the liability of injuring the knife-edge of the plane also prevented.

Having thus described my invention, I claim- 1.
