UNIVERSAL ADJUSTABLE MITER JACK AND VISE.

Specification of Letters Patent.

Patented Oct. 3, 1911.

To all whom it may concern:

Be it known that I, ANTON SHIRE, a subject of the Czar of Russia, but having declared my intention of becoming a citizen of the United States, residing at Harriman, in the county of Orange and State of New York, have invented a certain new and useful Improvement in Universal Adjustable Miter -Jacks and Vises, of which the'following is a full, clear, and exact description.

The object of this invention is to furnish a combination miter jack and vise for the use of carpenters, joiners, cabinet-makers, picture-frame makers and others, in fitting or matching pieces of wood and other material in making joints, without resorting to the use of squares or other tools to mark off a line of cut at any angle.

The invention consists of a frame provided with a fixed aw and a movable jaw between which the article is clamped; these jaws being provided with faces to guide and support the saw in making any desired cut, and the frame supplied with brackets having different faces, and facilities for attaching the device to a table or other support at different angles, all as I will proceed now more particularly to set. forth and finally claim.

In the accompanying drawings illustrating the invention in the several figures of which like parts are similarly designated, Figure 1 is a perspective view showing the device arranged to secure an inclined cut. Fig. 2 is a perspective view showing the device arranged to secure a straight out. Fig. 3 is a cross-section showing the device ar ranged as in Fig. 1. Fig. 4. is a cross-section showing the device as arranged in Fig. 2.

The device may be of wood, metal, or other suitable substance or material, and comprises a frame made up of a rail 1, having the beveled edge 2, a rail 3 having a straight edge 4, these two rails being connected at their ends and respectively rabbeted at 5 and 6. In the space separating these rails is a guide rail 7, likewise held at its ends.

8 is a jaw fastened to the frame in any suitable manner, as by screws, and having an inclined face 9 corresponding to the bevel 2 of the rail 1, and a straight face 10 corresponding to the straight face 4 of the rail 3, these

faces

9 and 10 being in the planes of their respective rail faces.

11 is a movable jaw having an inclined face 12 and a straight face 13 corresponding to the

faces

9 and 10, respectively, of the jaw 8. The invention, however, is not limited to jaws of the configuration described. The movable jaw 11 has the projections 14 which extend into the spaces between the mid-rail 7 and the top and bottom rails 1 and 3, and these projections are engaged by a plate 15 arranged upon the opposite sides of the frame and fitted in the rabbets 5 and 6; the construction being such that the movable jaw 11 may be slid longitudinally of the frame toward and from the fixed. jaw 8. One convenient means for so adjusting the movable jaw 8, consists of a screw 16 connected in any suitable way with the movable jaw so as to turn therein, and mounted in a fixed bearing 17 attached to the frame and serving as a nut for the screw, so that by rotation of the screw in the bearing 17, the jaw 11 will be moved toward and from the jaw 8, and be capable of clamping a piece of work between the two jaws and the frame.

On the back of the frame are mounted the brackets 18, and each bracket has a straight face 19 on the side next to the inclined face of the jaw, and an inclined face 20 next to the straight face of the jaw, and these faces terminate in

faces

21 and 22 respectively, which are parallel to the straight back of the frame. Each bracket is provided with a hole 23 extending therethrough at right angles to its straight face 19, and another hole 24: extending through it at right angles to its inclined face, so that the device may be arranged upon a flat face 25, such as a table or work-bench or other available horizontal surface, upon either the straight or inclined face of the brackets, and be fastened down on such table by means of screws passing through the appropriate holes. Of course, other means may be used to clamp the device upon an operating surface.

If now a piece of work be clamped between the jaws, with one edge resting upon the frame, as in Fig. 3, and a saw be laid upon the upper surface of the frame and jaws, the work may be cut on a bevel accurately, and without marking, as indicated in Figs. 1 and 3. If the device be arranged as shown in Figs. 2 and 4, the work may be cut off straight, or at right angles to its edge resting against the frame.

Obviously variations in the angle of cut may be made by appropriately shaped jaws, or by the location of the work between the aws.

The device, and especially the jaws, may be made of any material most suitable for the work for which the device is designed, and so that while capable of holding the work firmly, they will not mar it.

What I claim is 1. In a miter jack and vise, the combination of a frame, a fixed aw thereon, a movable jaw slidably mounted on the frame, the two jaws being otherwise alike and adapted to clamp a piece of work between themselves and the frame, and brackets on the frame having faces made at different angles relatively to the frame and capable of supporting the frame with its jaws reversed.

2. In a miter jack and vise, the combination of a frame, a fixed jaw thereon, a movable jaw slidably mounted on the frame, the two jaws being otherwise alike and adapted to clamp a piece of work between themselves and the frame, the faces of the aws extending at different angles relatively to the frame, and brackets on the frame having faces extending from the frame at angles the same as the faces of the jaws but in reverse position and adapted to be fixed to a supporting surface.

3. In a miter jackand vise, the combination of a frame, a fixed jaw thereon, a movable aw slidably mounted'on the frame, the two jaws being otherwise alike and adapted to clamp a piece of work between themselves and the frame, the faces of the aws-extending at different angles relatively to the frame, and brackets on the frame having faces extending from the frame at angles the same as the faces of the jaws but in reverse position and having screw holes extending through them at right angles to their respective faces to fix the device in reverse positions.

l. In a miter jack and vise, the combination of a frame, a fixed jaw thereon, a movable jaw slidably mounted on the frame, the two aws being otherwise alike-and adapted to clamp a piece of work between themselves and the frame, the jaws having faces at different angles to the frame and the edges of the frame having faces corresponding to the adjacent faces of the jaws, and brackets on the frame having faces madeat different angles relatively to the frame and capable of supporting the frame with its jaws reversed.

In testimony whereof I have hereunto set my hand this 29th day of J uly A. D. 1911.

ANTON SHIRE.
