SPECIFICATION forming part of Letters Patent No. 504,856, dated September 12, 1893.

Application filed May 2, 1893. Serial No. 472,807- (No model.)

To aZZ whom t may concern:

Be it known that I, JOHANN AICHNER, a citizen of Germany, and a resident of the city of Brooklyn, in the county of Kings, State of New York, have invented certain new and .useful Improvements in Carpenters Vises,of

which the following is a specification.

The object of my invention is to provide a new and improved carpenters vise for holding pieces of wood while planing their ends, either at right-angles to `the edges or at an obtuse or acute angle.

The invention'consists in the combination with a fixed jaw, of guide-bars secured to the same, a movable jaw mounted on said guidebars, means for moving said movable jaw, a beveled piece mounted to move on the guidebars and to pass into a recess in the fixed jaw and means for coupling said beveled piece to the movable jaw.

The invention also consists in the construc tion and combination of parts and details, which will be fully described hereinafter and Iinally pointed out in the claims.

In the accompanying drawings, Figure 1 is a front-view of my improved carpenters vise. Fig. 2 is an end-view of the same. Fig. 3 is a plan-view, with the beveled piece drawn out. Fig. 4 is a transverse sectional view, on the line l 4, of Fig. 3. Fig. 5 is a plan View, the beveled piece being within thefixed jaw. Fig. 6 is a transverse sectional view, on the line 6 6, of Fig. 5, and Fig. 7 is a transverse sectional view, on the line 7 7, of Fig. l, showing the vise reversed.

Similar letters of lreference indicate correspending parts.

The vise is constructed with the fixed jaw A and the movable jaw B. To the rear of the fixed jaw A two guide-bars C are fastened, which are L-shaped in cross-section and which are connected at the ends opposite the ones fastened to the jaw A by a cross-piece D. A brace-bar E is fastened to the cross-piece D and to the back of the fixed jaw. The movable jaw B is suitably guided on the guidebars C. The fixed jaw A is provided in its inner side with a triangular recess a, shown in dotted lines in Figs. 3 and 5 and in full lines in Figs. 4 and 6. A sliding triangular or beveled piece H of the same height as the jaws A and B is arranged between the same and is of such size and such depth thatit can pass into the recess a and fit snugly in the same. Said beveled piece H is provided with an extension F passing through the slot between the guide-bars C, on which extension a cross-piece F is formed, for the purpose of guiding said beveled piece H on the guidebars C. A spring catch .I is fastened on the back of the beveled piece H and is adapted to engage a pin K projecting from the back of the movable jaw B. A screw-spindle L provided with a crank-handle M is mounted to turn in a bearing N on the cross-piece D,which spindle L is screwed through a nut O on the end of the jaw B and can pass into an aperture P in said jaw B, as shown in dotted lines in Fig. 3. The tops of the jaws A and B are at right-angles to the front of the jaws, as shown at b, Fig. 2, and the bottom of the jaws is at an angle of twenty-two and one-half degrees to the front of the jaws, as shown at d, Fig. 2. The two sides of the beveled pieceH are at right-angles to each other and each at an angle of forty-five degrees to a plane parallel with the front of the jaws.

The device is used in the following manner: r1`he same is clamped to an ordinary carpenters work-bench in such a manner that the top fm is parallel with thetop of the bench. If a bevel of forty-five degrees is to be cut, the movable jaw B is moved a greater or less distance from the fixed jaw, to permit of inserting the piece to be cut, which piece rests on the top of the beveled piece H. The projecting part is then planed off flush with the surface m. If the piece is to be cut 0E at right-angles, the movable jaw B is moved against the jaw A and the spring-catch J is raised so as to disengage it from the pin K, whereby the beveled piece H is unlocked from the movable Ajaw B. If now the jaw B is moved from the jaw Athe beveled piece H remains in the recess@ of the fixed jaw A, as shown in Fig. 6, and the piece to be cut o can be placed between the jaws A and B. The piece can then be cut 0E at right-angles by planing along the tops fm of the jaws. In order to cut bevels of twenty-two and one-half IOO degrees and sixty-seven and one-half degrees,

twenty-two and one-half degrees isdesired, the beveled-piece H remains in the recess a of the fixed jaw A and the board is clamped between the fixed and movable jaws and is cut 0E along the inclined face 0 of the vise, which is at an angle of twenty-two and onehalf degrees to the front of the jaws C. In ease the piece is to be cnt at an angle of sixtyseven and one-half degrees, the beveled piece H is locked to the movable jaw B so as to be Withdrawn from the recess a. The board to be cut at an angle of sixty-seven and one-half degrees is then placed on the upper surface of the beveled piece H and `the projecting part is cut oft' Hush with the inclined face a of fthe-jaws A and B.

`Having` thusl described myfinvention, I claim las new. and desire to secure by Letters Patentlll. InY ay carpenters vise,l the combination with a fixed jaw, of guide-bars secured to the same, amovable jaw mounted to slide on said guide-tracks, and means for. moving said movable jaw, one surface of said jaws being` at lright-angl es to the fronts of the jaws and the other face at an an gle of twenty-two and onetWentieth-f degrees, and a beveled movable piece mounted on the guide-bars, substanwith a recess, of guide-bars secured to said fixed jaw, a'movablejaw on said guide-bars, means for moving said jaw, a beveled piece mounted to travel onlsaid. guide-bars and-to pass into -the `rece'ss in the xed` jawy and ymeans for coupling said: beveledpiece to the movable jaw, substantially as:set-fortht In testimony that I claim the foregoing as my invention Ihave signed mynarne in presence of'two subscribing witnesses.
