Application January 20, 1942, Serial No. 427,475 Y (c1. si-zcij 3 Claims.

TheA present invention is especially adapted for machine work, that is, securing the work on the table of a machine tool. It permits a ready adjustment for all lengths of material, even to the full extent of length of the table, a very powerful vise setting mechanism, and clearance for the operation of the machine tools over it.

Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a plan View of the vise.

Fig. 2 a side elevation.

Fig. 3 a section on the line 3--3 in Fig. 1.

Fig. 4 a perspective View of the movable jaw.

Fig. 5 a perspective view of a wedge block.

Fig. 6 a perspective view of an abutment for the wedge block.

Fig. 7 a section on the line 'I-I in Fig. 2 showing the adjustment perforations. f

I marks a machine bed. This has the usual undercut slots 2. A fixed vise jaw 3 has an extending securing plate 4. Bolts 5 having their heads in the slots 2 of the machine extend through perforations in the extension 4 and permit Aof the clamping of the fixed jaw at any place along the table of the tool.

In order to keep the jaw square with the tool, a key 6 is provided which extends into one of the grooves of the tool table and thus maintains the jaw at right angles to the grooves 2.

A movable jaw 'I has a jaw face opposing the fixed jaw. It has a wedged face 8 facing rearwardly, and a flange 9 at the bottom of the movable jaw. An abutment I I) has a taper or inclined face Ia opposing the face 8. The faces 8 and I0 are preferably both inclined, but these faces are not in merging planes. The abutment is provided with an extension II and bolts I2 having their heads in the grooves 2 extend through perforations in this extension and the bolts clamp the abutment in any position to which it may be adjusted. l

A wedge block I3 is arranged between the faces 8 and Illa. It is provided with a screw threaded opening I3a in which is arranged a screw I4. The screw I 4 seats on the flange 9. The screw is provided with a head I5 which operates in an enlarged opening I6 extending downwardly from the top of the wedge block. The heads I5 have wrench sockets |511 by means of which the bolts may be set up.

It will be noted that the screw operating on the flange has no tendency to raise the movable jawby reason of the wedging action at the front of the block. It will also -be noted that as the wedging action moves upwardly along the surface Ilia, the tendency is to force the wedge block downwardly. The net result is a firmly seated movable jaw.

It is desirable to have definite adjustments for the movable jaw so that they may be adjusted prior to the introduction of the piece, or may be adjusted leaving a margin for the setting up of the wedge block. Further, it is desirable to positively lock the -abutment and fixed jaw together so that there can be no slipping of the clamps. This is accomplished in the present invention as follows:

Bars Il are provided with two series of holes I8 and I9, the series I8 being opposite the fixed jaw and the series I9 opposite the abutment. These holes are preferably spaced one inch apart. The adjacent holes of the series are such that when used, the jaws are brought into immediate contact so that the other holes lead to adjustments away from this position.

The fixed jaw is provided with openings 20. These openings preferably vary from the spacing of the openings I8. As shown, the holes 20 are spaced e of an inch apart. A series of holes 2I are arranged in the abutment. These holes are preferably 'V8 of'an inch apart. Pins 22 are adapted to be inserted in the holes when the desired holes are brought into register.

It will be noted that the inch spacing in the bars permits the operation of the jaws to approximately the opening desired. Where fractions of an inch are desired, an opening in the bar is brought into register with an opening in the abutment having the fractional difference desired. That is to say, there is a step up of 1/8 of an inch adjustment with each pair of openings in the bar and abutment so that any fraction in eighths may be accomplished by bringing the proper openings in register.

If a finer adjustment, as 11e of an inch or less, is desired, the variation may be accomplished by using one or the other of the openings 20, as the change of the openings 20 with relation to the openings I8 brings a variation of Tie of an inch. Any gradation desired may be accomplished in this manner. On the other hand, the spacing of the pins gives ample metal for strength and the adjustment may be Very simply fixed'jaw mounted on the frame, a movable jaw carried by the frame and movable with relation tothe fixed jaw,.said jaws having parallel op-v posing faces adapted to receive a work piece,'a
