If desired the shoe 22 may be locked in the adjusted position about such pivot by engagement of the stud 29 with other suitably disposed holes in the bar 21.

The other cramping shoe 23 is fitted to the slides 15 of the vise for. which purpose it is formed with sockets or hollow bosses 32 fitting these slides. One or more set screws may be fitted to the hollow bosses 32 in order more firmly to secure the shoe 23 to the slides 15.

Thus the cramping bar 21 may be disposed at right angles to the faces of the vise jaws l1 and 14 with the gripping surfaces of the cram-ping shoes '22 and 23 parallel to the vise jaw faces as shown in full lines in Figure 4;. If desired, however, the cramping bar 21 may be turned to an angle with the vise aw faces while the cramping shoe 22 may be adjusted both as to position along the bar 21 and also about the axis of the screw or pin 27 for dif ferent purposes, various positions of the cramping bar 21 and shoe 22 beingindicated by dotted lines in Figure 4. r a

For cramping a rectangular frame the shoes 22 and 23 may be formed to engage the interior and exterior angles of the frame. In the modification illustrated in'Figures 6 and 7 the movable shoe 23 (provided with the socket 32 to fix the slide 15) is formed with a ledge 33 to support the frame and with abutments 34 to engage its exterior ed e. The abutments 34 are grouped along the ces'ired angle or may bereplaced by flanges extending from the ledge 33.

The relatively fixed shoe 22" is provided with abutments 35 toengage the interior angle of the frame which is indicated in chain lines in Figure 6 thus clamped between the two shoes, the abutments 35 being preferably situated above a supporting surface 36 of the shoe 22 corresponding in height to the ledge 33- and assisting that ledge in supporting the frame above the cramping bar 21.

If desired similar ledges may be provided in the shoes illustrated in Figure 4 to support the work being'cramped.

What I claim is V 1. In a woodworkers vise the combination of a fixed jaw having a plate-like gripping face'and formed with a clamping base at right angles to its gripping face and with a circular recess in the clamping base having a restricted opening leading to the rear edge thereof, the fixed jaw being also formed with a bracket extending from the lower edge of its gripping face, a clamping screw carried by the bracket, a movable jaw operated by a screw engaging a nut carried by the fixed j-aw,two parallel cylindrical slides on the movable jawfitting guides in t-hefixed jaw and passing above the clamping base, a cramping bar provided with a head fitting the recess in the clamping base and with a necklike portion narrower than and passing through the restricted opening of the recess, a cramping shoe adjustably fitted to the bar and a cooperating cramping shoe formed with sockets fitting the ends of the vise slides, substantially as specified 2. In a woo'dworkers vise the combination of a fixed jaw having a plate-like gripping face and formed with a clamping base at right angles to its gripping face and with a circularrecess in the clamping base having a restricted opening leading to the rear edge a bracket extending from the lower edge of its gripping face, a clamping screw carried by the bracket, a movable j aw operated by a screw engaging a nut carried by the fixed aw, two parallel cylindrical slides on the movable jaw fitting guidesin thefixed jaw, and passing above the clamping base, a cramping bar provided with a head fitting the recess in the clamping base and with a neck-like portion narrower than and passing through the restricted opening of the recess, a cramping shoe adjustably fitted to the bar and provided with abutmentsto engage the interior edge ofa rectangular frame and a cooperating cramping shoe formed with socketsfih ting the endsiof the vise slides, and formed with a ledge to support the frame and with abutinents to engage its exterioredge, substantially as specified.

3. In awoodworkers vise, the combination with a fixed jaw'hav ing guides and a movable jaw, of a slide on said movable aw cooperatingwith said guides, means for securing the fixed jaw to a bench with the movablejaw slide passing through the fixed jaw above the bench surface, a cramping barextending from the rear of the fixed jaw and adjustable to different angular positions with respect thereto, a cramping shoe adjustably fitted to the bar and a co-operating cramping shoe fitted to the slide of the movable jaw, substantially as specified. V

4-. In a woodworkers vise, the combination of a fixed jaw provided with guides and having a clamping base at right angles to its gripping face with a recess formed in the clamping base having a restricted opening leading to the rear edge of the base, a movable jaw, a slide on said movable jaw cooperating with said guides, a cramping bar provided with a head engagingthe recess and with a neck-like portion passing through the restricted opening, and 'co-operating cramping shoes fitted to the bar and to the movable thereof, the fixed jaw being also formed with 1 jaw slide respectively, substantially as specigripping face with a circular recess formed in the clamping base havl'n ing leadingto the rear e ge of'the baseya -niovable jaW,' a slide on saidmovalole jaw cooperating withfsaid guides, a cramping bar provided with a head fitting the'recess' and With a neck-like portion, narrower than and Y passing through the restricted opening, and co-operating cramping shoes fitted to the bar andto the movable jaw slide respectively, 7
