ABSTRACT:
A vise for clamping two works comprising a vise body having a groove of T-shaped section and first and second reference surfaces perpendicular to the groove; a pair of movable members fitted in said T-shaped groove between said first and second reference surfaces, having clamping surfaces opposed to said reference surfaces, respectively, and provided at the rear sides opposite to said clamping surfaces with inclined surfaces inclined to converge toward the T-shaped groove; a wedge fitted between said inclined surfaces; a block slidably and disengageably fitted in the T-shaped groove between said movable members; and a bolt connecting said wedge and the block for forcing the wedge toward the block. The second reference surface is disposed on a supporting member which carries an inclined third reference surface. By removing a movable member and reversing the supporting member, the third reference surface opposes the first reference surface for clamping a single work therebetween.
