ABSTRACT:
A bench vise which incorporates a self locking fixed jaw operating with a pair of interlocking surfaces reacting as the fixed jaw is loaded. As the workpiece is tightened down, the jaw tends to be forced downwardly against the sliding portion of the vise to tightly lock the workpiece being held. The reaction of the load is carried directly into the support shaft for the fixed jaw, which also forms a swivel member for the vise.
