ABSTRACT:
The work release stop of the present invention is adapted for use with conventional types of vises for engaging and limiting the rearward movement of the adjustable jaw of the vise when releasing a workpiece clamped between the fixed jaw and the adjustable jaw to facilitate the repetitive clamping and unclamping of workpieces positioned in the vise. The work release stop acts as an adjustable stop for the adjustable jaw and includes a stop plate extending transversely of the adjustable jaw and divided into first and second parts. Gripping jaw portions extend downwardly into the guideway slot of the vise and are engageable with opposite sides to thereby maintain the stop plate in longitudinally adjusted position in the guideway. A compression spring urges the adjustable jaw in a rearward position to reduce any "play" between the adjustable jaw and the operating screw shaft.
