ABSTRACT:
A vise for clamping workpieces of different sizes, and including two adjustable pieces, one of which gives a large adjustment and the other which gives a finer adjustment. A clamping jaw is included, and the adjustment pieces can be set so that there is desired clearance between the jaw and the workpiece prior to applying hydraulic force in the clamping action. Rotation restrictors apply to each of the rotationally adjustable members, and a spring returns the jaw to the unclamped or opened position.
