Abstract
A clamp effort intensifier that multiplies the manual effort used for clamping vise jaws onto a workpiece through the use of a cam that actuates the vise jaws together to provide adequate clamping forces while substantially reducing the manual effort necessary to achieve a safe clamp force. The effort intensifier acts to load the vise jaw through a heavy spring which deflects as the jaws are loaded. The amount of deflection can be used to indicate the clamping force exerted on the jaws. An interlock to the machine tool used will prevent operation of the tool until the clamp force exceeds a desired level.
