ABSTRACT:
A device for measuring forces exerted by the jaws of a chuck under both static and dynamic rotary conditions is characterized by an elongate housing and a piston in a cylinder bore in the housing and extending generally perpendicular thereto. The piston and housing are adapted to be gripped between the jaws of the chuck to pressurize a fluid in the cylinder, and the pressure of the fluid is coupled with a gauge which is moved out of an end of the housing by an amount in accordance with the pressure, and therefore in accordance with the force exerted by the jaws, and a graduated scale on the gauge provides a visual indication of the force.
