ABSTRACT:
A power-actuated chuck has a chuck body provided with a plurality of chuck jaws which can be displaced radially to engage a workpiece. Centrifugal force tending to urge the jaws outwardly is counteracted by respective centrifugal weights at the ends of levers pivotally mounted upon a flange which is affixed to the back of the chuck body. Each weight has a nose which cams a respective pin axially on the body to directly or indirectly apply a radial force to the respective jaw, thereby biasing the same inwardly in accordance with the centrifugal force developed upon rotation of the chuck.
