ABSTRACT:
A chuck or coupling for connecting a rotary shaft to variable diameter work ieces; the work piece can be a pulley, shaft, bar stock or other mechanism required to be gripped by a chuck. The chuck structure comprises radially movable jaws slidably mounted on a rotary base or chuck body, together with a counter-balance for each jaw. Each counterbalance is located on a diametrical line passing through the associated jaw, whereby the jaw and counterbalance are subjected to oppositely directed radial forces during high speed rotation of the chuck structure. Centrifugal force is utilized to increase the gripping force of each jaw on the work piece.
