Abstract
A wide range wheel chuck in which three wheel engaging chucks are disposed on the ends of three lever arms. The lever arms are rotatably journaled at the other end to a stationary base and at a point intermediate their ends to a base that is rotatable with respect to the stationary base. Relative movement between the bases results in simultaneous equal radial motion of the chuck jaws at the first ends of the lever arms.
