Abstract
A retract clamp apparatus is provided for supporting a work piece on a fixture. The apparatus includes a body that is secured to the support surface of the fixture, and an arm received in the bore and presenting an outer end adapted to engage the work piece. A piston within the body shifts the arm between a retracted position and an extended position, and the arm is supported for longitudinal movement with the piston and for pivotal movement about a pivot axis that is transverse to the central axis defined by the bore. The body includes structure for preventing the arm from pivoting relative to the body in the retracted position and for permitting limited pivoting of the arm about the pivot axis when the arm is shifted longitudinally a predetermined distance toward the extended position.
