ABSTRACT:
A jaw assembly for use with a work arm to move workpieces from one station to another is disclosed. The jaw assembly is operable to grip and release workpieces and comprises jaw elements arranged in a uniform pattern about the axis of the jaw assembly which are displaced radially to grip and release workpieces. The actuator comprises a fluid power operated rod coaxial with the axis of the jaw assembly. The rod is operatively coupled with each jaw element by means of a corresponding crank. A pair of flat yieldably resilient strips are cooperative with the crank and the jaw element so as to maintain the jaw element in a predetermined relationship as it moves radially. In the preferred embodiment, this predetermined relationship is a vertical orientation of the work gripping surface of the jaw element, the same as the axis of the jaw assembly which is also vertical.
