ABSTRACT:
A gripper assembly having a unitary housing with a cylinder bore and a pair of pistons slidably disposed within the cylinder bore and having a finger carrier connected to each of the pistons whereby the displacement of the pistons in one form of the invention may effect either a synchronous displacement of the finger carriers between a protracted and retracted position and which, in a slightly modified form, may effect a non-synchronous displacement of the finger carriers. In either form, the respective finger carriers are slidably supported on a trackway formed integral of the housing.
