Abstract
A fluid pressure actuated clamp or gripper includes a mechanism housing mounted upon and projecting forwardly from the front end of the fluid pressure motor housing to define a passage loosely enclosing the projecting portion of the piston rod of the motor. The mechanism housing is split from front to rear into two separable halves and aligned bores through the housing halves detachably receive the opposite ends of a pivot pin upon which elements of the clamp or gripper mechanisms are mounted. A carrier fixedly mounted on the piston rod within the mechanism housing passage detachably mounts resilient bumper members engageable with the front end wall of the motor housing to define a resiliently cushioned rearward end limit of movement of the piston rod.
