A power operated gripper in which both the gripping and releasing movements of the gripping elements are made under power. The gripper comprises a thrust member which is extended and retracted in a linear motion by the power means, gripper arms which swing in an arc to grip and release a workpiece, a cam and roller structure to convert the linear motion of the thrust member to arcuate movement of the gripper arms and adjusting screws which engage the walls of a V-shaped groove in the thrust member to control the extent of its movement in each direction. The parts are constructed and arranged to permit adjustment of the gripper while it is operating so that precise control of the gripping and releasing motion of the gripper arms may be attained under actual operating conditions.
