ABSTRACT:
A pull bar gripper assembly having a body member with a pusher slidably mounted thereon arranged to engage the end of a workpiece to be pulled. A collar is connected to the pusher. A pair of gripper arms, each having a gripping pad connected on one end thereof, are pivotally mounted on the body member. A toggle link interconnects the other end of each gripper arm to the collar and a coil spring normally biases the pusher toward an inoperative or non-gripping position. In operation, the gripper arms are pivoted into gripping position onto a workpiece as the gripper assembly is advanced toward the workpiece by the retraction of the pusher upon engaging the end of a workpiece. In doing so, the toggle link compressing the coil spring shifts through dead center to lock the gripping pads onto the workpiece. Release is effected by pulling the gripper assembly away from the workpiece slightly, causing the coil spring to return the pusher and gripper arms to their normal inoperative or non-gripping position.
