ABSTRACT:
An improved, low cost material handling apparatus adapated to grip a workpiece and move it from one place to another. The apparatus includes a pair of motion transfer devices, each of which is adapted to move a gripper in a respective direction between first and second extreme positions. One of the motion transfer devices moves the gripper in a pivotal directon. A timing mechanism is included that operates the motion transfer devices in sequence so as to move the workpiece from a home position to a work position. The mechanism also includes means for automatically moving the gripper between its gripping position and its released position when the workpiece is so transferred. By a relatively simple adjustment the sequence of operation may be reversed.
