A mechanism for loading workpieces into and/or unloading workpieces from a stamping press has a workpiece carrying arm and includes a drive mechanism for reciprocating the arm horizontally through a desired stroke and for reciprocating the arm vertically adjacent the opposite ends of its stroke. The drive mechanism comprises a crank for shifting the arm horizontally and a second crank for shifting the arm vertically. The cranks are operated sequentially and in timed relation by a pair of Geneva wheels driven by a motor-operated program wheel.

DETAILED DESCRIPTION The primary object of the present invention resides in the provision of a workpiece handling device of the type described which is of relatively simple and economical construction.
At the same time, the device of the present invention is designed to be operated mechanically by means of an electric motor to produce reliable operation over extended periods of time.
The preferred embodiment of the work handling device of the present invention comprises a workpiece transfer arm which is operated by a conventional Scott-Russell linkage for movement in a horizontal path, the arm being mounted on a vertically reciprocating slide to impart vertical displacement to the arm adjacent each end of its horizontal stroke.
Timing of the horizontal and vertical displacements of the arm to obtain smooth operation of the device is achieved through the use of two Geneva wheels operated intermittently in timed sequence by a single rotary driver.
