MATERIAL HANDLING APPARATUS ABSTRACT Several embodiments of a material handling apparatus adapted to grip a workpiece and move it from one position to another position where it is released. Each apparatus includes gripping means that is moved between a released position and a gripping position and a carrier for the gripping means that is movable from a first position to a second position. Actuating means moves the gripping means to its gripping position when the positioning means move the carrier to a first position and for moving the gripping fingers to a released position when the positioning means moves the carrier to its second position. In two embodiments of the invention the apparatus includes a pair of motion transfer means, each of which is adapted to move the gripping means in a respective direction between first and second extreme positions. A timing mechanism is included that operates the motion transfer means so as to move the workpiece from a home position to a work position. The mechanism also includes means for automatically moving the gripping means between its gripping position and its released position when the workpiece is so transferred. By the addition of certain elements the path of movement of the gripping means may be altered and by a relatively simple adjustment the sequence of operation may be reversed. In one embodiment of the invention one direction of movement accomplished by one of the motion transfer means is pivotal.
