ABSTRACT:
An improved workpiece carrier for transfer machines includes a frame, a plurality of upright support members, and a rack and pinion arrangement for adjusting the vertical position of the support members simultaneously with respect to the frame. A horizontally extending transfer bar is provided, and a plurality of carrier brackets are secured to the support member and in turn receive and support the transfer bar such as to permit free horizontal movement of the transfer bar in its long direction, while restraining movement of the transfer bar in directions perpendicular to its long direction. Affixed to the transfer bar are housing elements which include gripping devices for locating and retaining workpieces.
