Abstract: An apparatus for increasing the force exerted by a hydraulic press. A pair of headers are mounted on the upper platen of the press and rods extend downwardly from each header and carry blocks that are adapted to be received within pockets in the lower platen. When the upper platen is lowered toward the lower platen and the cooperating dies carried by the platens engage the workpiece, the blocks are automatically locked within the pockets to integrally connect the headers to the lower platen. Auxilliary cylinders mounted on the upper platen exert an upward force against the headers forcing the headers upwardly and thereby increasing the force applied to the workpiece.

Abstract: A motion transfer system for conveying a carried unit, such as a shelf in a chain driven conveyor, about a curvilinear path of movement while maintaining the carried unit in a firmly gripped, fixed position with respect to a reference plane, such as the horizontal, during the linear and curvilinear movements.
