Abstract: A power press in which low inertia motors with speed control circuitry are connected to a cam which acts upon a lever or cam follower which, in turn, cooperates with a force-storing element which has a spring action and is coupled, e.g. by the same lever, to the tool of the press. Accordingly, in the rotation of the cam, the force-storing means stores potential energy which is transformed into kinetic energy of the ram in another region of the cam at which part of the energy can be delivered to the low inertia motors. Hence the speed control of the motor will, in part, regulate the rate at which the stored force is delivered to the workpiece.

Abstract: A pair of hydraulic stabilizing cylinders are supported on a common frame parallel to the main pneumatic drive cylinders driving counter-blow hammer impellers. The stabilizing piston within each stabilizing cylinder is connected to its adjacent impeller. Those ends of the respective stabilizing cylinders adjacent the impeller are connected to the opposite ends of the other stabilizing cylinders by fluid filled hydraulic lines. Because the cylinders and pistons are the same size, as the impellers move, fluid is transferred from one end of each cylinder to the other end of the other. However, should the impellers not move in synchronism toward their point of impact, that impeller tending to move ahead of the other will experience resistance from the fluid in the stabilizing system which tends to keep the impellers in step. In addition, means is provided to detect differences in position of the synchronizing pistons.
