ABSTRACT:
A stock lifter for progressive dies in the form of a fixedly mounted fluid cylinder designed to be charged with gas at a desired pressure. A piston within the cylinder has a piston rod projecting upwardly from within the cylinder so that its upper end is adapted to lift the stock when the downward pressure on the stock is relieved so that the piston is at all times biased upwardly. The cross sectional area of the lower side of the piston is substantially greater than the upper side of the piston and the portions of the cylinder above and below the piston are in free communication.
