Abstract

643,306. Forging rivets. PHILLIPS, Ltd., E., and PHILLIPS, A. E. July 3, 1948, No. 17946. Drawings to Specification. [Class 83 (iv)] In a machine for cold heading and severing rivets and the like from bar stock in which lengths are severed from the stock and conveyed to a work-holding die having an ejector pin and in which the work is headed by a reciprocating punch, the ejection of the headed work is assisted by air blasts from a pump actuated in timed relationship with the ejector pin by a moving part of the machine. The pump has a non-return valve in the piston and is reciprocated by a cam which also actuates the ejector pin, the return stroke of the pump being obtained by a spring.
