Abstract

548,535. Making hollow rivets &c. GOODMAN, Ltd., G., and GOODMAN, G. B. April 10, 1941, No. 4763. [Classes 83 (ii) and 83 (iv)] Hollow rivets or sockets are made from headless slugs in a die 11, Fig. 3 (Prov.) fitted with an ejector 20. The top die 28 carries the punch 21 that is to shunt and pass entirely through the blank, and is recessed at 23 to receive the metal displaced by the punch to form the head. The bottom of the rivet is punched out in a second die with a hollow ejector. The ejector may be mounted in a cross head 35, Fig. 5 (Prov.) being fitted with a guiding flange 40. At the end of the upstroke of the press head 28 sleeves 30 engage the heads of long bolts 36, screwed in the crosshead, to actuate the ejector. The punch is lubricated by a horseshoe-shaped pad 55, Fig. 2 (Complete) mounted in a bath of lubricant 54 carried by an arm 52 urged by a spring 46 into position to surround the punch. On the down stroke of the press a cam 50 acts on a pin 49 to swing the lubricator aside.
