Abstract

527,789. Punching inserts for nuts. ELASTIC STOP NUT CORPORATION. April 19, 1939, No. 11848. Convention date, April 19, 1938. [Class 31 (ii)] [Also in Group XXV] In the manufacture of nuts with elastic locking inserts 100, Fig. 8, the inserts are punched out of a strip 28, Fig. 5, by a punch 26 cooperating with successive nut blanks 58 which act as dies. Holes 92 are punched in the strip 28 by a punch 24 on the reciprocating head 20, Fig. 1, carrying the punch 26. The strip 28 is fed step by step by feed rolls 30, 32 of which the roll 30 is rotated intermittently by a pawl 50 and ratchet wheel 52 operated by a cam 39 on the punch head operating shaft 16. A cam 68 on the shaft 16 actuates, through levers 72, 74 and link 76, a slide 60 having a recess 66 which receives a nut blank 58 and positions it under the punch 26 ; the blanks are received from a groove in the inclined table 10. The nut is formed with a thread 96, while the insert is unthreaded ; the top edge 98 of the nut may be clinched over. Specification 462,150, [Group XXII], is referred to.
