Abstract

1,080,482. Rolling threads. ILLINIOS TOOL WORKS Inc. Aug. 4, 1964 [July 30, 1963], No. 2952/67. Divided out of 1,080,481. Heading B3M. [Also in Division F2] A screw 22 is formed with threads (18) and (20), Fig. 2 (not shown), of different heights by rolling a blank between a stationary die 12, and a reciprocating die 14, of appropriate profiles. Each die includes alternate shallow and deep grooves running obliquely across its surfaces, each of the grooves progressively decreasing in depth towards the finishing end of the die. The lower threads are finished rolled before the higher ones but are produced at a slower rate. Three or more threads of different cross-section can be formed on the screw.
