Abstract

1,183,821. Making lock nuts; rolling. R. E. HAYDEN. 18 April, 1967 [18 April, 1966; 25 Nov., 1966], Nos. 16866/66 and 52816/66. Headings B3A and B3M. [Also in Division F2] A method of making a self-locking nut 10A comprises machining a circumferential groove either in the external surface of the nut or in a boss at one end thereof to produce a neck portion of reduced radial wall thickness, the neck portion being stretched axially by rolling the nut between the tapered edge 16 of a roller 15 and a corresponding arcuate concave edge 26 of a quadrant 25, the edges 16, 26 being oversize with respect to the groove in the nut 10A to produce the desired stretching of the neck portion. A manual crank 19 is provided for rotating the roller 15, which is journalled on a shaft 6, and the quadrant 25 is adjustable towards and away from the roller 15 by means of elongated slots in the quadrant and cooperating bolts.
