Abstract
1324549 Self-locking castle nut AMERACE ESNA CORP 8 Dec 1970 [9 Dec 1969] 58287/70 Heading F2H In a self-locking one-piece metal castle nut 10 comprising a thin-walled, internally threaded tubular body 12 provided with wrenching faces 26, the thread 14 extending the length of the body, a radially outwardly projecting flange 20 at one end 16 of the body and preferably of an axial depth sufficient to encompass at least one full turn of thread, and at least one pair of axially extending diametrically opposed slots 30 in the body wall adapted to receive a cotter pin, portions 36 of the body, located axially between the flange and the end 32 of at least one slot, are permanently deformed radially inwardly with respect to, and are thinner walled than, adjacent surrounding portions of the body 12 to provide thread portions 38 such that when the nut is threaded on to a bolt the deformed portions 36 are resiliently deflected outwardly to grip and lock the nut and bolt together. The portions 36 are preferably not diametrically opposed since if an end of a diametral hole, for receiving a cotter pin, of a coacting bolt, engages a portion 36, the locking effect is lost. In the embodiment of Figs. 4-6 (not shown), the nut (110) has deformed portions (136) which are circumferentially extended to be wider than the slots (130) to minimize this reduction in locking effect so that the applied installation torque is more nearly constant. In Figs. 7 and 8 (not shown) a “double hexagon” headed nut has deformed portions (236) located beneath projections (234) rather than beneath slots (230).
