Abstract
561,453. Self-locking nuts. DUNDAS, Ltd., R. K., KING, R. D., and WOOD, N. F. Dec. 15, 1942, Nos. 20957 and 20958 /43. Divided out of 561,286. [Class 89 (i)] [Also in Group XXII] Self-locking nuts of the kind described in Specification 561,286 are provided with curved instead of plane slots. The slots 2a, Fig. 1, may be straight in the direction transverse to the figure, or may be curved in both directions. The slots may be-concave upwardly instead of convex as shown or one slot may be concave upwardly and the other convex. The extent to which the slots extend across the nut may be varied. The cut may start at the end of nut at w, Fig. 11, and end at t. Instead of overlapping slots two slots may be cut at the same level but not extending as far as the axis. The cut parts of the nut are deformed either axially or laterally. The extension 1a of the nut may be slightly coned and at its base may be of the maximum possible diameter to obtain a complete circular cross-section. The cuts may be formed directly in the hexagonal stock without any turning down of the end. More than two cuts may be employed. The slots may be cut by a thin circular saw which runs between guide rollers whereby it is caused to move in a curved or bent path. According to the first Provisional Specification the reduced end portion can be made of hardened steel and be secured'subsequently to the main body of the nut which may be wholly or in part non- metallic. Specification 551,534 also is referred to.
