Abstract

921,691. Bolts. NATIONAL BANK OF DETROIT. June 22, 1961 [Sept. 13, 1960], No. 22609/61. Class 89 (1). A self-locking bolt comprises a head 7 and a shank 5 with a common geometric axis, and means providing the head with a centroid displaced from the axis so that on tightening the bolt the head is stressed asymmetrically. Slots and recesses are formed in the head to displace the centroid. In Fig. 1, in which a central recess 11 is intersected by radial slots 9, a semi-circular recess 17 in the underside of the head displaces the centroid. The recess 17 may be continued around the shank, half of the length of the recess being deeper and/or wider than the other half, Fig. 4 (not shown). The recess 11 and slots 9 may be offset from the axis, or the slots 41, Fig. 7, on one side of a mid-plane may be wider and/or deeper than those, 39, on the other, or the number of slots 41, Fig. 11, on one side of the plane may be greater than that on the other side. The slots 41 are on the same side of the plane as the semi-circular groove, or the wider and/or deeper section 47 of the groove if this surrounds the shank. If non-symmetrical slots are formed in the head, a groove need not be provided in the underside of the head, or a continuous uniform groove may be provided. Also, grooves may be formed only to the undersides of the heads.
