Abstract
493,587. Bolts. HARMON, R. E. Jan. 5, 1938, No. 308. Convention date, Jan. 6, 1937. [Class 89 (i)] A bolt, particularly suitable for securing a wooden beam to a steel girder, comprises a body 2 having at one end a head 3 and at the other end means for securing it in place on the work, the body being provided or formed integrally with one or more fins 7, one or more of which have their outer faces 11 lying in a plane a-a substantially tangential to the periphery of the body 2, so as to prevent rotation in both directions. The head 3 may be hook-shaped with a flat face 4 substantially at right-angles to the axis of the body 3, the securing means may comprise threads 5 and a nut 6, and the plane a-a is preferably disposed at right angles to the medial plane of the head 3. The outer edges of the fins may be made thin, and the ends of the fins may merge into the body 2 of the bolt. Fig. 3 shows two pairs of parallel fins 7, 7 and 8, 8, while Fig. 4 shows one pair 7, 7 combined with a radial fin 15.
