Abstract
543,797. Bolts. GENERAL AIRCRAFT, Ltd., and CHILDS, A. F. Jan. 13, 1941, No. 480. [Class 89 (i)] [Also in Group XXII] Split tubular bolts are produced from a rectangular strip of metal with one or more formations or groups of formations 9 in opposite edges which interengage when the metal is bent up into tubular form. In modifications the inter-engagement may be by dove-tailed or like formations that prevent lateral as well as longitudinal displacement of the edges. One end may be expanded to act as a head or a head 13 may be screwed on and locked by expanding the end of the tube into a countersunk 14. The other end is threaded for the nut at 11. It facilitates the threading if formations are provided at this end. Tubular spacing pieces for use with the bolts may be similarly made and the bolts may be reinforced by internally fitted tubular members or rods. Specification 537,235 is referred to.
