<p>917,323. Electric cables. SHIELDS, H. F. H. Nov. 23, 1961 [Dec. 29, 1960], No. 44627/60. Class 36. [Also in Group XXV] A power transmission cable, Fig. 6, comprises an inner wire or strand 52, a plurality of outer wires or strands 53, all of circular section, and a number of locking-elements 54, 55, each locking element having an arm passing radially between two of the outer wires or strands 53 and hooking over the inner wire or strand 52 and having an outer portion shaped to extend at least partly over said two of the outer wires or strands to lock these two wires or strands to the inner wire or strand. The locking elements may be spaced apart along the length of the cable but in Fig. 2 they are shown abutting in end-to-end relationship, only the outer portions of the locking elements being visible in the assembled cable. Fig. 3 illustrates a locking element in side elevation. In Fig. 6 the outer portions of the locking elements 54 are formed with flattened faces that rest on spaced supports 50. One or more of the wires or strands may be of a material of high tensile strength to take the tensile load. The locking elements 54, 55 may be of plastic material, for example polyvinyl chloride or nylon, or of metal, for example a light alloy.</p> |
