eferable form isshown in Fig. 1, where A is a shell composedof two halves, a, one of which is shown in Fig. 502. This shell is made slightly tapering at theends, and with a slight inward tiange, so asto grasp firmly the wire B B. The two halves are placed so as to form acomplete cylinder, the ends grasping the wire 55B B, and the hoops or bands E E slipped on. This arrangement forms a shell or case forthe safety-wire, and at the same time relievesit of tensile strain, the strain of the wire B Bbeing carried by the case. 60 What I claim is— 1. The combination, with the safety wire ordevice, of an inclosing case or shell, substan-tially as set forth. 2. The combination, with the safety-wire 65and main severed conductor, of a shell or caseinclosing the safety device or wire and reliev-ing it from strain, substantially as set forth.
