Abstract

19,533. Christians, G. W. Dec. 27, 1911, [Convention date]. Fusible cut-outs.-In electric fuses of the kind in which a long fuse wire is looped to and fro between two terminals at the ends of a central insulating supporting- rod, the terminals are made in the form of caps C provided on their edges with integrally constructed hooks E supporting the loops of the continuous fuse wire F which extends between the caps lengthwise of the rod. The caps are applied to enlargements B at the ends of the rod, and the edge of each cap is cut to forms arms D. which are bent twice at right - angles and then turned back to form the hooks. The wire is enclosed by a cover composed of a filling G of plaster or other comminuted refractory material and an outer envelope H of asbestos cloth or like non - combustible fabric. The cover may be applied by first laying the cloth flat, spreading thereon a layer of plaster mixed with water followed by a layer of dry plaster, tightly wrapping the plaster-covered cloth around the fuse strip and holder, and finally securing it in place by a cord I wound around it.
