Abstract
501,684. Fusible cut-outs. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and METCALF, A. W. Jan. 5, 1938, Nos. 324 and 21001. [Class 38 (i)] A fuse element consists of a silver wire or strip to which is, attached between its ends a globule of a metal or alloy having a lower melting point. In the form shown in Fig. 2, several silver wires or strips arranged in parallel are secured at their centres and ends by a globule 2 and solder 6, and are bowed outwards in between.
