Abstract

747,185. Fusible cut-outs. BULGIN & CO., Ltd., A. F. Feb. 26, 1954 [April 14, 1953], No. 10214/53. Class 38 (1). [Also in Group XXXVII] Upon rise of temperature a rod 10 melts, so allowing two members 2, 3 with interengaging clawed fingers and forming part of a circuit, to spring apart. The melting of the rod 10 may be due to rise of ambient temperature or to current flowing through it.
