Abstract

621,316. Fusible cut-outs. SANDERS & CO. (WEDNESBURY), Ltd., W., BAYLISS, G. H., and MANION, E. B. Feb. 18, 1947, No. 4609. [Class 38 (i)] In fuses of the type wherein the fixed contacts are covered by a shield 18, Fig. 3, provided with openings 181-184 for the fuse carrier contacts, the said openings are made of various shapes to receive correspondingly shaped carrier contacts, the shaping corresponding to different ratings of fuses. The carriers may be of the type described in Specification 601,942, having contacts as described in Specification 601,941. Figs. 4, 5 show embodiments in which one blade 17b of each pair of carrier contacts 17a has a pip 17c or tongue 17d formed thereon respectively which pass through enlargements 182a in the openings 182. Figs. 6, 7 show a contact for a different rating of fuse in which pips 17c or tongues 17d are formed on each of the blades 17b of each contact 17a, diagonally opposed to each other and passing through enlargements 183a in the openings 183. In a further type, Fig. 8, tongues 17c formed on each of the blades project in opposite directions in the planes of the blades and pass through enlargements 184a in the openings 184. If desired, the arrangements shown in Figs. 6, 7 and 8 may have pips 17c or tongues 17d, 17e adjacent each edge of each blade, the openings 183, 184 having additional enlargements 183b, 184b. A carrier having plain blade contacts may be passed through the apertures 181, the width of the blades being greater than the width of the openings 182-184 so that they could not pass therethrough.
