Abstract

544,430. Fusible cut-outs. SEVITT, A. A. Jan. 9, 1941, No. 337. Convention date, April 11, 1940. [Class 38 (i)] A cartridge fuse has removable end caps so that both the fuse wire and an indicatory wire can be renewed. A porcelain or glass body 1 has reduced tapered ends 1a on which are secured by friction or adhesive rings 2 of flat, L-shaped or U-shaped crosssection. The caps 4, 5 are attached to the rings by projections 3 and recesses 6 in the form of partial screw threads, or by annular projections and recesses if the cap is slit to make it resilient. In this case the projections and recesses might be dispensed with. The fuse wire 10 and an indicator wire 11 are held between the ring and cap and may lie in grooves in the ring. The upper cap 4 is recessed at 7 to receive the indicator button 12, and the lower cap has a projection 9 of a size to correspond with a fuse holder of a given rating.
