Abstract

1300136 Fusible cut-outs BRUSH ELECTRICAL ENG CO Ltd 19 April 1971 [6 March 1970] 10766/70 Heading H2G A fuse element comprises a metallic strip which has a series of sloping sided notches 2 cut in one edge and a series of tongues 4, identical in size and shape to the notches, formed in the opposite edge such that they are positioned opposite the notches and form therewith a series of necks 6<SP>1</SP>. The fuse elements are stamped from sheet metal by using a stamping tool of suitable profile, the cutting operation being performed by stamping the notches 2 in a straight edged piece of metal, moving the stamping tool and sheet relative to each other a distance A<SP>1</SP> corresponding to the required width of strip, and then performing a second stamping operation with the same tool which cuts the strip from the sheet and forms the tongues on the second edge, at the same time forming the notched edge of the next element. For a given dimension of notch, the size and shape of the necks 6<SP>1</SP> can be altered by altering the feeding distance between stamping operations i.e., by changing the strip width.
