Abstract

470,866. Fusible cut-outs. COX, C. W. March 5, 1936, No. 6625. [Class 38 (i)] In a refillable cartridge fuse, two elements are arranged in series, one of low melting point fusing on slight overloads, the other in the form of fine wires of high melting point passing through an insulating block and fusing on shortcircuit, asbestos pads being arranged to cool the arc gases. A fusible element B of solder connects the thick conductors A1, A2 in Fig. 1, while fine fuse wires in parallel passing through the refractory bock D are hard soldered at 21 to a conductor A3. Asbestos pads E1, E2, E3 cool any vapours formed when an element fuses. The pads, spacing sleeves 16, 17 arc baffle D, and the fuse elements are contained in a refractory tube 14, retained in the casing 11 by screwed end caps 12, to which the conductors are fastened by screws 13. In a modification, Fig. 3, contacts 24, 25 are provided, so shaped that the fuse may only be used one way up, thus ensuring that the lower soft solder joint 33 shall be below the arc baffle D while the hard solder joint 32 is above. In further modifications, Figs. 6 and 7, stranded end conductors A1, A2 pass through metal tubes 40 and are joined to fuse wires C1 by solder 42, the wires passing through holes arranged in a circle in the baffle D. The endcontacts 38 are U-shaped, blades 38b being connected to the wires A1, A2 and being held by the contacts 38, discs 39 and screw caps 34 'holding the contact-blades in position. Specification 443,717 is referred to.
