Abstract

1,202,978. Fusible link-operated shutters. BLOXWICH LOCK & STAMPING CO. Ltd. 19 June, 1969 [8 June, 1968; 29 Aug., 1968], Nos. 27362/68 and 41203/68. Heading A5A. A warm air register for ducted central heating comprises parallel pivoted interconnected vanes 12 mounted in a frame 11 behind a panel 10 for simultaneous movement between open and closed positions, and operated by a fusible link-actuated spring 13 carried on the frame which acts to close the vanes or maintain them closed. In one embodiment, one end 18 of torsion spring 14 mounted on spindle 15 in bracket 16 is pressed under stress into a position parallel to an upstanding lug 19 on the bracket and attached thereto by a gapped ring 21 which encircles both 19 and 18, the gap being closed by a fusible plug of a size such that on melting it permits spring end 18 to swing round and urge vanes 12 into the closed position. In the modification of Figs. 6-10, a radially-projecting loop extending from the middle of the coiled spring, and an upstanding lug on the bracket, are engaged in separate slotted members which are intersecured by fusible metal.
