Abstract

963,392. Protecting aircraft tyres. DUNLOP RUBBER CO. Ltd. Jan. 10, 1961 [Jan. 26, 1960], No. 2742/60. Heading B7C. Tubeless aircraft-wheel tyres are protected from blow-out under braking heat by means of a bush 4 sealed to a hole in the wheel rim base 2 and containing a slidable plunger 11 which is air-tightly sealed in the bush by a rubber disc 12 and is retained therein by a plug 8 of fusible metal designed to melt rapidly at a predetermined temperature, preferably slightly higher than that likely to cause tyre failure, so that the plunger 11 is expelled from the bush by the inflation pressure of the tyre, taking with it the portion of the plug 8 blocking the bush passage, to deflate the tyre. As shown, the bush has a hexagon head 5 and a screw-threaded shank to screw into the rim base from outside the tyre. The bush is bored to provide intercommunicating axial bores 6, 7 of different diameters, the larger bore 7 nearer the head 5 being screw-threaded to receive the fusible metal plug 8 and the smaller bore 6 housing the plunger 11 sealed therein by the disc 12. In alternative arrangements the bush head 5 may be adjacent the smaller plunger-housing bore 6, the bush being screwed into the rim with the head inside the tyre space, or the fusible plug may take the form of a rod passing through holes in the plunger 11 and bush wall, or the form of a circlip engaging a necked portion of the plunger and a step in the bush bore. Alternatively, the fusible plug may be slidably retained in the larger bore by a member force-fitted therewithin.
