Abstract

561,439. Repairing pneumatic tyre covers. SIMON, Ltd., H., and CALVERT, G. W. Jan. 15, 1943, No. 802. [Class 144 (i)] [Also in Group V] A pneumatic tyre cover b is repaired with reinforced unvulcanized rubber a cured by a partly or wholly heated ring e of flat internal surface and of diameter slightly less than the tyre when inflated so that when the inner tube is inflated the flat ring maintains the tread surface flat. The ring e may be hollow or have annular tubes for steam around its periphery or may be heated by resistance wire or a heated pad. The ring may be split transversely to allow of overlapping the ends for diametrical adjustment. For large tyres, the ring may be split circumferentially in rings fitted to the tyre and then bolted together.
