Abstract
552,726. Inner tubes for inflatable objects. FIRESTONE TIRE & RUBBER CO. Oct. 17, 1941, No. 13408. Convention date, Feb. 21. [Class 144 (ii)] A puncture-sealing inner tube for a pneumatic tyre or other inflatable object comprises a peripheral wall embodying circumferential corrugations crossed at least partially by a chain of protuberances, and a continuous tacky but normally non-flowing sealing layer on the inner surface of the wall beneath the tread. As shown, the inner tube is formed with circumferential corrugations 2 containing spirally arranged ribs 4 extending partially or completely around the tube. When the tube is inflated within its cover, the corrugations disappear, the rubber being placed under compression so as to seal up small punctures. The presence of the ribs 4 assists in venting air from between the tube and its cover during inflation and also in venting the tube during the moulding operation incident to vulcanization. The tube is rendered effective against larger punctures by a lining of sealing rubber 6 covering the whole of the interior or only the portion adjacent the tread. The inflation valve is provided with a tubular rubber extension 8 passing through the sealing layer.
