Abstract

485,401. Moulding tyres. DUNLOP RUBBER CO., Ltd., and BROADBENT, F. G. Dec. 17, 1936, No. 34670. [Class 87 (ii)] Relates to machines in which a flat tyre casing 20 is expanded into tyre shape 21 by plates 19. The plates are mounted on links 16 pivoted to intergeared links 12, 13. The links 12, 13 are pivoted to a sleeve 6 secured to an extension 1 of a piston rod, and to a fixed sleeve 7 through which the rod 1 passes. The links 12, 13 are guided at their outer ends between wings 24 extending radially from the sleeves 6, 7. A telescopic or other tube 27 on the rod 1 limits the expansion of the tyre shape.
