Abstract

146,337. Goodyear Tire & Rubber Co., (Assignees of Wattleworth, C.). Aug. 17, 1917, [Convention date]. Vulcanizing - chambers.-India-rubber articles, particularly tyres, are vulcanized by conveying moulds containing them through an oven, the time and temperature being adjusted so that the vulcanization is completed during their passage. A conveyer 8, Fig. 1, comprising wheels 10 with depending hooks 12, runs on rails 9, the hooks 12 passing through a slot 17, Fig. 2, into a vulcanizing chamber 5 which may be lined with firebrick and heated by jets of gas directed through tuyeres 20 on to refractory material 19. The moulds are slid on to a tilting table 32 which tips them into a saddle 34 whence they are picked up by the advancing hook and carried through the chamber to a second table 35 which tilts over flush with a receiving table 36. In a modification, the conveyer 24, Fig. 4, is enclosed entirely in the chamber and is provided with saddles 23. The mould is slid through a flap 30 on to a tipping table 37 released by trip-gear 39 operated when a saddle 23 comes into position. At the delivery end, the mould slides out of the saddle down a shoot through a second flap 30.
