Abstract

27,118. O'Brien, J. M. Nov. 25. [Cognate Application, 8000/14.] Tyres, elastic, special apparatus for making. -In the manufacture of tyre covers, the tread a is formed by extruding hard rubber compound through a suitably-shaped die on to a tray covered with french chalk, and is partially vulcanized and placed in position over the usual canvas and rubber foundation c, the sides of the tyre being built up with soft rubber b which. overlaps extensions a<1> on the part a. The parts are held together by a wrapping of fabric e, with filling-pieces f where necessary on account of the shape of the tyre, and vulcanized. The tread may comprise two or more parallel ridges separated by one or more circumferential grooves, and with curved or angular peripheries, and may be, in addition, notched transversely.
