Abstract

280,669. Killen, E. B. Sept. 17, 1926. Grant of Patent revoked. Tread projections and surfaces; jackets and covers of special crosssection. - The curved tread portions of widesection low-pressure pneumatic tyres, such as those described in Specifications 209,123 and 235,971, are formed with traction projections and one or more endless ribs between the centre line and each extreme edge of the tread, with tread or other rubber reinforcements between the ribs and the widest part of the tyre cover. In some cases, a similar rib may also be provided along the centre line of the tread. Fig. 5 shows a plan of one form of tread comprising endless ribs 1-6-1 separated by deep grooves 2 spaced buttresses 5 being provided at the edges of the tread. Fig. 11 shows a plan of a non-skid tread of the kind described in the prior Specifications above referred to, and Figs. 12 and 13 show in plan and section respectively the present modified construction in which endless ribs 4-3-1 are now provided in such treads. In further modifications, the tread ribs are formed of zig-zag shapes; and one or more reinforcing ribs may. be provided between the kerb-protecting ribs 8 and the extreme edges of the tread.
