Abstract
229,166. Rapson, F. L. June 17, 1924. Tread surfaces.-Relates to tyres of the kind provided with a plurality of superposed treads arranged so that as one wears away the next will automatically become effective, and consists of forming the tread with grooves of non- uniform depth. In the construction described, the tread consists of two circumferential grooves d, Fig. 1, providing a continuous rib b and transverse grooves e forming a series of blocks c on each side of the rib b. The grooves d, e are formed with parts g, i of increased depth, leaving connecting pieces f, h at the corners of the lateral series of blocks, so that when the original tread surface wears away, another surface shown in Fig. 4 becomes visible. In a modification, the mould for forming the tread may be adapted to provide bridge-pieces at the centres of the grooves j. The sides of the tread may have ribs m, n of V. and semi-circular shape and of decreasing size.
