Abstract

538,852. Soles for footwear. SPERRY, P. A. Feb. 17, 1940, No. 3066. [Class 17 (ii)] [Also in Group V] A non-slip shoe sole is made by moulding a vulcanizable rubber composition in an arcuate mould having ziz-zag wedge-shaped fins to produce a shape, Fig. 3, such that on flattening the sole the gaps 17, formed by the mould fins, are closed. Fig. 4 shows the flattened sole. The rubber composition may be vulcanized in the mould or partly vulcanized in the mould and further vulcanized after the sole has been flattened. Specification 538,851, [Group VIII], is referred to.
