Abstract

747,669. Making rubber-soled footwear. SUTTON & SON, Ltd., E., JOHNSON, J. W., and WHITTAKER, E. March 31, 1954 [April 2, 1953], No. 9218/53. Class 17 (2). All or part of the lower edge of an upper 5 for a rubber-soled shoe is perforated and such perforations 6 may be nicked as at 6a, Fig. 1. The upper on a last, with or without an insole or filler 8 of cork or felt and a sock lining 9, and with a strip 7 of unvulcanized rubber around its inner edge is then placed in the well formed between the upstanding marginal flange 11 of a rubber sole, or by a rubber strip secured to the edge of such sole, and the parts vulcanized together, in the course of which rubber flows through the perforations 6 to key the parts together. Where an insole is provided, this too may be perforated and bonded to the sole during vulcanization.
