Abstract

226,030. Gaisman, L. Dec. 7, 1923. Moulding indiarubber and boots and shoes.- Concavo-convex rubber heels and soles are formed by inserting a partially-vulcanized flat blank a, Fig. 2, into a ring or frame mould b, Fig. 7, of similar contour but smaller dimensions than the blank, causing the blank to arch. and completing the vulcanization therein. The moulds b are preferably of sufficient depth to permit of stacking in the vulcanizer. A block c, fitting the frame b and formed with a convex top, may be employed to facilitate positioning of the blank a. Any desired pattern or holes for washers, screws &c. are imparted to the flat blank during the partial vulcanization.
