Abstract

642,203. Moulding whistling toys. PLAYLASTIC TOY CO., Ltd., and SIMON, F. H. March 3, 1948, No. 6614. [Class 87 (ii)] A hollow, moulded rubber article, e.g. a doll, having a whistle formed integrally therewith is made by assembling between two unvulcanized rubber patches 6, 7, Fig. 1, a forming member, preferably of metal, having a body portion 2 and two shanks 3, 4 adapted to form a whistle cavity, one of the shanks having an endless cutting edge 5 and the patches having holes through which extend the shanks, placing the assembly on the inside of one of two unvulcanized rubber sheets 10, 11 adapted to form the walls of the article with the cutting edge in contact with the rubber sheet, moulding the rubber sheets in a heated mould whilst they are subject to internal pressure to shape the sheets and to force the cutting edge through the adjacent sheet, Fig. 2, and then removing the forming member through the hole thus made. Articles may be continuously manufactured by feeding metal members 2 complete with rubber patches between two sheets of rubber which are fed into an automatic machine which stamps and then moulds the article with the aid of an inflating medium.
