Abstract
246,363. Kent, W. J. May 20, 1925. Moulding boots and shoes.-Rubber and composition heel pads with inset metal washers B are characterized by integral tie portions C of very thin metal which serve merely to hold the washers while being placed in position on pins I in a mould F. Usually 36 or other convenient number of heel cavities are formed in a plate G. Fig. 1, and the plate F is formed with as many pins I projecting into each cavity as washers. The washers are placed on the pins and heel blanks A<1> are partly inserted into the cavities and a follower H laid on. The multiple mould and contents are then heated in a vulcanizing press and the follower H is pressed down. While one mould is undergoing heat treatment another is being prepared. Specifications 11134/04. [Class 17, Boots &c.], and 142,731, [Class 17 (iii), Boots and Shoes, Protectors &c. for], are referred to.
