Title: Improvements in or relating to shoe part stiffeners
IPC: A43B23/08
Filed: 1933-05-22
Abstract: Relates to the manufacture of shoe stiffener blanks of the kind in which an absorbent fibrous base such as swansdown is charged    with a solution of a cellulose compound such as celluloid and consists in (1) reducing the viscosity of the solution by the action of an amine, e.g. an aliphatic amine or an aliphatic acid derivative of an amine, or an aliphatic acid potassium sodium or ammonium salt; and (2) employing methylic alcohol as a solvent, which permits the blank being brought to a firm and fleshy translucent condition for handling and skiving by subjecting it to the action of water to gelatinize the solution.  On dipping or otherwise treating with from 5--30 per cent of the weight of the celluloid content of ketones, such as acetone, alcohols, such as diacetone alcohol, esters, such as butyl acetate, and with the aid of pressure to remove the liquid released, the gel or coagulum may be again rendered plastic for lasting or canning. The rate of action of the solvent dip on the celluloid may be controlled by adding benzol or like diluent.  Alternatively, from 2--12 per cent of celluloid may be incorporated in the dip.  A plasticiser such as tricresyl phosphate, triphenyl phosphate, di-butyl phthalate or the like, to the extent of 5--10 per cent of the celluloid content may be added to the dip to give flexibility to the shoe stiffener in the shoe.  A resin or resin ester or pigment such as powdered slate or plaster of Paris may be added to the dip to give hardness and to assist adhesion of the blank in the finished shoe.  A small percentage of one or more of the primary, secondary, or tertiary amines of the aliphatic compounds may be added to increase the celluloid content of the solution without increasing the viscosity.  Specifications 340,603, 355,349, and 416,863, [all in Group VII], are referred to.
