198 GOODYEAR ON GUM-ELASTIC. 



EMBOSSED FABRICS. 



The fabrics which are embossed with the greatest advantage, 

 are gum-elastic veneers, plated goods, and vellum. 



This leaf is a specimen of the thinner sort of embossed vellum, 

 such as is designed for pocket books, paper boxes, &c. The 

 heavier kinds are made in imitation of morocco and leather, for 

 book-binding, trunks, and other uses to which leather is applied. 



The art of embossing with cambrics, and other fabrics, was 

 first adopted by the inventor in 1835, before the discovery of 

 either the acid gas or the vulcanizing process. The method of 

 embossing, which is described page , is of importance on 

 account of its simplicity and cheapness, for although gum-elastic 

 goods may be embossed with callenders, like leather or other 

 fabrics, the figures cannot be made to endure the heat of the 

 vulcanizing process so well in that way ; and the cost of the 

 patterns, if embossed with callenders, is enormously increased 

 by an expensively engraved callender, which is I'equired for 

 each pattern. 



By the method of embossing with other stuffs, the figure is 

 first transferred in the manner described, into a piece of India 

 rubber fabric ; which, after it is vulcanized, answers all the pur- 

 poses of a costly engraved metal callender, for embossing other 

 India rubber fabrics. The original not being injured by the 

 copying of it into gum-elastic, gives to this process the ad- 

 vantage of an unlimited variety of styles and patterns, at a very 

 trifling expense.
