Articles resembling diaper, or mosaic work, are made of gutta-percha threads of different colors or shades, very rapidly and economically. In the manufacture of paper, an article very difficult to rend, and which will, therefore, be found extremely suitable for documents exposed to much tear and wear, as bills of exchange, certificates, also for wrappers, envelopes of all sorts is formed by interposing between two sheets of paper pulp threads of gutta-percha, laid cross-wise like net work, at distances of an inch or two apart, more or less, and combining the two sheets by any suitable machinery as heated rollers. The gutta-percha thread may also be plaited either in the naked or sheet state, into hats, cans, bonnets, or into bags, baskets, basket work, or into coverings for chairs as a substitute for cane, or into whips, bridles, reins, or into any other similar articles—and finally, cordage of great strength may be made by twining together threads of gutta-percha with threads of flax, or other durable fibrous material, by the same processes as are ordinarily followed in the manufacture of the different sorts of cordage. The following described Patent for improvements in Boots, Shoes, Gaiters, &c., is of great importance, inasmuch as it fully describes the method of manufacture, the solution used, &c. It will be observed that Mr. Keene mixed caoutchouc or India-rubber with gutta-percha. This process is now found to be very detrimental to the durability of the boot, shoe or gaiter, inasmuch as a rubber mixture is sure to become decomposed by the oils in the upper stock or soles. It also renders the shoe a nasty, sticky mass, making it impossible to repair them. The process has been tried here, evidently a copy of the Keene patent. After an expenditure of thousands of dollars, the manufacture of boots and shoes by this admixture of India-rubber _has been abandoned as impracticable_. _Gutta-percha, on the contrary, is not affected by oils_, and here is the grand secret of the success and triumph of boots and shoes cemented by it. Goods of various descriptions, including boots and shoes, were largely manufactured in England, between 1845 and 1848, which, being made with a mixture of India-rubber and other foreign matter, were thus rendered valueless. In six months after many of these varieties of elegant fabrics were put into the market, they were discovered to be a sticky mass of worthless trash, or where the rubber was omitted became brittle like glass. _Whereas, goods that were manufactured from the pure gutta-percha, such as picture frames, &c., remained uninjured to the present day_, and are now apparently as firm and indestructible as when first made. Here follows the Patent. CHARLES KEENE, of Sussex Place, Regent’s Park, Esq., for improvements in Boots and Shoes, Gaiters, Overalls, and other like articles. Patent dated May 29th: Specification enrolled November 29th, 1845.
