_Eighthly_, “My invention consists in forming in manner certain varnishes which may be applied to the water-proofing of leather or cloth, and in applying them either alone or mixed, without coloring matter, to gutta-percha or its compounds, or to articles made from them, they may have _a fine, glossy exterior given to them_, and the smell of any ingredient which may have been mixed up with them, and which may be of an offensive nature, (such as sulphur) may be effectually shut in. For this purpose I take the gutta-percha, or gutta-percha combined with “jintawan” and caoutchouc, or either of them, orpimented or sulphureted as before described, or sulphurize and dissolve it by confining the mass in a steam-tight vessel, and by placing that vessel in a chamber heated by steam or other convenient means to a temperature of 300° to 380° Fah., or I mix gutta-percha and caoutchouc, or gutta-percha and “jintawan” (using the substance indifferently, so far as the proportion one bears to the other,) with sulphur or orpiment, or other sulphuret, in the proportion before directed to be observed, where these substances are introduced with about eight to ten parts of animal or vegetable wax, or of animal or vegetable fatty matter, and then dissolved in rectified spirits of turpentine, and evaporate as before. As these varnishes combine readily with colors, they afford the means of rendering a numerous class of articles, such as elastic rings, bands, bandages, straps, &c., much more extensively, suitable and vendible than before. These varnishes mixed with colors, may also be used for the purpose of painting or printing cloth, leather, or any other fabric. These varnishes will also be found very useful as cements, particularly in combining gutta-percha and its compound, with silk, cotton, and other textile fabrics.” * * * * * _Eleventhly_, “My invention consists in making cards for carding cotton and other fibrous materials, in manner following—I make the backs either of _gutta-percha alone_, spread in a plastic state to a sufficient thickness on a cloth, or felt, or other suitable foundation, or of any of the gutta-percha compounds which are of sufficient flexibility and consistence for the purpose. And I insert the metal teeth in these backs, according to any of the known methods followed in the manufacture of such cards.” _Twelfthly_, “My invention consists in mixing with the gutta-percha prepared in the manner first hereinbefore described and exemplified in the masticating machine, shellac, or resin, or asphalt, or some other resinous or bituminous matter; and when the materials are thoroughly amalgamated, I spread the mixture while in a fluid state, upon cloth or leather, or any other suitable foundation. * * * * *
