Claim.—An elastic fabric composed of pieces of cloth either woven with the threads of the weft in a diagonal position to the threads of the warp or of common cloth stretched so as to force the threads into such relative diagonal position, combined and caused to adhere together, exclusively by vulcanized compound of India-rubber or gutta-percha, the two pieces of cloth being first united by the vulcanizable compound and the compound being vulcanized after the union.
One hundred and ninth, to Sylvanus H. Whorf and Charles Rice, March 4, 1856. For improvement in the application of soles to boots and shoes, by means of pressure, and gutta-percha or other cement.
The nature of this invention will be understood by reference to the claim. The machine for pressing the sole to the upper is illustrated in the engraving, where H represents a hollow last, into which steam can be introduced by means of pipe I; and the sole can be pressed to the upper by means of the pressing apparatus and the platten C.
Claim.—We are aware that a gutta-percha sole has been applied to a shoe by melting gutta-percha in a mould and subsequently pressing the shoe therein. We, therefore, do not claim such. We are also aware that in book-binders’ presses, and in smoothing irons, the platten of the one, and the body of the other, have been provided with an air-chamber for the reception of either steam or heated air, or other means of heating. We, therefore, do not claim such. As we use heat not for either drying or smoothing alone, but for a different purpose, and in a process of manufacture wherein it has not been before applied, to our knowledge, in the way in which we employ it, being used by us for softening or melting gutta-percha, after it has been applied to a last, as specified; and therefore we claim our improvement in the process of manufacturing and finishing shoes with either gutta-percha soles, or soles formed of leather or other material, and united to the upper and in-sole by means of gutta-percha or its equivalent, and through the agency of pressing mechanism, as specified, our improvement consisting in supplying heat within a last by means of a chamber and pipe and steam or means of heating said last, the same not only enabling the gutta-percha of the sole to be softened or rendered adhesive while it is being pressed upon the in-sole and upper, but also serving to smooth and finish the upper, as described.
One hundred and tenth, to Richard McMullin, March 17, 1856. For improvement in processes for making elastic rubber cloth.
Claim.—Rendering vulcanized India-rubber, for the manufacture of shirred goods, adhesive by boiling it in a solution of potash, to remove the sulphur from its surface, thus fitting the sheet of rubber to receive a coat of cement, whereby it is caused to adhere firmly to the cloth, or other fabric between which it is placed, in the manner and for the purposes substantially as herein set forth.
One hundred and eleventh, to John H. Cheever, March 11, 1856. For improvement in the manufacture of India-rubber belting or banding.
One hundred and twelfth, to Charles F. Crockett, June 17, 1856. For improvement in making sheets of leather from curriers’ shavings or buffings.
The inventor says: “I do not wish to confine myself to any particular kind of cement, although I found India-rubber cement to answer the best purpose. Curriers’ glass is a good instrument to press the edges together.”
Claim.—Making sheets of leather of any desired size and thickness of curriers’ shavings or buffings, by lapping and cementing them together while in a moist state, and then subjecting the mass to pressure.
