_Claim._—Incorporating with gutta-percha, substantially, the proportion of sulphur, or its equivalent, herein specified; and then subjecting it to such a degree of heat, and for such a length of time, as to expel therefrom its injurious volatilizable ingredients, preparatory to vulcanizing the gutta-percha thus treated, or of using it in the condition that said process of treatment puts it into. _Ninety-second_, to Daniel Haywood, August 29, 1854. For improvement in the manufacture of India-rubber. The improvement consists in the use of the steam-jacket both for the mould and the die employed in the manufacture of India-rubber goods, and in the sudden introduction of cold water after the hot steam into the jackets. By the first device the vulcanizing of new articles is alleged to be more perfect, and the remelting and remoulding of old, worn-out India-rubber to be rendered attainable. By the second device the degree of hardness of the product, or its adhesiveness on the surface, can be moderated at pleasure. The drawings exemplify the improvement as applied to manufacturing buckets. _Claim._—The claim is confined to remoulding worn-out India-rubber goods, by the means stated. _Ninety-third_, to Henry G. Tyer and John Helm. For improvement in the manufacture of boots and shoes. Patented March 27, 1855. The object of this improvement is to produce a boot or shoe combining the qualities of India-rubber with the lightness and elegance attainable by the use of other materials, and capable of being re-soled when necessary. The upper _a_ and in-sole _B_ having been cemented together, perforations are made around and through the upper _a_, until the cemented surface of the in-sole _B_ has been pierced. Then these holes are filled up with cement, and the outer sole _c_ properly cemented, is pressed upon the in-sole. If sufficient strength be used, slightly to separate those several parts of the sole, see fig. 2, the rubber filament can be seen in threads H. as represented in fig. 2. The inventors say,—we disclaim the use or application of this our device, or invention to any other matter or thing than is described, and set forth. We claim the uniting of the outer sole and upper, manufactured wholly or in part of vulcanized India-rubber, with the in-sole of boots and shoes, by means of cement, the cement passing through preparations made for that purpose in the upper, in the manner substantially and for the purpose described. _Ninety-fourth_, to John M. Wimley, (Assignor to J. &. B. Shaw), June 12, 1855. An improvement in attaching gutta-percha soles to Boots and Shoes. The melted gutta-percha is filled into mould A, up to the rim B, and the shoe placed thereon and firmly pressed down, until the sides of the shoe come in contact all around with the rim B. The gutta-percha is forced into, and through the holes purposely made, through the in-sole and edges of the upper.
