One hundred and fifth, to Charles Morey, citizen of the United States, residing at Paris, France, Jan. 9, 1855. For improvement in re-working hard rubber compounds.
The material is placed in an iron mould closed and subjected to a powerful pressure. It is then placed between two red-hot iron plates, and thus again introduced into the press. When the mould is sufficiently hot, it is put into cold water until it has become cool. The soldering, after the article is taken from the mould, is performed in the following manner: The broken parts are scraped off; dust of hard vulcanized India-rubber is introduced between the scraped parts; the whole is submitted to a high degree of heat and pressure, whereby the broken parts are united in a perfect manner.
Claim 1st.—Forming or moulding scrapings, filings, dust, powder, or sheets of hard vulcanized India-rubber, into a compact, solid mass, by means of a high degree of heat and pressure, as above described.
Second.—The application of dust powder, filings of hard vulcanized India-rubber for soldering or uniting hard vulcanized India-rubber.
One hundred and sixth, to Henry G. Tyer and John Helm, Jan. 30, 1855. For improvement in processes for making India-rubber cloth.
The India-rubber compound, (in a plastic state) is introduced at C, between cylinders 1 and 2, as it passes between the said cylinders, and adhering to cylinder 2, is carried round and down until it comes nearly in contact with cylinder 3, when the end of roll of cloth A is inserted between cylinders 2 and 3, and the compound is pressed upon and into the cloth by the action of the cylinders. When the cloth and compound thus united on one side have passed round cylinder 3 until they have have become nearly in contact with cylinder 4, the end of the cloth from roller B is inserted between cylinders 3 and 4 so as to come in contact with the compound on cloth A. The two pieces of cloth, with the compound between them, then pass between cylinders 3 and 4, when the two pieces of cloth become firmly united with the compound.
Claim.—The process described of making elastic fabrics without a previous preparation of threads, strips, or sheets, or the coating of the cloth by cement.
One hundred and seventh, to Sylvanus H. Whorf, assignor to himself and Charles Rice, Jan. 8, 1856. For improvement in the manufacture of boots and shoes.
The inventor says: “I do not claim uniting the sole to the upper by means of cement, made to extend through the upper alone, but what I do claim as my improvement, is the manufacture of a shoe by cementing its sole and upper in extending the cement not only through perforations in the upper, but in and through the perforations made in and through the in-sole or the outer sole, or both, the same presenting great advantages, not only in securing the parts together, but in rendering them water-proof when the cement employed is of a character to resist water.”
One hundred and eighth, to G. Tyer and John Helm, New Brunswick, N. J., Jan. 9, 1856. For improvement in making gum-elastic cloth.
