UNITED STATES PATE T OFFICE.
E. P. HUDSON, OF NEW YORK, N. Y., ASSIGNOR TO NEW YORK WATER- PROOF PAPER COMPANY, OF NEW YORK CITY.
IMPROVEMENT IN THE MANUFACTURE OF RUBBER-COATED PARCHMENT-PAPER.
Specification forming part of Letters Patent No. 107,687, dated September 27, 1870.
Be it known-that I, E. P. HUnsoN, of the city, county. and Stateof New York, have invented an Improved Vulcanized Material from Paper Body; and I do hereby declare that the followingis a full and exact description thereof.
I take .the material produced by my improved process, for which I have made application forLetters Patent, and which I will here briefly describe.
The paperlunsized) is first dipped in or passed through a bath composed of two volumes of commercial sulphuric acid and one volume of water, kept at a temperature of 60 Fahrenheit. Then, after washing it in clear water, it is passed through a bath of very dilute aqua ammonia. Again, after washing in water, it is passed through. a bath of very dilute lime-water, and after washing once more in water, and while still wet, it is passed through a bath of glycerine, thus completing the process, and producing a material possessed of the very valuable qualities of stren gth, pliability, and imperviousness to water; but for uses where the material is much or long exposed to water, or to atmospheric changes, it is desirable to DJEI-kOylIllGlIltttGllEbl more durable and unaffected by those influences.
To produce such a material, I take the material produced by the above-described process and treat it substantially as follows: A very liquid solution of india-rubber in benzine or other solvent having been prepared, the material is immersed therein, and, after recent. of the caoutchouc used; or a portion of the sulphur may be mixed with the previous glycerine bath, and, of course, a less quantity is then required in the benzine solution or to be dusted on the material afterward.
This vulcanizing process may be applied either to single thicknesses of the paper material or to united thicknesses. I
What I claim as my invention, and desire to secure by Letters Patent, is-- 1. Treating paper previously subjected to the acid and glycerine processes with indiarubber and sulphur, and then to the action of heat, substantially as herein specified.
2. As a new article of manufacture, the material thus produced.
