UNITED STATES PATENT OFFICE.
AUGUSTUS SCHULTZ, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF, AND EDWARD A. 'A. SCHULTZ, OF PHILADELPHIA, PENNSYLVANIA.
PROCESS OF SIZING FlBROUS MATERIALS.
SPECIFICATION forming part of Letters Patent N0. 308,807, dated December 2, 1884.
Application filed May 8, 1884.
To all whom it may concern.-
Be it known that I, AUGUSTUS SCHULTZ, a citizen of the United States, residing at New York, in the county and State of New York,
have invented new and useful Improvements felt, threads, or yarnsfirst to the action of glue or other gelatinous material in the pres ence of a chromate of an alkalisuch as bichromate of potash or sodaand then to the action of sulphurous acid.
In carrying out my invention I first prepare a solution of a chromate of an alkali-such as bichromate of potashand asecond solution of glue or gelatinous matter. These two solutions I mix together in the proportion of about sixteen per cent. of glue and two per cent. of bichromate of potash, the mixture when complete showing a clear yellowish color. Into this mixture I place the dry fibrous material, and keep it therein until itis thoroughly saturated, which is accomplished in about twenty minutes if the liquor is kept hot, not boiling.
Instead of placing the fibrous material into the liquor, as above stated, the liquor may be applied with a brush. I arrive at the same result if the fibrous material is first impreg nated with glue or gelatinous matter, then left to dry, and afterward exposed to the action of the chromate of an alkali, which is best ac complished by introducing said material into a solution of bichromate of potash in the presence of an acid, such as hydrochloric acid. After the fibrous material has been well pene- (No specimens.)
trated by the chromate solution it is taken out 0 and freed from the surplus adheringliquor by pressing or otherwise, and then it is exposed to the action of sulphurous acid. For this purpose I prepare a solution of sulphurousacid gas in water or a solution of a sulphite or other salt, which, when brought in contact with an acid, will evolve sulphurous acid.
The fibrous material prepared in the manner above described, either dried or not dried, is entered intothis bath and kept therein until it is thoroughly penetrated, which may be accomplished in from fifteen minutes to several hours, according to the strength of the solutions employed. After the penetration is complete the material is removed from the bath, freed from the surplus liquid, and finally dried or otherwise manipulated. Bythis process a deposit is formed in the body of the material which imparts to the same great strength and durability.
What I claim as new, and desire to secure by Letters Patent, is
The within described process for sizing fibrous materials-such as textile fabrics, felt, threads, or yarns-said process consisting in first exposing the materials to the action of glue in the presence of an alkaline chromatosuch as bichromate of potash or soda-and then to the action of sulphurous-acid gas or a solution thereof, substantially asset forth.
In testimony whereof Ihave hereunto set my hand and seal in the presence of two subscribing Witnesses.
AUGUSTUS SCHULTZ. [L. s.]
