VICTOR O. OLSEN, OF
CHICAGO, ILLINOIS, ASSIGNOR TO CHARLES MGADAM COMPANY,
OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
COMPOSITION FOR USE IN FINISHING DRY-CLEANED LEATHER.
No Drawing. Application filed July 1,
To all whom it 91mg concern Be it known that I, VICTOR O. OLSEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Composition for Use in Finishing Dry-Cleaned Leather, of which the following is a specification, reference being had to the accompanying drawings, and to the reference characters marked thereon, which form a part of this specification.
The invention relates to a process and product for finishing leather. The invention is particularly adapted for use in finishing leather articles which have been cleaned by the ordinary dry cleaning process.
In the ordinary dry cleaning process as now practiced. leather articles, such for example as white gloves, are usually first cleaned by treatment with a solution of gasoline soluble soap (dry cleaners soap) in gasoline. naphtha or some similar solvent. The cleaned articles are then given a rinsing treatment in gasoline or naphtha to remove the soap after which the process is completed by allowing them to dry. The procedure, while it improves the appearance of soiled or dirty white leather articles very markedly, does in fact leave the article somewhat stiff and of decidedly uneven color. r
A primary object of my invention is to overcome these two objections named and to enable the dry cleaners to turn out white liable condi tion and with uniform color. Iy invention being especially adapted to use in connection with white goods, I shall describe that adaptation of the process and product thereto; but I desire it to be understood that my process will prove equally useful in connection with leather of other colors if a pigment is selected of substantially the same color as the leather article to be finished.
The most convenient (practical) method of utilizing my invention is to prepare the finish in the form of a paste containing all of its essential ingredients and then dissolve the proper quantity of this paste in the gasoline or naphtha intended for rinsing the articles, but the various individual ingredients of my finishing material may be added to 1920. Serial N0. 393,469.
the rinse separately and the same result thereby attained.
In preparing my mixture, I prefer to take 30 pounds of petrolatum and render it fluid by heat in a vessel equipped with a steam jacket and suitable mixing device. To the liquefied petrolatum, I then add 15 pounds of cottonseed oil and 50 pounds of zinc oxide, mix the whole very thoroughly and allow the mass to cool, continuing the stir-- ring until it has thickened sufficiently to prevent separation of the pigment. The result is a homogeneous pasty mass. This I utilize for the finishing of cleaned leather articles by adding 2 ounces of it to 10 gallons of the naphtha or gasoline which is to be used for rinsing the cleaned goods. The goods are then rinsed in this mixture using the ordinary device of the trade for the purpose.
The result of the use of my finish is that its oily constituents impregnate the leather and after evaporation of the naphtha they remain in the leather and give to it the highly desirable characteristics of softness and pliability. The pigment constituent is deposited in extremely thin film on the surface of the goods and covers the traces of stains which are impossible to remove by the cleaning process, thus giving a uniform white finish to the articles so treated.
It will be found that goods which have been dry and subsequently treated-by my finishing process are vastly superior in the qualities listed above,softness, pliability, and uniformity of color, to goods which have been treated by the ordinary process of dry cleaning. It will be obvious that other oily or unctuous substances may be substituted for the petrolatum and cottonseed oil mixture described above and that other pigments may be used to take the place of zinc oxide. Therefore, I do not intend to limit myself to the exact materials-or proportions hereinabove stated.
I claim as my invention:
1. A composition for use with a solvent in the finishing of dry cleaned leather goods comprising petrolatum, cottonseed oil and zinc oxide.
2. A paste for use with a solvent, in the finishing of dry cleaned leather goods, comprising petrolatum, cottonseed oil and zinc presence of two witnesses, this 25th day of oxide in substantially the following propor June, 1920. tions: petrolatum thirty pounds, cotton- Y seed oil, fifteen poimrls, and zinc oxide, fifty VICPOR Q 5 pound.
Witnesses:
CHARLES MoAnAM, J. P. REILLY.
In testimony that I claim the foregoing as my invention I ullix my signature, in the
