SOLUTION FOR WATERPROOFING FABRICS.

1,240,3d5. No Drawing.

To all whom it may comerm Be it known that I, TrroMA's 0. James, a citizen of the United States, and a reeldent of Chicago, in the county of Cook and have invented certaln new and useful Improvements-in Solutions for Waterproofing Fabrics; and I do hereby declare that the following is a' full, clear, and exact description thereof.

This invention relates to. an improved solution for water-proofingfabricsand consists of the matters hereinafter despribed and more articularly pointed out in the appended c aim.

The object of my invention in to produce a mixture or preparation for the purpose of water proofing fabrics, superior to the preparations now in use, which may be prepared with ease and at considerable less cost than the cost of preparations now used for snmlar purposes.

In carrying out my formula I make a mixture of on -half pound of acetate of lead and one-half pound of powdered alum, with three gallons of water, and place the same in tatedor stirred until the acetate of lead and the alum is thoroughly dissolved therein, after which the solution is left at rest for a suitable length of time, to permit of the deposit of sediment on the'bottom of the vessel. The solution or mixture in the vessel is then withdrawn by means of a siphon or any suitable device which will not disturb the sediment in said vessel, and is then measured and placed in a second vessel provided therefor.

For each gallon of the drawn ofi mixture and in proportionate amounts for each proportionate part of a. gallon, I add one ounce of gum arabic which has been dissolved in benzin or a similar hydrocarbon or in an alcoholic body such as wood alcphol. The gum arabic may be dissolved m any other volatile chemical which is not in itself oleaginous or greasy.

The water-proofi g mlution is now ready 1 Specification of Letters Patent.

for use and the manner of applying it to the fabric for the purpose of making 'the latter impervious to Assuming the fabric to be in the bolt, said bolt is immersed in the solution and when thoroughly saturated or impregnated, the bolt of fabric is removed from the solution and passed through a suitable compressing or wringing device to expel all the surplus solution therefrom. Thereafter the fabric may be dried by artificial means or by exposure to the atmosphere.

The solution may be applied equally as well to a ready made garment as to fabric in the bolt. In the case of a coat, uniform or the like, for example, the garment is laid out fiat upon a table or other suitable surface, and then saturated with the solution by a sponge or'rag which has been 7 or by other suitable means, by movingthe wet sponge or rag over the garment in the manner in water is as follows:

Fabrics after having been water-proofed with my improved solution, retain their original color and shape and the presence of the water-proofing solution is not noticeable in the fabric even upon close inspection of the same. Any fabric, whether woven or knitted, regardless of its texture, may be so treated to make the same water proof.

' Garments, after being treated with my 1mbe worn without any proved solution may discomfort to the wearer, so thoroughly does the solution impregnate the texture, and make the samethoroughly water-proof. Exposure to the rain for hours will not change the fabric, so eficiently will the water-proofing shed the rain'and "moisture. It is also to'be noted that m improved solution is not only highly e cient in use but possesses other very desirable elements of utility, namely cheapnessand simplicity m its preparation and in its application to fabrics.

Garments which have been treated with my improved water-proofing solution beside possessing the advantages above mentioned, are r ndered practically in mmable i and may also be pressed in the manner of acetate and.

alum of g um arabic dissolved in an alcoholic body.
