WATERPROOFING FABRICS.

SPEGIFICATIQN forming part of Letters Patent No. 273,233, dated February 27, 1883.

I Application fi led October 31, 1882. (Specimen-s.)

To all whom it may concern:

Be it known that we, WM. H. HORNER and FRANCIS HYDE, citizens of the United States of America, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Waterproofing Fabrics; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates more especially to textile fabrics, cordage, &c., and in treating the same after it is manufactured with a composition which will render the fibers of the fabric stronger, water and acid proof, whereby the fabric is better enabled to resist the deteriorating effects of time and the action of acids upon the same.

In carrying out our invention, which is designed more especially to be applied to the manufactured article or fabric, we employ a composition which is made up essentially of rosin and paraffin e or other mineral oils, which are the principal andessential elements which remain upon the fabric. These elements of our composition make an essentially acid and water proof mixture, which, when applied .to a textile fabric or other material, will impart the aforesaid qualities to the same. In order to apply these ingredients to the fabric or other material, we make use of benzine or other volatile liquids which will reduce and com bine with the rosin and oil, so that they can be readily applied to the fabric.

The ingredients of our compositionthat is, rosin and paraffine-oil, the latter being preferably what is known to the trade as heavy distillant, and also whatis known as Foots oil, though any other paraffine-oil may be employed with advantage-these ingredients that is, the rosin and parafline-oil-are boiled together until they are assimilated or thoroughly mixed and incorporated with each other, afterwhieh the mixture is thinned down or reduced from a heavy to a comparatively light consistency or liquid form with benzine or spirits of turpentine, (one or both may be used,) or other volatile liquids may be employed.

The ingredients of this composition are used in about these proportions, to wit: to one hundred pounds of rosin, twelve gallons of paraffine-oil, which are boiled together so as to be thoroughly incorporated with each other,

These proportions may be varied, without departing from the spirit of our invention, according to the different fabrics and uses to which the fabrics are intended to be put. Benzine, turpentine, or other volatile liquids are mixed with the rosin and oil after they become cooled, to reduce their consistency and allow them to be readily applied to the fabric.

When the composition is applied the volatile substances, as benzine, disappear by evaporation, leaving the rosin and parafline-oil, which are dissolved by the benzine and thoroughly assimilated with each other, in and on 1 all fibers of the fabric.

After the mixtureis ready to be applied the fabric is dipped in. the solution, or it may be otherwise applied, so that all the threads, fibers, and parts of the fabric will become thoroughly saturated and impregnated. The fabric is then removed from the composition and it is manipulated so as to remove the surplus or a part of the composition, which manipulation may consist of wringing the fabric or passing the same through rollers or other mechanical means for pressing the same, so as to leave the fabric dampened and wet with the composition.

The fabric, after being dried, is ready for use, and while being dried the greater portion of the benzine disappears. as hereinbefore described, and which remain upon the fabric, are practically acid-proof, and tend to preserve the fabric from decay. They also render the fabric moth-proof, and do not The resin and oil, 7

ric and render the same acid and water proof.

It also renders the fabric softer and more pliable.

The common varieties of resins, or those which are made from crude turpentine by distillation, and commonly known as rosin, is also acidproof to agreat extent, and its qualities in this respect are not impaired to any ICC great extent even by caustic soda or acetic acid, though it is readily dissolved by such liquids as benzine, ammonia, and oil of turpencomposition, and when they are applied to the fabric so as to impregnate the fibers thereof they impart this quality to the fabric.

It is evident that any fabric which is treated with the com position herein described is rendered acid and water proof and is madestron ger and more durable. Though the fabric is rendered heavier, its pliability is not impaired, and it may be employed for treating all kinds of woven materials or fabrics, as burlaps, canvas, fish-nets, cords, ropes, &c.; or the fabric may be treated after it is manufactured into articles, as bags for fertilizers, tents, awnings, netting, overalls, 850.

One of the principal uses to which we put our invention is to treat bags so as to render them acid-proof and otherwise stronger, so-

that they will resist the deleterious action of acids as contained in phosphates or other commercial fertilizers.

This composition, when applied to bags, besides rendering them acid and water proof, adds very materially to the strength of the same, and it does not materially change the appearance or pliability of the same, and the bags can be handled and sewed with the same readiness as the untreated bags now in use.

This application is designed as an addition or supplement to the patent obtained by as September 5, 1882, which is numbered 263,907, in which we reserved the right to make subsequent application for the composition process or method of treating bags and similar articles or textile fabrics.

We are aware that it is not broadly new to combine with paraffine-oil pitch made from cotton-seeds as a water-proof composition, or pitch, tar, and paraffine as a waxing composition,'and that compositions for treating leather to render it water-proof, in which parafline, tallow, and resin are employed, is not new and we do not claim such as our invention, as they would not answer the purposes set forth in our W application.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The improved method of treating textile fabrics to render them acid-proof, which consists in saturating and impregnating the fabric with a composition consisting principally of rosin and paraiiine or other mineral oils, which are reduced to a proper consistency, with a volatile liquid, and in removing the surplus quantity of the composition from the fabric by pressure, for the purpose set forth.

2. A composition for treating textile fabrics,
