To all whom t may con/cem:

Be it known that I, LITTLETON KIRK- rATmCK, a citizen of the United States, and a resident of Wilmington, in the county of New Castle and State of Delaware, have inventedl a certain new and useful Coated Fabric, of'which the following is a specification.

The object of my invention has been to provide a coated fabric which shall be adapted for use, among other purposes, for automobile tops, or the linings of such tops, for slip covers, trunk linings, etc., and, while made of comparatively cheap material, shall have the appearance of expensive material and which fabric shall also, if desired, be waterproof, oilproof and dustproof.

This application is a division of my application Ser. No. 245,991 filed July 22, 1918.

ln the accompanying drawing,

Figure 1 is a representation of an embodiment of the'product aspect of my invention having the appearance of wh1pcord;

Figure 2 is a sectional view of Figure 1.

While my invention is capable of embodiment in many different forms and by the practice of different processes, lI have chosen as an illustration of my invention the application of-it to the production of a fabric having the appearance of whipcord, such as is used, for instance, in the lining of automobile tops, but this illustration'of my invention is to be regarded only as typical and my invention is not to be confined thereto.

Whipcord has a characteristic appearance, giving rise to its name, and which appearance I desire to imitate.

As a base for my imitation whipcord, I use any woven fabric possessing suflicient tensile strength and elasticity, as for example, a cotton drill, this cotton drill being eithcr undyed or dyed any convenient color, l preferably first coat the goods with a White pyroxylin jelly, 'which may be composed-of any of the coating compositions ordinaril used in the coating of fabrics for the pro uction of leather substitutes, of. which the following formula may be cited as an example:

Parts. Zinc white 4 Nitrocellulose 4 Castor oil 8 Amyl acetate 12 Wood alcohol 12 Benzol 10 This jelly is applied preferably to the back side of the goods with a sharp knife while the goods are under tension.

The object of applying the coating is not only to waterproof the goods and thereby prevent mildew and shrinkage to which untreated cotton fabrics are susceptible, but. alsoto give a body or stiness to the goods, so as to facilitate the subsequent treatmentA of the goods. l

The putting of the, goods under tension results in applying a very light 'coating of the jelly to the goods and it opens the threads in the direction ofthe pull, so that the coat is forcedin to a greater extent than would otherwise be the case.v

By applying a very light coating in this Vmanner there results but little, if any,

change in the textural configuration of the Y surface, the elevations and depressions characterizing the weave of the particular fabric used remaining to form the surface of the coated material.

Having applied the coating to the goods v as described and given it time to harden, color is applied to the fabric with a sharp knife and with the goods under tension. The color coating may be of any composition ordinarily employed in the coating of fabrics for the production of leather substitutes, of which the following formulaI may be cited es an exemple, assuming that the desired color is bleek:

The lrnife forces the color down into the small cavities or depressions in the surface and scrapes it 0E of the tops of the threads which form the elevations, so es to expose the White beneath, thus giving life to the fabric. That is, the eieet is produced of the lights on top of threads and the shadows between the threads of e woven fabric, instead of the dead monotony that would be obtained from a. coating all of one color. This effect is in part dependent on, and varies with, the Weave of' the goods, and een be obtained by the use of any contrasting colors, the first coat being preferably lighter than the second.

The other side of the goods may be heevily Weter-prooeflor given any desired treatment to better enable that side to stand the Westber.v The initiel coat to stii'ien and Water-proof the goods may, if desired, be applied to the opposite side of the goods .from that which is 'to reeeive the seeond or Clerk Colored coat, but in this event, the Woven eppeerenoe will be less perceptible then ir the two costs are applied to the sein-e side. K

There are many kinds of goods suitable Yfor use in making my fabric by my process; i'or instance, esteem, drilis and molesirins iney be used. The color e'ieet een, or course, be Varied Without limit.

l claim l A. ooe/ted fabric comprising e Woven base, s coating entirely covering seid base, and e contrasting coating occupying 'the eerities, but no; covering the elevations, ineident to the particular Weave of said bese,

ln testimony whereof l' six my signature.
