woven FABRIC.

Specification of Letters Patent.

Application filed June 9, 1917. Serial No. 173,783.

To all whom it may concern.-

Be it known that I, WILLIAM M. STEVEN- soN, a citizen of the United States, residing in Springfield, Massachusetts, have invented certain Improvements in Woven Fabrics, of which the following is a specification.

My invention consists of certain improve ments in the manufacture of woven fabrics, especially carpets and rugs, and hereinafter. for convenience, referred to as a rug, and has as its purpose, the production of a multicolor rug in such a way that although only two sets of warp threads are used in the weaving of the rug the finished article will show more than two, say five, different colors on its face and will present the appearance of having been woven with five sets of warp threads. A rug produced in accordance with my invention, while equal in appearance to a' much higher priced rug, may be sold for a relatively small sum owing to the greatly reduced cost of manufacturing and the less amount of material required.

My invention is especially adapted for use in connection with the so-called fiber rugs in the weavin of which two sets of warp threads are employed, one set c0nsisting of wool or cotton fiber and the other set consisting of twisted paper strands. Such a rug usually shows, on its face, a figure or design, formed by the fiber warps, and displayed against a background of paper warps. The conventional practice is to have the fiber warps of a darker color than the paper warps so that the rug presents a dark figure on a' light background. My invention consists in applying color or colors to a portion of or all of the background formed by the paper warps with the result that the rug will, instead of being two-toned, present a design possessed of any desired number of different colors.

In the accompanying drawing, which shows one end of a rug adapted to be finished in accordance with my invention, I have illustrated a conventional design and border by means of cross lines on a plain background. For sake of example, say that the cross lines represent a design formed of brown fiber warps and the plain background represents light tan paper warps. In finishing this rug according to my process, I will apply color or colors to any desired portion of the background. For instance, I desire to add to the brown and tan effect, three others colors, say, red, blue and green. These three colors I will apply, as shown on the drawing, to such portions of the background as are marked, respectively, B, B and G. The finished rug will then display five colors and, unless very closely examined, will present the appearance of having been woven with five differently colored sets of warp threads.

The application of color to the background is readily effected as the paper warps used in this type of rug are very nearly as absorptive as blotting paper. If oil colors are used, they will be permanent, and the rug may be subjected to hard usage and even washed. without deleterious efiect upon the colors.

The colors may be applied by hand, with an ordinary paint brush, but the method I prefer is to make use of a shield of heavy cardboard or light sheet metal, this shield having in it a perforation or series of perforations corresponding in size and contour with that portion of the background that it is desired to color. This shield is laid over the rug, exposing that portion of the background while covering the remaining surface and the color is then applied by means of an air brush. This method insures an even distribution of color and will produce better results should it be used by an unskilled workman.

It will be noted that the pattern of the rug is wholly the result of the weaving operation, the design or pattern of the finished rug. except as to the coloring, being precisely the same as in the rug as it left the loom, the subsequently applied color being only to such parts of the rug as have already been shaped by weaving, that is to say, each of the unshaded portions of the design shown in the drawing is formed by threads which come from the back of the fabric to the face and in all other portions are buried under the shaded threads, the latter in turn being buried under the unshaded threads where the latter appear upon the surface.

A rug made in accordance with my invention will therefore look exactly like a rug woven with as many sets of threads as there are colors in the pattern, and in this respect will be wholly distinct from one in which the design or pattern is produced by printing it upon the face of a fabric woven uniformly throughout, for in the latter there Patented Dec. 16, 1919.

is no change of threads from one face of the fabric to the other where the pattern changes. My invention is equally applicable to the weaving of rugs in which the pattern or design is formed by the weft threads instead of by the warp threads.

I claim:

1. The process herein described of pro ducing amulti-colored fabric, said process consisting in first so weaving a fabric with light and dark threads as to form a pattern or design and then applying color to parts of the design formed by the light threads so as to produce the effect of a fabric woven with more than two differently colored sets of threads.

2. The within described fabric having light and dark threads interwoven to produce a pattern or design parts of the light threads constituting elements of said pattern or design being dyed or colored to differentiate them from other parts thereof.

In testimony whereof, I have signed my name to this specification.

WVILLIAM M. STEVENSON.
