MANUFACTURE OF FLOOR-COVERING.

Specification of Letters Patent.

Patented Jan. 27, 1920.

Application filed December 11, 1915. Serial No. 66,345.

To all whom it may concern:

Be it known that I, J o F UNAHASHI, citizen of Japan, residing at No. 66, 2 Cl1ome, Wakillama, Kobe, Japan, have invented certain new and useful Improvements in the Mannfacture of Floor-Covering; and I 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 to woven floor coverings manufactured of vegetable fibers or fibrous material and particularly to a floor covering in which the weft is composed of relatively thick strands or threads of rush, straw, grass, hemp or the like, while the warp consists of relatively fine threads of cotton or other suitable material.

Instead, however, of interlacing the alternate threads of the warp above and below the weft threads throughout the fabric, as is usual in plain weaving, the warp threads are floated over two or more weft threads in any desired portion of the fabric surface, so that these floated threads serve to work out any desired figures or patterns on the surface. In order to hold down and prevent displacement of the floated warp threads of the pattern, there is also employed a separate weft or filler thread, which may be termed the binder filling, this binder filling being suitably interlaced with the warp in such manner as to securely hold the floated threads in position. In the most desirable form of my invention, each thread of the binder filling overlies one of the relatively thick weft strands instead of lying between said strands.

The general object of the invention thus briefly described above is to work out any required figures or patterns on the floor c0v ering by means of the warp threads which are made to come out on the upper surface of the fabric as described; and furthermore to increase the durability of the fabric by preventing displacement of the floated threads composing the patterns or figures.

Two practical embodiments of the invention are illustrated more or less diagrammatically by way of example in the accompanying drawings, in which:

Figure 1 shows a preferred fabric construction in plan, where the number of the warp threads appearing on the wearin surface and back of the fabric are unequaI;

Fig. 2 is a longitudinal section on the line .A-A of Fig. 1;

Fig. 3 shows in plan another fabric within the invention, the number of warp threads appearing on both sides of the fabric being equal in this case;

Fig. 4 is a longitudinal section on the line BB of Fig. 3.

Referring to the drawings, the relatively coarse weft or of rush, straw, grass, able vegetable fiber, which fibers may be employed individually or twisted together into a strand of the proper size. The warp threads are indicated at 2 and are small as compared to the filler strands. 3 represents the so-called binder filling, consisting of small threads of cotton, hemp, or papyrus yarn. It will be noted that in the fabric lllustrated in Fig. 1, the binder filling threads 3 are arranged to overlie the coarse filler strands 1 at those locations where said threads are performing their function of binding down the floated warp threads.

The desired figures produced by thus weaving the warp may be worked out in many different ways. For instance, when warp threads of more than two different colors are used, the same figure may be produced in different colors on the face and back of the floor covering, one color for the face and the other color for the back. If in such case the number of warp threads appearing on the face of the fabric and on the back be unequal, the binder thread, controlled by the tension strength of the warp, acts to hold down the raised or floated warp threads on the face where they appear in greater number (Fig. 1). On the other hand, if the warp threads appear on both sides in equal number their balanced tension strength causes the binder thread to press down the floated ortion of the warp at the middle of the weft (Fig. 3).

Among other advantages secured by the lnvention is the ability to work out figures resembling those produced by printing. This is made possible by floating the warp threads as described, by using warp and weft threads of different sizes, and by the use of variously colored warp threads; but the figures produced are very much more fast and durable than printed figures. Moreover, the cost of production is less. The use of the binder filling threads prevents the possibility of the floated warp 1 represents filler strands hemp or other suitthreads being caught and broken When the floor covering is in use, especiallyas in the preferred form of the invention, each of the binder filling threads, which are equalin number to the Weft threads, ties down all or" the floated warp threads.

What I claim is 2 1. A fabric for floor covering or the like Which comprises suitable Warp threads and Weft threads, certain of the Warp threads being -floated over several Weft threads to produce pattern eifects,in combination with binder filling threads equal in number to the Weft threads and tying down the floating portions of the Warp threads, each binder filling thread overlying a Weft thread.

2. A fabric for floor covering or the like whlch comprlses relatlvely small Warp threads, Weft threads of relatively larger size, at least a part of the Warp threads having portions floated over several Weft threads to produce pattern efiects, in combination'with binder filling threads, each of Which ties down all the floated Warp threads and overlies a weftthread.

In testimony whereof I hereunto afiiX-my signature in the presence of two Witnesses.
