TOKUJ'I NAEMURA, or Salter-romances, JAPAN.

Specification of Letters Patent. Patented May 24:, 1921.

Application filed ill/lay 15, 1920. Serial No. 381,678.

To all whom it may concern:

Be it known that I, TOKUJI NAEMURA, subject of Japan, residing at No. 138 Isobe- Dori, Sanchome, Kobe, Japan, have invented new and useful Improvements in Matting, of which the following is a specification.

This invention relates to matting woven with filaments of grass bundled into comparatively flat and wide cords, with thinner filaments on both sides of each cord as the warp and weft, thereby filling up interstices which would otherwise be left between warps and woofs by their interlacmg. An object of this invention is to obtain a strong and durable matting having comparatlvely smooth surface and no big interstices between warps and wefts. Another object 1s to improve the appearance by weaving thereinto any desired number of warps or wefts,

or both, of different widths, thereby forming striped pattern.

The accompanying drawing shows matting woven according to my invention 1n which:

Figure 1 is a general plan v1ew.

Fig. 2 is anenlarged plan v1ew showlng the texture.

Fig. 3 is a section taken on the line 33 of Fig. 2.

Fig. 4 shows one form of cords to be used as the warp and weft.

Fig. 5 shows another form of the warp and weft.

Fig. 6 shows a form of filaments to be used for filling up interstices between warps and wefts.

Fig. 7 is an enlarged plan view showing longitudinal stripes, and

Fig.8 is a section of Fig. 7 on the line 8-8.

Fig. 9 is an enlarged plan view showing transverse stripes, and

Fig. 10 is a section on the line 10-'-1O of Fi 9.

The same reference number refers to the same or corresponding part throughout all the figures.

In Fig. 1, 1 is the ground of the matting while 2 and 3 are respectively longitudinal and transverse stripes. In the figure, stripes are shown as formed near the edges by way of a border pattern, but I need not say that such stripes may be formed at any desired part.

The ground of my matting is woven, as is shown in Figs. 2 and 3 with the warp and weft 4 of straw, rush or any other grass 5 generally used for such purpose, braided as shown in Fig. 4, or twisted as shown in Fig. 5, into flat and broad cords. Such cords however become very stiff by braiding or twlsting, and when woven into a fabric, there will be between warps and wefts big interstices left by their interlacing. Thus, the fabric is not only unsightly, but becomes easily worn, as its surface is uneven. Now, this drawback can be avoided by placing smaller and more flexible filaments 7 on both sides of each warp and weft. These filaments 7 for filling up interstices are also straw, rushes or any other grass collected into any desired thickness but not braided nor twisted, so that they retain their flexibility. Or if desired they may be wound with thread 6 as shown in Fig. 6. Thus, according to my invention three warps and three wefts are used, one braided or twisted cord 4 at the middle with two flexible ones 7, one on each side; and the fabric woven in this way is comparatively more even in its surface and compact in its texture, and consequently pleasing to sight and durable in use.

To weave stripes into matting at any desired place, replace any desired number of warps 7, 4, 7 with thinner warps 8, preferably colored, of the same kind of material with which the ground is woven, or of cotton or hemp threads collected into any desired thickness, or of cords of cotton or hemp fabric, passing this time only one warp through one heddle-eye. Then weave any desired number of warps of similar kinds as are used for forming longitudinal stripes at any desired places, passing only one weft at each shed. In this way, longitudinal and transverse stripes can be formed.

I claim:

1. A matting woven with warps and wefts each of which-consisting of a comparatively wide cord with cords for filling up interstices one on each side, each set of the three cords of the warp and weft being woven as one, and in which transverse stripes are formed by replacing some of the wefts consisting of three cords with a number of single wefts, substantially as and for the purposes hereinbefore set forth.

2. A matting woven with warps and wefts each of which consisting of a comparatively Wide cord with cords for filling up interstices one on each side, the set of the three cords of the warp and Weft being woven as one, and in which longitudinal and trans verse stripes are formed by replacing some of thewarps' and wefts of three cords each with a number of single warps and single wefts, substantially as and for the purposes hereinbefore set forth In testimony whereof I have signed my name to this specification.
