Application July 29',

1 Claim.

The present invention relates to a woven fabric, and. more particularly, to a woven fabric intended for use as coverings for upholstered furniture.

One object of the invention is to provide a woven fabric of novel appearance having a ribbed face or right side and a smooth back or wrong side.

Another object of the invention is to provide a woven fabric having a ribbed surface of variegated appearance.

Another object of the invention is generally to produce at low cost a strong woven fabric provided with a ribbed surface of pleasing appearance.

The above objects of the invention and other objects ancillary thereto will best be understood from the following description considered with reference to the accompanying drawing.

In the drawing: 1

Fig. l is a face view on an enlarged scale of a swatch of fabric of the present invention;

Fig. 2 is a more orless' diagrammatic face view of thefpresent fabric, showing threads displaced from their normal position, for thesake of clearness in illustration of the weave of the fabric;

Fig. 3 is a sectional view on the line 3-3 of' Fig. 1;

Fig. 4 is a fragmentary enlarged view of a ribforming thread, with parts of the yarn strands shown untwisted,'for illustration purposes.

Briefly described, the fabric of the present invention, in one preferred embodiment, comprises a foundation, consisting of fine warp threads disposed in close side-by-side relation and of relatively widely spaced fine weft threads, and ribforming coarse weft threads of variegated appearance projecting from a surface of said foundation and held thereon by a relatively small number of widely spaced fine warp threads of said foundation. The coarse weft threads are disposed in pairs arranged in closeside-by-side relation, each pair forming a single rib. The ribs thus formed are disposed in relatively closely spaced relation, the space between adjacent ribs being substantially equal to the width of one rib. Each coarse weft thread is constituted by a pair of twisted strands of differently colored pre-dyed yarn twisted together with a similar pair of twisted strands whereby each of said weft threads has a variegated appearance and when woven with the foundation threads to form the ribbed fabric, imparts to the latter a variegated appearance. The fabric may be made of any suitable material, such as, cotton, natural 1935, Serial No. 33,638

or artificial silk, wool, or combinations of such materials. I

Referring to the drawing in detail, and first to Fig. 1 the present fabric comprises'a foundation I8, consisting of fine warp threads I2 disposed in close side-by-side relation and of fine weft threads I4, and has a ribbed surface pro vided by ribs I6. Each of said ribs is constituted by two coarse weft threads I8, I 8 disposed in close side-by-side relation, the ribs I6 being spaced from each other by an amount substantially equal to the width of a rib or of two of the rib forming weft threads I8.

The rib-forming weft threads I8 are secured to the foundation ID in such manner as to project maximally beyond the surface of said foundation. For this purpose, said threads are secured to the foundation III by a relatively small number of widely spaced warp threads I2, the arrangement being such that the particular warp threads which engage one of a pair of rib-forming threads I8 do not engage the other thread of said rib, but float under the latter and under severalother pairs of rib-forming threads before engaging another of a pair of such threads. Thus, for example, referring to Fig. 2, it will be observed that a warp thread I2 engages one of the weft threads I8 at the point a, then floats under the companion thread I8 and under four pairs of ribbed threads, after which it engages at b a rib thread I8. The rib-forming thread I8, which is the companion of the thread engaged at a, is secured at c by a foundation warp thread I2, which is relatively widely spaced from the warp thread I2 which engages the other thread I8 of said pair and, like the latter, the warp thread I2 which engages the thread I8 at c then floats under four pairs of threads I8 and under the thread I8 which is engaged at b, and then engages at d the companion'thread I8 of the thread engaged at b. In like manner the other pairs of rib-forming threads are engaged by different warp threads at relatively widely spaced points whereby the weft threads I8, while securely held to the foundation, project maximally beyond the surface of the latter. It will be noticed that thefine weft threads I4 of the foundation layer are arranged in pairs so that there is a weft thread I4 disposed close to each weft'thread I8 of a rib I6. As best shown in Fig. 3, the weft threads I4 are interwoven with each of the warp threads I2 and thus constitute binder threads and cause the warp threads I2, which engage the several weft-threads I8, to engage the latter throughout substantial portions of their peripheral surfaces.

An important feature of the present invention resides in providing the ribbed surface of the present fabric with a variegated appearance, which is produced simultaneously vwth the weaving of the fabric and without subsequent dyeing or printing processes. This is accomplished by utilizing a special weft thread which is constructed to have in itself, a variegated appearance, so as to obtain the desired effect when a plurality of such weft threads are Woven into the fabric' in producing the ribbed surface thereof. AQCOXd'. ingly, in accordance with the present invention,

each coarse weft or rib-forming thread It comprises a pair of threads I82: formed by twisting together a pair of differently colored strands 18y, and I82, respectively, the threads l8a: being twisted together to form the thread It]. The

strands I811 and I82 may differ in color or may differ with respect to the shades of the same color, and for the purpose of convenience in description, the term differently colored as used herein, refers either to different colors or to different shades of the same color. Thus, for example, a fabric of particularly pleasing appearance was produced in accordance with the present invention by weaving the foundation; including the fine warp and fine weft threads, of green threads of the same shade and in utilizing in conjunction therewith'rib-forming weft threads I 8 in which one of the yarn strands I831 was of the same color as that of the foundation threads, and the other yarn strand I82 was of a lighter shade of the same color. The fabric thus produced was found to have a pleasing variegated appearance, and by thus introducing into the rib-forming-threads a yarn strand of a lighter shade it was found that the ribs appear to project further from the surface of the: foundation thereby accentuating the ribbed surface. It was also found, by arranging the weft threads I8 in pairs that in addition to increasing the width of each rib the variegated appearance thereof was-enhanced by reason of the. displacement in companion weft threads of the differently colored portions thereof. so'that a portion of lighter color of one rib-forming thread did not coincide, except occasionally by chance, with a similar portion of the companion rib-forming thread. Other fabrics madein accordance with the present invention were provided-with surface designs introduced during the weaving of the fabric by'jacquard apparatus, porclearly illustrating the weave of the fabric.

tions of the ribs being dropped into the foundation for that purpose.

In Fig. 1 of the drawing, the fabric has been represented on an enlarged scale in the approximate ratio of 3 to 1, and in Fig. 4 of the drawing, the weft thread l8 has been represented on the enlarged scale approximately in the ratio of 6 to 1. Fig. 2 is drawn to about the samescale as Fig. 1, except that the threads have been displaced from each other for the purpose of more It will be understood, therefore, that in the actual fabric 'the threads are finer than as illustrated and that the ribs it are more closely spaced than as shown by 'Fig. 1. Also, in the finished fabric the warp threads which engage the rib-forming threads are substantially invisible and the foundatiornas a whole, is virtually concealed, although readily seen upon close inspection.

Thus, it is seen that the fabric herein disclosed, is well adapted to accomplish the several objects of the invention, but it will be understood that while I have disclosed the preferred embodiment of the invention, certain changes whichmay. oc-

cur to those skilled in the art in view of the w present disclosure, may be made therein. There fore, I do not wish to be limited to the precise fabric construction herein shown and described, except as may be required by the appended claim considered with reference to the prior art.

What is claimed as new and useful is:

A woven ribbed fabric. comprising a ground of fine warp threads disposed in close side by side relation, ribs formed by pairs of relatively coarse weft threads which are held on one surface of said ground by a few widely spaced warp threads and projecting substantially maximally from said surface, the threads of each pair being disposed in contiguous relation, said pairs of weft threads being disposed in spaced relation on-said ground whereby the latter is exposed to view between successive pairs of said weft threads, a fine weft thread lying close to a coarse weft thread of each pair, each-of said coarse weft threads comprising a pair of twisted strands-of differently colored pre-dyed yarn twisted together with a similar pair of twisted strands whereby the ribs have a variegated appearance, said exposed portions of the ground between successive ribs being composed substantially exclusively of said closely ar ranged fine warp threads.
