WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 793,524, dated June 27, 1905.

Application filed June 11, 1904. Serial No. 212,203.

To (all 11/71/0111, it may concern.-

Be it known that I, HARRY D. I-IEWETT, a citizen of the United States, residing at 39 Charles street,Providence, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Woven Fabrics, of which the following is a specification.

This invention is an improved woven fabric with woven tucks, and it is characterized particularly by a woven backing which prevents the tucks from drawing or pulling out. The tucks produced are as strong or stronger than those made from flat cloth, and the fabric is particularly suitable for dressmaking.

The fabric is in the main one-ply; but the warp-threads are divided into three sets. In the body of the fabric these three sets all take the same weft; but at the tucks one set is looped and takes the weft of the tuck and the second and third sets are divided to each take separate weft-threads, forming under the tucks a two-ply fabric or backing, which prevents the tucks from drawing or pulling out, and after passing the tuck all the sets of warp-threads are merged into one-ply.

In the accompanying drawings, Figure l is a plan view of the fabric. Fig. 2 is a sectional diagram greatly enlarged. Fig. 3 is a diagram in plan, the tuck being indicated as cut off on the line 3 3 of Fig. 2.

Referring specifically to the drawings, three sets of warp-threads are indicated, respectively, at a, I), and c, and the weft-threads are indicated by the numerals 1 to 21 for the purpose ofillustration. The tuck is indicated at D, and theweft-threads of the tuck are indicated at (Z. The body A of the fabric is indicated in the diagrammatic view taking the weft-threads 1 to A and 16 to 21, said body being formed in the ordinary manner. The warp-threads a form a backing under the tuck. The warpthreads 0 are looped to form the tuck, and the warp-threads b are woven with the threads 0 to form a rib or binding layer O at the foot of the tuck. In producing the tuck and the rib referred to the proper loom mechanism is employed, and the warp-threads are first separated into two sheds, one being formed by the warp-threads a, producing the backing, and the other by threads 6 and c, producing the rib referred to. The two latter sets of threads are further separated, and the threads 0 are looped to produce the tuck, the weft (Z being woven therein. The warp-threads a and the Weft woven therein produce a continuous woven fabric throughout the length of the piece of goods and, in connection with the warp-threads 7), serve to sustain whatever pressure or weight may be applied to the goods without danger of drawing, the woven por' tion producing the rib referred to and formed by the warp-threads Z) and c, and the weftthreads (indicated at 5, 7, 9, 11, 13, and 15) also assist in preventing the drawing of the tuckthreads by providing a woven portion between the foot of the tuck and the body of the fabric, affording two layers or a two-ply fabric, which effectively prevents any drawing of the threads forming the tuck and also adds greatly to the ornamental features of the cloth. By appropriate loom mechanism the tucks and the spaces therebetween can be made any width desired and can be woven in What I claim as new, and desire to secure by Letters Patent, is-

1. A tucked woven fabric having part of its Warp-threads looped to form the tuck, and having two continuous woven plies extending under the tuck and one ply between the tucks. 2. A tucked woven fabric having three sets of warp-threads woven into one ply between tucks, one set of which threads are looped to and a tuck formed by looping one of the said form the tuck, and the other sets of which are facing sets.
