"fates-ted June 19, 1966;

To all whom it may concern;

Be it known that I, THoMAs BENTON DOR- NAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Irn rovements in Woven Pile Fabrics, of which t e following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

My-invention relates to woven pile fabrics, and has for its obj'ectstightweaving and effective tying of the pile-loops, economy in the material employed, and simplicity of construction, and particularly aconstruction capable of being rapidly and effectively woven.

In pile fabrics, such as are knownas three shot, as heretofore made the weft-threads have beeninclosed in loopsof binder war threadsin groups of three weft-threads eac and ordinarily a single loop ortuft of pile warp-threads has been provided for each of 1 these groups of three weft-threads. Another construction of three-shot pile fabric is that disclosed in my Patent No. 773,130, dated October 25, 1904, in which the pile is compile-loo osed of threads bound by weft-threads in i j oth the upper and lower plies of the fabric thread of each of employed.

My present invention aims to attain the a in each group of three weft threads orbound by each weft-thread throughout the fabric.

advantage over ordinary three-shot of a greater numberof pile-loops in proportion to the weft-threads and to'attain this advantage by a construction of fabric in which none of the pileloops' are bound by weftthreads in the lower ply.

My invention includesthe revision of a for each weft-thread of the upper ply of t e fabric with twice as many weftthreads in theupper ply as in the lower ply, thereby attaining avery compact and tightlywoven condition in the upper ply, while securing the advantage of a weft-thread in the lower ply in each group of three weft-threads to assist intightly gripping the pile-loops. As compared with ordinary three-shot pile fabrics my-ncw fabric has twice as many pile loops in pro ortion to the weft-threads, and as com are with ordinary two-shot and Other i e fabrics my new fabric effects a saving o' one-fourth of the weft-threads employed. a l

My invention also includes a new arrangement of binder warp-threads whereby greater compactness and rigidity and body of the fabrlcare attained.

I w1ll .now particularly describe the construction of fabrics illustrated in the accompanying drawings and will thereafter point out my lnventionin claims.

Figure 1 is a dia rammatic view illustrating a vertical longitudinal section of a portion of a pile fabric embodying my invention with uncut pile-loops, Fig. 2 is a similar view illustrating the same portion of the fabric with the pile cut and sheared. Figs. 3, 4, 5, and 6 aresimilar .views illustrating modi fied constructions with uncut pileeloops.

In the constructions shown in Figs. 1 to 5, inclusive, the weft-threads are arranged in sets of six weft-threads each, the several weftthreads in each set being designated by the numerals 1, 2, 3, 4, 5,'and 6, respectively. Each of these drawings illustrates two successive sets of weft-threads.

In the construction shown in Fig. 6 the Iweft-threads are arranged in sets of three weft-threads each, the several weft-threads in each set bein numbered 1, 2, and3, re

, spectively', and our successive sets of weftreads being shown. Each of the drawings shows one warpthe sets of warp-threads In the construction shown in Figs. 1 and 2 and hereinafter s ecifically claimed three I: binder warp-threaj s a, b,- and c, and five fig uring warp-threads T, U, V, X, and Yare shown.

Two of the binder warp-threads! and b passfrom fly to ply after every third shot in opposite irections, so as to bind the weft-threads in loops of three weft-thrads each, as u'sual in three-shot pile fabrics.- The third binder warp-thread 0 passes over one of the upper-ply weft-threads in each group of three weft-threads and under the lowerply weft-thread of each group of three weft threads, passing from theupper ply to the I lower ply between the first and second and between the fourth and fifth weft-threads of each set and returning from the lower tply to the up er ply between the second and ourth weft t reads of each set and between the fifth weft-thread of one set and the first weftthreadof the next set, thus additionally bind ing the weft-threads together and producing thereby a more compact and rigid fabric and tending to prevent shrinkage during the weaving .of the fabric. This additional 1 0 binder warp-thread also and more effectively construction shown in Figs. 1 and 2 no stuffer warp-threads are provided, the drag-warp or pile-forming warp-threads not at the time employed as pile-forming threads lying between and separating the two plies.

The figuring warp-threads T, U, V, X, and Y are shown as arranged in five sets and may be of different colors. They are separately brought to the upper surface to form the pile, and the threads unused at any place are buried in the fabric as usual in Brussels and Wilton fabrics. The pile-loops may be formed over longitudinal pile-wires, and a pile-loop is formed for each upper-ply weftthread 1, 3, 4, and 6. Thus there are two pile-loops in each group of three weft-threads and no pile-loops which have to be pulled down to the-lower ply. As shown, the pileforming figuring warp-thread T forms the pile atthe set of six weft-threads shown to the,left, and the pile-forming figuring warpthread U forms the pile at the set of six weftthreads shown to the right. The greater number of weft-threads in the upper ply causes the upper ply to be more tightly beaten up by the lay than the lower ply, and thus the upper-ply weft-threads are forced tightly together and tightly bind the pile, while the lower-ply weft-threads also materially assist in tying the pile tufts or loops tightly up against the upper-ply threads.

In the construction of fabric shown in Fig. 3 the arrangement of binder warp-threads and stuffer warp-threads of ordinary threeshot pile fabrics is employed, two sets of binder warp-threads a and I) and one set of stuffer warp-threads 8 being employed. In other respects the construction of this fabric is the same as of the fabric shown in Figs. 1 and 2.

In the construction of fabric shown in Fig. 4 three binder warp-threads a, b, and c are employed, the binder warp-threads a and 6 being arranged in the same manner as in the constructions heretofore particularly described and the binder warp-thread c passing over one of the upper-ply weftthreads of a group of three weft-threads (shown as the weft-thread 1) and under the lower ply of the next group of weft-threads (shown as the weft-thread 5) so as to additionally bind the fabric, but not so tightly as in the construction shown in Figs. 1 and 2. The stuffer warp-threads are here omitted.

In the construction shown in Fig. 5 three sets of binder warp-threads are employed, the binder warp-threads a and b separately binding the lower-ply weft-threads of each alternate group of three weft-threads and the binder warp-thread 0 remaining always in the upper ply and passing under one weft-thread and 3, respectively, in each set.

of that ply and over the next weft-thread of that ply, and so on throughout the fabric. By this arrangement each weft-thread is bound in a separate loop of binder warpthreads. Here also the stuffer warp-threads are omitted.

In the construction shown in. Fig. 6 the weft-threads are arranged in sets of three weft threads each and are numbered 1, 2, Two sets of binder warp-tlneads are also shown, and a set of stuffer warp-tineads is employed. The binder warp-tlnead a passes over the upperply weft-thread 1 and then through the fabric and under the lower-ply weft-thread 2, and it then passes upward obliquely through the fabric and over the weft-thread 1 of the next set, and so on. The binder warp-thread 1) passes downward obliquely through the fabric and under the weft-tlnead 2 and then upward through the fabric and over the weft-tlnead 3 and then downward obliquely through the fabric and under the weft-thread 2 of the next set, and so on. The stu'll'cr warp-thread 8 passes between the plies, as usual.

In the weaving of my new fabric the ordinary operation of lifting the selected pileforming threads to form the pile when the lay is in backward position, the shed is open, and the shuttle is being thrown to insert the lower-ply weft-tlnead is employed in forming the pile-loops between the first and third weft-threads of each group of three weftthreads; but as there is no following lowerply weft-shot between the last weft-shot of each group of three weft-tlneads and the first weft-shot of each following group of three weft-threads this ordinary operation cannot be employed, and, in place thereof I employ the loom operation described in my Patent No. 780,488, dated June 9, 1.903, for a pile-fabric loom wherein the selected figuring Warp-threads to form the pile are raised for that purpose while the lay 1s in forward position, so that the pile-loop is formed and the figuring warp-tlnead which formed the loop is depressed to the lower part of the shed before the shuttle is thrown to insert the first weft thread in each group of three weftthreads. In other respects the loom operations for weaving my new fabric are such as are ordinarily required for the weaving of the particular fabric which it is intended to produce.

In weaving the fabric shown in Figs. 1 and 2 the first o )eration would be the elevation. of the selecte figuring-warps to form the pile, and then the shed would be formed with the binders a and 0 up and the hind er Z) down and all of the figuring-warps down. The first shot would then be made by the shuttle. For the second shot the binder a would be up and the binders b and 0 down and all of the figuring-warps would be at the upper part of and a down, and all of the figuring-warps. would be down. Then Whenthe lay was in forward position the selected figuringwarpthreads to form the pile would be elevated,
