LOOM` FOR WEAVING FIGUREDIDOUBLE PILE FABRICS.

SBECIEICATION forming part of Letters Patent No. 354.358, dated December 14, 1886. Y

Application filed May 27, 1886.

To all whom it may concern:

Be it known that I, TOM I. SHUTTLEWORTH, a citizen of the United States, residing in Amsterdam, Montgomery county, New York, have invented certain Improvemehts in Looms for Weaving Figured Double Pile Fabrics, of which the following is a specification.

My invention relates to looms for weaving gured double pile fabrics, my invention con- 1o sisting in certain novel means for operating the pile-threads, whereby on the rise of the Jacquard lifter-board any desired pile-thread may be drawn down from the upper warp into the lower fabric or drawn up from the lower warp into the upper fabric, so as to produce two fabrics having a corresponding figure.

In the accompanying drawings, Figures 1, 2, and 3 are diagrams illustrating the method of weaving the fabric in accordance with my 2o invention, Fig. 4, adiagram showingsufcient of a loom to give a proper understanding of my invention; Figs. 5 and 6, diagrams illustrating the operation of the heddles controlling the ground-warp threads; Figs. Z and 8, 2 5 diagrams illustrating the operation of the harness controlling the pile-warp threads, and Figs. 9 and 10 are views illustrating modifications of my invention.

Each of the fabrics has a number of pile- Warps, x, and two ground or backing threads, y, the number of pile-warps depending upon the number of colors in the pattern to be produced.

The operation of weaving the fabric will be understood upon reference to Figs. 1, 2, and 8. In Fig. l the threads are represented as they appear after the figuring pile-warps have been drawn from the upper to the lower and the lower to the upper fabric and bound 4o in by the fillingshots 1, all of the upper pile- Warps being then elevated and the lower pile- Warps depressed and the ground or backing warps of each fabric crossed, so as to form upper and lower'sheds for the insertion of the binding-shots 2, which are thrown in and beaten up and the ground-warps of each fabric then again crossed, as shown in Fig. 2, to form sheds for the bindingshots 3, and after throwing in these shots the ground-warps of 5o each fabric are again crossed to form upper Serial No. 203,412. (No model.)

and lower sheds, all of the upper pile-warps except those for the figure being lowered to the level of the bottom of the upper shed, and all of the lower pile-warps except those for the gnre being raised to the level of the top of the lower shed, as shown in Fig. 3. Such of the upper pile-warps as are necessary to form the figure are drawn down into the lower shed, and such ofthe lower pile-warps as the figure demands are lifted into the upper shed, as shown in Fig. 3, preparatory to throwing in the binding-shots 1, which con-l reels from which the pile-warps :r are drawn,-

g/ the beams which supply the upper and lower ground-warps, c a the heddles for operating said ground-warps, and b b heddlesv for operating thick fillingor stuffing warps w, which are drawn from beams w. These stuffing-warps alternate with the sets of pilewarps x, thelatter and the stufiingwarp preferably passing through alternate dents in the reed.

The heddles a a have double eyes, as shown in Figs. 5 and 6, the threads 'y of t-he upper fabric passing through the upper eyes of the heddles and the threads y of the lower fabric through the lower eyes, these eyes being so related and the lift of the `heddles being such as to effect the proper formation of the upper and lower sheds.

Each of the pile-warps x is controlled by a harnessthread connected to one of the needles d of the jacquard and passing through the usual notched eye in a lifter-board, f, above said jacquard-needles, each harness.- thread having a knot above the lifter-board, so that when the thread is adjusted by the needle .so as to bring this knot over a notch of the board ksaid knot and that portion of the thread in ICO y which, inthe presentinstanceLacts upon knots upon the harness-threads of the pile-warps of the lower fabric, while the lower board acts upon knots upon the harness-threads of the pile-warps of the upper fabric, and these boards are caused to move toward and apart from each other, so that on the rise of the upper board, g, all of the pile-warps of the lower fabric, except the iigure-warps, will belifted from the position shown in Figs. 1 and 2 to that shown in Fig. 3, the descent of the lowerboard, h, causing the corresponding pile-warps of the upper fabric to drop to the same extent. The ,comber boards remain separated while the binding-shots 1 are being thrown in, after which they are drawn together, so as to restore the warps under their control to the positions shown in Figs. 1 and 2.

Such of the pile-warps as are desired to forni the figure are by means of the j acquard brought under control of the lifter-board, which has a movement in excess of that imparted to the comber-boards, so that said figuring pile-warps will be carried up or down into the opposite fabric, as set forth in the beginning of the specification.

The figuring-threads ofthe lower pile-warp are simply elevated by the action of the lifterboard as the latter rises in the usual manner but it is necessary to transform this rising movement ofthe lifter-board into a downward movement of the f1 guring-threads'of the upper pile-warp; hence in accordance with one plan of carrying out my invention I pass each of the harness-threads of said upper pile-warps around a pulley, z', or other bearing, double it back upon itself, pass it again through the eye of the lifter-board, and connect it at the lower end to a strip, m, of rubber or other elastic material, secured to the guide-board n below the Jacquard apparatus, or to any other available point of connection. The lifter-board acts upon a knot on this returned portion of the harness-thread, so that the lift of the board serves to stretch the spring and permit the drop of the weighted portion of the harnessthread which controls the warp-thread, said warp-thread being lifted on the descent of the board by reason ofthe contraction of the spring m, which exerts a force considerablyin excess of the weight. These operations will be understood on reference to Figs. 7 and 8.

The lifter-board of the jacquard is operated by a cam, 1, on a shaft, 2, the cam acting on a slide, 3, which is connected by a rod, 4, to a lever, 5, connected to the lifter-board by a rod, 6.

The comber-boards are operated by a cam, 7, on theshaft 2, this cam acting on a slide, 8,

which is connected by a rod, 9, to a lever, 10, and by a rod, 11, to an arm, 12, the lever 10 being connected by a rod, 13, to the upper comber-board, g, and the arm 12 by a rod, 14, to the lower comber-board, 7L, so that the desired movements of said boards toward and from each other are e'ected,

The Jacquard cylinder, heddles, lathe, takeup rolls, camshaft, and other parts of the loom may be operated by mechanism, which need not be described, as it forms no part of my invention. I may say, however, that the patent of Bigelow, No. 16,870, January 13, 1857, shows mechanism which is available for the purpose.

In the modification of my invention shown in Fig. 9 the harness-threads which control the pile-warps of the upper fabric are doubled at the lower end instead of at the upper end, and pass round rollers t', carried by a bar secured to the frame of the loom. In this case the knot is on the main portion of the harness thread, above the lifter-board, and the eye for the warp-thread is on the returned portion of said harnessthread, t-he upper end of which is connected to the elastic cord m, so thaton the rise of the knot under the action of the lifterboard the harness-eye will be depressed and the spring m stretched. But one comber-board is used in this ease, said board having eyes for both portions of the doubled harness-threads.

It will be evident that a weight may take the place of a spring as a means of maintaining the returned portion of the harness-thread in its normal position; but the spring is preferred. It will be evident, also, that my invention can be used in connection with Jacquard apparatus of that class in which lifterbars f are used in place of an eyed and notched lifter-board, and lifter-hooks s are used instead of knots in the harness. (See Fig. 10.)

I claim as my invention- 1. As a means of drawingaplethread from the upper to the lower fabric in weaving gured double pile fabrics, the combination of a lifter board or bar and operating mechanism therefor with a harness-thread having a doubled or turnedback portion with elastic or weighted end, that part of said thread on one side of the turn having the knot or equivalent device for the action of the lifter board or bar, while that portion of the thread on the other side of the turn has the eye for the passage of the warp-thread, all substantially as specified.

2. The combination, in a loom for weaving figured double pile fabrics, of the Jacquard lifterboard, its operating devices, and the straight harness-threads controlling the pilewarps of the lower fabric,with harness-threads controlling the pile-warps of the upper fabric, and each having a doubled or turned-back portion with elastic or weighted end, all substantially as specified.
