DOUBLE-PILE FABRIC SPECIFICATION forming part of Letters Patent N 0. 683,708, dated October 1, 1901.

Application filed February 24, 1900. Serial No. 6,346. (No model.)

To all whom it may concern.-

Be it known that I, I-IoVoEP SARAFIAN, a citizen of the United States, and a resident of Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and Improved Double-Pile Fabric, of which the following is a full, clear, and exact description.

The invention relates to textile fabrics commonly known as oriental rugs; and its object is to provide a new and improved oriental rug in which the pile stands up straight, having no tendency to lie down, as in an ordinary oriental rug, and which can be readily and quickly woven without the aid of skilled labor and without any Waste of material and at the same time combine a fine appearance with great durability and firmness in weave.

The invention consists of novel features and parts and combinationslof the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of my invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a sectional perspective view of the improvement. Fig. 2 is a diagrammatic view of the mode of weaving the rug. Fig. 3 is a sectional perspective view of the finished weave, and Fig. 4 is a like view of the weave of an ordinary oriental rug.

In weaving my improved oriental rug two fabrics A A are formed and arranged opposite each other with sets or pairs of warpthreads at b in the fabric A and similar sets or pairs of warp-

threads

1 and 2 in the fabric A. The pile weft-thread B is interwoven with a pair of warp-threads in one fabric and then crossed over to the other or second fabric, to be there interwoven with a pair of warp-threads, and then the pile weft-thread B is recrossed or returned to the first fabric to be interwoven with the next adjacent pair of warp-threads and then again passed to the second fabric for a like operation. This is repeated for all the pairs of warp-threads in the two fabrics. B y reference to Fig. 1 it will be seen that the pile weft-thread after interweaving a pairof warp-threads in one fabric passes directly over to an opposite pair of warp-threads in the other fabric and interweaves with the warp-threads in this pair, after which the pile weft-thread returns ina diagonal direction to the first fabric to interweave with a third pair of warp-threads adjacent to the first pair of warp-th reads already interwoven by the pile weft-thread. In interweaving the pile weft-thread B with a pair of warp-threads a b or 1 2 the said weft-thread is looped around the Warp-threads of the pair, as at B, the crossing pile ends B? extending from between the pair of warp-threads and the connecting portion B of the pile weft- .thread extending from one warp-thread to the other between the crossing pile ends ]3 on the inside of the fabrics A A. In Weaving the fabrics a binding and separating weftthread 0 is interwoven with the warp-threads of each fabric A A and alternately with the pile weft-threads, so as to connect the warpthreads with each other throughout the width of the fabric and form a solid back or ground for each fabric.

In order to keep the fabrics A A the desired distance apart d uring the process of weaving,

use is made of a transverse plate D, set edge-' wise between succeeding picks of pile weftthreads, the plate being formed at one projectin g end with a horizontally-disposed knife E, having a curved cutting edge, so that after the fabrics are woven and the plate D is withdrawn and the knife E passes through the weave then the cutting edge of said knife cuts'the crossing pile weft-threads abouthalfway between the fabrics A A to separate the latter and to form two rugs of the same pattern at the same time, the pile ends standing straight out or at a right angle from the body of the fabric. (See Fig. 3.)

In weaving the fabric on a loom the position of the warp-threads a b 1 2 during the first pick is indicated on top of Fig. 2 with the shuttle traveling in the direction of the arrow from left to right and with the warpthreads at b 2 above and the warp-thread 1 below the shuttle. After the first pick the position of the warp-threads is changed by a Jacquard or other machine, so that for the second pick the warp-threads a b are above and the warp-threads 1 2 are below the returning shuttle. On the third pick the warpthreads at 1 are above and the warp-threads ICO b 2 are below, and during the following fourth pick the warp-threads a b are above and the warp-threads 1 2 are below the shuttle, the same as in the second pick above described. In the fifth pick (see bottom of Fig. 2) the warp-thread b is above the shuttle and the warp-threads a, 1, and 2 below the shuttle, and. then during the following picks the above -described arrangement is repeated. Instead of a single shuttle a number of the same may be used, the same as on ordinary box-looms, to form a pile of different colors by the use of diiferently-colored pile weftthreads to produce a predetermined design in the fabric.

Ordinary oriental rugs, the structure of which is shown by Fig. 4, generally are woven as a single fabric, as the pile weft-thread F loops the pair of warp-threads G G, as at F, the pile ends extending at one side of the connecting portion F as is plainly shown in Fig. 4. In such rugs the pile ends F tend to lie over flat away from the connecting portion F as the latter only supports the pile ends on one side, while in my arrangement it is not only possibleto weave two fabrics at the same time, but in addition the pile ends stand straight up from the back or ground and have no tendency to lean either way as the connecting portion 13 passes between the pile ends on opposite sides, as will be readily understood by comparison of Figs. 3 and 4.

The double fabric described can be readily woven on a loom specially constructed for the purpose without the aid of skilled laborand without waste of material, and at the same time the finished rug has a very fine appearance, is exceedingly durable on account of the regular weaving, and the fabrics can be quickly woven in contradistinction to the slow process of weaving ordinary orieu tal rugs.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A weave for the manufacture of oriental rugs, consisting of two opposite fabrics each composed of pairs of warpthreads, and a crossing pile weft-thread arranged to cross from a pair of warp-threads of the first fabric to an opposite pair of warp-threads in the second fabric,the pile weft-threadinterweaving the individual warp-threads of each pair with each other and the pile weft-thread re crossing from the second fabric to the first fabric to interweave the warp-threads of a pair of warp-threads adjacent to the first pair of warp-threads from which the pile weftthread started, substantially as described.

2. A weave for the manufacture of oriental rugs, consisting of two opposite fabrics each composed of pairs of warpthreads, a pile weft-thread crossed from one fabric to the other for connecting the pairs of warp-threads with each other and for interweaving the individual warp-threads of each pair, and a binding and separating weft-thread for binding the warp-threads in each fabric and ar ranged alternately with the. said pile weft thread, the said pile weft-thread in crossing connecting the first warp-thread in the one pair with the second warp-thread in the opposite pair, and the pile weft-thread in recross ing connecting the first Warp-th read in the opposite pair with the second warp-thread in the adjacent pair of warp-threads, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HOVCEP SARAFIAN.
