CHENILLE WEFT AND METHOD OF MANUFACTURING THE SAME.

SPECIFICATION forming part of Letters Patent No. 289,203, dated November 27, 1883.

Application filed September 25, 1882. (No model.) Patented in England November 2-2, 1880, No. 4,842.

- To in whom itmaly concern:

ing the. same.

The first step in the manufacture of woven chenille weft is the weaving of a fabric which is subsequently cut in strips, lengthwise of its warp, the strips of chenille thus produced being employed as weft in the manufacture of Arminster carpets orrugs.

To determine the distance that each shoot of chenille weft shall be drawn through the shed in order to bring the various colors in the proper positions required to form the desired figure, it has hitherto been the custom to put a mark or shoot of hemp or cotton, of different color or material from that of the main body of the chenille weft or fur, at certain points in the length of the woven chenille, so that the chenille weft may be drawn through the shed of the warp until the guide-marks register with the selvages of the fabric being woven, thus adjusting the various colors in their proper positions.

My invention particularly consists in weaving the preparatory fabric with open spaces or skips in the weft at certain determined points of its length, which spaces are bound on either side by interweaving with the warp a number of weft shoots of finer material than the worsted shoots, which constitute the pile of the carpet or rug. These open spaces are formed by interweaving with the warp strips of wire or other hard material, which are subsequently withdrawn.

In order that the method by which I propose to carry my invention into effect may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure l is a section taken longitudinally of the warp of the preparatory fabric, which is subsequently cut in strips to form the chenille weft. Fig. 2 is a face view of the san1e,'showing a chenille weft-strand detached.

In the process of weaving the preparatory fabric, after interweaving a certain number of coarse worsted or pile-weft threads with two or more sets of warp-threads, I interweave a number of fine shoots, a. I then weave in a strip of wire or other hard material, I), then another section of fine shoots a, and then resume the interweaving of the coarse worsted shoots a, which are to constitute the pile of the carpet or rug. These operations are repeated until the desired length is reached. The wire gages b are then drawn out, and the fabric thus formed is cut lengthwise of the warp in strips of a width necessary to form the desired thickness of chenille weft. In weaving carpets or rugs, the chenille thus formed is employed as weft,as is usual, and the spaces left by the withdrawal of the wires b are placed so as to register with the selvage edges of the fabric being woven, the weaving of the carpet or rug being carried on in the usual way. It is then only necessary for the attendant to watch the drawing in of the weft-thread and prevent its guide-spaces being drawn past the selvages of the fabric being woven.

It will be seen that owing to the expansive nature of theheavy worstedwefts c, if it were not for the presence of the small threads a, (which are preferably of tightly-twisted material,) the saidheavy worsted shoots would expand, thereby becoming badly displaced, in addition to closing up the guide-openings.

It is obvious that the strips 12, which are to form the guide-openings, and the fine bindingthreads or may be of any suitable material and weaving two or more sets of warp-threads for ting the fabric thus formed longitudinally be- 15 a certain distance with pile 0r fur weft -th reads; tween the warp threads into strips, 1 substannext interweaving such warp-threads with a tially as and for the purpose herein set forth.
