CHENILLE.

SPECIFICATION forming part of Letters Patent No. 621,641, dated March 21, 1899.

` Application filed Apri18,1898. Seria1No.e7e,911, (specimens.)

color or shade and a cut fur of another color These objects I attain in the man-k or shade. ner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure l represents a piece of my improved chenille, showing the same partly untwisted.

Fig. 2 represents a piece of the web from.

which said chenille is made. Fig. 3 is a diagram illustrating the method of weaving said web, and Figs. 4, 5, and 6 are similar diagrams illustrating modifications of my invention.

The improved chenille fabric shown in Fig.

l consists of a central heavy incased or inclosed core l, from which project uncut chenille loops 2 and a cut chenille fur 8, which in the twisted chenille form spiral convolutions,with the uncut loops and the out fur lying side by side, the core l being exposed between the convolutions when the chenille is not tightly twisted. In producing chenille of this character I preferably employ two bunches of heavy core-strands 4, separated from each other in the loom to the desired extent and each flanked by sets of fine warps 5, the loom being also provided with selvage wires or warps 6, as shown in Fig. 3.

When it is desired that the uncut loops of the chenille shall be of a color or shade different from the cut fur or pile, I use three sets of wefts 7, 9, and l0. The wefts 7 are shot back and forth between and around the bunches of core-threads 4, so as to be wrapped first around o ne of these bunches and then around the other and are interwoven with the inner sets of ine warps 5. The wefts 9 and lO are each shot between and around one of the bunches of core-strands and one of the selvage wires or warps 6, so as to pass alternately around the same, and these wefts are interwoven with and bound by the outer sets of fine warps 5, as will be fully understood on reference to. Fig. 3, the result being the production of a web such as shown in Fig. 2, which is then divided on the central longitudinal line, so as to produce two webs, each with'a central core inclosed or incased by the weft-yarns and having on one side projecting uncut loops 2 and on the other side a projecting cut fur or pile 3, which when the chenille is twisted will produce the effect shown in Fig. l. t

It desired, more than two sets of chenillewefts may project from the central inclosed or incased core of the chenille by simply increasing the number of wefts employed in the weaving, and by vemploying a multiplicity of selvage-warps the projecting chenille yarns may form a pattern instead of presenting plain straight edges, as shown.

Where it is not desired that the uncut loops shall be of a different color or shade from the cut fur or pile, only two sets of wefts l1 and 12 may be employed, as shown in Fig. 4, each weft being shot from a selvage warp or wire across the adjoining bunch of core-strands 4 v and around the farther bunch, so that each weft will be bound on each side of the bunch of core-strands which it crosses and on the inner side of the bunch of core-strands around which it passes. Y

A still simpler method of weaving the chenille is that representedl in Fig. 5, in which but a single weft 13 is employed, this weft being shot across from one selvage warp or wire to the other, so as to pass around the same alternately and crossing both bunches of core-strands in its passage, but being tied down on each side of each bunch of corestrands by the fine wefts 5.

In Fig. 6 I have shown still another method of weaving myimproved chenille, this method dispensing with the warps 5, the chenille-weft being interwoven with'the core-strands 4, so as to be retained thereby, andy said corestrands being incased or inclosed by a separate weft 15, Which is Wrapped around the same in the manner shown.

-v Having thus described my invention, I claim and desire to secure by Letters Patent" l. A Woven chenille having a core and strands Which pass under and over said core and by contact With each other throughoutr the length of the chenille completely inclose or incase said core, projecting portions of inclosing strands forming a chenille-pile, substantially as specified.

2. A Woven chenille having a core, and strands which pass under and over said core and by Contact With each other throughout the length of .the chenille completely inclose or incase said core, projecting portions of instrands which inclose or incase said core and v project from the same on each side to form the chenille-pile, the strands on one side of the core forming loops and those on the other side having cut ends, substantially as specified.

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

ERNST ENGSTFELD.
