GEORGE (J. MOORE, OF EAST HAMPTON, MASSACHUSETTS.

ELASTIC WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 441,107, dated November 18, 1890.

Application filed November 14, 1889' Serial No. 330,271. (No model.)

To all whom it may concern.-

Be it known that l, GEORGE O. MOORE, a citizen of the United States, residing at East Hampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Elastic lVoven Fabrics, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide an ornamental narrow elastic webbing, theornamentation being effected by an independent shirred or ruffled ply or fabric joined in weaving to the main ply or fabric, which contains the elastic warps, the union of the two plies or fabrics being effected at one or more points transversely of the webbing by warps of the elastic ply or fabric, which at the point or points referred to are raised so as to be interwoven with the shirring or ruftling consists of warps a and b and a weft c, the

"said warps being generally alternated with the said weft at each pick to produce plain weaving. The elastic ply consists, preferably, of non-elastic warps (Z and e, non-elastic filling warp-threadsf, rubber warps g, and a weft h, the non-elastic warps d and cbeing usually raised and lowered alternately at each pick, and the weft passing alternately above and below the rubber warps and filling-warps, said rubber warps and filling-warps remaining stationary in the center of the ply. The

ruffling-ply is woven fuller than the elastic ply, preferably by having a greater nu mber of picks to the inch, and is joined to the said elastic ply at one or more transverse pointsi by non-elastic warps d and e, (alternating with each other either singly or in pairs, and usually at each pick of the elastic ply and at each second pick of the ruffiing-ply,) which pass from below the weft of the elastic ply and above the weft of the ruffling ply, thus firmly joining the two plies or fabrics throughout the length of the webbing at the transverse point or points mentioned.

The ruffling-ply of the webbing is usually entirely of non-elastic threads,but may have rubber warps g in loosely-woven edges outside of the joining points i, as shown in Fig. 3, and in such case the shirring will all be between the said joining points. The rufflingply may be either narrower or wider than the main or elastic ply, an instance in which the elastic ply is narrower than the ruffling-ply being shown by Fig. 5, in which the outer edges of the said elastic ply are indicated by the dotted lines just outside of the joining points t'.

As the ruffling ply or fabric is woven fuller than the main or elastic ply or fabric, and as the latter is woven with the rubber'warps stretched or under tension, in the usual manner, it will be apparent that when the tension on the said warps is relaxed the ruffling-ply will be ruffled or shirred by the contraction of the said rubber warps.

It will thus be seen that my improved ornamental webbing consists of two complete plies or fabrics which are wholly independent of each other, excepting at the joining points 2', which extend lengthwise thereof, the term ply, as herein employed, being descriptive of a practically complete fabric rather than of a portion or partial thickness of a heavy fabric, as more commonly employed in the art.

By forming the ruffling or shirring from a complete ply or fabric independent of the elastic ply or fabric I avoid such exposure of the rubber warps as might result if a part of the non-elastic threads of the elastic ply or fabric were taken for the formation of a ruffling on the webbing.

It will of course be understood that my invention is not limited to the numbers of threads herein shown or to any particular stitch or pattern in the Weaving, as the two plies or fabrics may be woven either plain or figured, the essential feature of novelty of my invention being in the two independent plies or fabrics, one of which is woven fuller than the other and is wholly or mainly of nonelastic threads, an d which is ruffled or shirred by the contraction of the elastic warps of the other ply or fabric.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. The herein-described woven elastic fabric, composed of two independent plies or fabrics united longitudinally at one or more transverse points by warp-threads passing from one of said plies or fabrics to the other, one of the said plies having elastic warps disposed throughout its width and the other ply being woven fuller than the ply having the elastic warps, whereby it will be shirred or ruftled by the contraction of said elastic warps, substantially as described and shown.
