ELASTIC WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 436,872, dated September 23, 1890.

Application filed November 6, 1889. Serial No. 329,404. (No specimens.)

To all whom it may concern.-

Be it known that we, JOSEPH W. GREEN, J1., and EDMUND H. SAWYER, citizens of the United States, residing at Easthampton, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in ElasticNVoven Fabrics, of which the following is a specification, reference being had therein to the accompanying drawings.

In certain classesof elastic fabrics it has been found desirable to have at the edges thereof rubber warps, which are covered by the weft-threads only, these rubber warps atthe edges of the fabrics preventing cockling or puckering of the fabrics by drawing up the edges of the fabrics the same as the central portions thereof; but the use of these weft-covered rubber warps at the edges of the fabrics has been attended with some objections, as they are not sufficiently protected to stand much wear.

The object of our invention is to obviate this objection; and we accomplish this object by incasingthe edge rubber warps in a covering of braided fibrous threads, and then weavingthese covered rubber warps into the edges of the fabrics in the same manner that the noncovered edge elastic warps were woven inthat is,by engaging them by the wefts only.

In the accompanying drawings, Figure 1 is a diagrammatic View representing, in enlarged cross-section, a portion of an elastic fabric vember 30, 1875, is covered by the weft only,

is, according to our invention, first incased in a braided covering 0 of fibrous thread, and is then woven into the fabric by the passage of the weft-threads around it, as in the patent just above referred to. The braided covering 0 in connection with the weftthreads, fully protects the edge rubber warps, so that they will relnainintact during thelife of the fabric, the edges of which, owing to our improvement, will stand as much wear as the bodies thereof.

Having thus described our invention, we claim- An elastic fabric provided at its edges with elastic warps covered with braided fibrous threads, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
