WOVEN ELASTIC FABRIC.

SPECIFIGATION forming part of Letters Patent No. 628,934, dated July 18, 1899. Application filed March 18, 1899. Serial No. 709,592. (No model.)

To all whom it may concern.-

Beit known that we, JOSEPH W. GREEN, Jr.,. and GEORGE AsTILL, 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 Woven Elastic Fabrics, of which the following is a specification, reference being had therein to the accompanying drawings.

Our invention has for its object to provide woven elastic fabrics which will be attractive and ornamental in appearance and in which without requiring proportional large quantities of woven fibrous threads the rubber threads or strands used in the fabrics will be well covered with fibrous threads either when the fabrics are in normal contracted position or when stretched and in which the rubber threads or strands will be so incased and bound in as to be well protected, so that they cannot slip in the fabrics when the latter are stretched and also so that they cannot contract or lose their positions relative to the woven threads when the fabrics are cut. To this end we incorporate in the bodies of our improved elastic fabrics oval or fiat elastic braids, in which the rubber threads or strands are incased or both incased and intertwined by braided fibrous threads, and these elastic braids may be employed either alone or in connection with raw or unbraided rubber warps or strands. These fiat or oval elastic braids give an attractive ribbed efiect to the fabrics in which they are incorporated and the rubber threads or strands thereof may, if desired, be incased or intertwined by fibrous threads of cheaper material than the material employed in the woven elastic fabrics. Thus in producing narrow ware or other woven fabrics of silk, cotton, or other material the fibrous threads of the elastic braids may be all cotton, while the warps and wefts of the woven fabric maybe of silk, cotton, or other material. In such case the cotton of the elastic braids will be covered by the silk or other material of the woven fabric in such a manner that less silk or other material need be employed in the fabrics to cover and protect the rubber than would otherwise be necessary. Furthermore, the fibrous threads inthe elastic braids afford a better frictional hold by the weft-threadsof the woven fabric on the rubber threads or strands when the fabrics are stretched or when out than would be afforded by a direct contact of the said weftthreads with said rubber threads or strands. a I

In the accompanying drawings, Figure 1 illustrates in enlarged diagrammatic view a small section of an elastic woven fabric embodying our invention and in which oval elas-' tic braids are employed in connection with raw or uncovered rubber warps or strands. Fig. 2 is a similar view illustrating a form of our invention in which flat elastic braids alone are employed, these flat elastic braids each comprising several rubber threads or strands incased and intertwined by braided fibrous threads. Fig. 3 is a view similar to Fig. 1, illustrating another form of our invention in which fiat elastic braids each comprising a single strand of rubber are employed in the woven fabric. Fig. 4: represents a piece of fiat braid'such as is incorporated in the fabric represented in Fig. 2.

In the drawings, a denotes oval elastic braids or elastic braids which are oval in cross-section, formedin the present instance by employing in each braid three rubber strands b, the central one of which is much larger than the outer ones, these rubber strands being incased and intertwined by braided fibrous threads 0 in the well-known manner of forming elastic braids. In Fig. 1, 1) represents raw or uncovered rubber threads or warps, which are bound into the fabric by the wefts d, but which may also, if desired, be bound in by binder-warps, as is usual in forming woven elastic fabrics. Filling-threads may also be employed in connection with these raw or uncovered rubber Fig. 3 represents another form of our improved elastic fabric in which relatively large rubber strands I) are ineased in fibrous braided coverings 0, these flat braids being interwoven by wefts d.

The different forms of the application of our invention shown by the drawings are only a few examples of many dilferent forms of elastic Woven fabrics in which our invention may be employed, as a great variety of modifications or uses of our invention is possible in all kinds of elastic woven fabrics-such as gorings, webbings, garterings, beltings, corset-webbings, loom-webs, &c.it being obvious that our invention may be employed in connection with any woven elastic fabrics Where an ornamental ribbed effect is to be produced or where it is desired to cover or protect the rubber threads or strands or bind them into the fabric in a strong and efficient mannerby a smaller quantity of woven threads than would be otherwise required. \Ve do not therefore wish to be understood as limiting our invention to any particular form or. arrangement in the bodies of woven elastic fabrics of the oval or flat elastic braids shown and described.

Having thus described our invention, we

or raw rubber threads or warps properly dis-.

posedbetween the elastic braids.

3. A ribbed woven elastic'fabrie having interwoven in its body portion flat or oval elastic threads or strands incased in braided fibrous coverin s of ehea- )er material than the O fibrous woven material ofthe fabric.

In testimony whereof we affiX our signatn res in the presence of two witnesses.
