ELASTIC FABRIC.

Application filed in, 1a, 191a. Serial No. 297,558.

Elastic Fabrics, of which the following is a full, clear, and exact description. V This invention relates to elasticctextile' 10, fabrics, the object being to produce a fabric adapted to he made up into garments to be worn next to the body or over the" under' wear of the body, such for instance, as

girdles, brassieres, bandages and so forth. or such purposes it is desirable that the fabric shall not only be elastic, but that it shall be more or less open in structure, or porous to afford ventilation, while at the same time having sutlicient strength and body to resist-the strained condition under which such garments are used. Open work or porous fabrics are seldom, if ever. made with elastic cords incorporated therein because the cords will not be held from slipping by the texture of such fabrics, and while it is possible to insert rubber cords by hand or otherwise into the meshes or loops of certain loosely knit. or lacy fabrics, such fabrics have no practical use for purposes such as above mentioned.

The present invention )rovides a. Way of associating rubber "strands with threads in such a manner that the rubber will be firmly gripped by the threads to prevent it from becoming displaced in the fabric and the threads may be disposed in certain ways to produce the desired open work or porous pattern.

The fabric and the manner of making it will now be explained with reference to the accompanying drawing. in which- Figure 1 is a face view of a piece of the finished fabric;

Fig. 2 is a similar view of the same piece of fabric as it appears in course of fabrication in the machine, and Fig. 3 is an enlarged view of one of the rubber cords covered by a chain stitch as it, appears in the fabric. The fabric comprises rubber cords or strands arranged in parallel relation and spaced apart, the individual cords being oovere'dfl'or inclosed in individual textlle coverings and the adjacent cords being bfi l'connecfled together by independent cross threads which interlock with the threads covering the cbrds and which are arranged in groupswith intervening spaces. The indivldual covering on the cords can be put on with sufficient tension to prevent the mbber from slipping with respect to the covering threads while the lateral or cross threads between the cords can be grouped or spaced as desired to afford the necessary.

porosity without afl'ccting' the grilp between the rubber and its covering. n the process of making the fabric, which may be done one warp knitting machine, the rubber strands are held in a considerably extended condition so that when finished the natural contraction of the rubber will draw the threads together and give body to the fabric.

In Fig. 3 a short length of one of the rubber cords is shown on an enlarged scale, wherein 1 indicates the rubber strand which may be understood as naked rubber or as rubber having a winding of cotton. Such a Winding, however, if provided is not to be confounded with the coveringof the strand with which my invention deals. The latter covering is indicated by 2 and is preferably composed of a single thread wrought into a chain stitch as shown, the loops of which embrace or surround the rubber strand 1, the dotted lines indicating that part of the thread which passesaround the hack of the strand 1. One of the, threads 2 is applied individually to each of the rubber strands and simultaneously withflihe formation of the loops they are interlocked with cross-tl'u'cads 3 which extend back and forth between the coverings 2 of adjacent strand.- 1 interlocking: with each. The rross-thrcsuls 3 which may be double, although shown single, are thus arranged in successive loops between the adjacent rubber strands. These loops are laid in groups with intervening spaces 4 and are staggered upon opposite sides of each cord producing a checker board open effect in the fabric. The loops in the threads 3 being arranged at right angles to the direction of the extension and contraction of the rubber strands, will readily open and close with movements of the rubber and will not oppose the stretching and contracting of the fabric. The spaces 4 between the groups of cross threads are formed by carrying the last run of thread in a group across the rubber cord to the opposite side thereof toform a group on that side and again across the seine cord to the first side Where another group is formed and so on throughout the fabric, thus forming spaces alternating with. the groups of loops and of the same size and shape. Eveother cord as a, a, a, etc., is thus crossed gy the loop threads 3 while the alternate cords b; b, b, etc, are merely interlocked with the tips of the loops carried by the cords w.

This fabric canbe out at any point and in any direction as may be required iii-the making of articles or wear, without retraction or slipping of the rubber; it may be made of any weight desired. and may be given any degree of porosity to suit requirements; it can be made on a, machin it conse uent low cost and the peculiar stitch afl'or s a way of incolgmrating rubber in what is the equivalent 0 a knit fabric with out liability of displacement of the rubber.

I claim:

I. An elastic textile open'work fabric comprising a series of parallel elastic cords spaced apart, an indiv dual textile covering for each cordand cross threads connecting open spaces.

2. An elastic textile open-work fabric comprising a series of parallel elastic cords spaced apart, on individual textile covering for each cord an-:l.cross threads connecting the coverings of adjoining cords, said cros threads being run back and forth. in close relation forming groups. with intervening open spaces, the groups on one side of a cord being op osite an open space on the opposite side t ereof.

3. An elastic textile open-work fabric comprising a series of parallel elastic cords spaced apart, an individual textile covering for each cord and cross threads connecting the coverings of adjoining cords, said cross threads being run back and forth in close relation forming groups with intervening open spaces, the threads composing the groups on the opposite sides of alernate cords being utinuous.

In witness whereof I subscribe my signature.
