ELASTIC FABRIC.

Specification of leiuued Letters Patent. Reigsued Sept. 13, 1921,

02181181 In. 1,859,112, dated Iovember 18, 1920, Serial llo. 297,558, filed Kay 18, 1919. Application for fu lll hclear, and exact description.

is invention relates. to elastic textile fabrics the object being to produce a fabric adapted tobe made up into garments to be worn next to the body or over the underwear of the bod such for instance, as 'rdles, brassieres ends 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 ha suflicient stren and body to resist t e strained con ition under which such rmentsare 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 wh e it is possible to insert rubber cords by hand or otherwise into the meshes or of certain loosely knit or lacy fabrics,

loocps su fabrics have no practical use for pur- .ap ears in the fabric.

poses such as above mentioned.

The present invention rovides a way of associating rubber stran s with threads in such a mannerthat the rubber will be firmly pped by the threads to prevent it from oming dis laced in the fabric and the threads may dis osed in certain ways to produce the desire open work or porous pattern.

The fabric and the manner of making it will now be ex lained with referenceto .the accompanying rawing, in which Figure 1 is a face view of a piece of the finished fabric;

Fi 2 is a similar view of the same of fa ric as it a are in course of cation in the mac me, and

Fig. 8 is an enlar' view of one of the rubber cords covere by a chain stitch as it iece . he fabric comprises rubber cords or strands arran ed in arallel relation and spaced apart, t e individual cords being covered or mclosed in individual textile coverhugs and the adjacent cords being connecte abrireissue filed July 1,1821.

together by independent cross threads which interlock with the threads covering the cords and which are arran d in groups with intervening spaces. This individual covering on the cords can be put on with suflicient tension to prevent the rubber from slipping with respect to the cove-ring threads while the lateral or cross threads between the cords can be grouped or spaced as desired to afford the necessary porosity, without affecting the grip between the rubber and its covering. a n the process of making the fabric, which may be done on a 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 covering of the strand with which my invention deals. The latter covering is indicated by 2 and is preferably com osed 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 the back of the strand 1. One of the threads 2 is applied individually to each of the rubber strands and simultaneouslywlth the formation of the loops they are interlocked with cross-threads 3 which extend back and forth between the cover-lugs 2 of adjacent strands 1 interlocking with each. The cross-threads 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 stag red upon opposite sides of each cord ro ucin a checker board open effect in the abric. he loops inlthe threads 3 being arran d at ri ht ang es to the e grtension and contraction of the rubber strands, will readily open and close with movements of the rubber and w ll not oppose the stretching and contracting of the fabric. The spaces 4 between the groups of *1 cross threads are formed by carrying the last the direction of I the groups of loops a and the in whatis the equivalent run of thread in a group across the rubber cord to the opposite side thereof to form a .group on that side and againacross the same cord to the first side where another group is formed and so on. throughout the abnc, thus forming spaces alternating with and of the same size and shape. Referring particularly to Fig. 2, the fabric may be considered-,as formed of alternate cords, a, a, a, etc., and intermediate or other cords b, b, b, etc., between which the cross threads are mm. For example, the cross thread is run back and forth a number of times in close relation to itself between each of the alternate cords a nearest intermediate or other cord side thereof, the cross thread then passing across that alternate cord a and running back and forth a number of times in close relation to-itself between that alternate cord and the nearest intermediate cord 6 upon that side thereof, then across that b at one 'alternate cord and run as before alternating from side to side of each alternate cord to form alternate or staggered groups of open and closed spaces. The cross threads 'foreach alternate cord a arepreferably so arranged with respect to those of the adjoining alternate cords as to cause all of the open spaces on opposite sides of every cord e sta gered with respect to one another. Every a tcrnate cord a, a, (1, etc., is thus crossed by the loop threads 3 while the other cords b, b, b, etc.,

cords a. j a This fabric can be cut at any point and 1n any direction as may be required in the making of articles of wear without retrac- 1011 or shpping of the ru her; it may be made of any weight desired and may be given any degree of porosity to suit requlrements; it can be made on a machine at consequent low cost and the peculiar stitch affords a way of incorporating rubber of a knit fabric without liability of displacement of the rubber. a

I claim:

1. 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.

2. An elastic textile open-workfabric jac'ent cords and then are merely interlocked, w1th the tips of the loops carried by the 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 intervemng open spaces, the groups on one side of a cord being opposite an open space on the o posite side thereof.

4. An elastic fabriccomprising a series of parallel elastic cords spaced apart, a chain stitch covering for each cord, and

cross threads running back and forth in close relation between each alternate cord and the, next adjacent cords, the cross threads interlocking with the chain stitch covering and being repeatedly run back and forth a number of times in each space between an alternate cord and one of the adpassing to the opposite side of this alternate cord and belng repeatedly run a number of times between said alternate cord and the other next adjacent cord, alternatel staggered open spaces etween the cords, the arrangement of cross threads for each'alternate cord being such as to cause all of the open spaces on opposite sides of every cord to be stag red with respect to one another. a 5. An e astic 'fabric' comprising a series of parallel elastic cords spaced apart, and connected by cross threads running back and forth in close relation between each alternate cord and the next adjacent cords, the cross threads being repeatedly run back and forth a number of times in each space at one side of an alternate cord. then across that alternate cord and run back and forth a number of times side of that alternate cord, alternating from side to side to provide staggered open spaces between the cords, the cross thread for each alternate cord being disposed to form its groups of o en spaces in staggered relation to those of the next adjacent alternate cords.

In witness whereof I subscribe mysignature.
