16 Claims.

`This invention relates to elastic fabrics such as braided bands and the like, and more particularly to a new and improved method of producing such fabrics.

In the past, a number of difficulties have been experienced in producing elastic lace-braid bands having varied and attractive designs therein. This being especially true of such bands having a. straight bar effect in their design, as produced by the .longitudinally extending strands. When produced by methods different from the one herein described, the defects common to such materials,l namely, creeping, bunching, slipping, etc., of the yarns, could be obviated only With con- VSider-able difficulty and excessive expense;y

With this inview, it is an object of the invention to produce novel elastic lace-braid bands, which overcome the mentioned and other difiiculties.

It is also an object of this invention to produce elastic lace-braid wherein the transverse binding threads are never placed under any excessive tension even though the elastic longitudinal strands may be stretched to their elastic limit.

A still further object of this invention is to produce elastic lace-braid which has a minimum of latitudinal or sidewise contraction even though the elastic strands be stretched excessively in` a longitudinal or lengthwise direction.

A further object of this invention is to produce an elastic braid wherein the laterally extending threads are prevented from creeping -and causing a bunched appearance in the fabric.

Another object of the present invention is t9 produce a novel elastic lace-braid fabric or band having elastic strands extending longitudinally thereof, which strands are inter-locked with each other and with other strands of the braid structure to insure the permanency of relationship between the elements in the shape and form as braided, i. e. the several strands in the braid structure are so intertwined that no single one or a. number of the strands may be pulled longitudinally to any extent.

Another object is to produce inexpensive and effective, yet beautifully designed, elastic-braid bands having all of the above and other advantageous elements and features, and which are particularly adapted for use as garter tops or 'elastic welt units for hosiery.

Another object of the invention is to provide an elastic braid having a. distinct border design which is 'not only concerned with the attractive appearance of the article, but in which such edge presents a readily discernable topping on line adapted to facilitate the attachment thereof to the knit loops of a stocking.

It is another object of this invention to produce such elastic-braid bands in designs comprising a repeated pattern having dense center por- 5 tions separated by open lace-like center portions, both of which are centrally positioned by pillarlike strands extending perpendicularly from longitudinally extending border portions.

A still further object is to produce novel lace- 10 braid fabrics or bands in which the design will be relatively unchanged even though the band is fully extended; the only effect of extending the band being to produce a slightly more open and loose-course structure, still retaining, however, the basic features of the original untensioned band.l

It is also an object to produce a novel braided l fabric of this type, wherein the extension of the Aband is accompanied by a practically equal extension of both the dense and the opencenter portions with very slight, if any crosswise contraction of these center portions, the lengthwise stretch of the braided band being .effected bystretching of the longitudinally extending elastic pairs of strands, which strands are kept parallel for a fixed portion of their length and are then concurrently intermittentlyr intertwisted within a givenstrand pair for the production of a lacelike or open work effect in the center portion 3,0V

of the band. J

, In addition, it is an object of this invention to produce such elastic lace-braid bands by an improved method and to simultaneously embody within the braid, non-elastic binder strands, sin- 35.1v

gly decussated and yet completely effective in holding the elastic strands and inelastic strands against movement and/or creeping relative, both to each other and to the body of the braid fabric and yet only very slightly, if at all, to 40 effect limiting of the longitudinal or lengthwise stretching qualities of the fabric. It is also to be noted that ornamental designs and open mesh or lace forms of considerable beauty are possible and may be effected by utilizing this method of .manufacturing braided fabric, which designs could not heretofore be produced.

With these and other objects in view,' which will become apparent from the following detailed description of the illustrative embodiments of thereto.

. According to the invention, the improved elastic lace-braid may be manufactured by any of the well-known lace braiding machines which may be governed in their design producing effects by the familiar jacquard mechanism which in turn controls the travel of the various carriers about one or more tellers or quoits, and thereby forms the finished fabric. The operation of the jacquard mechanism is so well-known to those versed in the related art that no description of it is deemed necessary here.

Referring now, more particularly to the diagrammatic pattern illustration shown in Fig. 3, II represents the tellers or quoits which are rotated under the control of the ordinary jacquard mechanism, causing the bobbins or yarn carrier's diagrammatically indicated at I2 to traverse the race-courses. AIn accordance with the mechanism, some of the bobbins I2 will be idle still others will course one teller, while other: will course or traverse the whole series of tellers.

In the pattern shown in the figures, and par- 5 ticularly more clearly shown in Fig. 3, the strands I3, I4, I5, I6, indicated by the heavy lines may be cotton or silk covered elastic bersor even bare rubber strands and, as usual, are especially tensioned or held taut so as to increase their 10 length during the braiding operation. It is to be noted, that at portions such as til, 52, 53, pairs of elastic strands, e. g. pairs I5, I6; pairs I l, I8,

lare interchanged or twisted, and are themselves intertwined with other elastic or inelastic yarns 15 or strands whereby to prevent these elastic strands from being pulled-out longitudinally of the braid.

The strands which are designated in the drawings by numerals 3| to 44 inclusive (see particu- N larly Fig. 3) may be either other elastic strands pf a, different gauge than the elastic strands I3, I4, I5, I6, etc. cr inelastic strands, and these strands 3| to 44 are, as is customary in braiding apparatus, carried by the spindles I2 and caused 3| to form the pattern together with such other elastic strands, also on other spindles I2.

In producing the pattern illustrated in Figs. 1 to 9, the bobbins I.2 carrying elastic strands I3, I4, interbraid their strands with the other strands While they themselves remain rotating each on 4its own teller only. Bobbins I2, carrying strands I5, I6, I1, I8 interbraid their Ystrands with the other strands and remain rotating each on one teller for a portion of the tine and then both cross over and within pairs mutually interchange tell'- ers, the one with the other at a predetermined point in the fabric.

Bobbins I2,l carrying strands 32, 34, 35, 36, 31, 38, 39, 40, 4| and 43, will be seen to traverse at 40 some time or another each and/or'every teller on the braiding machine.

In order to more clearly follow out the course of the inelastic or elastic. transverse strands, one

of the same, denoted by letter X has been shaded in Figs. 3 and 5. f

' The various threads, both elastic and inelastic threads, are similarly numbered in all the drawings Figs. 1 to 8 inclusive. The structural de.,- tails of the novel elastic lace-braid and its method of attachment to, and integral knitting with, the stocking b ank, are very clearly shown, and more particular so in the extended or stretched views of the elastic fabric. For this reason, mere reference to the diagrammatic view of Fig. 3 together 55 with any one of the extended or stretched views of the nished and correspondingly designed article is believed to clearly-and adequately disclose the complete details of the invention.

However, in order to further facilitate an understanding of the invention herein involved, the

.rst course of the stocking is indicated by letter a". This course is produced on the needles of a straight or full fashioned stocking knitting machine after the new and improved braid has been topped onto said needles, in the well known manner, the openings, indicated at 6|, 62, 63, etc. at the edge of the braid being particularly adapted 'for the transfer operation. It will be seen from an inspection of Figs. 6 and 7 that the number 70 of interstices at such braid edge correspond with the number of loops coursewise of the stocking; hence, providing an extremely efficacious medium for the attachment of a braided top to knitted stockings,

Figs. 9 and l0 show an improved elastic lacebraid having a picot edge b and an improved topping edge ccomprising inter-lace braided edge which may be topped, through openings |6I,

|62, |63, etc., on the needles of the stocking knitting machine.

In the form of the invention shown in detail in Figs. 9 and 10, there is provided a braid having a topping edge especially adapted to cooperate with the instrumentalities used in a topping-on operation; also, this new braid has been devised with a view to a more permanent non-slipping arrangement between the elastic and other elastic or inelastic threads at its edge. In the operation of topping a stocking with elastic braid, the latter is usually stretched prior to its attachment to the transfer bar and subsequently to the knitting needles, which not only spreads the openings IBI, |62, |63, etc., to facilitate positioning the transfer points or needles therein, but affords the correct amount of contraction in the top of the finished stocking. In the usual types of elastic braid wherein the elastic strands are merely laid straight and held from longitudinal slippage only by the crossing therewith of inelastic threads, when such braids are stretched considerable care must be taken to grip all the strands at each end thereof to prevent the dislocation of the elasticstrands. If these elastic strands are deranged from their original position in the braidit results most times in the destruction of such braid for use.

As best seen in Fig. 10, the elastic strands |50, |5| at the topping edge of the braid are crossed with each other and interbraided with inelastic strands |0|, |02, and by such construction the braid is insured against any of the usual difliculties which occur during handling.

V.[t is to be noted that this invention involves a novel lace-braid and a novel method of knitting a stocking integrally with an edge of an elastic lace-braid. It is to be further noted that this method of integrally knitting a lace-braid and a stocking is not limited to its use on a straight or full fashioned stocking knitting machine, whether for stockings or for other knitted fabrics wherein an elastic member would be a desirable element.

It will appear from the foregoing that the several illustrated and described embodiments of this invention are directed to braids composed of a plurality of elastic and inelastic strands which are arranged in the new and improved manner to provide stretch only in the longitudinal plane thereof, these particular illustrated embodiments being adapted to serve as welts for stocking tops, in which use it is preferable t0 have elasticity oniy transversely of the stocking. This, however, is not to be construed as limiting to the invention, asthe new and improved braid may well. be constructed to provide both longitudinal and transverse stretch and still retain all of the herein disclosed novel features, e. g., an open mesh beautifully designed elastic braid to be used as stocking top welts, and having a spaced selvedge presenting a readily discernable topping-on line in braids of this type, or an elastic braid for use in underwear or other articles wherein it is desirable to havean elastic element capable of beingl stretched in more than one direction.

Of course, the improvements specifically shown and described, by which I obtain the above results, can be changed and modified in various ways without departing from the scope of the invention herein disclosed and hereinafter claimed.
