' - important object oi the present invention is to eliminate or minimize the possibility oí the quality or appearance oi knitted fabric, articles or garments being impaired 'oy the production therein' of undesirable lines due to inequalities or variations in the size and/or shade of the yarn employed in knitting the articles; said lines, in the case oi ladies’ toll-fashioned iine gauge silk stockings made on a Cotton’s patent or like straight tar machine, usually appearing in the îorm of rings. 'it has heretofore ‘been proposed, with the ob ject oí minimizing this defect in the production function as a ground thread on some courses and as a stitch-locking thread on other courses. The improved knitted fabric or garment may be of the kind which is rendered ladderproof or ladder-resistant by the incorporation of Ul stitches that are locked or tied by the introduc tion of stitch-locking thread additional to the stitch-forming thread. Advantageously, al though not necessarily, locking or tying of the stitch loops is eiîecœd by passing a thread loop through and also around or over another loop, . or, in other words, by >completely encircling each side har or leg of- a stitch loop with locking thread which also extends from one side to the other of said loop. ' For the purpose oi more fully describing the 'nature oi this invention reference will now he made to the accompanying drawings, wherein: lï'igs. i to 6 illustrate six embodiments of im of stocb'ngs on a straight har machine, to knit a succession oi groups oí stitch courses ci which proved iabricaccording to the present invention. 20 each group is composed of successive courses each knit from a diñerent thread, i. e. a `thread drawn :trom a separate supply; and in this way thread miring is eñected, that is to say threads of the same colour and character taken from diüerent supplies, and no two successive courses vare lrnit írom the saine thread at that part of the stoch plies. in the construction shown in Fig. 1 four threads drawn from different supplies are in ì ing where the ini?ng is edected. The fabric or articles in this invention has 30 incorporated therein stitches that are locked or tied by the introduction ci stitch-«locmng thread additional to the stitch-‘forming thread, thereby eliminating or reducing the possibility of stitch iaddering or running; and according to the pres« 35 ent‘invention a knitted i’abric or article of this kind produced on a straight har knitting machine is provided composed of two or more threads and in which diñerent threads, (threads drawn from diner-ent supplies) íunctioning either as ground 40 thread (stitch thread) and/or stitch-locking in every case the fabric is composed of two different or distinct threads, i. e. threads of the same kind and shade drawn from different sup corporated, three ci said threads a, h and c he ing employed as ground or stitch-forming threads, hereinafter referred to as ground threads, and the fourth thread d being employed as a stitch-locking thread. Stitch courses are iormed in succession írorn the three ground threads a, b and c and the stitches in each course are ioclred by one and the same stitch-locking thread d. ‘ . in. producing this fabric on a Cotton’s patent or similar straight bar knitting machine, such as is employed in the production ci full-fashioned stockings, four thread carriers or guides operate over each section of the machine, each carrier receiving thread from .a separate supply, and all the threads being advantageously of the saine kind in every respect. Three oi the carriers opn thread, are laid in successive knitted courses. In this way a ladderprooi or ladder-resistant ` crate to lay the three ground threads o, b and c, knitted fabric knitted on a straight bar machine provided wherein different threads appear in 4Ul successively knitted courses as ground threads and/or as stitch-¿locking threads, and the threads in the fabric are thereby effectively mixed so as to eliminate or u' ». 5O irregulari ties in the :finished fabric as aforesaid. The particular construction of the fabric can while the fourth carrier operates to traverse the stitch-locking thread d. One carrier supplied with the thread a is ñrst traversed across the needles which are then operated to produce the ñrst course l of knitted stitches in the customary manner, said carrier being retained at the end of >its traverse. The carrier supplied with the locking thread d is then traversed to lay its thread _and the needles are operated to produce therefrom locking loops about the ground thread be varied in many ways within the ambit of the present invention.Y For example, the- fabric or article maybe composed of two or more threads Stitches in course I. The carrier supplied with the second ground thread b is then, traversed to 55 55 and each thread oi at leest two threads mayr 2 2,120,181 make a second course 2 of stitch loops inter linking with the stitch loops in course I, and the courses, and each thread being subsequently traversed in an opposite direction as a locking carrier appertaining to this ground thread b is l thread to lock the stitches in a subsequently retained at the end of its traverse. The carrier knitted course. In this case, however, instead supplied with the locking thread d is then trav of returning a thread laid as a ground thread ersed back across the needles in an opposite di in one course to lock the stitches formed from rection to lock the stitch loops in course 2, after Which the ground thread carrier supplied with the thread cis then traversed to form a third course 10 3 of ground thread loops interlinking in the customary manner with the stitches of the last produced course 2, and the carrier supplied with the locking thread d is then again traversed in îa reverse direction to lock the stitch loops in said 15 third course 3. After this the before-described movements are repeated by ñrst traversing the ground thread carrier supplied with the thread a to produce course 4 of stitches which are then locked by traversing the carrier supplied with the 20 locking thread d, this being followed by the trav erse of the carriers to lay the ground threads b another ground thread in the next succeeding course, each thread is returned to lock the stitches in the next but one succeeding course. In other words, assuming that courses I, 2 and 3 10 of ground thread stitch loops are produced re spectively from threads q, r and s, the thread q forming course I is subsequently traversed in a reverse direction to lock the stitches in course 3, whilst the thread r forming course 2 is returned to lock the stitches in course 4, and the thread s forming course 3 is returned to lock the stitches of course 5, and so on throughout the fabric. In the further modification illustrated in Fig. 6 three distinct threads t, u, v are employed. In 20 this construction, however, each thread is first and c; it being understood that after each course laid ln 'one direction to produce a course of of stitches has been produced the locking thread d ground thread loops and is immediately returned is traversed to lock said stitches.

When course I has been produced tioning to lay three different ground threads, ’rom the thread t, said thread is returned as a e, f and g, and the remaining three carriers locking thread to lock the stitches in said course. functioning to lay three different locking threads The second thread u is now traversed to form 30 h, i and y'. The production of this fabric shown course 2 of stitch loops interlinking with the loops in Fig. 2 is similar to that described with refer of course I and said second thread u is immedi ence to Fig. 1 except that instead of laying the ately returned to lock the stitches in this course. same locking thread at each successive course, the The third thread v is now traversed to form a three distinct locking threads h., i and y' are sepa third course of interlinking stitches, said thread v 35 rately and sequentially laid at successive stitch being also returned to lock the stitches in said courses; consequently each group of. three suc third course.

It will, of course, be appreciated are employed and selectively laid to form suc that the number of threads successively laid to cessive stitch courses, each course being> locked produce ground thread stitches and to lock said by one and the same stitch-locking thread d, stitches may be varied as desired. For example, in Fig. 3 one and the same ground thread Ic is `only two such threads may be employed and 50 traversed by one and the same carrier to and fro traversed alternately. to produce successive courses of stitches, while In fabrics according to the present invention three carriers supplied with three distinct stitch where a plurality of different or distinct ground locking threads l, m and n are operated in suc threads are employed and the locking thread or cession to traverse their threads and lock the threads is or are retained throughout the fabric 55 stitches in successive courses. as a locking thread or threads, the latter may be Figs. 4 and 5 illustrate examples of fabric com- » posed of two or more different or distinct threads in which each thread of at least two threads functions as a ground thread on some courses and 60 as a stitch-locking thread on other courses or vice versa. In the construction shown in Fig. 4, two threads o, p are employed, each thread func tioning at one stitch course as a ground thread > and at the next succeeding course as a stitch locking thread, the thread change being, there fore, effected at successive courses. In kother appreciably iincr than said ground threads and consequently less conspicuous in the ñnished fabric. In such case, however, it must be borne in mind that diiferent ground threads are laid at _successive courses. From the above it will be appreciated that in any two consecutive courses> of stitches diiferent threads are employed either as ground threads or locking threads or both, consequently the thread change from one course to another effec 65 tively eliminates or minimizes striping or ring words, each of the two threads o, p is laid on ^ effects in a knitted fabric or article such as a alternate courses as a stitch-forming thread and stocking.
