Central Falls, R. poration of Massachusetts I., a cor- Appucauoa February 24, 1940, serial No. 320,529 1o claims. "(cl. cie-172) This invention relates to knitted fabrics and methods of knittingthe same and more particularly to lmitted fabrics, such as hosiery, having elastic incorporated in the tops thereof Ato provide self-supportingv stockings. Specifically vthe invention pertains to the incorporation .of elastic courses adjacent to the selvages of knitted fabrics, such as hosiery, to .prevent outward curling or rolling thereof.

The fabric now to be described may be knitted on a two-feed knitting fachine, such as ,that diagrammatically illustrated in St. Pierre Patent No. 2,131,720, September 27, 1938, at the auxiliary feed of which the elastic is fed to the needles in a manner hereinafter to be described and at the main feed of which a relatively inelastic thread or yarn, such as cotton, is fed to the needles likewise in the manner'now to be described.

When practicing the .invention on a two-feed machine having a. needle cylinder, the elastic yarn or thread E is fed to alternate needles and caught in the hooks thereof at the auxiliary feeding station for the course l. Continued rotation of the needles causes all the needles to engage the inelastic thread C in their hooks. The alternate needles, knitting the Wales as 2, 3, 4, 6 and 6, act to draw bights of loops of the thread or yarn C, as illustrated in Fig. 2 at the course "l, said bights or loops of the thread C being drawn through bights or loops of the elastic thread E which passed below the latches of alternate needles as the said alternate needles were elevated upon approaching the main feeding station. The intermediate needles that knit the Wales, such as 2', 3', 4' and 5', engage the thread or yarn C in their hooks. Continued rotation of the needle cylinder causes the needles vious course elastic loops to effect the knitting therein again to approach the auxiliary feeding station where the alternate needles that knit the wales 2, 3, I, 5 and 8 draw loops or bights of. the elasticthread through previous course loops of the thread C to effect the knitting of the course ,8. The intermediate needles that knit the wales 2', v3'. 4' and 5' pass idly by the auxiliaryfeeding station.` Upon again reaching the main-feeding station the alternate needles again draw bights or loops of the yarn C through preof the course d, whereas'the intermediate needles which are not elevated to clear their latches as they approach the main feeding station, again engage the thread or yarn C in their hooks to effect tucking. Continued rotation of the needle cylinder causes the alternate needles only to be elevated which causes the course 9 loops of the thread C on the said alternate needles to pass below the latches. The said alternate needles then again engage the elastic thread E in their hooks, depression of the needles then causing the loops of the elastic thread E to be drawn through the loops of course 9 to constitute course it. All the needles, in this revolution of the needle cylinder, pass idly by the main feeding station. The knitting of the courses ll and l2 proceeds in like manner, that is, with the elastic thread E being knitted through previous course elastic loops only at the wales knitted by the alternate needles, whereas all the needles pass idly by the main feeding station. During the knitting of the following' course i3 the elastic thread E is knitted by the alternate needles at the alternate feeding station as before, but as the needles approach the main feeding station-they all are elevated to cause the loops hanging on the latches thereof to pass below the said latches, e. g., elastic loops of course I3 on the alternate needles and the cotton loops of courses 'l and 9 on the latches of the intermediate needles. Then all of the needles engage the yarn C in their hooks and draw bights or loops thereof through the stitches that have just been caused to pass below needle latches thus effecting knitting of the course I4. The knitting of the courses just described, constltute the selvage and an anti-curl or roll portion indicated at I5, Fig. 1.

Following the knitting of the course Il, other elastic carrying courses I6, that is, courses in which elastic yarn is incorporated to be held, may be knitted in the manner similar to that disclosed in the St. Pierre Patent No. 2,131,720 or in any other desired manner. The courses I6 an elastic yarn incorporated therewith constitute the rib top of the stocking shown at R, Fig. l.. While the invention herein disclosed is primarily vdirected to the selvage and anti-curl courses I5, lpreferably this part I of the stocking top, is

followed by a continuing portion of the top 5 knitted with elastic thread or rubber incorporated therein in such a manner as to simulate rib knitting, i. e., rib tops lmitted on two sets of needles. The remaining portion of the stocking. such as the leg I'I, heel I8, foot i9, and toe 26, may be l0 knitted in any desired manner. Furthermore, the top of the stocking may be knitted on one machine and secured in any desired manner to a separately knitted leg and foot of a mans, childs or womans stocking. The separately knitted stocking may be made upon an independent needle machine or upon a so-called fullfashioned machine.

The method of knitting, as hereinbefore described, has had particular reference to the fabric illustrated in Fig. 2. The welt effect of such a top is illustrated in Fig. 3, the elastic courses IU to i3 assuming a position on the inside of the stocking, the elastic constituting the courses I and 8, or in other words, that incorv porated to be held in inelastic yarn course 1, being on the outer face of .the stocking.

In Figs. 2 and 3 the fabric has been illustrated in its undistorted condition. The knitting of the tuck stitches at the wales 2', 3', 4' and 5,rf3"0 and the knitting tension imposed upon the elastic thread E during knitting, distorts the fabric from that shown in Fig. 2. Fig. 4 shows a few wales and courses of the selvage courses as they appear when distorted due to the knitting of the v`:3,5 tuck stitches and the tension upon the elastic threads. However, even in Fig. 4, to avoid the showing of solid black it has been found necessary to illustrate the elasticV loops, that is, the drawing of elastic stitches through previous` course elastic stitches, and also to illustrate the elastic iioats as spaced. Actually the spaced elastic courses ID, II,` I2 and I3 draw together until the elastic is actually in contact or nearly so especially at the intermediate wales 2', 3', 4' and 5 across which the elastic strands iioat. Even at the alternate wales the elastic through elastic loops draw together into nearly straight lines. The adjacency of the stitches of the elastic strands is illustrated in Fig. 5. The elastic course I straightens out in the completed stocking, as illustrated in Fig. 4.

As illustrated in Fig. 5, the elastic strands constituting courses Il), II, I2 and I3, are-'in contact or nearly so, forming a bead which is quite noticeable on the inside of a completed stocking, this bead of elastic having the effect of tending to pull the course 9 over to the inside of the stocking thus resisting any tendencyv of the stocking top to roll or curl outwardly. Thus '60 the elastic courses I0, II, I2 and I3 eiect the knitting of a welt which does not tend to roll or curl outwardly, furthermore, the welt effects a stiffening and strengthening of the selvage. Knitting tuck stitches at the intermediate wales in conjunction with the alternate knitting of elastic and inelastic yarns at the alternate wales, effects the knitting of a scalloped or picot edge.

As illustrated in Fig. 6, the top of the stocking curves inwardly, as indicated at 2l, thus further 70 resisting the outward curling tendency of the top of a stocking knitted with cylinder needles only.

Whereas a single group of exclusively elasti courses I0 to I3 inclusive, has beendescribed 75 and illustrated, modifications thereof may be adopted, e. g., a group of elastic courses, like IU to I3 inclusive, may follow course I4, the needles knitting the intermediate wales 2', 3', 4' and 5' in such a case again tucking at the main feeding station in the course following course I3 while the needles that knit the alternate wales as 2, 3, l, 5, 6 pass idly by the' main feeding station. Flolligviii courses are knitted as the courses I0.

From the foregoing description it will be evident that the selvage is knitted with plain wales as distinguished from rib Wales knitted with two sets of needles and further that the method of knitting hereinbefore described causes the top of the stocking to be drawn to the inside thus restraining the tendency of a plain knitted selvage to roll or curl outwardly.

While, for convenience, the stocking top has been described as having been knitted on a circular series of needles which have independent movements, it is evident that the knitting of the stocking is not restricted to such a machine. Furthermore, the terms employed have 'been used for descriptive purposes only and not in a limiting sense.
