Patented Sept. `23, 1941 KNITTED FABRIC AND METHOD Wiliam L. smith, Jr., Pawtucket, n. I., assigner to Hemphill Company, Central Falls, R. I., a corporation of Massachusetts Application September 5, 1939, Serial No. 293,395

4 Claims.

This case deals with knitted 'fabrics in which elastic yarns have been incorporated in a manner to rcomplete a selvage and thereafter, to render the fabric elastic generally.

In the figures of drawing:

Fig. 1 is a conventional representation of a section of fabric, loops being shown greatly enlarged;

Fig. 2 is an elevation of a half hose towhich the invention may be applied; and

Fig. 3 is an elevation of a stocking top of slightly different types wherein the invention may be applied.

Referring to Fig. 1 an elastic yarn, preferably fed at an independent feeding station in a two feed knitting machine such as a hosiery machine, is taken in the hooks of every fourth needle such as would knit in wales 2, 3, 4 and 5. It is to be understood that at this time the feeding -of this elastic is merely for the purpose of loading it within hooks of needles and there is no provision for clearing latches nor castingy loops from these needles until a later time( At the main side of the machine at which it is preferred to feed a non-elastic yarn or yarns no' knitting is being done so that in effect, that part of the machine is relatively inactive. Then for three revolutions more or less, said elastic yarn is taken in the hooks of every intermediate fourth needle, that is, those needles knitting in wales 6, 1, 8, etc. At this time four courses have been loaded, one in the hooks of the first mentioned needles and three in'the hooks of those second mentioned. It is to be understood that the elastic is fed under slight tension. When released it will contract and straighten out, then appearing as several stretches of elastic threaded through sinker loops or a following course.

The elastic yarn is then fed to every second needle and is drawn into knitted loops in course A, casting off the previously held elastic. Thereafter two courses of non-elastic yarn 9 are fed (ci. tss-172) side and by knitting the nen-elastic yarn et every needle at the main side.

. While that type of fabric is preferably knitted in continuation of the selvage and intervening course or courses such as C, other types of garter top may be knitted in which the elastic will beknitted, inlaid, or otherwise incorporated at spaced walesso as to draw those wales together tosmulate a rib appearance and to constitute the stocking top as a' garter. i

In Fig. 2 a half hose is shown to which the in- Vvennen may be applied, the top In being knitted in a manner described above, the selvage Il 'oe-- garter top as may be found most satisfactoryto prevent rolling of the fabric.

Referring to Fig. 3, the invention may be ap-l plied to a fabric in which that portion of the top indicated at I3 is knitted as illustrated in Fig. 1 while apart of the top at Il is to be knitted similarly except that the elastic is to be drawn into independent stitches vat more widely spaced wales and knitted at the so-called main side of the machine, these resulting in the courses B and C.

This completes a selvage and gives the course C as a sort of anti-curl or anti-roll barrier before elastic is again introduced to be incorporated in some desired manner throughout the remainder of the stocking top thereby to produce a garter;

From this point it is preferred to knit the elastic f i knitting a selvage having a course of elastic yarn-` than ever-y other Wale. For example, the elastic might be knitted on every fourth-needle or every sixth needle. The non-elastic zone as at l2 may also intervene between an edge l5 and the zone I4. The invention is defined inthe appended.

claims.

I claim:

1. Aknitted stocking top having a selvage including an elastic course drawn into knitted stitches at every second Wale and having incorporated therein several stretches ofy elastic, these being held by being threaded through sinker wales of said course of elastic, some through sinker wales adjacent spaced stitches and others through sinker wales adjacent stitches intermediate those spaced stitches. y

2. A knitted fabric having a selvage including elastic, several stretches of which have been loadled in predetermined wales and a final course drawn into knitted loops at every second wale, a plurality of non-elastic. yarn courses following said final course of elastic, thereafter a plurality of courses in which elastic and non-elastic yarns are knitted to form 'a garter top.

3. A methodfof knitting including the steps of and several stretches of elastic threaded through the non-elastic and elastic material knitted simulsinkerloops of that elastic yarn course, then knitting a plurality of courses of non-elastic ma.- terial without elastic incorporated therein, and

slight tension and at spaced wales.

^ Y 4. A method oi.l knitting as in laim 3 wherein taneously are first knitted through a zone in which the elastic is incorporated at Wales relatively widely spaced and then throughout a continuing portion of the stocking top at more closely spaced wales.
