This invention relates to knitted fabrics, and

yarn.

The stocking blank exemplified in Fig. 1 may have a shaped leg portion (not shown) produced in the well known way from a single yarn and terminating in an ankle portion A, the direction has reference more especially to fiat knitted 5 of knitting being indicated by the arrow in the selvaged fabrics useful, for example, in the procenter of the figure. Beginning with the course duction of full fashioned stockings and the like, 3-33, the fabric is progressively widened for a and characterized by having parallel edge portime by addition of end loops along each edge to tions as Well as widened and narrowed portions a course CC'-C2-C3,- with attendant forma' with inclined edges tion of the upper portions of projecting heel tabs Amongst the objects of my invention are to or cheeks at opposite edgesof the blank having avoid sleaziness in the selvages of fiat knitted inclined selvages B-C and B3-,C3.

This desiderata I attain in practice as knitted :in a suitable manner with an instep hereinafter more fully disclosed through a novel .20 portion I of 11I1if01'm W dt t9 t e line interlocking of the loops at the-selvages at the and with a tapered toe portion T therebey0nd. fabric edges.

I Other objects and attendant advantages will From Fig. 2, it will be noted that in the lower appear from the following detailed description parallel edged or'ankle part A of the fabric fragof the attached drawings, wherein 4n ment, selvage loops 4| are formed in the edge Fig. 1 is'a fragmentary view of a full fashioned wale 4 in alternate courses 2| and 23 from the stocking blank formed from a fiat knitted selmain yarn Y alone, and that in the penultimate vaged fabric conveniently embodying my inven- Wale 3 selvage loops 46 of the reinforcing yarn tion. v are doubled with plain loops 4'! of the main yarn Fig, 2 is a fragmentary detail view showing in the intervening courses Hand 24, while in the the exact formation of the selvage along the remainder of such fabric portion plain loops widened portion of one of the reinforced heel 42 of said reinforcing yarnare doubled with cheeks of the blank at the rectangle II in Fig. 1. plain loops 43 of said main yarn. In the first 4 Fig. 3 is a view similar to Fig. 2 showing a widened course 26 of the fabric in Fig. 2, a' slight variation in the selvage; and twisted loop 49 formed from one of the yarns,

Fi 4 is a view in turn ke 2 of i d in this. instance the main yarn Y, in the edge .fabric formed in acco dan Wi my ve i wale 5 is doubled with an untwisted loop 50 of. s a ringless S ructure by use in the knitting of the reinforcing yarn y, such selvage loop being three main threads together with a reinforcing locked by virtue 'of the passage of the main yarn Y through coincident sinkerwale loops 5| and 52 of both yarns. The next widened course 30,

has an untwisted loop 58 of the main yarn Y in the edge wale 1 doubled with a twisted loop 59 this instance the reinforcing yarn 3 through a sinker wale loop 60 formed from both yarns. Attention is directed to the fact that, in accordance with my invention, two extra end wale loops are added in the second step-out as distinguished from the addition of but one single loop in the first step-out in the course 26. Several

unwidened courses

21, 28 and 29 may be interposed between the widened

courses

26 and 30. In the course 21 it will be observed that the edge loop 53 in the wale 5 is formed solely from the main yarn Y, while in the next adjacent wale i in such course, a loop 55 of the reinforcing yarn y is doubled with a plain loop 54 of the main yarn. Beyond the widened course 30, the selvage loops 6| of the alternate uniform width courses 3| and 33 in the edge wale 1 are formed from the main yarn Y alone. In the intervening course 3 2, however, end selvage loops of the reinforcing yarn y are doubled with plain loops of the main yarn as instanced at 62. Beyond the course 33, it is to be understood that the double wale widening is repeated at suitably spaced intervals as often and to the extent desired or required, with maintenance of the above characteristic interlocking of the loops at the selvages.

The modified selvage of Fig. 3 is generally like the selvage of Fig. 2 except that in the second widening out course 30a (which corresponds to the course 30 in Fig. 2) an untwisted loop 590 of the reinforcing yarn y isfdoubled with an untwisted loop 58a of the main yarn Y in the edge wale In. It is to be particularly observed that one leg of the loop 59a passes through double sinker wale loops of the main and reinforcing yarns at 600 in the course 3la, and

that one leg of the loop 58a passes through a sinker wale loop of the reinforcing yarn only at 600. with consequent locking of the selvage against rav'eling at that region.

In Fig. 4, the three main yarns from which the fabric is produced as a ringl ess structure are designated respectivelyby the characters Y2, Y3 and Y4, and the yarn used in reinforcing by the character t2. As shown, the selvage formation of the fabric at the widened course 39b is similar to the selvage formation of the corresponding course 30 of Fig. 2 since it involves a twisted end loop 59b of the reinforcing yam g2 which is looked through passage of such yarn through an adjacent sinker wale loop 501), and which is doubled with a spread loop of one of the body yarns comprehending the two added end' wales of the fabric. A' slight variation will however be noted here in that the crosswise portionof the twisted loop 59b is within the sinker wale loop 60b and that the latter constitutes a loop inthe succeeding course 3lb. Except for longer skips of the main yarns at the selvages, the construction of the fabric of Fig. 4 isotherwise generally like that of Fig. 2. a

From the foregoing it will be seen that in all the illustrated forms of my improved knitted fabric, the selvages are effectively locked against the possibility of easy raveling. It will also be seen that byvforming the end selvage loops either throughout or in alternate courses from is considerably reduced with consequent preclusion of bulky seams when such edges are united by sewing.
