Serial No. 708,937. Original No. 1,096,566, 1914, Serial No. 841,394. This application To all whom it may concern:

Be it known that I, Bonner W. Soo'r'r, a.

citizen of the United States, residing at.

Boston, in the county of Suffolk and State ofMassachusetts, have invented a new and useful \Velted Knitted Web and Method of Making the Same, of which the following is a specification.

The object of my invention is to prov de a knit structure suitable for the end finish of circular knit webs such as stocking legs, whichobject I attain in the manner hereinafter set forth, with reference to the accompanying drawings in which- Figure 1 is a View of a stocking provided with my improved welt structure. Fig. 2 is a view on a larger scale of the fabric structure. Fig. 3 is a sectional Figs. 4 to 10 are diagrams illustrating the formation of the fabric of the welt.

This application is a division of my application Serial No. 552,002, filed March 28th, 1910 (Letters Patent No. 1,045,620, dated Novemberlfi, 1912), in which I disclosed a stocking having an integral turned welt produced by the operation of one set of needles only, and therefore capable of being made upon a circular stocking knitting machine without the use of dial needles or transfer implements. not claimed, when a short, bunchy welt is required the loop retaining needles, which may be merely-alternate needles or some of the needles of the circular series, may be retired out of action while they are in a projected position, the other needles remaining in action to produce welting courses, so that the sinker wales of said subsequently produced welting courses will .all be caught and retained by said retired needles and will thereafter be cast off as a unit when the formation of the welt is completed and the stitches for the remainder of the'leg'tube are being drawn. A welt of this character contains only a portion of the number of wales of knitting contained in the leg tube.

.In order to produce a stocking according to my invention, it'being understood that the usual process of manufacture will involve the making of complete stockingsthat is, complete except for the closure at view showployed insa-id courses crossing As therein disclosed, but

the top of the toe thereof-I employ a knitting machine having a needles half of which may be retired from action while heel and toe pockets are knit by narrowing and widening operationson the. remaining needles, all as usual in the prior art. In addition, I provide for the elevation of certain of the needles at the beginning of the knitting of the leg of the stocking in order to produce a welt of the structure shownin Figs. 2 and 3. Typically this structure is made by retiring, without drawing them below the verge of the needle cylinder, the odd-numbered alternate needles such as the needles employed to knit the wales 1, 3, 5, etc., in Fi 2. Knitting upon the other or even-numbered needles is continued for a number of courses, for instance, from .four to nine courses, the yarns emof the elevated needles upon the shanks of which the loops 1 the last course knit on all the needles, which maybe the first or one of the first few courses laid, are all retained.

After the intervening accumulation of sufli cient loops by the active needles, which are those of the even numbers 2, f1, 6, etc., of Fig. 2, the needles ofwales 1, 3, 5, 7 etc. are restored to operation whereupon the loops m, which they drew in the first course following their restoration, will be drawn through the loop y and will include the idle runs, or single wales w of the courses a, b, c, d and 6 made in the even numbered wales 2, 4, 6, etc. The structure resulting is therefore formed of clusters of stitches, a single Wale in width, projecting from the face of the fabric. Because of the manner of the formation of the loops a1 and 3 the wale containing these stitches is little elongated, and the welt is composed of a succession of bunches in the weltingwales 2, 4., 6, etc., separated by normal fabric in the wales 1, 3, 5, etc., which include as many yarns as there are stitches in the bunches.

It will be noticed that the fabric knit in the wales 2, 4', 6, etc. is formed of stitches facing in the same direction as the remainder or body of the fabric, and that the effect of the first and bending the outwardly complete circle of idly in front facing Q bunches or clusters shown.
