To all whom t't may concern:I

Be it'known that l, HARRY SWINGLEHURST, a citizen of the United States, residing in Philadelphia, Pennsylvania, have -invented \certain Improvements in Knitted Fabrics and in the Mode of Making Same, of which the following is a sprcication.

The object of my invention is to prevent the running back of stitches cast from the needles of a knitting machine in changing the character of the knitting, for instance in changing from plain web to ribbed web, by casting the stitches from certain cylinder needles, retiring the same and introducing dial needles in their stead, or inchanging from ribbed web to plain web by casting stitches from the dial n eedles, 'retiring the same and introducing cylinder needles in their stead.

4The change from ribbed web to plain web may be effected at the junction of the top 'and leg, or at the junction of the leg and foot of a stocking, andthe change from plain web to ribbed web may be effected after ,the

completion of a toe pocket upon a stocking tube, in which case the casting off of the stitches from certain cylinder needles may be followed immediately by the introduction oi corresponding ribbing needles for the formation of a setting-up course for ,the next sectionof ribbed web, or for the formation o the welt thereon, or any desired number of courses of plain web may be formed upon the remaining active cylinder needles be- 4fore beginning said setting-up course. v In either case a transfer operation is avoided and the production of the sock 6r stocking is therefore simplified and cheapened.

nIn the accompanying drawings Figure l, shows an exaggerated view of a piece of knitted web embodying my invention, when the change 'n the character of the knitting is from plain web to rilibed web; Fig. 2, is a similar view taken from the opp'osite side of the web; Fig. 3, is a sectional View of said web on a reduced scale, the section being taken through a standing Wale; Fig. Il, is a similar view showing aweb formed with a welt at the beginning of the ribbed section ofthe fabric; Figs. 5 and 6, are views similar to Figs. 1 and 2, respectively, but illustrating a fabric in which the change in the character of the knitting is from ribbed web to plain web;

Figs.A

7, 8, `9 and 10, are views similar to -Fig. 1, but illustrating otherways of effecting the object of my invention, when the change in the character of the knitting is from plain web to ribbed web; and Figs. 11, 12, 13 and-14, are'views, similar 'to Figs. 7, 8,

9 and 10, respectively, but showing a change from one having cylinder needles and dial needles, and that the plain web is being produced upon the cylinder nee- Specication of Letters Patent.

tion oi the same into elongated sinker wales intervening between the standing wales, sothat there will be, at the point of junction .between the plain and ribbed webs, a plain fabric of very open mesh, and of indefi nitel extent. -Such a method of changing from plain Web to ribbed web or from ribbed web to plain web is therefore, commercially impracticable, and in order to overcome the objection noted, I, inaccordance with one method of carrying out my invention, discontinue the formation of stitches on the standing Wale needles, while continuing such formation on the ncedleswhich are to be retired, this operation continuing for one or more courses, and preferably for a plurality of courses, before casting the. stitches from and retiring said needles, the resultbeing that the standing wales take the strain exerted upon the fabric, th'e discontinued wales being relieved from such strain and the running back 'of the stitches oisuch discontinued wales being thereby prevented. l i l I n Figs. land 2, ofthe drawing, a represent standing 4Wales of plain fabric which are continued up into the ribbed fabric and correspondingly lettered therein, b

ND LOUIS D. WILLIAMS, OF OGONTZ, PENN- representing discontinued wales of plain fabric, d rib wales which take the place of the latter, and j' sinkei" wales passing from one discontinued Wale b to another, the terni sinlier Wale. in this connection meaning the yarn between the needle wales.

In Figs. 1, 2 and 3, of the drawing, I hajve shown my invention as applied to a web in which the change is made directly from continuous plain web to ribbed web, and in Fig. 4, I have shown an instance in which, after'casting off the stitches of the discontinued wales b, a number of courses of plain web'g are rst knitted upon the remaining cylinder'needles, and a welt h is then formed in the usual way, before beginning the produc tion of ribbed web d: 'l

Figs. 5 ,and 6, show a fabric in which the change has been effected. from ribbed web to plain web, a representing standing wales contained in both webs, d discontinued rib wales, b plain wales which take the place of said discontinued rib wales and f sinker wales connecting the latter. y

in the fabric shown in Figs. 1, 2, 5 and 6,'the knitroo ting 4operation is arrested simultaneously upon all oi the standing Wale needles of the cylinder and the teri standing Wales a and a3, and, after the formation of lso course 5 on the needles which produce standing Wales a, a2 and a, the terminal stitchesof the discontinued wales b and b3 being in course 4, and the terminal stitches of discontinued Wales b2 and b4 being in course 7.

In the fabric shown in Fig. 8, knitting is discontinued upon the standing Wale needles after the production of course 3 in Wales a/ and a3, and after the productionof course 4 in Wales a"2 and a4, but is discontinued for but one course o n each needle, the yarn which forms the stitches in course 4 in discontinued Wales b and b3 failing to form stitches in the standing Wales a. and a3, the yarn Which forms the terminal stitches in course l5 in the said Wales b and b3 also forming stitches in the standing Wales'a and a3, and the yarn Which forms the terminal stitches in course 5 in the discontinued wales b2 and. b4 failing to form stitches in the standing Wales a2 and a4.

In all of the fabricsk thus far illustrated there are a plurality of yarns in some of the courses of the standing Wales corresponding to courses in the terminal portions of the discontinued Wales, because of the arrest of the knitting operation for one or more courses upon the standing Wale .needles While the knitting yarn is still istr being fed thereto as Well as to the alternating active needles, but the object of my invention may be attained Without recourse to this method of knitting orto the production of/a fabric of this character. In.

ric, as in ali of the preceding fabrics, the Inumber of courses of stitches in the terminal portions of the discontinued wales and in the initial portions ofl the rib Wales which supplant the same, together exceed the number of courses of stitches in the corresponding portions of the standing wales.`

In the production of the fabric shown in Fig. l0, knitting .is not discontinued at any time upon the standing Wale needles but long or slack stitches are drawn Aupon the retirable cylinder needles in the terminal courses of the wales b formed thereon, and in the'courses preceding said terminal courses, as indicated at 4 and 5, or such longer stitches may be drawn in more vthan one of such preceding courses, the effect It Will be evident that any of the modifications shown in Figs. 7 to 10, is applicable as Well to a fabric in which change is effected from ribbed web to plain Web, and in Which the discontinued Wales are, therefore, rib wales instead of plain Web Wales. (See Figs.

My invention is applicable to ribbed fabric having but a limited number of wales o f plain Web side by side; for instance, itis applicable in changing from a Web knittedin three-and-one rib, or aWeb knitted in five-and-one rib to a Web knitted in one-and-one rib, as will be readily understood.

While my improved fabric can, and in most cases will, be knitted With'a single continuous yarn, I have, in Figs. l, 2, 5 and 6 of the drawing, shaded this yarn so as to indicate more clearly the three different wales, the unshaded stitches showing the standing Wales, the lined stitches showing the alternating Wales of the plain Web, and the cross-hatched stitches showing the rib Wales.

It should be understood that in the various views of the .drawing some of the stitches have, as' compared with thiiir relation in the actual fabric, been distorted or displaced for clearer illustration of lthe manner in which they are interknitted. p

By the Words terminal portion as applied herein to a discontinued Wale I mean the actual terminal stitch and the stitch or stitches preceding the same in such Wale, and thus distinguish from the terminal stitch alone.

I do not here claim a composite ribbed and plain fabric, in Which the change from ribbed 'Web to plain web has been effected by discontinuing rib Wales and n replacing them by Wales of plain web, as this specific embodiment of myi-nvention forms the subject of a separate application filed by me, of even date herewith, Serial No. 277,898 but I claim as my present invention and desire to secure by Letters Patent:
