2 Claims. (CLSB- 201) This invention relates to improvements knitted fabric, and has particular reference to a seamless knitted fabric such as set forth in my copending application, Serial No. 730,666, filed 5 June 14, 1934, the presentapplication being a division therefrom. `v l The primary object of this invention is the provision of a seamless tubularfabric which may be Vknitted upon a double feed type of rotary cylinder knitting machine-and wherein may be incorporated horizontal stripedl effects, selective reverseplating, and selective color within color striped or spotted patterning in corelation to the horizontal striping and reverse plating effects. v Y

A further object of this invention isthe provision of an improved ubular knitted seamless l fabric which may embody selective reverse plating, horizontal striping, and patterned striping and designing upon a machine s uch as set forth inA my co-pending applications, Serial Nos.

730,666 and 662,354. l

Other objects vand advantages oi' thisinvention will be apparent during the course of the following detailed description. f l,

- In the accompanying drawings, forming apart of this specification, and wherein similar reference'Y characters designate corresponding partsY Vthroughout the several views,

Figure l is a side elevation of a stocking, showing in fragmentary detail the plating and selective .pattern wrapping which may be provided in the stocking in accordancewith my present invention, and as set forth in my parent application, Serial No. 730,666, of which the present applicationisadivision, l y YFigure 2 is a fragmentary inside view of a section ofthe stocking shown in Figure 1 on an enlarged scale, and showing. more particularly 4the plating and wrapping yarns, and the float portions of thelatter. A n

Figure 3' is an enlarged section of the-fabric of 'Figures I and 2, showing the face thereof and the stitches of. the various yarns forming the body,

. plating, reverse plating, and complementary selective needle wrapped patterning yarns.

Irl-the drawings. wherein for the purpose of illustration .is shown only one of a large variety of patterns which may be embodied in seamless tubular knitted iabricsaccording to my -present n invention, the

such fabric. Generaly letter P may generally designate Vthe machine upon which the 1mproved patterned fabric may be knitted comprises a double feed of both body and plating yarns so as to produce two knitted courses of the fabric for each revolution of the cylinder. horizontal striped effects may be produced by y changing the body and plating yarns in accord- 00 ance with the teaching setforth in my co-pending patterned v In addition, l

in application, Serial No. 662,354. The machine also embodies wrapping yarn feeds for each main yarn feed of themachin'e, and these wrapping vyarn feeds mayeach be capable of producing in the knitted fabric a color within color striping .or design spotting effect. The plating and wrapping feeds are of course selective' so far as needle and `course regulation are concerned.

Referring to the fabric P, as shown in the drawings, the rsame represents a seamless knitted stocking although the features of the invention are ynot to berconstrued as limited solely to a stocking. In general the design includes re- Yversely plated diamond shaped areas 500, the stitches of Awhich are stepped from course to course to provide in width and eighty courses in length. Of course the reversely plated patterns may vary as to shape and size. Y

Inasmuch as byreference to my parent application, Serial No. 730,666, it will be seen that the fabric is knitted upon a double feed type of machine, yseparate pairs of knitting yarns are used in the plated areas for adjacent courses. Thus, knitting yarns 8l and 83, which may be appropriately designated as respectively, are used to knit stitches in the fabric in one course, and in the adjacent course gray and black yarns 93 and 84% respectively knit stitches therein. Of course the two courses wherein the plating is effected from the yarns 8l-83 and 93-94 are produced during the same revolution of the cylinder of the knitting machine upon which the seamless fabric is produced. The reverse plating in the patterned area will be identical for the pairs Vof courses thus knitted during any single revolution of the cylinder, as Y will be seen by reference to Figure 3 of the drawings. l n

As will be seen' from Figure 3 of the drawings that the reverse plated pattern is stepped one Wale at each two courses. Knitting proceeds in the reverse plated'pattern starting at the top of the diamond at 5,02, as shown inA Figure l and proceeds according to the pattern lug lay-out on the patterning 'drum of the machine, as set forth in ymy above identified co-pending parent application, of which the present application is a division.

It'will of course reverse plated designs may be provided upon the fabric knitted upon the machine of my parent application. 1

Referring to the needle Wrapping yarns and their control so far as the seamless fabric is concerned with rrespect to lthe plated, areas, the needle wrapping yarns are controlled upon theY Vmachine as set forth in my co-pending application. They may betypically identified in the present example as red and yellow yarns. The

be understoodthaty many varied l gray and black yarnsA 2@ i plated diamonds.

yellow yarns are diagonally knitted to provide wrap stripe diamonds, the diagonal 'stripes oi' these yellow yarns crossing each other to provide the small wrap stripe diamonds in a cooperative patterned effect with respect to the reversely Ihe red yarns are spotted in the centers of the diamonds produced by the yellow diagonal striping yarns. This produces the so-called color Within color effect of needle wrapped yarns.

The striping is produced upon needles which are selectively controlled in cooperative relation with a control feed of the striping yarns thereto. In the double feed machine upon which the fabric is produced there is a double feed of needle wrapped yarns and at each wrap yarn feed the threads may be regulated in the manner set Yforth in my co-pending applicationsv Serial Nos. 662,354 and 591,689. Y

'Ihe red spotting yarns are fed toa selected arrangement of needles. Thus the spotting yarns indicated at Gill)a in Figure 2 of the drawings may produce knitted stitches 600 in the fabric. By means of pattern manipulation of the Vfeed fingers and needles,'as has been set forth .in my cof-pendingfapplicationsabove.referred to, other red spottedareas 60| may b e provided in other striped diamond areas at different courses than those courses in which the stitches B appear, as is clearly indicated in the drawings. Inasmuch as two courses of the fabric are knitted v for each revolution of the cylinder in the double feed type of machine whereon the fabric is knitted, such as set forth in my said cc-pending application, Serial No. 730,666, it will be understood that the red striping yarns fed to the needles as directed by yarn fingers and cams at one feed of the machine will appear-only in alternate courses, as is clearly designated in Figure 3.

Since at eachV feed of the machine the yellow K striping yarns are directed to the elevated and selected needles they appear in adjacent courses of the fabric to complete the bordering or other desired wrap-stripe pattern design.v This enables each yellow striping or patterning yarns to appear in each course of the fabric.

VOne of the striping yarns may be fed to a selected arrangement ofneedles to produce the stitches 628 shown in the fabric in Figure 3 of the drawings, and another of the yellow patterning yarns may be fed by its patterning means to other selected arrangements of needles in order to produce patterning stitches 84|?, as shown Vin Figure 3 of 'the drawings. These stitches 628 and Si@ are of course in complementary relation to complete the diamond-shaped pattern design, and the portions of these respective yellow yarns may be oated both Walewise and coursewise at the inside of the fabric, wherever desired. By

this arrangement in utilizing several different lap or needle wrapped yar`ns for each design, more complicated pattern designs may be provided than was previously possible, and it is not so necessary to oat the wrapping yarns coursewise across the width of the design; thus eliminating many oat threads which would ordinarily occur in wrap pattern designs, where the wrapping yarns are floated between widely spaced stitches in the same or adjacent courses. It should thus be noted that in the seamless tubular fabric each Y yellow patterning or wrap stripe yarn may be produced in adjacentcourses ofthe fabric and floated at the inside of the fabric wherever de- 5 sired notwithstanding that I knit the fabric upon a double feed machine. However. these adjacent courses of the web of the fabric are formed of different plating or body yarns.

The inside of the fabric P shown in Figure 2 has `shown thereon the'fioatportions 600* of the y red patterning yarns, and the small noat portions ofthe yellow striping yarns from course to course, etc.

Itwill of ,course be realized thatmany diiferent reverse' plated patterns and striping and pat I terned effects of the needle wrapping yarns may be produced in the fabric, as may be desired.`

From the foregoing it will be seen that Va seamlesstubular fabric has been provided wherein the body web of the article is formed of a plurality` ofplating yarns controlled so as to provide plated design areas, such as by reverse plating; the

plating yarns in non-adjacent courses being the same and the remaining courses being formed of other plating yarns. In this relationa selected arrangement of striping yarns Yare wrap striped.
