To all whom it may concern:

Be it known that l, RAYMOND Frsi-Inn, a citizen of the United States residing in Philadelphia, in the county of Fhiladel hia and State of Pennsylvania, have invented certain new and useful improvements in Vertically- Striped Knit Fabrics, whereof the following is a specification, reference being had to the accompanying drawings.

My invention relates to knit fabrics of the type which are produced by knitting alternate courses of yarns differing in kind: i. e., in color or texture. Such fabrics are well known as two-tone or heather-tone mixtures. By reason of the alternation of the two yarns they are substantially indistinguishable to the eye.

The object of my invention is to produce a knitfabric which will place upon such a two-tone or heather-tone background, a vertical stripe of a solid color. While the fabric may be used for other purposes it is convenient for me to describe it as appl ed to knit hosiery, and it is so illustrated in the accompanying drawings.

Fig. l is a view of the face of my knit fabric.

Fig. If is a view of the back of my knit fabric.

Fig. lllll is a diagrammatic side view of hosiery comprising my knit fabric; and

FiglW isa diagrammatic cross sectional view of the same along, the line IV--l[V in Fig. lllli.

Referring to Fig. l, it will be noted that the fabric is knit of two kinds of yarn distinguished from each other by their color, and which, for the sake of convenience, Tl will speak of respectively as white and black. Alternate courses of the said fabric are knit from differing yarns: i. e., courses, a, 0,6, g and i are knit of the white yarn, while the intervening courses 6, a), f and it are knit of the black yarn.' lit will also be noted that .of the wales of knitting, those numbered

l

2, 5, 6, 7, 8, 9, 12 and 13 are formed by the ordinary interknitting of the loops of each course with the course succeeding, thus producing for the region of said wales, a twotone or heather-tone background; while the wales 3, a, 10 and 11 are produced by interknitting long loops of each white yarn course with the similar loops of the next succeeding white yarn course, thus interknitting only alternate courses while the black yarn floats unknit behind these long loops, as seen in Figs. 1 and ill.

To knit such a fabric, it'is only necessary to vary the ordinary knittingoperation by causing the needles upon which thelong white loops are formed to hold their loops and fail to' receive the black yarn.

By adopting the, plan of knitting which I have just explained, the background of the fabric is formed by the parts which are knit in the ordinary way comprising multiple-wale sections and, as a'rule, the majority of the wales, and by reason of the alternation of the yarns course by course in these sections, the two kinds of yarn are so intermixed, as to prevent the eye from readily pickingout and distinguishing them, thus producing the desired dominating twotone effect to which I have referred above. @n the other hand, the wales which carry the longer loops to alternating courses have the effect of one-tone vertical stripes contrasting strongly with the background an? are composed on the face of the fabric 0 the one kind of yarn only.

lit is to be understood that any desired combination of yarns differing in color, teX- ture or other manner may be employed,- black and white being merely cited by way of example,-and it is likewise to be understood that the background sections and stripe sections may be of diifering widths and proportions. But the heather-tone sections are multiple-Wale sections and the stripe sections are narrow as compared with said sections. But to secure the desired effact, the two kinds of yarn must alternate practically course by course, as otherwise the eye is able to distinguish between the two kinds of yarn which com ose the background sections, and the desire heather-tone sheet is not secured.

The effect of these stripes may be en hanced by slightly varying the tension of the different yarns. in this way, the floats of the black yarn may be drawn across behind the long loops of the white yarn with suflicient tension to purse together the wales formed therefrom,--thus causing the vertical stripes to protrude slightly above the face ofthe fabric, as shown in Fig. IV, where 15-45 represents the protruding vertical stripes, while 16-46 represents the sections of two-tone background. The striped effect which is thus secured is also illustrated All Ati

lldfl lllltl in Fig. III whereis represented long hosiery having the calf, ankle and top of the instep knit as I have described, the heather-tone background being shown at 1616 and the vertical stripbs 15-15 standing out in sharp contrast to said background.

Having thus described my invention, I claim:

1. A vertically striped knit fabric formed of two kinds of yarn alternating course by course, the loops of succeeding courses being interknit along certain sections each comprising a series of adjoining wales to form a two-tone background; the loops of the alternating courses of one kind of yarn being lengthened and interknit with each other along the remaining wales; and the alternating courses of the other kind of yarn being floated behind the long interknit loops which form the face of said Wales.

2. A vertically striped knit fabric formed of two kinds of yarn alternating course by course, the loops of succeeding courses being interknit along certain sections, each section comprising a relatively large number of adjoining wales to form a two-tone background, the loops of the alternating courses of one kind of yarn being lengthened and interknit with each other to form sections alternating with the first mentioned sections and said second mentioned sections consisting of a relatively small number of wales, and the alternating courses of the other kind of yarn being floated behind the long interknit loops which form the face of the wales of the second sections, whereby the latter define narrow stripes of one color contrasting with a two-tone background defined by the first sections.

3. A vertically striped knit fabric formed of two kinds of yarn alternating course by course, the loops of succeeding courses being interknit along certain multiple-Wale sections to form a two-tone background; the

loops of the alternating courses of one kind of yarn being lengthened and interknit with each other along the remaining wales with the other kind of yarn fioated behind them, the tension under which said latter yarn is knit being such as to purse together the wales formed by the long loops causing the vertical stripes thereby formed to protrude uponthe face of the fabric.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania. this sixteeth day of March, 1921.
