' KNITTED FABRIC.

Original application filed January 15, 1920, Serial No. 351,701. Divided and this application filed September 23, 1921.

Montgomery and State of Pennsylvania,

have invented certain new and useful Improvements in Knitted Fabrics, of which the following is a specification, said specification being a division of an application filed by me Jan. 15., 1920, Serial No. 351,701.

. The invention relates to a new fabric. The fabric is produced on a circular rib multiple feeds. Changes are made in the stitch, say from plain to tuck, and from tuck to plain, and

' these changes are made to advance in position around the fabric in one direction at one feed as the courses are knit at this feed, whereas at another feed, and consequently in different courses, the said changes are made to lag and thus these changes take place spirally around the fabric, one change making the spiral advance in certain courses from wale to wale or groups of wales, while the other changes make the spiral lag' in the other courses and from wale to wale or groups of wales.

The drawing in Figure 1 represents a face view of the fabric. I

Fig. 2 is a key for reading the drawing of Flg. 1.

This fabric is produced by a machine and method describedv in my Patent No. 1,406,253, granted February 14th, 1922.

In Fig. 1, and according to the key of Fig. 2, the portions a indicated by crossing broken lines running in opposite directions, represent plain fabric; the portions 1), I), made up of full dark lines crossed by lighter broken lines represent tuck and plain parts of the fabric, intermingled in any desired order, and the parts marked 0 made up of heavycrossing lines represent the formation where the tuck contained stripe I) running spirally around the fabric in one direction crosses or inte'rmingles with the tuck contained stripe 6 running around the fabric in the opposite direction.

The zig -zag appearance of each diagonal stripe is due to -the distortion resulting from the two different kinds ofstitches emcontaining diagonal or spiral stripes whichployed, namely, tuck and plain. It will be understood that the structure of the fabric resultsfrom the alternating plain and tuck Serial No. 502,678.

run in one direction crossing the alternat- I here are of plain fabric. At 5 the courses" are made up of mixed plain and tuck course lengths, and at 0 the formation results from gheb crossing of the tuck containing stripes The fabric above described may be made by feeding in four yarns at different points around the needle circle. I

. At the first feed there will be mechanism as shown in my patent above referred to at C for inaugurating the making of short alternating course lengths of plain and tuck stitches, the successive changes taking place not at the same wale but at the successive wales around the fabric, so that these changes will lead in respect .to the wales and thus produce the spiral stripes running in one direction around the fabric.

At feed D (of the patent) a similar action will take place, but the changes here will lag and produce spiral stripes running 'in the opposite direction around the fabric.

At A and B (of the patent) there are plain feeds.

I do not limit myself to any particular number of feeds. Three feeds may be used.

I claim 2- 1. A knitted fabric having a plurality of separate yarn forming courses with tuck andfrib changes in the stitch, advancing in respect to the wales in one direction in the courses produced by one yarn, and lagging in respect to the wales in the successive respect to the Wales in one direction in the courses produced by one yarn and lagging in respect to the Wales in the successive courses produced by another yarn, the diagonal stripes thus produced crossing each other, said crossing in contour, substantlally as described.

3. A knitted fabric having a plurality of separate yarns forming courses with tuck and rib changes in the stitch, advancing in respect to the Wales in one direction in the courses produced by one yarn, and laggingin respect to the Wales in the successive stripes being zig-zagcourses produced by another yarn, the diagonal stripes thus produced crossing each other, said knitted fabric being seamless and tubular and the stripes being zig-zag in contour and forming diamond shaped figures contiguous throughout the surface, each diamond figure being bounded by the contiguous diamonds, substantially as described.

In testimony whereof, I afiix my signature.
