METHOD OF ERODUCING SCALLOPS IN KNITTED FABRICS,

Application filed December 29, 1926. Serial No. 157,636.

This invention relates to knitted fabrics and particularly to a method for producing scalloped or picoted effects on the plain or V folded edges of knitted articles. a

One'of the objects of my invention is to produce the scalloped or picoted edge effects in both the body and the edge of knitted. fabrics on a knitting machine and. at the same time knitting the body thereof without removing the material from the machine. "This produces a seamless knitted article. I Another object of the invention is to provide a method by which scalloped or picoted edges may be produced on knitted fabrics in an economical and improved manner.

Another object is to provide knitted fabrics with open tucked portions which, when folded along a transverse line of the open portions, will produce a scalloped or picoted suitable spaced wales along atransverse line of the fabric, and .the said line. v In practice, the method employed for pro- :ducing the scalloped or picoted edges is car- 31) ried on in a knitting machine having groups of short latch'needles wherein the long latch needles are thrown into cooperate withthe short latch needles to knit the body of the fabric andthe long latch needles are thrown out while the short latch needles make a plurality of stitches and then thrown in to make a single stitch which binds in the threads from the plurality of stitches, repeating the process until the desired number of long stitches have been formed, then throwing in the long latch needles to cooperate with the short latch needles to knit the balance of the material and then folding over the top of the hose through the rows of long stitches in order to present thev scalloped or picoted edge.

The drawings illustrate a stocking embodying my invention and the views therein are as follows Figure 1 is a view of a childs stocking, around the top of which scallops and open work have been formed according to my new method.

Figure 2'is a view, drawn to a greatly enlarged scale, illustrating a method of makfolding the fabric along ing the stitches to form the open work and produce ordinary knitting in the body scallops shown in the stocking in Figure 1,

Figure 3 shows the upper portion of a stocking having the scalloped top shown in Figure l but drawn to a' larger scale and having additional open work formed inthe body of the stocking, f

Figure 4 shows the stocking in Figure 3 with its top folded through the open work to form acuff. p V I In producin astocking such as shown in the drawing, the knitting machine is set up and the stocking knitted in the usual man ner with the exception that as many long latch needles are spaced around. the cylinder as scallopsor formations of open work are desired; The cams are set so that the long and short latch needles cooperate to of the fabric but, when it'is'desired to produce the stitch which forms the open work and scallops, the cams behind the long latch needles are lowered during two or more reciprocations so that the loopin the hook cannot ride over. the latch and consequently is not pulled through the .loops'on the needles. The operation of knitting machines, includneedles, iswell known in the art and requires no explanation here further than that requiredto explain the methodof making the stitch required to scalloped effects.

Referring now more particularly to Figure 2, in which all'the. threads are shown as nearly in the same plane as possible, asis customary in drawings of this character, the

. ing cam changes and the use of long latch produce the openwo'rk and I l wales 1, 2, 4 and 5 would be made by short latch needles needle.

The short latch needles will operate to form stitches during each reciprocation but,

and Wale ,3 by along latch at the start of the operation, the cam behind the long latch needle is lowered so that yarns 6, 7 8 and 9 are held in its hook until it moves upwardly to engage yarn 10 when the cam is raised and these yarns pass behind the latch in the usual manner. Its hook engages yarn l0 and moves downwardly, causing its latch to close and casting off yarns 6, 7, 8 and 9. The cam is again lowered during the next three reciprocations and yarns 11, 12 and 13 gathered in the hook with yarn 10. The cam is again raised during the next reciprocation and yarn 14 gathered in the hook and yarns 10, 11, 12 and 13 cast off. This cycle of operap the stitches, made by the long latch needle 7 tion is given repeated with yarns 15, 16, 17

and 18, after which the long latch needle is.

actuated to cooperate with the short latch needles and knit the body of the fabric.

In Figure 2, the yarns are shown in nearly the same plane and without'distortion, as is the custom in illustrating knitted work, but it is well known that in practice each loop is bound into the adjoining loop and that the yarn contracts to form aclose fabric. Hence, it will be readily understood that from yarns 10, 14 and18, will draw the 'Ho'wever, it is evident that reasonable va-' riation may be made in the relative numher of long and short latch needles, the number of stitches dropped, and the number of long stitches made, in order to produce different shapes and sizes of scallops and formations of open work.

Some stockings are provided with turned over tops or cuflsand it is sometimes dosi'rable to provide the cuffs with scallops at 'both'top and bottom. The method of prod'ucing scallops 19 and open work 20 at the bottom of the jcufl has already been described.

By referring to Figures 3 and 4, it will be noted that the formations of open work i 5 '21 are similar to the formations 20 except that there is a group of long stitches in either end'of the formation and a Very long stitch at the center.

In knitting the stocking illustrated, I

time the cam so that, at any desired point in the body of the stocking, the long latch needles will make three of the long stitches shown in Figure 2, then a stitch considerably longer, and then three more long stitches. The severe tension on the yarn forming the longest stitch tends to wrinkle the fabric alongside the centers of the formations of open work so that, when the cuff turned over as shown in Figure 4, scallops 22 are produced; j

After knitting, the stockings are washed andboarded in the usual manner and the scallops stretched into shape by hand so that a permanent scalloped edge of pleasing effect is produced.

While I have illustrated and described my invention, as applied to the manufacture of hosiery, it will be understood that my meth- 0d may be employed in producing scalloped edges and open work effects in any type of knitted fabrics and that the relative sizes and locations of the stitches employed may be varied to suit the requirements of the manufacturer, and hence I do not limit my self; to the illustration used but consider that I am at liberty to vary the method of manufacture within the scope of the appended claims. V a The invention is hereby claimed as follows: I

In testimony whereof I have signed my name to this specification.-
