In producing a stitch when using the method embodying the invention, a flat machine is used as shown in Figure 1 said flat machine being of the usual construction and provided with a racking lever 1 for racking the loops in a well known manner; The

front bed 2 carries a number of needles 3 which function during the formation of the stitch while the jacks 4 are permanently dis- 1927. Serial No. 188;?58.

carded. The rear plate. is provided with the usual number of needles 6, said needles functloning continually. As indicated in Figure 3, there is preferably every third jack 4 discarded though a greater or less number could be; discarded without departing from the spirit-- of the invention. After the jacksd have been discarded as shown in Figures '1 and 3, the machine is racked by'pushing downwardly on lever 1 and then the cam of themaclrinecaused totravel in one direction. Lever 1 is moved a second time and the parts movedback from the second stroke. After this has been done, the lever 1 is moved down to the third position and the cam again shifted to produce a row of loops. The lever 1 is then gradually moved backup to its former position and then this operation is repeated. The racking operation distorts the loopsso as to produce the wavy effect shown in Figures? and 8 and also produce the an rangement shown'in Figure 4;. This assists in producing the loose effect shown in Figures 7 and 8 when the knit goods has been completed. j I

Preferably eleven rowsof loops are formed and then all of the needles 8 are moved up manually by a plate or other instrument whereby upon'the nextactuation of the cam, said cam will merelypull the needles back to the position shown in Figure lwithout forming a new loop. The machine is then operated until eleven more rows ofloops are formed. and then this. action is repeated, namely. needles 3 are moved upwardly a sufficient distance to begout of theway of the cam except'tobe moved down toa position by the cam as the same passes. When the needles 3 are moved upwardly manually, they will pass up through the loops 7 for instance, shown in Figure 1 and then when the cam moves them downwardly again the needles will pass through these loops and allow the loopsco become free so that the needles will at this movement be without any loops. On the next actuation of the needles 3 they will engage the yarn and form loops in the usual manner and will continue to form loops which are interlocked with the loops of needies 6 until the needles 3 are again manually 'IDOVCCl upwardly. It will thus be seen that the needles 3 form loops which are discarded on each twelfth movement of the machine. As the machine operates, the fabric 8 is knit and in order to secure the desired results, a

'suitable weight 9 is connected with the fabric 8 for pulling the same. This weight will cause the discarded loops to unravel and in fact, the eleven former loops formed by the front needles 3 will be unravelled, thus presenting to the other loops substantially twice the amount of yarn for each loop and by reason of the fact that loops have been formed, a kinked or crimped appearance will be presented as well as a loose knit formation as shown in Figure 8. If the loose formation shown in Figure 8 was stretched until the parts were tight,it would appear substantially as shown in Figure 6 except the edge formation, which formation is formed by using all of the needles on both sides of the machine.

From Figures 9 and 10 it will be noted how immediately after the loop 7 has been discarded, the needles 3 will form loops through the next adjacent loops of the needles 6 so that the knitting operation is continued with front and rear looped formations, the front looped formation being later unravellecl and allowed to move into the rear loops to produce the effect shown in Figure 8 which simulates the usual hand knitting now in vogue. In case the weight 9 is not used, the front loops will not become unravelled as there is no strain tosecure this result. In a case of this kind it will be necessary to stretch the fabric manually and thereby pull out the loops-formed by the front needles in order that the efiect shown in Figure 8 may be secured. As the unravelling of the front loops is produced by temporarily discarding needles 3 every twelfth run or some other run, it will be evident that all or any part of the body of a knit piece of goods may have the loose formation shown in Figure 8. If desired, part of the garment may have this loose formation and part the usual knit formation with loops on both sides of the needles remaining in the fabric. Also, by not throwing out the needles at the edges of the garment as shown in Figure 7 comparatively tightly knit edge sections are presented which will not un 'avel while a loose central body is presented. This will, under certain circumstances, present a pleasing piece of knit goods and also present a good foundatioirfor stitchin when the goods is connected together to form a builtup or manufactured garment, as

for instance, a sweater. Y

What I claim is:

1. ihe method of forming a stitch comprising the use of a flat knitting machine for knitting a piece of fabric, discarding permanently certain needles on the front plate, continually racking the knitting machine during the knitting operation, knitting with the remaining needles in the usual manner for a series of rows, discarding one set of loops formed by the needles on the front plate, continuing the knitting operation in the usual manner, and finally pulling the knit fabric until all of the loops formed by the needles on the front plate are unravelled.

2. The method of forming a stitch in knit fabric comprising knitting a piece of fabric on a fiat machine, continually racking the knitting machine during the knitting operation, permanently discarding certain needles on one side of the machine, forming and discarding at spaced intervals a row of loops on the side of the machine having said discarded needles, and subjecting the fabric to a'weight acting longitudinally on the fabric until all of the loops are unravelled on the side where said loops have been discarded.

3. The method of forming a stitch in knit fabrics comprising knitting a piece of fabric on a flat knitting machine, continually racking the knitting machine during the knitting operation, discarding one row of loops on one side of the machine at certain intervals, and then stretching the finished fabric to cause all. the loops to unravel formed by the needles from the side of the machine having the row of discarded loops.
