BIB-KNITTED) FABRIC AND METHOD OF THE SAME Application filed March 18, 1929. Serial No. 347,667.

Our said invention relates to a rib-knitted fabric and its object to provide ornamental features in connection with such a fabric. We have found that if two or more yarns are fed to needles of a rib knitting machine in plating relation, whereby one yarn appears at the outside of the fabric on both faces thereof, they may be so manipulated as 'to reverse their position and cause a yarn normally concealed wholly or in part to appear on the faces of the fabric. A similar method has heretofore been disclosed for plain fabrics in application Serial No. 30,102, filed May 13, 1925. A mechanism applicable to produce such plain fabric has been disclosed in application Serial No.'96,049, filed March '19, 1926, Reissue No. 17,705. In the applications mentioned the patterns are pro-' duced by flexing needles outwardly from their normal position in the needle bank, or in a forward direction, the side of the needle at which the latch of a latch needle is found being ordinarily considered the front side thereof. In this way horizontal and vertical stripes, checks and many other figures of the most diverse character can be made in a ribknitted fabric.

Referring to the drawings, which are made a part hereof and in which similar reference characters indicate similar parts:

Figure 1 is an elevation of a piece of rib fabric, showing designs made by the method herein described,

Figure 2, a transverse section on: an enlar ed scale, I I

igure 3, a detail elevation of a fragment of the fabric on an enlarged scale, 7

Figure 4, a fragmentary perspective, on an enlarged scale, illustrating the operation of the needles, and g 4 Figure 5, a diagram showing the positions of two yarns in successive dial and cylinder needles at different periods in their operation.

In the drawings reference character 10 indicates. generally what may be referred to as the normally-plated having reversely plated 11. It will be seen that the figures are separated by normal plating and include lengths part of the fabric, gures indicated at made of a white yarn 12 and a colored yarn 13. 1 Considering the fabric as made on a dial and cylinder machine it will be evident vthat in the dial loops a and g,aswell as in the cylinder loopsf and la -the colored yarn ,ap-- pears on both faces of the fabric while the white yarn is wholly or partially concealed by the colored yarn in these loops. In dial loops 0 and e, as also in cylinder loops 6 and d, the white yarn appears on the faces of the fabric, wholly or partially concealing the colored yarn in said loops. This gives rise to the novel and ornamental efiects above described. The condition is further illustrated in Figure 3 where the colored yarn'lies behind the white yarn in certain stitches, whereas the whiteam is behind the colored yarn in other stitc es. I

In Figures 4 and 5 we have illustrateddial needles '14 and cylinder needles a, b, 0, d, e, 7. These are the needles occuring iii a small segment of a circular rib-knitting machine this being the type of machine. in

which our process is preferably-carried on. According to the arrangement here'fillustrated for the course of stitches being formed the dial needles operate in an ordinary manner to knit loops of the yarns 12 and ,13, which are fed to all the needles in'plating relation, but selected cylinder needles are given a special movement by some such selective means as-that illustrated in application 96,049, above referred to, to cause them'to move outward at the knitting end. We have discovered that as a result of such selective dis placement of cylinder needles out of the normal needle circle both sets of needles may a forward needle which has just passed the instrumentalities whereby the needle is caused to move radially outward of the needle circle. It will be understood that the needles could be moved selectively inward away from the normal needle circle instead of outward with similar results. By appropriate selective control of the cylinder needles patterns such as that shown in Figure 1 ma be formed, or other patterns of almost infinite variety. In like manner needles of a straight knitting malzhine can be moved out of the needle row for reverse plating.

It will be obvious to thos' skilled in the art that many patterns can be made of the fabric described and that the fabric and the method of knitting may be varied also in other particulars and therefore we do not limit ourselves to what is shown in the drawings and .described in the specification, but only as indicated in the appended claims.

aving thus fully described our 'said invention, what we claimand desire to secure as Letters Patent is:

1. The process of effecting a change from normal to reverse plating in ribbed fabric formed on two coacting series of independent needles comprising operating such needles independently, and during the knitting operation while two yarns are being acted on thereby in plating relation, deflecting certain of the needles of one series at the thread-receiving end whereby a change from normal plating to reverse plating is caused to take place.

2. The process of effecting a change from normal to reverse plating in ribbed fabric formed on a circular series of independent cylinder needles and a circular series ofindependent dial needles comprising operating such needles independently, and during the knitting operation while two yarns are being acted on thereby in plating relation, deflectin certain of the cylinder needles at the thread-receiving end whereby a change from normal plating to reverse plating is caused to take place.

3. The process of effecting a change from normal to reverse plating in ribbed fabric formed on a circular series of independent cylinder needles and a circular series of independent dial needles comprising operating I .sfich needles independently, and during the knitting operation while two yarns are being acted on thereby in plating relation, deflecting certain of the cylinder needles. outwardly at the thread-receiving end whereby a change from normal plating to reverse plating is caused to take place.

a 4. The process of effecting a change from normal to reverse plating in ribbed fabric formed on two coacting series of needles comprising knitting ribbed fabric on such needles, and during the knitting operation while two yarns are being. acted on thereby in plating relation, deflecting certain of the needles of one series at the thread-receiving end whereby a change from normal plating to reverse plating is caused to take place.

5. The process of effecting a change from normalto reverse plating in ribbed fabric formed on two eoacting series of independent needles comprising operating such need es independently, and during the knitting operation While two yarns are being acted on thereby in plating relation, deflecting certain ofthe needles of one series at the threadreceiving end whereby a change from normal to reverse plating is caused to take place at both. faces of the fabric.

In testimony whereof we affix our signatures.
