platedrwork, e. knitting with two yarns of dif- 1 ferent color, weight or material and causingv one yarn fto 'appear on the inside of the fabric and the other on the outside, and if then certain needles are replaced by `othershaving their hooks.

set forward or outward from the series by a space, -e. g. 3%" or'l'", allother conditions being the same,fthenthe needles having the regular hooks will throw one yarn on the outside and those having their hooks set forward will throw the other yarn to the outside, making a fabric with Vertical plated stripes. A machine may be setup for plating by' using separate guides for the two yarns or a single guide with two-holes in it, the guide for the face yarn in any case being nearer the cylinder than the other yarn. Usually more tension is also required on the face yarn. When forward and backward sets-ofhooks are used the forward hooks will plate regularly and the backward hooks will plate reversely.

-I have found that by using uniform `needles and projecting the hooks of certain needles forward on one-round and others in succeeding rounds, all in predetermined order, patterns may be plated on the fabric such as checks, stripes and figures of various kinds.

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

Figure l shows a series of needles in elevation in the positions assumed in relation to a pair of yarns while passing a stitch cam,

Figure 2 is a plan View with the upper ends of the needles omitted for the sake of clearness,

Figure 3, a similar view showing the fabric in process of formation,

Figure 4, an elevation also showing the verge of the forming fabric, the needles in Figs. 1, 2, 3 and 4 all being in process of passing the stitch cam,

Figure 5, a View similar to Fig. 2, and

Figure 6, a view similar to Fig. 1 except that the needles have moved a little further with reference to the cam.

In the drawings a pair of yarn guides C and D are indicated as being formed on a single yarn nger E or other guiding instrumentality, the

(0160-30) i guide vC being nearer thecylinder than guide PATENT OFFICE D. A pair of yarns are shown as passing through guidesC and VDand said yarns are marked for convenience R. and W, the first being hereinafter described as a red yarn and the second as a White yarn. Itis of `course understood that the yarns fecting the invention.

may differ by other characteristics WithoutafV4 ',As a matter of further convenienceltending' to correct understanding of the invention they needles are numbered from 1 to 9 and are indicated as being divided into two series, each series consisting of groups of two needles and the groups i being set alternately forward and fbaok by anyv convenient means. The staggeredfarrangement will be vunderstood by examination of Figures 2` and 3 and the positions ofthe needles are further marked on vFigure 1 as needlesvforwardv and- It will` beseen that the series* including needles 3, 6; 1l are forward, i. e. assum-'f ing the machineto be a circular one they Vare in some way or another'forced radially'out fromthe cylinder as compared with needles 4',j5,'-8, ElY

which are in their normal position at this time,

As clearly indicated in Fig. 1 the red yarnis lowerv than* the white and remains soup to the positionof needle 1 which being forward has the redvyarn: atthe back whereby it will appear on the face of the fabric.A 'Needle 8, however, which has just knocked-over or cast-off its loop, this needle being at -its lowest point where it has drawn'Lv the new loop to its full extent, has the'red f'y'arn at the front whereby it will appear at the wrong side or back of the fabric and so has needle 9 which has passed the lowest point of the stitch cam. The different positions of the yarnv are further shown in Figures 2, 3 and 4.

Preferably the red yarn has tension on it, thisv the new stitches are being drawn down .throughy the old loop. If the hook is forwardthe yarn with the tension on it (the red yarn in this case) will be drawn to the front rof the hook as the needle approaches its lowest position and the other yarn will find a place back of it. The yarns Will, of course, remain in the same relative position as the stitches are drawn through the old loops, the yarn that is at the front of the hook showing on the back of the fabric and the other on the face of the fabric. Briefly stated the yarn with greater tension goes to the outside or face of the fabric when knit with forward hooks and to the inside or back of the fabric when knit with backward or set-back hooks.

In Figures and 6` the series of 'needles has moved forward withlreference-to the stitch camto such an extent that the forward needle 6 is at its lowest point of movement (knocking-over point) while needle 1 has passed the lowpointofthe cam. As the forward needles'reachY the positions indicated in these ffguresg.,thefredv yarn assumes the rear position and tliefwhite-is at the front, i. e. the red yarn will appear-attlieface of the fabric and the white at'the back;

It will be understood from the foregoing that with the needles arranged and. manipula-ted;l as:
