spaced by plain areas.

A further variation may be produced by providing, e. g., a red body yarn and a black pile yarn at alternate feeds, while leaving a black body yarn and a red pile yarn at the intermediate feeds. Now if cam I9 is advanced at one of two adjacent feeds and cam 20 at the other, the sink ers B will cause red pile loops to appear at the corresponding wales at one feed and the sinkers A will cause black pile loops to appear at the remaining wales, thus making a vertically striped fabric. By reversing the relation of the cams, red loops will be made to appear at wales A at the first-named feed and black pile loops at the second-named feed at wales B, thus producing a broken or checked design. If both cams are advanced at all the alternate feeds while the cams of intermediate feeds are retracted, horizontal red stripes will appear, while if both cams are advanced at all the intermediate feeds while at the alternate feeds both cams are retracted, horizontal black stripes will appear.

It will thus be seen that I have made provision for making a wide variety of designs by the use of pile loops, and for changing with ease from one design to another by changing the location of studs 26 and by providing such studs at positions indicated or leaving the same. blank, and further by altering the pattern control of the ratchet driving means.

It will be obvious to those skilled in the art that many variations may be made in the devices shown in the drawings and described in the specification, all without departing from the spirit of the invention; therefore I do not limit myself to the means so shown and described but only as indicated in the accompanying claim and as necessitated by the state of the art. For instance, while I have shown two levels of shoulders on the sinkers, it is obviously within the scope of my invention to provide additional levels, with appropriately located actuating cams and corresponding abutments on the wheel, etc.

Having thus fully described my invention, what I claim is:

In a machine for knitting patterned pile fabric, the combination of a needle cylinder, a circular series of needles therein, a plurality of series of sinkers cooperating with said needles, said sinkers having web-holding fingers and the sinkers of each series also having sinker-advancing shoulders at an individual level, means for feed-' ing a main yarn and a pile yarn in such relation to said sinkers as to form pile loops over said fingers on fully advanced sinkers, cams each positioned to engage with the advancing shoulders at one of said levels, a wheel in a fixed parallel relation to the axis of said cylinder, removable studs on the periphery of said wheel at levels corresponding to those of said cams, and pattern-cone trolled means for rotating said wheel, whereby changes in patterns may be effected automatically.
