. As the looper is withdrawn or recedes, the yarn is carried with it, and the loop is formed in connection with the cylinder needles, the yarn being alternately engaged with the looper hooks and cylinder needle and held until same has passed the body wales or web- .forming point. Opposed to the brush 24, and

carried removably upon the periphery of the disk 11, is the looper retainer 25, the urpose of which is to prevent any upwa r movement of the loopers as they are projected to engage the yarn and return with the same.

A t 'ter the 'web' has been formed, and to properly feed the same within the cylinder and not injure or-break the web, as is customary with-the stress devices now used, I

i v employ the'rotary depressor or'feedcr 26, which is journaled upon'the angular frame 27, carried upon the periphery of the disk 11; the wheel being disposed at such an angle as to have its peripheral edge enter the spacebetween the dis: and cylinder far.

enough to press the finished web below the needles. The web-pressing wheel or disk 26 is pivotedin oblique fixed bearings at the extreme recession point of the.cylinder-and dial needles, and therefore retains this relative position at all times.

:In Figs. 5 and 6, the loopers 28, are mounted in the same vertical line, as the needles 29, the loopers being below andof course having their shanks 250, in the same radial line, but nearer the center than the shanks 31 of the needles;

From the foregoing description, taken in connection with the drawings, the operation of my machine is readily understood, but briefly stated, it is as follows 1tefcrring to Fig. 1'- and to the left hand side thereof, the cylinder needles have and retain theweb yarn a, and are gradually rising as at b to insure the latches falling, but not 'hig'hfenough to cause the yarn a,- tdfa'll below the latches. Theloopers as the pass theyarn guide, hook the yarn c an as the cylinder needles pass this point,

the catch the yarn 0, the loopers receding to,- orm the "loop while the cylinder needles a's'sist them' byoldin'g 'the yarn; As the dial tnd cylinder revolve toward the right, the yarns (Land 0 are carried by theneedles and the loopers, the cylinder needles as they approach the yarn d, at e, being projected higher than at b, the yarns a and a slide down below the latches, so that after the cylinder presser wheel 26, the yarn 4, still remaining in the cylinder and dial needles.

In Fig.4, I have illustrated the operation ofthe needles and loopers,- with the looper yarn in diagram. From this it will be clearly seen that the loops 7, are formed and secured in the Web; the loopers for form ing the loops, at all times, operating below and within the needles of both thecylinder and dial, and upon the receding; or pull stroke of the loopers. WVhat I claim, as new, is

the dial needles having moved 1. In a knitting machine, the combination ofa cylinder and a dial, needles carried. by the cylinder and dial, loopers'carried'by the dial, said dial, having radial grooves .to

receive a needle and a looper inone and the same groove so as to permit said needle and looper to slide longitudinally in the groove and means for operatin loopers independently 0 each other, said loopers operating to engage the looping yarn from below and within the needles to form loops upon the pull stroke.

2. In a knitting machine, thecombination of a'cylinder, needles mounted therein a cam to operate said needles, a dial provided with radial grooves fitted to receive and permit a needle and looper to slid'e longitudi nally in each groove, a cam for operating the needles and a cam for operating the .loopers, said loopers operating to engage the looping yarn from below and. within the needles to form loops upon the pull stroke.
