The Needle-Cylinder. The needle-cylinder 72 extends through acentral opening in the cam-ring (see Fig. 154), and rests upon an an-nular shoulder 74 formed upon web-guide 75. The upper end of the 258 KNITTING 241 web-guide extends within the needle-cylinder; and the lower end issteadied within ring 76, supported by two rods or bars 77, which de-pend from the bottom of the cup-shaped bearing 4. The ring 76 has aprojecting lug 78 (see Figs. 149 and 150), to which block 79 is securedby means of a bolt. A stop 81 extends vertically through the inner endof the block and projects above It. The web-guide 75 rests on thestop, except when raised for lengthening the stitch; and it supports theneedle-cylinder by means of the shoulder 74. The stop being ad-justable in the block 79, the needle-cylinder may be adjusted to alterthe length of Fig. 152. The Knitting Cams, A cam-web 82 which forms about three-fourths of a circle (see Figs. 152, 153, 154, 157, and 158), is formed ateach end with an incline or cam 83, and is secured to thie ring 70. Thecams 83 act on the heels of the needles to raise them during the knittingoperation, the heels riding on the top of the web after being raised un-til acted on by one of the draw-cams. During straight or round-and-round knitting, but one of the cams 83 acts; but on heel-and-toe work,when the cams are all given a rotary reciprocating movement, the twoinclines or cams 83 act alternately to raise the needles. The two draw-cams 84, to lower the needles and draw the loops of yarn, face in op-posite directions^ toward each other. Each cam 84 is formed on the 259 242 KNITTING end of a block 85, which
