Cyclopedia of textile work : a general reference library on cotton, woolen and worsted yarn manufacture, weaving, designing, chemistry and dyeing, finishing, knitting, and allied subjects . , bears against a pin 182 projecting from thearm, and tends to hold the arm and lever in the position shown inFig. 150, a stop 183, projecting from ring 76, serving to limit the move-ment of this lever and arm toward the left. The circular plate 95, which rises and falls to control the actionof cams 90 and 97, is secured to a rod 184, which slides verticallythrough an opening in the cup-shaped bearing 4 (Fig. 154), and in aguide 185 carried by one of the bars 77. The lower end of slide-rod184 rests on upper end of arm 177, and, as the latter oscillates, passesfrom step 178 to step 180 over the incline 179 (Fig. 150) or vice action of these parts is so timed that the circular plate is elevatedto render inactive the needles having the long heels simultaneouslywith the first elevation of the lift-rod by cam 173, which causes thechange of yarn and the commencement of operation of the picker-finger ; but when the lift-rod is given its second elevation or hitch by 268 KNITTING 251. means of cam-lug 175, the step 178 simply moves slightly across thelower end of the slide-rod without affecting the elevation of the cir-cular plate. The disc carries also two segments 186, each having acam-surface 187 at one end to act upon a block 188 carried by a lever 189 pivoted at 190 to the frame ofthe machine and having a lug 191adapted to bear against the loweredge of the web-guide 75 when thelatter is to be lifted to elevate theneedle-cylinder. In order to adjustthe amount of elevation that maybe imparted to the web-holder andneedle-cylinder by the cams, theblock 188 is adjustably connectedwith the lever 189. The needle-cylinder rests uponthe shoulder 74 of the web-guide75 (see Fig. 154). The upper end of the latter is surrounded by theneedle-cylinder, and the cylinder can be rot
