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 . s during a portion of its shield is secured to the bracket with a bolt to adjust the amount offeed imparted to the pattern-chain. A ratchet 43 (see Figs. 163 and164) is secured to the shaft 30 on the opposite side of the pulley 34;and this cam-driving ratchet is intermittently rotated by means of apawl 44 when permitted by the lugs of the chain. The pawl 44 is alsoconnected with the elbow-lever 25, and is reciprocated thereby. Theshield is pivoted on a pin 46, carried by the bracket and extending 255 238 KNITTING over both ratchets and chain-pulley, and is provided with an arm 47,having a pin 48, which projects into the path of movement of the chain-lugs. A spring 49 is coiled about the pin 46, and tends to hold thearm and shield in position; but when a chain lug raises the pin, theshield is depressed, the pawl engages a tooth of the ratchet, advancesthe latter, and partially rotates the shaft and the cam-discs. One complete rotation of the shaft 30 and its cams takes place.

The knitting opera-tion itself continues uninterruptedly without regard to the rotation ofshaft and cams; but when a stocking is finished, the rotation of theshaft effects the automatic stoppage of the entire knitting operation;and, during the single rotation of the shaft, it also effects two tempo-rary shafts of the driving-belt, to slow down or ease off the machinewhen the clutch-hub is moved into engagement with the pinion movement of the hub changes the knitting from circular or round-and-round work to the narrowing or widening at heel or toe, one-half 256 KNITTING 239 of the needles being throw
