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 . rder to pro-duce the diamond-points, the guard-blades 10 are employed, whichare swung toward the fashioning points 2, and press against some ofthese points, preventing them from engaging with the correspondingneedles and the picking of the loops from such needles in the operationof footing. The movement of the guards 10 into and out of contactposition with the fashioning points 2, is effected automatically duringthe operation of the machine by means of levers 11 and connectedmechanism as follows: The lever 11 is pivoted at one end to a shaft 12, and is provided 286 KNITTING 269 intermediate of its length with a roller 13, which bears normally uponthe concentric periphery 14 of a disc fixed to the rotary shaft 15, uponwhich the lever is thus supported without movement; but when theshaft 15 is moved longitudinally during the narrowing operation, thebearing of roller 13 is transferred from the concgntric disc to an eccen-tric periphery 16, which raises the pivoted lever IL Pivotally con-. Fig. 181. Draw-Cam Shaft, Bearing, and Brake. nected to the free end of the lever IL is a rod 17, the upper end 18 ofwhich is engaged so as to slide in a sleeve 20, which in turn is pivotallyconnected at 21 to an arm 22 fixed to the shaft 8. The free movementof the rod-end 18 in said sleeve is limited by a shoulder or stop 19,which comes in contact with said sleeve before the lever 11 is fullyraised, and raises it, so as to turn the shaft 6 and swing the guards 10outward, as indicated by the dotted lines. Figo 180 illustrates a very important improvement, which allows 287 270 KNITTING of a micrometer adjustment of the needle-bars. It is very importantthat the needles should always be in exact co-operating position withthe sinkers; and it will readily be understood by referring to theillustration, t
