Aclose Vpractically all or' at least the major portion' et the workingl parts except the The needle-cylinder N, see-Fig. 2, is tubular, its'periphery being provided with uni formly spaced longitudinal grooves for guidi ing the moyable' etch-needles 1 2 mounted' The; needle-cylindenas drawn, is pritY atthe top with a. fixed' inner rin member oz having radial grooves formed in "fits upper'and lower portions and. alternating with said yneedle-supporting grooves formed fin 'thc' cylinder. proper..

The sinker-carrying ring portion of the revoluble needle-cylinder is =s u rmounted by a recessed stationary cap- I Bearing G;.the latter being supported by said member n and held in the horizontal posi.-

The ringG, see Figs. 2 4 and 5,V is further provided with a suitably mounted normally stationary horizontal cam w, also located iii the path of the sinkers and at the usual knitting or stitch-forming portion. The construction and employment of the last-named cam is' novel: It extends through .the side of the cap-ring .and terminates in a bent arm lw2 arranged to form a space or opening of betweenit and the adjacent peripheralsuriace of the ring, the arrangement being such that a downwardly extendingidog or finger w1 fixed to the .under .side of the latch-ring member and |posi 'tioned in said opening maintains the-cam in .thenormal retracted or operative position to properlyactnate the sinkers in a successive. manner. v the'com lotion ofthe werk, the a'et of lifting the atcb-ring withdraws said fingen lw1 from the cam, a push-spring 0T at the simietime automatically advancing the latter inwaijdly to. -its limit thus temporarily and si'- multaneously moving the. corresponding sinkers thereon out of the normal-working Aosition, see-Figi. 7, all fthe sinkers then registering orlying in the circular path and being inoperative. ally means of this device the points of the transfer-ring readily position themselves. back of the respective needles when theI operator applies it to the cylinder preparatory .tn the topping oplipon stopping the machine, as at 85 i .iii
