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 . The heart cam Fig. 6 has a long and short side, imparting tothe building rail a slow rising movement, making a close wind onthe bobbin and a quick falling movement which lays the yarn 16 KNITTING. across the close wind and binds it in a manner best adapted foruse on a knitting frame. The building rail, see Fig. 4, is con-nected with the heart cam in the following manner: By actionof the cam, a lever on a rockshaft parallel to the cam shaft, witha cam roll near the vibrating end is made to transmit its motionby means of a chain belt attached to the above lever and runningover an idler wheel to connect it with another rockshaft leverat right angles with the cam shaft. On this rockshaft another. Fig. 5. End View of Cone Winder. lever, connected by upright rods to the building rail, gives to it arise and fall corresponding to the height of the cone-shaped of the winder bobbin. On a third lever of this rockshaft is aball weight to equalize the motion, balance the weight of the cuprail or building rail, and thereby relieve the heart cam of exces-sive wear when lifting the rail. The upright rods to the building 17 10 KNITTING. rail are near eacli end of the lail; the rockshaft with lifting rodlever and ball counterweight is consequently duplicated at theopposite end of the machine, the rockshaft being connected withrod and levers. The upright rods are not connected to the levers,but, having a broad heel, ride easily on a small roller wheel in theends of the levers. This arrangement permits a free sweep of thelevers with a minimum of friction. >
