Fig. 3. Spindle Drive Showing Pulleys and Bands. the end of the frame is a jackshaft on which, outside the end frameand close beside the belt pulley, is a pinion gear meshing into awheel gear that drives, on its shaft inside the frame, an unusualarrangement of gears — double gears — so arranged that the teethon one pair are just half the distance of one tooth ahead of theother pair. Such an arrangement serves to materially lessen theback-lash that must inevitably occur were but one pair of gearsonly employed. This system of gearing transmits motion to theInart cam shaft that gives the rise and fall to the building motion.The reversing at each end of the stroke is attended in similar 16 KNITTING. mechanisms with more or less back-lash which in this machine iscontrolled by this double gear arrangement.

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
