F is fastened to the shaft O, which is given anoscillating motion in a manner easily understood from Fig. 69. To therod O, which carries the feeler, not shown in Fig. 69, is fastened thecasting S^ pivoted at S- to a forked lever S-. The fork of S- fits about 96 COTTON YARN MANUFACTURE a pin S** on the gear S^. S^ gets its revolution from the roller S^ revolves, the fork S receives an oscillating motion which iscommunicated to O, the inertia of the feelers and their attachments beingsufficient to prevent the knuckle joint at S- from bending. The lowerpart of S^ can be seen to be formed into a finger which rests against the. Fig. 69. projection T^ on the weighted lever T. The upward extending projectionT- of the weighted lever engages as shown in Fig. 68, with a catch onthe casting T-\ T may slide along on the rod S, being fitted looselytherein. It is also penetrated b}^ the shaft O. (The same letters representthe same parts in each drawing.) The casting V is screwed to the shipperrod S by the set screws a a and has a forked end fitted around the DRAWING 97 shaft O. Whenever S moves, V ma}^ move along O. Further along therod S is the belt fork S ^ ^ which is used to move the belt from the fast tothe loose pulley or vice versa, to stop or start the machine. Suitablyattached to the slipper rod is the handle H shown in Fig. 63. Contin-ually pulling against the casting T^ is the spiral spring attached at theopposite end to a bracket bolted to the machine frame. When the machineis running, the parts occupy the position shown in Fig. 68. The belt ison t
