is near but not toughing iadd touching iaddend actuator 22 which is pivotally mounted on shaft 21 as shown the left end of actuator 22 is closely positioned above solenoid 18 so that only a slight air gap 23 is found between the top of the magnetic core member 20 and the actuator 22 the end of actuator 22 remote from the solenoid 18 terminates in an upturned tab 24 above the upturned tab 24 is a selector key 26 pivotally secured to selector plunger 16 by means of connecting pin 28 the selector plunger 16 extends to the right into selector body 30 in which the pneumatic apparatus of the system is contained and through intermediate elements controls the operation of yarn feed wheel 15 to the right of selector body 30 spring 34 engages the lefthand end of selector plunger 16 and biases the plunger to the right when solenoid 18 is energized the actuator tab 24 impacts against selector key 26 causing its free end to pivot upwardly where it can be engaged by cam lobe 32 that extends along the length of selector shaft 12 as the shaft 12 rocks in a clockwise direction the selector key 26 and selector plunger 16 are driven to the left causing actuation of the pneumatic system and feed system as will be described yarn strand s can be seen extending downwardly from a yarn creel not shown over a prefeed bar 36 which oscillates in timed relation with the drive shaft 14 and the selector shaft 12 to the feed wheel 15 elements of which are positioned around drive shaft 14.
