Abstract
Apparatus for displacing a working member both vertically and rotationally is disclosed. A shaft is slidably mounted within a sleeve mounted for rotational displacement within a frame. A working member is secured to a hub which is secured to the shaft such that it may be both vertically displaced and rotationally displaced. A yoke assembly is connected between a vertical actuator and the shaft for effecting vertical displacement of the shaft without limiting rotational displacement. Additional means are provided for rotating the sleeve to effect rotational movement of the shaft. The sleeve is connected to the shaft such that rotational movement of one causes the other to rotate without limiting sliding displacement therebetween.
