ABSTRACT:
A typewriter comprising a shiftable carrier supporting a rotatable type drum having a plurality of circumferentially extending rows of type characters thereon. Typing keys, when depressed, condition actuators and cause engagement of a power driven cyclic action clutch which drives a power bail to operate a conditioned actuator to rotate the type drum from any position it may be in to a new position to align a type character corresponding to the key depressed with the printing point. Certain of the keys, when depressed, position stops to limit axial movement of the type drum by the action clutch to align an appropriate one of the rows of type characters with the printing point. The action clutch also actuates a centralizer to accurately align the type drum prior to printing and, in addition, causes printing. A cyclic carrier shift clutch is engageable by the action clutch and by certain carrier shift control keys.
