Abstract: An electromechanical printer having characters of a type font located on radial spokes of a circular type disc is disclosed. The type disc is normally arrested and connected to be driven about its axis by a unidirectional motor source via a slip clutch. Selection-print activating mechanism responsive to source, e.g. keyboard, generated mechanical outputs serve to select a character stop, in an assembly of character stops, corresponding to characters located on the spokes of the type disc and, incident to selection of a character stop, to release the normally arrested type disc. The type disc is provided with counterstops adapted to engage selected character stops positioned in the path thereof and to move the character stop assembly to a frame supported final positioning stop which arrests the type disc with the selected character opposite a print point.

Abstract: A tabular stop assembly having two sets of uniformly spaced tab stops for use with a typewriter with a dual pitch escapement wherein individual stops of each set are formed on each of an array of uniformly spaced C-shaped tabs which are mounted for rotative movement relative to a tab rack to first and second set positions corresponding to a selected escapement pitch.
