Patent number: 4198169Abstract: 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.Type: GrantFiled: September 6, 1978Date of Patent: April 15, 1980Assignee: Adlerwerke vorm.

Patent number: 4105106Abstract: A normally engaged toothed cone clutch mechanism to allow disengagement of the platen of a typwriter from a line indexing ratchet wheel to enable rotation of the platen independently of the ratchet wheel includes a clutch member and a connection between the clutch member and the ratchet wheel. The connection takes the form of a spring washer secured to the clutch member and pins extending axially from the ratchet wheel toward the clutch member. The spring washer is formed to embrace and grip the pins to transmit rotary motion of the ratchet wheel to the clutch member without play yet allow axial sliding movement of the clutch member to disengaged position while maintaining its connection to the ratchet wheel.Type: GrantFiled: January 27, 1977Date of Patent: August 8, 1978Assignee: Adlerwerke vorm.
