Patent number: 4209260Abstract: A wire matrix print head having print wires subject to wear at their printing ends are biased by return springs against one side of one end of armatures, the other sides of which bear against a gap adjusting ring. The other end of each of the armatures is spaced by a predetermined gap from the pole piece of associated electromagnets which, when energized, drive the armatures about pivots intermediate the ends of the armature against the bias of the return springs. The ends of the armatures are formed with a step on the side initially placed in contact with the drive end of a print wire so that when the print wires are worn the armatures can be flipped over to present the unstepped side in contact with a drive wire with the result that upon movement of the adjusting ring to restore the gap between the armature and pole piece the print wires are pushed to a rest position closer to the printing plane by the depth of the step.Type: GrantFiled: December 29, 1978Date of Patent: June 24, 1980Assignee: Triumph Werke Nurnberg, A.G.Inventor: Friedrich Jung

Patent number: 4203304Abstract: A flexible shaft coupling for connecting a drive and a driven shaft comprises an axially stacked plurality of flexible metal discs which are connected to one another at oppositely spaced peripheral points with the directly connection between one disc and its neighboring disc on one side being displaced 90.degree. from the interconnection with the neighboring disc on its other side. The coupling is particularly suited to transmit torque yet allow movement of the driven shaft axis relative to the drive shaft axis. The invention has particular application to small precision mechanisms such as a single element typewriter wherein the single element typehead, secured to the driven shaft, must be capable of being rotated and tilted to position a desired character opposite a printing point.Type: GrantFiled: November 8, 1978Date of Patent: May 20, 1980Assignee: Triumph Werke Nurnberg A.G.Inventor: Herbert Decker

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.
