Abstract: A multi-wire dot print head comprises a frame (10) and a plurality of print wires (14) supported for longitudinal sliding movement in the frame A wire driving armature is associated with each of the print wires and includes a pivotally mounted actuator lever (34) having an outer end, an inner end engaging the print wire, and a cylindrical core (35) mounted intermediate the ends. An electromagnetic actuator is associated with each of the armatures for imparting pivotal movement thereto to thereby move the associated print wire. Each electromagnetic actuator has a clindrical bore (24) that is open at one end thereof for receiving the associated cylindrical core therein and pivot support means (41) cooperating with the outer end of the associated actuator lever and defining a fulcrum for the pivotal movement of the associated actuator lever. … The print head is characterised in that each pivot support means lies in a plane normal to the associated cylindrical bore and intermediate the open end of the cylindrical bore and the position of maximum penetration of the associated cylindrical core therein.

Abstract: WIRE DRIVING ARMATURE FOR DOT PRINTER The multi-wire dot print head is provided with a plurality of print wires with a wire driving armature associated with each of the print wires and being operable to move the print wire toward a print position. The wire driving armatures each include an actuator lever and a cylindrical movable core mounted intermediate opposite ends of the actuator lever with an electromagnetic actuator associated with each of the armatures for imparting movement thereto. The outer end of the actuator lever is provided with a downwardly depending pivot leg and pivot or fulcrum support means for the actuator lever is positioned in a plane below the level of the open end of a cylindrical bore in the electromagnetic actuator so that a minimum amount of clearance may be provided between the cylindrical core and the cylindrical bore.
