Abstract: A serial printer which includes a print element which traverses back and forth in front of the paper. The print element is in the shape of a cup. The sides of the cup are formed by a plurality of fingers, each of which has a number of characters thereon. A hammer is located in the center of the cup. The fingers can be selectively raised whereby any one of the characters on each finger can be moved to the print position. Printing is accomplished by rotating the cup so that the desired finger is located between the hammer and the paper. If necessary, the finger is raised so that the desired character is positioned in the print position. The hammer is then fired to print the desired character.

Abstract: 1327358 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 12 June 1972 [1 July 1971] 27303/72 Heading B6F In a printer having print hammers 16 striking a document 14 against type fingers and provided with a platen 40 to support the type fingers, the platen is displaceable out of alignment with the type characters on the type fingers to permit a line of type to be viewed. The type fingers are formed on an endless type band 24 driven round wheels as at 34. The platen 40 forms part of a T-shaped structure 12 pivoted at 44 and displaceable by a pull rod 56 actuated by a solenoid. The apparatus is applied to a keyboard operated machine wherein control circuitry acts to lower the platen whenever a delay of 1À2 seconds is detected between key operations.

Abstract: 1300787 Electromagnetic actuators INTERNATIONAL BUSINESS MACHINES CORP 10 Dec 1970 [22 Dec 1969] 58653/70 Heading H1P [Also in Division B6] A print hammer actuator assembly comprises a yoke 141 carrying an electromagnet winding 144 and pivotally supporting an armature 148, the yoke 141 itself being pivotally mounted at 138 on a support 139. A spring 135 urges the yoke 141 against a stop leg 139b. The armature 148 is coupled to a print hammer 160 by a connecting rod 182 which is urged against the armature by spring 184.
