DEFINITION

Classification: 400/268

For shifting type-face or type-bar:

(under subclass 251) Subject matter wherein case-shift* is effected by moving a type-face* or by moving a type-bar* relative to the typewriter platen*, the direction of such movement being considered to be parallel to a plane in which the print-point* lies, thereby causing a chosen type-face to be impacted against a record-medium* at the print-point.

(1) Note. The type-face may be one of many type-faces on a type-head* containing a type-set-assemblage*, in which event case-shift occurs by moving the type-head so that the chosen type-face will be in position to be impacted. Or the type-face may be movable relative to a type-bar that carries only two (or three) type-faces.
