(under subclass 283) Subject matter wherein significance is attributed to structure of the carriage* of the typewriter or to the structure of the rail or track or component(s) that enable the carriage to move relative to the typewriter during carriage feed, or carriage return of carriage-backspace motion of the carriage.
(1) Note. In many typewriters the carriage is a structure on which the platen* is supported or mounted for intermittent or incremental rotation of the platen to effect line-space* distances. In such typewriters the platen carriage intermittently moves the platen (and the record-medium* that is held thereto) along the print-line* to effect character-space* and word-space* distances. In other typewriters the type-head carriage* is a structure on which a type-head-carrier* is supported or mounted for movement of a type-head* that includes a multiplicity of type-member* or type-face* elements. In such latter typewriters the record-medium remains stationary during the imprinting of a print-line, and the type-head carriage intermittently moves the type-along the print-line to effect character-space and work-space distances.
