(under subclass 139) Subject matter wherein the typewriter is provided with a member that is (a) cylindrical or cylindroidal, (b) rotatable about an axis that extends through the cylinder parallel to the circumference of the
cylinder, and (c) supporting a plurality of type-set-assemblage* groups of type-face* elements on the circumference of the cylinder.
(1) Note. Usually the type drum extends in length to substantially the full width of the record-medium* and each of the type-set-assemblages extends around the circumference of the type drum. The number of type-set-assemblages provided on the type drum corresponds to the number of character* symbols and character-space* distances that may be included within the width of the record-medium. Selection of type-face for the first character of a print-line* is made from the first type-set-assemblage and selection of the second character of that print-line is made from the next adjacent type-set-assemblage, the action being repeated until the entire print-line has been imprinted.
