DEFINITION

Classification: 400/139

INCLUDING TYPE-SET-ASSEMBLAGE MOUNTED ON CARRIER AND RELATIVELY MOVABLE FOR SELECTION AND FOR IMPACT OF TYPE-FACE:

(under the class definition) Subject matter wherein a typewriter is provided with a type-head-carrier* or with a type-face-carrier*, either of which carriers supports a type-set-assemblage* for movement of the type-face* elements thereon relative to the record-medium*, whereby any of the type-face elements may be selected or chosen to be impressed against a record-medium and the selected or chosen type-face element may be impressed to imprint a character* symbol.

(1) Note. The definition of type-head- carrier in the Glossary, section III, discusses the difference between a type-head-carrier and a type-face-carrier. Briefly, a type-head-carrier supports a type-head* wherein all

type-faces are integral one with the others, whereas a type-face-carrier supports type-faces that are movable, one with respect to the others. The difference between "selected" and "chosen" is also discussed in the Glossary under the definition of case-shift* and other definitions. Briefly, a particular type-face is selected from among the many available from a type-set-assemblage whereas an upper-case* form of letter (as distinguished from a lower-case* form of the same letter) is chosen from the forms available on one key* element.

(2) Note. In some typewriters movement of the selected or chosen type-face for impact is a relative movement; that is, in these typewriters the platen* (and the record-medium supported thereby) are moved toward the selected or chosen type-face, whereas in most typewriters the type-face moves toward the platen.

(3) Note. The definition of type-bar-segment* discusses the differencebetween a type-bar-segment and a type-face-carrier. Briefly, a type-bar-segment supports a type-set assemblage for case-shift movement (i.e., choice of upper-case or lower-case), whereas a type-face-carrier supports a type-set- assemblage for selection of type-face from among many type-faces as well as for choice of upper-case or lower-case.
