DEFINITION

Classification: 400/91

STENOGRAPHIC TYPEWRITER:

(under the class definition) Subject matter wherein significance is attributed to a typewriter intended to be used while typing in "shorthand" or stenos:graphically.

(1) Note. Various terms are used in the art to refer to such a typewriter, including "shorthand", "steno-typograph" and "tachys:graphic", and variations of such words. A typewriter capable of stenos:graphic operation has a distinctive appearance that is different from that of the usual typewriter. The keyboard* is arranged so that plural key* elements are pressed simultaneously by the fingers of one or both hands of the typist, and the type-face* elements are impressed against the record-medium* simultaneously in groups. The imprinted character* symbols therefore appear in the record-medium in groups, and the record-medium, which is usually a relatively narrow strip of elongated material, is moved after each group of characters have been imprinted thereon. The stenotypist thus forms groups of characters in succession, each group corresponding to a syllable of a word*, thus the operation of such a typewriter can be rapid and can be used while recording a spoken conversation.
