Key-board arranged according to character location:
(under subclass 472) Subject matter wherein significance is attributed to the positioning relative to one another of the key* elements that are each pressed to effect imprint of a particular character* symbol.
(1) Note. The vast majority of typewriters are manufactured so that their key-board* arrangements are the same or standard. This standard arrangement permits any typist familiar with the standard key-board to type on any typewriter without looking at the individual keys. In the typewriters of this subclass the arrangement of the keys and characters thereon is emphasized (and is usually other than standard) for various purposes. The standard key-board is also known in the industry as a "qwerty" key-board, and is so called because of the arrangement of letters along one row of keys in that key-board.
