DEFINITION

Classification: 400/321

With repeat spacing:

(under subclass 319) Subject matter wherein the carriage* is urged to be moved in successive increments of movement (the increments corresponding to character-space* distances) a plurality of said increments occurring upon the pressing of one key* element on the key-board*.

(1) Note. The typewriter of this subclass is usually one that is electrically powered, thus enabling repeat spacing with one pressing of a space key or space-bar*.
