DEFINITION

Classification: 400/319

Carriage-feed mechanism (e.g., escapement, etc.):

(under subclass 283) Subject matter wherein the carriage* is caused or enabled to be moved in a direction that enables the character* symbols to be imprinted in succession (i.e., the character-space* direction), and wherein the movement in said direction is regulated to occur in regular or equal increments of movement, each increment corresponding to a character-space distance or a word-space* distance.
