DEFINITION

Classification: 400/553

Via line-space/carriage-feed-release actuator:

(under subclass 545) Subject matter wherein significance is attributed to structure on the typewriter that performs the following operations substantially concurrently: (a) the platen* is caused to be turned through one or more increments, and (b) the carriage* is enabled to be moved in a carriage-return direction opposite to the character-space* direction, and (c) the structure that normally engages a portion of the carriage to move the carriage in the character-space direction is temporarily disengaged, whereby the carriage-return movement is made relatively quiet.

(1) Note. In the typewriter of this subclass the structure is directed to means for line-spacing* which also, by some connection to the carriage feed, effects release of the carriage feed for purposes as stated in the definition. For structure to cause carriage feed release, see subclasses 334+ above.
