DEFINITION

Classification: 400/456

Type-bar or type-member guide structure:

(under subclass 383) Subject matter wherein significance is attributed to means located on the frame of the typewriter or located adjacent to the print-point* of the typewriter, which means serves to confine the movement of a type-bar* member that is approaching the print-point into a path that will insure the correct positioning of a type-member* (i.e., a type-face* element or a type-die* element) relative to the print-point.

(1) Note. In this subclass the guide means is located in the vicinity of the pivot axis of the type-bar.
