DEFINITION

Classification: 400/435

Type-bar rebound preventer (e.g., via latch, brake, linkage, etc.):

(under subclass 383) Subject matter wherein significance is attributed to means for retarding movement of a type-bar* that is returning from its print-point* position to its rest position, whereby the type-bar will not spring back from its rest position.

(1) Note. The intent of rebound control is to prevent or minimize a second movement from its rest position to its print-point position so as to prevent multiple images. Rebound control includes structure such as a latch, a brake, and an arrangement of linkages similar to a toggle-linkage* assemblage, which structure tends to prevent rebound in spite of the force with which the type-bar is returned to its rest position.
