Abstract

Ribbon 10 is lifted varied amounts through linkage 11 upon oscillation of bail 12 by typebar drive arm 13 that engages an offset ramp 14 of such bail 12. This is displaced longitudinally of its axis 15 by cams 16 carried by ratchet 17. The latter is reciprocated each print cycle by ribbon feed drive bellcrank 18. Reciprocating motion of bail 12 and ramp 14 effectively varies the lost motion between the lower end of arm 13 and bail 12 and thus varies the ribbon lift for the individual character represented by arm 13.
