Type action for a power-driven typewriter
摘要:
A simplified type action for a typewriter comprising a type bar linkage having a toothed driving pawl pivotally mounted on an intermediate lever connected to a type bar through a link, and a key lever linkage including a key lever having a hooked lever pivotally mounted thereon and adapted to be engaged by a blade or tooth on a constantly rotating power or snatch roll to initiate a cycle of printing operation. The trigger lever is yieldably pivotable by the driving pawl upon its return stroke to assure the restoration of the type bar linkage to its normal position. Motion transmitting means best suited for such type action is also disclosed in which the power roll is composed of a center shaft and a toothed member rotatably mounted thereon, and an energy storing motion transmitting spring connects and is adapted to impart the motion of the former to the latter.
