摘要

A keylever touch control mechanism for typewriters includes keylevers mounted on a common pivot which spans the distance between the spaced side frames of the typewriter. The keylevers are supported in their rest position by a plurality of underlying leaf springs. Keylever touch is controlled by the amount of force exerted on the underside of the keylevers by the leaf springs. A spring loaded pivotal bail having rigid extensions underlying the leaf springs pivots into abutment with the springs to vary the tension of the springs. A detented control mechanism is coupled to the bail to pivot the bail extensions into and out of abutment with the leaf springs. When the bail extensions are pivoted into abutment with the leaf springs and a keylever is depressed, the force required to overcome the biasing force of the spring loaded bail extensions to depress a keylever is increased and the keylever touch is correspondingly increased.PPWhen the bail extensions are pivoted out of abutment with the leaf springs and a keylever is depressed, the leaf springs are deflected independent of the bail extensions and therefore the force required to depress a keylever is decreased and the keylever touch is correspondingly decreased.
