Abstract

173,190. Scheffer, R. April 25, 1921. Type-lever actions.-In actions in which the key-levers and type-levers are mounted in radial slots in a segment and have pin-and-slot connection, the slots b, c for the key-levers d and typelevers i respectively are relatively displaced by an amount equal to the width of a slot, and the key-levers are provided with pins g engaging slots h in the type-levers. The key-levers and typelevers are plane and are pivoted on wires f, k. The slotted segment a is formed by die-casting.
