57 Zusammenfassung AB [EN] 223,471. Maendler, K. Feb. 14, 1924. Keyboard stringed instruments; plectra.-In a keyboard instrument in which each string is plucked by a plectrum pivoted on a pusher rod stand. ing over the end of a key, the pusher rod is also given a lateral movement the amount of which varies with the force with which the key is depressed, yielding modulated tones. A string q is plucked by a plectrum p carried by a member l pivoted at m in a slot in the pusher rod c which rod is guided in apertures in transverse bars f, g and rests on the inner end of the key a, being controlled by springs h, i. A wedge, eccentric ball, or the like b either on the inner end of the key or on the lower end of the pusher-rod transmits, on depression of the key, a lateral thrust to the pusher-rod which in rising also pivots in the aperture in the bar g. A bevelled abutment k and an adjustable abutment r are provided in the slot for the plectrum-carrier l, which is returned to its central position by springs n, o.
