ABSTRACT:
A sostenuto piano action is provided for upright pianos. Each damper is provided at the top rear thereof with a rubber fitting having a catcher flange or tab thereon. A pivoted sostenuto knife similar to that in a grand piano has a blade thereon which, upon pivoting of the sostenuto knife, will catch or engage the catcher tab or flange of each fitting to retain retracted such dampers as are in retracted position. With the knife pivoted to sostenuto position and additional notes played thereafter the flanges will bump the backside of the knife, but will not be caught. Spring biased elbows or hinges are provided in the damper levers to allow "breaking" of the levers at such time so as to avoid providing a strange feel to the pianist. The rubber nature of the fitting prevents any noise at such time.
