PIANO DOUBLE REPETITION MECHANISM Russian patent published in 2014 - IPC G10C3/16 

Abstract RU 2519915 C1

FIELD: physics.

SUBSTANCE: piano double repetition mechanism comprises at least one spring (22), at least one adjustment screw (23) connected to one end of the spring (22), and at least one angle section (24) in form of interconnected shelves, which is mounted with the outer surface of one shelf on the top surface of the jack damper. In the other shelf of the angle section there is at least one opening in which said adjustment screw (23), which is connected to one end of the spring, is inserted. The spring (22) exerts pressure through its other end on the top part of the jack (8).

EFFECT: easier installation of the piano double repetition mechanism into a piano mechanism overall, without dismantling the latter.
