Damper assembly for pianos

An improved damper assembly for a piano comprising:

• a damper head arranged relative to an associated string of the piano;
• at least one damper felt disposed between said damper head and said associated string;
• dual-staged applying means for applying first and second staged damping actions to said associated string;
• said dual-staged applying means being operatively associated with said damper head so that only large amplitude components of string vibrations are damped by the first staged damping action and the remnant of string vibration is almost fully damped by the second staged damping action;
• said dual-staged applying means including a leaf spring disposed at a central section of said damper head;
• and
• said at least one damper felt being disposed on the bottom of said leaf spring.

• said at least one damper felt being of a triple layered construction having a first layer of felt material facing said string, a second intermediate layer of felt material, and a third layer of felt material facing said damper head, said second layer of felt material being intermediate said first and third layers and being softer than said first layer of felt material, and said third layer of a felt material being softer than said first and second layers of felt material.

• said at least one damper felt being disposed on the bottom face of said damper head at a central section thereof, and being made of a felt material of a predetermined hardness;
• said dual action applying means including two additional damper felts disposed on the bottom face of said damper head at longitudinal end sections of said damper head on opposite sides of said at least one damper felt, said two additional felts being made of a felt material which is softer than the felt material of said at least one damper felt;
• and
• said two additional damper felts extending downwardly a prescribed distance beyond the bottom face of said at least one damper felt.
