Abstract:
A piano hammer stopper system includes a blocking rail movable between a first position, allowing unobstructed movement of piano hammers, and a second position, blocking at least one piano hammer from striking any corresponding strings. The piano hammer stopper system includes a drive shaft rotatably coupled to the blocking rail, a drive arm attached to the drive shaft and engaging a drive fulcrum, and a travel guide directing movement of the blocking rail between its first and second positions. Rotation of the drive shaft rotates the drive arm to engage the drive fulcrum for moving the blocking rail between its first and second positions.
