ABSTRACT:
A harpsichord action characterized by a vertical disposition of the strings which extend downwardly from a wrest plank located slightly above the keyboard. The keys, which are half the conventional length and hinged at their inner ends, are connected with jack levers located above the keys and in front of the strings. The jack levers are connected with jacks which are pulled forwardly by the jack levers upon depression of the keys. Each rank of jacks is controlled by a single jack guide which is selectively shifted by a cam mechanism operable from the keyboard.
