Automatic self-regulation for musical instrument string tuning - involves shaft on which string is located winding string on when reversed with tension produced by arm working with curved track

摘要

Three rollers are located between the arm (9) and the curved track (7) and hold a carriage which draws a steel line with a spring. The blockade of the string works with the aid of a bolt (21) which locates on the steel line. A plate (19) swings during vibration and a part blocks or unblocks the string. A tooth (12) blocks the complete bridge which is held by four screws. USE/ADVANTAGE - An arrangement for a player of a musical stringed instrument whereby the instrument is tuned once and then adjusts itself without intervention by the musician.
