Abstract
A B/B flat thumb key mechanism with a diagonally arranged rod 1 which is equipped with two rockable levers 2, 3 arranged on rotatable tubular hinges for transmitting the movement of the B key to the B flat key on the main rod 4 via a driver 3A. The diagonally arranged B/B flat thumb key rod makes possible a double extended rod which brings about greater wear resistance and greater stability, and also makes possible the use of needle springs in the B/B flat thumb key mechanism, which provides a uniform spring action in relation to the main mechanism. <IMAGE>
