摘要

Plate (1) has on its upper side two sloping planes (2) on which a pin (4) of a lever (3) slides to tension a pressure spring (5) so that the lever after the highest point of the plane quickly drops downward and a ball (6) falls into a hemispherical cage (7). The lever as an articulated lever pushes the ball back into the starting position. At the same time the lever moves a ball (8) in a cage (9) having a sloping surface (10) toward the back to produce various movements of the ball.
