Abstract

23,448. Boult, A. J., [Wilcox & White]. Oct. 13. Tempo-regulating means; controlling handles. -In a piano-player, a bellows J<7> controls a valve J<5>, which governs a port J<3> connecting the passage I leading to the wind-chest B, and the passage K leading to the motor. The position of the valve may be varied by means of a pivoted finger-push N. The bellows J<1> is controlled by a spring mounted on a pivoted block, the position of which can be varied by means of a screw. The push N is connected by links N<2>, N<3>, N<4> to the movable board of the bellows, so that, by depressing it one way or the other, the valve J<5> may be opened or closed, thereby varying the speed of the motor H. The usual levers F, L, M are provided for operating the expression pedals, and controlling the tempo and rewind valves respectively.
