Abstract

29,264. Royston, E. R., [Auto Pneumatic Action Co.]. Dec. 16. Tempo-regulating means; winding-mechanism. -Two tempo-regulating valves P, L are provided, which are operated by levers 22, 11 and control ports 15, K leading into chambers 13, G, respectively. The chamber G is connected by a port 14 to the chamber 13, which is connected by a pipe B to the motor. The ports 15, K lead into a chest H, which is connected to the exhaust-pipe F through a port controlled by a pivoted governor-valve J. The governor M is provided with the usual spring N. The lever 22 controlling the valve P is carried by a spindle 19, which rotates in bearings 20, 21. An arm 18 on the spindle 19 is arranged between springs 24, so that the lever 22 is automatically returned to the normal position when released. To rewind the tune-sheet, an ungoverned connexion may be opened between the motor and the exhaust pipe F by operating a lever 10, which opens a valve I. At the same time, the spindle driving the take-up roll is shifted and clutched to a sprocket-wheel for driving the music-roll, a pinion on the spindle being disengaged from a spur-wheel driving the take-up roll.
