An Improved Pressure-operated Device for Actuating the Dampers of Steam Boilers and for Automatically Regulating the Supply of Liquids and Gases generally

21,741. McCoy, M. H. Oct. 10. Water and other liquid levels, regulating.-Relates to a pressure-operated device for automatically regulating the supply of fluids to tanks or boilers. Fig. 2 shows the device as used for regulating the supply of water to a tank 10. The pipe 1 communicates with steam under pressure and with a bent tube 2 adapted to operate by its distension a pinion 15 in connection with a valve on a feedpump for supplying water to the tank 10. As the water in the tank rises, a float 9 connected to one end of a lever 5 operates a valve 4 in the pipe 1, connected to the other end of the lever, and, upon the water in the. tank reaching a predetermined level, the valve 4 closes and the bent tube assumes its normal position and closes the valve on the feed-pump.
