Abstract

13,494. Brower, J. D. June 6. Lift valves; actuating.-A valve-device for permitting the escape of air from water mains without the escape of water comprises a branch pipe 12 on the main 10 provided with an air vent 14 controlled by a piston-actuated lift valve 22, and protected by a perforated hood 16. The lift valve 32 is secured to the piston 17, which works in a cylinder 18, by a screwed pin 20 provided with a tapered head 21 adapted to take in the aperture 14 in the valve seat 19, and with an extension 40 adapted to work in a guide-aperture 24 in a chamber 23. A small aperture 26 connects the branch pipe to the outlet, and a passage 31 controlled by an auxiliary lift valve 28 supplies air to the underside of the piston. The auxiliary valve and consequently the main valve is held open when there is no water in the main by an adjustablyweighted lever 33. The valves are closed when the water reaches the branch pipe by the weight of water in a container 39, which is coupled to the lever 33 by a link 46, the water entering through a flexible connexion 42 and driving the air out through a similar connexion 43.
