Abstract

19,465. Northup, I. O., Northup, M. A., and Northup, E. Aug. 30. Plug cocks; hinged check valves.-A plug cock 4 for cutting off the steam or water connexion of a boiler gauge-glass 2 is provided with an internal hinged check valve 10, which is adapted to close the passage 8 in the cock upon a sudden rush of steam or water from the boiler. The valve is mounted in a chamber 9 formed by enlarging the passage 8 at one side of the cock. The seat of the valve in the side of the chamber is inclined, as shown. A stop 13 retains the valve in an inclined position, when the cock is opened.
