18,460. Broadhead, J. B. Aug. 17. Water supply.-In a device for regulating water, steam, or other fluid pressure, when the pressure on the exit side of the weighted main valve B becomes too great, the secondary valve F is closed and the valve E opened through the medium of a lever D and piston C, allowing water to pass through the cock J and valve E to the back of the piston G. The valve B is thus closed. When the pressure on the outlet side falls, the reverse action takes place and the valve B opens. In the Provisional Specification, a form is described having modified details; In case of fire, the valve J is closed.
