VALVE.
vPATENT OFFICE.
SPECIFICATION forming part of Letters Patent No. 608,454," dated August 2, 1898.
Application iiled December 29, 1897. Serial No. 664,218. (No model.)
v1897, No. 595,061.
It isthe object of the present invention to improve the construction shown in the patent referred to and to produce a valve which can be closed automatically with a pressure equal on each side, so as toavoid any reaction on the pipes connected therewith.
In the accompanying drawings I have illustrated my invention, in which- Figure l is a sectional View of the valve. Fig. 2 is a front view, and Fig. 3 a rear view, of the coupling containing the operating parts. Fig. 4L is a sectional view of a modiiication. y
The invention is adapted for use on railway stand-pipes, water-plugs, and fire-hydrants, and is also capable of use where water is runl to a tank with a ball-float to operate the supplemental valve.
v In the drawings, A represents the inlet-passage, and B the outlet-passage. In a chamber vmade'intermediate of the inlet and out? the diaphragm there is a bearing provided for the entire surface of the diaphragm, and there is no pressure upon unsupported parts, as in my former construction. Above the diaphragm is located a pressure-chamber O,
and this is in communication with the inlet-j .port A through a passage a, which enters the pressure-chamber O through a horizontal con- Y tinuation D of the passage a. A valve c, car-v ried on a stem d, closes the opening of the pipe b in its abnormal position, but normally leaves the passage free, a spring e keeping the valve and stem retracted. Thus in its normal position the yforce of the water is exerted on the upper side of the diaphragm and keepsthe exit-opening closed. The spindle d projects outside ofthis casing, and by forcing this :in to close the exit-opening of the pipe Z) the flow of water above the diaphragm :is stopped, and the pressure exerted against the under face of the cylindrical cap O will force thisY upward and the water contained above the diaphragm will flow out from the chamber around the spindle (l and out at the opening f, while the cylinder-cap will be raised from its seat and the water will iow around the piston D and out lthrough the exit-opening B. In ordernto make a cushion eiect, the cap C has an air-tight connection with the cylinder D, and the air-space g is.
controlled by a pipe 71 extending through the piston and the bottom of the casting and provided with a cock 't'.
The flow of water may be regulated to the chamber O by the screw 7c, which is used to contract the passage a., as may he found desirable.
In Fig. 4 I have shown a modification in which the piston D is open at its upper end, and with this construction it may not be necessary to have the relief-valve, though I may use it or not, as may be founddesirable.
I claiml. In a valve, an inlet-passage and an outlet-passage, a piston arranged intermediate of the openings, a cylindrical cap surrounding the upper end of the piston, a diaphragm secured to said cap, va pressure-chamber above the diaphragm and means for controlling the pressure to said chamber, substantially as described.
2. In a valve, a stationary piston, a cylindrical cap surrounding the upper end thereof, the diaphragm secured thereto, a pressure-chamber above the diaphragm an inlet to said chamber, an outlet from said chamber and a val ve controlling the inlet and outlet ports, substantially as described.
3. In a valve, a piston located intermediate of the inlet and outlet ports, a cylindrical cap closing the passage around the piston, adialphragm secured to the cap and an air-chamber between the cap and piston, substantially as described.
In testimony whereof I afx my signature in presence of two witnesses.
