PRESSURE-REDUCING VALVE.
Application filed May 26, 1916,
To all whom t may concern:
Be it known that I, JOHN citizen of the United States, borough of Brooklyn, city of New York, i the county of Kings and State of New York, have invented certain new and useful Improvements in Pressure-Reducing Valves, of which the following is a specification.
My invention relates to water regulator valves in which the street main pressure must be reduced on one side of the valve and it is my object to construct a simple valve which will be mechanically strong, simple in its operation and which will not easily get out of order, through which a maximum of water will flow, which can be easily regulated from the outside, in which the counter balance may be released to obtain full main pressure if desired and which will be easily accessible for repairs.
In the drawing Figure l is a sectional view of the valve in closed position; Fig. 2 a top View and Fig. 3 a modified control device.
rIhe valve comprises a casing l having the inlet chamber 2 and outlet chamber 3, divided by the valve seat- 4;. A cylinder 5 is located above the outlet and has its upper end in free communication therewith through the passage 6, The upper part of the cylinder is slightly enlarged to facilitate removing and inserting the piston.
'Ihe stem 7 carries the valve 8 at its lower end and the piston 9 within the cylinder with the copper bucket 10 below the piston. This valve stem 7 projects through the top of the casing and a eounterbalance in the form of a spring l1 bears on the stem with the stirrup 12 holding the upper end. rllhe nuts 13 bearing on the bar 14 form means for adjusting the spring pressure.
In use the full nain pressure of say 1.00 pounds enters the inlet chamber 2. If 40 pounds pressure is desired on the outlet side the spring 11 is adjusted to counterbalance a 60 pound pressure. The main pressure will then raise the piston 9 allowing the water to enter the outlet chamber 3, passage 6 and upper part of the cylinder 5 until a pressure of 40 pounds is exerted on top of the piston when the additional pressure of 60 pounds from the spring will close the valve and no more water can pass from the J. TAGUE, a residing at the Spcoioation 0i' Letters Patent.

inlet chamber to the outlet Chamber until the pressure in the latter is reduced by drawing olf water when the piston will rise carrying the valve with it until the balance is restablished when the valve will close.
In my valve the maximum volume of water will pass the valve when open owing to its large size and full lift and when closed the full main pressure on the top of the valve holds it firmly on its seat to prevent slow leakage. The copper bucket l0 being at all times forced against the cylinder walls prevents grit and sand reaching thegpiston and its packing and interfering with the smooth operation of the valve.
In use on lire extinguisher stand pipes it is sometimes desirable to quickly obtain the full main pressure when long lines of hose are in use and in such eases I use the counterbalance adjustment shown in Fig. 3 in which the stirrup l2 is solid and is threaded with the hand wheel and hollow nut 16 running up and down therein. When the full pressure is required the hand wheel is run up relieving the spring pressure thus obtaining the full main pressure in the out let.
I claim l. A regulator valve comprising an inlet chamber, an outlet chamber and a valve seat between the two, a cylinder above the inlet chamber, an open passage between the outlet chamber and the upper part of the cylinder, a valve stem extending through the cylinder and inlet chamber, a valve on the lower end thereof, an imperforate piston thereon within the cylinder and Counterbalancing means on the upper end of the stem.
2. A regulator valve comprising an inlet chamber, an outlet chamber and a valve seat between the two, a cylinder above the inlet chamber, an open passage between the outlet chamber and the upper part of the cylinder, a valve stem extending through the cylinder and inlet chamber, a valve on the lower end thereof, an imperforate piston thereon within the cylinder, a bucket washer on the stem below the piston and counterbalancing means on the upper end of the stem.
3. A regulator valve comprising an inlet chamber9 an outlet chamber and a valve seat between the two, :i cylinder above the inlet ineens for relieving the counterbalancing hzunber, an open passage between the out pressure. l@ let chamber and the upper part of the Cyl- In testimony whereof I have affixed niy incler, a valve stein extending through the signature in the presence of two witnesses.
