EDGAR M. MOORE, OF PITT$BURGH, PENNSYLVANIA.
HYDRANT.
Application filed August 23, 1917.
To all whom it may concern. 4
Be it known that I, EDGAR M. MOORE, a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in I-lydrants; and I do hereby declare the following to be a full, clear, and exact description thereof.
This invention relates to automatic cutoff hydrants, and more particularly to a hydrant of this class that will utilize the pressure of the fluid passing therethrough to operate the cut-off mechanism.
The principal objects of the invention are to provide a hydrant that will eliminate the necessity of cut-off valves in pipe lines, and to generally improve the art of hydrants and spigots or faucets by providing means for the escape of water above the valve and other novel details of structure which will be more fully brought out in the specification.
In the drawings I have shown one preferred embodiment of my invention, but it will be understood that various changes in structure and design may be made by a mechanic skilled in the art to which this invention belongs without departing from the spirit of my invention as defined in the appended claims.
In the drawings Figure 1 is a vertical sectional view through a hydrant constructed according to my invention;
Fig. 2 is a detail view showing the construction of the cut-0E mechanism; and
Fig. 3 is a top plan view of the cut-off valve.
Referring more particularly to the drawings, the numeral 2 designates the main casing of my hydrant having a screw top portion 3 of ordinary construction and having the usual inlet and outlet portions 4 and 5 respectively.
The valve portion of the hydrant comprises a post member 6 of variable diameters decreasing toward the lower end. Mounted on the post as at 7 are a plurality of circular members 8 having apertures therein and being preferably of spider con-' struction. There are preferably provided three of the members 8 and mounted between the members and held in place by the clamping action thereof are washers 9 Specification of Letters Patent.

adapted to frictionally engage the inside face of easing 2.
Mounted below and abutting the members 8 is a valve member 10 having a valve face 11 adapted to seat on the valve seat 12 formed around the inner circumference of the casing 2. Suitable locking or securing means such as a washer or ring 13 and nut 1a are provided for holding the valve member in place.
Adjacent the lower end of the casing member is an inwardly extending flange 15 adapted to normally support a valve member 16 having a tubular downwardly extending stem 17 having a closed lower end and an open upper end. The post 6 has its lower end inserted in the tubular stem 17 and is adapted to freelyrotate therein. The under side of the valve seat 12 is beveled forming a seat 18 for the valve 16.
When the valve member 10 is closed the post or stem 6 will force said valve 16 downwardly into tight engagement with the shoulder or flange 15, thereby providing an auxiliary or extra cutoff for the main water supply, preventing pressure against the flexible face 11 of the valve 10.
The casing 2 has small apertures or drain exits 19 on its end spaced above the valve seat 19, a sufficient distance so as to be open when the valve 10 is seated and to be closed by the valve 10 when it is raised or unseated. It will thus be seen that any liquid remaining above the valve 10 after it is seated will escape through the exits 19 and prevent freezing.
A screw threaded operating stem 20 of well known construction is revolubly mounted in the upper portion of the casing and passes through a suitable stuffing box 2-1. The stem 20 has its lowered end squared as at to loosely engage a socket 23 in the upper end of the post 6, and is provided on its upper end with an operating wheel 24-.
The operation of my device is as follows: Liquid under pressure enters the inlet 4 and is stopped by the valve member 15. To cause the liquid to flow through my hydrant. the stem 20 is rotated by the hand wheel 2!: thereby allowing post 6 to rise within the ca sing 2. As the post rises within the casing 2., the pressure of the liquid will force the valve 16 upwardly thereby allowing a passageway around said valve for the liquid so that it may force upwardly against the valve 10, thereby unseating said valve and allow-' ing a continuous How of liquid upwardly through the spider formed members 8 and outwardly through the outlet portion 5 of my hydrant. v
Provided that the valve members or washers 12 or 9 or any other portion of the post/9 becomes worn or broken, the top portion of the hydrant may be disassembled and the post removed without in any manner shutting off the pressure of the liquid. However, the liquid will not flow through the disassembled hydrant for the reason that the valve 16 or automatic cut-off would be forced by the pressure of liquid upwardly against the valve seat 18 thereby preventing any further flow of the liquid.
Although I have shown and described my improvements as pertaining to hydrants, it will be readily seen that they may be applied to-the ordinary form of spigot or faucet, and I wish it expressly understood that such application of my improvements is within the scope of the appended claims.
Having thus described my invention, what I claim is 1. In combination with a casing having a valve stem and valve therein, and an automatic cut-off valve loosely mounted in the lower end thereof adapted to be seated by the pressure of liquid within said casing when said valve stem is removed and to be normally held open by said valve stem, said cut-ofi comprising a valve member provided with a tubular stein having. a closed bottom end and an open upper end and said stem being adapted to receive the lower end of said valve stem.
2. A hydrant of the class described comprising a casing, a vertically movable main valve stem mounted within said casing, a valve on said stein, said main valve stem projecting below said valve an appreciable distance, and an automatic cut-0E valve loosely mounted in the lower end of said casing and comprising a valve member provided with a downwardly projecting tubular stem portion having a closed bottom, said projecting portion' of said main valve stem being adapted to fitwithin said tubular stem of said lastnamed valve to guide and control the movement thereof.
3. A hydrant olthe class described, comprising. a casing, a vertically movable main valve stem mounted within said casing, a valve on said stem, said main valve stem projecting below said valve an appreciable distance, and an automatic cut-ofi' valve loosely mounted in the lower end of saidlcasing and: comprising a valve member provided with a downwardly projecting tubular stem portion having a closed bottom, said projecting portion of said main valve stem being adaptedto fit within said tubular stem of said last named valve to guide and control the movementthereof, a seat formed within said casing against which said cut-oi? valve is adapted to seat when said main valve is-v withdrawn from said casing, and an inwardly extending flange at the lower end of said casing against which said valve is adapted to seat when said main valve is closed.
In testimony whereof, I the said EDGAR M. Moons have hereunto set my hand.
