UNITED STATES CHARLES W'- MENIGE, OF PHILADELPHIA, PENNSYLVANIA.

answer.

Application filed May 6,

T all whom it may concern Be it known that I, CHARLES W. MENIGE, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Hydrants, of which the following is a specification.

This invention relates to hydrants and more particularly to an improvement upon the device shown in my prior Patent, No. 1,316,799, dated September 28, 1919, and includes a stop and waste cook or turn plug valve operative to control the flow of water through the hydrant and which will serve to drain the hydrant when the valve is closed so as to prevent freezing.

Among the objects of the invention are to improve the valve construction and to permit the supply pipe from the main to be connected thereto with greater facility and less cost; to encase thewater conducting pipe so that soil cannot penetrate through the joints of the hydrant standard to interfere with the operation and cause excessive wear on the stop cock or turn plug of the valve and the seat thereof, and to generally improve and simplify theconnection of the operating parts of the valve.

In the accompanying drawings,-

pipe 6 thereto, said pipe extending down through the portion3 of the standard, which portion is enlarged relative totlieupper per tion 1 but reduced relative to the flange portion 2 to give support to the hydrant when embedded in the ground. The lower portion 3 of the standard is shown broken away but may be extended indefinitely so as to cover the valve parts now to be described.

Connected to the lower end of the pipe 6 is a valve casing 7 having its lower end providedwith a reduced externally threaded portion 8 'or otherwiseequipped for direct connection to a supply pipe for water from the main whereby the use of a special union or slip joint is obviated. The upper portion of the casing 7 has its bore enlarged with respect to the pipe 6 to provide an outlet chamber 9, and intermediately there is provided a circumscribing restricted portion 10 forming art of a frusto-conical valve seat 1131 in which a turn plug 12 has a grinding The turn plug 12 is closed at its lower end and is formed with a chamber 13 hav ing an inlet port 14 at one side coinniunicating with the upper end of a conduit 15 outwardly off-set from the lower portion of the casing and communicating at its lower end with the inlet passage 16. A web 17 forms part of the seathfor the turn plug through which seat the upper end of the conduit, extends and the passage 16 is normally open at the top but is closed by the lower end ofthe plug, thus permitting free downward movement of the plug as the surfaces of the plug and seat wear in use.

The upperend of the plug projects into theoutlet chamber 9 and the upper end of the chamber IShas outlet ports 1.8 openi1ig through opposite sides of the wall or the plug into the chamber The upper cylin drioal portion of the plug is smaller than the chamber 9 so as to rovide an annular space around the plug at the out-lets 18 in the enlarged upper bore portion of the casing 7. In this space are provided two stop shoulders or

lugs

19 and 20 arranged sub stantially atright angles to each other and engaged by a pin 21 projecting from the turn plug so as to limit the rotation of the latter. In addition, the lower portion of the casing 7 in line with the inlet port 14 is provided with a drain port 22 in the form of an extension to whicha drain tube 23 may be coupled as indicated at 2 1.

The upper end of the turn plug 12 is provided with a polygonal socket 25 receiving the lower end of a correspondingly shaped stem 2". The stem 26 extends through the pipe 6 and the upper portion 1 of the standard and has mounted on the upper end thereof, a frustoconical enlargement 27 having a reduced downward projection 28 provided with a polygonal socket 29 receiving the upper end of the stem 26. Also disposed in the socket 29 between the upper end of the stem and the end wall of the socket is an expansible spring 30 which normally tends to hold the plug 12 firmly seated to prevent leakage. A cap nut 31 is mounted on the upper end of the standard and has a tapered opening 32 against which the en- '1 largement 27 seats with a grinding fit so as to prevent leakage at this point and the enlargement has a polygonal extension 33 for engagement by a detachable handle 34 by which the stem and valve may be turned to turn the hydrant on or off. An expansible spring 35 is disposed between the lower end of. the projection 28 and the shoulder pro duced in the standard or upper end of the pipe 6 and together with the spring 80, serves to hold the enlargement 27 seated.

In the operation, the handle 34 is swung so as to turn the stem 26 through its sliding engagement with the enlargement 27 and through the connect-ion of the lower end of the stem with the turn plug, to turn the plug so that the port 1 1 will be aligned with the conduit 15. ater will then flow through the passage 16, conduit 15, inlet port 1 1, chamber 13, outlet ports 18, chamber 9, pipe 6 around the stem 26, upper portion 1 of the standard and out through the nozzle. In this position, the pin 21 will be engaged with the stop shoulder or lug 19 as shown in Figure 7, thus limiting the turning of the valve to an open position in one direction. By turning the handle in the other direction, the valve will be closed, the pin 21 engaging the stop shoulder or lug 20 as shown in Figure 12, from the position shown in Figure 7. The plug 12 will be turned from the position shown in Figure 4- to the position shown in Figure 5, when the upper end of the conduit 15 will be closed and the port 1 1 will be brought to an angular position in line with the drain 22, thus permitting the water above the valve to drain from the parts of the hydrant including the chamber 9, pipe 6 and upper portion 1 of the standard so as to prevent freezing.

A. hydrant constructed in accordance with the foregoing description will be free of washers or complicated packing joints, thus eliminating the necessity for constant repairs as well as rendering the device durable and unlikely to get out of working order, and also preventing the parts from leaking.

lVhile I have described my invention'as taking a particular form, it will be understood thatthe various parts of my invention may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

I Iaving thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. A. hydrant including a valve casing having an inlet, an outlet chz-unbena frustoconical valve seat converging downwardly from the outlet chamber and a conduit oitsct from and comniunicating with the inlet and valve seat; a turn plug in the seat provided with parts forming apassage between the conduit and outlet chamber, and means connected with the top or" the plug for turning the plug.

2. A hydrant including a valve casing having an inlet, an outlet chamber, a frustoconical valve seat converging downwardly from the outlet chamber, a conduit ofiset from and communicating with the inlet and valve seat, and a drain port; a turn plug in the seat provided with ports forming a passage between the conduit and outlet chamber when in open position and a passage between the outlet chamber and drain port when in closed position, and means connected wi h the top of the plug for turning the plug.

A hydrant including a valve casing having an inlet: an outlet chamber; a valve seat converging downwardly from the outlet chamber; a conduit offset from and communicating with inlet and valve seat; a turn plug in the seat provided with parts forming a passage between the conduit and the outlet chamber; means for forcing the plug to its seat; and means for turning the plug.

In testimony whereof I have signed my name to this specification.
