tion, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvementin hydrants, the object of the invention being to so construct a hydrant or similar apparatus as to effectually obviate all possibility of the exposed parts becoming frozen and thereby rendered inoperative.

A further object is to so construct a hydrant that the stand-pipe, the valve, and the valve* seat can be disconnected from the main and bodily removed and easily replaced without the necessity of digging.

A further object is to produce a hydrant which shall be simple in construction,in which splashing will be effectually prevented, and which will perform all its functions in an efficacious manner.

With these objects in view the invention consists in certain novel features of construction and combinations and' arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation, partly in section. Fig. 2 is an enlarged view in section of the valve and its connection to the main. Fig. 3 is a cross-sectional view on the line oc @c of Fig. 2.

A represents a water-main provided with a suitable coupling l, and B represents a casing adapted to be planted in the ground and terminate at its lower end in close proximity to the main.

A valve-casing 2, having inlet-ports 3, projects within the coupling 1, so as to receive water from the main, and said valve-casing is provided with external screw-threads 4to mesh with similar threads in the coupling. A tubular plug-valve 5 is disposed within the valve-casing 2 and is provided with ports 6,

vwhich when the valve is turned in one direction will aline with the ports in the valvecasing and permit the water to enter said the end of the valvecasing 2,

`valve. The lower end of the valve is pro vided with a shank 7, which projects through and with a Washer S and a nut 9. The upper end of the valve-casing is slotted, as at I0, whereby to form four shoulders 1l, against which pins 12projecting from the valve, can abut when .the latter is moved to one or the other end of its throw. The valve 5 projects some distance above the upper end of its casing 2, .and its upper end is internally threaded for the reception of the externally-threaded lower end of the stand-pipe 121.

l From its connection with the valve the stand pipe projects upwardly and passes loosely through acap 15, mounted on the casing B. The cap 15 is retained in place by means ot' a set-screw 15.

A spigot or spout 1S is secured to the upper end of the stand-pipe, and the cap 15 of the casing Bis provided with an arm or iiange 19, which projects outwardly under the mouth of the spigot or spout. A iiexible tube 20 is applied to the mouth `ofthe spout or spigot, and the arm or flange 19 is made with a hole 21, through which said tube passes loosely.

From the construction and arrangement of parts above described it will be seen that by turning the stand-pipe the valve will be opened or closed and that as the valve-casing is secured directly to the coupling of the main the water can pass only through the stand-pipe and never around it. There will therefore be no possibility of the parts above the ground becoming frozen, as is the case where the construction is such as to permit the admission of water between moving parts.

When the spigot or spout is turned to open or close the valve, the iiexible tube will move freely in the hole in arm or flange 19 of the cap 15 and splashing will be reduced to a minimum.

When it is desired to remove the valve and its casing for any purpose, this can be readily done by simply turning the stand-pipe until the pins 12 engage two of the shoulders 11 and then continuing to turn the stand-pipe until the valve-Casin g becomes unscrewed from the main-coupling, when the stand-pipe, valvecasing, and valve can be removed bodily.

My improvements are simple in construc IOO tion, cheap to manufacture, and eectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not Wish to limit myself to the precise details herein set forth.

Havin g fully described my invention, What AI claim as new, and desire to secure by Letters Patent, is-

1. The combination with a coupling adapted to be attached to a Water-main and a revoluble stand-pipe provided at its upper end with 4a spout, of a valve-casing adapted to screw into said coupling, a valve revolubly mounted in said casing and communicating with the y stand-pipe, means for rigidly securing said valve and stand-pipe together so that the stand-pipe can be turned inboth directions Without becoming detached from the valve, oppositely-disposed shoulders on the upper end of the valve-casin g and ahorizontally-disposed pin secured to the valve and projecting beyond the same so as to engage said shoulders on the valve-casing When the stand-pipe is turnedbackwardl y for the purpose of removing the valve and its seat from the main and permitting them to be Withdrawnbodily with the stand-pipe.

2. The combination with the spout or spigot, of an arm disposed `under the mouth of said spout or spigot and having a hole therein, and a flexible tube attached to the mouth of the spout or spigot and passing loosely through said arm, substantially as set forth.

3. The combination With a casing, a Water- 'main, a stand-pipe and a valve connected with ing witnesses.
