free rotary movement in the,valve, and is screw threaded at its u per end, which vthreads mesh with interna screw threads in a'sleeve or block 13, the latter screwed into theupper end of the barrel `extension 5, and inclosed by a capk 14 screwed `on t0 the upper end of the extension.

l .A knob or hand hold is secured on the upper end of the stem, and by turning the same, the valve 8 can be raised and lowered to regulate the iiow of water, and it will be observed,particularly by reference to Fig. 4, that the valve is of appreciably smaller diameter than is the pipe, so that when it is elevated above its seat, water will pass around the sides ofthe valve and Will be permitted a free circulation.l

Fig. 2 illustrates my improved hydrant in connection with an ordinary metal casing 16, while Fig. 3 illustrates the device employing an ordinary wooden casing 17. In other respects, the construction is identical with that described in connection with Fig. 1.

Various slight changes might be made in -the general form and arrangement of parts described Without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall withinthe spirit and scope yof the claims.

' Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. In a hydrant, the combination with a barrel, a valve seat, a vertically movable Avalve in said barrel, a stem secured to said valve and projecting up through the barrel, semi-cylindrical guides, curved tongues on the opposite sides of said valve movable in said guides, a drain pipe communicating With said kbarrel-in one of said semicylindrical guides and so positioned as to be closed -by one of said curved tongues when the valve is moved to open position, and be open when `the valve is moved to closed position.

2. In a hydrant, the combination with a barre ,.a valve seat, a vertically movable Yvalve in said barrel, a stem secured to said valve and projecting up through the barrel, semi-cylindrical guides, curved tongues on the oppositesides ofr said valve movable in said guides, a drain pipe communicating with said barrel in one of said semi-cylindrical guides and so positioned as to be closed by one of said curved tongues when the valve To all whom it may concern:

Be it known that I, `Lawis M. LANoAsTER, a citizen of the United States, residing at county of Philadelphia Philadelphia, 1n the and State of Pennsylvania, have invented certain new and useful `Improvements in Hydrants, of which the following is a speci-A iication.

My invention relates toimprovements iny hydrants, the object of the invention being to provide a simple, inexpensive construc-V tion of barrel with improved valve mechan-` ism for closing the lower portion ofthe barrel positioned lbelow the .ground level far enough to prevent freezing, andfor automatically opening an outlet from the barrel` to drain the same when the valve is closed, and for closing said outlet when the valve is o en.

pWith these and other objects in view, the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a broken view partly in elevation, and partly in vertical section illustrating onel form of my improvements. Figs. 2 and 3 are similar views showing the application of my improved hydrant in connection with a metal and a Wooden casing respectively. gig. 4, is a view in section on the line 4-4 of 1 represents the hydrant barrel, whichis an ordinary pipe externally screw threaded at its ends, and connected by a cou ling 2 at' its lower end with the water supplly pi e 3. The upper end of barrel 1 is connected y a coupling 4, with an extension 5, and a spout 6 is screwed into said coupling.

valve seat 7 is rovided in the water pi e 3, and is norma ly closed by a sliding va ve 8, which latter is provided at op osite sides with rounded tongues 9, movagle in semi-cylindrical guides 10 in the pipe 3, so as. to guide the valve in its up .and down movement, and direct the same across a drain pipe 1`1, located above the normal closed-position of the valve, so that when the valve is on its seat, thedrain pipe will be open to drain the barrel, and when the valve is moved to open position, the drain will be closed, as will be readily understood. vThis valve 8 is made with a cylindrical bore to receive the valve stem 12, which latter has is moved to open position, and be open when the valve 1s moved to closed position, a spout on said barrel, a screw threaded bloel 1n said barrel, and screw threads on said stem meshing with said bleek, whereby when said stein is turned the valve will be moved.

3. In a hydrant, the combination with a barrel, a valve seat, a vertically movable valve in said barrel, a stern secured to said valve and projecting up through the barrel, semieylindrieal guides, Curved tongues on the opposite sides oi' said valve movable in said guides, a drain pipe communicating with said barrel in one of said semi-cylindrieal guides and so positioned as to be closed l l l l l by one o'l said curved tongues when the valve is moved to open position. and be opened when the valve is moved to elosed position, a spout on said barrel, a serew threaded bleek in said barrel, and serew threads on said stein meshing with said block, whereby when said stem is turned the valve will be moved7 and a easing inelosing said barrel.
