HYDRANT.

Our invention relates to hydrant-sof the general type, which include a valve adapted to be set below the frost line in the ground and means for operating the valve from above the ground. l

' lt is the object of our invention to provide in such a hydrant a novel valve ycasing and valve and lvalve stem structure combined with apipe leading to a discharge pipe and 10 to provide a valve operating means, the parts being-so arranged that the lvalve may be operated above the ground in a simple and effective way. l

One'of the purposes of our invention is to l5 provide a novel valve easing and valve provided with drainage means, such that when the valve is closed, the pipe abo-veit will readily drain, the parts being so arranged that when the valve is opened, thel drainage passages are automatically closed by the valve.

Another object is to provide such a 'structure in which the valve vand stem may be readily drawn out without interfering with the'valve casing. l

Aspecial object of our' invention 1s to provide a valve and valve stem operating mechanism of simple andl efficient structure,

Vwhereby the valve stemmaybe raised and lowered vertically without binding.

' AAnother object in this connection is to provide an operating lever and parts 'so' arranged lthat when the valve is'closed, the parts will be locked in position for maintaining the valve closed. l f

i vention is to provide a very simple structure which affords accurate and easy adjustment of the parts at a point above the ground for insuring the proper seating of the valve.

Withthese and otherobjeets-in view, our invention consists in the construction, arrangement and combination of the various parts of our hydrant,`whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in our claims, and illustrated in the accompanying drawings, in which: Y l

Figure 1 is a side elevationof a hydrant embodying our invention.

YFigure 2 is a vertical,- sectional view 2D through the same.

'Figure 3 is a vertical, sectional lview of the hydrant, showing the parts in a different position from that illustrated in Figure 2.

Figure 4 is a transverse, sectional view Still a further purpose of our presentin- A water supply pipe 14 is illustrated as l connected with the lower end of the valve casing 16 set below the frost line. This valve casing 16 is shown in Figures 1, 2 and 3 and comprises a substantially tubular member having a bore 18 extending longitudinally through it. The lower end of the valve easing 16 is internally screw-threaded as at 20 to receive the end of the supply pipe'14.

The upper end of the easing 16 is internally screw-threaded as at 22 to receive the lower end of the water conducting pipe 24 leading upward throughA theground to thedischarge spout. Y

In the lower part of the valve casing 16 is an annular valve seat 24. A valve 26 of'any suitable material, preferably rubber, is slidably mounted inthe casing 16 in such manner asto coact with the seat 24. The valve 26 is preferably mounted on the lower end of a valve stem or operating ro'd. 28, which extendsr through the valve as shown `in Figure 3. The lower end of the-stem or rod28 is screw-threaded as at 30 and yreceives a small nut 32 below the valve and a nut 34 above the valve, whereby the `valve'is held properly located on the stem. V V

V,The bore 18 is of less diameter than the threaded portions 20 and 22. 'f V On the -interior of the casing 16, we providea plurality ofvertical grooves 36, which extend from the seat 24C upwardly to the threaded portion 22. Thus whenv the valve 26 is raised olf-its seat 241, water may flow from the pipe 14:' past the seat 24e-.and upwardly through the grooves 36. i

yThe casing 16 is provided with a plurality of transverse drainage holes 38 alternating withithe grooves 36 and arranged ina series horizontallyaround the casing at such a height-that when the valvel 26 is seated, it

"clears'the drainage holes 38, but when the valve is raised, it closes these drainage holes.

passage of a substantial volume of water when the valve is unseated.

At the upper end ot the pipe 14 is mount.

ed'a spout fixture, indicated generally at A, having the tubular portion 40 into which the upper end ci the pipe 14 is screwed as at 42 and having the spout 44.

Projecting from the tubular portion 40, preferably on the side opposite the spout, we providea pair of lugs or ears 46. Mounted in the ears 46 is a pin 48 on which is'eccentrically, rotatably mounted a disc 50 having at its ends circumferential rabbets 52.

Formed on the disc is a handle 54.

A pair et parallel arms 56 are provided at their lower ends with annular holes 58 to receive the sides oit the disc 50, whereby the Vas shown in Figure 2. vA rocking arms 56 are rotatably mounted on the disc 50 between the ears 46. Y

The stem or rodl 28 extends upwardly through ahole 60 in the upper part of the tubular portion 40 ot the spout structure A. Above the hole 60 is an enlarged bore 62 to receive packing 64 and a packingnut 66.

On the spout 44 are upwardly extending ears 68. A pin is mounted in the ears 68 and extends between them and a link 72 is pivoted on the pin and extends upwardly the link 72 pivoted as at 76 between its bifurcated arms 78 at one end and has the upper ends of the arms 56 pivoted as at 8O between the arms 82 of its other bifurcated end.

The rocking bar 7 4 has about midway between its ends a vertical bore 84, which has substantially the Jform of a venturi with a relatively contracted waist in the middle and with gradual enlargement of the opening toward both ends.

Received in the opening 84 is a sleeve 85. The stem 28 projects through the sleeve 85 and has a screw-threaded end 86 on which are mounted adjustable nuts 88 and 90'below and above the sleeve.

We .will now explain the practical operation and some of the advantages of vour improved hydrant.

Referring to the valve and valve casing,

it will be noted that weV have provided asingle casing and a single valve, so that this portion of the structure is very .simple and cheap. The one casing is connected at-its ends vwith, the supply and ,discharge pipes. It aiiiords drainage means and a valve seat. A single valve controls the water inlet and the drainage openings. The parts are so arranged that the interior of the yvalve casing and the outlet pipe from the casing are of bar 74 has such relative sizes as to permit the valve to beidrawn from the casing into `the pipe vfor removal, for purposes of repair or forreplacement.

By simply unscrewing. the member 40 from the pipe 24, the spout structure and the valve may be taken oii.

The structurejfoi;operating the valve stem such as to permit ample movement. The

parts are so arranged that the valve stem can move vertically without binding. 'The sleeve prevents any bindingfbetweeni the bar 'Z4 and adjustment ofthose nuts allows :torY adjust mentv of the valve with great accuracy..

The arrangement ofthe eccentric in conf nection with the handle 54 provides for trethe nuts 88 and 90. A very slight n'iendous leverage so that no ditlicultyis incurred inoperating the valve.' VThe mechanism for operating the valve is very simple and inexpensive to make and is easy to install or disasseinble.

Changes maybe mad-e in the details of the construction andA arrangement .of the parts oit our improv-ed hydrant, and it is our intention to cover by our claims any modiiied forms oi structure or use of mechanical equivalents, which may be reasonably in-L eluded within their scope.
