To all whom it may concern; p

Be it known that 1, Louis on LISSA"BEBG, a citizen of the United States, residing'at Water-town, in the county of'Jefl'erson and State of New York,'have invented certain new and useful Improvements in Hydropneumatic Valves, ,of which the following is a specification. This invention relates to improvements in hydro-pneumatic valves, and has for its ob-I ject to provide a novel, simple and .efi'ective' device of the class, wherein a three-way cock for controlling air or other fluid-pres sure is combined with a water or other liquid discharge or lift; the said features being embodied in a one-part body, which is capable of being attached to a suitable liquid container, for lifting and discharging the liquid under pressure, ior sprinkling or other purposes.

The advantages and features of the invention are fully set forth in the detailed description which follows, .wherein reference is made to the accompanying drawing, in which.. 1

Figure 1 is a top plan view ofmy improved valve. Fig. 2'is'a central vertical section taken on line 2-2 of Fig. 1,showing the valve in the act of lifting and discharging the water from the retainer. Fig.

3 is a similar view; showing the valve in position for exhausting the lifting pressurefrom the retainer. Fig. 4- is a horizontal section, taken on line 44 of Fig. 3.

In the drawing, 2 represents the body 0 my improved valve, which is m onepart,

and which consists of a pressure inlet neck 3, which is preferably internally threaded to receive an air or other fluid-pressure supply pipe 4:, by means of which the pressure is supplied through a ort 5, to a .chamber 6,

in which is dispose a three-way valve 7, i which when operated and set, by a handle 8, in the position shown in Fig. 2, allows the air pressure to ass downwardly through a port 9, for per orming its work. 10 represents a water or other container preferably in the form of a cylindrical tank,- which has a flanged-top 1 1 for supportingv the tank when in use. The top 11 of the container is provided with a .central threaded opening 12to receive 9. depending screwthreaded neck or portion 13 of the body 2.

14 represents an angular port or passage, apart of .WhlCh is disposed in the neck 13 of the'body parallel to the port 9, the lower the top Various means. may beemployed for ad-- mitting the water 19 into the retainer 10, :-to be discharged through the pipe 15 and and3.

ed T Qeive the upper end of afeed-pipe within a short distance of the bottom of, the retainer 10., "The upper extremity.of the port M comprises-.the'hore of a dischar e neckvorfnozzle,16,3yhich isa' part of "t e body 2, and which .alineswith and faces oppositely to, the inlet neck 3. The free end of the nozzle 16 is'preferably tapered. to facilitatethe attaching .of a hose orlike part 17 In carrying out the objects ofmy 1 nvention, the retainer or tank '10 which supports the valve body 2, may be inserted verticallyin another tank, as 18, whichcarries a supply of water or otherfluid 19, the

-tank18being suitably perforated at 20 for receiving the retainer, and the latter is then held in placeby bolts .21 which piercethe end ofl' whichfis eo uI 1 ter.,-boredj and thread- 15, which. is disposed; in, and extends to.

flange of the top 11' and are threaded into.

of the tank 18.

the nozzle 16, but I prefer to use an auto? matic ball-check-valve, which. is inserted in 'a suitable opening in the side, near the botretainer, as shown in Figs. 2.,

tom, of the The check-valve in th e present case consists of a hollow caged-body 22, which has. external threadsfor'screwing into the reand which has a clear longitudinal opening for the passage of the water from the tank 18 into the retainerlO, when'the ball 23 is in the position shown in Fig. 3.

The operation of my hydro-pnemnatic :valve is as follows: Assuming that the valve "7' and the other parts. are in the positions shown in Fig. 3, wherein the water in the retainer 10 and the tank 18 is, at acomm on level, owin to the check-valve being open, to obtain t e water from the retainer for sprinkling or other purposes, the operator shifts the handle 8 from the horizontal positions shown in Figs. 1 and 3, to the vertitainer L1 0, and in which is disposed -a-free---- ball 23. 24:.represents a bushing, which is threaded into the outer end of. the cage 22,

cal position shown in Fig. "2, which partially rotates the valve plug 7 for allowing the 'air. pressure carried by pipe 4 to 7 pass through the said lug, thence downwardly through port 9 into the top of the retainer. When the air enters the retainer, it exerts a sufiicient pressure to force the the nozzle 16. When suflicient water has been forced or lifted out of the retainer, the operator should reverse the handle 8, to the position shown in Fig. 3, which allows the pressure remaining in the retainer above the water to escape or exhaust through the port 9, plug 7 and an exhaust port- 27. Immediately the pressure is exhausted, as described,

the ball 23 will gravitate away from its seat at the end of the bushing 2 1, which will allow the recharging of the retainer through the said bushing.

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

1. A hydro-pneumatic valve, comprising a body having a valve-chamber therein, and having a pressure-inlet and a pressure outletport communicating with said chamber, said body having a liquid-discharge passage,

one portion of said passage disposed parallel to thepressure-outlet port, the other portion of said passage comprising the bore of anozzle, a rotatable three-way valve-plug disposed in said chamber adapted to control the admission, as well as, the exhaust of the pressure, and a handle for operating said valve-plug.

-'2. The combination with a tank for containing liquid, said tank having a threaded opening in its top, of a valve connecting with the opening of the tank, said valve comprising -:a--b ody having apressure inlet port leading to a valve-chamber, and a port leading from said chamber to the tank, said body having a liquid discharge port, one end of said port communicating with said tank, the other end of said port comprising the bore of a nozzle, a three-way valve-plugin said chamber adapted to control the passage of the pressure to and from the said tank, a handle for operating said plug, and

a pipe connected with the liquid discharge port adapted for drawing liquid from the bottom of said tank.

3. In combination, a tank for containing liquid, said tank having a threaded opening in its top and a liquid inlet port near its bottom, a valve, said valve connecting with the opening in the tank, said valve comprising a body having a pressure inlet port leading to a valve chamber and a port leading from said chamber to said tank, said body having a normally open liquid'discha-rge port, one end ofsaid discharge port communicating with the interior of the said tank, the other end of said discharge port passing through a nozzle, a valve-plug in said chamber adapted to control the inflow and the outflow of the pressure to and from saidtank, and a handle for operating said valve-plug.

4t. In a device of the class described, the combination with a liquid tank having a threaded opening in its top, eta valve-body having a depending neck adapted to be screwed into said opening, said body having a valve-chamber connecting with the interior of the tank by means of a port, said body having an air-inlet-port connecting with said chamber, said body having a liquid-discharge passage in the said depending neck parallel to the first port and'communicating with the interior of the tank, said body having a nozzle connecting with said liquid-discharge passage, a pipe connecting with said discharge-passage adapted to draw' the liquid from the bottom of the tank, and a three-way-valve in said chamber, said valve adapted for admitting air pressure to the said tank for forcing the liquld through said pipe and said nozzle, said valve capable of being operated for exhausting the air pressure from saidtank and for stopping the discharge of the liquid through said nozzle, and'means for manually operating said valve.

In testimony whereof I afiix my signature in presence of two witnesses.
