Sept. 18, 1956 H. H. MORGAN WELL PUMPING DEVICES Filed Oct. 14, 1952 iNViiNT OR H H, MOI/91972 ATTORNEYS United States Patent WELL PUMPING DEVICES Hilton H. Morgan, Sarasota, Fla. Application October 14, 1952, Serial No. 314,662

' 2 Claims. (21. 131-409 This invention relates to improvements in well pumping devices of the character used for pumping water out of a well in the ground. and supplying the water to a household pressure system.

When the water in a well contains sulphur or other gases, these are objectionable in the household water system because of the odor thereof and discoloration resulting from the use of such water in the plumbing system, basins, etc. It has been the practice, heretofore, to aerate such water as it is pumped from the well so as to allow the separation and removal of the gases.

The system used for aerating. the water and pumping it from the well to the household pressure system has required the use of two pumps, one of which pumps water from the well into the aerator and asep arate pump to supply the water from the aerator to the pressure system. Such an arrangement, with separate power operated pumps for the respective purposes, not only is expensive to construct and maintain. and operate, but it is ydifiicult to control the relative functions of the pumps, and such .a system does not always. function satisfactorily or automatically. 7 g

One object: in this invention is to overcome the ob jections to well pumpingsystems usedheretoforeas noted above. g

Another object of the invention is to simplify and improve the construction and manner. of operation of well pumping systems of this type to provide for the operation thereof by means of a single pump as distinguished from two pumps used heretofore.

Still "another object of the invention is to improve the manner of controlling the system, both as to the filling of the aerator and as to the supply of water therefrom to the household or pressure system.

According to this invention, a jet is used for drawing the water from the well which is supplied and operated by a column of liquid taken from the household pressure system, and discharges in to the aerator. The water is withdrawn from the latter by the pump and supplied to the pressure system. An electrical control on the pressure side of the jet functions in response to the liquid level in the aerator to withdraw water from the well whenever the aerator becomes low in quantity.

One embodiment of the invention is illustrated in the accompanying drawings in which Fig. 1 is a diagrammatic view of the well pumping system as an illustration of this invention, and Fig. 2 is a detailed sectional view of the jet and controls therefor on somewhat larger scale.

The invention is shown as adapted to supply water to a household water pressure system generally designated by the numeral 1 from a pressure tank 2. This tank 2 contains a body of water maintained under pressure so as to discharge through the line 1 whenever the latteris opened at any valve connected therewith.

Water is supplied to the pressure tank 2 by a pump 3 through a pipe 4 extending from the pump to the tank 2. The pump 3 is shown as operated by an electric 7 2,763,281 Patented. Sept. 18, 19.56

motor 5 supplied with current through wires 6 that are connected with the electric power line 7. The electric current, including the wires 6, is controlled by a pressure switch 8 mounted in a side of the pressure tank 2 and operating automatically in response to the pressure therein. Theswitch 8: is constructed to close the electric' circuit 6 to the motor 5 whenever the pressure falls to the said low point. Most tanks operate on a pressure from twenty to forty pounds, in which event the switch 8 would close the circuit to the motor 5 when the pressure falls to twenty pounds and would open the circuit to stop the operation of the motor and the pump when the pressure in the tank reaches forty pounds. The setting of these pressures maybe varied as desired.

The pump 3 hasa suction line 9 connected therewith and leading into an aerated tank 10', preferably to a point near the bottom of the latter where a foot valve 1'1.is provided. on the lower end of the suction line 9' to permit the withdrawal of water from the aerated tank 10' by the operation of the pump 3. The suction line 9 is shown as extending over the upper 'edge of the tank 10, although it may be connected in any suitable manner therewith as desired.

The aerated tank 10 is shown as a receptacle having an open top on which a cover 12 is supported in upwardly spaced relation from the top of the tank to permit freedom of circulation of air through the upper portion of the latter for aerating the water in the tank and the discharge therefrom of obnoxious gases.

The water is supplied to the tank 10 through a. filler pipe 13.that extends inwardly substantially to the center of the tank and has a down-turned open end over a deflector plate 14 mounted in the tank 10, onto which the water is discharged at a point above the liquid level. in the tank so as to. facilitate the aeration of the water and the discharge of the obnoxious gases therefrom.

The filler pipe 13 extends inwardly from a jet column 15 shown as mounted externally of the tank 10 and having a jet tube 16. mounted therein and extending upwardly in the column 15'. I

The lower end of the jet column. 15 is connected with a well pipe 17 that extends-downwardly in the well to 'a point below the water level therein and usually has a foot valve 18 mounted on the lower end of said pipe 17. Any suitable well structure may be used as desired for supplying water to the pumping system and is not illustrated in detail.

A jet is shown at 19 at the lower end of the jet tube 16 in cooperating relation with the latter to direct a jet fluid upwardly from the jet tube under pressure sufficient to cause a liquid flow through the column 15 and into the filler pipe .13, thereby withdrawing water from the well through the pipe 17. The jet 19 is shown as operated by water pressure, having a water line 20 connected therewith and extending thereto from the main pressure line 1 of the household system.

The flow of water through the line 20 to the jet 19 is controlled by an electrically operated valve 21, such as a solenoid valve, controlled by a switch 2-2 mounted at the upper end of the jet column 15. The switch 22 preferably is controlled by a float 23 in the aerated tank 10 in response to the liquid level in the latter. The valve 21 and switch 22 are shown as connected in an electric power circuit generally indicated at 24 that extends from the power line 7.

The operation of this system will be evident from the foregoing description. After the water system is installed, the aerator must first be filled to the desired water level therein, preferably more than half full, before the operation is started. After the first filling of the aerator, the pump may be primed and the cycle will then function automatically.

The pressure in the tank 2 being below the minimum set point, the switch 8 will be closed, thereby closing the circuit '6 to the motor and operating the latter as Well as the pump 3. The pump 3 withdraws Water through the suction line 9 from the aerator tank 10 and forces it through the pipe 4 into the pressure tank 2, thence to the house line 1. This will continue until the pressure in the tank 2 reaches the maximum set point when the switch 8 will be opened by the pressure in the tank, thereby opening the circuit 6 to the motor and stopping the latter and the pump.

As water is withdrawn from the tank 10, the water level therein will be lowered. This lowering of the water level causes the float 23 to close the switch 22, thereby closing the circuit 24 to the electrically operated valve 21, thus opening the valve. This allows the column of water under pressure in the line to be discharged through the jet .19 into the jet tube 16 in the form of an injector. This injector acts to lift water from the well through the pipe 17 and the injector tube 15, discharging therefrom through the filler pipe 13 into the tank 10. This cycle continues until the float 23 rises sufiiciently to open the switch 22 and thereby closing the valve 21.

So long as the water level in the tank 10 is maintained within the desired range, the injector 15-19 will remain inoperative, but as soon "as the water level lowers su-fficiently, the injector will function to withdraw water from the well into the aerator to maintain a sufiicient quantity therein. This injector functions in response to the pressure built up by the single pump 3 and therefore does not require a separate pump for its operation. The pump operates also automatically in response to the pressure in the tank 2, being turned on or off automatically as the pressure varies within the desired range. This cycle continues to maintain a full supply of aerated water at all times.

The invention has been illustrated and described in one embodiment, although it is realized that variations and changes may be made therein without departing from the invention as set forth in the claims.
