T0 all wwwt it may concern/:- y

Be it known that I, JOSEPH W. BECK, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented new and useful Improvements in Water-Lifting Devices, of which the following is a specification.

My invention relates to the class of pumpingldevices commonly known as air-lifts, devices used in raising water from wells where a current of air under pressure is delivered into the body of water at or near the bottom of the well as a means of lifting a column of Water to the surface by a continuous flow.

The object of the invention is to simplify the means employed for this purpose and provide also a means ofadjusting the dischargeopening to the depth of submergence and quantity of water to be lifted in order to economize the pressure and quantity of air required to lift a given quantity of water to given heights.

To this end my invention consists in the device herein shown and described embodying a discharge-tube perforated at the bottom, an air-pipe extended from the surface or upper end of the said tube'into the body of the water at the bottom of the well, carrying a bell shaped receiver provided with means for engaging frictionally against the sides of the discharge-tube, the air-pipe engaging the bell-shaped receiver by a threaded connection and carrying a valve which by rotation of the air-pipe in said threaded connection regulates the annular orifice through which the air is discharged into the body of the water.

My invention is illustrated in the accompanyin'g drawings, in which- Figure l is a vertical axial section of the well and of the discharge-tube, showing my device applied thereto. Fig. 2 is an axial section of the bell-shaped receiver, showing details of construction; and Fig. 3, a plan View of the bell-shaped receiver sectioned at x x of Fig. l.

Referring now to the drawings, A designates a well or cistern, shown here as a welltube sunk in the ground into the water-bearing stratum indicated. Within the tube or casing A is placed a smaller tube B for lifting l of water, perforated at the bottom for screen-- ing purposes and extending outward beyond the casing A through a suitable cover a. If

desired, the tube B may be provided with a 'shaped receiver is open above by a coneshaped orifice somewhat contracted and entirely open below. It is provided at its lower margin with a plurality of elastic curved fingers d/ to engage frictionally the side of the tube B to prevent rotation of the bell. Within and at the upper part of the conical throat is cast or secured a spider, carrying a central perforated boss d, provided with threads to engage corresponding threads of the pipe C, whereby the bell-shaped receiver D is suspended on said pipe. The pipe C carries above its threaded connection a conical valve c', rigidly secured, which stands in a concentric relation to an outward-daring throat d2 of the bell-shaped receiver D, leaving an annular space havinga like upward flare between the valve c' and the wall of the flaring throat d2. This annular space is narrowed or widened by elevating or depressing the valve c', 'and this is done by revolving the pipe C in its threaded seat in the boss d, the bell D being held from rotation by the lingers d', in frictional contact with the pipe B. The fingers d also retain the mouth of the bell in concentric relation with the pipe B, leaving an enlarged annular space by which water passes upward around the bell.

The mode of operation is as follows: The discharge-pipe ,B, perforated at the bottom, is dropped down within thewell-tube A to the bottom, and within the vpipe B the bell D, suspended by the air-pipe C, is dropped down into the body of water to a submergence of eighteen inches, more or less, below the water-level. Air is then forced downward into the bell D from an air pump or IOO compressor (not shown) as regulated by the cock c2 and by displacement of water as held in compression therein and issuesupward in an annular sheet through the oriiice around the valve C and by impact as well as by lifting force of the air-bubbles lifts the column of Water in the discharge-pipe B and discharges the same in a continuous flow at the cock b.

The action is regulated by the adjustment of the valve C, and this is accomplished by rotating the pipe C in its threaded boss d, so as to reduce the air flow to that required, thus preventing all unnecessary waste of air in raising the desired amount of Water.

I claim as my invention and desire to secure by Letters Patent of the United Statesl. In a Water-lifting device the combination of a discharge-tube open or perforated at the bottom, an air-tube carried downward within the same, and an air-receiver connected therewith, said receiver entirely open below and provided with an annular contracted throat opening upward for discharge of air, substantially as set forth.

2. In a water-lifting device, the combina` tion of a discharge-tube open or perforated at the bottom, an air-tube carried downward within the same, and an enlarged openbottomed air-receiver connected therewith provided with an annular opening provided with an adjustable conical plug or valve for regulating the discharge upward of an annular current of air, substantially as set forth.

3. In a device of the character indicated the combination of an air-pipe, an air-receiver suspended thereon by a threaded connection, elastic fingers carried by the lower end of the receiver, and a conical plug or valve carried on said pipe and adjusted in the relation to the receiver-orifice by rotation of the air-pipe in its threaded connection with the air-chamber, substantially as and for the purpose set forth.

4:. The combination in a device of the character indicated, of the discharge-tube, the air-tube, the air-chamber, suspended upon the same by the threaded connection and having the elastic fingers attached to contact with the walls of the dischargatube, and the conical valve or plug upon the in pipe, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

JOSEPH W. BECK.
