To all whom it may concern: I

-Be it known that I, JOSEPH F. JoNEs, Jr., a-citizen of the United States, residing at Bakersfield, in the county of Kern and State of California, have invented new and useful Improvements in Pumps, of which the following is a specification.

This invention relates to a compressed air lift system for pumping Water. or oil, or

water and oil with solids in suspension, from Wells, sumps, pits, etc.

It is one of the objects of the present invention to provide a simple, practical air lift pump with a novel form of air lift mechanism by which the air is discharged into the flow pipe at a plurality of points to effec tively lift a column of liquid; and also to provide means by which a spiral or rifiing motion is imparted to the ascending water and air.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a vertical central section of the well, showing the application of the invention. Fig. 2 is a plan view of the nozzle proper. Fig. 3,is a vertical central section on the line w-w, Fig. 2. Fig. 4-is an end view of the nozzle.

Referring'to the drawings, A indicates the casing of a well and 2 the surface frame from which the flow or discharge pipe 3 is hung. Extending down through the flow pipe to within a short distance of the lower end of same is an air pipe 4, and secured on the end of said pipe is a discharge nozzle casing 5. The upper end of the flow pipe is provided with a T-fitting, as at 6, through one side of which the water is permitted to discharge, and the upper end of said fitting is provided with a plug 7 in which the air pipe is secured.

The air discharge nozzle proper, which is more clearly shown in Figs. 2, 3 and 4, includes an inverted T-shaped casing 5. to which the lower end of the air pipe is connected, as at 8. Positioned on opposite sides of the air pipe 4, and eccentric to pipe 3, are nozzles 9 and 10 connected with an interior air passage 11 in casing 5 and communicating with a suitable source of air supply under pressure through the pipe 4.

The discharge opening 12 in each nozzle is preferably tapered to give the discharging air a greater velocity. If desired, the nozzles 9- 10 may be given an opposite tilt to throw their axes, out of parallelism with the axis of the flow pipe in order to impart a uniform swirling or spiral motion to the column of liquid moved by the device.

In operation, the pressure in the air pipe must be greater than the hydrostatic pres sure of the water at the bottom of the pipe and n quantities sufficient to make the ascendmg column of air and water in the flow plpe lighter in its total height than the we1ght of an equal column of solid Water of the depth of the well from the surface of the Water to the bottom of the pipe. The air discharging through the angularly posit oned eccentric nozzles imparts a spiral motion to the water and also causes the air to become evenly distributed, thereby helping or increasing the lifting efficiency within the flow pipe. The velocity created by the tapered openings in the nozzles is also taken advantage of in this instance as it gives an impact to the water which further aids the lifting efficiency. The spiral motion imparted by the discharging air from the angularly positioned nozzles is of great advantage where more or less solid material, such as sand and grave], is liable to enter the flow pipe, as the spiral motion of the water keeps the solid particles in constant agitation and motion which permits it to be discharged with the ascending or outfiowing column of water.

An air lift designed as here shown is simple in construction and may be easily applied to any standard form of well, as it is only necessary to provide a surface frame by which the flow and air pipes may be suspended.

A suitable form of valve 14 may be pro vided for the purpose of controlling the volume of air admitted to the well and a valve 15 may be provided on the outlet pipe for the purpose of closing same when it is desired to blow back or clear the lowerend or intake of the flow pipe from obstructing materials.

The materials and finish of the several parts of the pump are such as the experience and 'udgment of the manufacturer may dictate. arious changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claim and I do not wish to limit myself to the specific design and construction here shown.

Having thus described my invention, what I claim and desire to secure by Letters Patent is In a compressed air lift pump, the combination with an outer circular flow pipe, of an air pipe concentrically positioned therein and extending to a point adjacent the lower end thereof to provide an annular space between said flow pipe and said air pipe, a T-shaped casing secured on the lower end of said air pipe and having its opposite ends closed, a discharge nozzle projecting at substantially right angles from said casing on diametrically opposite sides of said air pipe substantially midway of said annular.

space, said nozzle being inclined to the vertical and discharging upwardly to produce.
