AIR-LIFT BUMP To all whom it may concern:

Be it known tnat I, O'r'ro E. HARRIS, a citizen'ol` the United States, residing at Indianapolis, in the county of Marion and State of' Indiana, have invented certain new and useful Improvements in rlndilift Pumps, ol which the following is a specification.

The object of my invention is'to produce a simple,ellicient centgipzzle air lift.

The accompanying drawing, which is an axial section, illustrates my invention.

In the drawings, 10 indicates a base casting having a lower opening 11 and perforations or slots 12 in its walls. Formed in the upper end of casting` lOvis a spider 13 having a central hub 14 threaded to receive a pipe 15 which, at its lower end, is perforated at 16. Surrounding pipe 15 is a casing or pipe 17 which, al its lower end, is mountedin the upper end o'l casting 10 and at its upper end is threaded into a coupling 18. Threaded into the couplirur 1S above the upper end of casing 17, is a partition 19 the center of which` is threaded to receive the upper end of a bell 20, the lower end of which is outwardly flared to the walls ol casing 17 and extended below the upper end of pipe 15 so as to form an annular passage 21, :uljustable by means of thread in coupling 1S to regulate or close annular passage 21'.

Formed in casing 1() is a passage 22 which, at its lower end, is curved upwardlr at the center of casing 10 immediataly above opening 11 thereotband provided with a threaded end adapted to receive a lower threaded end of the nozzle 23 which, at its up er end, is carried above the uppermost pe. oration 16 and flared outwardly, as shown at 24. The outer end of passage also is threaded to receive the lower threaded end of the air supply pipe 24. Threaded into the upper end of cou ling 18 is the water pipe 25 which is extent ed upwardly to .the top of the well. T he entire structure, which has been described, is adapted to be projected downwardly into well casing 26, the external dimensions of the casting 10 being a trifle less than the internal diameter of pipe 26.

In operation the structure is submerved in the water of the well to a desired' dept 1, de-

l pending upon the desired lift, as is custoin ary, and air under pressure forced downwardly through pipe 24. rihis air passing upward through nozzle 28 and out through the flared end 24 rushes u Ward through pipe 15 carrying the column o water therein. with it and at the saine time drawing water upward through openings 11 and 12 into pipe 15, and also drawing water from the lower end of shell 17 through openings 16 into pipe 1.5. As the stream o'i water and air emerges from the upper end of pipe 15 into bell 20 it draws water upward from shell,v 17 through the annular passage 21, and the two streams combine in the bell 2O and pass upward through pipe 25. By actual tests. I have very highly ellioient.

l claim as my invention:

l. An air. lift nozzle struc ture coni rising a central air nozzle having an outward-y flared upper end, and a straight water pipe sur-v rounding said nozzle and having induction openings in its lower end below the discharge end of the air nozzle.

2. An air lilt nozzle structure comprising a upper end and a straight water pine surrounding said nozzle and having in uction openings at its lower end below the discharge end of the air nozzle, a shell surrounding said water pipe, the said water pipe having openingsin its lower wall forming a communication between its interior and the shell below the discharge end ol the air nozzle, and a bell arranged within. said outer shell at the upper end ot' the water pipe and forming an annular suction opening around the upper' end of said water pipe.

3. An air lift nozzle structure comprising a main shell open at its bottom, a tube arranged in said. shell and of smaller diameter than the shell and open at its bottom, a coupling member carried at the upper end of the main shell and adapted to receive the lower end of the water pipe, a bell threaded at its upper end in said coupling member and having a lowerend outwardly anrldawnwardly flared and arranged over the u per end et' 'the inner tube, an air nozzle smaller than the infound the structure herein described to be central air nozzle having an outwardly flared i my hand end seal at Indianapolis, Indiana,
