AIR PUMP.

Application lcd October 23, 1923.

My invention relates to air pumps of the type adapted to be put int-o Wells for the purpose of forcing` liquid from the Well to a place of delivery above the surface, and it has among its salient objects: to provide a device adapted to be placed down in a Well to any desired depth to receive the liquid to be lifted, with an air-pressure operated valve or gate to control the inlet of the liquid thereto, and with air pressure for forcing said liquid from said device through a discharge pipe to the surface, said air pressure being controlled at the surface; to provide in a device of the character referred to, airoperated kvalve members located down in the W ll and cont-rolled from the surface through the medium of compressed air; to provide a a simple andvpra-ctical, self-contained device ofthe character' referred to and to which air pipes and dischargepipe' for the liquid can be attached as it is placed down in the Well, thus providing a device which can be removed bodily from the well for adjustments or repairs; and, in general, to provide an improved means and method for forcing water, oil, or other liquid from a Well by means of air under pressure. e

In order to explain my invention, I have illustrated one practical embodiment thereof on the accompanying sheet of drawings, in Which,

` Figure 1 is a vertical sectional view showing a Well casing With my device. in place therein, all shown in section and with parts broken out to reduce the length of the view:

Figure 2 is a cross sectional view taken on line 2 2 of Fig. 1,'

Figure 4 is a cross sectional view taken on line 4 4 of Fig. 1;

Figure 5 is a vertical sectional view taken on line 5 of Fig. 3;

Figure G is a vertical sectional view taken on line 6 6 of Fig. 3;

Figure isa vertical sectional view taken on line 7 7 of Fig. 3; and

Figure 8 is a perspective view of an air moved valve member.

Referring now in detail to lthe drawings, the invention as here embodied for disc-riptive purposes, comprises a Well casing, 10, in which isY placed a cylindrical member 11. elosed at its bottom and provided with inlet Serial No. 670,248.

openings 11` through its side, said cylinder having secured in its upper end three cylindrical members, as 12, 18 and 14, fitted closely together i'latwise, substantially as shown, the middle member 13 having a central bore, a's 13a, which extends partly into the member 12, as at 12a, and partly into the member 14, as at 14, constituting a cylinder Within which is mounted a piston, 15, having a piston rod, 16, attached to a cylindrical gate, 17, by means of a spider member-18. Said gate` is also provided with inlet openings, 17a, adapted to register With the inlet openings 11 when said cylindrical gate is in one position, as shown in the drawings, and to close said inlet openings 11 when said cylindrical gate or valve is moved. An outlet or discharge pipe, 19, is provided which is` screwed into an opening 12b in the member 12, said pipe extending down into the cylindrical member 11 and cylindrical gate 17, through thespider 18, as shown, and being provided with an inlet check valve, 20, at itsA lower end, substantially as shown. The members 12, 13 and 15, also have holes therethrough, as 12b, 13b and 14, forming a lcontinuation of said pipe, 19, with a pipe cxtension 192L screwed into the opening 14b in the upper member 14, as illustrated, said discharge pipe, it being understood, can be extended to any desired place of discharge.

An air supply pipe, 21,V is extended doivn into said Well and connected at its lou'er end tO an opening 14Crin the member 14, and a second air supply pipe, 22, is extended down into said Well and connected at its lower end to an opening, 14d, back of the opening, 14J in Fig. 1, but seen in 7. rFliese- air supply pipes 21 and 22 are connected by means of a valve structure, 23, with valve, 24, tl erein, with a single air supply pipe, 25, from any suitable source of air supply. The valveY 24,.can b eoperated 1n any desired manneiz/ for alternately connecting the pipes .21 and 22 with the one supply pipe 25, as Will be clear from the showing. 1 have shown no special means of operating the valve 24, as this can `be Amechanically operated, or other- Wise to alternately supply'air under pressure through the pipes 21 and 22. A

The block member 13, has formed therein a semi-,circularvalve chamber 13, `in which is slidablyl mounted a correspondingly shaped valve member Qfrbwns at 011e en@ Civ and at the lower side thereof, an extension 2li, to cover and uncover the hole i2 when moved to one end ot the valve chamber i3, said valve el amber being slightly enlarged or cut out around the bottom thereof to provide space to receive a lip ilange QG", around the lower tace et the valve member 2G. It will be understood that the hole lll-d, the 7alve chamber llc and the hole l2, together form a continuation passageway from the air supply pipe 22, 'tor the supply o't air under pressure through said blocks l2, 13 and l-ilv, to the c vlinder 1l, when aid valve member QG is moved to the ri eht. This will be understood `troni Fie'. 'i'. the valve 26 being;` in section. rlhe opposite ends of said valve member 3G are out away slightly. as at 26. to provide sul'lieient space around the end of said valve member when moved to its stop position to admit air Ator the initial movenient of said valve member i'rom one end oil the valve chamber to the other end thereof. The valve member 26 is moved 'trom one end to the other by air pressure admit-ted first to one end ot the chamber 13C and then to the other end thereof, from the pipes 21 and 22,

Said valve member 26 has a vertical port, QG, therethrough. with an extension` as 26h, Fie. 8, to one sido thereofA lin the top tace of the valve member. and with a similar ere tension. 2G". to one side thereoil in the inner laee ot said valve member, ttor a purpose hereinatte airain referred to. Then in the position indicated in Figs. 2, 3 and t3, said vertical port QG in the valve member 2G registers with a port. lle. in the head block 1l. and also. at its lower end. with a port, 12C. in head bloeit lf2. while the lower extension. Q61, communicates through passageiavs 13 and l2". with the lower end of the piston cylinder, at l2?. under the piston 15, as seen in Fie'. G. lllhen said valve member $26 is moved to the rigg'ht. said vertical port :EGW at its upper end, continues to be in rommunication with the port ist". in the head bloelt H. bv means o l1 its extension 2G, lt will be seen that when in the position shown in Fie. (l. exhaust 'from the piston cylinder and also l'roin the receiving cylinder 11. is open at the. same time.

le'lerrhur aeaiu to Figs. 3 and 7. another port lill isi-formed in the side of' said head bloeh lil. at the side of the valve chai'nber L39. This port is closed when the valve member 26 is in its lett hand position. as shown. but is adapted to be opened b v the. initial movement ot said valve member 2G to the rieht. as will be understood :trom

Fifi. This initial movement of said valve member 2th however. tirst closes a` similar port 13S. Figs. 3 and 5, which leads to the upper end ot the piston cylinder through port 14g in head block 1,4. These ports 13S and les admitted the air to the piston cylin- Lesser? der to :i'oree the piston l5 downnulrdly to open the cylindrical grate 17, as shown in Fie'. l, when the valve member 2G was moved to its shown position.

The use and operation ot my invention ma)v be briel'iy stated as follows:

lVhen the valve 2st, which controls the admission of air under pressure from the pipe 'as turned to the position shown and air was admitted to pipe 21, the valve member 2G. at that time to the right hand end o'l the valve chamber 13C, was moved to its shown position. the air entering' in the eut-out portion 2G suli'cieutlv to initially start said valve member to the lett and then forcing' it all the way to the opposite end oli said valve chamber 13". This opened ports 13g, from the valve chamber, l5, and 1&5, admittinglv air under infessure from supply pipe 2l, to the top ot the. piston cylinder. at. 14:", and forcingsaid pistou downwardly and openingl the cylindrical egale i7 tor the adu mission o'li liquid to the cylinder 1l. It also opened the ports lite, 26d. QG and 152, and 120, as shown in Fig. G, to permit ew haust from the lower end ofthe piston cylinder 12, as said piston l5 moved downwardly, and to permit exhaust from the main cilinder 1l, as the liquid rises therein through the ports l1 and 17, ilirom the well casing 10. Thus air 'l'rom supplj7 pipe 2l, operates only to move the valve member lo lo the lett` whereby exhaust is established `trom the lower end o the piston cylinder and `trom the receiving;l cylinder, and air is supplied to the top ot the piston cylinder to move the piston l5 dowi'iwardly and open the main inlets 1l and 1T. Now when the, valve Qi, is turned to direct air -from pipe 25 to pipe 2Q, the following' things are accomplished in the order named: initial movement ot valve member Q6 to the, right; closing' ol port lijf; opening' of port 1.3i to admit air to the lower end` ol the piston evlinden as 1212 Fig. 7. to raise the pistou and close the main cylindrical `:rate il; movim; the port extension 2t? in the valve moinber E2G to register with the port loi Fig. 3, giving exhaust trom the upper end ot the piston cylinder. 14;. File'. 5; said exhaust beine' through the vertical port 26d in valve Q6. its e.\;lcnsion 2G, and the port lll" in head block lai. 'The final movenient ol the valve member 2o. moves its tootA extension 26 trom over opening;- lil@ and thus admits the full suppl)v et air from pipe 22, through nassae'ewavs leid. valve fhamber 13C (lett hand end thereot), passageway l2, to the top of the receiving cylinder l1. and forcing,` the contents therefrom through the cheek valve 20 and out through the discharge pipe 1.9 and 19a, as will be understood :trom F l..

Thus with a very simple and practical apparatus, I am able with air under pressure to manipulate the control valves and control the admission of liquid to a receiving cylinder down in a well, and to force it therefrom to the surface, and While I have shown but one embodiment of the invention, I am aware that changes in details can be made ywithout departing from the spirit thereof, and I do not limit the invention to this showing, except as I may be limited by the hereto appended claims.
