p Myinvention relates to fan apparatus for use v'in wells .for elevating oil, water, or the like, froml the bottom of a'wel-l'to the surface y l vshowing a still further. modified form,'in

of the ground',` :andfaim's toprovidefa novel and improved device ofthis characterfwhich may be conveniently'- larrangedy ina well *for u efficiently elevatingoil or water therefrom.

' The invention contemplates the'y provision of an inlety pipe leading down into theY well from the surface of thegr'ound'and opening intoa suction or vacuum chamber having an inlet valve leading therein'for permitting the rentrance of-oil-or waterlfroin the well into the chamber, vsaid inlet'pipe'opening intoI the suc#v to-n or vacuum chamber in alignment witha passageway in communication with an outlet pipe leading to the' surface of thef'ground so thatv upon the forcing of water or other liquid down the inlet pipe intothepassageway a suction fwill created in thesuction or vac-` uum chamber which causes the water or oil in the well ftoen'ter the suction or vacuum chamber through thefvalve and be 'carried to the surface of the groundv with the first nien;

'25 .tioned' liquid under'pressure. 'L Y, i

'It is alsdan object of theinventi'onto-'providex an apparatus ofthe above indicated character, which is simple and substantial in construction, Vwhich can lbe manufactured economically, and whichy willloe thoroughly eflicient and practical in use. j y, With the foregoing andotherobjects in view, ywhich will/befapparent'as the descrip'- tion proceeds, the invention residesfin the construction and arrangement of parts, as hereinafter described and claimed, it belngV understoodthat changes canbe made within the scope ofwhatis claimed, without` depart- 40 ing from the spirit of the invention. j

The invention is illustrated inV the raccompanying drawings, wherein: y v 1 Figure 1 isj'a longitudinalsection through my improved apparatus, showing. the upper 5 ends ofthe inlet `and outlet pipes broken away, :uV r Figure 2 is a cro'sssection taken on line 24-2 of Figure 1, f f Y Y Figure 3 is a fragmentary sectional View of a modification of the means of 'communication o f `the inlet pipewith; the outlet pipe in the suction or vacuum chamber, and F lgure 41 is' another fragmentary section which the 'distance between the inlet passageway andthe outlet passageway may'befadf justed for causing greater or less. suction 0I' vacuum in the'suction chamber.

`leferringto the drawings,the numeral 10 designates a relatively large rcasing extending intoa well fromthesurface ofthe ground to e, point below the vlevel-ofliquidinthe V`Wel A i v On the lower end of vthe 'casinglO is threaded, as at 11, armain body 12.`v`v The inainbody `12V- has -arrangedktherein and 'spaced from the Walls thereof a vacuum for suction chamber. 13, Yopening out at lone Side Aof the body 12, as at 14,'saidcha1nber .beingA cylindrical in'shapeand provided atitsinner end with a cylindrical depending Vportion or outlet'15.- Rising from the upper wallofthe suctionchamber above the depending portion o1' outlet 15 isa collar 16 into which is threaded'the lower end of an inlettube 17 extendking'gtothe surface of the ground/andV is Varrangedin the casing 10 adjacent `onehside u thereof. v

lDepending fromvfthe upper wall of the vacuum or suction chamber centrally of the` depending .portion 15 and on a line withthe center-of the collar 16 is a restricted depending sleeve 18, on the lower endof which is threaded a nozzler19, the lopening through whicli is tapered-and restricted, asV at 20.

lThreaded into theupper end' of the Ldepending'sleev'elS atthe center of collar 16 is a tubular member 21 which extends upwardly into thetubel7`and has its upper end closed,

as at 22. This tubular member is of a great deal less size than the tube 17 so that a space is formed aroundthe same for'c'atching and holding scale, thus forminga scale trap, las indicated by the. numeral 23, and inthe upper Apartfof its cylindrical Wall is a series of openings 24 for permitting the entrance of liquid from'the tube 17 into the tubular member4 21.` As the'openings 24 are arranged above the lower portion' of the tubular member 21, it'can thus be seen that scale collected around the tubular member will not enter said openings.

The depending portion or outlet of the vacuum or suction chamber is threaded to receive the upper end of a tubular member 26 the opening through which forms a jet race, enlarged at the upper end, as at 27 to gradually merge into the outlet of the suc tion or vacuum chamber. The member 26 is in alignment with thev nozzle 19 on the depending sleeve 18 soV i that `liquid forced through said nozzle will be directed'into the passageway or jet race. Gn the lowerV end of the main bod-y 12 is threaded or otherwise secured an enlarged cup-shaped bowlY 28 into which the member 26 slightly protrudes, said cup-shaped bowl being in communication with the mainbpening through the bodyv 12 and the main casing` 10. rlhe vacuum or suc- '.ion chamber 13 is internally screw threaded,

as at 29, adjacent the point Vwhere it opens exteriorly oil the body 12 to receive a. flanged collar 30 having an inclined valve seat 31 at its inner 1 end with, an inwardly projecting ,iug`32f at the upper end ofsaid seat and to which is pivoted an .arm` carrying a flap valvef34, adapted -toengage `the seat 31 .for

' normally` closing the vaci'ium or suction CII chamber 13. By inclining the valve-'seat and pivotally connecting the lapper valveV at a point slightly inwardly thereof the weight:

of the iapper valvewill cause the sameto normally bein closed' position. A

F or `stabilizing vthe tube 17 within the casing 10leaf springs ,36 bear against the same at suitable intervals throughout the length of said tube, said springs being riveted to the casing as at 35 with their free ends 37 bearing against the tube, and though I have shown Vbut one stabilizing spring, it is to be under# stood that they are to beprovided throughout the entire length of the casing and tube. Y

.In operation of my improved apparatus, a liquid such as water or oil is forced under pressure 'down the tube 17 from the surface of the ground to the lower end of said tube, and when the liquid reaches thexbottom of the tube 17, it will pass through the openings 24 in the sleeve or tubularinember 21 and thus be forced through the restricted depending sleeve 18 ata relatively high rate of speed, due to the fact that the opening in the sleeve is a great deal smaller than the open ing through the tube 17. The liquid ,entering the sleeve 18 passes through the nozzle 19 and the speed or velocity thereof is increased to a higher rate and is forced into the jet race or opening through the'member v26. As the liquid passes from the nozzle into the jet race, a vacuum or suction is created in the vacuum or suction chamber' 13, thus causing the flap valve v34 to open and oil or water, whichever is contained'inthe well, drawn into the suction or vacuum chamber, vfrom which it Will be carried'with the liquid forced Y forced Y the well.

down through the tube 17 into the cup-shaped bowl 28, communicating with the casing 10.

hus the liquid forced through` the tube 17 and liquid entering through the valve 34 will rise in the casing 10 to the surface of the ground where the same is drawn away. It is to be noted that by arranging the tubular member or sleeve 21 inthe tube 17 that all scale or foreign matter contained in the liquid down through the tube 17 will collect around the Vexterior of'said member 21 and not enter the interior thereof which would 'probably cause clogging ofthe nozzle 19.v It

is to be noted that the nozzle 19 is arranged Vat a point in the vacuum yor suction chamber where all Aliquid Yforced therethrough will be forced directly into the opening or jet'race in themeinber 26, thus preventing such liquid entering thevacuum or suction chamber 13.

Inligure 3 of the drawings, I have shown a modified form of nozzle, wherein I have provided Yan, outwardly flared opening 40 at the discharge end of the nozzle which receives therein a tapered on pointed end 41 of a ypin 42 arranged in themember 26, said pin 42' being'carriedby the lowerend of the member 26 by means of webs, orrthe like, 43. By flaring` the discharge opening of the nozzle 19V and arranging a tapered pin in said opening, the liquid forced through Ythe nozzle will be retained at ahigh rateof speed durin its-short passage in thevacuum or suction chamber, thus causinga greater vacuum or suction in the chamber .for drawing oil or Water into the same from the bottom of f `Inldigure 4 ofthe drawings, I have shown the sleeve 18 as being exteriorly screw threaded through the upper wall of the vacuum or suction chamber so that'the distance or space between the nozzle and the jet race may be, adjusted for increasing or decreasing suction in the chamber 13. In this form of my invention, the tubular member 21 is an integral part of the sleeve 18 so that both of said members are moved upon adjustment of the sleeve. .While I have shown the s leeve'as being threaded foradjustment of the nozzle, it is to be understood that various size nozzles may be usedfor permitting such adjustment and that a nozzle of greater or less length may be threaded into the sleeve 18 shown in Figure 1 ofthe drawings for permitting said adjustment,
