Referring with particu] arlty "tof th'ejdrawing in', the" en'xbodiment of the iliventi'onf therein Shown, A flesign=1testhe tube ofthe improved pump, B deqignates air'supply 1 eans vtherefor, Cy d' stance; -a check va'lii A, D"ilesignates,lin" v for rearranging the Working :fluid to a Avalve `housri-r'iggj 6 in which is 'uppermost Aof the sections a terminatesiii a The air supply means B, .in Figs. 1, 2 and 3, preferably consists of a pipe 9 leading from any suitable supply of compressed air or other working Huid into the wellhole and beneath the surface of the liquid to be pumped Where it enters the' lowermcst tube section a slightly above the check valve 7 as at 10.

Each ot' the check valves C preferably consists of a disk 11 adapted to coact with -a seat l2 one being provided in each valve casing' 5.and ,permitting the rise of iiuids past sucli valve but preventing a return f iow. It will, of course, be understood that any other suitable check valve may be eme bulbous formation above referred to, the

bulbous bubbles impinging on the valve'C breaking up and the air of such bubbles tak` ing on a new forni Which by further ascent is modified b the cone 13 and by being passed over t' e same is again stratified in the column of liquid being pumped as at 15, Fig. 2. The change of form of the air bubbles entrapped in the liquid in the tube is shown in Fig. 2, the air on entering taking the forni of small bubble-s 16 mixed with the liquid, such bubbles later collecting or uniting and forming' stratum as at 17, which stratum prog" essi eiy increases in thickness as atlS and 19 and finally assumes the bulbous form shown at 20, which forni is assumed just before the air would, if not rearranged, break through the column of liq uid in the tube. i

In'the modified form of the invention shown in Fig. 4,`th"e air supply means B comprises, in addition to the pipe 9 which leadsto the lowerniost portion or zone of the-pump,`pipes2 l, V22 and 23, each of such pipes being connected with a tube section a -at a point just aboveone of the valve casings 5 in which is disposed a check valve 11 and a cone 13. The pipes 9, 21', 22 and 23 are provided with controllingr valves 9, 21,

22al and 23El whereby compressed air or otherthe sections of tubing a indel'iendently. By

this arrangement of air suppl., pipes a mine ing 5', by .opening the'v'alve 23 air will bev admitted'to the upper section only andafter the air so admitted has caused the ejection of liquid in suicicnt amount to lower the level in the mine so that the next section will have to be put into operation to further. eject liquid, the valve 23 may bc closed and the valve 22a opened to admit air from the air supply to tlie'next lower section. This pumping of section after section iscontinucd until the Water in the mine is brought to the desired level. It will, of course, be understood that the supply pipe 9 and the pipes 21, 22 and 23 have a common source of air supply and may each beindependently controlled.

The operation, method of use andadvantages of the invention will be readily linderstood from. the foregoing description, taken in connection with the accompanying drawing and the following statement:

(omprcsscd air being admitted at the base of the liquid column in the tube A, such air iii rising through the column Will form in pockets or the like similarto the pockets illustrated in Fig. 2 in the rise of the column of air and liquid in which such air is entralivpef'l. The valve C being interposed in the path of the ascending liquid and air and at the point where the air is about to lose its eiiieiency Withrespect to further propulsion of li uid, the effect of the valve'and the seat on t e passing air and liquid' Will be to destroy the arrangement of the air pocket and liquid, thus-creating a new stage in the operation of the pumpin apparatus, the further rise of the air an Water past the cone 13 iedistribu-ting such air and Wavter so that further upward progress will. be under more favorable conditions than would Jne the case Without rearrangement.

Having thus disclosed 'my invention, I claim and desire t0 secure by Letters Patent: 1. In apparatus of the character disclosed, in combination, a pump tube, means for supplying a Working Huid to the interior of said tube for interniingling With liquid tobe pumped, valves dividing said tube into aA lower section and an upper Section-thus r0- viding aplurality of stages through w ich the liquid being pumped progresses, and means over each valve for re-arranging andi plying working fluid to the tube, and means interposed in tllie path of ascent of the working fluid and fluid to be pumped to break up' 'relative arrangement of Working fluid and Huid to be pumped, and means to rfa-arrange said fluid comprising a member mounted Within and materially restricting the passage through the tube. I

3. In pumping apparatus of the air-lift type, in combination, a tube, means for supplying working fluid to the tube, and means interposed in the path of ascent of the 'Work `andduid to be `further assisting sai working dui www working Hui pumped at the zone of such interpoeed means; said :interposed means including a valve; lthere being4 likewise-means adjacent toV said valve l for reapplying 4said woxgku fluid to the Work of uid being pumped in the lrelative arrangement o its ascent.

`4. In an air-lift pump, in combinatioma tube,l means for suppl ing elastic working fluid to the interior o said'tube andln a `lower zone thereof, means' interposed in the path in a higher zonethan thefzone o supply of said 4working to other Huid to pmnped.

In an air-lift pump, in` combinationl a tube, means for supplying elastic working v2a fluid to the interior of sald tube and in a v lower zone thereof, and means inter osed in the path of ascent of the working uid and in a higher zone than the zone of su ply of eald working iiuid for reaplg'ing sai 'work- 2l mg uidt'o other fluid to pumped; said last named means consisting of an inverted cone.
