' 12 claires, (C1. 10s-119) l The present invention relates to pumps and,

moreparticularly, to a rotarypumping apparatus particularlyfdesig'ned for pumping from a well.

erating the rotary member of the pump.

Another object'isto provide a rotary pump .in-

cluding novel means for holding: the stationary member of the pump against rotation.

`3A furtherobjectis' to provide adeep well pumping apparatus including novel means cooperating.

withI the well 'casing for holding the stationary meinber'of the pump against rotation.

" lAstill"further object is to provide a well pumpingl apparatus which is so constructed thatits operation will impart an initial velocity to the water to' be pumped. v

`v'Astill further object of the invention is to pro- .;vide fa pumping apparatus which will bestrong and 'rugged in construction but which will besuscep'tible'bf easy and economical manufactureV and readyy installation and adjustment.

Other `objects and features of novelty'vwill bev .apparent from the followingdescription"and drawing, it being expressly understood, however,

that the invention is in noway limited'thereby, or l otherwise than bythe appended claims. 4 Referring to the drawing, in which similar refer- 1 ence characters refer to like parts :v

Hli'gisV a sectional View, takenV on the line 3-3 yit 1haslbeen, in the past, the almost universal practice to employ reciprocating, or jack-type, pumps in deep wellpumping apparatus. Pumps ofthis typeoffer numerous and considerable disadvantages and in 'a'ifew casesrotary type` pumps have vbeen employedfor deep well-pumping,-al

of novel means for eiectingdeep well pumping 'vided a well casing I,'the same constituting a cylindrical casing -sunk into lthe ground Afor any though the practice is not general vnor is the rotary apparatus known to the art suitable for by rota-ry means. l

' According to the present invention there is prodesired' distance asis the usual practice in deep well pumping. Suitable means, such as openings l` 2 may be provided in the casing for the; admission.

of water thereinto, although other means such as an open lower end for the casing may also beprovided for this purpose. Disposed within the casingA and below the water level therein is the rotary pumping device, denoted generally by the ref erence numeral 3.

. The rotary pumping device 3 comprises a cylindrical casing or shell 4, ,the upper and lower vends of which are closed by the closure rings 5, 6, the same being centrally bored to receive lthe shaft 'I which isformed integrally with or rigidly attached tothe vane-carrying member 9 of the pump, the' same being mounted Vconcentrically within the" casing 4. 4Bearing sleeves I0, `II and packing glands I2, I3 may be provided. in the upper and lower rings 5, 5 for guiding and lubricating the shaft 1 andl for preventingthe escape of water from the interior of thepump casingto they suction side ofthe pump around the shaft. A bearing plate may be disposed across the upper, openV end of-bearing I!) in order to provide areaction plate for water discharged from the pump',v whereby it is insured that the vane bearing memberisentirely relieved' fromwater column loading, all such loading vbeing carried bythe rotating cylinder and its ring closure. A discharge por-t I4 is also providedY in the upper closure ring 5 for the delivery of water from the pump.

Mounted on the internal wall of the casing 4,' or integrally formed therewith, is an inwardlyextending wall or abutment I5, the same extend ing the full longitudinal length of the pump casing between the inner faces of closure rings 5, 6- and decreasing in radial thickness from its center in both circumferential directions toward the `internal wall of the pumpk casing. Such wall' or abutment ispreferably` formed in two' identical parts I6, II which, in the embodiment disclosed, are attached' to'thepump casing by screws` I8J I9. and are separated by a packing memberfZ, the same being formed by vfolding a flat `piece o'fpac'king abouta rod 2l which is disposedlongitudinally of the pump casing, the entire packing assembly being disposed' within a longitudinal recess between the'abutment members' I6, I1. A liner 22 may be provided on the internalv wall of the pump casing and such liner yin therotation of. the pump casing.- s

: Mounted in the vane-carrying.- member 9 are ltwo vane members 23; 24 which-extend :the en' casing.

provided on the-vane4 member to-,bearbetween such members and Ithe'innerf face ofzjtheppump.

central, or thickest, portion of the abutment member I5 described hereinbefore. It will, therefore, be apparent that a pumping chamber will be dened between the inner faces of the abutment member I5, the: inner Wall of the lining 22 and the outerperipheryof thevane-carryingmember I9, which chamber will be of uniform radial Width throughout 195 to 200 of its annular extent, and throughout the other 165 to 160 of its annularextent. Willydecrease in` thickness in two directions tovvardftheI point Wherethe packing 20 abuts the outer surface of the vane-carry,- ing member. A plurality of intake ports 8 are formed in the Wall of the pump casing and extend through the abutment member IS. Thedirection of rotation oi the pump casing being clockwise, as indicated by the arrow in Fig. 2 of the drawing, it will be apparent that the intakefports trail the central or enlarged portion of the abutment I5. On the other hand, the exhaust port'I4 is positioned. in the v closure i ring@v 5 closely (adjacent to thepo-int wherethe abutmentnmemberll ,cone tacts the packing` I5.". In practice the {upper} por# tionoi abutment I'I maybe ,cored out adjacent ,the packing I5y and the opening extended in thefdirecftion of travel of the pump an amount suicient to pass the .volumeofwater the pumpgwill throw. The. exhaust port .of .the pump, "therefore, leads the central or enlarged-.portion of abutmentvlf tire longitudinal length-oi the cylindrical member I0' and. whose externalfface's. are formed on; the

be constantly supplied with water. Also, as the casing rotates, the curved Wall of the abutment I7 will act to force the water within the pump casing in a clockwise direction, which movement of the water will be prevented by that one of the vanes which is in open position (vane 23 in Fig. 2) .c The trapped water wi1l,.therefore, be forced through the exhaust port I4 which, as described hereinbefore, is disposed above the reduced portion of the abutment I'I. `Astlfie casing rotates in a vclockwise direction from; its `rposition in Fig. 2, the vane 24 will open and the vane 23 ,willi be closed, whereby when the exhaust port passes vane 23, the vane 24 will cause Water to-beforced through the exhaust port. In this way .the continuous and steady ow of a stream of water through the exhaust port is caused,

there being ynopossibility of an uneven or pulsating stream. y. For each complete rotation of the tween .,whichf the` leading `or closing vane yuncovers lthe,.dischargeiport andthe-'time it p a'SSfs the suction ports.' .h
