T. WESTGARD PNBUMATIG SPIRAL WATER PUMP sept. 2, 1930.

Filed March 21, 1929 Ver it eXtendsthrough the-apertureV 9 in which it is placed has threaded thereon a locking nut 12 whichv maintains the pipe inset position.

Secured to the lower. end of the compressed v air chamber is ajwater screen Vor cage 13 of the usual type into which the the intake pipe 6 opens;

-In the upper portion of the intake pipe 6, that is, the portion 8 which extends above the upper reducingcoupling 2, there is secured an elongated spiralediin 14 which consists oi a strip .of relativelyy thin metal torsionally` twisted and secured at its edgesto the wall of the -pipein which'itfislplaced.

.. The upper end of the intake pipe 6 is suitjably threaded as indicated atv '15 to facilitate the application thereto of one of a number of pipe sections which make Iupy a wall cashing anduponl the lowerend of which the present ypump isdesigned toV be mounted. A

o The compressed air .line 5l may be provided iwith suitable control' valve such as that'inf dicated at 16 VVso1 that the introduction of air into rthe compressed air chamber may be reg#V ulated at; will.

' f'lfromj the `foregoing description it will be `vfunderstoo'd that'by introducing airunder jv ypressure into the water intake pipe'A section y areduced pressure willfbe createdaboutj the through the upwardly directed.v jets therein,

intake screen, thus causing water surroundy ing' the 'same to enter and pass upwardly through thepipe 6.'- As the column ofwater ascen s through the pipe 6 and the pipe casingr` attached to the upper end thereof, a rotary motion will be imparted thereto by the spiral lin 14, which action will ytend to fiurther increasethereduced air Vpressure or condition of partial vacuum in the lower end 'K of the pipe and cause the; water to pass upwardly faster and smoother. jl o {,While thelength of the spirallin 14 may p be o .fanynumber of inches desired, it is pre- *re'rred thatwhen using ,thesame in a pipe fof two and one-half inches diameter that a three-quarter twister turn bei given thereto v vfor Veach eighteen; inches of length.

, v`while in the foregoing, i have described.

jthespiral-as being secured in the upper end 'ofthe waterintake pipe 6,.it is apparent, of

" course, that if desired this spiral may be made al part of ka separateplpe section or nipple vsuchas that `shown in Figure 4 and indicated by the numeral 17 V/Vhen the spiral .is pro- Y vvided 'inthismannerthe nipple may be 'K ce readily applied or removed `from the upper ,end of the'pipesection 6 and the lower section o f the pipe line to rwhich the pump is attached will then .receive the spiral 18 carried by the' i V'nipple and will be attached to the upper end ofthe nipple as ywill be readily understood.

` .Y Ilclaim:- Y. l I l f 1.y A pneumatic pump comprising a cylindrical body designed to be secured at the lower end of' -lower end of a well pipe line and open for the vintake of fluid thereinto, a plurality of jet Vtubes within and directed upwardly in the body, means for introducing air under pressure to each otsaid )et pipes for discharge therethrough into the body, and spiral means within the upper portion of said body and positioned at lthe lower end thereof between a plurality of jet pipes tor imparting a spiral motion to the uids passing therethrough, said jetr pipes opening through the wall of the `,body and disposed longitudinally and circumferentially 'thereof and discharging air upwardly against said spiral means.

A; pneumatic pump comprising a tubular body open at each 'end and adapted to have one 'end secured to the lower end of a pump line pipe, a plurality of air jet tubes fdisposed-withtherbody at dierent elevations and directed upwardly therein, each of said `jettubes at its lower end opening laterally through the body wall, means for introducing air underv pressure to each of said jet tubes, and'spiralfmeans' within the body and having 'the lower end thereof extended downn wardly of the upper ends of the upper of said jet tubes for imparting a spiral motion to iui'ds passing therethrough said jets discharging Vair upwardly againstA said spiral means. y

,3; 'A pneumatic pump comprising a tubular body open at each end and adapted to have one Vend secured to the lower end of a pump .line pipe, a plurality of air jet tubes l disposedwiththe body at different elevations and directed upwardly therein, spiral means :have one end secured to the lower end of a pump line pipe, a plurality of air jet tubes disposed with the body at different elevations and 'directed upwardly therein, each of said jet tubes at its' lower' end opening laterally through'the bodyjwall, a compressed air casing enclosing that portion of the body having` the jet tubes opening therethrough,

.means for conducting air to the casing, anda .spiral element positioned within the body and lmounted at the lower end thereof between a pair of said jet tubes designed to 1mpart ajwhirling motion to fluids passing therethrough.

' 5. A pneumatic pump comprising a tubular body open at each end and adapted to have one end secured to the lower end of a pump line pipe, a plurality of air jet tubes vdisposed with the body at different elevations and directed upwardly therein, each of saidv jet tubes at its lower end opening laterally through the vbody wallaJ vcompressed jziir casing enclosing that portion of the body having the jet tubesropening therethrough, means for conducting air to the casing, a spiral element positioned within the body designed to impart awhirling action to luidpassing therethrough and mounted at the lower end there- Y of'between the upperof said j et tubes, and Y i' 10 a strainer element carried upon the lower end of the cylindrical body. y In testimony whereof I hereunto ax *my signature.
