PNEUMATIC PUMP.

Specification of Letters Patent.

Patented July ill, 1916.

Application filed April 29, 1915. Serial No. 24,691.

Tn all whom it 'may concern:

Be it known that I, JOSEPH S. HATTERY, a citizen of the United States of America, and a resident of "Waterloo, Blackhawk county, lowa, have invented certain new and useful Improvements in Pneumatic Pumps, of which the following is a specification.

My invention relates to improvements in pneumatically actuated pumps, wherein compressed air is employed to elevate the water column, and the object of my improvement is to supply in such a. device means for directing the entering current of air or fiuid under pressure upwardly and divergingly toward the inner wall of the water conduit so as to more efficiently act in elevating the water supplied to said conduit. This object l have accomplished by the means which are hereinafter described and f' claimed, and which are illustrated in the a-b of Fig. 1. Fig. 3 is a detail perspective view of the sprayer or deflecting device of my said invention.

Similar numerals of reference denote corresponding parts throughout the several views.

My improved device comprises a main casting 1 forming a substantially tubular chamber 16, the latter passing vertically through the casting. The open upper and lower ends of said casting are interiorly threaded, the upper opening 7 to receive the lower end of an upwardly directed conduit or pipe 8 supplied adjacent to said casting with a plurality of small orifices or inletopenings 9. The opening 10 at the lower end of said casting is adapted to receive detachably a depending pipe l1 which is pref erably reduced in diameter a short distance below the casting so that the reduced part may be more easily seated in a drill hole or pit underneath.

The numeral 3 denotes a tubular body located centrally within the chamber 16 with its bore 17 alined with said chamber longitudinally and concentrically and equally spaced from the inner wall of the said chamber, while its open ends are equally spaced away from the open ends of the chamber. The said body 3 is integrally supported within said chamber on one side by means of a relatively narrow vertical web 18, and

on the other side integrally by the wall of a short tubular conduit 19 opening outwardly through the wall of the chamber into an upwardly directed pipe seat or connection 2. The upper part of the body 3 is slopingly coned or expanded upwardly from the point where it receives the conduit 19, while the lower part of the bore 4 of said body is nar rower and cylindrical and provided with threaded parts 5 and 6 at its upper and lower ends.

-The numeral 12 denotes an upwardly coned sprayer-head having a square socket 13 in its top for the introduction of a socketwrench. Said head has an integral depending diminished cylindrical stem 14 terminating in an exteriorly threaded wider part 15, which latter is detachably seated in the upper threaded part 5 of the bore 4 of the body3. The stem of said head is spaced away from the sloping inner wall of the body 3 and is set opposite the horizontal part of the bore of the conduit 19. rlhe conical part 12 extends from the hollow 17 ofthe body 3 upwardly and into the open lower end of the vertical pipe or water conduit 8 a little Way with its upper edge or angular part spaced equally from the inner wall of said conduit.

The parts described when located in a well in the usual way, and the conduit 19-2 placed by means of a pipe or other suitable connection in communication with a supply of fluid under pressure or compressed air at a proper pressure is adapted to elevate water or other liquid received into the upwardly directed conduit 8 through the orifices 9. The compressed air passing into the flaring hollow 17 of the inner tubular body 3, passes upwardly over the inclined surface of the inverted cone 12, which spreads the current and directs it upwardly and obliquely all around against the inner wall of the conduit 8 and underneath the orifices 9. The air in ascending along the wall of said conduit, Sweeps strongly thereover while simultaneously expanding inwardly and thus more completely and efficiently buoys up and drives before it the entering streams of water passing through said inlet. ln case any sand, mud, or other solid matter enters into the conduit 8 through the orifices 9 with the water, such matter may drop between the head 12, the inner body 3, and the inner wall of said chamber 16, to be discharged to the bottom-of the well through the depending pipe 11. Since the diameter of the head 12 is wider than that of the upper end of the body 3, there is thus no interruption to said passage.

Having described my invention, what I Y claim `as new, and desire to secure `by Letters Patent, is:

1. A sprayer-device, for air-lift pumps, comprising an orificed conduit, a chamber i-n communication therewith .and with a supply of air under pressure, and an inverted cone supported within said chamber, spaced from its inner walls and extending toward said .conduit coaXially -within the path of upward movement of air into the conduit, to deflect the air toward the inner wall of the conduit. Y

2. A sprayer-device for air-lift pumps, comprising a conduit in communication with a supply of liquid, and also at a lower level in communication with a supply of flu-id under pressure, and a detlector supported in the conduit between its said communications, and adapted to .deflect the flu-id upwardly toward the wal-ls of the conduit .obliquely and against the liquid in the conduit thereabove.

.sprayer-device dior air-lift pumps, comprising an upwardly directed conduit, a tubular Loriiced chamber below and in communication with t'he lower end of said conduit, a tubular socket supported centrally in said chamber spaced concentrically therefrom and having a communication through the wall of the 'chamber with a source of air under pressure, and a spreader device mounted in said socket vbelow said air-communication, having a contracted stem traversing the socket centrally and an upwardly coned spreader-head .extending above the socket and into the lower end of said oriced conduit, and adapted to deflect air entering from said source of supply upwardly and divergingly toward the inner wall of the conduit below its orilices.

4. A sprayer-device for air-lift pumps, comprising a tubular chamber, a. tubular body supported therein in spacedrelation concentrically, a laterally-directed conduit communicating between the said tubular body and the outside of said chamber, and an upwardly coned sprayer-head with enlarged base seated in detachably and closing the hollow of said tubular body below said lateral conduit, the latter delivering to the space in said tubular body under said sprayer-head, and the top of said sprayerhead being spaced concentrically from the inner wall of said chamber and extending radially beyond the outer limit of the tubular body.

5.-A sprayer-device for air-lift pumps, comprising an upwardly-directed conduit, a tubular chamber in communication with the lower end of the conduit, the lower end of the conduit being perforated immediately above the cham-ber, the lower end of the chamber being provided with engagingmeans adapted to disconnectibly engage the upper end of another alined conduit, said chamber having a cup containing a conical deliectin-g body mounted concentrically therein, and a conduit extending from without into said chamber and said cup below the delecting-body, the said cup being supported within and spaced from the inner wall of said chamber.

Signed a-t Waterloo, Iowa, this 12th day of April, 1915.
