' PNEUMATIC EJECTOR-PUMI.
To all whom it may concern Be it known that I, Bmmn'n P..HOPKINS,
I a. citizen of the- United States, residing at (linto'nville, county of VVau-paca, and State of \Viscbnsin, have invented new and useful Improvements in Pneumatic Ejector- Pumps, of whichthe following is a-specification.
My invention relates to improvements in pneumatic ejector pumpsf The object of my invention is to provide a form of construction which can be installed in drive wells, or in any other tu-v bular well, and which can be manufactured at small cost, the number of duced to a minimum.
In the 'dra.w1ngs:--
parts being re Figure 1 is a vertical sectional view of'a' drive well tube-in position for use, and showlng my 1mpr0vede1ector, partly in vert cal section and partly in elevation.
Fig. 2 is a sectional view, drawn on line 2-2 of Fig. 1.
Like parts are identified by the same reference characters throughout both views.
' A is an ordinary drive well tube, provided with the customary drive point B. This tube, l1owever,-is capped at the top withan air tight cap C, through which the vertically disposed water pipe D passes. E is an ordinary shell or pumpinghead. v
Near the lower end of the well tube A, I provide a tubular chamber F, the top. of
' which is provided with a cap plug G into which the lower end of-the water discharge pipe D is screwed, or otherwise-secured. A
duct H extends downwardly through the plug G, and is provided with a double elbow within the chamber F, as indicated at h, h", the other end of this duct H extending upwardly for a' short distanceinto the inlet end or lower end of the tube B, in the form of an upwardly projecting nozzle I. It will be observed that the duct H is therefore substantially a U -sha ed pipe, one end of which. extends through an aperture in the plug G,
and the other end of which constitutes the nozzle I.
At the lower end of the chamber F- it is provided with a valve J, and below this valve the chamber is provided with a piston ring K of rubber, leather, or other suitable packing material adapted to form 'a' waterand air tight joint, -to prevent air from passingdownwardly in the well tube A, around the chamber F and, of course,
' Specification of Letters Patent. Patented I313 16, 1920, Application filed March 24, 1919. Serial No. 2254.796.
' also adapted to prevent water from passing .upwardly in time space.
Belowthe annular packing, and below the chamber F, I preferably provide the well tube A with a. cross rod L, adapted to limit the downward moveinentbf chamber F while allowing said chamber to be lowered into close point B.
Air under pressure is supplied from any suitable source of supply, through a ,duct
proximity to the tapered M, which may enter the well tube A'at any -i-'a'lve J, the water rising ,normally in the pipe D to the level which it naturally assumes in thewell.
Therefore, when the compressed air M is delivered into the well tube, it will eventually pass out through the duct H, and its nozzle I underneath the column of water in the tube D. The water will therefore be blown out of the tube D, and the air will exert an aspiratinglefi'ect, drawing additional water from the chamber F. The chamber 1 will then be constantly refilled by water entering past the valve J, and if the water supply is sufficient, as derived from the strata in which the well is lorated, the ejector may be operated continuously for the delivery of Water through the the upper portion of the chamber.. A' pipe 1 Q may lead from the bottom of this chamber, and constitute the service pipe for supplying water to a building, or'it may be connected with such a service pipe as may be desired.-
By providing a float'valve in this tank, and
utilizing the valve to control deliveries through the pipe D, it is possible to shut off 'water delivery whenever a predetermined water level is reached .in the tank.- A blowoff valve B may be employed to permit air delivery from the tank, and regulate the pressure within the tank. Under these conditions, the air pressure may beconstantly maintained within the well, ,by means of the pipe M, and water delivery controlled entirely by said float operated valve.
I cla1m: 1. The combination with an air tight well tube, of a tubularchamber in the lower portion thereof, in .air tight relation to the well tube, said chamber being provided with a valved water inlet at its lower end, openingupwardly in said chamber, a water outlet duct leading from the upper portion of said chamber, an aspirating (lllCt leading through the top 'wall of said chamber, and provided with a nozzle outlet in the water discharge duct, and means for supplying air under pressure to the well tube above said cha1n= 'ber, whereby the use of a separate air tube may be dispensed with, and the suction developed by the asplratipg diict utilized to draw water into the lower end. of the well tube.
'2. The combination with an air tight well 4 tube, of a tubular chamber in the lower portion thereof. in air tight relation to the well tube. said chamber being provided with a valved water inlet at its lower end. opening upwardly in said chamber, a water outlet duct leading from the upper portion of said chamber, an aspirating duct leading through the top wall of said chamber, and provided with a nozzle outlet in the water discharge duct, a support for said chamber-connected with the lower end portion of the'well tube, and means for supplying air under pressure to the well tube above said chamber, where by the use of a separate air tube may be dispensed with, and'the suction developed by the aspirating duct utilized to draw water into the lower .endof the well tube.
3. The combination with a well tube, of a water discharge tube leading downwardly I therein, an air nozzle in the lower ,end of lowerend thereof, and provided with a valved inlet, van air nozzle leading downwardly through the-top of the water chamher, and having an upwardly projecting outletrportion within the water. discharge tube,
means for supplying air under pressure to the well tube above the water chamber, a"
separating chamber in combination with the discharge end of the water outlet tube, and.
provided with-ablowofi valve for air delivery from vits upper portion, and a service pipe connected with the lower pdrtion of the separating chamber, said separating chamher being located above the well tube, and said water chamber within the well tube being provided with a packing ringadaptedthe well tube below the water chamber, whereby water may be drawn into the well tube and said chamber under nozzle suction at less than atmospher'm pressure.
