AIR LIFT-PUMP.
SPECIFICATION forming part of Letters Patent No. 740,999, dated October 6, 1903.
' Application filed November 11, 1902. Serial No. 130,928. (No model.)
0 at whom it may concern:
4 Be it known that 1, JOHN P. COUSE, acitizen of the United States, residing at Glendale, in the county of Los Angeles and State of California, have invented new and useful Improvements in Air Lift-Pumps, of which the following is a specification.
My invention relates to pumps for raising water by compressed air; and the objectthereof is to produce a pump of great efficiency for that purpose. I accomplish that object by the pump described herein and illustrated in the accompanying drawing, which isa View, partly in section and partly in elevation, of my improved pump.
In the drawing, A is the well-casing, within which is the delivery-pipe B, which extends from the extra supply-chamber O to the surface of the ground D. The top of this chamber is tapering, as shown. In the bottom of the extra supply-charnber is an annular fittingE, through which extends a number of ports F, the tops of which form seats for the ball valve-stoppers G. Between the valvestoppers are partitions E, which form a part of the fitting E and keep the valve-stoppers in place. Within this fitting and secured thereto is the pump-chamber H, which extends below the extra supply-chamber and up to nearly the lower end of the delivery-pipe. The lower end of the pumping-chamber is preferably provided with an upwardly-opening valve I. Connected with an air-compressor (not shown) is the compressed-air-supply pipe J, which passes down through the delivery-pipe and into the pumping-chamber, where it terminates a short distance above the lower end thereof in a perforated end J The pumping-chamber and extra supply-chamber and lower end of the'air-pipe are submerged in the water the required depth, which is preferablya little greater than the distance from the normal surface of the water in the well to the discharge-outlet in the pump, and a supply of compressed air is pumped into the pumping chamber and passes up therethrough and out with the water through the delivery-pipe. It will also be observed that the flow of water is started in the pumpingchamber and is augmented by the inflow from the extra supply-chamber while the water is in motion. It will also be observed that the check-valves after the delivery-pipe is filled will keep the same practically full of water and that thereafter the water will commence to flow from the delivery-pipe almost as soon as the air-compressor is started. If desired, the extra supply-chamber could be omitted; but I prefer it, as a greater supply of water can be pumped with it than without its use.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. In an air lift-pump the combination of a delivery-pipe; an extra supply-chamber havinga tapering top attached to the lower end of said delivery-pipe; an annular fitting in the lower end of said supplychamber, said fitting having vertical ports extending therethrough and upwardly-extending partitions intermediate said ports; ball valve-stoppers between said partitions; a pumping-chamber extending through said fitting provided withan upwardly-opening check valve in the bottom thereof.
2. In an air lift-pump the combination of a delivery-pipe; an extra supply-chamber having a tapering top attached to the lower end of said delivery-pipe; an annular fitting in the lower end of said chamber having vertical ports extending therethrough; ball valvestoppers between said partitions; a pumpingohamber extending through said fitting provided with an upwardly-opening check-valve in the bottom thereof. I
In witness that I claim the foregoing I have hereunto subscribed my name this 3d day of November, 1902.
