SPECIFICATION forming part of Letters Patent N 0. 77 6,601, dated. December 6, 1904.
Application filed ay 81.1902. Serial No. 109,644. (No model.)
To (ti/ w/wm/ it may concern:
Be it known that I, FREDERICK J. Kenn- MANN, a citizen of the United States of America, and a resident of Cincinnati, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Air Lift- Pumps, of which the following is a specification.
The object of my invention is an air-lift which will raise and discharge the fluid in a steady stream. This object is attained by the means described in the specification, particu larly pointed out in claims, and illustrated in the accompanying drawings, in which- Figure 1 is a view of an air-lift embodying my invention, the outer jacket and the uptake-pipe being shown in vertical section with their lower ends broken oif and brought together to economize space and the compressedair conveyer being shown in side elevation. Fig. 2 is a vertical central section of the airconveyer upon an enlarged scale. Fig. 3 is a horizontal section of the same, taken upon line '0 u of Fig. 2.
Referring to the parts, the outer jacket A and the. uptake-pipe B extend into the earth to the rock-line. The compressed-air conveyer C is suspended within pipe B below the water-line therein, but at a considerable dis tance above the bottom of the pipe. Air-conveyer C consists of a narrow pipe 0, which leads into an enlarged cylinder 0, which is of an internal diameter greater than pipe 0 and has at its lower end a short pipe c of a diameter equal to the internal diameter of cylinder 0 and having in its walls a series of equallyspaced perforations 0. Pipe 0 is screwthreaded at its lower end into a cone-shaped extension 0", which at its upper end has a screw-threaded neck to engage the bottom of an inverted cup 0, which surrounds pipe 0 The lower end of cylinder 0 is cone-shaped,
and cup 0 flares outward somewhat toward its upper end. The eii'ect of having cylinder 0 of a greater diameter than pipe 0 is twofold. First, the reduced pipe 0 compresses the air, which expands as it passes into cylinder 0' and pipe 0 issuing from the perforation c and being directed by the flared cup and the coneshaped end of the cylinder 0' outward beneath the water above that point, and, second, the reduced portion 0 above the enlarged portion 0 forms a reservoir or chamber within pipe B above the portion 0, so that the air may not escape up along the side ofthe conveyor, but must carry the water upward before it. The cone-shaped end 0 separates the rising column of water gradually, so that it does not come in contact with any direct obstructions which would tend to create a downward suction.
With my construction it is seen that the air is directed upward in the direction of the outflow and that a fresh supply of water is rising continually from the lower end of the uptake-pipe and that therefore the compressed air not only is pushing the water out, but is also assisting in bringing the water in from beneath-that is, it never is moving in a direction contrary either to the outflowing or the incoming water, and that thus a continuous stream of water is maintained at the discharge.
hat I claim is- 1. In an air lift-pump the combination of an uptake-pipe, and an air-conveyor suspended within the pipe below the water-line and above the inlet-opening of the pipe and which consists of a pipe having an air-discharge near its lower end, above the air-discharge an enlarged portion and above the enlarged portion a reduced portion, substantially as shown and described.
2. In an air lift-pump the combination of an uptake-pipe, and an air-conveyer suspended within the pipe below the water-line and above the inlet-opening of the pipe and consisting of a pipe having at its lower end a perforated portion surrounded by an inverted flaring cup above which is an enlarged portion and above the enlarged portion a reduced portion, sub stantially as shown and described.
