SPECIFICATION forming part of Letters Patent No. 513,901, dated January 30, 1894.
' Application filed August 8, 1893. Serial No. 482,259. (No model.)
To all whom it may concern:
Be it known that I, STEPHEN N. EISLER, a citizen of the United States, residingat New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Im-A provements in Rotary Pumps, of which the following is a specification.
This invention has for its object to provide a new and improved apparatus for raising Water or other liquid by the action of a pair of rotary wheels having blades or vanes so relatively arranged that while the wheels revolve in unison in one direction they operate to force the liquid in opposite directions, one wheel forcing the water directly upward therefrom, and the other wheel forcing the water downward into lateral passage ways in which he water rises to the desired point of eleva- To accomplish this object my invention consists in the features of construction andV the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure 1 is a vertical sectional view of a water raising apparatus embodying my invention. Fig. 2 is a horizontal sectional view taken on the line 2&2, Fig. 1. Fig. 3 is a horizontal sectional view takenon the line 3-*3, Fig. 1; and Fig. 4 isa detail vertical sectional view taken on the line 4-4, Fig. 1.
In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein-,-
The numeral 1 indicates an external casing which is square, or similarly shaped in cross section, as will be understood by reference to Figs. 2 and 3. The casing is supported at each corner by an upright or post 5, and to each pair of posts is secured a vertical wall or partition 6one of which is located directly opposite the other, as shown in Fig. 2, for the purpose of forming a central vertical cham ber 7, and two lateral vertical or side chambers 8, which chambers 7 and 8 rise to any desired point of elevation. The lower end portions of thewalls or partitions 6 are rea 5o cessed to provide the ports or passages 9, Figs.
1 and 3, to place the lower end of the central chamber 7 in communication with the lateral or side chambers 8, and the lower end portion of the external casing is provided inopposite sides with lateral inlet ports or orifices 10 and 12 which are respectively located above and below a ixed horizontal diaphragm or partition 13, through which extends a vertical shaft 14 supported at its lower end in a step 15, and adapted to be revolved through the medium of any suitable driving mechanism. As here shown, the' upper end portion of the shaft is provided with a band pulley 16 by which to rotate it, but obviously other mechanical devices for this purpose may be employed. A y
The casing is provided at its lower portion with an inwardly projecting shoulder or ledge 17, arranged beneath the diaphragm or partition 13, and with a similar shoulder or ledge 18, arranged above the diaphragm or partition 13. The lower shoulder or ledge .17 supports the lateral iiange 19 of a metallic circular collar 20, and the upper shoulder or ledge 18 supports the flange 21 of a similar circular metallic collar 22.
In the two collars 20 and 22 are arranged two rotary wheels 23 and 24 having their radial blades or vanes 25 and 26 inclined in reverse directions in such manner that water or other liquid entering the port or orifice 12 is forced downward by the Wheel 23, and water or other liquid entering the port or orifice 10 is forced directly upward by the wheel 24. The water or liquid which is forced downward by the whe'e123 passes laterally through the recesses or ports 9 into the vertical side chambers 8, and by the means described the water or liquid is caused to rise or ascend in the central chamber 7, as well as in the side chambers 8;
The diaphragm or partition 13 is provided at its center with a suitable bearing 27`for the shaft 14, and the upper end portions of the posts 5 are provided with cross pieces 28 and 29 which support bearings 30 and 31 for the shaft, which bearings are located respectively above and below the band pulley 16.
The shaft 14 is provided with lower and upper adjustable collars 32 and 33, adapted to IOO ` for this purpose the base portion of the pump is arranged in the ditch, so that the water therefrom can enter through the ports or passages 12 and 10.
Having thus described my invention, what I claim isl. The combination of a casing containing a vertical chamber 7 having au inlet at its base portion and vertical lateral chambers 8 having inlets at their base portions, a vertical rotary shaft extending through the central chamber, a pair of wheels 23 and 24 fixed to the shaft and arranged one above the other, the upper wheel havingradial blades for forcing liquid upward in the central chamber, and the lower wheel having radial blades for forcing liquid upward through the lateral chambers, and the diaphragm 13 interposed between the two wheels and closing communication between the lower end of the vertical chamber and the lower ends of the lateral chambers, substantially as described.
2. The combination ofa casing having a vertical central chamber 7 provided with an inlet at its base portion and vertical lateral chambers provided with inlets at their base portions, a vertical rotary shaft extending through the central chamber, upper and lower annular collars 20 and 23, two wheels 23 and 24 fixed to the vertical shaft and rotating respectively in the annular collars, and a diaphragm 13 interposed between the two wheels and closing communication between the lower end of the central chamber and the lateral ends of the lateral chambers,substantially as described.
In testimony whereof I have hereunto set my hand in presence ot two subscribing witnesses.
STEPHEN N. EISLER.
