CHARLES ORANNELL, OF OBERLIN, KANSAS, ASSIGNOR OF ONE-HALF TO FLOYD XV. OASTERLINE, OF SAME PLACE.

COMPOUND PUMP.

SPECIFICATION forming part of Letters Patent No. 425,933, dated April 15, 1890.

Application filed December 12, 1889. Serial No. 338,466. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. ORANNELL, a citizen of the United States, residing at Oberlin, in the county of Decatur and State 5 of Kansas, have invented a new and useful Compound Pump, of which the following is a specification.

This invention has relation to compound pumps; and the objects and advantages of the same, together with the novel features thereof, willhereinafter appear, and be particularly pointed out in the claims.

Referring to the drawings, Figure l is avertlcal section of a well provided with a pump 1 constructed in accordance with my invention. Fig. 2 is a perspective view of the pump; Fig. 3, a vertical longitudinal section; Fig. 4c, a transverse section through the pump-cylinder; Fig. 5, a detail in perspective of one of the air-escapes.

Like numerals of reference indicate like parts in all the figures of the drawings.

The hereinafter-described pump is designed to beoperated by any suitable motor, and is especially adapted for use in dry countries for lrrigatin'g purposes, wherein it is desirable to throw continuous, steady, and large streams over the surrounding territory.

Further objects of the invention are to ac- 0 complish the above result with. a pump so constructed as to be capable of production at a reasonable cost, which shall consist of few easily manufactured and assembled parts and which shall be very powerful in its operation and capable of operation with a minimum amount of motive power.

Numerous other objects will appear, and I do not herein wish to limit my invention to the exact arrangement and construction of the details shown, as various changes wholly within the scope and spirit of my invention may be readily practiced by those familiar with this class of invention.

1 represents the pump-stock, which is of any ordinary construction and at its lower end merges into a cylinder2 of considerablygreater diameter than the stock, and from which it is divided by a diaphragm 3,havi-ng a central perforation 4, through which is inserted the pump rod 5, which passes up through the stock. At this point it is properly packed and is provided at its upper end with a small pinion 6. The lower end of the rod passes through an opening 7 in the false bottom 8, located at the lower end of the cylinder 2, and the extremity of said rod takes bearing ina step 9, projecting upwardly from the true bottom 10 of the cylinder, which bottom is provided with a series of feet 11 for elevating the pump above the bottom of the well in which the pump is located, as shown in Fig.1. Between the false and true bottoms of the cylinder there is formed a suctionchamber 13, which chamber, through the opening 7, has direct communication with the cylinder 2, and within the latter cylinder and mounted over the opening 7 and upon the pump-rod,which is rotatable, there is a series of triple-bladed screws 14. The blades of these screws are arranged in a series of three, each radiating from the rodin the form of three spirals arranged equidistant on the rod and extending spirally around the rod from the top to the bottom of the cylinder, so that any water introduced into the suction-chamber will be drawn up into the cylinder 2,wl1en said blades are rotated at a proper speed, and

exhaust the air within the cylinder, and water thus drawn up will be caught by the blades and thrown toward the wall of the cylinder, and consequently through any opening that may be formed therein, and which will be hereinafter described.

At diametrically-opposite sides of the cylinder 2 are located induction-chambers 18, which are each provided with an opening 19, covered by inwardly-opening valves 20. Each of the induction-chambers is also provided with an opening 21 in its bottom, which is covered upon its inside by an internal cham- 9o ber 22, mounted within the induction-chamber, which internal chamber is provided with an opening 23, communicating with the induction-chamber, which is covered by an inwardly-opening valve 24. Passages 25 inclose 5 the openings in the bottoms of the inductionchambers and communicate at diametricallyopposite sides with the suction-chamber in the bottom of the cylinder 2. j

The wall of the cylinder 2 at diamctrically- I00 opposite points and between the two induction-chambers is provided with eduction-ports 26, and communicating with the same and secured to the cylinder are eduction-chambers 27, from each of which there leads an eductionpipe 28, said pipes meeting above the cylinder 2 and merging into a common dischargepipe 29, from which the water is discharged in any suitable manner or conducted to any suitable point from the same. From each of the induction-chambers there leads to the top of the well air-pipes 30, the upper ends of which communicate with independent airpumps 31, designed to be alternately operated.

Any mechanism desired may be employed for rotating the pump-rods and alternately reciprocating the pistons 32 of the pump-cylders, and I will herein describe a simple means for accomplishing the same.

At each side of the curbing of the well there is located a standard 33, provided upon its upper end with a bearing 34, in which there is journaled a transverse shaft 3-5, extending across the pump. A pulley 36, driven by a belt37, leading from any motor, rotates the shaft, and a gear 38, mounted upon the center of the shaft, meshes with and operates the small pinion at the upper end ofthe pump rod. Cranked portions 40 are formed in this power-shaft, the cranks being oppositely disposed, and each is connected to the upper end of one of the pistons of the air-pumps, so that when one piston is upon the downstroke the other piston is upon-the reverse or upstroke, whereby the induction-chambers of the pump will be alternately filled with air in a compressed state. below its pump is provided with a short section or branch pipe 41, which terminates at its outer end in an air-chamber 42, having an opening 43 'at its front normally covered by a gravity swinging valve 45, having a lug 44 projecting outwardly from the front face of the valve through the opening inthe chamber; At each side of the pump-cylinders, upon the power-shaft, I mount ordinary flywheels 46, which while performing their wellknown functions also perform another function, which I will now proceed to describe. Each wheel has its inner face provided with a peripheral cam or flange 47, which flange extends one half the distance around the wheel, and the flange of one wheel occupies a half of its wheel opposite that half of the other wheel occupied by the other flange, so that when the flange of one wheel is in the upper portion of the circumferential path traveled by the same the lower flange is in the lower half of said path. These wheels are so located with relation to the small air-chambers projecting from the air-pipes that when the flanged halves of the same are in the lower portion or half of theircircumferential path the flanges or cams are in contact with the lug or stud upon the gravity-valve, thus pressing the same inward and permitting any air in the induction-chamber with which the Each of the air-pipes air-pipe communicates to escape. It will be apparent, also, that these flanges are arranged in proper relation with the cranked portions of the shaft operating the piston, so that said valves will be operated at the times that the pistons are on their upstroke.

The operation of my invention may be briefly stated as follows: The machinery being started, one of the induction-chambers will be exhausted and water drawn into the same from the well, which water will by a downstroke of the pump-piston connected with this chamber be forced by compressed air into the internal chamber located within the induction-chamber, and by reason of the air thus forced into the induction-chamber the valves will be forced over the opening, and thus prevent an escape of the water back into the well. From the internal chambers the water is forced by the pump down through the passages and into the suction-chamber at the bottom of the cylinder, and it passes up through the opening 7 in the false bottom 8, where it is scooped by the triple-bladed screw, and by the peculiar formation of the same thrown by centrifugal force through the eduction-ports at the sides of the cylinder and into the eduction-chambers, and from thence to the'eduction-pipes, and finally into the discharge-pipe which is common to both eduction-pipes. The operation of the opposite duplicate portion of the pump is exactly the same as just described, only as one set of mechanism is inducing water the opposite set is expelling the same, so that a constant supply of water is passing into the suctionchamber and expelled by the wheel into the eduction chambers and pipes leading therefrom.

Under certain circumstances, as when using the pump inshallow wells, I proposeto dispense with the air-compressing mechanism, as in such case its use is not essential to the working of the pump, but still use the airpipes and leave the opening at the top of the pipes open.

Each of the eduction or discharge chambers 27 communicates with an adjacent inductionchamber through anopening or port 4t}, normally closed by an inwardly-opening valve 49. By this opening air pumped into theinduction-chambers may pass into the eduction or discharge chambers, and thus the water forced through the discharge-pipes.

Certain novel features herein illustrated and described, but not claimed, form a part of the subject-matter of a companion application now pending, filed October 24, 1889, Serial No. 388,018.
