UNITED STATES AUGUSTUS D. COOK, 0F LAWRENCEBURG, INDIANA.
PUMP.
Application filed April 6, 1923. Serial No. 630,338.
T0 all whom t may cof/tecra.'
Be it known that I, AUGUSTUS D. Coon, a citizen of the United States, and a resident of Lawrenceburg, in the county of Dearborn and State of Indiana, have invented a new and useful Improvement in Pumps, of which the following is a full, clear, and exact description.
My invention relates to improvements in pumps and it consists infthe combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide a pump which makes use of two plungers that are mounted on a working barrel whereby the pump can pump a larger quantity of water than is capable with the pump which employs b-ut one plunger.
A further object of my invention is to provide a device of the type described which makes use of a novel valve construction, whereby the head of water is not carried `by the plunger which is lifting the water fron'i the well. y
A further object of my invention is to provide a device of the type described which is simple and compact in construction, and which is adapted to be disposed in a well which has a relatively small bore.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings forming a part of this application, in which- Figure 1 is a vertical section through the device, portions thereof being shown in elevation, and
vFigure 2 is a modified form of the device.
1n carrying out my invention I provide a working barrel 1 and a barrel 2, the barrels being secured to each other by a cylindrical casting 3. A piston rod 4 is slidably disposed in the cylinders or barrels 1 and 2 and carries pistons or plungers 5 and 6, the plunger 5 being disposed in `the cylinder 1, and the plunger 6 being disposed 1n the cylinder 2. The plungers 5 and 6 are pro vided with the ordinary packing rings 7 and 6 respectively. Y Y
The plunger 6 on its up stroke is adapted to draw water from the well through a pipe 9 and past a check valve indicated generally The valve 10 is adapted to be closed by means of a spring 11 as soon as the piston ceases to move upwardly. The plunger 5 at the same time is adapted to draw water from the cylinderI 2 into the cylinder 1 as the plunger moves upwardly. lt will be noted from Figure 1 that a cylinder 10 is carried by the casting 3 and is spaced from the cylinder 2. The cylinder 2 has openings 11 which permit the water in the cylinder 2 to flow into the space between the cylinders 2 and 10. The casting 3 has openings 12 therein, these openings also communicating with the space between the cylinders 2 and 10. The plunger 5, on its up stroke, is therefore adapted to draw water from the cylinder 2, through the openings 11, the passageway formed by the cylinders 2 and l0, through the openings 12, and
into the cylinder 1. A check valve, indi-v cated generally at 13, is disposed between the cylinders 1 and 2 and prevents the water in the cylinder 1 from iiowing directly into the cylinder 2.
The plunger 6 on its downward stroke is adapted to draw water from the pipe 9, into the space between the check valve 13 and the top of the plunger 6. An outer cylinder 14 is disposed concentrically about the cylinder 10 and forms a passageway for water. A casting 15 is secured to the sleeve 2 and has openings 16 therein, these openings communicating with the passageway formed by the cylinders 10 and 111. The space between the check valve 13 and the plunger 6 is placed in communication with the water pas sageway formed by the cylinders 10 and 1l by means of nipples 17 which have their ends secured in the casting 3 and the cylinder 10. The plunger 6 on its down stroke will cause the water to flow through the openings 16, the passageway formed by the cylinders 10 and 14, the nipples 17, and into the space between the check valve 13 and the plunger 6. rIhe plunger 5 is provided with a check valve 18 which permits the water to pass by the plunger as the plunger is moved downwardly. i
From the foregoing description of the various parts of the device, the operation thereof may be readily understood. The working barrel containing the two plungers 5 and 6 is secured to the bottom of a tubing 19, this tubing extending from the bottom of the well to the surface of the ground.
The piston rod 4 has a threaded end 2O which is adapted to be secured to the lower end of an actuating rod 21. rl`he rod 21 is adapted to be moved up and down in the direction of its length by any means such as by an the plunger 6. f It will therefore be seen that a double action results from the use of two plungers 5 and 6 which cannot be accomplished by o-ne plunger. The water is caused to move upwardly in the cylinder 1 while the plungers. 5 and 6 are moving downwardly, the water beingV moved by means of the plunger 6 which forces the water from the cylinder. 2 through the openings 11, the space between the cylinders 2 and 10, the openings 12, -and into the cylinder 1. The plungers 5 and 6 on their downward movement in addition to forcing the water that is inthe cylinders 2 and 1 above the plunger 5, also cause the'water to be drawn into the portion ofthe cylinder 2 lying between the check valve 13v andthe Atop of the plunger 6. T he water which is drawn into the -space between the check valve 13 and the plunger 6 passes through `the openings 16, the cylinders 10 and 14, the nipples 17, and into the cylinder 2 as heretofore described. It will therefore be noted from the foregoing that three distinct movements of water take place during the down strolre ofthe plungers 5 and 6. Y
During the up stroke of the plungers 5 and 6, the check valve `18 will close, thereby lifting the water, which has passed above the plunger 5 during the down stroke ofthe plunger, upwardly. rll-he plunger 5 on its Yce upward movement will therefore tend to draw water into the .cylinderi This water is furnished bythe cylinder 2, the water passing through the openings 11, the space lbetween the cylinders 2 and 10, and the openings 12. rl`he plunger 6 on its upward movement will open the check val-ve 10 vand will draw water from the pipe 9 into the cylinder 2. The plunger 6 not only draws water into the cylinder 2 but forces `water which is disposed between the valve 13 and the plunger 6 past the valve 13 and into the cylinder 1. vThe'water will tend to flow past the valve 13 and into the cylinder l in preference tio-.flowing through the nipples 17 and back into the pipe 9 due to the Vfact that a suction is being created in the cylinder 1 by the upward movement .of the .plunger In the yordinary pump only the space directly above the check'valve 10 is filled with water during the upward movement ofthe single however, by using two plungers instead of 1, the cylinder 1 and the cylinder 2 are iilled with water simultaneously. It will therefore be clear from the foregoing statements that by employing two plungers 5 and 6 with the necessary valve mechanism, the pump is adapted to draw a much larger quantity of water from the well than is capable with a pump which employs but a single plunger. As heretofore stated, the device is simple and compact in construction and is not likely to get out of order easily. In Figure 2 I have shown a slightly modilied form of the device. This form is substantially identical to the form disclosed in Figure 1 and corresponding parts of the two devices will therefore be viven the same reference numerals. This form of the device does away with `the outercylindrical casi 14. It will therefore be noted that the de vice is submerged in water so as to permit the water to readily enter the nipples 17. The casting 30 which takes the place of the casting 3 only supports the cylinder 2 and the cylinder 10 instead of supporting the cylinders 2, 10, and 14 as is the case in the preferred form of the device. The plungers 5 and 6 and the check valves 10, 13, and 18 are identical to the plungers and check valves disclosed in the preferred form of the device, and therefore need no further description.
The operation of the modified form of the device is identical with the operation of the preferredV form of the device with the exception that 4the water is drawn directly from the well through the nipples 17 instead of through the pipe 9, openings 16, the passageway formed by the cylinders 10 and 14, and the nipples 17 as is disclosed in the preferred form vof the device.
I claim:

A pump comprising a working barrel, a rod slidably disposed in said barrel, two plungers secured to said rod and being spaced from each other, a check valve carried by said upper plunger, a partition disposed between said plungcrs, a check valve disposed in the bottom of said barrel, a second check valve `disposed in said partition, and a water passageway placing the space between the upper plunger and said partition in communication with the space between th lower plunger and said first named check va ve.
