Description
1 E. HUGHES BOOSTER PUMP oct. 27, 1936.
Filed NCW.` 2, 1935 INVENTOR. L 951i@ .Hug/res u r ATTORNEY Patented Cet. 27, 11936 UNITED STATES PATENT OFFICE 1 Claim.
The invention appertains to liquid elevating mechanism and more particularly to pumps for use in oil fields for lifting oil and delivering it to a desired point.
The pump embodies two coacting units disposed the one above the other and connected by a pipe through which the oil, or other liquid, is discharged and through which the pump rod passes, the upper unit being of greater capacity than the lower unit to create and maintain a greater suction to cause oil to flow more freely into the well and insure the lower or regular pump working to predetermined capacity.
While the drawing illustrates a preferred embodiment of the invention, it is to be understood that in adapting the means to meet specific needs and requirements the design may be varied and changes in the minor details of construction may be resorted to within the scope of the invention as claimed without departing from the spirit thereof.
For a full understanding of the invention and the merits thereof, reference is to be had to the following description and the drawing hereto attached, in which:
Figure 1 is a sectional elevation illustrative of a pump embodying the invention.
Figure 2 is a view similar to Figure 1, parts being broken away.
Figure 3 is an enlarged sectional detail of the upper or booster pump unit and well casing.
Figure 4 is a sectional detail on the line 4-4 of Figure 2.
Corresponding and like parts are referred to in the following description and designated in the several views of the drawing by like reference characters.
The numeral I3 designates the usual casing of a deep well and 9 the head. Two pump units are located in the casing and are connected by a pipe I5. The upper pump unit boosts the action of the lower pump unit and comprises a cylinder II and piston I2. The lower pump unit includes a cylinder l1 and a piston I8. The upper unit is of greater capacity than the lower unit and augments the action of the latter to insure its working to maximum capacity. The piston I2 may be of any approved construction and is formed with a central opening 25 which connects with cages 22 and 26 fitted to the piston body. A valve 24 operates within the cage 22 to prevent return of the liquid. An imperforate pipe I5 connects the two cylinders of the pump (Cl. S-194) units and receives the nects the two pistons piston I8 is constructed as the upper piston I2 and functions in a like manner. A foot or stand valve I9 is associated with the lower end of the pipe I5 to prevent return of the oil or other liquid pumped` A check valve 5 coacts with the outlet 8 in a manner well understood.
The pump units may occupy any relative position within the casing I3. The pistons I2 and I8 operate in unison and liquid drawn into the pipe I3 and cylinders II and I'l is retained by the stand valve I9. The lower pump unit functions in the accustomed manne. 'Ihe upper pump unit, being of greater capacity, creates a suction in excess of the lower pump unit which reacts on the sands and slimes of an oil well to cause the oil to flow more freely into the pipe I3, thereby insuring the lower or regular pump working to full capacity. The polish rod l, stuiing box 6, gland 4, fitting 8 and strainer 2l, are well known parts of an oil well. The cylinder II may be closed by heads I0, I 0a or Ib, according to its location. The head I0 is threaded into a flanged ring 28 supported upon an inner shoulder of the head 9. The top side of the flanged ring 28 is beveled and is engaged by screws 29 threaded into the head 9, thereby holding the ring 28 and parts carried thereby in place and comprising a gasket 21 interposed between the shoulder of the head 9 and the flange of the ring 28 so as to provide an air-tight seal for the upper portion of the casing I3,
Having thus described the invention, what I claim is:
A pump structure comprising a well casing, upper and lower pump cylinders located in the casing and in vertical alignment, means providing open communication between said cylinders, the upper cylinder having a discharge outlet, valved pistons in said cylinders and connected together, a foot valve controlling fluid admission to the lower cylinder, means closing and sealing the upper end of the casing, said upper and lower communicating cylinders being imperforate against air admission between the upper piston and the foot valve, and the upper cylinder and piston being of greater capacity than the lower cylinder and piston for creating a suction in the lower portion of the well casing.
