Specification ofLetters Patent.
Patented Nov. 8, 1921.
Application filed October 30, 1919. Serial No. 334,386.
To @ZZ whom t may concern:
Be it known that 1, JOHN P. T. DAvrs, a citizen of the United States, residing at Elk City, inthe county of Montgomery and State of Kansas, have invented certain new and useful Improvements in Pumps; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to pumps of the class usually employed in oil wells.
rllhe principal object of the invention is to provide an improved pump construction, which when in operation will cause a continuous pumping action with a consequent continuous iiow of the fluid pumped.
Another object of the invention is to provide a pump of this character, the various parts of which are fitted together and connected in such a manner that the pump may be easily assembled or disassembled witpout the aid of specially constructed too s.
A further object of the invention is to provide a pump with a strainer so positioned that sand or other extraneous matter will not find access to the valves..
An additional object of the invention is to provide a pump of this class which will be extremely simple, strong, durable and inexpensive in construction, Vone which will be efficient and reliable in operation, and well adapted to the'purpose for which it is designed.
Vith these and other objects in view, the invention consists of the novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.
1n the accompanying drawings in which similar reference characters designate like parts throughout the several views,
Figure 1 is a side elevation of a pump constructed in accordance with this invention;
Fig. 2 is a longitudinal sectional view through the interior of the pump taken on an enlarged scale;
Fig. 3 is a transverse sectional view taken on the line 3-3 of F ig. 2;
Fig. 11 is a perspective view of the pump cylinder; and
Fig. 5 is a longitudinal sectional view through a modified form of pump.
1n the embodiment illustrated the nu- .the cylinder wall.
The Vblock L is solid, while the block 3 is provided with an axial opening 8 through which extends the rod 9 of a piston 10 which operates within the cylinder 1 between the two blocks 3 and f1. Packing nuts 11 are carried by the block 3 to prevent leakage of any fluid through the opening 8. Upward movement of the piston 10 in the cylinder 1 is limited by means of a sleeve 12 carried by the piston and adapted to engage the block 3. The rod 9 is connected by a coupling 13 to a rod 14 extending through the discharge tube and reciprocated by a pump jack (not shown).
The cylinder 1 is provided at diametrically opposite points and at each end thereof with internally threaded openings 15 and 16, the openings 15 and openings 16 occupying similar circumferential positions upon Connected to the open- 17 and 18, the inlet pipe 17 being disposed at the upper end of the cylinder and being bent downwardly alongside of the same, while the inlet pipe 18 is disposed at the upwardy alongside of the cylinder and then downwardly. The free end of each of these Vpipes 17 and 18 carry inwardly opening valves 19. The discharge tube 5 is provided with an internally threaded opening 2O at a point disposed a slight distance above the block 3 and in longitudinal alinement with the openings 16 of the cylinder 1. The numeral 21 designates a discharge pipe which is disposed on the outside of the cylinder 1 and extends parallel to the same. Carried at the ends and at the intermediate portion of the pipe 21 are outwardly opening valves 22 mounted in suitable casings, which are connected to nipples 23, and these are in turn threaded in the openings 16 and 20 lower end of the cylinder and is first bent to connect the pipe 21 with the cylinder 1 and discharge tube 5 and form communication between the ends of the cylinder with the latter.
In order to prevent sand or extraneous matter from gaining entrance to the working parts of the pump, a perforated strainer casing 241 is fitted around the pipes 17, 18 and 21, and the valves 19 and 22 carried thereby. This casing2/l is formed in two sections having inclined ends, and is clamped in place upon the discharge tube 5 and tubular supporting member 6 by means of clamping-rings 25. Y
Carried by the discharge tube 5 at a point slightly above the upper end of the strainer Vcasing 211 is a spider 26, the arins 27 of which extend iii all directions from the tube 5 Serve to close the major portion of the well hole A and prevent dirt from falling into the portion of the well occupied by the working parts of the pump.
lVhen the rod 14 is reciprocated by the pump jack at the top of the well, the piston 10 will be reciprocated in the cylinder 1. On the upward stroke of the piston the fluid in the well will be drawn through the inlet valve 19 and pipe 18 into the lower end of the cylinder, while any ffluid contained above the piston will be forced through the intermediate valve 22 into the pipe 21 and in turn through upper valve 22 into the discharge tube 5. On the downward stroke of the piston 10 fluid will be drawn through the valve 19 and inlet pipe 17 into the cylinder above the piston 10. while the fluid disposed below the latter will be forced through the Ylowermost valve 22 and through the discharge pipe 21 into the discharge tube 5. It will thus be seen that the pump is double acting and when it is operated a continuous suction will be created and a continuous fiow of the fluid pumped will be effected. Y
In Fig. 5 of the drawings the underlying principles of the pump just described are shown embodied in an air pump-,construction. This airpump consists of a cylinder 28 provided with downturned inlet pipes 29 carrying'valves 30 at their free ends, and a discharge pipe 31 disposed on the outside of the cylinder and extending longitudinally of the same. The discharge pipe 31 communicates with the upper and lower ends of the cylinder and is connected at 'its upper end with a flexible hose 32. The discharge pipe 31 is provided with outlet valves 33. Disposed within the cylinder 28 is a piston 34, the rod 35 of which carries a cross handle 36 at its upper end by which the piston is reciprocated in the cylinder to cause the desired pumping action.
From the foregoing description taken in connection with the accompanying drawings, the construction, use and operation of the invention will be readily understood. 'It
will be seen that the objects of invention have been effectively carried out, as the pump produced is efficient and reliable in operation, and the parts are fitted together and connected with one another in' such a manner that the pump may be easily assembled or disassembled without the use of specially designed tools.
Various changes in form, proportion, and in the minor details of construction may be resorted to without departing from the spirit of the invention as defined in the claims. Y
lllhat is claimed is:
1. A well pump structure embodying a cylinder closed .at its opposite ends, a piston operable in said cylinder, piping connected to the upper end of the latter and extending upwardly to the surface of the ground, valved inlets and outlets adjacent the opposite endsof the cylinder, a pipe connected to and opening up communication between said outlets, an additional valved inlet for the aforesaid piping, and a conduit communieating with the upper outlet and adjacent inlet of said piping serving to carry the liquid from the cylinder into said piping whereby the column of liquid will be supported by the closed end of thecylinder and said piston relieved of excessive weight.
2. A device ofthe class described coinprising a cylinder having internally threaded ends, solid blocks threaded to the end of said cylinder, a discharge'tube threaded to one of said blocks and disposed in longitudinal alinement with said cylinder, a tubular supporting member threaded to the outer block and disposedV in` longitudinal said disi-harge tube, outwardly opening4 valves provided in said discharge pipe at the points where the latter vcommunicate with said cylinder and said discharge tube, a piston operating in said cylinder and having its rod .extending through the block to which said discharge tube is connected and said discharge tube, and a perforated strainer Vcasing surrounding said cylinder, said lpipes and said valves and clamped at its ends tol said discharge tube and said supporting member.
