APPLICATION FILED JAN. 10. 1918.
Patnted Aug. 20, 1918 I 1 all n P BERT A. HARE, OF BRADFORD, PENNSYLVANIA.
OIL-WELL s'rnamn'n.
Specification of Letters Patent.
Application filed. January 10, 1918. Serial No. 211,157.
To all whom it may concern:
Be it known that I, BERT A. HARE, a citizen'of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented Icertain new and useful Improvements in 011- Well Strainers, of which the following is a speclfication.
This invention relatesto improvements in means for applying strainers to the suction apertures of pumping apparatus used in oil wells and the like wherein oil and other liquids are pumped from wells of extended depths.
One of provide a strainer which will the pump cylinder all sand, particles of rock and other abrasive substances, which have a tendency to cut and destroy the plunger, valves and valve seats of the actuating mechanism of the pump, without lessening the volume of the liquid flow to the suction port of the pump necessary to carry out the full functioning of the pumping apparatus.
Another advantage gained by the novel construction and the arrangement of the parts comprising the screening means, re,- sides in positioningthe screen fabric in a pocketed inclosure wholly inside of the periphery of the screen barrel, where it is protected from injurious contact with the side walls of the well.
This forms an important feature in connectionwith pumping wells of considerable depth, where through the reciprocal movement of the pump rods, actuating the pump plunger, there is caused a like movement to the screen barrel of sufficient efiect to cause a chafing away of the screen mesh, when it has a bearing contact with the walls of the well.
Another advantage possessed by my improved device, is that it is provided with means whereby it can be located at any desired point in the line of tubing used in pumping wells, and positioned at any desired distance from the working barrel comprising the oil elevating means.
Other and further objects and advantages of the invention will be hereinafter set forth, and illustrated in the accompanying drawings, wherein: V V
Figure 1, is a side elevation of the strainer barrel. 7
the objects of the invention is to exclude from V Fig. 2, is'a central vertical section through the strainer barrel and the contiguous parts; Fig. 3, is a transverse sectionthrough the strainer barrel. Like numerals of reference denote like parts throughout the several views of the drawings.
Referring tothe drawings, 5 the strainer barrel formed ofany suitable metal, such as cast iron or steel where cheapness of manufacture is desired or of brass, bronze or other non-ferrous metal where a V non-corrosive medium desired. v The barrel 5 is formed with'a conduit or passageway 8 longitudinally thereof, and isv provided with screw threads at each end for the purpose of connecting the same to the working barrel of the pump at the one end, and to the anchor at the other.
Located on opposite sides of the barrel 5 are rectangularly shaped sunken pockets 6., Extending from the bottom ofthe pocket 6 is a rectangularly shaped port 7, communicating with the longitudinal passage 8 Located between the side walls of the pocket 6 andthe port 7, are horizontally disposed ledges 9, extending in rectangular formation around the port 7. Located within the pocket 6, and coveringthe port 7, is a screening medium 10, comprising a wire mesh formed of non-corrosive material. The outer edges of the wire mesh 10, rest upon and are attached to the ledges 9, of the pocket 6, by the compressing frame 11, adapted to reside over the ledges 9 in the pocket 6, and'having an opening adapted to register with the port 7. The frame 11 Patented Aug. 20, 1918.
represents is attached to the ledges 9, by suitable fastenings comprising the screws 12' passing through the frame 11 and the mesh 10 and the gasket 13 is placed between the frame 11 and the wire mesh 10, which effectively closes the passage way to all fluids except through the wire mesh 10. v
It is to be understood that the number ,of
screened apertures in the barrelx5, may be varied according to the requirements; for I generalpurposes the number shownin the drawings will be adequate;
' By the novel arrangement andthe appli-.
cation of the component parts, the screening means, comprising the wire mesh, can easily and quickly be removed for replacement, and due to its location inside of the circumferential line 14, (Fig. 3) of the exterior of the screen barrel 5 it is well protected from.
injury and wear.
It is well understood by those skilled in the art, that it is often desirable to locate the suction ports of an oil well pumping medium, at a given distance from the bottom of the well; it is also desirable to locate the suction ports at a given point below the working barrel of the pumping apparatus, varying according to the conditions of the oil bearing strata through which the well is drilled. To provide for these conditions, varying in difl'erent wells 1 have provided the exteriorly formed thread A on the one end of the screen barrel 5, and the interiorly formed thread B on the other end.
When it is desired to tube a well at the top of the oil bearing strata, or sand, to keep it flooded with oil, a section of tubing is used between the barrel screen 5, and the working barrel, long enough to locate the working barrel at the top of the sand while the screen barrel 5 resides at the bottom of the sand, and to support the screen barrel 5 in proper position, a section of tubing closed at the lower end and known in the art as the anchor, is connected to the screen barrel 5 by the thread A, and extends therefrom to the bottom of the well.
When it is desired to tube a well to the bottom of the sand the screen barrel 5, is connected directly to the Working barrel by the thread A, and the anchor is attached to thread B. The threads A and B, being interchangeable with the threaded connections on the tubing used, the screen barrel 5 can be locatedin any desired place in the tubing in relation to the oil bearing strata through which the well is drilled.
l/Vhat I claim and desire to secure by U. S. Letters Patent is:
1. An oil-Well strainer of the character described, comprising a tubular shell having a plurality of apertures located in the sides thereof, screening means covering said apertures, retaining means covering the edges of the screening means and a compressible medium located between the screening means and the retaining means.
2. An apparatus of the character de scribed, comprising a tubular shell, longitudinally extended pockets located below the outer surface of said shell, apertures extending from said pockets to the inner Wall of said shell, ledges formed in said pockets surrounding said apertures, and screening means resting on said ledges covering said apertures, retaining means for holding said screening means in place, and a compressible medium located between the screening means and the retaining means with means for compressing the same against the screen ing means.
In testimony whereof I have afliXed my signature in the presence of two witnesses.
