i UNITED STATES PATENT OFFICE.
RALPH GREGORY, OF KANSAS CITY MISSOURI, ASSIGNOR T OIL WELL RECLAMATION COMPANY, 0F CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.
OIL-WELL PUMP.
Specification of Letters Patent.
Patented Oct. 7, 191%).
To all whom 'it muy conrfcm:
lhit known thatv I. lluru (humour, u citizen ot' the United States, residing' at hunsas ('ily. in thc county of Jackson and Stato of Missouri, have invented certain new und useful Improvements in Uil-Tell Pumps, ot' which the following is n specilication. I
,This invention relates to oil well pumps und more especially to what vI tcrm selfecontained pumps for pumping shallow wells, und my object is to produce u simple pump susceptible of use in connection With an oil well pumping apparatus on which tiled epplicntion on Januar)Y 20, 1919, Serial Number 272,152.
To this cud the invention consists in certain novel and useful features of construe tion and organization of ports as hcreinutter described und claimed; und in order that it muy he fully understood, reference is to bc had to the accompanying drawing, in which: v
Figure 1, is a fragmentary vertical section of an oil well pump embodying the invention.
Fig. Q, is a section on the line II-II of Fig. 1.
Fig. 3, is a section on the line III-III of In the said drawing 1 indicates the casing and 2 the cavity at the lower end of said casing, of an oil well.
The pump proper is constructed as follows: 3 indicate sections of tubing connected together by couplings 4 so to form a pump body of stlicient length to extend from or above .the ground level nearly to the bottom of the cavity 2, and secured to and depending from a similar coupling 4 secured to the lowermost. tube section 3 is a valve casing 5, containing a removable valve seat 6 for a bull-valve 7 or equivalent check valve, said seat also form# ing;r an attachment for a depending perforated tube or strainer 8 to exclude particlesk foreign to oil from the valve casing.
9 indicates tubing forming what I term the barrel of the well, and secured to and extendin y from the casing 5 to a point preferablv a ove the oil level in the Well, and said barre] is provided adjacent its lower end with perforations 10 to permit oil to pass from said4 barrel into the body 3- -or fromjhe latter into said barrel. Just above the pcrforations 10 thc hurl-el is provided `with a check valve 11 adapted for opening upward, und at its upper end the barrel is connected by a cou pling,r 12 with a depending pipe 13 adapted to extend u through the top of the wel] for distribution of the oil, and the space between the discharge pipe 13 and the body 3 at a point neer the con plin p 12 is sealed by a coll-.Lr or ring 1 4.
Tie coupling has u perforated dinnietric portion lwhch does not close communica tion between the barrel 9 and discharge pipe 13, but. is for establishing communication be tween the interior of thcbody portion 8, and an air tube 16 extending down intothe well and fastened at its lower end to said con* pling 12.
In opcratimn fiuid under pressure is forced down through tube l so that it, shall lower the level ot' thc oil in thc body portion 3, and hence discharge ull of the oil standing in both the body portion undj the barrel above the level of pcrt'orations 10, because the oil standing in the body portion above the level of seid perforations is forced into the. barrel and upward through the lutter and the discharge pipe 13, the check valve 11 moving upward from its scat to accommodate this operation.
When the pressure of Huid is cut off, the valve 11 reseats and thus retains a charge of oilwithin the barrel and discharge pipe for discharge upon the nentI introduction of fluid under pressure through said tube 16.
lt will heapparent that the oil well described is selfeontained, in that it may be used regardless of the presence oi absence of the well cesingl, that is the pump muy be inserted in a. hole not equipped with a casing.
From the foregoing it will be apparent that I have produced a pump of the character described which possesses all of the features pointed out as desirable, and While I have illustrated and described the preferred construction, if is to be understood that I reserve the right tonnake all changes fallin within the principle of construction am? mode of operation involved and the spirit and scopfe of the appended claims.
I claim:
1. An oil well ump, comprising a tubular br fly, a casing e osing and dependingl from the lower end of saidfbody, a check valve in said casing, 5 tubular barrel within the bod and communicating at its lower end wit said casing abovethe chock vulve, and communicating above the owing with said body, a discharge .pipe in the body, n oou ling uniting the upper 'end of the barrel wit 1 the lower end of the discharge pipe, said aoupling huvingl; n'passngc lending to the inw rior of said iody, and an air iubeexbending down through the dischargc pipe and communicating with the. Suid passage.
2. An oil well puni '1, comprisin n'tubular body, n casing cioslng und spending from thv, Iowvr end of sind body, n chock vulve in said fusing, n tubulin' barrel within the body and ('omuiunicating at ib: lower end with Suid casing ubovie the check waive, und above the casing with said body, n, check valve in the. barrel above the point of communication thereof with said body, L discharge pipe in tho body, a coupling uniting the uper end of the borrel with the iowci end o the dischul e pipo, said coupling hav.. ing a passage lea mg to the interior of said body, 'and nn air tube extending down `through the diSchargo pipe and communicating with the said passa e. In testimony whereof y RALPH GREGORY.
