Application 'led April 30,

To all whom t may concern.'

Be it known that I, VVAimEN' E. DioxinsoN, a citizen of the United States, reslding in the county of Jackson and State of issouri, have invented certain new and useful Improvements in Well- Cleaning Devices; and I d0 declare the f ol. lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper tains to make and use the same, reference being had to the accompanying drawings, and to the letters and iigures of referencev marked thereon, which form a part of this specification.

' This invention relates to oil well cleaning devices and is primarily intended to effect carried to the earths .tions 2 to thev tube by su the removal of accumulations in the well lining such as is used in connection with soft l sand wells. Oil wells are usually lined withl perforated pipe generally wound with wire, the strands of which bridge the openingsin the pipe so as to provide a foraminous 11ning through which the oil from the s urrounding strata may pass into the casing and discharge at the earths surface. The oil carries with vit considerable sand, shale, paraffin and-asphaltum and after a time the flow is reduced and sometimes stopped because the openings in the pipe to become clogged..

It is the purpose of my invention to relieve the openings of the accumulations and Vin some instances to wash the surrounding strata so that the smaller particles may besurface. and thereby permit the well toagain become active. This I accomplish in an eicient and expeditious manner. In the drawings, Figure I is a vertical longitudinal sectional view throuqh a portion of a well casin to which my mvention is applied.

Ii II is a sectional view on the. line II- I of Fig. I, and

Fig. III is a .sectional view on the line III-III of Fig. I.

ferring 'now to thedrawings by nu-A merals of reference:

slots or openings in` the pipethrough which the'cleaning fluid may pass to'contact with the lining and free-the same of objectionable accumulations. The openings 5 and 6 are ybetween packers which are carried by the pipe and these packers are formed in the following manner:f

VThe upper portion of the pipe is provided with a lixed collar 7 coperating with a movable collar or ring 8 between which and the collar 7 is a compressible andexpansible packing material 9 which may consist of rubber or anyother suitable material adapted for the purpose. on the tube, may move toward and away from the collar 7 but its outward movement is limited by a Xed collar 10, as will be apparentby reference to Fig. I. A collar 11 on the pipe below the openings 6 limits the outward movement of the movable collar 12 corresponding to the one designated 8 in as. thel packer is operated for the upper portion of the pipe.

The lower videdwith a thread 16 to receive a cap 17 from which depends a ported tube 18 having external threads to receive a turbine casing 19 and between the turbine casing a deflector` plate 2O which the threaded portion` 18 be adjusted toward and discharge Openings 2l in the cleaning fluid may be is threaded upon and which may away from the the cap so that deflected against cutting stream or in a relatively broad stream. When the delector plate is adjustf ed to the proper position it ma be secured thereto by a jam nut 22 on t e threaded ltube 18. The turbine'casing 19 is provided with a. rotor 23 which drives a shaft 24 on lwhich a suitable tool 25 issecured. The tool may consist of a shaft 26 having spider The collar-'8, being loose portion "15 of the pipe 1 is .pro-

the lining, either in a thin arms 27 with eccentrically 4mounted ham- I mersor cutters 28, the s eciic construction of the tool and turbine, however, being 'immaterial, the purpose being, as will now be apparent, to accomplish rotation of the knockers 28 and .permit them to come in contact with the linin 29 which is wrapped Il operate against the 'same sopas to remove objectionable accumulem through the openings 5 and 12 to move toward their respective comy plementary collars 7 and 13 and as a result, the packing materials 9 and 14 will be compressed longitudinally 'by expanding laterally-and therefore form efficient packers.

The cleaningfluid which acts against the screen will not only free the same from accumulations but will washout surrounding strata and permit some of the water to pass back into the lining above the upper packer, y

as indicated by the arrows 31, carrying with it the finer particles and freeing the surrounding strata of clogging accumulations. The 'cleaning fluid which passes back through the openings '6 and to the pipe will pass through the lower portion of the pipe and some of it will be .deflected through the openings 21 while the remainder of the stream will act upon the turbine to rotate the tool. The rotation of the tool will cause the knockers to strike against the lining and loosen the tions so that they may be washed out by the water directed against the lining by the deflector plate 20 and b v the water exhausting through the turbine.

It is obvious that various types of tools may7 be utilized by the turbine and indeed this invention contemplates the utilization of cutting, agitating and boring tools now on the market which may be easily fastened to the turbine spindle or shaft; therefore, I do not wish to be type of tool shown.

Attention is also called to the fact that the effective port areas of the openings 5 are greater than the effective port areas of the openings 6; therefore, the entire pipe through the openings 5. Consequently, considerable pressure will be exerted against the packers and the difference in pressure will' insure some of the water passing up through the openings 31, as will be apparent -by reference to F-ig. I.

From the foregoing it will be observed that I haye used the words water and cleaning fluids interchangeably and this has'been done advisedly as any suitable cleaning fluid may be utilized'although water obviously is vthereof, sets of rigid and spaced apart, rubber vpacking sleevesV more solid adhering accumula.-V

limited tothe particular v volume of Water passing through the openings 6 around pipe 1 will have difficulty in rentering thethe most convenient and accessible. When the cleaning has been accomplished, the device may readily be removed from the well ning and the well permitted to resume its ow. What l claim and desire to secure by Letters-Patent is:

1. A well cleaning device comprising a tube provided with a discharge at its lower end, a stopper intermediate the vends of the tube, the walls of the tube having openings above and below the stopper, and packers carried exteriorly of the tube above and .befv

low the openings.

2./A well cleaning tube, packers carried by the exterior of the tube and having laterallyexpansible movement, and a stopper in the tube, the tube being provided with openings between the packers and on opposite vsides of the stopper.

3. A well cleaning device comprising a tube havinga discharge at thelower end thereof, packers carried by the tube having longitudinally compressible and laterally eX- pansible movement, the tube being provided with spaced sets of openings between the packers, and a stopper in the tube between the spaced sets of openings.A

4. A well cleaning device comprising a tube having openings intermediate the ends collars on said tube on the tube between the collars, and sliding metallic collars on the tube adjacent to the openings whereby liuid passing through the openings in the tube will vcreate pressure against the movable metallic collars to eX and the rubber sleeves against the side of the well casing.

5. A well cleaning device comprising a tube, packers on the tube, the tube being provided with discharge ports and rentrance ports between the packers, a ischarge at the lower end of the tube, tor plate below the discharge, low the deflector plate, and tools the turbine spindle.

' 6. In a Well cleaning device, a tube having discharges whereby a cleaning fluid may be discharged into the well lining, a turbine inlet port communicating with the tube, a deflector plate between the turbine and the tube, and a tool carried'by the turbine.

7. In a well cleaning device, a tube having discharges whereby a cleaning fluid may be discharged into the well lining, a turbine inlet port communicating with the tube, a vertically adjustable deflector plate between the turbine and the tube, and a tool carried by the turbine.

In testimony whereof I aHiX my signature.
