With the foregoing and other volcijectsmin view which will appear as the description proceeds., theinvention-consists of certain? novel details of construction-and combinationsvof parts, hereinafter more fullydescribed-and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Like characters of reference are used throughout the following specification and the accompanying drawing to designate corresponding parts.
In carrying out the invention, there is provided an improved form of sand separator for use for separating sand from oil being pumped from oil wells making sand.
A combination upset adapter coupling I having a reduced internally threaded upper end 2 will be threaded upon the section of pipe 3 connected with the seat of the sub-surface pump (not shown); The enlarged lower end 4 of the coupling I is externally threaded for threading into the internally threaded upper end of the elongated upper uid chamber 5 composed of a i barrel I 2.
section of predetermined length of pipe 6 and forming the sub-surface pumps intake reservoir for sand-free and filtered fluid.
The externally threaded lower end 1 of the pipe 6 is-adapted to thread into the internally threaded upper end 8 of the adapter coupling 9, which comprises a perforated seat member I0 disposed Within the adapter coupling 9 and a cooperating movable perforated plate I I having a guide stem 35, the coupling 9 operating to cause the pressurized fluid within the production string tubing (not shown), after the sub-surface pump (notshown) has been unseated or lifted from normal operating seating position, to be diverted through the perforations in the perforated mem` ber IlI of the coupling 9 `and through the perforated lower plate 36 into the filter screen section disposed therebelow and now to be described, thus accomplishing a flushing and washing action uponY the sand grains or other foreign matterawhichhaveaccumulated outside the filter element.` -f
The filter element is supported upon a length of smaller pipe I2 which forms an inner barrel filter guide and support which may or may not be perforated, and is threaded as at I3 on its upper end for threading into the coupling 9.
The filter element is formed of a plurality of concentrically disposed wire mesh sleeves I4, and an outer perforated heavy metal sleeve or jacket I5, the same being supported at its upper end by the perforated and grooved top plate I6 and at its bottom end by the solid plate I'I which is centrally bored to extend about the inner The lter element is supported upon the inner barrel I2 by means of the hexagonal jamb nut I8 and locking nut I9 threaded upon the externally threaded end at 2U adjacent its lower end.
An outer jacket 2I is slotted at 22 and is externally threaded at 23 on its upper end for threading into the lower internally threaded end of the adapter coupling 9. The lower end of said outer jacket 2| is externally threaded at 24 on its lower end for receiving and supporting the internally threaded bottom filter support 25 composed of a heavy coupling with welded cross segments 26 extending across its lower end, with an axially disposed threaded opening 21 formed therethrough for receiving the threaded bolt 28 which extends upwardly through the opening 21 and into a threaded opening 29 in the lower end of the inner barrel I2, thus securing the several parts in assembled position. It is obvious that the lter parts may be quickly disassembled for cleaning or replacement of worn parts.
In operation, the fluid passing through plate Il and lower plate 36 washes off sand grains from the lter element without the employing of special fishing tools and additional devices to aid in the accomplishing of bottom hole filter cleaning and washing.
The sub-surface pump (not shown) is unseated and permitsthe fluid column, normally the height of the production string of tubes, to flow downwardly towards the perforated plate l I to be conitrolled thereby as it passes therethrough to effect the cleaning and IWashing of the filter.
While the preferred embodiment of' the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted towithout departure from the spiritof the invention.
What is claimed is:`
