In etail, the construction here illustrated is as follows:--
I employ a comparatively short'section of tubing 1, having a screw-thread 2 at'its upper end, adapted .for the attachment of an internally, screw-threaded head 3. The lowerendof saidtubing 1 is provided with a comparatively long screwthread 4, for the so reception of an' internallysorew-threaded A s expansive, pacln'ng member, consisting preferabl of-a rubber sleeve 6 is placed between the ower end othead 3 and the upper face of the compression member 5..

pinching sleeve 6, which sleeve '2 is longitu ally movable upon the tubing. Between themner wall o t-said sleeve 7 and the periphe of the tubing, there is an annular space the object of which will be presently set forth. The upper end of sleeve 7 progegs through the packing sleeve 6 and enan annular chamber 9 in the head 3, in which said sleeve is adapted to have a free longitudinal or vertical movement. Comression member 5 is internall tion of the lower screw-threaded end 4 of t tubing nipple 1. The flexible, expansive sleeve 6 is compressed longitudinally and caused to expand laterally or circumferentially, as shown in Fig. 2, by screwing said tubing-nipple 1 downward through said compression member 5;
It is necessary to construct the packer so that sleeve 6 may be expanded after it islowered into place inside the casing in the well, and in order to be able to do this, I provide means for locking member 5 in the casing so that it cannot revolve, then when the tubing, which extends to the. surface of the ground, is turned, nipple 1 is caused to travel downward through the threaded member 5, thus compressing sleeve 6 long I tudinally and laterally expanding the scum as aforesaid. The tubing 'which extends from the packer u ward to the surface of the ground is indie ted at 10. Tubing 10" is also extended downward from the mama The yleans for locking member 5 within the casin is as follows: The lower end of said member 5 is provided witlnon eroentrie extension or hub 11, upon which an ecceu trio. ring 12 is loosely mofintediand retained in position by means 0 a collar 13, which is secured to hub 11 by means of the fillis tor-head screws 14. .R1 12 is free to turn upon hub 11,. and b givmgthe tubing and the thereto attach movement, said ring is caused to turn upon said hub l1 and to assume the position shown in Fig. 4.- so that it bears against T-l); inner wall of the casing, thus causing the compression member to interlock wit] the casing, and when said interlockinghas taken place, tubing 1 maybe screwed downward through member 5, thus expanding sleeve (3 so that it-completely fills the casing, and prevents water from flowing downward past the packer.
screwvt roaded, as shown in Fig. 5, for t e rece er a quick rotary 5 In order to prevent ring 12 from turning inner end enters the slot 15' in hub 11. In
the alined position, as shown in Fig. 2, pin 15 bears against 'one end of the slot and thus secures the object of its employment- This provision is made for the purpose of preventing ring? from assuming the lockmg osition w n the tubing is turned in the irection in' which it would unscrew, as otherwise it might be accidentally unscrewed and severed when in the well.
Provision is made for the passage of gas through the packer in the following manner:I-hrough the compression member'5 and the collar 13, I form a slot 16 which communicates with the annular space 8 and the chamber 9. .Inthe upper end of head 3 I drill downward as at 16 until chamber 9 is intersected,'thus forming a passage entirely throughthe packer, longitudinally through which gas may pass. A gas escape pipe 17 is then connected with the passage 16 in any suitable manner, which pipe 17 leads and conducts gas to' the surface of the ground. An anti frlc'tion ring or washer 18 15 interposed between the juxtaposed faces of head 3 and sleeve 6, to allow said head to I well, for the purpose set turn freely and without fi'ictionupon said sleeve.
What'I claim and desire to secure by Letters Patent is: I
In a wall-packer for wells, the combination with the'fluid-conducting tubing of a" well, of a flexible packing-member surrounding said tubing, a sleeve attached to said tubing and bearing against the upper end of said flexible member, there being an annular chamber between said tubing and said sleeve, a collar bearing against the lower end of said flexible member, sad
through which said tubing-his inserted, l y. means of a screwthread, for the purpose specified, a metallic sleeve resting in said assing through said packingits ufpperend positioned in collar and member, wi the lower portion 0 saidannular chamber, there being an eccentric hub upon said collar, and an eccentric ring'loosely mounted upon said hub, adapted to engafge the wall of the I orth.
In testimony whereof I aflix my signature 1 in presence of two witnesses.
