UNITED STATES PATENT OEEICE.
GEORGE M. MOIVBRAY, OF TITUSVILL, PENNSYLVANIA.'
IMPROVEMENT IN EJECTOFLS FOR. OIL-WELLS.
Specification forming part of Letters Patent No. 111,@7 @s dated November 1, 1864.
To all whom it may concern:
Be it known thatI, GEORGE M. MOWBRAY, of Titusville, in the county of Crawford and State of Pennsylvania, have invented anew and useful Improvement in Pumps or Ejectors for Oil and other Wells 5 and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure l represents a vertical section of the apparatus applied to a well. Fig. 2 is a vertical section, on a larger scale, at the line m a', Fig. 3, of parts of the concentric tubes, and of the guides, to be hereinafter described. Fig. 8 is a horizontal section of the same at y y, Figs. l and 2. Fig. 4 is an elevation ofthe anchor or step employed to support the inner tube or the deiiector. Fig. 5 is a top view of the said anchor or step. Fig. 6 is a horizontal section thereof' at z z, Fig. 4.
Similar letters of reference indicate corresponding parts in the several views.
The nature of my invention consists, iirst, in providing the inner tube with an ges or guides, which, projecting from its periphery and elongated in the line of the axis, serve to preserve it concentric with the outer tube, leaving an annular space around it for the rising column of oil or water; secondly, it consists in an anchor or step which supports the deflector at the lower end of the inner tube at the required height above the bottom of the shaft, and by its grip upon the ground preserves the deiiector from rotation when the inner pipe is rotated for the purpose of adjusting the size of the annular space between the deliector and the bulb.
Ais the outer pipe, and B the inner pipe, down which latter a body of air is forced by an air-pump, O, driven by any suitable -motor. This air issues in a highly-compressed stream through the annular orifice between the del'lector D and the bulb E.
To preserve the inner tube in a central position relatively to the outer tube, I employ iianges F, of a segmental or other shape, which are attached to a sleeve, ring, or collar, II, slipping upon or attached to the inner pipe, B, which flanges are perpendicular and in contact, or asnearly so as the nature of the case will permit, with the inner sides of the outer pipe,A, to prevent the sagging of the inner pipe against the outer one. These flanges are made as long as may be necessary for strength, but are made narrow, so as not to oppose any great obstacle to the rising stream of air, oil, or water, and of course their length is parallel with the axis of the pipe. These wings may be cast upon the orf dinary couplings which connect the sections of tubing.
I do not confine myself to the exact arrangement shown, but may vary it by modifications of detail which need hardly be described, as they would occur to any intelligentmechanic.
The anchor or step at the bottom of the shaft or well, and to which the detlecting-cup is screwed or riveted, consists of a tripod, I, with legst' t' fi and shaft J, with a flanged or armed socket, K. Its purpose is to support the weight of the inner pipe by resting on the ground and maintain the cup in a xed position, so as to permit the raising or depressing of the air-tube and the conical bulb attached thereto, and consequently opening or partially closing the orifice through which the air issues, without removing the same from the wellthat is to say, the lower cup having a determinate position while the air-tube and its attachments are adj ustable relatively there to by rotation of the pipe in the deectingcup through which it passes.
So uncertain and fickle are these wells in many instances that when a person has got a well into running order he would rather forfeit a thousand dollars than have to draw his tubing for the adjustment of the orifice or other purposes, and this on account of the difliculty in adjustment in exactly the same condition, which may be the only one in which the apparatus can be operative, owing to causes imperfectly understood, purely conjectural, and incapable of examination at the immense depth.
Having thus described my improvement, what I claim as new therein, and desire to secure by Letters Patent, is
l. The wings or flan ges F, substantially as above described, and for the purposes set forth.
ments in ejectors for oil and other Wells I have signed my hand this 29th day of Sep tember, 1864.
GEO. M. MOVVBRAY.
