WILLIAM O. ROBBINS, OF NEW YORK, N. Y.
EJECTOR FOR OI L-WELLS.
SPECIFICATION forming part of Letters Patent No. 254,381, dated February 28, 1882.
' Application filed August 5, 881. tNo model.)
To all whom it may concern Be it known that I, WILLIAM 0. ROBBINS, of the city, county, and State of New York, have invented a new and Improved Ejector for Oil-Wells, of which the following is a specification.
The object of my invention is to provide a new and improved ejector for raising oil from wells.
The invention consists in a tube entering the stand-pipe of an oil-well at the upper end of the same, passing down to the bottom of this stand-pipe, and then bent upward, the lower opening being a short distance above the bend, so that compressed air forced through this-tube will force the air in the stand-pipe upward, a checlcvalvein the bottom of the stand-pipe preventing the back-flow of the oil.
In the accompanying drawings, Figure 1 is a longitudinal sectional elevation of my improved ejector for oil-wells. Fig. 2 is a longitudinal elevation of a slightly -modified construction of the same.
Similar letters of reference indicate corresponding parts.
A tube, A, enters the stand-pipe B of an oilwell, O-that is to say, the pipe through which the oil is to be raised-at or near the upper end of the same, and extends down to near the bottom of this stand-pipe B, and is bent to extend in the opposite direction-that is, upward-a short distance, so that the lower opening of this tube A will face upward and will be a short distance above the bend of the tube A. The' stand-pipe B is provided at its lower end with. a check-valve, D, of any desired construction.
The upper end, E, of the stand-pipe B extends to an oil-receiving tank, F. The tube A is to be of one-half the diameter of the stand-pipe B; but this tube may have a diameter greater than half the diameter of the stand-pipe, and in this case the bend of this tube must be contained in an enlargement, G, of the stand-pipe B, as this tube could not be passed (if doubled over) into the stand-pipe. The upper end of the tube A is connected with an air-compressor, or a reservoir for compressed air, whereby compressed air will be forced through the tube A and will be emitted from the lower opening of the same. This compressed air forces the oil in the stand-pipe upward and out of the upper openingofthe same, and thus creates a vacuum in the lower end of the stand-pipe, causing the check-valve D to be raised and oil to pass from the well into the stand-pipe.
Iain'aware thatejectors have been constructed consisting of a tube for conducting compressed air to the bottom of astand-pipe of a well, and I do not claim this, broadly. With my ejector the air-tube A passes down through the stand-pipe and occupies part of the same, and the quantity of oil in the stand-pipe willbe considerably less than that contained in a stand-pipe not containing an air-tube. Furthermore, the ejector, Fig. 1, can be placed into any stand-pipe in the same manner as a suckerrod is passed into it, and no special chambers or devices need be provided at the lower end of the stand-pipe-that is, the lowest section of a stand -pipe which has been used with a pump need not be raised before applying this ejector; but the air-tube can be inserted and placed in the stand-pipe without altering the same. I
This device can be used for raisin g any other liquid as well as oil.
For inserting the ejector-tube A shown in Fig.1, the pipe B is first put down and the tube A then passed down through it, and independent elbow-sections then put upon the same at the top; In putting down the form shown in Fig. 2 the sections of tube A are put in simultaneously with the corresponding sections of )ipe B. Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- An ejector for an oil-well, consisting of the combination, with the stand-pipeB, having an inwardly-opening valve, D, of the tube A, contained within the pipe B throughout its length,
and having its lower end turned up within the Witnesses:
