IMPROVEMENT IN EJECTORS FOR ARTESIAN WELLS.
Spcciiication forming part of Letters Patent No. 122,950, dated'Ja-nuary 23, 1872.
To all whom it may concern:
Be it known that I, MURDICK LYTLE, of Oil City, in the county of Venango and State of Pennsylvania, have invented an Improvement in Ejectors for Artesian Wells; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawing making part of this specification, in which- Figure 1, Plate 1, is a diametrical section through the lower portion of an ejector having my invention applied to it, and showing the parts in position for raising liquids. Fig. 2, Plate 1, is a similar view of the same parts, indicating them in the positions they assume when the ejector is receiving fluid from the well into its lower chamber. Fig. 3, Plate l, is a section taken through 'the lower section of the ejector in the plane indicated by line x fr. Fig. 4, Plate 2, shows a modification of the devices represented on Plate l.
Similar letters of reference indicate corresponding parts in the several figures.
This invention relates to an improvement on compressedair ejectors for Artesian wells, whether they supply coal-oil or water. The simplest form of a compressed-air ejector consists of va tube or case extending down into a well, with a valve in its bottom opening upwardly. The compressed air is forced into this case or tube, which closes said valve and forces the liquid up through a central tube having a valve at its bottom opening upwardly. As long as there is lair in the outer tube under pressure, the valve in the bottom thereof remains shut, so that it is necessary to remove the compressed air whenever it is desired to allow uid to en ter the ejector from the well cavities. The object of my invention is to provide certain means whereby the compressed air in the lower part of an ejector is caused to escape automatically whenever the fluidin said section becomes exhausted; and on the other hand, whenever the fluid rises to a given height in said section, the escape-vent is shut and the inlet for the entrance of compressed air is opened, as will be hereinafter explained.
The following description will enable others skilled in the art to understand myinvention.
[n the accompanying drawing, Plates l and 2. A represents the main tube or shaft of the ejector; B, a coupling-screw for connecting an enlarged tubular section, C, to the lower end of the tube A; and D represents afoot piece, which is screwed to the lower end of section C, and provided with an inlet-v al ve, a, through which iiuid from the well-cavities enters the said section. E is a discharge-pipe, which is considerably smaller in diameter than the main tube A, and'which passes down through a diaphragm, c, nearly to the bottom of the foot piece D, and terminates in a check-valve, b, opening upwardly. An aperture is made through diaphragm c, and provided with a valve, e, which, when open, allows compressed air from the main tube A to enter the chamber in section C beneath the said diaphragm, and to force any liquid which may be therein out through the discharge-pipe E. Another aperture, o, is made through the diaphragm c and coupling B, which, when open, allows the compressed air in section C to escape into the cavitiesV of the well. This latter aperture o is provided with a valve, e3, which is rigidly connected to valve e, so that when the latter shuts its aperture the valve e3 opens its aperture, and vice versa.
I will now refer to Figs. l and 2, Plate 1. The two valves e c3 have connected to them a tripping-rod, f, which terminates at its,lower end in a foot, j". The rod f extends down alongside of the discharge-pipe E and through a hollow iloat, G, which surrounds the discharge-pipe, and is guided thereby in its rising and descending movements. The object ofthe floating body Gr is to open and shut the valves e e3, as I will now explain. When there is no pressure of air in the chamber G the valve a will open and allow iiuid from without to enter this chamber C, (valve e being closed and valve e3 open,) the body G will rise, and continue to do so until it presses against the valves e e3 with sufficient force to open valve c slightly. Whenthis takes place valve e will be suddenly raised by the action of the iniiowing compressed air rushing from the tube A into the chamber C; at the same time the vent 'u will be as quickly shut by its valve e3, and valve a will also be shut. The iiuid is then forced up through discharge-pipe E until chamber C is emptied of its contents, at which moment the floating body G will lodge upon the foot j of valve-rod j, and by its Weight shut valve e and open valve e3, thereby cutting ofi' the influx of compressed air, and allowing that which was left in chamber C to escape through vent u into the Well-cavities. The valve a is then free to rise and allow chamber C to be again supplied with iluid, as indicated by Fig. 2.
In Fig. 4 a substitute for the rising and descending body G is represented. This consists of a flexible diaphragm, G, on which the base e1 of the valves e c3 rests. This diaphragm is applied to the upper funnel-shaped end of a vertical air-tube, G2. When the liquid rises in the chamber C to a given height the air which is entrapped in the tube beneath the diaphragm G will be compressed to such a degree7 by the Weight of the column of liquid in the chamber C, that the diaphragm Will bulge out and lift the valves e e3. When the liquid is nearly all forced out of chamber C the hydrostatic pressure on the diaphragm Will cease and the valves e c3 Will drop.
In all other respects the operation of the ejector of Fig. 4 is precisely the same as the one shown by Figs. l and 2.
Having described my invention, I claim as new in artesian-Well ejectorsl. The ej eetor for artesian Wells, constructed With the diaphragm c, which is perforated and provided with the valves e e3, applied and operating substantially as and for the purpose herein described.
-2. The ejector for artesian Wells, provided with the device G, operated as described, and With the valves c e3 and'diaphragmc, all combined, substantially as set forth.
MURDIGK LYTLE.
