PUMP FOR OIL-WELLS.
SPECIFICATION forming part of Letters Patent No. 794,104, dated July 4, 1905. Application filed November 29, 1904. Serial No. 234,796.
To all whom, it may concern:
Be itknown that I, MICHAEL HUBER, a citizen of the United States, residing at Mannington,in the county of Marion and State of West Virginia, have invented certain new and useful Improvements in Pumps for Oil-l/Vells, of which the following is a specification.
In the operation of oil and other deep wells it is necessary to withdraw the tubing for one cause or another. Usually the tube remains full of oil or water, according to the nature of the well. If oil, it is lost at the surface. In either case the liquid escaping at the surface as the joints are uncoupled causes inconvenience and is otherwise objectionable, because of the nuisance created.
This invention provides a relief of novel formation which is closed under normal conditions and opened as a result of the initial pull upon the tubing to withdraw it from the we For a full description of the invention and the merits thereof and also to acquireaknowledge of the details of construction of the means for effecting the result reference is to be had to the following description and accompanying drawings.
While the invention maybe adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in which- Figure l is a vertical central section of the lower portion of the tubing of an oil-well embodying the invention, the telescopic relief being extended and the outlet uncovered to admit of the oil or liquid contents escape.
Fig. 2 is a view of the parts shown in Fig. l,A
the telescopic relief being closed.
Corresponding and like parts are referred to in the following description and indicated in both views of the drawings by the same reference characters.
In order to distinguish the component parts of the tubing, the same are designated as follows: The lowermost section 1 is perforated and correspondsto the suction-pipe. The
Fig. 2 shows the normal position of the parts when the well is in operation, the tube 5 being at the limit of its downward movement and closing the outlets 7 and resting upon the seat 8. Should it become necessary to withdraw the tubing from the well either to remove obstructing matter, to recover a portion of the rod or the valve, or for any other purpose, the first movement of the discharge-pipe causes the tube 5 to move upward, thereby uncovering the outlets 7 and permitting the oil or other liquid in the tubceive the lower end of the tube 5 and apack- Y IOO covers the relief and permits the oil or liquid to discharge. ln order to prevent sand or other matter obstructing the working parts of the telescopic relief, a housing 13 is provided and consists of a tube of sufficient length to inclose said relief when extended,V
as shown most clearly in Fig. 1. The housing 13 is threaded at its upper end to the fitting 12 and encircles the fitting 9, ample space being provided between said housing and the fitting 9 to admit of escape of the oil or liquid when the relief is open.
Having thus described the invention7 what is claimed as new is# 1. In an oil-well, the combination of the tubing comprising a discharge -pipe and working barrel, a telescopic relief comprising a tube extended from the working barrel and having an outlet, a tube projected from the discharge-pipe and adapted to cover said outlet, and an interlocking connection between the two tubes to cause all the parts to move together after the tubes comprising the telescopic relief have reached the limit of their play in the upward pull upon the tubing when withdrawing the same from the well.
2. ln an oil-well, the combination of the tubing comprising a discharge-pipe and working barrel, a telescopic relief consisting of a tube extended from the working barrel and having an outlet near its lower end and a seeond tube projected from the discharge-pipe and adapted to cover said outlet, interlockin@ means between the twotubes, and a seat be ow the aforesaid outlet to receive the lower end of the tube connected with the discharge-pipe to insure the formation of a tight joint.
3. In an oil-Well, the combination of a working barrel, a tube having a lateral outlet near its lower end, a reducer-fitting connecting said tube and working barrel and having its upper portion forming a cup, a packing-gasket fitted in the lower portion of said cup, a discharge-pipe, a tube connected with the discharge pipe and telescoping with the tube having the outlet and adapted to close upon the seat provided in said cup, and interlocking means between the two tubes.
4. In an oil-well, the combination of a working barrel, a discharge-pipe, a telescopic relief consisting of a tube extended from the working barrel and having a lateral outlet near its lower end, a tube projected from the discharge-pipe, interlocking means between the two tubes, and a housing connected with the discharge-pipe and adapted to inclose the telescopic relief both when extended and closed.
ln testimony whereof l a'lliX my signature in presence of two witnesses.
