JOSEPH H. DUKE, OF CORRY, PENNSYLVANIA, AND JOHN F. BRAY, OF
' SALTPETRE,
DEEP-WELL PUMP-VALVE.
SPECIFICATION forming part of Letters Patent N 0. 751,482, dated February 9, 1904.
Application filed March 11, 1903.
To all whom it may concern.-
Be it known that we, JOSEPH H. DUKE, re-
siding at Corry, in the county of Erie and State specification.
Our invention relates to deep-well pumpvalves; and it consists, substantially, in mechanism for drawing the standing valve thereof.
In operating deep oil or Artesian wells the pump barrel and valve mechanism .are attached to the lower end of the well-tubing at or near the bottom of the well, and the pump-piston or working valve therein is operated by means of a sucker-rod connected therewith and extending up through the tubing to the top of the well, and the standing valve is seated in the lower end of the working barrel. For drawing the standing valve various devices are employed, and one commonly used consists either of a nipple on the lower end of the pump-piston or working valve adapted to screw into a screw-threaded" socket in the yoke or bail of the standing valve or of a nipple on the top of the standing-valve yoke or bail and a corresponding screw-threaded socket in the lower end of the pump-piston or working valve. In both of these constructions, however, it frequently,
happens that the pump-piston or working valve is allowed to drop upon the top of the standing-valve, so as to injure the nipple and screw-threaded socket sothat they will not operate, making it necessary to withdraw the rods and pump-piston or working valve from the well and replace the rods again therein with a suitable tool for engaging and withdrawing the standing valve. In order to overcome these difliculties, we have provided an Serial No. 147,318. on model.)
extension upon the lower end of the working valve, conslsting, substantially, of a stem car rying a nipple and having an internally-screwthreaded sleeve thereon adapted to engage the yoke or bail of the standing valve when brought into contact therewith, so as to permit the nipple to be screwed down into the screw-threaded socket in the standing valve without injury. I
The features of this invention are hereinafter fully set forth and explained, and illustrated in the accompanying drawing, in which the figure is a vertical section of a deep-wellpump working barrel, with a standing valve and pump-piston or working valve therein embodying our invention.
In the drawing illustrating our invention,A
is a working barrel of an Artesian or deepwell pump, to the lower-end of which there is coupled the usual perforated section B by means of a coupling O, provided with astanding-valve seat O,in which a standing valve 1) of the usual constrution is seated, and in the top of the yoke or bail of said valve there is a screw-threaded socket cl. In the working barrel A, above the standing valve D, there is a pump-piston or working valve E of the usual construction, which is coupled to the lower end of the suction -rod F in the usual manner.
Upon a screw-threaded projection E on the 'loWerend of the pump-piston or working valve E we screw a stern H, centrally chambered out at H, so as to communicate with the central opening in the valve E, and also provided with openings it, leading into the chamber H to admit the fluid being pumped thereto. "In the center of the lower end of the stemH there is secured a nipple I, adapted to be screwed into the screw-threaded opening d in the standing valve D, and on the en larged screw-threaded periphery J of the lower 1 end of the stem H there is an internally-screwthreaded sleeve K, which is retained on the lower end of the stem H by means of a screwthreaded cap J, which permits the end J of the stem H to be screwed down into the sleeve K, but prevents its being unscrewed out of the upper end of said sleeve. In the lower end of the sleeve K there are notches 16, which when the sleeve K rests upon the top of the standing valve D engage the arms (Z of the yoke or bail of the standing valve and prevent the turning of the sleeve K when the stem H is being screwed downward therein and also operate to guide the nipple I on the stern H into the screw-threaded opening (Z in the standing valve D.
In the ordinary operation of the valves the nipple I is normally drawn up inside of the sleeve K, as illustrated in the drawing, so that if by accident or by other reason the pumppiston or working valve is dropped, so as to contact with the standing valve, the nipple I will not contact with the screw threaded socket cl in the standing valve D, as the end of the sleeve K will contact with the yoke of the valve and prevent it. desired to draw the standing valve, the valve E is lowered until the lower end of the sleeve K engages the arms cl of the yoke or bail of the valve D. The valve E is then rotated, which serves to screw the end J of the stem H down into the sleeve K until the nipple I thereon is screwed into the screw-threaded opening d in When, however, it is the yoke of the valve D, when the two valves can be withdrawn from the tubing together. Having thus described our invention, so as to enable others to construct and use the same, what we claim as new, and desire to secure by Letters Patent of the United States, is-
The combination with a deep well pumppiston or working valve, of a stem depending from the lower end thereof, a screw-threaded nipple on the lower end of said stem, a screwthreaded shoulder above the nipple on said stem, and a rotatable sleeve on said stem having internal screw-threads engaging the screwthreaded shoulder on the stem, and also having notches on its lower end, substantially as and for the purpose set forth.
In testimony whereof we aflix our signatures in presence of witnesses.
