PUMPING OUTFIT.

Application filed July 25,

T 0 all whom it may concern.-

Be it known that I, THOMAS A. BRowN, a citizen of the United States, residing at Broken Arrow, in the county of Wagoner and State of Oklahoma, have invented certain new and useful Improvements in Pump ing Outfits, of which the following is a specification.

This invention relates to pumping outfits for deep oil and water wells, and the primary object of the invention is to provide a novel means for eliminating the necessity of pulling the rods and plunger each time the leather cups or washers on the upper working valve or plunger becomes worn, thereby resulting in the saving of time and labor caused by the pulling oi": the rods.

Another object of the invention is to provide an improved working barrel having formed therein a working surface, of a smaller diameter than the other portions of the barrel, and a novel sucker rod attachment embodying a pair of spaced operating plungers, the plungers being spaced, so that one of the same will be disposed in the working portion of the barrel, while the other plunger will be disposed above or below the working portion of the barrel, so that when the leather cups or washers or the plunger arranged in the working portion of the barrel becomes worn, the other plunger can be moved into engagement with the working portion of the barrel, and thereby eliminating the necessity of pulling the rod for repairing or renewing the leather cups.

A further object of the invention is to provide a novel means for operatively connecting the two plungers or working valves together, said connection providing means for holding the leather cups in position on the upper working valve or plunger, thereby eliminating the necessity of providing the usual nut for this purpose.

A still further object of the invention is to provide an improved barrel and plunger of the above character, which is durable and efficient in use, one that is simple and easy to manufacture, and one which can be placed upon the market at a reasonable cost.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying 1921. Serial No. 487,501.

drawings, forming a part of this specification, in which drawings:

higure 1 1s a detail perspective View of a surface equipment of a well pump with which the improved device is associated.

Figure is a longitudinal sectional view through a pump casing and my improved pump outfit, showing the lower working valve or plunger in its operative working position.

Figure 3 is a similar view showing the lower working valve or plunger moved below the working portion of the barrel, and the upper working valve or plunger moved into operative position in the working portion of the barrel.

Figure 4 is an enlarged fragmentary side elevation, partly in section of the improved. working valves or plungers, showing the means of connecting the same together.

Figure 5 is a detail section, taken on the line 5-5 of Figure 2.

Referring to the drawings in detail, the letter A indicates a pump casing; B the novel working barrel; C, the novel working valves or plungers; and D, the surface pumping equipment.

The surface pumping. equipment D can be or" the usual or any preferred type, and includes any preferred type of rod clamps 10, for engaging and clamping the polished rod 11, which is carried by the upper end of the sucker rod 12, which is connected in' the usual manner to the novel plunger or upper valve C.

The working barrel B is arranged in the well casing A in the ordinary manner, and is formed relatively long, for a purpose which will hereinafter more fully appear. As shown, the barrel B includes the cylindrical body 10 is also reduced in diameter, to tion thereof reduced in diameter, as at 16, which forms the working portion of the barrel. The extreme lower end of the cylindrical body 10 is also reduced in diameter, to the same size as the working portion 1.6, as at 17, for the reception of the standing valve 18, which is of the ordinary or any preferred construction, or make.

The improved operating valves or plungers C includes a dual valve construction, either of which is capable to be brought into play for forcing the fluid out of the well. As shown, this dual valve construction in eludes an 'upper valve or plunger portion 20, and a lower valve or plunger portion 21. These plungers are connected together by a novel form of coupling 22. The valve plunger port- ions 20 and 21 are of the usual or any preferred construction, and each includes the upper valve 23, and the leather cups or washers 2a, which are usually held in place, by means of the suitable nut. In this instance, the coupling 22 is employed for the lower end of the upper valve 20, whichztakesnthe" place of this usual nut, which is shown at 25 in the lower portion of the loweryalve 21. This coupling ll'l cludes a crown 26, which is perforated for permitting the fluid to [low therethrough, and the lower end of the same is provided with a socket 28 for receiving the stub 29 of the rod 22. The lower end of the rod 22 is connected in the ordinary manner to the valve 21, which as stated will be of the-ordinary or any preferred construction.

In operation of the improved pumping outfit, the sucker rod 12 with thedual plunger outfit is lowered into the barrel 13, until the lower plunger or operating valve 21 comes into the reduced port-ion 16 of the barrel B. The clamps 10 are then actuated so as to firmly clasp the polish rod 11,-after which the pump jack or surface equipment D is set in. operation. When the pump washers become worn to such an extent that they will not perform their functions and the fluid will not be pumped out of the barrel, the clamps 10 are actuated, so as to re lease their grip from the polish rod 11, which will be permitted to drop a predetermined distance which permits the lowering of the sucker rod 12 and the lowering of the upper valve 20 into the operating r reduced portion 16 of the valve .15. This brings a complete new valve into operation the washers or'leather cups of which have not been worn by frictional contact with the sides of the barrel. The lower plunger or operating valve 21, is then positioned below the operating or reduced portion 16 of the barrel, and the liquid is permitted to escape freely around. the sides thereof. After the upper valve 20 has been moved into the re duced portion of the barrel B, the clamps 10 are moved into operative position on the polished rod 11, and the pump is again started up in the ordinary manner.

From the foregoing description, it can be seen that an improved pumping outit has been provided, in which the necessity of pulling the sucker rods and plunger each time the washers or leather cups of the operating valves or plungers become worn is eliminated. By the construction, as shown and described, it is only necessary to pull the plungers one half as much as in the ordinary construction.

Changes in details may be made without ranged to fit one atatime in." the working portion of the barrel.

2. A pumping outfit comprising. a barrel having a working portion formed therein, said working portion extending only-a part of the length of the barrel, a standing valve disposed below the working portion. of the barrel. a reciprocating sucker rod, a pair of independent operating plungers carried by the sucker rod and spaced apart a greaterdistance than the length of the working portion of the barrel, the working. portion of the barrel being arranged to receive one of 1 the plungers at a time.
