Dee. 3, 1929. H. s. BERKEY PUMP PLUNGER VALVE AND STEM HuaH 5. BER/Ey GrroR/vgy Filed May 24, 1927 Patented Dec. 3, 1929 1 UNITED STATES HUGH S. BERKEY, OF HUNTINGTON BEACH, CALIFORNIA PUMP PLUNGER VALVE AND STEM Application led May 24, 1927.

Mypresent invention relates to improvements in deep well pumps; and more particularly to deep well pumps in which provision is made for the positive opening and closing of a working valve incidentally to the reciprocation of a plunger.

As is well known, in the` operation of reciprocating` pumps by'means ofv sucker rods whose sections are connected by means of threaded couplings,suclrsections are liable occasionally to separate; and efforts to establish connection therebetween have heretofore been complicatedor defeated by a tendency of the lower or fish sections torotate, instead of remaining stationary, during efforts to reunitesaid sections. Itis accordingly an object of my invention to provide means for preventing relative rotation of a sucker rod y section which extends into a reciprocable plunger.

Further l objects .of my invention, including the use of a novel valve which maybe referred to as an inverted plumb-bob, positively `held against a shoulder and seated reciprocably within anelongated cage, and optionally involving the use of a novel valve guard and/or a reversible valve seat which serves as a coupling, may be best appreciated from the following description of `an illustrative embodiment of my invention, taken in connection with the appended claims and in the accompanying drawings, in which l Fig. 1` may be referred to as a substantially median section through-a pump organization embodying my invention7 partsbeing broken away.; v w l y Fig. 2 is an enlarged view, comparablewith the upper portion ofFig. 1, but talien in a plane at right angles thereto,-substantially 0 `as indicated by the line 2-2 of Fig. 1.

der of any desired character and length, 12 is a plunger cylinder,-which may closely interfit, although adapted to reciprocate therein; and the upper end of said plunger is shown as provided with a head member 13, which is laterally cut away,-to provide parallel vertical faces 14;, 14', through which may be cut iuid outlet apertures 15, 15', and/ or other apertures as best shown in Figs. 2 and 4.

Instead of providing the mentioned plunger, or its equivalent, with an upwardly opening valve, or securing said plunger directly to a sucker rod comprising a lowermost section or coupling 16, I show the mentioned rod or coupling as directly connected only with a subsidiary or valve-operating rod 17,-this subsidiary rod being capable of a limited reciprocation relatively to said plunger, through a vertically-extending aperture 18 in the head 13, or its equivalent. The extent of this relative reciprocation may be limited by, for example, the adjustment of a. lock nut 19, or its equivalent, shown on said subsidiary rod and as adapted to engage an oppositely disposed shoulder 20, on said head; but it should be understood that a primary purpose of the lost motion or relative movement here referred to its a suitable and positive manipulation of a downwardly-opening valve, of any preferred character, secured at 30 or near the lower end of the subsidiary rod 17. I show a double-ended valve seat element 21 as secured relatively to the cylindrical plunger body 12 by means of an intermediate or male-female coupling element 22, provided with a vertically-extending passage 23, of sufficient diameter to permit not only a free reciprocation of the subsidiary rod 17, or its equivalent, but also a free passage ofpumped liuid therethrough; and, in case it is considered desirable to protect the mentioned parts, and/or a valve element 24, carried by the subsidiary rod 17, by means such as a guard element 25 (shown as resembling in `form an elongated cage, and optionally provided with a threaded opening 26, suitable for use in lifting a standing valve organization, not shown, at will) this protecting or guard element may advantageously be so employed as to serve as a lock nut, holding the seat 100 ,circular section 31 ofrod 17.

element 21, or its equivalent, securely in an adjusted position relatively to the plunger cylinder 12 or the intermediate member 22, or an equivalent part.

Although the valve element 24: may be of any preferred character, I show the same as frusto-conical in general form, as retained in engagement with a shoulder 27 at the upper end of a reduced portion 28 of the rod 17, as rounded forV avqstream-line effect at its lower end 29, and as retained by means of a nut or nuts 30 upon a. threaded extension of said reduced portion.

The subsidiary rod 17 being provided with a hexagonal or other non-circular section 31, the apertured plunger head 13 is shown as so shaped, belowI the" circular opening 2O through which the said rod extends, as to yprovide parallel, flat `surfaces 32, 32', between which a hexangularA body 33 may be slidably interitted. lThis slidable body is shown as provided with a non-circular opening, corresponding in shape to the outline of the non- The slidable body 33'may` be held in place by means such asa nut 34,; and its'length, position and rela- 'tionship tothe

The Ydescribed lost-motion relationship between the subsidiary rod 17, carrying and operating the valve 24, is obviouslv such that,

Aduring each descending stroke, the valve 24 is opened beforek the plunger descends; and said `valve isvafterwards closed before the plungerrises. The shape ofthe valve 24, as

related to its seat, is favorable not only to .tight closure but to free flow. The fit of the 'A pump plunger 12 within the outer cylinder u 11 maybe such as to permit, upon a suitable application of rotative power, a transmission `of torque through all of the mentioned movi able parts, in such manner that thread 26 may engage (whenever the plunger is lowered for rthat purpose)l any special upstanding member correspondingly l threaded for use in pulling a standing valve organization not shown) but ythe lit ofthe plunger within its cylinderA and its massare nevertheless to be vpresumedsuch as ordinarily to prevent free relative rotation therebetween. Accordingly, the subsidiaryrod 17, with any number of sections of 'sucker rod'attached thereto, is to be Y"understoodasfsuiiiciently held, by means I including'the described interlitting n'on-cir- I cular member and

to prevent any rotationV thereof, during the screwing or unscrewing of sections of pump rod, or during analogous operations.

Obviously any desired valves and/or auxiliary devices, not shown, may be placed above and/or below a plunger of the indicated character; said plunger may be of any preferred type, with or without special packing; and although, for convenience of description, I have used terms as above and below, it will be appreciated that a plunger constructed and equipped in somewhat the indicated manner may be used in any position whatever and operated by any desired means. Although I have herein described a single complete embodiment of my invention, it should be understood not only that various features thereof may be independently used but also that numerous modilications might be devised, by those skilled in the arts to which this case relates, without the slightest departure from the spirit and scope of this invention, as the same is indicated above and in the following claims.
