PUMP.l
SPECIFICATION forming part of Letters Patent N o. 602,869, dated April 28, 1898.
Application filed February 17, 1897. Serial No. 623,793. (No model.)
To L7/Z whom it may concern:
Be it known that I, Josnrn ONEIL, acitizen of the United States, residing at Taylorsrown, in the county of Washington and State of Pennsylvania, have invented or discovered new and useful Improvements in Pumps, of which the following is a specification.
In the accompanying drawings,which make part of this specification, Figure 1 is a broken vertical section showing that portion of my apparatus which adapts the pump to use with a wire line. Fig. 2 is a like view of the pumping apparatus proper. Fig. 3 is a like broken locking apparatus, showing the springs compressed. Fig. Il is a plan view of the same. Fig. 5 is a section on line 5 5 of Fig. 3. Fig. 6 is a side elevation of the interior apparatus of the fluid-distributor. Fig. 7 is a vertical section of Fig. 6. Fig. 8 is a vertical section of the shell of the iiuid-distributer.
The purpose of my invention, generally sta-ted, is to devise a pumping apparatus having two pistons of equal diameter and so arranged and combined with accessory mechanism that a wire line may be used in pumping in place of the ordinary sucker-rods. To accomplish this purpose, I so arrange my mechanism that the fluid will automatically make a downdraft on the wire line and so keep the same taut on the downward stroke of the pump. My mechanism may be used with the ordinary sucker-rods, but it is not primarily intended for such use. The apparatus is peculiarly adapted for use in oil-wells, but can be used in water and other wells.
In the several drawings, which make part of this specification, 2 is the tubing of an oilwell.
3 is the lower or standing valve of the ordinary working barrel 4.
5 is the pumppiston proper, having the usual cups.
6 is the working or upper valve.
7 is the valve-rod.
The tubing at its upper end is screwed to a coupling S,which in turn is screwed to the lower end of the shell 9 of a huid-distributor." The upper end of the fluid-distributer is likewise screwed to another section of the tubing. The construction of the luid-distributer is clearly seen in Fig. S. It has a longitudinal passage extending along its left side marked 82. On the side of the duid-distributor is a spring-seated valve 8b, held open by the pressure of the iluid, as hereinafter described. The valve-passage SC communicates with the interior of the i'luid-distributer.
I will now describe the mechanism built up in the interior of the luiddistributer. This mechanism is preferably made of a number of pieces for convenience in manufacturing and assembling. At the lower end of the distributer is the piece 9', having lateral openings 9'9". This piece is threaded atits lower end into a sleeve 10,which in turn is threaded at its lower end into the upper end of the Working barrel 1. The joint between the upper end of sleeve 10 and coupling 8 is packed at l1. The valve-rod 7 passes through the piece 10. Screw-threaded to and supported by the piece l0 is stufling-box 12, packed at 12 and which acts as asupport for the stem 13 of vertical spring-seated valve 1392 Said vertical valve 13a is substantially opposite valve Si. la is the valve-seat for said valve 13a and has vertical openings 14a 14n. Said valve-seat 14 is threaded to the lower end of a supporting-piece 14,which in turn is threaded to an auxiliary working barrel 15, in which moves draft-piston 16.
17 is suitable packing at the upper end of valve-seat 14. Valve-rod 7 extends from piston 16 to subpiece 18, to which itis screwed, by which connection is made with jar 19, above which is attached the wire cable.
I will now describe the locking mechanism for holding in place the various devices contained in the iiuid-distributer and the auxiliary working barrel 15.
2O is a casting, shown as hexagonal and having lateral ports 2Osi on four of its sides and having secured to the other two sides the leaf-springs 21 21. The casting 2O has a depending bottom iiange 20", by which it is threaded t0 the auxiliary working barrel 15, in which plays the draft-piston 16.
22 is a short pipe-section passing loosely through the center of casting 20 and screwed to cross-head 23, which has side slots 23a 23, through which pass springs 21 2l. Subpiece 18 rests loosely upon top of pipe 22.
24: is a collar connecting two of the sections of tubing, said collar having an internal pe- IDO vious strokes of the pump descends with said draft-piston, and the oil standing in the tubing follows, iiowing down through lateral ports 20 20a, thus keeping the space above the draft-piston charged with oil. It should be premised that when the pump is first started it is primed by pouring in several buckets of oil, so that there may be a.
sufficient weight upon the draft-piston-.16 to keep the wireline taut until the pump is fully working. After the pump is fully working it willl be seen that the upper surface of' the draft-piston 16 has the full pressure of the column of oil upon it, and this pressure will tendon the downstroke of the pump to return thepump-piston proper and the draftpiston to their appropriate places and keep the-wire line taut. der side of the draft-piston 16 is practically nil, as the chamber immediately below saidA piston is kept free from oil by valve 13%,
Should, however, any oil seep into saidchamber, itjwill be expelled onthe downward movement of the piston and the pressure on the upper side of the draft-piston 16 be removed. This expulsion is accomplished by the fact that the valve 13 will yield against thepressure of the oil which has leaked in, andthe oil will pass through the openings 14ea 14 and out` into the well through the side valve 8".'
VVhenit is desirable to pull out the pump:
andthe mechanism connected'with and above the same, itl is accomplished by pullingup, draft-piston. 16 until it strikes against the lower end of pipe-section 22, ywhich is secu red The resistance on the un-` to cross-head 23. The upward movement being continued, cross-heady 23 rises, compressing the bowed springs 21 21 until their upper ends slip inwardly past the flange 24, and the lock heretofore made between said iiange and the upper ends of said springs is released.
The iiuid-pressureon the inside of the fluiddistributer now seats valve Si and prevents the escape of oil from the tubing, and thus avoids repriming the valve.
Various changes may be made in the form, larrangement, and proportion of the various parts, while still preserving the spirit of my invention, and suchy modifications I propose to cover in the annexed claims.
Having described my invention, I claim- 1. The combination of a working barrel; a piston working therein; an` auxiliary pumpbarrel; a draft-piston working therein; a valve-rod connecting said pistons anda valvevented chamber immediately below the draftpiston for the purpose of relieving the under side of said piston from pressure on the downward movement-ofV the pump.
2. In pumps the combination of a double piston; al lower piston and an intermediate luid-distributer provided with a passage to pass the fluid up the well and a valve-controlled discharge-passage to relieve the pressure beneath the upper piston.v
3. In. pumping devices, a lock, consisting of a base-piece springs attached to said basepieoe; a shoulder on the connecting-collar between the well-tubing'and the pumping device, saidl shoulder engaging said springs when the pumping device is in position, and `a cross-head, through which said springs pass, lloosely mounted on the Valve-stem, and fitted, 5to be forcedup, and release said springs from lengagement with said shoulders.
' In .testimony whereofL I- have hereunto set fmy hand this 21st day of January, A. D; 1897. JOSEPH ON EIL.
