JOSEPH ONEIL, OF TAYLORSTOWN, PENNSYLVANIA, ASSIGNOR OF TWO- TI-IIRDS TO FRANK L. MASSON, OF SAME PLACE, AND CHARLES O.
OHAMBERLIN, OF WASHINGTON, PENNSYLVANIA.
PUMP.
SPECIFIGATION forming part of Letters Patent No. 651,314, dated June 5, 1900. Application filed February 23, 1897. Serial No. 624,558. (No model.)
T0 @ZZ whom it may concern,.-
Be it known that I, JOSEPH ONEIL, a citizen of the United States, residing at Taylorstown, 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 vertical elevation of my improved pump and the inclosed cage and cups beneath the same. Fig. 2 is a vertical section of Fig. 1. Fig. 3 is a plan of a sleeve secured on the upper end of the stationary stand-pipe. Fig. 4 is a side elevation of the upper end of the stand-pipe and sleeve. Fig. 5 is a vertical section through the pump-seat and the adjacent tubing, showing the cups on the valve-body, the inclosed cage, and the stuffing-box broken off of the pump-valve.
The purposes of my invention, generally stated, are to devise an inexpensive form of pump which shall do away with the ordinary working barrel and also with a plunger provided with cups. A. further purpose is to make the pump self-lifting to a given degree, thereby greatly reducing the strain ou .the sucker-rods and enabling me to use alighter form of-such rods.
It is well known to those skilled in the art`- that the working barrels of the ordinary pump are by far the most expensive portion thereof. They require to be machined with the greatest accuracy and must be carefully polished internally to accurately iit the plunger. It is further familiar to those acquainted with the art that the cups on the plunger-s are a source of constant annoyance and delay and expense, particularly in wells containing Floating sand, since such cups will be cut and require frequent renewal.
In the present invention I have no working barrels nor any reciprocating plunger nor any cups to form a packing between said working barrel and plunger,l as will be more clearly brought out below.
In the accompanying drawings,which make part of this specification, 2 is the ordinary standing valve-body, provided with the cups body is screwed any well-known form of cage 3, provided with ball-valve 4, seated upon the valve-seat 5, the throw of said ball-Valve being limited by the inwardly-projecting lugs- 3, The parts thus farmentioned are old in the art.
I now come to those parts which I claim to be distinctively new` in themselves and new in combination with the parts just described.
6 is a hollow stand-pipe secured to the upper end of cage 3 and like it remaining stationary in the well, except when withdrawn for repairs, &c. The bore of this hollow stand-pipe connects with the bore of the cage and valve-body. The hollow stand-pipe 6 is provided at its upper end with a sleeve 7, having longitudinal passages 7, The sleeve 7 does not act as a plunger, for it remains stationary and only loosely iits in the shell to be described.
8 is a reciprocating shell which moves upon the stationary stand-pipe 6 as a guide, and a close joint between the two is secured` by means of the stufling-box 9, gland 10, follower 11, and packing 12. To the upperend of said reciprocating shell is secured the ordinary subpiece 13, on which rests the valve-seat 14, supporting ball-valve 15 in open cage 1G, screwed to subpiece 13.
To the upper end of cage 16 are secured in the usual manner the sucker-rods.
As shown in Fig. 5, 17 is the pump-seat, A
which incloses the valve-body and closed cage, said pump-seat 17 being interposed between and screwed to two sections of tubing 18 and 18. This is a construction which I prefer for the pump-seat when the pump is put into a well with the tubing; but-in cases where the tubing is already in and it is not desirable to remove the tubing from the well to insert the pump-seat my pump can be set on top of the working barrel already .in the well, and thus obviate the necessity of drawing the tubing.
The operation of the pump is as follows: When the sucker-rods are lifted, the shell S will rise, being guided in its movement by a rubbing contact between its stuiing-box and the vertical stand-pipe 6. The displacement of the oil occasioned by the upward movement of the shell 8 will cause an inrush of the oil through the passage b, raising the ballvalve 4, and through the Vertical stand-pipe 6 into the interior of the shell 8. In the meantime the oil which has previously been caught between the under side of the sleeve 7 and the upper side of the gland 9 will escape as these parts approach each other through the channel 7 7a into the upper part of the shell 8. On the downward movement of the suckerrod the shell 8 would be depressed, the ball 4 will seat itself, and the oil in the shell 8 will pass up through the subpiece 13 and raise the ball 15 and so pass up the well. Itwill be further observed that owing to the difference in area between the sleeve on the upper end of the stand-'pipe 6 and the stuffing-box at the bottom of shell 8, the well-pressure in an upward direction .against the Linder side of said stuffing-box will be exerted on a greater cross-section than the well-pressure in a downward direction upon the upper side of the sleeve. Hence the well-pressure upwardly will overbalauce to a certain extent the wellpressure exerted downwardly and will tend to this extent to help raise the suckerrods. This is directly contrary to the ordinary operation of the usual pump, since in lifting the ordinary pump not only lifts the weight of the sucker-rods, but must also lift the weight of the fiuid in the well above.
It should be further noted that the only packing used between the moving and the stationary parts of the pump is an ordinary packing 6a', which is `well-nigh inaccessible to the sand and which cannot be so easily cut as the oldstyle cups. This packing lits around the stand-pipe 6 and obviates the necessity of a carefnllybored and polished working barrel. The construction` is therefore cheap, simple, and not requiring such frequent renewals. The shell 8 is only an ordinary tube, requiring no special machining or fitting.
The function of the sleeve 7, as heretofore l stated, is not to act as a piston or plunger, but
it merely acts as a collar to lock against the upper end of the gland 9 when it is desired to draw the entire apparatus from the well.
Various changes may be made in the details of construction and fitting together of the parts while still retaining the broad features of my invention, and I do not wish to limit myself by implication to any special restricted features of construction unless such features are expressly enumerated in the claims.V
Having described my invention, I claim- 1. In pumps, the combination of a standpipe iixed in the well; tubing for said well; a tube within the tubing adapted to recipro-v cate upon said pipe; sucker-rods from which said tube is suspended and a stuflingbox carried by the reciprocating tube and interposed between said tube and said stand-pipe.
2. In pumps, the combination of a standpipe fixed in the Well; a collar having duidpassages on the upper end of said stand-pipe; tubing for said well; a tube within the `tubing adapted to reciprocate upon said standpipe; sucker-rods from which said tube is suspended and a stuffing-boxinterposed between said stand-pipe and the lower end of said reciprocating tube.-
3. In pumps, the combination of a stand= pipe fixed in the well; tubing for said Well; a tube within the tubing adapted to reciprocate upon said stand-pipe the annulus of said tube having a greater cross-sectional area than the cross-sectional area of the stand-pipe; sucker-rods from which said tube is suspended and a stufing-box interposed between said stand-pipe and the lower end of said reciprocating tube.
4. In pumps, the combination of tubing; a pump-seat interposed between and secured to two sections of the tubing; a valve-cage sup ported upon said pump-seat; a stand-pipe secured to said valve-cage; a tube suspended within the tubing from the sucker-rods and adapted to reciprocate upon said stand-pipe; said sucker-rods; and a stuffing-box with or dinary packing interposed between said standpipe and the lower end of said reciprocating tube.
In testimony whereof I have hereunto set my hand this 16th day of February, A. D.
