OIL WELL PUMP.
UNITED STATES PATENT j OFFICE.
j ADAM RosENKRANz, oF ALLEGHENY,"PENNSYLVANIA,
OIL-WELL PUMP.
SPECIFICATION forming part of Letters Patent No. 530,350, dated December 4, 1894.`
Application filed August 22, `1893. SerialNo.433.736- (N o model.) l
To all whom it may con/cern.:
Beit known that I, ADAMROSENKRANZ, of
Allegheny, in the county of Allegheny andv State of Pennsylvania, have invented a new and Improved Oil-Well Pump, of which the following isa full, clear, and exact description.
` v The objectof the invention is to provide a new and improved pump,whicl1 is simple and durable in construction, very edective in operation, and more especially designed for use in oil and other wells, and arranged t-o prevent grit or other impurities, from passing between the plunger and the parts in which it works, to prevent injury to the plunger.
The invention consists of certain parts and details and combinations of the same, as will be hereinafter described and then pointed out in the claim.
Reference is to be had to the accompanying drawings, forming apart of this specification, in whichsimilar letters of reference indicate corresponding parts in all the views.
Figure 1 is a sectional side elevation of the pump. Fig. 2 isan enlarged sectional side elevation of the plunger on the line 2-2 in Fig. 1. Fig. 3 is an enlarged sectional plan view of the improvement on the line 3-3 of Fig. 1 and Fig. 4 is an enlarged sectional side elevation of the suction end of the pump casiing, on the line 4-4 in Fig. 1.
As illustrated in Fig. 1, the pump is arranged in the oil well casing A, into which extends the tubing B, supporting at its lower end the pump casing C, comprising abarrel D attached at its upper end to a stufling .box Df connected bya cylinder D2 with a stuliing box DB screwed on the lower end of the tubing B. The barrel D and cylinder D2 are somewhat less in diameter than the oil well casing A, while the stuffing boxes D andD3 t snugly in the said casing, as shown. On the lower end of the barrel Dis secured a cap E, carrying the perforated suction pipe F extending into the liquid to be pumped out iwf the oil Well casing A, as plainly shown in ig. 1. 1 i
In the cap E is arranged a valve casing G containing a ball valve Gr, through which the oil can pass into the barrel D; and on the upper end of the said casing G is arranged a threaded boss G2 adapted to be engaged by the threaded lower end H of the plunger H, made hollow, and extending into the barrel D and through the stuffing boxes D', D3 and cylinder D2, up into the tubing B to connect at its upper end with the usual sucker rod B operated from the ground in the usual manner. In the lower end of the hollow plunger rod H is arranged au inlet valve H2 and at the upper end of the said plunger rod is arranged a discharge valve H3, both valves being preferably of the ball construction, as plainly shown inthe drawings.
In the cylinder D2 are arranged two sets of packing I and I', preferably made of hemp or other suitable material, coiled around the plunger rod H so as to pack the same. The packing I rests with its lower end on the somewhat inclined bottom of the stuffing box D and is pressed on, on top, by a collar l2 through which passes loosely the plunger rod H. The collarl2 is provided with ashoulder formed by a central inward projection or sleeve I4. yThe other packing l rests with its upper end on the under curved surface of the topstufting box D3, and the lower end of thesaid packing I is engaged by a collarla, similar in construction to the collar l2 for the packing I. Between the two collars Pand I3 a coil springJ is interposed, which at its ends encircles the projections 140i the collars, and serves to press the collar l3 upward and the collar I2 downward, so as to Iirmly force the packings in Contact with the plunger rod H and against theircorresponding stuftingboxes D3 and D. `The plunger H is made tapering at its lower end, so that it can be readily withdrawn and re-inserted without removing the pump barrel.
The stuffing box D3 is provided with an upwardly flaring bore, to permit of readily inserting the plunger.
When the several parts are in the position illustrated in Fig. 1 and a reciprocating motion is given to the plunger rod H, in the usual manner, by working the sucker rod B then the liquor in the lower end of vthe oil well casing Ais drawn into the suction pipe F and passes to the valve casing G and valve Gr, into the barrel D, on each up-stroke of the said plunger rod. On the down-stroke of the said plunger rod H, the valve Gcloses and the valve H2 opens, so that the liquor in Ythe barrel D passes into the hollow plunger rod H, to be l discharged at the upper end thereof bythe valve Hopening into the tubing B. Now, it will be seen that the liquor in the barrel D is transferred to the tubing B Without passing through the packing cylinder D2, and grit or other impurities are prevented from entering the said packing cylinder, either from above or below, as the stuffing boxes D and D3 and the plunger rod H are well packed. It is understood that on the up-stroke of the plunger rod H, the valves H2 and H3 close, so that the liquor is drawn into the barrel D, as above described.
As no grit can pass between the plunger and the bearing surfaces thereof, the Wear of the said plunger is reduced to a minimum and consequently the pump is not liable to easily get out of order.
The valve casing G may be removed for cleaning or repairing it, by bringing the plunger H down to an engagement with the boss Gthen turning the plunger to screw it down on the said boss, and thereupon Withdrawing the plunger with the valve casing.
Having thus described my invention, I claim as new and desire to secure by Letters Patentf l The combination, with the pump barrel, the packing cylinder located at one end thereof, and the plunger adapted to reciprocate in the said barrel and packing cylinder, of a stuffing box located at each end of the packing cylinder and adapted to engage the plunger, said stuiing boxes projecting outwardly beyond the packing cylinder to engage the pump casing, a packing held in the said cylinder at each end thereof, and a spring coiled in the cylinder and arranged between the said packings to press them into contact with the plunger, substantially as described.
ADAM ROSENKRANZ.
