W. M. STEPHENSON OIL SAVER DEVICE Filed Oct. 25, `1917 l HHH flat-eluted llllay' l, lilith at lallas,

from l usable for a ject of my in and improved oil well which ol'wiates the above named faults of present oil well pumping machinery, which and which functions to prevent the soil surrounding; the cil wells from being saturated `with waste oil., to the end that the vegetation is not destroyed, and to the further end that the soil be used for agricultural purposes after the oil well has been exhausted and the soil returned to agricultural eiiterprises.

'lhese desirable purposes are accomplished by einualoying` a simple form of receiving` the well casing et and oil delivery or work- 5 extends downwardly to the source of oil supply, where on the delivery pipe 5 there is usually known as equipped with a andnot shown Ain not a part of the pipe or working` well.

Be it known that l, llll'iimiaiu lli/l. Sl'rniifriiuson, a citizen of the United lsltat s `(,:ountyf of Dallas, and Texas, have invented a new and useful (lilfdaver Device, of which the following' a sijiecificatioii.

principal objects and others in view, the invention has relation to a certain construction and combination of parts, an example of which is described in specification, defined in the appended claims, and portrayed in the accompanying drawing, wherein:

sectional view El illustratin sectional disclosure invention. A sucker rod G is confined in the oil delivery pipe 5 and connects at the bot-- tom of the Well, with the piston in the aforesaid working barrel. rllhus the sucker rod 6 is employed to successively reciprocate the pump at the bottom of the well and lift the oil through the delivery pipe 5, where it is discharged at the surface ofthe earth through any suitable distributing` pipe. In typical well pumping equipment, there is most always used a stuffing boi; not shown herein, on the upper end of the oil delivery pipe 5, and the sucker rod 6 passesthrough this stuffing box and connects withan engine or steam head superimposed above the head of the casing 1. `vThe constant reciprocating motion of the sucker yrod 6 t irough the stutling box causes leakage of the oil from the delivery pipe vout through the stuffing boX, and this vleakage is constant and prevalent on all oldty'pes of oil well pumping lequipment generally usedI in the `'oil fields. 'i

The foregoing paragraph sets forth a synopsis of the construction and operation of a typical well. The loss of oil is so constant that in the course of the life of one well, there are many barrels of oil lost through the 4'small leakage past the stuffing box vdue to the fact ythat no means is provided for catchingthe oil which is squirted ,out and lost through the old stutling bo);

'upon each upward stroke of the sucker rod. The conception land reduction to practice of this invention contemplates theuse of a receptacle to house and enclose the stuffing lbox and other parts to eliminate the necessity of the stufling boX and to receive all the oil which llows upwardly from the delivery pipe.

An oil saver receiving chamber 7 is preferably constructed ina single piece iron casting, and made in the form of an elongated Vhousing which may be either cylindrical or rectangular in cross section. This receiving chamber or receptacle 7 is formed lwith an integral flange 8 at each end thereof, and each end of the receptacle is preferably vleft open so that the sucker rod may be inserted from the lower end of the receptacle and asteam head may be mounted on the upper end thereof. The bottom flange 87is anchored to thewell cap 9 which secures the .receptacle in concentric position `over the well casing 1. One side of the receptacle 7 is provided with an enlarged inspection opening which is closed by a cover plate 11. This' construction provides a solid closed oil receptacle with a cover plate 11 which may be removedjforlinspection, assembly, or repair of parts `within the receptacle. This receptacle Tis made of such suitable length as to adequately -function as a baseer stand upon which ismounted a `steam head or any suitable type of motor for working the sucker roc.

fr discharge pipe line 12 connected with the receptacle '7 for the purpose of conveying oil therefrom as it is forced upwardly from the delivery pipe This discharge pipe 12 is connected to the receptacle 7 at a point suitably located ai'ljacent the bottom end of the receptacle in order that the oil will not rise to any considerable height within the receptacle. The discharge pipe 12 leads from the well to any suitable place of storage. lt is to be noted that in the assembly of this equipment both the delivery pipe 5 andthe discharge pipe 1Q open directly into the receptacle 7, and neither of these pipes is fitted with a stufling hex. In this manner oil flows freely out the top of the delivery pipe 5 into the receptacle 7,

whereupon it flows from the receptacle i outwardly through the discharge pipe 12.

lThe receptacle is employed as a hase or support, and on the upper end thereof, there is mounted a steam head or any other suitable type of engine or motor employed for the purpose of operatingl the pump. lu the drawings, there is shown one universally used type of steam head 11 having a piston 15 and connecting rod '16. The connecting rod projects downwardly through a stuifing box casing 17 which has a pressure nut 18 for taking up wear in the stalling box. The connecting rod 16 is conlined in the receptacle 7 and joined to the sucker rod 6 through any suitable joint or connection 19. T he connecting rod 16 reciprocatcs through the stutling box 17, and both this stuffing box and the connecting rod joint 1) may he inspected and hept in working order through access thereto vby the removal of the cover cap 11.

The above paragraph sets forth an approved source of motive power, in the 'l'orm of a vertical single stroke engine. to drive a pump in an oil well. Before the use of my invention, it was necessary to employ a frame or legs to support the engine or steam head 1-,t directly over the well easing. ln the use and practice of my invention` the re ceptacle T supplantsthe use of the old steam head supporting` frame, and likewise performs the purpose of an oil saver receptacle to eliminate the use of the old stufling box.

ln the operation of an oil well pumping equipment embodying my invention` the steam headi 14 is started in operation by opening the throttle or valve used to control the engine. The'oil tlowsfrom the delivery pipe 5 upwardly into the chamber T and out through the discharge pipe 12. In the ah sence of a stuling box at the top of the pipe 5 and around the sucker rod G, the oil flows quite freely into the receptacle. The pressure of the steam in the cylinder of the en- Sil lue

Lli)

raeasos gine 14 prevents the oil from entering the cylinder., but sutlicient oil is present to lubricate the piston and rod of the engine which obviiates the necessity oii` oiling these parts. '.llhe receptacle being" a closed housing` or container, contines the oil,y therein until it has 'flowed out through, the discharge pipe l2. `lnasmuch as the receptacle i' completely i-ancloses the head and upper extremity ot the delivery pipe 5, there is no egess or opportunity `whatsoever for oil to be lost by leakage or seepage from. the delivery pipe into the ground, but on the other hand all the oil is confined within the receptacle 7 and caused to :tiow trom the weil out through the discharge pipe l2.

'.lhus the invention ieaturesthe simple receptacle 'acting the double part ot an engine support pedestal or base, and a receptacle or well seal to receive and distribute the oil tothe discharge pipe, whereby is eliminatedthe waste of oil and consequent saturation oi the earth surroui'iding the well to the end that economy and etlieiency characterizes the operation ot an oil well operated under the plan ot my invention.
