JOHN PENROD, OF BEGGS, 4AIN' D ROBERT D. THOMPSON, OF OKMULGEE, 0KLAH01V[A OIL' 'WELL intenso.

Application led November 1 0, 1920. Serial No. 423,082.

To all who/m, t may concern:

Be it known that we, JOHN PENROD and ROBERT D. THOMPSON, citizens 'of the United States, residing at Beggs and Okmulgee, in the county of Okmulgee, State of Oklahoma, have invented a new and useful Oil lVell, of which the followingis a specification.

This invention relates to oil well pumps, it being the object of the invention to provide a plunger of a novel construction designed to eliminate sand or gravel passing upwardly through the valves of the pump.

A further object of the invention is to provide a pump of this character including a sand pocket to receive the sand or gravel, and direct 'the same to? the well.

A still further object of the invention is to provide a clutch mechanism for automatically clutching the pump rod to the sucker heads of the pump, the clutch being designed-to automatically release the pump rod, when the pump rod has been moved to a predetermined position.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement ofl parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed,amay be made within the-scope of what is claimed, without departing from the spirit of the invention.

eferring to the drawings Figure 1 illustrates a vertical sectional view through the upper section of a working barrel, showing the pump rod and valve member clutched thereto. g

Figure 2 illustrates a vertical sectional view through a portion of the working barrel and valve adjacent to the structure as shown by Figure 1.

VFigure 3 illustrates a vertical sectional view through the lower section of the working barrel disclosingthe lower pump valve.

Figure 4 illustrates a vertical sectional view through the extreme lower` end of the working barrel.

Figure 5 illustrates a sectional view taken on line 55 of Figure 1. p

Figure 6 illustrates a sectional view taken on line 6 6 of Figure 1.

Figure 7 illustrates a sectional view takenon line 7 -7 of Figure 4.

Referring to the drawings in detail, the reference character ."5 designates the tubular Specification of Letters Patent. Patented i,

1 1, plunger'of the pump which is supported wlthm the working barrel 44 which is positioned in the outer casing 6, the lower extremlty of the casing having connection wlth the bushing 7 as by means of the threads 8, which bushing 7 also provides a support for the lower casing 8 which terminates 1n a bell bottom 9, which bell bottom provides the entrance to`the casing' 6 of the pump.

The bushing 7 also provides means of support for the tube 10 which is housed by the casing 8, the lower extremity of the tube 10 having connection with the intake pipe 11 which is provided with a plurality of ppenings 12 to admit fluid to the interior of the intake pipe 11, the intake pipe being positioned in the well. a

Supported within the tube 10 is a spacing sleeve 13 which is threaded interiorally to accommodate the removable valve ring 14 which is provided with a valve seat l5 de-v signed to accommodate the valve member 16 held in its operative position as by means of the valve spider 17, the valve member 16 being for the purpose of controlling the passage of fluid through the tube 18.

The tubev 18 extends upwardly within the tube 10, and is connected to the valve ring as 'by means of the securing sleeve 19. the upper end of the tube 18 being disposed within the bushing 7, at a point directly bewhereby fluid may pass upwardly between" the casing 8 and tube l() and into the pass'- ageway formed between the vacuum tube 18 and the tube 10.

At the upper end of the plunger 5 is supported the clutch head indicatedat 23, which has the clutch members 24 pivotally supported within the clutch head. the lower ends of the arms having connection with the clutch members 25, while the upper extremities thereof are normally forced outwardly by means of the coiled springs 26, the upper ends of the arms being however curved as at 27 to cooperate with the inclined wall 28 of the head 29. Fromthe foregoing itis obvious that as the clutch head is moved upthe inclined wall 28, the upper ends of the .arms are cammed inwardly causing the lower ends of the'arms t move the clutch members 25 out of the circumferential groove formed in the valve rod 31.

The valve rod is connected to the pump rod 32 as by means of the head 33 which is internally threaded to receive the threaded stem 34 of the valve stem, the lower portion of the nected to the upper portion ,as by .meansl of the threaded extension 35, the lower portion of the valve stem being however formed into a valve cage 36 to accommodate the ball valve 37,Twhich seats on the valve ,seat 38 and controls the passage of fluid into the upper portion of the casing. A

The lower valve stem 39 has connection with the lower valve cage 42 in which operatesthe valve 41, the cage carrying valve barrel 40 on the lower end thereof, which valve barrel is hollow and supports packing rings 41- on the periphery thereof to insure a fluid-tight connection between the valve barrel and the bushing 42', the bushing be- -ing shown as threaded. and having a cirbarrel 44.

.is vupon fluid is sucked through the bell bottom.

cumferential flange 43 to' connect the same Ato the plunger 5.v The valve barrel 24 is provided with a plurality of lopenings 43 to permit the plunger. p A ,4

The plunger 5 also moves' in they working barrel 44, there being'provided suitable packing 45 carried at the upper end of the barrel 44 for insuring a fluidtight connection between the plunger' 5 and the working In the operation of the device, the rod 32 reciprocated by any suitable means, lwhereof the casmgfS, where the same passes .up-

wardly, and isd'rawn through theopem'ngs f 22 and into the V'casing between the tube 10 and tube 18, twherethe same passes upwardly v over the upper end of tube 18 past the ball valve 2() and into the working barrel 44. It is obviou's that as the fluid passes to the upper end of the tube. 10, the sand or' gravel drops through the sand pocket or space formed between the tube 10 and tube 18, thereby eliminating any possibility of the valve members contacting with vthe sand to render, the same inoperative.

If itis desired to remove' the valves from the plunger 5 it ,is only necessary tomove therod 32 upwardly until the upper curved extremities of the arms 24 contact with the inner curved wall of the head 29, whereupon the clutch members 25 release their vhold on the valve rod 31 to v release the same, vthe plunger 5 together with the clutch members drops to a position to rest at the upper end of barrel 44. 4It follows that by further movement of the rod 32, the valve rod 3l together valve stem being separable and co'nJ purposes of repair. y

` From. the foregoing it will be seen'that owing to the fact that'the plunger 5 is of a l greater diameter than the ported thereabove, a greater displacement is insured to the end that a greater volume of fluid is forced through the tubing, at the same time the structure is such as to permit the valves to be removed for repair.

Having thus described the invention, what well tubing Ysupis claimed as new is l'1. In a device of the character a casing, a working barrel within a plunger within the working barrel, a pump rod extending into the plunger and carrying valves, means for clutchin the plunger to the 'pump rod, and meansvv or automatically disengaging the clutching meansn 2. In a device of the character\described, Ia casing, a working barrel within the casing, pivoted arms carried at the upper end of the plunger, 'a pum the plunger, sai ferentiall groove,
