OIL OR WATER PUMP.

Application filed February To all whomt't may. concern:

Be itknown that we, JOHN A. KNo'rTs and WILLIAM R. MoNEIoE, citizens of the United States, residing at Caney, in the county of Montgomery, btate of Kansas, have invented anew and usefulOil or Water Pump, of which the following isa specification. I

This invention relates to pump constructions, and more particularly to pumps em ployed in connection with oilwells or the like.

The primary object of the invention is to provide means for operating the ball valves of the pump construction, to mechanically unseat the same, thereby permitting the sediment or other foreign matter which may collect under the ball valve, to be washed from the seat thereof.

A further object of the invention is to provide a means for releasing the oil contained in the pump, when the tubing is being pulled, thereby eliminating any possibility of oil being removed during the pulling operation.

Vith the foregoingand other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention,

Referring to the drawing Figure 1 illustrates a longitudinal sectional view through a device constructed in accordance with the present invention.

Figure 2 illustrates a longitudinal sectional view through another portion of the device, the same being a continuation of the device shown in Figure 1, and

Figure 3 illustrates a sectional view though the lower portion of the device disclosing the arm for actuating the ball valve.

Referring to the drawing in detail, the reference character 5 designates the work ing barrel or pump tube in which the pump rod indicated by the reference character 6 operates, the pump rod being of a particular construction employed in pumping oil wells, the same being provided with working valves as shown by the reference character 7.

This pump rod extends through the casing 8, the lower extremity thereof being threaded as at 9 and positioned in the 10, 1921, Seria1 No. 444,060.

threaded opening of the housing 10, there being provided a circumferential shoulder indicated at 11 and formed integral with the threaded portion 9, for purposes tolbe hereinafter morefully described.

Positioned within the pump barrel at the lower extremity thereof, is the standing valve cage 12, which includes an upper section 13 and a lower section 14, the lower section having a threaded oonnectionwith the upper section 12, as at 15, suitable washers 16 being provided to prevent the fluid from passing between the valve cage, and inner surface of the pump barrel.

As shown, the upper portion 12 of the standing valve cage is cut away. to provide the valve chamber 17 adapted to accommodate the ball valve 19, which is normally seated on the valve seat 20in a manner to release the gases and air within the pump barrel, but prevent the fluid from running back into the well. I

The upper portion of the upper section 12 is reduced as at 21 to accommodate the movable ring 22, which ring. is held on the reduced portion as by means of the threaded ring 23, which cooperates with threads provided on the extreme upper end of the upper section so that the ring member 22 may be moved throughout the length of the reduced portion, the ring contacting with the lower edge of the ring 23, on its upward movement, and contacting with the shoulof its downward movement.

Secured to the ring 22, at its upper end, is an operating arm 25, which has its lower end curved inwardly as at26, and flattened as at 27, so that the same will ride over the surface of the ball valve 19, and seat under the ball valve so that upward movement of the ring 22 will move the ball valve from its seat, and permit the fluid supported by the ball valve to flow back into the well, and carry therewith, any sediment which may collect between the ball valve 19 and its seat.

The lowerextremity of the pump rod is also tapered as at 28, to conform to the tapered threaded opening 29 of the standing valve cage, so that the rod may be dropped into engagement with the valve cage, the lower edges of the housing 10 contacting with the ring 22 to cause the same to move downwardly accomplishing the unseating of valve 19.

ders 2-1 when the same has reached the limit,

If it is desired to remove the standing I valve cage, it is only necessary to position the tapered threaded portion 28 of the rod in the opening 29, whereupon the ball valve 19 is unseated to permit the fluid to flow back into the well. The pump rod may now be used to extract the standing valve cage.

Upon replacing the standing valve cage, the same is positioned on the threaded portion 28 and inserted in the well, the rod is now rotated in a manner to disconnect the valve rod and standing valve cage, the coiled spring 30, acting to'return the ring 22 to its normal position, and consequently permitting the ball valve 19 to seat, to accomplish the pumping operation. 7

Having thus described the invention, what is claimed as new is p In a deviceo-f the character described, a standing valve cage having a laterallydisposed opening, a valve seat in the valve cage, a ring member slidably' mounted on the upper end of the valve cage, a coiled spring contacting with the ring member for normally urging the ring member to the limit.

hold the same out of engagement with the valve seat. V w

In'testimony that we claim the foregoing as our own, we have hereto aiiixed our signatures in the presence-of two Witnesses.
