PUiVlFlNG APPARATUS FOR WELLS.

SPECIFICATION forming part of Letters Eatent No. 696,616, dated April 1, 19012. Application filed April ll, 1901. Serial No. 55,380. (No model.)

To @ZZ whom it may concern.'

Be itknown that LBENJAMIN WINKLEMAN, a citizen of the United States, residing at Herring, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Pumping Apparatus for Wells; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to pumping apparatus for oil, water, and gas wells; and the object thereof is to provide a simple, durable, and efficient apparatus of this character in which the standing valve is so mounted as to be positively withdrawn with the working parts when the apparatus is removed from the Well, so as to avoid all liability of said valve being left in the bottom of the well when said parts are withdrawn.

To this end the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, Figure 1 is a side elevation of apumping apparatus embodying my invention, and Fig. 2 is a vertical longitudinal section of the same.

Referring now more particularly' to the drawings, the numeral l represents the standing valve, comprising a tubular casing 2, having an external packing 3 to tightly lit the well-tubing at the bottom of the well. At its upper end this casing 2 is threaded to receive the lower end of the valve-cage 4, between which and the upper end ofthe casing is clamped a flanged tube or thimble 5, having its upper end properly concaved to form a seat for a ball-valve 6. The standing valve remains stationary, as usual, in the bottom of the well, and the valve 6 opens and closes under the action of the working parts of the pump to allow oil to pass upwardly into the well-tubing and then closes to prevent the oil from passing backward again. When the pump is not in operation, the valve 6 is also adapted to be unseated by the upward flow of oil through the standing-valve casing 2 from the oil-bearing strata to allow it to enter the well-tubing, and then said valve closes in the manner stated to retain the oil in the tubing.

To the valve-cage 4. is secured the lower end of a rod or. tube 6', which projects upwardly therefrom and is provided at its upper end with an inverted-cone-shaped head 7. Working on and guided by said rod is a valved piston 8, which is coupled at its lower end by means of a coupling-collar 9 to a tube.

10, about which are arranged a series of packing-disks 11 to bear upon the inner surface of the well-tubing and form a liquid-tight connection between the same and the lower end of the barrel. At its lower end the tube or pipe 10 is threaded to receive a cap or cage 12, which is provided with a series of ports or openings 13 for the inlet of oil or other fluid being pumped into the said tube 10 and from thence into the barrel S.

The valved piston 8 is connected at its upper end by means of a screw-threaded coupling 13/ to a cage 14., which is provided at its upper end with a threaded stem or projection 15 for the attachment of the pump-rod or operating mechanism. Olamped between the coupling 13' and cage le is a ianged thimble or tube 16, which is concaved at its upper end to form a seat for the valve 17.

The screw-threaded coupling 13 has an opening of a smaller diameter than the head 7 on the tube 6', whereby when a downward stroke ofthe working barrel 8 is made the said head 7 coacts with the lower peripheral edge portion of the coupling 13 for the purpose of forcing the oil through the parts of the valve-cage 14.

The tube 10 is rigidly connected to the upper portion of the rigid collar 9 in such manner that its upper surrounding surface will be' below the upper surrounding surface of the collar, thereby utilizing said tube and collar, thereby forming a shoulder 1S,.Where by when the inverted-cone-shaped head 7 on the upper end ofthe rod 6 coacts with said shoulder, and likewise coacts with said tube 10, a connection is made for the purpose of removing the standing valve from the well.

The operation is as follows: The working barrel S and connected parts are reciprocated through the action of the pumping mechanism on the rod 6, and under the action there- IOO- of the oil contained within the well-tubing and passing upward through the valve 6 is drawn into the cap 12, tube l0, and barrel 8, and thence passes up through the latter into the valve-cage 14 and discharges through the ports therein. The stroke of the valved piston is limited to the distance between the upper end of the standing-valve cage and the head '7,and in its upward movement the valve 6 opens to allow oil to pass upwardly through the standing valve to the well-tubing above, and upon the downward movement of the valved piston said valve closes in an obvious manner. The rod 6 serves as a guide to maintain the parts of the apparatus in proper alinement and prevents wabbling thereof and at the same time aifordsa positive connection between the valved piston and standing valve to insure the removal ot' the latter from the well when the barrel is withdrawn. By this construction all liability of the standing valve being left in the bottom of the well-tubing, which is a common occurrence with pumping devices of ordinary construction, is avoided andA much valuable time and labor saved in the withdrawal of the pumping apparatus from the well.

From the foregoing description, taken in connection with the accompanying drawings, the construction, mode of operation, and advantages of the invention will be readily understood, and it will be seen that it provides an apparatus which is equally well adapted for water and gas as well as oil wells and which is simple in construction, is designed to act in an effective manner, and to provide for the proper removal of the standing valve simultaneously with the working parts of the device.

While the preferred embodiment of the invention is herein disclosed, it will of course be understood that changes in the form, proportion, and minor details of construction may be made within theV scope of the invention without departing from the principle or sacrificing any of the advantages thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a pumping apparatus for wells, the combination with the valve-piston having at its upper end a tubular coupling, a valve-cage with ports connected to the coupling above the piston, a anged tube clamped between the coupling and cage, a tubular collar rigidly connected to the lower end of the piston, a tube rigidly connected at its upper end to the collar, a cage connected tothe lower end of the tube, a shoulder formed at the intersection of the tube and collar at the upper extremities thereof and a standing valve, of a rod connected at its lower end to the standing valve, its upper end having a coneshaped head of a larger diameter than the opening in the collar connected to the upper end of the piston, said head coacting-With said opening of the collar, when an upward-and-downward stroke of the piston is made, said head also adapted to coact with said shoulder for the purpose of removing the standing valve from the well, substantially as specified.

In testimony whereof I have hereunto set my hand in presence'of two subscribing witnesses.
