PUMPING APPARATUS FOR OIL-WELLS.

Application filed February 2, 1907.

Specification of Letters Patent.

Patented May 19, 1908.

Serial No. 355,479.

To all Iwhom it may concern:

Be it known that l, GEORGE L. OUsAo, a citizen of the United States, residing at Findlay, in the county of Hancock and State of Ohio, have invented certain new and useful Improvements in Pumping Apparatus for Oil-/Vells, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in pumping apparatus for oil wells.

The object of my invention is to provide a pump of the character described, in which the standing valve and the piston are so arranged and connected together that they can be raised together so that either or both of them may be repacked when necessary.

Another object of my invention is te provide a sleeve or jar, of such a structure to prevent friction, and in which the paraffin will not clog or otherwise affect the working of the pump valves, and the said sleeve or jar being so arranged as to jar the paraflin from around the valves and allow them to seat themselves at all times, thus preventing any back pressure and assuring a steady flow of oil from the well.

A still further object of my invention is to provide a simple, cheap and effective pump constructed of fewer parts than other pumps of this character, and adapted to more effect* ively accomplish the desired results.

In the accompanying drawings, Figure 1, is a vertical sectional view of a working barrel of an oil well showing the pump in perspective. Fig. 2, is a vertical sectional view of the working barrel showing the pump in section.

^ Referring now to the drawings, 1 represents the working barrel of an oil well, all of which is well understood by those skilled in the art, and needs no further description. ln oil wells of this character the standing valve is usually placed within the lower end of the barrel and carried, or frictionally carried thereby, and the piston valve is within the barrel thereabove, and working within the barrel. 2 represents my improved pump which, as shown, is composed of a sleeve or jar 3 of an elongated form, and having its lower end of a contracted solid form, as indicated at 4, and said contracted portion has an opening 5 therethrough. The said sleeve is provided with the elongated slots 6 entirely surrounding the sleeve, and arranged in two series. The said sleeve, as before stated, is of an elongated form and the upper en thereof is internally screw-threaded at 7 and into which the externally screw-threaded portion 8 of the sleeve 9 is screwed. The said sleeve is of an elongated form, and adjacent the upper end thereof is provided with an outwardly-extending 'flange 10 which is provided with a beveled lower face 11. Mounted upon the sleeve between the flange 10 and the upper end of the sleeve 3 are the packing rings 12 and 13 which form a tight joint with the inner face of the working barrel 1. The packing rings 13 are of leather or other librous material, and between each of said packing rings are the metal rings 12 which are provided with beveled lower and outer faces 14, and the packings 11 are forced upwardly upon the beveled face 14 and are expanded outwardly by the pressure of the straight wall 15 of the rings 12, being forced upward by screwing the sleeve S into the upper end of the sleeve 3, and whereby all of the leather washers are expanded outward.

The sleeve 9 above the `[lange 1() is externally screw-threaded at 16, and screwe thereupon is the valve casing 17. The said casing, as shown, is provided with an enlarged screw-threaded portion 1S which screws u on the screw-threaded portion 16 of the s eeve S), and resting .against the shoulder 19 formed'by said enlarged screwthreaded portion 1S is a flange 20 of the valve seat 21, thus making the valve seat remov able so that it can be readily replaced when it becomes worn. The upper end of the valve casing 17 is contracted and has an externally screw-threaded portion 22 upon which is screwed the sucker or o erating rod 23 which extends upwardly t rough the casing and at the upper end is provided with any desired operating mechanism, as will be hereinafter more fully described.

The valve casing 17 is provided with the slots 24 through which the oil passes in its upward movement. l/Vithin said casing is the usual ball valve 25 which is of a size to fit upon the valve seat 21, but large enough, or the slots 24 small enough to prevent the yrod 26 and the standing valve 30 is made so sasie the ball 25 and passes upwardly above the piston where it is lifted up, by the upward movement of the piston, as scribed.

The elongated sleeve 3 reduces the friction and forms a jar for shaking or jarring the valves to prevent the paraflin from gathering on the valve seat, and thus always insuring of a perfect seating of thevalves, and the openings 6 in the sleeve, being of the form shown, the parafn can not possibly clog the openings, and thus the valves are always in working order, and the pump can be continuously worked.

Connected to the bottom of the barrel 1 is va short piece of perforated pipe 36 which does not quite reach the bottom of the well, and through these perforations the oil passes to the standing valve.

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

1. In an oil pump, the combination with a working barrel, of a standing valve snugly fitting the lower end of the barrel, a sleeveor jar within the casing above the standing valve and having a contracted lower end having an opening therein, a rod slidably mounted in the sleeve and having a head therein to prevent it from passing therefrom, the lower end of the said rod having a screw-threaded portion screwed into an opening in the standing valve, a lock-nut on said rod above the standing valve, said sleeve or jar having elongated slots communicating with the interior thereof, the upper end of said sleeve internally screw-threaded, a sleeve of a diameter equal to the interior of the sleeve or jar, and having its lower end screwed into the sleeve, an outwardly extending flange formed integral with the upper end of the sleeve, fabric and metal washers alternately arranged on valve from passing out of the casing, yet allowing it to readily move up and down within the casing.

Passing through the opening 5 in the lower end of the sleeve 3 is the connecting and guide rod 26 which is provided at its upper end with'the headed portion 27 which prevents the rod from passing out through the opening 5, whereby the working valve and iston may be connected, so that they may both be removed together, as will be hereinafter more fully described. l

The lower end of the said connecting rod 26 is screw-threaded at 28 and screwed within an opening 29 in the upper end of the standing valve casing 30. The said standing valve casing is of the usual form, having the ball valve 31, the removable seat 32, the removable sleeve 33 carrying the packing 34, all of which are constructed and arranged to perform the function as is understood by those skilled in the art.

The connecting rod 26 upon the screwthreaded portion 28 thereofabove the valve casing 30, is provided with a lock nut 35 by means of which the connection between the that it can not be accidentally disconnected.A during the reciprocation, or caused by the reciprocation of the piston. i

y the construction herein shown and described, it will be seen that the piston valve and standing valve are connected together, and that in order to replace any part of either valve, or both, t e one operation of raising is all that is necessary.

The operation is as follows :-The parts being put together, as shown, the apparatus is forced into the well tubing 1 until the standard valve is near or at the bottom of the working barrel. The friction of the packing 34 of the standing valve 3() will be sufficient to hold it in its downward position, and the reciprocation of the rod 23 causes the piston to move up and down within the casing. The parts being in osition shown in the gures, the oil comp etely fills the tubing from the standing valve to the u per end thereof'. The upward movement o the piston, as heretofore described, causes the ball 25, by the oil thereabove, to firmly seat itself, and the packing 13 forms a tight joint with the working barrel, lifting the oil above the same, while at the same time the suction below the acking lifts the ball 3l and causes the oil to ow upward through the openings in the valve 30, and iill the space between said standing valve and the piston valve. The downward movement of the piston valve sleeve causes the ball 31 to seat itself and the oil above the said valve is forced inwardlyy through elongated openings in the sleeve or jar 9, out through the sleeve 9 and unseats end of the sleeve or jar, and the metal washers so arranged and constructed to expand the fabric washers outwardly upon screwing the sleeve in the far, the upper end of the sleeve above the flange having an externally screw threaded portion, a valve casing screwed on said screw-threaded portion of the sleeve, a valve wit said casing, and means carried by the upper end of the valve casing for securing the pump rod thereto.

2. In an oil pump, the combination with a working barrel, of a standing valve fitted in the lower end of the barrel, a piston within the barrel above the standing valve, a sleeve carried by the lower end of the piston and holding the valve and valve-seat in position and having an outwardly-extending shoulder adjacent its upper end, packing carried by the sleeve below the shoulder, an elongated sleeve and expanding the sleeve between the flange and the upperv heretofore dethe packing between it and the shoulder, said headed end of the rod prevents the wax from 10 jar having a contracted lower end having an gathering in the slots.

In testimony whereof I affix Iny signature opening, a rod secured to the standing valve and passing through the opening in the jar, in presence of two witnesses. and having a headed upper end within the GEORGE L @USAC jar, and said jar having elongated vertical slots extending approximately Jfrom the upper to the lower end of the jar and arranged around its entire periphery, whereby the Witnesses:

WILLIAM L. DAVID, JOHN E. FENNERTY.
