PUMP.

v Application filed October 23, 1920. Serial No. 418,889.

To all whom it may concern:

Be it known that I, OsMYN MownRs, a citizen of the United States, residing at Houston, Harris County, Texas, have invented a certain new and useful Improvement in Pumps, of which the following is a, full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to an improvement in means for pumping oil, water or other fluids from wells of any depth. It is especially adapted for use in the pumping of .lieiuid s containing quantities of sand or iment, which ordinarily tends to wear both the pump barrel and the plunger.

An object of my invention is to provide a device for raising liquids from the .well, which, because of its action, will be exposed to a minimum amount of wear and which will work for long periods of time without the necessity of removal of the working parts. a

Another object is to provide a device of this character which will operate in the ordinary pump tubing without the necessity of supplying speclal working barrels in which to operate.

Another object is to device which will automatically clear itself of sand or similar material and thereby avoid clogging of the parts.

Other objects and advantages will appear in the specification which follows and the points of novelty thereof will be referred to with more particularity in the claims.

Referring to the drawin herewith, in which like numerals of re erence are applied to like parts in both the views, Fi 1 1s a central longitudinal section throug a well casing and tubing showing my improved pumping device inoperative position therein. Fig. 2 is a central longitudinal section, on an enlarged scale, of one of the cups used with my invention.

In the ordinary type of pump employed in pumping Wells, it is customer to provide a plunger having a close fit wit the working barrel of the pump and it is also custoinato rovide a s ecial t e of workin bar rgl ma de of harde iied met eil to withstand the wear occasioned by the reciprocation of the plunger. lln the operation of my device, however, I contemplate using the ordinary tubing which" forms the upper portion of provide a pumpingrel when my device is employed. In Fig. 1 Y

I have shown a tubing 1, as being inserted downwardly within the casing 2 of a deep well. The tubing 1 is closed at the lower end, there being an opening 3 in the said closure, this opening being normally closed by means of a valve4 of any ordinary construction, this valve being adapted to open upwardly in the usual manner.

The lifting device employed for raising the fluid within the tubing 1 is of special construction. I contemplate employing a plurality of frusto-conical shaped cups 5, said cups being connected at spaced intervals along an ordinary solid su'cker rod 6 of the usual construction. It is possible, of course, in shallow wells to use but one of these cups 5, but in deep wells it will be preferable to use a plurality of them, each cup being spaced from the other by a suitable distance, which maybe anywhere from about twenty-five to one liundred feet apart.

In Fig. 2 I have shown a more detailed view of the construction of the cups 5 and pump rod. The cup 5 is mounted upon a section of pipe 7, threaded at its lower end at 8 for connection with a length of sucker rod and having the upper portion of the said pipe counterbored for about half its length and threaded interiorly at'the upper point 9 thereof for attachment to the adjacent length of sucker rod 10. The cup 5 is secured intermediate the ends of the pipe section 7 the smaller end of thecup being presented downwardly and attached firmly about the pipe? and retained in position by means of diametrical rivets 11, or any other preferable means, the object being tohold the cups in fluid-tight relation to the pipe. This cup 5 may be formedof leather, rubher, or any flexible wear-resisting material. The upper and larger end of the cup, in its ordinary, osition, is slightly smaller in diameter t an is the inner diameter of the tubing 1. It is retained in itsupright pesition, so that it may not be forced to double backwardly, by means pf a'series of connecting-- braces 12, of which I ordinarily employ four in number. These braces 12may be made of strips of sheet iron or steel, secured at their upper ends to a; slidin col-= lar 13. This collar is hmited in its ownllO ward movement by means of a ring 14 which is shrunk securely upon the outer surface of the pipe 5 at such a point as to prevent the downward movement of the collar 13 beyond the point where the outer upper edge- 15 of the cup contacts with the inner surface of the tubing 1. At the lower end of the counter-bore portion of the pip eh7, I form a seat 16 for a ball valve 17. is seat 16 is intended to 'be removable and may be made of brass, bronze or any other suitable material. 7

The pipe 7 is perforated below the cup 5 at 18 to allow the entrance ofsome of the fluid being pumped into the inner channel of the pipe. Above the valve seat 16, and within the cup 5, are a plurality of openin 19 to allow an outlet for the fluid insi e the cup. Above these openings 19 is a cross pin 20 adapted to limit the u ward movement of the ball valve 17 in an o vious manner.

The operation of my .device is as follows: On the upward stroke of the pumprod, the foot valve 4 at the lower end of the tubing willbe raised by the action of the cups 5, dra into the tubin 1' a charge of fluid.

' The cups on the upwar stroke-will be forced I the tubing.

outwardly against the inner face of the tubing 1 by the head of fluid already within the outer edge 15 of the cu 1s thus thrown against the tubing the s11 ring 13 will be drawn downwardly and will contact with and be prevented'from further movement by the ring 14. The valve 17 w1ll be held within its seat 16 and the fluid above the cup will be. raised within the tubing.

On the downward stroke of the sucker rod, the foot valve 4 will be closed and the fluid within the tubing will be forced upwardly past the cups 5. The cups will hence be contracted so as to allow-the assage of watenaround the outpr margin oi the on s, the shdmg ring 13 will be forced upwar ly and the ressure of the water within the tubing W111. force a .flow inwardly through the openings 18 and will raise the valve 17 off its seat and allow the passa e of fluid out through the openings 19 am? upwardly inside the cu The parts will then be in thegiosition s own in Fig. 2. This flow of flui through the pipe 7 will carry any sand or dirt upwardiy away from thecup and prevent its lodging therein, thus preventing the clogging o the cup and leaving it free too erate at all times.

e use of a series of these cups along the sucker rod is valuable for the reason that a better liftin action is obtained thereby, and because t e head of water standing wlthm the tubing will not all rest upon the lower plunger, as is usually the case. The cup Wlll have to support only the head of water between it and the next upper adjareason the usual amount of wear will the outer edge 15 of the cup willonly' be in contact with the tubing on its upward stroke and that on its downward strokethe sediment which might tend to collect about the outer edge thereof will .be drawn upwardly the current of fluid. On the upward stroke of the plunger, the sediment Wlll not have an opportunity to collect materially between the cup and the tubing and for tliis e greatly minimized. Wells equipped with this device have been found to operate much longer before repair is necessary than is the case with the usual type of plunger.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:
