PUMP.
Application filed August 11, 1924,- Serial No. 731,512. -Renewed September is, 1925.
To all whom it may concern: 1
Be it known that I, OSMYN Mownns, a citizen of the United States, residing at Houston, Harris County, Texas, have invented a certain new and useful Improve- Y ment in Pumps, of which the following is a specification. v
My lnvention relates to an 1mprovement in pumps and has particular application to plungers, or suckers, to be-used in recipro cating pumps employed in pumping oil or water from deep wells.
An object of my invention is to provide a plunger for deep well pumps which will be adapted for working in all kinds of tubing without the necessity of the usual work- I ing barrel.
Another object is to provide a plunger of this kind wherein the stream of fluid being pumped will pass largely outside of the plunger and between thesame and the tubing thereby largely avoiding the difliculty of the clogging of the plunger valve.-
Another object is to provide a cup in connection with this type of pump plunger which will be'collapsible and so supported as to prevent too great expansion of the cup on the upward stroke. 'These and other objects and advantages will be brought out with greater 'clearness in the specification which follows:
Referring to the drawing herewith wherein like numerals of reference are employed throughout both views to designate like parts; Fig 1 is a longitudinal section through a length of tubing showing my type of plungerxemployedtherein, said plunger being in elevation. Fig. 2is a central longitudinal section through a pump plunger employing myinvention.
This invention is an plunger disclosed in my prior application No. 418,899, filed October 23, 1920. This ,type of plunger maybe, and usually is employedin a sort of tandem arrangement, there bein a plurality of plungers upon the sucker rod positioned at intervals along the rod. In Fig. 1, I have indicated such an arrangement. Inthis view the tubing 1 is intended to represent any ordinary type of tubing and it will be noted that no special 'vorking barrel is necessary. The plungers designated by the numeral 2"are coupled I into an ordinary string of sucker rod 3, such ordinary solid sucker rod.
improvement on the accordance with the structure shown in Fig. 2. The central head of this plunger comprises a section of tubular pipe 4 threaded at its upper end for coupling within an The lower end at 5 1s also similarly threaded for attachment within a'coupling member 6. This lengtheof pipe is of uniform diameter and. has 1ntermediate the ends thereof a circumferential flange 7. This flange isformed by shrinking upon the pipe a metal ring of the same material as the pipe. The passage 8 through the head 4 is enlarged at a point about even with the flange 7 to form a valve seat 9 'to accommodate a ball valve 10 adaptedtofseat therein. Within the enlarged upper portion of the passage, through the tubing I fix'a pin 11, diametrically across the I pipe to limit the upward movement of the ball valve. At'a point immediately above the valve I form a plurality of radial open-- ings 12 to allow the passage ofliquid therethrough.
The coupling 6, to which the lower end of the pipe 4 is connected, is formed into an outwardly flaring cup 13 towards the upper end, but below the cup 13 it is reduced, in
diameter at 14 and has at the lower end an internallp threaded socket 15 for coupling within t sucker rod. At the lower end of the threaded socket into which the threaded end 5 of the head is attached, I form radial openings 16, allowing the passage of fluid inwardly to a chamber 17 connected with the lower end of the said head 4. Within the cup-shaped upper end of the cou ling there is formed a shoulder 18 agalnst which the lower end of a flexible cup 19 is adapted to seat. v.
The cup 19 forms the suction member of my plunger. It may be made up of any flexible wear resisting material such as rubber or various compositions. It is frusto conical in shape, having the lower end" 20 formed to fit within the support formed by the coupling 13 and has intermediate the ends thereof, an interior shoulder 21 adapted to contact with the lower face of the ring 7. The internal diameter of the cup is enlarged for that purpose to a point somewhat above the ring and then is flared outwardly at 22 to form. a suction lnemberf The outer face of the cup is inclined outwardly toward the upper end and has at a point immediately above the support 13 a shoulder 23.
It will be noted that the cup 19 is formed of such thickness that it will largely suppo} tits load of fluid without much assistance. I have provided, however, the support formed by the outer rigid cup 13 extending to a point somewhat above the middle portion of the sucker. The upper end is flared outwardly above the support so that it will contact lightly with the interior face of the tubing. On the down:
ward stroke of the plunger the cup will be allowed to collapse. suflicient to allow the fluid being'pumped to pass upwardly outside of the cup and the larger part of the I I a tight fit therewith.
. ward stroke When the plunger is used in fluid containing quantities of sand or other sediment, the upper'end of the cup tends to become clogged with the sand settling back therein. It is to avoid this clogging of the cu withsand, thata small portion of the fluid isallowed to find a passage upwardly through the plunger. Thus on the downa small stream of the fluid will flow inwardly through "the opening 16 into the passage 8 within the pipe 4 and will. raise the valve from its seat and allow this liquid to be forced outwardly through the openings 12 and upwardly through the upper end of the cup, thus carrying the sand in suspension with it to the surface.
In the assembling. of this device theflexible cup 19 is seated 'withinthe upper end of the coupling. downwardly into the cup and screwed within the said coupling. When the parts are thus tightened together the ring 7 will 'clamp the lower end of the cup between the shoulders 21 and 18, thus holding the cup securely in position. It will be obvious however, that thecup may be quickly removed when necessity arises by simply unscrewing and withdrawing the length of p It has been found in practice that a plunger thus formed will work for comparatively long periods of time without mate'- rial wear upon the cup. The manner in which this cup may be expanded by the weight of the load of fluid above it, makes a tight fit assured on the working stroke of the plunger. The strength of the cu itself reinforced by the outer cup 13 wi I prevent undue expansion. The contact of. the shoulder 23 of the cup with the cup 13 will limit the backward expansion of the sucker. The device is thus strong incenstruction and will wear for unusually .long
6 and the pipe 44 is inserted periods of time before replacementis necessary.
Having thus described my invention, the further objects and advantages of which will be clear to one skilled in the art; what 7 ed to fit within said coupling and between the same and said flange, and an outer shoulder on said flexible-cup fitting over the whereby said flexible cup is supported laterally cleared ofisand;

In.-a pump, a pump barrel, a reciprocable sucker rod therein, a tubular head connectedin said rod, a cup-shaped coupling connected to :said head,; an upwardly 95 flaring sucker otflexible material'se'ated in said coupling and supported thereby, said cup adapted to collapse on the. downward stroke and expand against said; pump barrel on the upward stroke, a shoulder on the thereinto receive the.lower end 7 upper end of said coupling said head being constructed head is detachably. engaged, an
and a central vvalx're controlled passa e through said head whereby said-cup may e outer face of said sucker adapted to rest on" said coupling'and means on said head to clamp against said sucker in the manner described.
4. In a pump, a pump barrel, a reciprocable sucker rod therein, a cup-shaped sucker of flexible material mounted thereon,
a cup-shaped couplingon said rod at the' lower end of said suckernto support the same, means on said sucker cooperating with said support to prevent undue expansion thereof, said sucker being adapted to collapse on -the downward stroke .to allow pas sage outside' thereof vfor the' fluid being pumped.
'5. p In a pump, a pump barrel, a sucker rod r'ecipr'ocable therein, a tubular head connected said rod, a cup-shaped coupling towhich said head is engaged, an upwardly flaring sucker of flexible material sup orted in said coupling and held clamped t erein by said head, said coupling having lateral passages therein connecting with said tubular head, and said head having outlet passages within said sucker whereby said sucker may be flushed free of sand.
In testimony whereof I hereunto affix my signature this 2nd day of August, A. I). 1924.
