Application flied November 10, 1913. Serial No. 300,223.
To all whom it may concern:
Be it known that l, Crmnnns M. Mvnns, citizen of the United States, residing at Sperry, in the county of Tulsa and State 0t Oklahoma, have invented certain new and useful improvements in Valved Pistons, of \\hich the following is a specification, reference being had to the accompanying draw ings.
T his invention relates to valved pistons and more particularly to oil well valved pistons and has tor its primary ob]ect to provide improved means for preventing sand from moving upwardly in the well tube between the wall thereof and the piston body and collecting upon the valve seat.
The invention has for another and more particular object to provide a piston body or barrel, and means for easily and quickly mounting thereon a plurality of split pack ing rings or gaskets, which automatically take up wear and maintain a close trictional engagement with the wall oil the Well tube.
A further object of the invention is to generally improve and simplify the construction of devices of the above character, to increase their efficiency in general use and to minimize the expense incident to frequent repairs.
llith the above and other objects in view as will become apparent as the description proceeds, the invention consists in certain constructions, combinations and arrangements of the parts that .l shall hereinafter fully describe and claim.
For a full understanding oi the invention, reference is to be had to the following description and accompanying drawing, in whichliigure 1 is a side elevation of an oil well valved piston embodying the present invention in its preferred form; Fig. 2 is a longitudinal section thereof; Fig. 3 is a section taken on the line 3-3 of Fig. 2; Fig. 4 is a detail perspective view of one of the split packing rings or gaskets. Fig. 0 tional view of the packing ring.
listening in detail to the drawing, 5 designates the hollow metal body or barrel oi the valved piston having a reduced exteriorly threaded end 6. The opposite end of this barrel 5 has an annular shoulder 7 formed upon its periphery and is further 8 of greater The upper is a secdiameter than said shoulder.
' a split metal packing l end of the barrel 5 is exterior-1y threaded as i at l) and is provided with a seat 10 for a i valve ball 11 which is movable in a suitable cage 12 adapted to be threaded upon the exteriorly threaded end 9 of the barrel or body. The cage 12 is provided with the usual threaded stern 13 for the connection of the pump rod thereto.
l-l and'lfi designate short and long sleeves respectively which are adapted to be alternately arranged upon the tubular body or barrel 5. One of the short sleeves lrl is first fitted against the annular shoulder 7 of the barrel, and between the end out this sleeve and the annular flange 8 on the valve body, ring 16 is adapted to be arranged. This ring is diagonally split as indicated at 17, and its inherent resiliency normally maintains the spaced ends of the ring in separated relation. llhe lower end of each of the sleeves it and 15 is internally reduced in diameter as shown at 18, to receive a similar packing ring, which is ar ranged between the annular shoulder 19 thus formed on one end of each sleeve, andthe upper end of the next adjacent sleeve. The lowermost sleeve 20 is not provided with a reduced portion 18. This sleeve is held in place upon the lower end of the body or barrel 5 by means of a cylindrical cap 21 till which is adapted-to be threaded upon the reduced lower end 6 of the barrel. The annular body wallot this cap is perforated as indicated at 22 so that the oil may enter the same in the downward movement oi? the piston in the well tubing and pass upwardly through the barrel 5.
lit will be noted that by alternately arranging the long and short sleeves 15 and 14:, the metal packing rings are disposed in spaced pairs, a pair of such rings being centrally arranged upon the piston body and another pair located adjacent each end thereof. 'lhese rings normally are of slightly greater external diameter than the diameter of the sleeves lll and 15. The lower edge of each ring is beveled as shown at 23 so that the same will be compressed or the spaced ends thereof forced toward each other as the piston is inserted and forced downwardly in the well tubing.
From the foregoing, it is believed that the construction and mannerof operation of my invention will be clearly and fully understood. The metal packing rings may be easily and quickly arranged xupon the well tubing is automatically taken up by the inherent resiliency of the rings, there being a constant outward expansion of the spaced ends of the packing rings. These packing rings effectually prevent the sand being carried with the 011 upwardly between the body of the piston and the well casing, thereby obviating all possibility of the entrance of the sand into the valve cage 12 and its collection upon the valve seat 10. lrVearing of the seat is thus prevented and the perfect seating of the valve ball 11 thereon assured. The operation of the device will be readily understood by those familiar with the art. When the piston is moved downwardly into the well tubing, and its lower end enters the oil, said oil passes upwardly through the interior of the piston body 5 after entrance thereto through the perforations 22, and unseats the valve 11. This oil passes outwardly through the openings in the valve cage 12 and in the reverse or upward movement of the piston, the body of oil above the piston is drawn upwardly in-the well tubing and discharged therefrom in any usual or approved manner. My improved packing rings 16 absolutely prevent any return or downward movement of the oil between the wall of the well tubing and the valve.
From the above it will be seen that I have produced a very simple, reliable and durable oil well piston-which materially prolongs the life of the same and greatly minimizes expense incident to frequent repairs necessary to such pistons now in common use. The packing rings may be very easily and quickly arranged upon the body of the piston or removed therefrom when it is necessary to replace the same with new rings.
Owing tov the extremely simple construction of the invention it will be appreciated that the same can be produced at very small cost. While I have shown and described the preferred construction and arran ement of the several elements employed, it is obvious that the invention is susceptible of considerable modification therein and I therefore reserve the right to resort to all such legitimate changes as may be fairly em bodied within the spirit and scope of the invention, as claimed.
Having thus described the invention, what is claimed is:
The herein described valved piston including a tubular body reduced at one end and exteriorly threaded, said body having a valve seat formed on its other end, alternately arranged relatively long and short sleeves fitted upon said tubular body and having their corresponding ends reduced in diameter, a split resilient packing ring engaged upon the reduced end of each sleeve, the peripheral faces of said packing rings being normally disposed beyond the faces of said sleeves, the lower edge of each packing ring being beveled and designed for engagement with the upper edge of a well tube when the piston is inserted therein whereby the packing rings are contracted upon the reduced ends of the sleeves, and a valve cage removably engaged upon the upper end of the tubular body and having a ball arranged therein normally resting upon said valve seat.
In testimony whereof I hereunto afiix my signature in the presence of two witnesses. CHARLES M. MYERS. Witnesses:
