on-saivme DEVICE ran on. wants.
Application filed February 13, 1922. Serial No. 536,117.
To all whom it may concern:
Be it known that I, Onor B. ANDERSON, a citizen of the United States, residing at Marquette, in the county of Marquette and State of Michigan, have invented certain new and useful Improvement-in Oil-Saving Devices for Oil Wells, of which the followin is a specification.
y invention relates to oil saving devices for oilwells. An object is to provide a device which will automatically close the upper end of the well casing or pipe sections when oil is struck so as to prevent the wastage of the oil by escape from the casing.
Anobject in particular is to provide an at-' tachment for the upper end of the well casing whereby the pressure of the upwardly flowing oil will cause a tight joint to be made between the drill rod and the surrounding casing.
The full objects and advantages of my invention will appear in connection with the detailed description, and the novel features embodied in my inventive idea will be particularly pointed out in the claim.
In the accompanying drawings which illustrate one embodiment of my invention, Fig. 1 is an elevational View of the devioe with a portion thereof shown in vertical. section. Fig. 2 is a view in horizontal section on the line 22 of Fig. 1.
Referring to the construction shownin the drawings, the numeral 10 designates the upper section of a plurality of i sections which are put into the ground diiring the operation of drilling oil wells, and the numeral 12 designates any customary drill rod vwhich operates within the pipe sections or well casin The upper end of the pipe section 10 is threaded for engagement of a union member 14 which has a lateral opening to which a branch pipe 16 is attached by a threaded member 18 containing a valve which is operated by a rod20. A short pipe section 22 is threaded into the upper end of the member 14 and a short pipe section 24 is threaded into the upper end of the section 22. The section 24 above its lower threaded end is provided with an annular shoulder 26 connecting with an enlarged portion 28 of this section and the up er end of the enlarged portion is extermfily threaded to receive a cap 30 through which the drill rod 12 extends. A ring 32 is placed on the annular shoulder 26 and the lower face of this ring is provided with an annular groove 34 into which leads a perforation 36 extending through the shoulder 26. The upper side of the ring 32 is reduced to form an annular member 38 which is provided with a lateral perforation 40. A perforation 42 leads from the groove 34, through the body of the ring 32 to the outside of the reduced portion 38. A gasket 44 of suitable fiexibl material extends from the outside of the member 38 over the top of the of the body member of the ring 46. A ring 52 is placed upon the bent over upper portion of the gasket 50 and this ring is adapted to be engaged by the cap 30 when the latter is screwed down.
The operation and advantages of my invention will be readily understood in connection with the foregoing description.- The space between the pipe section 24 and the drillrod 12 is connected with annular groove 34 by the perforation 36 so that when oil starts to flow upwardly the pressure thereof 1s exerted through the perforation 36 and. the perforations 42 and 40 so as to be communicated to the outside of the inner member of the gasket 44, thereby forcing the same all the way around its circumference into intimate contact with the drill rod and preventing the escape of oil out of the top of the well casing. It will be understood that the device containing the gaskets is attached to the upper sectionof the pipe conative positions. It will be-apparent that upon screwing down the cap- 30, both of the gaskets and 50 will be expanded into contact with the drill rod so that a tight stituting the Well casing, before there is like joint may be made manually as well as automatically. When my device is used, the escape of oil from the well casing will be prevented, and the oil will be delivered from the well through the branch pipe 16 only when permitted by opening the valve which is attached to the valve rod 20. It will be noted that the pressure of oil through the perforation 42 also causes the outer member of the gasket 44 to be forced into intimate contact with the inner wall of the jacket or enlarged member 28. In order that this action may be efiected, the lower inner edge of the outer gasket member is preferably beveled as shown. The ring 46 rests upon the bent over portion of the gasket 44 and in connection with the cap 30 and ring 52 serves to restrain upward movement of the gasket 44 so that the latter is caused to tightly engage the drill rod by pressure of oil within the well casing.
having an internal shoulder provided with' a perforation, a ring resting upon said shoulder and having a circumferential groove with which said perforation communicates, a reduced member connected with the upper end of said ring, a gasket extending over said reduced member and upon both sides thereof, said reduced member containing a lateral perforation and the body of said ring containing a perforation leading from said circumferential groove to the outside of said reduced member, and means for restraining upward movement of said gasket.
In testimony whereof I hereunto afiix my signature.
OLOF B. ANDERSON.
