Description

Patented Oct. 16, 1928 UNITED. STATES PATENT OFFICE.
DANIEL E. NORRIS, OF ROBINSON, ILLINOIS, ASSIGNOR TO NORRIS BROTHERS, IN- CORPORATED, OF ROBINSON, ILLINOIS, A CORPORATION ILLINOIS.
WORKING-BARREL-CLEANING DEVICE.
Application filed March 1, 1927. Serial No, 171.848.
In operating oil wells it is not unusual to withdraw the pump plunger for renewing the pump cups and also not unusual to withdraw the standing valve from the working barrel in order that the working parts of the valve may be renewed. To this end working barrels are usually provided with screws at the upper ends or" their cages which may be engaged by a screw lowered into the well and screwed'into engagement. IVorking barrels often become coated with deposits from the material pumped and this is more pronounced adjacent to the standing valve. The object of the present invention is to assist in clearing the working barrel of such deposit and provide a means by which thestanding valve may be engaged with certainty and withdrawn from the working barrel. and details of the invention will appear from the specification and claim. Y
A preferred embodiment of the invention is illustrated in the accompanying drawing which shows a central section of a working barrel with the standing valve puller in place therein.
1 marks the working barrel,2 the standing valveseat,3the standing valve, at the standing valve seating surface, 5 the cups of the standing valve, 6 the standing valve cage, 7 the stand ing valve seat, 8 the ball operating on the seat, and 9 a screw-threaded opening in the upper end of the cage. These parts are of common construction. A sucker rod 10 has the usual screw-threaded socket 11 at its lower end. A puller shank 12 is provided with a screw-threaded upper end 13 adapted to be screwed into the socket 11. It is vided with a square Wrench hold 14 to facilitate screwing it into place.
Features The lower end of the shank is screw-threaded at 15 and the screw thread is adapted to engage the screw threads of the opening 9.
The screw threads are slotted at 16 giving it the effect of a tap so that itmay cutits way into the opening 9 even though the ordinary threads therein are quite mutilated.
The shank is formed with a scraping blade 17 preferably in the form of a spiral which is adapted to it the walls of the Working barrel. I a
In operation the device is lowered into the working barrel and by reciprocating it at this point the working barrel walls may be completely cleaned. Any deposit, or material, there may be in the working barrel can be penetrated by'the device so that the lower screw is brought into engagement with the screw-threaded socket of the cap. The scraping blades not only scrape the walls of the working barrel but center the screw so thatit can readily enter the cap. Upon lifting the standing valve'the fact thatthe Walls of the working barrel are cleared assures the ready withdrawal of the valve through the working barrel, the scrapingblades carrying with them some ofthe material ahead of the valve.
WVhat I claim as new 1s A barrel cleaning device comprlsing scrapers adapted to scrape the walls of the Working barrel, said device having a screw-threaded lower end adapted to engage a standing valve, the scrapers extending to the upper end of the screw threads, and an upper end adapted to engage an operating rod.
In testimony whereof I havehereun'to set my hand.
DANIEL E. NORRIS.
