STAND-VALVE-EXTRACTING MEANS FOR OIL-WELL PUMPS.
Specification of Letters Patent.
Patented oet; ea, fare.
Application filed August 8, 1916. Serial No. 113,814.
To all whom it may concern:
Be it known that I, DANIEL E. NORRIS, a citizen of the United States, residing at Robinson, in the county of Crawford and State of Illinois, have invented new and useful Improvements in Stand Valve Extracting Means for Oil-Well Pumps, of
the standing valve may be pulled out with the plunger.
This has heretofore been accomplished by providing one of these parts with a threaded perforation and the other part with a screw adapted to engage the screwthreaded perforation by turning the pluner. The difiiculty with this method comes from the jamming or injuring of the threads of one of the parts. Where this occurs the parts cannot be united. so that the device becomes useless. The object of the present invention is to obviate this difficulty.
The invention is illustrated in the accompanying drawings as follows s Figure 1 shows a central'vertical section of a pump.
Fig. 2 a crosssection on the line 2-2 in l marks the working barrel, 2 the strainer, 3 the standing valve fitting, 4 the standing valve, 5 the packing on the standing valve forming a. joint with the bottom of the working barrel and fitting, 6 a cage on the standing valve, and 7 a screw-threaded perforation in the top of the cage.
A plunger 8 is provided with an extension 9 having openings within its walls leading to the interior of the plunger and the usual passage .through the plunger.
The extension has its interior walls formmg a hexagonally shaped pocket in which a head 11 is slidingly mounted. A spring 12 forces the .head to the lower end of the pocket. The lower end of the pocket is provided with a perforation l3 and a tap 1 1 is secured to the head 11 and extends through the erforation 13.
T e tap 14 is designed to enter the perforation 7 and cut a thread therein when the plunger is turned, thus securing the plunger and standing valve together. By
forming a yielding support for the tap the great weight to which the plunger is subjected will not interfere with the proper running forward of the tap in forming" the threads. Ordinarily I prefer to form the threads initially in the opening 7 and the work of the ta will then simply be to re-cut the threads w ere they are ammed or injured.
In operating the device, the plunger is lowered so that the lower end of the plunger rests on the top of the opening 7. The tapwill be forced back into the perforation 13 compressing the spring 12. As the lunger is rotated the tap will feed forward into the thread in the opening 7 or will form a. screw in such opening, thus assuring the attachment of the standing valve to the plunger.
What I claim as new is In a stand valve extracting means for oil well pumps, .the combination of a standing valve havinga valve cage thereon with a perforation in the top; a plunger with an extension thereon; a tap. having a head mounted in the extension and locked against turning therein; and a spring yieldingly holding the tap in its lower position, said tap being adapted to enter the perforation in the cage, thread the same and secure the cage and plunger together, the spring exerting pressure to start the tap.
In testimony whereof I have hereunto set my hand.
