SUCKER-ROD JOINT.
SEEOIFIGATION forming part of Letters Patent No. 735,030, dated July 28, 1903.
Application filed February 24, 1903. Serial No. 144,765. (No model.)
To all whom, it may concern:
Be it known that I, EMERSON B. CAMPBELL, a citizen of the United States, residing at Bakersfield, in the county of Kern and State of California, have invented certain new and useful Improvements in Sucker-Rod Joints, of which the following is a specification.
My invention relates to improvements in sucker-rod joints for deep wells, the object of my invention being to provide ajoint which shall be more economical in use than those heretofore used.
My invention therefore resides in the novel construction, combination, and arrangement of parts for theabove ends hereinafter fully specified, and particularly pointed out in the claim.
In the accompanying drawings, Figure 1 is a perspective View showing a sucker-rod joint of my improved construction. Fig. 2 is a longitudinal section of the same in the position the parts occupy while the rod-sections are being united. Fig. 3 is a similar view showing the device in the casing, parts being broken away.
The joint heretofore chiefly in use in pumping deep wells, such as oil-wells,is that known as the Acme joint, in which the lower end of the upper rod is formed with a socket threaded on its inner surface, into which is screwed the threaded lug or boss, extending upward from the upper end of the lower rod. It has also been necessary to provide on the upper end of the lower rod around said boss a shoulder against which the lower edge of the cup abuts to form a friction-joint. This was nec essary to prevent the rods unscrewing from each other since the upper rod was held stationary while the lower rod connected to the plunger, could rotate. The objection to this form of joint was that if the joint became broken, worn out, or useless in any way the whole rod was rendered useless, since the cup and shoulder were of much greater diameter than the rod.
It is the object of my invention to provide a joint which will permit of the rods being used over again when the joint wears out or becomes useless and at the same time will prevent unscrewing of the rods equally as well as with the old form of joint.
Referringto the drawings, 1 represents the rod-sections, and 2 is a coupling therefor, which is tapped entirely through. Into the ends of the coupling 2 are screwed the ends of the rod 1, thus uniting the rods together. In the side of the coupling is an aperture 3, leading from the interior to the exterior. The contour of surface of the coupling around the outer end of said aperture is free from protubera'nces. The success of the device is due to this aperture. Without it it has been found that a quantity ofoil and sand is inclosed within the coupling between the two ends of the rods. Acushion is thus formed between the two ends of the rods. Nowithas beenfonnd by practice that the above threads cannot be relied upon to afiord sufficient friction to prevent the rods from unscrewing. It is absolutely necessary to have abutments which by frictional contact with each other prevent unscrewing of the rod. By providing the aperture 3 the oiland sand are allowed to escape, and the rods may be allowed to be screwed up tight one against the other. They then receive the jar of the oscillation one from the other, and itis not received by the coupling, and thus the friction is su fficientto prevent unscrewing. The utility of this construction will appear from the considerations. It is frequently necessary to repair the pumps of oil-wells, and when this is done the rods have to be pulled out and disconnected and laid down, and as soon as the part of the pump attached to the lower end of these rods has been re-' paired they are immediately replaced. California oil being of a high specific gravity does not leave the rods freely and readily; but when the rods are being taken out and disconnected the oil is slowly dripping down and is still doing so when they are being replaced. This oil falls directly into the open end of the coupling, as the coupling is always directly under a rod when it is being connected or disconnected. This oil being of an asphaltic base is sticky and cannot be freely removed except by gasolene, so that it would require too much time to attempt to clean out this socket or coupling. The utility of the aperture is now apparent. As soon as the rod is screwed down into the coupling the oil is forced out through the aperture, which allows the rods to be screwed tight together.
This they could not do if this cushion of oil remained in the coupling. The aperture is therefore of very great importance;
4: represents jam-nuts which are screwed down in the ends of the rods onto the ends of 5 the coupling and which prevent the unscrewing of said rods from said coupling.
I claim In combination with sucker-rod sections, a hollow coupling therefor having a small lat- IO eral perforation for draining the oil and sand from the interior of the coupling between the
