COUPLING.
SPECIFICATION forming part of Letters Patent No. 232,722, dated September 28,. 1880.
Application filed July 22, 1880.
To all whom it may concern:
Be it known that I, WILLIAM J. INNIS, of Oil City, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Gouplin gs for Oil- IVell Tubing and Anchor; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and the letters of reference marked thereon, which form a part of this specification.
My invention relates to improvements in connections between the tubing and anchor in an oil-well.
Oil-wells are tubed with two-inch tubing. Above the oil-bearing rock a packer is placed around the tubing, which causes the and oil from the lower part of the well to ascend through the tubing. That part of the tubing which extends from the packer to the bottom of the well is called the anchor, and is generally perforated with small holes in order to allow the oil and gas to pass into the tubin As such perforations cannot be made large without weakening the anchor, they are made so small as not to afford as free passage for the oil as is desirable. The anchor should not only be strong enough to sustain the tubing, but, as it frequently happens that sand and sediment collect around its bottom, it is liable to part when a strain is applied to withdraw it ifit has been weakened by too many or too large perforations.
X T's have been used to form the connection between the tubing and anchor; but they are not strong, and the two channels which allow the oil to enter being directly opposite each other, the streams expend a portion of their force upon each other, and thereby diminish the power by which the oil is forced out of the well.
My improved coupling remedies the defects alluded to, as I secure sufficient strength of union between the tubing and anchor, and also free passage for the oil. I attain these objects (No model.)
by a coupling, the most desirable form of which is illustrated in the accompanying drawings.
Figure 1 is a perspective view of my improved coupling, and Fig. 2 is a vertical section.
A is a socket, which has the interior screwthread a, to receive the lower end of the tubing. B is a socket with the interior screwthread I), to receive the upper end of the anchor, and these two sockets A and B are united by the ribs D.
I think it better to add the funnel E, and place the socket A in the small end of such funnel, and attach the ribs D to the large end thereof. Such funnel will then collect the oil and by its sloping sides direct the currents into the tubing; but it may be omitted, as the main feature of my invention is to have the sockets united by ribs sufficient in number to give the needed strength, and so small as to afford no obstacle to the flow of oil.
By thus uniting the sockets A and B by long and narrow ribs D large areas are secured for the passage of gas and liquid.
What I claim as my invention is-- l. A homogeneous coupling made independent of any valve to unite the tubing of an oil-well to its anchor and allow free and unchecked passage for the oil, said coupling consisting of a conical funnel at its upper end, with a screw-thread to attach it to the tubing, and its screw-threaded lower end united to said conical funnel by ribs, substantially as shown and described.
2. A homogeneous coupling for oil well tubing and its anchor, consisting of an upper and lower socket interiorly screw-threaded, an upper portion formed of a conical funnel having unperforated walls, and a lower portion formed of ribs having radial openings between them, substantially as and for the purpose described.
WILLIAM J. INNIS.
