Description

Patented Dec. 16, 1930 NITED STATES PATENT OFFICE JOHN D. LEMEX, OF TULSA, OKLAHOMA, ASSIGNOR, BY MES NE ASSIGNMENTS, TO OIL -WELL SUPPLY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OF NEW JERSEY BACK-PRESSURE JOINT Application filed June 5, 1928. Serial No. 283,011.
My invention relates to a tool joint and back pressure valve structure, and more particularly to a drill pipe float joint or coupling designed for connecting adjacent sections of a drill pipe, and primarily employed in lowering or floating a drill pipe into a well in order to reduce the weight of the pipe being handled, for the purpose of reducing the strain and wear on the equipment em- 1 ployed for lowering the drill pipe into position in a well.
The prime object of the present invention is to provide a strong, durable and eflicient joint or coupling of the character specified and of such construction that, in case the valve mechanism is rendered inoperative, an uninterrupted passage of fluid through the coupling may be effected.
Other objects of the present invention are, to provide a back-pressure or float valve coupling having an integral valve seat formed on a reduced portion of the coupling, and having an adjustable valve guide mounted in an enlarged portion of the coupling below said valve, said guide being of such character that the area of the opening or openings therein. for the passage of fluids therethrough. is greater than the area of the valve and a spring-controlled valve of improved construction for controlling the passage of fluids through the coupling.
In the accompanying drawings, which illustrate an application of my invention:
Fig. 1 is a vertical sectional View of a joint or coupling member and back pressure valve embodying my invention; and
Fig. 2, a top plan view of the valve guide member.
Referring to the drawings, the joint or coupling comprises a hollow body 5 constituting. as illustrated. a hollow pin member 6 and a box-member 7. Box-member 7 at its upper end is formed with a tapered interiorly threaded pin-receiving portion 8, into which a lower threaded tapered portion 9 of the pin member is entered. The opposite end of said members are adapted to receive the adjacent ends of two drill pipe sections A and B. and are each threaded, as shown at 10 and 11 respectively.
is preferably of the form shown, and in-.
cludes an elongated stem 16 formed integral with the valve roper. This stem is slightly reduced, as at 1%, and this reduced portion is adapted to be projected through a stem-receiving portion 18 of the valve guide means or member 12. Valve has a conical contacting seating surface (1 adapted to make a close fit with the inclined face of valve seat 1 19 designates a coil spring having an end thereof seated upon portion 18 of the guide means and its other end disposed in an annular recess 20 of the valve. Spring 19 exerts suflicient pressure on the valve to maintain the valve on its seat during the operation of lowering the drill pipe into the well, and the valve will remain in its closed position until the circulating fluid is admitted to the drill pipe and the pressure of said fluid overcomes the pressure of the spring and any other pressure below the valve.
The guide member 12 is designed to be adjustably supported within the large portion of the coupling, and for this purpose it has an annular threaded portion 21 having its threads engaging the threaded portion 11 of box member 7. The preferred form of member 12 is particularly shown by Fig. 2 of the drawings, and as there shown, it is formed with radially extending members 22 extending from the stem-receiving portion '18 to its annular portion 21, and with large openings 23 for the passage of fluids through the guide member. The combined area of these fluid passages 23 is greater than the area of the valve 15, thus ensuring an uninterrupted passage of the circulating fluid through the coupling at all times, even should the valve or its stem break and fall onto the gulde.
I claim:
1. A drill pipe float joint comprising a hollow body havin an interiorly extending portion integral tfierewith formed with a reduced bore portion, said portion on one side being ad: ted for abutment by the adjacent element of the drill pipe line and on its other side providing a valve seat, a valve guide within and supported by the hollow body below the seat, and a spring pressed valve interposed between the guide and the seat, said guide having a fluid passage area greater than the valve area to permit of an uninterrupted flow of fluid through the joint.
2. A drill pipe float joint comprising a hollow body having an interiorly extending portion integral therewith formed with a reduced bore portion, said portion on one side being adapted for abutment by the adjacent element of the drill pipe line and on its other side providing a valve seat and with an enlarged valve guide receiving portion, a valve guide mounted within the enlarged portion and provided with screw-threads, and a spring controlled valve interposed between the valve seat and guide, said enlarged portion having similar interior screw-threads over an extended surface for engagement by those of the guide to accommodate'the mounting and adjustment of the guide and attachment of the body to drill pipe.
3. A drill pipe float joint comprising a box member and a pin member, said box member having a portion integral therewith and on the interior thereof having a reduced bore therethrough and a valve seat on one side and an abutment 0n the other side engaged by the pin member, an enlarged valve guide receiving portion, a valve guide adj ustably mounted within the enlarged portion, and a spring controlled valve interposed between the valve seat and guide.
In testimony whereof I aflix my signature.
