Patent Application
20230258045
This application relates in general to an article of manufacture for providing an oil extraction device, and more specifically, to an article of manufacture for providing a rod coupling remover device.
Oil extraction from wells require a rod string of sucker rods to be coupled together to connect a pumping unit to a pump within the wellhead. In order to maintain the well and ensure its operation, the rod string needs to be maintained with various sucker rods being replaced periodically. A user typically finds the process of removing and attaching each sucker rod from the rod string difficult as the sucker rods are coupled together by a set of rod coupling devices. These rod coupling devices are difficult to restrain while constructing the rod string as the rod coupling devices need to easily move within the wellhead.
Therefore, a need exists for an article of manufacture for providing a rod coupling remover device. The present invention attempts to address the limitations and deficiencies in prior solutions according to the principles and example embodiments disclosed herein.
In accordance with the present invention, the above and other problems are solved by providing an article of manufacture for a rod coupling remover device according to the principles and example embodiments disclosed herein.
In one embodiment, the present invention is an article of manufacture for providing a rod coupling remover device. The rod coupling remover tool includes a body having a top end, a bottom end, and a shaft opening running from the top end and the bottom end, a bifurcated threaded portion about the bottom end of the body, a retractable wedge, a shaft opening running from a top end to a bottom end of the body, and a threaded shaft member coupled to the retractable wedge at the bottom end of the body. The threaded shaft member passes through the shaft opening of the body in which the retractable wedge is movable into and out of the shaft opening of the body.
In another aspect of the present invention, the remover tool further includes a tightening nut coupled around the threaded shaft member about the top end of the body, the tightening nut rotates about the threaded shaft to prevent movement of the retractable wedge once the retractable wedge is within the shaft opening of the body, and an enlarging slit vertically positioned along the bifurcated threaded portion.
In another aspect of the present invention, the retractable wedge enlarges the bifurcated threaded portion of the body as the retractable wedge enters the shaft opening into the body.
In another aspect of the present invention, the bifurcated threaded portion of the body is configured to engage a rod coupling having a threaded cavity having one or more threaded diameters.
In another aspect of the present invention, the bifurcated threaded portion has a threaded diameter comprising ¾″, ⅞″, and 1″.

In general, the present disclosure relates to an article of manufacture providing a rod coupling remover device according to the present invention. To better understand the present invention,
The present invention compromises a tool 300 as shown in
The bifurcated threaded portion may include the retractable wedge 303 to increase the rod coupling remover tool's 300 ability to remove necessary rod couplings 201 from an existing rod string 103. The rod coupling remover tool 401-403 can be made for all sizes of rod couplings, 1″; ¾″; ⅞″ among others as shown in
To use the rod coupling remover tool 300, the bifurcated threaded portion 302 is coupled to a rod coupling device 201 in the same manner as a sucker rod 202a-b. The rod coupling remover tool 300 is easily coupled to a hand-tight configuration by a user.
The retractable wedge 303 may be retracted into the bifurcated threaded portion 302 by pulling the threaded shaft 304 at the opposite end of the body 301. The retractable wedge 303 widens toward its outer end that exerts a force upon the bifurcated threaded portion 302 causing the bifurcated threaded portion 302 to expand via the slot 306 through the bifurcated threaded portion 302. The tightening nut 305 may be rotated to further retract the retractable wedge 303 to tighten the bifurcated threaded portion 302 within the rod coupling device 201. When the tightening nut 305 has been tightened, the rod coupling remover tool 300 is securely coupled within the rod coupling device 201.
The rod coupling remover tool 300 may be secured by securing the body 301 of the rod coupling remover tool 300 to allow a user to untighten and remove a sucker rod 202b from the opposite end of the rod coupling device 201. Once the sucker rod 202b has been removed from the rod coupling device 201, the rod coupling remover tool 300 also may be removed by untightening the tightening nut 305 and reversing the above steps to disconnect the rod coupling remover tool 300 from the rod coupling device 201.
Even though particular combinations of features are recited in the present application, these combinations are not intended to limit the disclosure of the invention. In fact, many of these features may be combined in ways not specifically recited in this application. In other words, any of the features mentioned in this application may be included in this new invention in any combination or combinations to allow the functionality required for the desired operations.
No element, act, or instruction used in the present application should be construed as critical or essential to the invention unless explicitly described as such. Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise.
