  "abstract": "This disclosure relates generally to couplings used in mining and other applications. An extraction device for removing an adapter from a port formed in a structure is provided. The extraction device may include an end wall and a side wall. The end wall may define an external face of the extraction device. The side wall may extend axially away from a periphery of the end wall. The side wall may terminate at an end face of the extraction device. The end face may have a larger dimension than the port so as to abut the structure adjacent to a periphery of the port. The side wall may include an inner surface and an outer surface. The inner surface may have a threaded portion.",
  "claims": [
    "1. A method of removing an adapter from a port defined by a structure, the method comprising: positioning a one-piece extraction device around a portion of the adapter; threadedly engaging an internal thread of the extraction device with an external thread of the adapter by rotating the extraction device about the adapter; abutting a leading edge of the extraction device against an external face of the structure; axially extracting the adapter at least partially from the port by continuing to rotate the extraction device about the adapter after the leading edge of the extraction device is abutted against the external face of the structure; and engaging an external annular shoulder positioned proximate to the leading edge of the extraction device with a pry tool and thereby applying an axial force to move the extraction device axially away from the structure.",
    "2. The method of claim 1 further comprising advancing the extraction device axially along the adapter toward the structure prior to abutting the leading edge against the structure by continuing to rotate the extraction device about the adapter."

  "description_excerpt": "Field This disclosure relates generally to couplings for mining and other applications, and more particularly to a device that removes an adapter from a port. Related Art Adapters are commonly used in mining and other applications to couple together various types of hoses, tubing, pipe, manifolds, and other suitable structures. The adapters may be difficult to disconnect or remove from the structure to which they are attached due to various factors including debris, corrosion, and mechanical interference between the components. To remove an adapter from an associated structure, field personnel often resort to physical force applied by chisels, hammers, or other readily available tools, which frequently damage the adapters and may be a time consuming process. Further, the resulting damage to the adapters, such as cracks, may be undetected and result in catastrophic failure of the coupling assembly if the adapter is used in future applications.\n\nThe present disclosure is generally directed to systems and methods for removing an adapter secured in a port. Examples of the disclosure may include an extraction device for removing an adapter from a port formed in a structure. The extraction device may include an end wall and a side wall. The end wall may define an external face of the extraction device. The side wall may extend axially away from a periphery of the end wall and terminate at an end face of the extraction device. The end face of the side wall may have a larger dimension than the port so as to abut the structure adjacent to a periphery of the port. The side wall may include an inner surface and an outer surface.",
