  • Apparatus for supporting an inspection device for tubular members and accommodating lateral shifting of the tubular members as they are run into or pulled from a well bore
    Patent number: 3936733
    Abstract: An arrangement for supporting a tubular inspection unit adjacent a well bore to enable tubular members to be moved through the inspection unit as they are run in or pulled from the well bore to determine characteristics of the tubular members. The arrangement includes an upwardly extending support for positioning adjacent the well bore and a laterally extending arm pivotally secured to the support and being normally positioned, during operation, at a given angular disposition with respect thereto. The pivotal connection allows, at all times, free angular movement of the arm with respect to the support and about a single axis in either angular direction away from the normal position. The arm comprises two members in telescoping relationship and arranged to accommodate, at all times, free axial sliding of one member with respect to the other in directions of both extension and retraction.
