摘要： A shoulder elevator having a gated pipe opening is disclosed. The elevator has a ringed body having unclosed sector creating an opening for receiving a pipe within the body ring. Pivotally mounted gates positioned on opposite sides of the unclosed sector of the ringed body, move in unison to an open and partially close the unclosed sector of the ringed body around the pipe in response to pipe contact with rearward end of the gates. A lever is provided to manually pivot the gates to an open and closed position around a pipe. Lifting lugs or ears are provided to attach the elevator to the lifting links of a hoist.

摘要： An apparatus and method for an integrated flush-mount spider and power-tong apparatus comprising a flush-mount spider integrated with an attached power-tong and electronic load cell torque monitor. The power-tong applies rotation in opposite directions to make-up and breakout the pipe string. The flush mount spider holds the lower pipe string in place and serves as a backup tong to prevent rotation of the lower pipe string. The addition of a pipe spinner allows the integrated flush-mount spider and power-tong apparatus to replace a top drive for advancing a wellbore.

摘要： A self-balancing, shoulder type elevator is comprised of two opposing jaws pivotally connected to a hinge plate. The jaws are engaged for rotation at the hinge plate by corresponding sets of gear teeth. Hangers on said jaws attach the elevator to suspending bails. An offset alignment linkage pivotally attaches each jaw to the hinge plate and a rotatable spindles pivotally attached perpendicular to said jaws. The alignment linkage maintains said spindles angularly congruent in orientation with the bails when the opposing jaws are pivoted open and closed.

摘要： The spider, arranged for support on a drilling rig, is fitted with a plurality of slips peripherally distributed about a slip bowl. Each slip has a plurality of pipe gripping dies distributed vertically and resting on individual abutment surfaces on the slip. Each slip has a generally vertical slide way to receive mating surfaces on the die for radial constraint of the dies.

摘要： A connector for connecting large tubes of the type used in oil well tubing, casing and the like, without resorting to welding, to form a pipe string for use in drilling. The connector comprises a pin and box threaded connection having guiding surfaces integral with the pin and box members to facilitate the threaded connection of large tubes. The connection is designed so that large tubes, for example tubes comprising an external diameter of two or more feet, may be joined by threaded connection facilitated by the integral guiding surfaces of the pin and box threaded members. The integral guiding surfaces allow large tubes, which are otherwise too cumbersome to position and manipulate for threaded connection to be practical, to be quickly and safely connected by threaded engagement of the pin and box members without the use of a weld between the tubes.

摘要翻译： 用于连接用于油井管，套管等中的大型管的连接器，而不用焊接，形成用于钻井的管柱。 连接器包括销和盒螺纹连接，其具有与销和箱构件成一体的引导表面，以便于大管的螺纹连接。 连接被设计成使得可以通过由销和盒螺纹构件的整体引导表面促进的螺纹连接来连接大的管，例如包括两个或更多个脚的外径的管。 整体引导表面允许大的管子，否则这些管子对于螺纹连接的位置和操作来说是非常麻烦的，以便通过销和箱构件的螺纹接合来快速和安全地连接，而不需要使用管之间的焊缝。
