ABSTRACT:
A method and device for positioning and guiding pipe, including coupling and uncoupling pipe, in a drilling derrick having a work table for securing pipe extending into the well. The upper end of a first pipe section is received and horizontally secured by a mechanical arm attached to the derrick pipe so that the upper end of the first section is disposed above a second pipe section secured in the work table. In uncoupling the first pipe section is unthreaded and raised prior to releasing it from the mechanical arm. In coupling, the first pipe section is lowered and coupled to the second pipe section prior to releasing it from the mechanical arm. The mechanical arm is movable from a horizontal to a vertical position to avoid obstructing the work area. A lock and a remote fluid operating system are preferrably provided for the arm.
