Abstract: Derrick mounted apparatus for the manipulation of lengths of pipe in or out of one or more finger boards in proximity thereto comprising a pipe manipulating arm adapted to move along a single predetermined line and a pipe gripping hand rotatably attached to one end of the pipe manipulating arm, the pipe gripping hand being capable of accepting and discharging pipe in an angular direction with respect to the line of movement of the arm.

Abstract: A pipe handling device for transporting pipe, drill collars, or like tubular members between the elevated drilling floor of a well derrick and a lower storage area has a pair of support cables extending between the rig floor and the storage area. A pipe trolley means rides the support cables and is movable along the support cables by a third cable to transport pipe from the storage area to the rig or to lay pipe down from the rig to storage. A cable draw works, typically in the vicinity of the storage area, anchors one end of the support cables and is provided with a take-up mechanism for the support cables to enable them to be slackened to enable a pipe to be loaded into or unloaded from the pipe trolley means in the storage area and thence tensioned to facilitate the travel of the trolley to the elevated rig floor.

Abstract: A tubing spreader mechanism for positioning vertically disposed tubing strings in a multiple completion well to maintain them in a desired center-to-center alignment. The tubing spreader has a support member designed to mount on top of a multi-string spider. An adjustable roller assembly is mounted to the support member and engages the tubing strings placing them in the desired center-to-center alignment with the spider. The tubing spreader mechanism can be used with tubing strings of identical diameters or different diameters.
