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 apparatus for transporting pipe, drill collars, or similar elongate members between the elevated drilling floor of a well derrick and a lower storage area is disclosed. The apparatus comprises a pair of support cables forming a cable track extending between the rig floor and the storage area with a rear bucket that receives and holds the lower end of the pipe riding on the support cables. The rear bucket is movable along the cable track by a third cable which controls the transporting of the pipe from the rig to the storage area in a pipe lay-down operation. A series of support buckets is anchored proximate the rig floor and is extendable along the cable track as the pipe is being transported, providing support to the intermediate portion of the pipe.

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.
