JACK E. GIBSON PIPELINE BUILDING METHOD AND APPARATUS ABSTRACT OF THE INVENTION Apparatus for forcing threadless lengths of pipe axi- ally into a coupling to effect a string of pipe. The apparatus includes a main frame movable longitudinally along the projected path of a pipeline to be constructed. A pipe gripper is mounted to the main frame for slidable movement longitudinally along the pipeline. The pipe gripper comprises a plurality of pipe engag- ing dies remotely actuated to grip and release a marginal length of a pipe. A coupling holding fixture is affixed to the main frame in spaced relation respective to the pipe gripper. The fix- ture includes a movable wall which enables a coupling to be re- leasably held in fixed relationship respective to the main frame, and remotely released when desired. A coupling is placed within the fixture, a length of pipe is engaged by the pipe gripper which forces the pipe axially into the coupling whereupon the pipe con- nection is effected to thereby enable a pipeline to be fabricated. -1-
