Abstract
Drilling apparatus for receiving, moving and aligning pipe sections as they are added to a string of pipe on a drilling rig when using an iron roughneck. After the iron roughneck is moved to well centerline and engaged with the box connection of the pipe suspended in the well bore, a hydraulically controlled pipe engagement mechanism is extended radially away from the iron roughneck and in the general direction of the pipe rack. The pipe engaging mechanism receives the lower end of the next stand of pipe to be added and is hydraulically retracted to lock around the pipe stand and bring the pipe stand into alignment with the pipe string suspended in the well bore.
