ABSTRACT:
This invention provides an oil well drilling or service rig having inclined capability with pipe handling means which will automatically retrieve pipe from a horizontal pipe rack, tilt it into a position parallel to the mast, and transpose it into the center line of the mast in line with the drill string and stab the pipe into the drill string for make-up while the elevators are being moved into position to lower the string. The pipe handler can also be used to withdraw pipe from the string in the reverse operation.
