The invention comprises a reverse telescopic kelly bar that includes an outer bar, any number of middle bars, and an upper inner bar. Each section has its own driver that either rests on top of the adjacent, lower larger diameter section or is engaged to the rotary. The entire assembly is suspended by a swivel attached to a multi-shieve traveling block.
When a section is rotated, it is either rotated by its driver via the rotary or by the connected and adjacent lower and smaller diameter section. Upper inner lugs are provided on the inside of the hollow sections. These upper inner lugs are located near the upper part of the middle bar and lower outer sections so that they can receive torque, if required by the cross-section, when fully extended from one section to another section below the rotary. A thick ring is welded to the bottom of the middle section and upper inner section. The inside lugs and the bottom ring also act as a stop to hold the adjacent sections together when they are fully extended so that adjacent sections can be supported from the other.
