Abstract
The drive shaft assembly comprises first and second telescoping shafts supported above ground level. A motor is coupled to the first shaft for extending it in an axial direction. Another motor is connected to the second shaft for rotating the second shaft about its longitudinal axis. These shafts are connected by a coupling so that the second shaft rotates the first shaft in all positions of the first shaft. The first shaft terminates at a free end in a frictional engageable end portion.
