ABSTRACT:
A drive coupling for selectively disengaging a driving shaft and a driven shaft upon rotation of the driving shaft in one direction. The coupling comprises a pair of one-way clutches and a one space ratchet means so arranged to couple the shafts when the driving shaft is rotating in the normal direction and to uncouple the shafts upon the opposite rotation of the driving shaft. The coupling device is capable of remote operation as by reversing the current flow to the motor.
Such a device provides a convenient means for coupling and uncoupling pump stages in a submersible pump thus permitting adjustment of the performance of the pump by the addition or subtraction of pump stages without pulling the entire assembly from the well.
