Abstract
A general housing encloses a drilling motor that can be disabled to permit optimum rotary drilling practice. A mode selector responds to manipulation of the drilling fluid flow rate and permits activation of the drilling motor to drive a drill bit. The general housing is a two part arrangement that is connected by a deflection arrangement that is activated by start-up of the motor. A one-way clutch allows the lower housing to drive the drill bit when the motor is disabled and the clutch, with drill bit rotation resistance, changes the deflection arrangement for straight rotary drilling when the drill string is rotated.
