Abstract
A control mechanism to dampen gimbal tumbling and to orient the axes of rotation of the rotor and the gimbals of a gyroscope when in an inoperative state. The control mechanism serves as an overriding stop to gimbal lock, dampens the gimbal rotation leading to tumbling and restores the gimbals to a given orientation upon the cessation of gimbal rotation. The overriding stop and dampening force in one embodiment are the plurality of cams and cam followers rotatably mounted and operatively connecting the inner and outer gimbals with the gyroscope frame, and in another embodiment a cam and cam follower arrangement rotatably mounted and operatively connecting the inner and outer gimbal in combination with a bearing surface operatively connecting the inner and outer gimbal with the gyroscope frame.
