The new gear device enables changing the angle of the propeller blades to the airflow. The blades of a propeller (or elevator, it sometimes says) can close, open, or reverse so that the engine might continue running but the propeller's effect is changed. "Closed" means the propeller blades are all practically in one plane, that is, not cutting the air. Patent says it's relevant to airships and aeroplanes with propellers or elevators.
