ABSTRACT:
A fan operator lever vibration dampener for a variable pitch fan whose blade pitch is varied by movement of an elongated operating lever extending through a slot in a wall of the fan. The dampener comprises a pressure plate located between the projecting extremity of the operating lever and one of the slot side margins. The plate is movable toward and away from the lever extremity. Bias means interposed between the lever extremity and the pressure plate tend to urge the lever extremity and pressure plate against the slot margins to prevent vibration.
