Abstract : The patent is directed to a friction means which damps rotational movement of a weather vane due to wind shifts. The friction means is mounted relative to the vertical support shaft about which the vane rotates to align with the wind direction. The friction means prevents quick rotational movements of the support shaft so that more accurate true wind direction is obtained.
