Abstract
A wind speed and wind direction indicator is constructed on a center support pole or mast having a vertical scale of wind speed indicia for visually reading wind speed at a distance from the pole. A swivel head is mounted at the top of the pole for rotation to different compass directions. A rigid arm pendulum is pivotally coupled to the swivel head for pivotal motion of the pendulum to different angles with respect to the support pole. A wind drag structure such as a wind sock is coupled to the free end of the rigid arm pendulum for angular positioning in response to varying wind speed. A sliding collar is mounted on the support pole for sliding motion up and down over the scale of wind speed indicia. A line is coupled between the free end of the rigid arm and the sliding collar for sliding motion of the collar over the scale of wind speed indicia in response to varying wind speed. A generally cylindrical compass direction sleeve is mounted on the support pole in relation to the swivel head and rigid arm pendulum. It is formed with wind direction compass indicia around the support pole for visual reading at a distance from the pole. The compass sleeve may be secured to the swivel head for rotation with the swivel head for indicating compass direction of origin of wind from a selected vantage point.
