ABSTRACT:
A portable, pocket sized instrument for measuring wind speed and indicating wind direction wherein a multiple number of vanes of varying size and spacing are radially and orthogonally fixed to a disc and wherein the force of the wind against the vanes causes the disc to rotate against the restraining torque of a spring. Wind speed is indicated by angular rotation of the disc and wind direction is indicated by the orientation of the instrument at the time of maximum reading. A foldable handle protects the mechanism and increases the convenience of positioning the instrument.
