Wind direction indicator

Image Number 2 for United States Patent #5065622.

This wind-direction indicator includes a pointing beam having a tail at one end formed by diverging feather segments, with a transverse hole in the central portion of the beam receiving a standard straight pin. A glass bead is interposed between the head of the pin and the underside of the beam, the upper extremity of the pin being attached to a standard alligator clip for attachment to a convenient twig. The hole receiving the pin is sufficiently larger than the pin to permit considerable rocking movement about a horizontal axis, and the beam is balanced after the assembly of the feathers by clipping the upwind end of the beam. This end is later finished by a short dip in a fluorescent paint, the rest of the device being finished either balck or with a camouflage pattern.
