  • Variable range sighting mechanism for use with archery bow
    Patent number: 4418479
    Abstract: A sighting mechanism for attachment to an archery bow or the like is adapted to provide accurate sighting in a number of ranges by an adjustment mechanism which changes the angle of elevation of a sight bar according to the desired range. A rear sight such as a V or peep may be moved back and forth in the sight bar to correct for wind conditions. Alternatively, the entire sight bar may be pivotally mounted at or near its center point so that it will swivel to allow for wind conditions.
