  • Patent number: 4555856
    Abstract: A bow sight for use with compound bows, recurve bows and long bows which includes a housing enclosing a bottom mirror, a top mirror mounted in spaced relationship in the housing with respect to the bottom mirror and a narrow compensating mirror positioned in the housing in close proximity to the bottom mirror. The top and bottom mirrors are mounted in substantially parallel relationship at approximately a 45.degree. angle in the housing and the top mirror and compensating mirror are pivotally mounted, with the compensating mirror adjustably responsive to manipulation of a lever from a calibrated position. The target image segment projected from the top mirror to the bottom mirror is compared to the target image segment projected from the compensating mirror to the bottom mirror and the lever is moved rearwardly, if necessary in order to provide the necessary adjustment to align the segments and determine a proper trajectory for accurately delivering an arrow to the target.

  • Patent number: 4507874
    Abstract: A bow sight for use with compound bows, recurve bows and long bows which includes a housing enclosing a bottom mirror, a top mirror mounted in spaced relationship in the housing with respect to the top mirror and a compensating mirror positioned in the housing in close proximity to the bottom mirror and smaller than the bottom mirror. The top and bottom mirrors are mounted in substantially parallel relationship at approximately a 45.degree. angle in the housing and the top mirror and compensating mirror are pivotally mounted in order to provide the necessary adjustment to determine a proper trajectory for accurately delivering an arrow to the target when the target is viewed through the bottom mirror and the target image in the bottom mirror is compared to the target image from the compensating mirror.
