  • Patent number: 4974328
    Abstract: A pendulum bow sight adapted for use on bows used from elevated positions such as tree stands and the like includes a mounting frame for attaching a pendulum and a pendulum frame to a bow. The pendulum and pendulum frame are pivotally mounted to the mounting frame to move independently of each other. The lower surface of the pendulum frame, which is formed in an arc, has square teeth which engage similar teeth on an upwardly disposed surface at the lower end of the pendulum. The pendulum frame has integral elongate slots to accept a slidably mounted sighting pin. A fixed sighting pin is mounted through the pendulum/pendulum frame pivot axis. Range and tree stand height markings can be placed on the pendulum frame. The sight can be mounted for use by either a right-handed or left-handed archer.

  • Patent number: 4785541
    Abstract: A bow mountable range finder for elevated tree stand use includes a housing and a triangular tubular chamber containing air and medium viscosity liquid. The triangular chamber contains a horizontal venting section, a vertical indicating section, an inclined section and a horizontal reservoir with air and liquid freely movable throughout chamber depending upon the orientation of the range finder. The indicating section is translucent and has a removable graduated scale calibrated for various heights above ground, a battery powered lamp illuminates through the indicating section and scale. A switch is operable by an archer outwardly of the housing.The reservoir section is sized to accommodate approximately one-half the fluid capacity of the indicating section when the range finder is horizontal and thus allows for rapid lowering of the liquid level when the range finder is rotated counterclockwise.
