Archery sight and range finder
Abstract
Abstract A SIGHT AND RANGE FINER FOR ARCHERS, CONSISTING OF AN ATTACHMENT HAVING A VERTICAL SLIDE ON WHICH TWO SLIDERS ARE VERTICALLY MOVABLE. THE SLIDERS HAVE PARALLEL, HORIZONTAL SIGHT BARS, AND WHEN MOVED IN SPACED RELATION, ENABLE THE ARCHER TO SIGHT THE GAME BETWEEN THEM. ONE SIGHT BAR ALSO HAS A BULL''S-EYE SIGHT, TO ZERO-IN ON THE BODY OF THE GAME. A PIVOTED FINGER PIECE ON THE SLIDE CAN BE MANUALLY ADJUSTED, AND IS CONNECTED TO THE SLIDERS IN SUCH A MANNER AS TO NOT ONLY VERTICALLY ADJUST THE LATTER BUT ALSO TO AUTOMATICALLY VARY THE SPACING BETWEEN THEM, THIS BEING ACCOMPLISHED BY LINKS BETWEEN THE FINGER PIECE AND SLIDERS. GAME WHICH IS FAR AWAY AND APPEARS SMALL, REQUIRES CLOSE SPACING OF THE SLIGHT BARS WHICH RESULTS IN THEIR BEING AUTOMATICALLY POSITIONED VERTICALLY TO A LOWER LEVEL, TOGETHER WITH THE BULL''S-EYE SIGHT, SO AS TO PROVIDE FOR A HIGHER TRAJECTORY OF THE ARROW, AND VICE VERSA.
