ABSTRACT:
A bracket plate type of scope sight mounting for archers, which may be constructed for mounting on a bow, either rearwardly of the bow toward the archer or forwardly of the bow away from the archer, has a rack and pinion mechanism for adjusting range of an arrow's flight, the rack of which mechanism is curved along its length and is affixed to an elongate bracket plate which is adapted to itself be affixed at one of its ends to a bow. The rack fits into an open, slideway groove formed in and extending transversely of the longitudinal extent of an elongate scope sight mounting block that is adapted to be slidably attached to the bracket plate, at one face thereof for up and down movement relative thereto, by structure including the pinion of the rack and pinion mechanism and desirably by a special washer assembly that provides resiliency. A scope sight mounting arrangement, which may be of dovetail type, extends slidably through the bracket plate and is adapted to carry a scope sight at the opposite face of the bracket plate for up and down movement with mounting block.
