ABSTRACT:
An adjustable bow sighting device in which a hollow carrier body has a slot formed on the exterior with tracks and on the interior with slots, so a rotatable threaded shaft directed parallel to the interior slots can be engaged by the eye of an actuator which extend through a slide block mounted on the body tracks. The eye of the actuator is formed with threaded elements and on adjacent smooth surface to embrace the threaded shaft so that where the thread elements engage the shaft rotation of the shaft can move the slide block according to the displacement of the thread pitch. A resilient element on the actuator holds the eye engaged on the threaded shaft but can be operated to disengage the eye from the threaded shaft for gross slide block adjustments independent of the threaded shaft. Multipoint contact can be made between the various body tracks, the threaded shaft, the slide block, once the sighting device has been accurately focused, and tightened into position, to assure that fixation of the set sight is maintained even during repeat usage of the bow.
