ABSTRACT:
Windage locking apparatus for an archery bow sight. The apparatus includes aperture, barrel, and body members concentrically positioned within each other about an axis and common locking structure to selectively lock these member together to prevent relative movement among them about and along the axis. The common structure includes a single set screw extending outwardly of the axis through the barrel and body members and a locking knob to fit on the portion of the set screw protruding outwardly of the body member. In operation and with the set screw securely holding the aperture and barrel members together, the locking knob can be tightened on the protruding portion of the set screw to draw the barrel member into frictional contact with the surrounding body member to lock the aperture, barrel, and body members securely in place for shooting. Additionally, the present invention provides structure to keep the locking knob from being separated from the set screw and possibly becoming lost.
