Abstract: The present invention provides a “third-axis” leveling block for use with an archery sight. The third-axis leveling block holds an archery sighting device (e.g., a scope or a pin sight) as know in the art. The leveling block adjusts the position of the sight in two axes by means of cams. One of the cams adjusts the sighting device to the archer's preferred cant. The other cam adjusts the angle of the sighting device with respect to the bow to keep the archer's cant consistent when the bow is raised or lowered for shooting at targets at any elevation, above, below, or on the same level as the archer.

Abstract: A bow sight includes an elevation block which may be operably coupled to and uncoupled from an adjusting screw by a locking member which need not be held manually in either its locking position or its unlocking position. The elevation block is supported rigidly on the frame of the sight by a three-point suspension and carries a windage block which also is rigidly supported by a three-point suspension. The outer end of the windage block is formed with a half-dovetail connector which coacts with a complementary half-dovetail connector on a sighting device to enable the sighting device to be clamped rigidly to the windage block by a single screw.
