ABSTRACT:
An apparatus (10) for removable attachment to the adjustment ring (26) of telescope sights (12) for firearms (14) or the like is disclosed including a pinch clamping band (28) having an integral, elongated linear projection (42) extending axially therefrom. The clamping band (28) includes a split, annular wall (30) having a transverse radial cut defining first and second, free ends (32, 34). The free ends (32, 34) of the annular wall (30) are drawn together by a bolt (40) extending between bosses (36, 38) extending outwardly from the annular wall (30) on opposite sides of the transverse cut. A lever (50) has a securement end (52) positionable between the free ends (32, 34) of the annular wall (30) and including an aperture (60) for slideably receiving the bolt (40). The lever (50) extends axially from the clamping band (28) parallel to the axis (A) of the adjustment ring (26) and the projection ( 42). C-shaped adapters (46) having an internal surface for slideable receipt on the adjustment ring (26) and having an external surface for slideably receiving the annular wall (30) can be provided to allow the annular wall (30) to fit different sizes of adjustment rings (26). The adjustment ring (26) can be rotated by pushing the free ends of the lever (50) and/or the projection (42) at a location axially spaced from the adjustment ring (26) and adjacent to the ocular end of the eyepiece (22) to allow the hands of the shooter to be in an aiming and firing condition on the firearm (14) while adjusting the magnification of the telescope sight (12).
