Abstract:
1. A turret knob for independently controlling two orthogonal optical adjustments of an optical scope, comprising: a first adjustment member adjustably positionable about an axis of rotation to adjust an optical adjustment of the optical scope in a first direction; a second adjustment member adjustably positionable about the axis of rotation to adjust the optical adjustment of the optical scope in a second direction, the second direction being orthogonal to the first direction; and a slip/engagement member positioned between the first adjustment member and the second adjustment member along the axis of rotation, the slip/engagement member being movable between a first position and a second position and a third position along the axis of rotation, in the first position the slip/engagement member does not engage the first adjustment member or the second adjustment member, in the second position the slip/engagement member engages the first adjustment member to rotatably adjust the first adjustment member about the axis of rotation as the slip/engagement member is rotated about the axis of rotation and does not engage the second adjustment member, and in the third position the slip/engagement member engages the second adjustment member to rotatably adjust the second adjustment member about the axis of rotation as the slip/engagement member is rotated about the axis of rotation and does not engage the first adjustment member.
