Abstract
An adjustable lens support assembly retains and supports a lens in fixed registration during the manufacturing process. The lens support assembly includes a plurality of adjustable spring-loaded lens retainer pins that enable a plurality of lenses of various diameters to be maintained therein. The adjustable lens retainer pins, preferably three (3) pins, extend upward from a circular base having a tapered upper surface. A spacer supports the base above the lens support arm a predetermined distance to provide sufficient clearance to permit of the operation a mechanism to pivot simultaneously the lens retainer pins. A lens pad is centrally disposed on the base to support the lens. When the lens is placed in the lens support assembly, the concave surface of the lens engages the lens pad and the outer edges of the composite lens engage the adjustable lens retainer pins. Each lens retainer pin includes a lower pin portion and an upper pin portion. The upper pin portion is mounted eccentrically to the lower pin portion. A pivot mechanism interconnected to the upper pin portion of each lens retainer pin enable the user to simultaneously pivot the upper pin portions to vary the distance be…
