ABSTRACT:
A support assembly including elongated upper and lower parallel plates. A plurality of column supports separate and interconnect the parallel plates. A clamping assembly is supported by the plates, the clamping assembly having vertical and horizontal pressure screw assemblies. A vertical pressure screw assembly is mounted upon the upper plate adjacent each end thereof, and a horizontal pressure screw assembly is mounted upon the lower plate at each end thereof. Both vertical and horizontal pressure screw assemblies project into the space between the upper and lower plates. An annular flexible platform is attached to the lower plate adjacent each end thereof, beneath each vertical pressure screw assembly, and projects into the space between the plates. Lenses, which are to be fixed together by adhesive means to form a combination lens, are received upon a flexible platform, aligned by action of a horizontal pressure screw assembly, and pressed together by action of a vertical pressure screw assembly. A utility rack for holding individual lenses prior to assembly into a combination lens is attached to the support assembly.
