Abstract
An adapter for holding a lens blank and lens block assembly in a fining and polishing apparatus includes an adapter body having a non-circular socket extending inwardly thereof from one face for receiving a correspondingly shaped projection on a lens block. A central recess in the other face of the adapter body receives a pin on a spindle pressure arm. The non-circular socket provides a reference axis corresponding to the base line for the lens block. Guide rods extend outwardly from the outer periphery of the adapter body parallel to the reference axis for cooperation with a locating rod in a fining and polishing apparatus for maintaining the proper orientation of the lens blank during processing. Apparatus for mounting lens blanks in a desired rotated position includes a plate attached to a spindle pressure arm and having a guide arm extending outwardly therefrom for pivotal movement about a vertical axis. A pointer and indicia on the upper face of the plate are provided for indicating the angular adjustment of the guide arm. A locating rod extending downwardly from the outer end portion of the guide arm cooperates with guide rods associated with the lens blank for maintaining the desired rotated orientation of the lens blank during processing.
