ABSTRACT:
Interchangeable faceting apparatus comprises a reversible dual indexing mechanism consisting of a primary indexing gear with a small number of notches and an auxiliary indexing gear controlling the primary gear, and a height adjusting mechanism which permits a faceter frame to be precisely positioned with respect to the lap surface at any height of the faceter frame. The primary indexing gear with a relatively small number of notches engaged by a spring trigger provide subdivided indexes by the action of the auxiliary indexing gear.
