ABSTRACT:
In a gemstone blocking or polishing machine, a stone holder is supported in a gimbal so that it can pivot about two perpendicular axes, the holder also being capable of rotation about its own axis. The outer ring of the gimbal is in the form of a gear ring which can be indexed, and the holder passes through a slot in a grain ring which controls the orientation of the holder and can be locked to the gear ring by a clutch. In order to change the facet, the gear ring alone is indexed, forcing the holder to twist about its axis. In order to change the grain orientation, the gear ring and the grain ring are indexed synchronously. In order to signal when the facet has been worked to a sufficient depth, an electrical contact is made between the top end of the holder and a horizontal contact bar. The position of the holder is controlled by a spring.
