Description:

This duplicator uses a template that is "scanned" by a jet of fluid, "so that variations in the shape of the template causing corresponding changes in the fluid discharged from the nozzle, which changes in turn control the positioning of the tool relative to the work piece." We have seen this patent number listed on a Monarch lathe.
