Harold W. Eaton - patent attorney

This Invention relates to machine tools, and more particularly to a headstock for use in grinding machines and the like. One object of this invention is to provide a simple and thoroughly practical headstock construction for a machine tool. Another object of the invention is to provide a machine tool headstock in which the face plate and center may be readily changed from a "live" center to a "dead" center. A further object of the invention is to provide a simplified headstock construction whereby manipulation of a single control member serves readily to shift the headstock from a "live" center to a "dead" center headstock.
