ALEXANDRIA, Va., April 16 -- Jesse G. Cogswell of Torrance, Calif., has developed a blade ring saw blade.
According to the U.S. Patent & Trademark Office: "A flat-sided annular blade for a blade ring saw for cutting hard material such as tile along straight paths and curved paths in which the workpiece is moved through the central portion of the blade. In addition to the usual sintered abrasive diamond coating on the outer peripheral portion of the blade, the inner peripheral portion preferably is tapered to a curved inner edge and also is coated with an abrasive, preferably an electroplated diamond coating providing smoother sawing operation and a finishing action on the workpiece."
