FRED. M. LOCKE, of Victor, N. Y., manufacturer of the well known Locke insulator, has been successful in his legal controversy over the validity of his patents. Mr. Locke filed his application for letters patent in February, 1897, and on August of the same year, Mr. Boch, of the R. Thomas & Sons' Company, East Liverpool, Ohio, filed an application for the same thing. Interference proceedings have been pending since September, 1897, but the Patent Office has just decided that Mr. Locke was the first to conceive and reduce to practice the invention in issue.
