New Locke Catalog 1907 catalog

THE LOCKE INSULATOR MANUFACTURING COMPANY, Victor, N. Y., shows the development of electric power transmission during the two years since the issue of Its previous catalogue, No. 8, in "The Insulator Book" for 1907. This book takes up the matter of the revision of many of the company's insulator designs, the issue of a number of new designs, and the dropping from use of others. In compiling this catalogue the endeavor has been made to present data on only such material as has withstood the test of actual service.
