Locke's Steel Insulating Pin and Insulator.


For overhead line construction Frederick [sic] Fred M. Locke of Victor, N. Y., has brought out the excellent appliances shown in the illustration. He has designed an indestructible insulating pin supplied with a steel bolt passing from the top of the pin through a half-inch hole in the cross-arm and securely fastened on the under side by a nut and washer. The iron cap between the top of the insulator pin and the cross-arm serves as a brace to resist the strain of the pull on the pin, thereby keeping out water and moisture and preserving the arm.
