Locke patent for glazeweld insulator

A New Porcelain Insulator.

Fred M. Locke, of Victor, N. Y., the well known inventor and manufacturer of porcelain insulators for high-tension lines, has just been granted a patent on the new type of insulator which is illustrated herewith. As will be seen from the drawing, the insulator is composed of several parts and so constructed as to prevent any leakage of current over the insulator to the support, and thereby obviate the burning off of the pin. The inner petticoat extends down to a point adjacent to the crossarms, upon which the pin is mounted, to serve as a protecting sleeve for the pin and to increase the arcing distance of the current around the insulator.

The insulator is composed of several shells which are coated with a layer of slip or glaze, then nested together and baked in a kiln, so as to form practically a single piece. The central petticoat is composed of two parts joined in this way. The seam of glaze between the shells, it is claimed, will resist the escape of the current.
