Separable Thimble Pins for Insulators


A DECIDED disadvantage of the all-metal pin has heretofore been the necessity of cementing the entire pin in the insulator, which, necessarily done in the field, results in poor execution and much expense. Cementing the pin in the insulator at the factory has not been practicable on account of the difficulty of shipping.


This illustration has not been processed yet.


All these difficulties are overcome by the form of pin here shown. These pins, made by the Locke Insulator Manufacturing Company, Victor, N. Y., consist of an iron base, a threaded iron thimble and a steel bolt. The small thimble is rigidly and accurately cemented in the insulator by skilled workmen at the factory and when the insulator is received along the line, it is necessary only to screw the bolt into the thimble, when the whole is ready for erection on the cross-arm. The pins are made in six sizes.
