Trolley Guard Insulator.

The accompanying engraving shows an insulator for trolley guard wires manufactured by the Hammond Cleat & Insulator Company, of Boston. This insulator is made of one piece of porcelain, and mostly for appearance's sake is japanned black. Of course, japan being also an insulator, it will be readily seen that the guard wire is thoroughly insulated. The Illustration of this device shows it so well that further explanation of its uses is needless. It might be well to state, however, that the only metal part in connection with it, the hooks and nuts, are galvanized so as to withstand the weather. This insulator is made to serve the purpose of a strain insulator, if it should be necessary to put it to this use.

The managers of the West End Street Railway Company, of Boston, Mass., have thought so well of this insulator that they have placed an order with the Hammond Cleat & Insulator Company for 1,000.
