Combined Strain Insulator and Sign

| Combination Car Stop Sign and Strain Insulator |
A COMBINATION strain insulator and sign is being manufactured and distributed by the American Porcelain Company, East Liverpool, Ohio. This insulator is intended for the replacement of the iron, enamel or wooden signs which are commonly used by electric railways and attached to span wires. The porcelain sign is made of the same material as are electrical insulators. The sign lettering is fired under the glaze, which makes the part acidproof and insures long life. This type of insulator has been adopted by several of the railways in Ohio as stop signs.
