A New Insulator Pin
IN the description of the transmission line and third-rail system of the Long Island Railroad in the July number, attention was called to the new type of iron insulator pin employed. This pin, which is a radical departure from previous practice in pin design, is the invention of W. N. Smith, of Westinghouse,
Church, Kerr & Co., of New York. Mr. Smith has applied for a patent on the device. The design has been further improved, and arrangements are now being made for manufacturing and placing it on the market, under the name of "The Smith-Grip Insulator Pin."
