Thompson-Brown Guard Wire Insulator With Cast Iron Holder

Thompson-Brown Guard Wire Insulator.

We illustrate in the accompanying engraving a new guard wire insulator which is being introduced by the Thompson-Brown Electric Co., of Boston. It is made of vitrified porcelain and malleable cast iron, the guard wire passes through the center of the insulator, while the supporting wires pass over the bracket and underneath the insulator, which is made in two halves to that it can be easily applied at any part of the line. This guard wire insulator forms another link in the very complete set of overhead line material recently got out by the Thompson-Brown Co., and being' so simple and cheap, will readily recommend itself to all electric railway engineers.
