The new high resistance glass insulator shown in the cut was invented by Foree Bain, of Chicago. The insulator is made of unusual strength and intended for heavy work, such as carrying feeders for electric railways. The corrugations which are made both outside and inside of the apron increase the distance from the wire to the pin fully 100 per cent., and, it is claimed, that water in passing over the edges of the rings will become thin and broken, and on reaching the inside of the glass will drop off instead of creeping over the inner obstructions to the pin.
Another advantage claimed for this form of insulator is that the many surfaces will reflect the light under the glass in such a way as to keep insects out, obviating a source of much annoyance where plain dark glass is employed. The insulator is introduced by the Central Electric company of Chicago.
