IMPROVED INSULATOR

 

Clarence Humphrey has recently received a patent for an improved insulator, a model of which he and his brother, O. J. Humphrey, got out some time since, for telephones and other electric wires. The insulator is entirely of glass and needs no extra wiring to attach the electric wires to it. The wires can be attached and loosened or tightened with the turn of the hand.
