Cutter's Arc Insulator.

 

One of the sources of danger and annoyance in arc light work lies in the grounding of arc lamp frames, especially in damp weather. In planning to avoid existing defects, George Cutter, whose latest device is shown in the accompanying illustration, seems to have combined the good qualities which a device of this sort ought to have. He gives the body of his insulator the form of a double petticoat bell so as to lessen the chances of water creeping

across and also to increase the surface resistance. Instead of using glass or porcelain he makes this insulating bell of hard rubber, which is less apt to have a film of moisture form on its surface. The screw eye at the top and the snaphook at the bottom are both threaded into strong bushings moulded into the rubber, all parts being planned for ample strength. The completed device is but twice the size of the illustration. It is made and exploited by George Cutter of Chicago.
