INSULATORS FOR TELEGRAPH AND TELEPHONE LINES.

 

In the accompanying cut we bring together a few figures of porcelain insulators for uncovered wires placed inside or outside of houses.

Figs. 1 and 2 represent simple and double channeled pulleys to be fixed against a wall, or upon a pole or a door post,

by means of nails simply. Fig. 3 shows a pulley of larger dimensions for iron wires. Figs. 4, 5 and 6 show perforated insulators, that are quite convenient for holding and supporting a wire, but which are not convenient to put in position when the wire is of some length. Fig. 7 shows a device for protecting a wire that passes through a wall. Fig. 8 shows a support designed especially for small poles. It may be used either by passing the wires through the aperture or winding it around the neck of the bell. Fig. 9 shows a cleft insulator designed especially for fixing a wire in places where it must form an angle.
