THE LIEB OVERHEAD WIRE CONSTRUCTION.

THE accompanying illustrations show two forms of construction employed by the Lieb Machine Works, of this city, in overhead electric railway work.

Fig. 1 — Overhead City Construction.

In Fig. 1 is seen the method used in city lines. Here the Lieb insulated turn-buckle not only plays the part of a perfect insulator of great length and strength, bat it also entirely obviates the necessity of a pole ratchet. All the slack necessary can be taken up with the turn-buckles, and the span-wire, being insulated from the trolley by the insulated hanger and from the poles by the insulated turn-buckle, a double insulation is thus secured. This insulated turn-buckle, like the wooden insulator, can be used in various ways to make combination appliances for line work.

Fig. 2 — Overhead Suburban Construction.

Fig. 2 shows one of the many ways in which the Lieb wooden insulators can be applied in line construction. In this case the trolley-wire bell usually employed is entirely dispensed with, and a metal piece substituted for it. The first cost is thus greatly reduced. The outer ends of the span-wire are thoroughly insulated, the small section only between the wooden insulators being alive.

For suburban work, where there are few telegraph wires, this construction has been found wholly satisfactory.
