The "Victor" Split Insulator and Hanger.
The E. S. Greeley & Co., of this city, have recently brought out a novel split insulator which seems applicable to a variety of line work. The insulator, known as the "Victor," is shown in Fig. 1. It is provided with an opening to accommodate the largest wire and it has a perfectly smooth bearing and locking lugs that prevent torsion of the two parts after they are bound together. For this purpose a special hanger is furnished in two sizes, 2 inches and 6 inches in length respectively. This consists, as shown in Fig. 2, of No. 14 galvanized wire twisted together, except at the ends which surround the insulator. The ends are long enough to encircle the insulator twice, after which they are twisted together, as shown.
The uses to which these split insulators can be put are apparent. Being in two parts, they can be placed upon a line already erected equally as well as upon a new one; and they are specially adapted for taking up sag, for guys and "hauling off " purposes. Another use to which they can be applied is the increase of the capacity of crossarms by suspending them beneath, and hence they are also specially adapted for the suspension of wires under elevated railway structures and in tunnels.
The illustration, Fig. 3, shows the new split insulator applied as a circuit breaker for arc circuits, and Fig. 4 shows its application as a tree insulator.
