Conover's insulator

Conover's Insulator.

In the accompanying cuts are shown views of an insulator devised by Chauncy E. Conover of Cincinnati, O. They may be made of glass or porcelain. Fig. 1 is a top view, Fig. 2, a side elevation, and Figs. 3 and 4 are respectively a top view and side elevation of a modified form.

In Figs. 1 and 2 a central hole furnishes means for securing the insulator upon a pole, cross bar, or other object, and in Figs. 3 and 4 two holes are provided.

A groove or seat for the line-wire is provided, over which groove ears are projected, one upon each side of line wire groove. The extensions are not placed directly opposite each other, one being forward of the other in the direction of the line wire leaving a groove or space between the ears diagonal with the line wire groove. This diagonal groove is made a little larger or wider than the wire to be used thus enabling it to be placed in the insulator by giving to the wire a slight bend in the direction of the groove without making a permanent bend, and also while the wire is drawn comparatively tight. The line wire will, as soon as it is below the angular projection of the ears, assume its position in its groove or seat, while the angular projections retain it. The wire can be quickly inserted or removed and requires no other fastening.

By means of the construction shown in Figs. 1 and 2 the advantages of the old form of insulator are retained, with the additional advantage of the line wire seat, thus taking the weight of the line wire from the tie wire and at the same time obviating the use of a tie wire on every insulator, thereby effecting a saving in the amount of tie

wire required, as well as a saving in the time used in fastening it upon the insulator.

The line wire can be pulled tight before placing it within the insulator and be put in while tight instead of threading it through a hole and pulling it tight afterward. Moreover a secure seat is provided for the support of the line wire regardless of any tying wire. The modification shown in Figs. 3 and 4 may be used in a horizontal or perpendicular position
