GILBERT'S NEW TELEGRAPH WIRE BINDER.
THE main objects of this Wire Binder, the invention of Mr. Gilbert, of the Dundee and Arbroath Joint Railway, are: —
1st. To facilitate the erection and taking down of telegraph wires.
2nd. To reduce friction at the insulators, and the consequent breakages of the wires which occur with the ordinary wire binder.
3rd. To reduce surface contact of wires with insulators, and thereby to diminish the leakage of current in damp weather.
As will be seen from figs. 1 and 2, which represent respectively the elevation and plan of an insulator with the new binder attached, the latter is of a bow shape. It is constructed of malleable iron, and has its free ends hooked so as to embrace or grip the wire some inches on each side of the insulator. It can be applied to any insulator having a side groove, and by the most inexperienced workman in a few seconds.
