The new NOTI (no tie) insulator is announced.

New Insulator.

The device illustrated and described herewith is a new form of insulator, for which a patent has been granted to Albert Vickers and William Dibb of Syracuse, N. Y. The insulator is designed to do away with tie-wires, and consists of a body of the present form, screwing to the pin with a top provided with a cavity shaped as shown in Figs. 1 and 2, and having two opposite recessed slots. The wire is laid in the grooves, and a plug of the same material as the insulator, shaped as shown in Fig. 3, is pushed into the cavity. This plug holds the wire against one wall of cavity, bending it very slightly, as shown in Fig. 4. It will be seen that the roller action of the plug prevents the wire from moving laterally; that the lugs keep it from flying up, and that it is therefore securely fastened. The plug cannot come out, for the pressure of the wire against the slight groove in it holds it to its place securely enough, as there is no strain on it tending to force it out. The advantage of this form of insulator is that the wire rests on nothing but smooth surfaces of glass or porcelain, so all chance of abrasion or mechanical injury is prevented. It is held to the insulator more securely than even a tie can hold it, and all the corrosion scratching due to tie-wires is entirely done away with. It is evident, therefore, that broken wires and crossed lines will be reduced to a minimum on lines where this insulator is used, to say nothing of the very much less time required to construct a line with them, and the securing of a perfectly uniform fastening at every insulator, and one which can be readily inspected from the ground. This insulator is being put on the market by the Noti Insulator company of Syracuse, N. Y., and is made for any size wire.
