An Ingenious Insulator.
The insulator shown in the illustrations herewith is the invention of Mr. J. C. Berrang, of Asbury Park, N. J. Its object is to provide a simple, cheap and neat device for stringing wires. In insulators heretofore constructed, it has been necessary to provide a tie wire, or take a complete turn of the main wire around the insulator, which is not only an unsightly arrangement, but also makes it almost impossible to string the wires taut. In this arrangement the tie wire is entirely dispensed with, and the wires can be drawn taut and held in place in one-half the time and with less trouble than in the old way. As will be noticed, the insulator is composed of four parts, the two insulating blocks, the screw and the plate, the latter being held between the insulating blocks and having diametrically opposite extensions provided with vertical retaining arms, which firmly hold the wire as shown.
The blocks and plate are held together by a single screw, which also secures the insulator to its support in the usual manner.
A large number of practical electricians have expressed a favorable opinion of this arrangement, and It is likely to take the place of the ordinary insulator to a great extent, as it can be manufactured very cheaply and will save a great amount of time and labor. The inventor of this ingenious device, Mr. Jacob C. Berrang, is with the Asbury Park Electric Light and Power Co., and the patent has just been issued.
