THE "CINCH" INSULATOR.

The "Cinch" trolley wire insulator, shown in the accompanying illustration, has many distinct advantages, which have won for it the unqualified approval of every practical man who has seen it. The insulating material is comb stock rubber, the stem and yoke are of malleable jet iron, and the pin is of brass. The strains on the insulating material are solely those of compression. There are no screw threads, or other parts subject to deterioration from exposure. The wire pin is more perfect in its details than any similar pins that have heretofore been introduced. The objects aimed at in the design of this insulator are, great strength, high insulation, small size, convenience, durability and cheapness. This insulator is manufactured by Messrs. Emmet Bros. & Griswold, 150 Broadway, New York, who will send samples free to any one wishing to examine it.
