Brookfield introduces CD 152

The New Telephone and Telegraph Insulator.

The new Brookfield telephone and telegraph insulator, shown in the illustration, has been adopted by the American Telephone & Telegraph Co. and the Western Union Telegraph Co. It is being used generally on the lines of both companies. It is the result of many years of experimenting and is distinctive because of its great mechanical strength and its electrical efficiency.

The New Brookfield Insulator.

The new insulator is said to be giving excellent results on the long distance lines of the telephone company and is being used extensively by many railroad companies.

It is an interesting fact that the Brookfield Glass Co. sold the first screw thread insulator to the Western Union Telegraph Co. in 1865. The remarkable progress this company has made in developing types of insulators for practically every insulating purpose is best indicated, perhaps, by the constantly increasing demand for glass insulators, for both high and low voltage transmission lines, not only in this country, but in Canada, England, Italy, France and in South America.

The new plant of the Brookfield Glass Co. splendidly illustrates the permanency of the glass insulator industry. It is complete in every respect that makes for manufacturing efficiency.

Unlike many "essentials of electrical construction," Brookfield glass insulators have never passed out of the control of the family that conceived them. The business today is owned and managed by two of the grandsons of the founder of the Brookfield Glass Co.
