An Efficient Insulator.
The Hemingray Glass company of Covington, Ky., has placed upon the market an insulator, a cut of which is presented herewith, and which possesses many points for consideration. It is made of glass, and is provided with a series of teeth at the lower edge of the insulator shield to attract and gather at their points drops of water running down the outer surface. The advantages of such a construction are evident, and the company is making preparations to push the sale of this specialty in all portions of the country. The device is fully protected by patents.
