The Elmer, N. J., Glass Co. are operating five shops on each shift on insulators. They have three machines, the invention of Thos. Duffield, in which a large production can be made. The machine is entirely different from the average press used in insulator factories. Maurice Davis, of Bridgeton, is president of the company, and Dan Parker, of the same town, general manager.
