THE GOULD AND WATSON COMPANY, BOSTON. — On page 561, of our issue of November 19th we illustrated the new Cushing switchboard for electric lighting in theatres, and we desire to call more particular notice to the moulded mica insulating material of which the insulating parts of this board were made. Messrs. J. P. Cushing & Co., who manufactured the board, gave a great deal of attention and preliminary experiments to the selection of this material, and it was found that moulded mica was the most suitable of any material experimented with, it being extremely hard and strong, perfectly waterproof and fireproof. Undoubtedly this material is coming rapidly to the front as a reliable and durable insulator, and its merits ought to be thoroughly investigated by all manufacturers of electrical apparatus. · · |
