Another Electrical Fire Engine. Frank Irving of the Franklin Electric Company, Passaic, N. J., is at work on a model of an electrical fire engine. He claims that it is practicable to build an engine which witl propel itself over the streets to the scene of a fire and there work the pumps. His idea is to substitute a storage battery for the furnace and boiler now in use on steam fire engines. The Franklin storage battery is to be used, patented by Mr. Irving. Mr. Irving feels fully satisfied that with a battery of less bulk and no more weight than the boiler and furnace now in use on steamers he can store away enough electric energy to drive an engine two miles over any streets fit for wagon use and to run the pumps steadily for six hours afterward.
