Ingenious Use of Fire Engine
An ingenious use of material which at first glance would seem to be valueless is shown in the accompanying illustrations of a fire engine used in connection with a portable transformer outfit belonging to the municipal lighting plant of Crawfordsville, Ind. This emergency outfit proved itself of great utility for testing trial Power installations, break-down service and for temporary installations at country fair and similar services. The running gear was originally part of one of the fire engines owned by the city. When the engine was scrapped, to be replaced by more modern equipment, the wheels and frame were secured by the superintendent of the electric light plant. The electrical equipment consists of two Westinghouse single-phase distributing transformers, each of 25 k. w. capacity. Leads are brought out to the rack so that cither single-phase or polyphase current can be obtained at potentials of 110 and 220 volts.
