Ofcourse it is thoroughlv insulated. As illustrated, one linecarries its trolley direct, while the cross-line is made to WORTHINGTON PUMPS AT THE WORLDSFAIR. THE almost incredible amount of water necessary toslake the thirst of the various steam plants at theExposition will be furnished by Worthingtonpumps, made by the world-known manufacturers of thatname, at Liberty street. New York. In the pump-houseat the Worlds Fair there are, therefore, four pumps withan aggregate capacity of 40 million gallons per diem,against a pressure of 100 pounds per square NEW TROLLEY HANGER. support the fixture. A pair of arms automatically passaround one trolley wire, allowing trolley to pass whilestill receiving current from its own—the other wire. Inshort, the crossing combines those principles most neededwith positive action, while the first cost is not great. Another device manufactured by the same firm, theEmerson Electric Manufacturing Companj-, St. Louis, istheir new trolley hanger, which, while less expensivethan many on the market, is fully equal in appearance toothers, and is said to be stronger. The insulation is per-fect, a short circuit being impossible.
