HYDRAULIC, STEAM AND ELEC TRIC POWER COMPARED. The Swiftest Elevators—The Greatest New Building in New York— The Eiffel Tower Elevators, . At present more than 4000 elevators are used daily in this city. The maximum speed of the fastest elevators which have ever built is 1500 feet a minute, a rate of one mile in three minutes and a frac tion. Sunol can do the distance, ac cording to her latest performance, in 2.08, while the railroad locomotive with a mile-a-minute speed is easily the leader. Passenger elevators, however, are like fast trotters and locomotives in this respect, that they do not always travel at top speed. With the modern elevator almost any speed desired can be obtained; it all de pends on the power used and the distance traveled. In a building which has a shaft of 250 feet—and they are few—a speed of 800 to 1000 feet a minute can be attained. On a rise of 150 feet it is easy to get a speed of 750 feet a minute with a weight of 1000 pounds aboard the elevator. In this city the fastest elevators are in the Union Trust Company's building, on Broadway, near Wall street. They can shoot up or down, carrying 3000 pound cargoes at a speed of 600 feet a minute. When tested with lighter weights they have traveled from 800 to 900 feet in a minute. But Mr. Brown says that in his opinion the average speed of elevators in office buildings in and around New York is 300 feet a minute. It is best adapted for work, and experience has demonstra ted that more passengers can be carried daily in a car going at that speed in the ordinary large building than at any other. In mines, where the run is long and frequently exceeds 1000 feet, the cages go up and down at a surprising rate, but there the power is supplied by larger winding engines. It is not unusual for such cages to spurt at the rate of a mile in every two minutes. To accomplish that a tremendous steam engine of 590 horse power would have to work at its best. The increase in the size of elevators goes on in keeping with the rapid im provement in other directions. The largest passenger cars in the world are now in course of construction across the Hudson at Weehawken under the super vision of Engineer Brown. These ele vators, of which there are three, are de signed to carry 135 persons on each trip. The cargo is equivalent to ten tons of freight. They will be owned by the North Hudson County Railway Company.
