Excerpt from Elevator Service This travel has outgrown the extreme capacity of some of the best plants of elevators, and has indicated that, in spite Of great power and rapidity of operation, the passenger-carrying capac ity of an elevator actually decreases after a certain limiting point is reached, a condition which affects all types of elevators, and is the inevitable result of the combination of a certain num ber Of passengers with the number of floors to and from which they are carried. The important relation of elevator service to the success of all classes of buildings, renders it very desirable to determine the cause and character of this limitation, and to ascertain there from the best service which any elevator, or any combination of elevators, will afford, establishing an average or rated duty which may be adopted as a basis for the service to be expected from an elevator, or from any combination of units in an eleva tor service. The absence Of such a uniform definition Of the work of an elevator, has resulted in a confusing variety Of proportions, not only in the speed of the machines and in the size of the cars, but in the number of elevators of equal character applied to similar conditions of service.
