Excerpt from Elevator Shaft Construction: Or Practical Suggestions for the Installation of Electric Elevators in Buildings In preparing this book, it has been the object of the author to present the subject treated in such a manner as to make the details of practical value to an architect, builder, or a building superintendent representing either, having a general knowledge of the work in and about elevator shafts. The principal aim and purpose of the work is to emphasize the necessity of the co-operation of all parties connected with the work of elevator shaft construction and elevator installation to produce the best results and necessary economy. The articles on elevator shaft doors and machine rooms contain information which it is hoped will be highly useful to architects in preparing their plans. It has always been, and still is, a difficult problem to determine the height of an elevator shaft bulkhead. The article pertaining to this subject has been made quite comprehensive, and the plates conform to the requirements of existing municipal regulations. The data and information contained has been gathered by the author in his own practice and systematized and generalized for the purpose of this work. As far as he knows, such data has never before been published and it is his hope that it will prove of considerable value to all interested in the subject. The author is under obligation to Albert Bauer of Brooklyn, N. Y., for much competent assistance. Information and drawings for special subjects have also been furnished by the Reliance Ball Bearing and Hanger Co.; Burdett-Rowntree Co.; Peelle Co.; Elevator Supply and Repair Co.; Peterson Engineering Co.; F. T. Ellithorpe; and Oscar A. Norman for the frontispiece; to all of whom the author tenders his thanks for their freely given assistance.

Excerpt from Hydraulic Elevators: Their Design, Construction, Operation, Care and Management The elevators so far considered are of the type known as low pressure, and are actuated with water pressures ranging between about 40 and 175 pounds per square inch. In the early days of hydraulic elevators the pressure was obtained by pumping water into a tank located upon the roof of the building, and as a column of water of one square inch cross section weighs about of a pound per foot of hight, the pressure seldom exceeded 50 pounds, and in many cases was as low as 30 pounds per square inch. With the advent of high buildings greater car speed was demanded, and this necessitated increasing the power of the elevator machine. This increase could be obtained in two ways, one by making the cylinder of larger diameter, and the other by increasing the pressure. As space in the buildings was valuable, the latter plan was adopted, and in order to obtain the increased pressure; a closed pressure tank was substituted for the open roof tank. The pressure tank had been used years before the time of high-power elevators, in buildings that were so low that the pressure obtained from an open tank on the roof was not high enough to keep the diameter of the cylinder within reasonable bounds; but from this time all elevators installed in high buildings were operated with water drawn from pressure tanks. The general introduction of the pressure tank resulted in an increase in the working pressure to from 75 to 100 pounds. By this increase the size of the cylinder, the tanks and the piping can be considerably reduced, with a corresponding saving in space and material. With the continued increase in the hight of buildings the pressure has been increased, so that at the present time it is common practice to use pressures up to 180 pounds and even a little higher.
