Excerpt from Indicator Practice and Steam-Engine Economy: With Plain Directions for Attaching the Indicator, Taking Diagrams, Computing the Horsepower, Drawing the Theoretical Curve, Calculating Steam Consumption, Determining Economy, Locating Derangement Ok Valves, and Making All Desired Deductions, Also Tables During the past two years I have written several short articles for the American Machinist on the subject of the indicator-diagram. In these there was not much attempt at connection, or intention to cover more than a few points as they came up from time to time. As an outcome of the appearance of these articles I have received many letters of inquiry, especially from engineers in charge of steam engines and boilers of various classes. These letters, very frequently leading to considerable correspondence, have largely guided me in the preparation of this work: it seemed a fair presumption that they indicated what would be acceptable to others similarly situated. It has been my aim to present the subject comprehensively enough to enable any engineer to apply the indicator to his engine, take the diagram, and make all necessary calculations from it. The endeavor has been to use no terms except such as are generally understood or fully explained, and no mathematical demonstrations are given or are required that involve the use of anything but simple arithmetical calculations.
