Excerpt from Boilermaker's Assistant in Drawing, Templating, and Calculating Boiler Work and Tank Work: With Rules for the Evaporative Power and the Horse Power of Steam Boilers, and the Proportions of Safety-Values; And Useful Tables of Rivet Joints, of Circles, Weights of Metals, Etc I have had pleasure in revising and editing ilir. Courtney's notes, here following. They bear the impress of good practice and experience and, simple and unpretending as they are, they will come home to the understandings of thoughtful workmen. The problems, which hare been selected with judgment, and the rules, which are expressed with simplicity, will be directly useful to the practical boilermaker, and will supply just what he requires for calculating his quantities, constructing his diagrams, and shaping his templates. At the same time, he will be enabled, when called upon to do so, to proportion the rivet-joints and also to settle the dimensions of boilers, according to the pressure at which they are to work, and the power that is to be required of them.
