It emphasizes shop-ready application rather than purely theoretical study, using practical explanations tied to everyday layout jobs. It introduces core methods such as orthographic projection and triangulation, then expands into detailed layout procedures for major boiler types, including rules for sizing, shaping, and assessing

YORKTHE BOILER MAKER  \n17 Battery P1ace  \n1907  \n2  \n③  \nS427817  \nReprinted from  \nCopyrighted,1907  \n# PREFA CE\n\nThis book has been compiled for the purpose of givingthe practical boilermaker the information necessary to enablehim to lay out in detail different types of boilers,tanks,stacksand irregular sheet netal work.While the vork of laying out,as it is carried on in the boiler shop,requires considerabletechnical knowledge in addition to that gained by a practicalmechanic in the course of his experience in the shop,yet acomplete mastery of such subjects as geometry,mechanicsand similar branches of elementary mathenatics is notessential for doing the work.For this reaso11 no attempt hasbeen made to present these subjects separately from a theo-retical standpoint.The practical application of certain ofthe principles involved in these subjects is,however,veryimportant,and this has been explained in a practical way inconnection with different jobs of laying out which form a partof the every-day work in every boiler shop.Only those lay-outs which are of imnediate material use to boilermakers aredescribed,and as far as possible the minor details are givenso as to make each problem conplete.  \nThe first two chapters explain the methods of laying outby orthographic projection and triangulation,since these arethe two principal methods used in solving any problen inlaying out.A few simple problems are given in each casefrom which the application of the methods to more compli-cated problems may be learned.The chapters which takeup the detailed layout of different types of boilers give notonly the methods for laying out the actual boiler but also therules for determining the size,shape and strength of thedifferent parts.-These computations are given more indetail in the case of the plain tubular boiler since the problemsinvolved in this case are general and may be applied to almostany other type of boiler.1  \n# TABLE OF
