Table of Contents

Some two years ago the author commenced collecting memoranda of mechanical and practical information pertaining to the care and operation of steam engines and boilers, with a view of forming a systematic digest.

Being an employee of the J. I. Case Threshing Machine Co. for a number of years my attention was called to the constant inquiry for a book of this description from young men mechanically inclined and those running farm engines and small steam plants.

By repeated assurance that there was great need for such a work, and by ready and valuable assistance from personal friends and experts in mechanical engineering, I have considered it advisable to publish a practical guide for young engineers.

The aim has been to place the information contained in the book in the most simple and compact form, and while it is not intended for the education of the more advanced engineers, the instructions given will be found practical in the operation of steam plants of any size. It is more especially intended for the instruction and guidance of young men learning to run engines, and those operating farm engines and small plants, whose experience has been limited.

After carefully considering the mode of presentation, it was thought best to adopt the form of a catechism, with the questions and answers so set forth as to resemble an ordinary conversation; also to illustrate and give a minute description of the construction and function of the different parts used in the building of engines and boilers.

While the greater part of the information is new, parts have been compiled from Power, Roper and other mechanical papers and books, simplified to meet the required aim, for which due acknowledgement is here given.
