PREFACE
This book on Steam Engines was written to be used as a text-
book for correspondence students in the University of Wisconsin
Extension Division. It is the third of a series of three textbooks
designed for those students who are pursuing a general course in
Steam Engineering, the other two being "Steam Boilers" and
"Heat."
In this course in Steam Enginesweaimtoteach thefundamen-
tal principles underlying the operation of the steam engine and
to do this in as simple and nonmathematical a manner as possi-
ble. This is particularly true with those parts which deal with
thermodynamic principles. Enough of the practical features
of steam engine operation has been given to illustrate the princi-
ples, and it is hoped that operating engineers who take this
course will be able to supplement from their own experience
other applications of the principles presented.
That part of the course dealingwith valve gears has beenmade
more complete than other sections because our experience shows
that operating engineers usually do not understand the valve
gear mechanism of their engines as well as they do other parts.
Most of the material in the chapter on Lubrication was fur-
nished by Mr. R. P. Tobin, Chief of the Technical Department
of the Vacuum Oil Company and we take this opportunity to
express our thanksforhis aid. We wish to takethis opportunity
also to thank Mr. J. C. White, Chief Operating Engineer forthe
State of Wisconsin for very valuable suggestions as to the scope
of the courseand theoutline to be followed, also for many useful
hints and suggestions about writing the course, and for a care-
ful and critical reading of the manuscript.
