Insufficient lead will not allow enough steam to enter the cylinder
ahead of piston to afford cushion enough to stop the inertia, and the
result will be that your engine will pound on the wrist pin. You most
likely have concluded by this time that ‘lead’ is no small factor in the
smooth running of an engine, and you, as a matter of course, will want
to know how you are to obtain the proper lead. Well don”t worry
yourself. Your engine is not going to have too much lead today and not
enough tomorrow. If your engine was properly set up in the first place
the lead will be all right, and continue to afford the proper lead as
long as the valve has not been disturbed from its original position; and
this brings us to the most important duty of an engineer as far as the
engine is concerned, viz: Setting the Valve.

Now there are two ways to read this book, and if I know just how you had
read it I could tell you in a minute whether to take hold of an engine
or leave it alone. If you have read it one way, you are most likely to
say ‘it is no trick to run an engine.’ If you have read it the other way
you will say, ‘It is no trouble to learn how to run an engine.’ Now this
fellow will make an engineer, and will be a good one. He has read it
carefully, noting the drift of my advice. Has discovered that the
engineer is not expected to build an engine, or to improve it after it
has been built. Has recognized the fact that the principle thing is to
attend to his own business and let other people attend to theirs. That
a monkey wrench is a tool to be left in the tool box till he knows he
needs it. That muscle is a good thing to have but not necessary to the
successful engineer. That an engineer with a bunch of waste in his hand
is a better recommendation than an ‘engineer license.’ That good common
sense, and a cool head is the very best tools he can have. Has learned
that carelessness will get him into trouble, and that to ‘forget’ costs
money.

If you have not read the preface on the preceding pages, turn back and

20070924 16:04

read it
If you have not read the preface on the preceding pages, turn back and
read it. You will see that we have stated there that we will use no
scientific terms, but plain every day talk. It is presumed by us that
there will be more young men, wishing to become good engineers, read
this work than old engineers. We will, therefore, be all the more plain
and say as little as possible that will tend to confuse the learner, and
what we do say will be said in the same language that we would use if we
were in the field, instructing you how to handle your engine. So if the
more experienced engineer thinks we might have gone further in some
certain points, he will please remember that by so doing we might
confuse the less experienced, and thereby cover up the very point we
tried to make. And yet it is not to be supposed that we will endeavor to
make an engineer out of a man who never saw an engine. It is, therefore,
not necessary to tell the learner how an engine is made or what it looks
like. We are not trying to teach you how to build an engine, but rather
how to handle one after it is built; how to know when it is in proper
shape and how to let it alone when it is in shape. We will suppose that
you already know as much as an ordinary water boy, and just here we will
say that we have seen water haulers that were more capable of handling
the engine for which they were hauling water, than the engineer, and the
engineer would not have made a good water boy, for the reason that he
was lazy, and we want the reader to stick a pin here, and if he has any
symptoms of that complaint, don”t undertake to run an engine, for a lazy
engineer will spoil a good engine, if by no other means than getting it
in the habit of loafing.

An authority says, ‘Bring your engine to a dead center and then adjust
your valve to the proper lead.’ This is all right as far as it goes, but
how are you to find the dead center. I know that it is a common custom
in the field to bring the engine to a center by the use of the eye. You
may have a good eye, but it is not good enough to depend on for the
accurate setting of a valve.

If the injector is so hot that it will not lift the cold water, there is

no way of cooling it except by applying the water on the outside
If the injector is so hot that it will not lift the cold water, there is
no way of cooling it except by applying the water on the outside. This
is most effectively done by covering the injector with a cloth and
pouring water over the cloth. If, after the injector has become cool,
it still refuses to work, you may be sure that there is some obstruction
in it that must be removed. This can be done by taking off the cap, or
plug-nut, and running a fine wire through the cone valve or cylinder
valve. The automatic injector requires only the manipulation of the
steam valve to start it. There are other makes that require, first: that
the injector be given steam and then the water. To start an injector
requires some little tact, (and you will discover that tact is the
handiest tools you can have to make you a good engineer). To start an
injector of the Pemberthy type; first give it sufficient steam to lift
the water, allowing the water to escape at overflow for a moment or long
enough to cool the injector, then with a quick turn shut off and open up
the supply which requires merely a twist of the wrist.

Q

20070915 10:04

Q. How do you find the speed of a piston per minute?
A. Double the stroke and multiply it by the number of
revolutions a minuet. Thus an engine with a 12 inch stroke
would travel 24 inches, or 2 feet, at a revolution. If it made
200 revolutions a minute, the travel of piston would be 400 feet
a minute.

Your engine may however act very queer some time, and you may find the

20070914 10:03

eccentrics in their proper place
Your engine may however act very queer some time, and you may find the
eccentrics in their proper place. Then you must go into the steam chest
for the trouble. The valves in different engines are fastened on valve
rod in different ways. Some are held in place by jam nuts; a nut may
have worked loose, causing lost motion on the valve. This will make
your engine work badly. Other engines hold their valve by a clamp and
pin. This pin may work out, and when it does, your engine will stop,
very quickly to.

When I started out to talk engine to you I stated plainly that this book
would not be filled up with scientific theories, that while they were
very nice they would do no good in this work. Now I am aware that I
could have made a book four times as large as this and if I had, it
would not be as valuable to the beginner as it is now.
