When a job is about finished you will see him cleaning
his ash pan, getting his tools together, a good fire in fire box,
in fact all ready to go, and he looses no time after the belt is
thrown off. He hooks up to his load quietly, and is the first
man ready to go.
*Q. When the piston head is in the exact center of cylinder, is
the engine on the quarter?
*A. It is supposed to be, but is not.
*Q. Why not?
A. The angularity of the rod prevents it reaching the quarter.
*Q. Then when the engine is on the exact quarter what
position does the piston head occupy?
A. It is nearest the end next to crank.
Q. If this is the case, which end of cylinder is supposed to be
the stronger?
A. The opposite end, or end furtherest from crank.
Q. Why?
A. Because this end gets the benefit of the most travel, and
as it makes it in the same time, it must travel faster.
*Q. At what part of the cylinder does the piston head reach
the greatest speed?
A. At and near the center.
*Q. Why?
Figure this out for yourself.
*Note. The above few questions are given for the purpose of getting
you to notice the little peculiarities of the crank engine, and are not
to be taken into consideration in the operation of the same.
