Now if you are thirty or forty feet away from the engine
and the governor belt slips, or gets unlaced, or the pulley gets off,
about the first thing the engine would do would be to jump out of the
belt and by the time you get to it, it will be having a mighty lively
time all alone. This might happen once and do no harm, and it might
happen again and do a great deal of damage, and you are being paid to
run the engine and you must stay by it. The governor is not a difficult
thing to handle, but it requires your attention.
Now if I should drop the governor, you might say that I had not given
you any instructions about how to regulate it to speed. I really do not
know whether it is worth while to say much about it, for governors are
of different designs and are necessarily differently arranged for
regulating, but to help young learners I will take the Waters governors
which I think the most generally used on threshing and farm engines.
You will find on the upper end of the valve or governor stem two little
brass nuts. The upper one is a thumb nut and is made fast to the stem.
