Properly Use the Air Brake.
A travelling schoolhouse is one of the
euriosities of modern railroading. 1t is
a queer schoolhouse, and it cost $4,000
to build. 1t is filed with levers, air
chambers. cylinders, whistles, gauges,
valves, cords and pipes, and at one end
Is an upright steam boiler and air
pump, used in COMPRISING the air with
which the apparatus is operated.
No children attend this school. Many
Of the pupils are grzzled, grimy veter-
ans. who have been railroading for
years. Others are younger men, and
there is a sprinkling of boys from IS
years old up. They are taught by a reg
ular professor, a graduate of me-
chanical college. His pupils have no
books. They listen while he talks and
watch while he demonstrates the work
ings of the air brake. His classes are
usually held from nine till eleven o'clock
in the morning and from seven till nine
o'clock at night, so that he can have for
pupils the railroad men who have re-
Gently come in off their runs.
The air brake is the one subject
taught. From IS to 25 pupils will
crowd into the small space on the side
of the middle of the room not occupied
by apparatus. The professor is usually
in his shirt sleeves and bareheaded, for
the atmosphere in the room is always
| from 90 to 10 degrees, made so by the
steam boiler. The professor has only
one book, and while he is delivering his
| lectures and talking about the POSSIBLE
ties as well as the troubles of the air
brake he keeps this book in the hip
pocket of his trousers. After his lee
| ture is over he takes it out, and it is then
found to be only a small blank book.
| In this he writes the names of the MEM
bers of the class before him. He will
then question the pupils, and jots down
| opposite each name the percentage of
correct answers given. Any who fall
below a certain mark have to come
back to school tor another lesson. Some
times it takes three or four lessons
to teach a man the principles Of the
air brake; sometimes man will thor
oughly understand the intricacies of
| the system at one lesson.
The apparatus represents a locomo-
tive and a train of II cars. Each car
is represented by an air cylinder The
| professor shows how easy it is by the
proper manipulation of the engineers
lever to put all the brakes on at once
| and to release them all at once. He
then shows how unskilled engineers
can and often do release one or two
brakes at time. thus affecting the eff
ficiency of the service. He illustrates
the emergency application, in which the
entire II cars have their brakes set in
one second by the watch.
