No. 10. SECOND BITUMINOUS DISTRICT. 283
The tanks for storing the air are 14 feet and IG feet long, respectively
and 29 inches in diameter, holding 130 cubic feet of air and
are designed to work under 750 pounds pressure.
The air from the two main tanks is conducted through a reducing
valve to an auxiliary reservoir placed below and between them, and
from which it passes through the throttle valve to the cylinders. In
l»assing through the reducing valve, the pressure of the air is reduced
from 750 pounds per square inch to 140 pounds per scjuare inch. This
valve is so constructed that the pressure in the auxiliaiy can be
raised or lowered, depending on the work to be done, by an adjustment
requiring but a few moments.
The ports of the engine are specially designed for the use of air,
and there has been no trouble experienced from the exhaust freezing
up.
The route over which the locomotive travels is shown by the green
line on the accompanying map, and at present the empty cars are
thrown off at the different butt entries in going in, and the loaded
ones taken on when returning. This is made necessary by a scarcity
of mine cars and consumes considerable time. More cars are being
built, however, and when they are put in service, alternate trips will
be made to each entry, which will greatly facilitate the handling of
the output.
