all for soft coal or wood burners. For anthracite coal the form of the
furnace is changed, giving a longer grate and shallower fire-box. The
barrel of boiler, length of connecting-rods, number and length of
flues, etc., remain the same, so that no change in principal patterns
results. The change in shape and dimensions of fire-box, however,
alters the distribution of weight, throwing more load on the drivers
and less on the truck, while the total weight of engine remains nearly
the same. The hard coal burners, accordingly, having from this cause
somewhat more adhesion than the soft coal burners of the same class,
have proportionately more tractive power, and will haul loads from ten
to fifteen per cent. greater than those given for the corresponding
soft coal or wood burning engines.
STRAIGHT AND WAGON-TOP BOILERS.
All the engines of this division are built with wagon-top boilers or
with straight boilers and two domes, as preferred. Where the latter
form is made, the throttle-valve is placed in the forward dome. The
wagon-top and straight boilers for the same class are so proportioned
as to give equal steam space and the same number of flues in both
forms of construction.

HARD AND SOFT COAL BURNERS
In the three classes of engines of Division II. certain differences
occur between hard and soft coal burners. The print on page 68
illustrates the plan of the soft coal or wood burner. In the hard coal
burner the fire-box is made longer and shallower; the rear drivers are
brought farther forward, and the three pairs of drivers are arranged
so that the distance between centres of rear and main drivers is the
same as the distance between centres of main and front drivers. The
point of suspension of the back part of the engine being thus brought
forward, a greater proportion of the total weight is carried on the
drivers and rendered available for adhesion, and the tractive power of
the hard coal burner is accordingly somewhat greater than that of the
soft coal engine. The rigid wheel-base of the hard coal burner is also
lessened from 17 to 24 inches by the same modification.
CURVING.
All engines of this Division are built with a swing-bolster truck. The
middle pair of drivers have tires without flanges. The engine is
accordingly guided on the rails by the truck and the flanges of the
front driving-wheels, and is found to pass curves without difficulty.
If preferred, however, the front instead of the main pair of drivers
can have the plain tires. Both methods are in use.
STRAIGHT AND WAGON-TOP BOILERS.
All the engines of this Division are built with wagon-top boilers or
with straight boilers and two domes, as preferred. Where the latter
form is made, the throttle-valve is placed in the forward dome. The
wagon-top and straight boilers for the same class are so proportioned
as to give equal steam space and the same number of flues in both
forms of construction.

ADDENDA.
ANTHRACITE COAL BURNERS.
For anthracite coal, a long and shallow fire-box is constructed, and
the back driving-wheels are placed at the same distance from the main
pair as the latter are from the front drivers. This reduces the rigid
wheel-base to some extent, but retains the same weight on drivers.
CURVING.
The leading wheels having a swing bolster, and the middle pair of
drivers having no flanges, the engine is guided by the truck and the
front drivers, and is found to pass short curves without difficulty.
TRACTIVE POWER.
It will be seen that in engines of this pattern nearly all the weight
of the machine is utilized for adhesion, only enough load being thrown
on the leading wheels to steady the engine on the track. The tractive
power of these engines is accordingly greater in comparison with their
total weight than that of either the eight-wheeled C or the
ten-wheeled D patterns, and they are, therefore, especially suited to
working steep grades and hauling heavy loads at low speeds.
STRAIGHT AND WAGON-TOP BOILERS.
All the engines of this Division are built with wagon-top boilers or
with straight boilers and two domes, as preferred. Where the latter
form is made, the throttle-valve is placed in the forward dome. The
wagon-top and straight boilers for the same class are so proportioned
as to give equal steam space and the same number of flues in both
forms of construction.

ADDENDA.
GENERAL DESIGN.
The plan of this engine admits of either straight or wagon-top boiler,
and of the use, with the proper form of grate, of either anthracite or
bituminous coal or of wood.
WHEEL-BASE.
The arrangement of the wheels is such as to permit the engine to
traverse curves with nearly as much facility as an engine of the
ordinary type with only four drivers. The leading wheels having a
swing bolster, and the front and main drivers having no flanges, the
engine is guided on the rails by the leading wheels and by the flanges
of the rear and second pairs of drivers. It is, therefore, impossible
for the wheels to bind on the rails. Engines of this class are run
around curves of 400 feet radius and less.
TRACTIVE POWER.
The distribution of the total weight of the engine gives about
twenty-two thousand pounds for each pair of drivers,--a weight no
greater than is carried on each pair of drivers of the larger sizes of
ordinary eight-wheeled C engines. The single pair of leading wheels
carries only nine thousand pounds. This arrangement renders available
for adhesion a total weight of 87,000 pounds. One of these engines on
a recent trial hauled one hundred and fifty gross tons of cars and
load up a grade of one hundred and forty-five feet with sharp curves,
and two hundred and sixty-eight gross tons of cars and load up a grade
of one hundred and sixteen feet to the mile. The pressure in the first
case was one hundred and ten pounds, and the speed six minutes to the
mile; in the second case, the pressure was one hundred and twenty
pounds, and the speed seven and one-half minutes to the mile.
These engines are especially adapted to the working of steep gradients
or where heavy loads are to be moved.
