Wonderful Steam Plant.

VVAASOA AAA SO0OSA1A 4 AOAAOe
The Worlds Fair exposition will
probable have the greatest plant OF
steam and electric power in the world.
To drive the machinery at the expos
ition will require $4,000 horse
power. The power at the Pbiladel-
phia centennial was furnished by the
Corliss engine, now at Pullman, with
a capacity of 1,456 horse power. At
the Paris exposition 5000 horse
power was required. In the machin-
cry hall at the coming exposition the
machines on exhibition will be driven
by six lines of shafting carrying the
required pulleys, each line running
lengthwise with the building, or
about $40 feet. Each of these six
lines will be divided into four Sec
tons of a length of 200 feet, and
each section will be driven by An
engine. These sections of shaftings
will be provided with friction coup.
lings on their ends, so that in
case of accident or the disabling of
an engine its section may be driven
by an engine on the other side of it.
Lengthwise in the machinery hall will
travel three electric cranes of twenty
tons capacity, each having maximum
speed Of 400 feet per minute: Dur
ing the installation of and the rcmov-
al of exhibits these cranes will be
used for transporting goods, but dur
ing the exposition they will be used
to carry passengers through the halls.
At the east end of the machinery hall
will be the exhibit of pumping and
hydraulic machines. These pumps
will supply water for all of the
grand fountains On the grounds and
for other purposes. Here will be a
pumping plant almost equal in cap
acity to the water works of Chicago
There will be pumps working with
a capacity of 4O,O0O,OOO.
In the machinery annex will be
located the electric energy plant
where a number of engines of a
ious types will furnish the 1000
horse power necessary to operate the
generators of electricity for light and
power. These engines will be ar
ranged SO as to form a compact cen.
trail station. This plant is elastic in
its proposed capacity, and this power
can be extended indefinitely. The
estimated necessary 1900 horse
power will probably be increased
rather than diminished. In a build
ing near the annex will be the steam
, plant for furnishing steam power TO
the electric station.
South of machinery hall and op
posite the center of the building vii
be the boiler-house, supplying til
.. steam used in. the building. .Thi
plant will be a model and will hav'
a capacity of 5000 horse powe,
Only in machinery hall will steam
power be used. Electric power viii

e and will be transmitted b. wire

ing the exposition will require a
least $4,000 tons of coal or 225,OO(
barrels of crude petroleum. 1t viii
