vator machinery. The boiler room is foored
with cement, the engine room with stone til
ing and the electric light department with
| hard wood. g
The boiler room is 3S feet wide, Al feet long
with 10 foot ceiling, affording ample light
and ventilation. On the east of tho boiler
room and extending under the sidewalks are
vaults with capacity of 100
tons for the storing of coal. The boilers,
are three In number, of the Baker s. Smith
make, each IS feet in length and 90 inches in
diameter, and have capacity for supplying an
engine Of 200-horse power, third more than
is needed for the heating, elevator and cleo
trio appliances in the entire building Each
boiler is supplied with Kirkwood rocking
and dumping CRATE, a convenience in the
matter of tending furnace and an econo-
mizer of fuel. The boilers are so arranged
that any one or all of them can be used for
any purpose. Connected with them are two
drums, one high pressure for power pur-
poses, and one low pressure for heating, the
drums being connected by finch
sure regulator by which any amount
| of steam from one pound to
boiler pressure may be used for the heating
system. The exhaust pipes from the engine
are connected with the low pressure drum
with back pressure valve which allows the
pressure to escape when the exhaust is
| greater than is required for the heating of
| the building. There are ZOO square feet
of radiation IN the building, supplied from
| this low pressure drum. The steam heating
| is accomplished by the one pipe system, with
| the latest improvements, by which the re-
| turns are carried direct to a receiving tank,
or returned to the tank by system of traps.
| From the receiving tank the water is sent BY
| two Worthington duplex boiler feed pumps,
direct to the boilers or TO the supply
tanks in the pent house in the top of the
building. The heat for the building Is taken
from the low pressIre drum through the
building by forty steam risers all with direct
connections with the source of supply so that
any riser can be shut off without affecting the
supply in the other pipes.
The power for the heating, printing and
electric lighting is furnished by two magnif-
| cent Corliss engines manufactured by the
| Hoffman q Billings company of Milwaukee.
| The smaller engine has a 12x36 inch cylinder
and is rated al s0-horse power. The drive
| wheel is 10 feet in diameter, has a 22 inch
face and weighs 1l,000 pounds. This
| supplies the power for the
presses, stereotyplng apparatus paper Wet
ting machine, plate elevator and day dyna-
mo. The larger engine has 16x4+inch
cylinder, and is rated at $50 horse power.
| The driver is II feet in diameter, has 2S-
inch face, and weighs 1900 pounds. This
monster machine is used only for the opera
lion Of the electric machinery, although the
engines are so arranged that both or either
of them can be used for any of the purposes
required. A hot water supply tank fur
nishes hot water for all of the plumbing fix
lures throughout the building. The exhaust
from this tank is SO piped that it runs direct
or is pumped into COLES patent feed waite r
heater 80 inches in diameter and 10 feet in
leugth, from which it is sent direct to the
| boilers.
The engine fixtures and properties are OF
the most approved patterns. The belts are
endless and rivetess and regulated with the
Eclipse Pulley company's friction clutch
pulley and belt fasteners.
The entire building is lighted by incan'
