The Leuiatl,an Is O. Marpel
Of Neao Electric Appliances

When che Leviathan, the second larg-
est passenger vessel in the world and
the largest under the American flag,
steans into New York next spring from
the Newport News shipyard, she will
represent the latest development in
the use OF electricity as applied to
ocean liners, She will arouse the in
terest Of technical experts as we'll as
casual visitors because of the many
new appliances which are being in
stalled. A few Of the most important
features are outlined by Rear Admiral
Commissioner, In g statement from
Washington. F4 @4t"
II all of the various sizes of cleo
tric wiring were put together end TO
end, thus forming a single conductor
of various diameters, the strand would
reach from New York to Norfolk, q
distance of about 400 miles. The total
weight Of the wire and cable is about
$4,000 pounds. Even this does not
cover all the wire on the vessel, for
there are many more miles OF 1t con-
cealed in the windings of the various
appliances and apparatus. Only about
10 per cent Of the original wiring re-
mains in the vessel.
srnored cables are used and every
precaution has been taken in their
installation Go lessen the fre risk, such
as the provision of special outlet boxes
at fixtures, kick pipes at the decks,
guards to prevent Injury Of conductors,
and the like.
Control and Lighting
For controlling the electric current
in the multitude of circuits 5000
switches Of various types and sizes
are used, the largest being capable OF
handling 5000 amperes and the small
est two amperes.
To light the 1000 rooms on the veg
sci approximately $4,000 lamps arc re-
quired. Many festoons and other fea-
lures are provided for decorating the
ship on special occasions. Some idea
Of the power required to illuminate the
vessel fully may be gained from the
realization that the electric current
consumed in one evening between the
hours Of and II would supply the
ordinary home for seven years.
Artificial ventilation Is obtained in
all parts of the vessel by means of
motor-drlven fans. In order to clarity
the air in some Of the large public
spaces an elaborate ozone generating
plant and system of distribution have
been provided.
In the first and second class accom-
modations electric passenger elevators
serve the five principal passenger
decks. The elevators in the first class
I accommodation are equipped with an
automatic leveling device which al
ways brings the car to stop with the
floor of the car level with the deck,
thus preventing injury to passengers,
Automatic electric provision and bag
gage elevators transport the tons Of
food and baggage from the electrically
cooled refrigeration spaces and bag
gage rooms to the passenger decks.

room electric plate and food warmers
keep the various courses warm until
tne passengers are ready for the next
serving. Automatic push button e1ec-
tric dumb-,waiters carry the cooked
