FANS WILL COOL
CARS IN SUBWAY
Air DiSturberS Will Be Installed
for Benefit of New York
Passengers

NEW YORK, Aug. 22.-"Next
year 40 per cent more heat units
will be discharged in the subway.
Therefore we are now installing elec-
trio fans in the subway cars"
This statement was made by General
Manager Frank r. Hedley of the In
terborough system. He took a party
Of newspaper men Through one of
the cars which has been equipped with
the new fans, and proved to them that
while the temperature was not de-
creased by the operation of the fan,
personal evaporation was aided, and,
therefore, the passengers had the SEN
sation Of GOODNESS, even if they didn't
have the real thing.
Next year we will run ten-car
trains In the subway" said Mr. He'd
ley. "This, Of course, requires more
power. We are now dischargtng 3d.
900 horsepower constantly in the sub
way system, and the number of heat
units under the new plan will be 40
per cent more than at present. We are
going to a great expense in creating
a ventilating plant for the subway,
and are putting in these fans to make
conditions more endurable."
STATIONS FOR VENTILATION
The temperature in the car in which
the experimental fan had been installed
Fahrenheit. He did not state what 1t
would be when 40 per cent more heat
units" would be discharged in the sub
way That the big trench would be-
come uncomfortable under such condi-
tions is suggested by the speed with
which the Interborough authorities are
pushing forward their plans for venti-
lation. In addition to the Ventilattng
stations which are being installed along
the line new fans will increase the
comfort of the passengers.
Each fam" said Mr.. Hedley "is a
four-bladed affair, thirty-six inches in
diameter and revolving seven feet six
inches above the floor. The trains are
400 feet in length inside and each viii
be equipped with four fans, so that
everyone may come within the radius
of their operations. We will equip forty
or fifty cars at once. AS soon as pos
sible we will equip the 1900 cars of
the system at a cost of s120,000 This
will require about 5000 fans. Each fan
Is run by its own motor and has self
oiling device that will need attention
but once a year. They will make 23O
revolutions per minute"
President Shonts, Director Freedman
and other officers of the system in
spected the new fans in operation TO-
day, with the newspaper men. Com

fans were at work and others not yet
equipped showed a balance of comfort
to the credit of the new device.
COMFORT FOR PASSENGERS
James ]. Doyle, the company's elec-
trician, devised them. The first cars
are to be considered merely expert
mental. The equipment will be ex-
tended to the rest of the cars if the
fans prove successful in adding to the
comfort of the subway users. The
ventilating plants along the line Will
be opened at frequent intervals, in
order that more fresh air may be sup
piled to the tube before the dreaded in
crease in heat units comes next sum
mer. At the Brooklyn bridge there
will be a Theoretically sealed water air
cooling plant.
In Chicago a complaint that the pay
as-you-enter cars on the surface lines
are not ventilated properly led the
city's health officer to force the COM
panies to install a new Ventllatlng
system, by which fresh air is admitted
at the bottom and taken out at the
top by fan process. This is not
practicable as yet in the subway, Tor
the fresh air admitted would be or
precisely the same quality and tenn
perature with that expelled at the top.
