VENTILATION FOR STREET CARS
system Devised by Boston Man ir
cheap, Effective and Readily.
Applied.

At the meeting of the American Public
Health association, representing the United
States. Canada, Mexico and Cuba. held In
this city recently, considerable time was
given up to the discussion OF the matter OF
ventilation and sanitation OF trains
The matter OF the Initiated and germ
laden air in trains or the strong drafts
when windows or ventilators are opened to
correct this, was much dwelt upon and the
fact that as yet no good system OF car
ventilation had been hit upon was much
deplored.
Yet while the health experts discussed
this matter. just such a system as they
seemed to desire had already been devised
and proven effective by exhaustive tests.
The plant of the American Public Health
association merely voiced the cry which
has been going up for years and years In
relation to street car and railroad train
ventilation, but the new device referred TO
seems to have effectually settled the dim
Guilty and. problem which for years rail
road men have said could not be sur
mounted.
Practically speaking this new device is
hut the application TO cars OF the cold-air
box principle of the common house furnace.
but when applied to a moving railroad train
or street car. it's effectiveness is way be
yond the widest dreams OF the originator
of that familiar idea.
Louis C.. Lanphear of Boston is the in
/ ventor of the system, which he devised
some years ago and has been perfectinE
since. He has been a travelling salesman
| for over a quarter of a century and has
| put up with as much Of railroad train ven
tilation defects as most ordinary mortals.
| His system is nothing more or less than
small conduit running along either side
/ Of "A.
tors In the monitor opening into this con-
duit. At either end of the conduit are two
openings, the first of these being on the
outside OF the conduit and placed trlne
more than foot from the end
Swiveling from this opening is a Stat or
defector, which allows the air to enter the
opening as the car is in motion and to pass
through the second opening at the extreme
end of the conduit. The lids to these open
ings are controlled by levers operated from
the car vestibule.
When the car is in motion the forward
openings in the conduits are kept closed
and those in the rear end of the conduit are
opened more or less i'm accordance with the
speed at which the car is travelling This
allows the current of air DETECTED by the
swiveling Stat or defector to pass through
the extreme end of the conduit. creating q
suction which draws all the vitiated all
from the interior of the car up aud through
the ventilators opening into the conduit
and this bad air is shot out the end open.

To replace the bad air which he has
drawn off from the car with good fresI
ozone. the Inventor has placed a small ali
register at the end of the car, and this al,
lows flow OF air TO run between the QUITE,
and inner shells of the car structure and
through pipe passing beneath the radia
tors. Directly under each radiator the all
pipe is perforated so that the cold air II

hot radiators and thus become warmed be

That is all there Is to the system. and 4
is the very simplicity of the idea which in
sures it's success. The supply OF fresh ali
entering the car is regulated by valve an,
is under perfect control by the car crew a
all times.
, BY this system, which Mr.. Lanphear hal
invented. the air in the car is kept fresl
and wholesome at all times, and this is &C
complished without drafts. II Is a wei
