Many Changes Reveal
ed in Complete New
Line Of Air-C lied
Automobiles

Climaxing the many triumphs Of
the year in the air by Amerisa's in
srepid airmen, most of which were
made with air-cooled motors, the
Franklin Automobile Company. Of Sy-
racuse, N. Y, One 10 the fore
with the announcement of a COM
plete new line of air-cooled motor
ears christened the Altman Series.
The latest features in the Altman
Series result in increased speed, nil
climbing ae~celeration and decelera-
ton. With this new performance,
il is pointed out that Franklin has
introduced a new kind Of speed, de-
scribed as sustained fast travel at
mile-a-minute and upwards with
a noticeable freedom from vibration.
Franklin engineers state that the
Altman Is able to maintain from SIX
to ten miles faster hourly average
on continuous driving than its pred
ecessor.
In acceleration tests, the Airman
five-passenger Sedan stepped from 5
10 25 miles an hour in a little over
seven seconds, and from 20 to so
miles an hour in IL seconds. Ad-
d%itional power is also pronounced in
hill climbing ability.
The Franklin Company expects TO
produce the three new light weight
seven-passenger cars in the Alrman
Series in large quantities, as this is
the first time in many years when
air-cooled ears have been available
in these types. They employ l2s
iLsh wheelbase, an increase Of nine
inches over the five-passenger chas-
sis. .
All the power plant, chassis and
body changes Of the Altman Series
have been summed up in the new
Franklin slogan, THE most comfort
able mile-a-minute car ever built"
The larger Airman motor has n
cylinder displacement which Is 81 Gu
bic inches greater than formerly, and
operates at three pounds higher COM
preston. Valve ports have been en-
larged and a freer flow Of mixture
10 the combustion chambers has been
brought about by tulip intake valves
and larger ventura tube for the
carburetor. These franklin engine
improvements accomplish an even
greater power increase than the
larger cylinder capacity indicates.
A fully counter-balanced crank
shaft is mentioned By Franklin en-
gineers as the biggest single reason
for smooth running motor and elm
nation of vibration, oar and rumble
that is common in high speed opera
tion. This shaft not only Is inherent
~ balanced, but it also counreracts
the centrifugal effect Of the connect
ing rods. The Airman ~erankshaft
also has double flywheel action
seven bearings and vibration dampen-
ers. Improvements in valve push
rods and rocker arms, as well ss
the use Of double valve springs, are
additional factors in quietness.
The Altman engine is corrosion-
less. A crankcase ventilator drives
off any moisture or gasoline that
might be present in the lubricatinl
oil, thus preventing ore Of the mosi
prevalent causes Of deterioration II
these days Of low grade fuels. A Pur
olator filters the oil rs an added pre-,
caution against wear. Wrist pins ar,
chromium plated to make them i'm.
pervious TO any etching action.
The same type Of oiling system
which has been generally adopted FOL
aviation motors is employed in tn,
airman motor. This is so designet
that proper quantities Of oil cannot
fail 20 reach all motor bearings. By
constant recirculation and filtering
the original filling Of oil serves foi
long mileages and establishes new
economy Of oil consumption FOL
