HERES EVERYTHING ABOUT
OUR NEW LIBERTY MOIOR

(, the plane on top in war work, and for
that reason it is essential that the
Liberty climb as high and as QUICKLY
as any other, but she still has ma

Give These Men Credit.
II is conceded by investigators that
Major Hall of the Hall-Scott company
iC. Harold Wills of the Ford Motor
company, Mr.. Charles kettering oi
| the Dayton Electric company. u. NC
Call White of the Cadillac company
and Colonel Vincent formerly or the
! Packard company, should nave the
credit for the design of the L1Derly
motor, and that to the Ford Mo'or
company and its organization OF netai.
jlurgists and engineers goes the creole
! for making the cylinder out OF piece
or tubing instead of out of solid steel
! forging which would have weighed
! 100 mounds in the rough and about six
hounds when machined.
New Cylinders Important.
| The cylinder made from the tube
L has a greater safety factor because
there are not the same dangers OF
flaws and fractures in the metal due
to the forging process. Without the
Ford cylinder it would be practically
impossible to manufacture the Liberty
motor in any quantities, entirely aside
from the fact that it is a better cy-
Under and has a better factor OF SAFE
ty.
The ignition system, which we are
Informed is nearly 100 pounds lighter
than would have been necessary D!
the use of magnetos, is result OF the
brain of Mr.. Charles Kettering, con-
coded by automobile men to be one
of the greatest electricians living. !.
When the statement is made that
week before last forty-two of these
fighting machines complete were
shipped from one airplane factory
alone. it must be considered that with
each machine goes rs per cent.
"spares," to that when you ship 1our
machines you really ship seven.
About Those Radiators.
| There has been a great hue and cry
about the failure of the Liberty engine
to cool. An engine is supposed 10 se'
hot and the fact that some of these
engines boil On the ground wnen III
fifteen minutes they will be in tenn
perature about zero Or little below
| did not strike these critics as havlns
anv bearing whatever on the amoun'
| of radiation surface which the motor
| should have. 1t is merely question
/ of whether you want the radiator
large enough to cool the engine with q
wide open trottle On the first lo,eo'
feet Or whether you want the radiator
so proportional that it will keep the
engine warmed properly up In tine
"tusiness district" Nobody cares
about the temperature at the"port o.
entry down here. 1t is up there where
YOU are doing the work that it shoulc
| remain at tie most efficient temper
allure.
Most of the stories we read ABOUT
the Liberty motor not being able to
get off the ground, ETC., come from In
eyperienced observers who hang ABOUT
the fields where the manufacturers
are trying out various makes OF pro
pellers. etc, and when they see
plane upon which is being tried some
new type Of propeller and they see il
doesn't rise from the ground they rush
away to write that the Liberty plane
is failure When they see an engine
boiling which has been run at open
throttel on the ground for this very
purpose they Immediately conclude
that the Liberty engine will not cool
