NEW AIRPLANE
ENGINE ACCEPTED
United States Government Announces
That It Is the Most Perfect En-
CINE Ever Invented.

WASHINGTON, D. c., Sept. IA. i
The Liberty motor, the airplane engine |
upon which the United States is relying |
to establish definite air supremacy over |
the Germans over the battle fields of
France, has passed its final test and is a
complete and gratifying success.
Secretary Baker SAYS: "The United
States aviation engine has passed its
final tests. They were successful and
gratifying. The new motor, designated
by the signal service as the Liberty
motor, is now the main reliance of the
United States in the rapid production in
large numbers of high powered battle
planes for service in the war In pow
err, speed, serviceability and minimum
weight the new engine invites COMPARE
son with the best that the European war
has produced
q regard the invention and rapid
| development of this engine as one of the
really big accomplishments of the Unit
| ed States since it's entry into the war.
| The engine was brought about through
the cooperation. Of more than a score
on engineers who pooled their skill and
trade secrets in the war emergency,
working with the encouragement of the
aircraft production board the war de-
apartment and the bureau of standards.
1.-TWO of the best engineers in the
country, who had never before seen each
other, were brought together at Wash
ington and the problem of producing an
all American engine at the earliest pos.
Isible moment was presented to them
Their first conference. on June 8, lasted
from afternoon until $50 clock in the
morning.
'These two engineers were fgurative-
Ilv locked in a room in a Washington
hotel and charged with the development
of an airplane motor for use by Ameri
lean aviators over the battle fields of
Europe For five days neither man left
the suite of rooms engaged for them
Consulting engineers and craftsmen
from various sections of the country
were brought to Washington to assist
them. The work in the drafting room
; proceeded continuously day and night
Each of the two engineers in immediate
, charge of motor development alternately
worked p hour shift.
"A remarkable American engine wa:
: actually produced three weeks before
: any model could have been brought from
: Europe. 1t was promised that this en-
/ CINE would be developed before tn,
Fourth of July. Twenty eight days aft
er the drawings were started the new
. engine was set up. This was on July 3
"Thirtv days after the assembling o
: the first engine preliminary tests justi
fed the government in formally accept
. ing the engine as the best aircraft en-
CINE produced in any country. The fina
/ tests confirmed our faith in the new mo
0 tor in every degree.
Both the flying and altitude tests o
+ the new motor have been gratifying
T One test was conducted at Pike S Peak
where the United States aviation engin
(; performed satisfactorily at this hig
h altitude. One of the engines, in an ain
Iplane, broke the American altitude rec
