Do Better
Liberty Motor Output

Could Do

WASHINGTON, Nov 27.-The United
States has produced the fastest air
plane in the world. The output of
Liberty motors for October exceeded
the combined output of both Great
BRIAN and France Of all kinds of air
plane motors for any month. Thus
America, which invented the heavier
than-a air flying machine, regains its
prominence in this regard.
The navy's programme for making
permanent the twenty-onc coastal air
defence stations planned for the war
was explained to the House Appropria-
tions Committee to-day by Rear Ad-
mial Taylor, chief of construction,
who asked that So, 100000 be provided
for this work next year.
Squadrons of fighting aircraft of
every description will be included in
the equipment for stations along the
Atlantic, Pacific and Gulf coasts and
the insular possessions.
New stations, Admiral Taylor said,
are to be erected on the Maine coast,
| between Portland and Rockland; at
Narragansett Bay, New York, Port Ar
thur, Tex; San Francisco, Seward,
Alaska; the Hawaiian Islands, Virgin
islands, Guam and in the Canal Zone.
Stations are now under construction at
Cape Lookout, N. c.; Brunswick, Ga,
been completed at Chatham, Mass;
Rochaway Teach, Cape May, Miami and
Key West, Fla; San Diego, Cal, and
in the Canal Zone.
Fastest Plane in the World
In a general discussion Of plans Ad-
miral Taylor said the fastest airplane
IN the world was built in the United
States This machine, known as the
Kirkham trplane, developed a speed
Of 100 miles an hour, and experiments
better than that The admiral also
told of a German Zeppelin that recent
ly flew from Bulgaria to East Africa
and back. 1t was sent out to bring
home German commander, but he
/ was captured before the craft arrived.
Liberty motor production was at the
rate of $50 day when the armistice
was signed, said Lieutenant H. H. En-
mons, L. S. NJ, chief of the engine
production department of the Aircraft
Production Board, at the War Depart
ment to-day in lecture attended by
Secretary Baker and other army Off
Gals
Deliveries of Liberty motors in Octo-
ber reached 5,297, Lieutenant Emmons
said, a larger number of motors than
English and French factories had been
able to deliver in any one month.
Detailing the history of the Liberty
engine Lieutenant Emmons said only
two changes had been made in design
since its original conception One of
kthese was to substitute "force~fee
System of fabrication for "scupper"
system, and the other was an alteration
IN the connecting rod to give more play.
All other changes. he said. were in
power and were the result of instruc-
tons from experts connected with Gen
cral Pershing's staff.
More Power Needed
The initial engine delivered 800
/ horsepower. After 300 had been manu-
factured and the builders were be-
ginning to swing into quantity pro-
duction, the officer said, the authori-
ties in France advised that more power
was needed. The engine was stepped
up" TO horsepower, necessitating
additional strength in certain parts.
To illustrate the effect of these
orders, Lieutenant Emmons said that
they required changes back to the
steel foundries. which were called upon
to change the specifications Of the raw
steel. Five hundred of the 375- horse
power motors had been produced when
General Pershing asked for another in
crease in power, or for motors de-
! veloping 400 horsepower
Despite these difficulties, statistics
were quoted showing that eleven hun
! dred motors had been delivered on Nav
20, lone year after the first scratch Of
the pencil toward the design of the
engine"
Up to last Friday. the officer said,
the deliveries totalled 31,813.
