quantity production on an American
basis, and ~ was very necessary for
us to develop motor of our own
which would become a standard and
which gould be produced In enor-
nous quantities. As soon as the
United states was drawn into the
war the Packard Motor Car COM
pany offered its models and expert
ence to the government and being
actuated by patriotic motives was
perfectly willing TO abandon, for the
time being, all claim to the origina-
ton of this rHutor. although It had
expended 100000 in it's develop
ment. However, there were soma
changes that the eayernment called
for and 1t was felt that represen-
tative OF some other motor manu-
featuring concern should be called
in to advise with the Packard engi-
neers In the notifications which
would eventually be adopted by the
government Accordingly Major Han
Of the Hnll-scott Motor company
was called to Washington to confer
with Mr.. (now Lieutenant ColoneD
Vincent, chief engineer Of the Pack.
ard company. Mr.. Vincent had with
him the blue prints Of the complete
plans Of his motor and these were
studied by Major Hall, who sug-
Eested a number of changes.
When the war first broke out air
planes were fitted with 100 horse,
power engines. Very soon they
were found to be insufficient and en-
eines of 1875 horsepower were made.
The engine power then gradually in
creased to 15O, l75. 200, $50; and it
was about In that neighborhood
when Major Hall and Mr.. Vincent
were called upon TO furnish tho
United States standard motor, 1t
was felt that a motor should be de,
signed so far ahead In power OF any
thing else that had been produced
that by the time 1t could be turned
out in quantity it would still be well
In the lead. Accordingly Il horse
power of between $50 and 400 was
sought and the size of the cylinders
was changed from 4x6 to 5x7. Be
cause of the larged cylinders re-
duired in the new motor the angle OF
the V was changed from 40 to 45
degrees The larger pistons and
cylinders required slightly greater
clearances. In place OF the forced
fabrication of the crank shaft which
was provided in the Packard engine,
the scupper system was introduced
by Major Hall, because 1t had been
found very efficient on the Hall
Scott motor, This Is also feature
Of the Mercedes motor. The scuppor
consists of small cup-like flange on
the crank arm which catches the oil
and throws II up on the bearing ot
the crank shaft. These and other
slight notifications were thoroughly
discussed and decided upon by the
two motor experts who worked un-
ceasingly and arrived at the finished
design in n conference lasting five
days. They had a herculean task
before them and deserve the highest
praise for the successful outcome OF
their efforts
AS soon as the conference was
over telegraphic instructions were
sent on TO the Packard plant and
work was started Immediately upon
the new motor Even before blue
prints arrived the wood model was
prepared in the general form and
essential features of the new motor
Work on the new engine was pushed
at the highest speed possible, and on
the third day Of July it was COM
pleted and shipped to Washington,
The next day ii arrived there, on
NATIONS birthday and was christen'
the Liberty Motor"
