The Liberty motor, developed by the
department of military aeronautics, is
to have a special engine oil which is TO
be known as the Liberty aero OIL"
It was developed by the fabrication
branch while the latter was still part
of the signal corps. 1t is a mineral
oil and will be used not only on the
Liberty motor but on all stationary
cylinder aircraft engines of the army
and navy.
Its development is due to the energy
and skill of staff of men who worked
exclusively on the problem for a year.
Capt o. J. May, who deserves greatest
credit for its production, so exhausted
himself by his labOrs that he could
not recuperate from an illness and
died
When the aircraft program was an
nounced in 1917 no one in authority
had a definite idea as to the proper
kind of fabrication required. There
was no uniformity. For every engine
there was specific oil. Some en-
gineers insisted ON castor oil, others
mineral oil, still others castor and
mineral oils mixed. 1t was estimated
that 5,0OO,O00 gallons OF castor oil,
costing So per gallon, would be re-
quired and that quantity was not avail
able.
Captain May and assistants set out
to develop suitable lubricant for the
Liberty motor at an average cost OF 70
cents q gallon, and also a system for
reclaiming oil already used. In 25
days Captain May supervised the run
ming of 81 engine tests in laboratory
where five engine tests week would
be complete program. These en-
gines were run with different kinds Of
oils and each oil was analyzed and
measured before and after tests. The
work required ceaseless vigil. Alti-
tude tests were made in an alright
building capable of having the air
within 1t partly exhausted.
From these tests the Liberty aero
oil developed. 1t will cost about one
fourth the price of castor oil, saving
the government perhaps $11 100000
year. system of reclaiming used
oil was developed and at least so per
cent can be made fit to use again.
The national war labor board has de-
cided against establishment at this
time of n minimum wage to be applied
generally throughout industry. II
adopts an attitude firmly opposed both
to unjust profits on the part of capital
and unreasonable demands on the part
of labor. stating that capital should
have only such reasonable returns as
will assure its use for the worlds and
the nations cause, and that the physi-
cal wellbeing of labor and its physical
and mental effectiveness in comfort
reasonable in view of the eXigencles of
the war, likewise should be assured.
The board declares the war 10 be an
interregnum in which the wheels OF
industry should turn only in the com
mon cause and for common ends, and
neither for unjust profits on the part
of capital or unfairly inflated wages
for labor, stressing maximum produc-
ton as the paramount necessity and
unselfish cooperation as the prelimi-
nary essentials to this accomplishment.
There is reaffirmation by the board
of the principle that the worker Is en-
titled to a wage sufficient to sustain
himself and his family in health and
comfort, and restatement by the
board to apply this principle In each
of the cases to come before 1t for de-
cision. !
