GREAT PROMISE
IN new MOTOR
Turbine Expected to Rev.
OIuti0nize Marine
transportation.

By his discovery of the national re-
versible turbine motor Thomas East
moore, an inventor Of Jacksonville,
Fla, proposes to supply a motive pow
er on water that will revolutionize ex-
listing transportation facilities says the
New York World. By actual test OF a
small boat built after an .Eastmoore
model the inventor has developed
speed OF fifty miles an hour on the ST.
Johns river, Florida. When new models
are completed he expects to show
maximum speed OF seventy-fve miles
an hour under favorable conditions. In
brief, II the EastmOOre turbine motor
with reversible gear comes anywhere
near fulfilling the hopes of the inventor
transatlantic greyhounds will cross the
ocean in three days and with e-half
of the present fuel supply.
Like all inventors, Mr.. Eastmoore
has met with many discouragements.
Last winter his boathouse on the ST.
Johns river was destroyed by fire, and
all the models, boats and motors We're
consumed, and the inventor and his
family barely escaped with their lives.
Now he IS at work upon new models.
and a new boat will be constructed in
time for a trial demonstrative of high
speed off Palm Beach, Fla, during the
motor races next January.
BY his invention Mr.. Eastmoore
claims that he can save one-half of the
present cost of fuel. one-half to three
IN
and double the horsepower with a Civ
Ell head of steam. He claims an ability
to do away with all vibration, TO gain
10 per cent IN friction and to save from
one-half to three-fifths in the present
cost of manufacture. And, TO crown II
all, he declares that he can reach and
maintain a speed OF fifty miles or more
an hour
The turbine engine patents granted
to Eastmoore cover three different
types of reversible compound steam or
gasoline engines. There are three prin-
ciples on which they can be construct
ed-frst, the screw principle; second,
the old over and undershOt water
wheel principle. and, third. the spiral
or windmill principle. All three of
these are comprised In the Eastmoorc
inventions, and gasoline is the fuel
used.
A seventy-five foot launch has been
designed by him to be equipped with
twin screws driven by two 100 horse
power reversible engines. The launch
will also be equipped with the East
moore propeller under the bow, new
departure in engineering, as well as an
ordinary propeller at the stern, and a
speed of over fifty miles an hour by
this craft is expected by the designer.
The speed of the motors will be regu-
lated at 1000 revolutions a minute.
From practical experience Ii has been
found that two and three bladed stern
propellers work better with higher
speed attained than u four bladed pro-
peller shows, for the reason that the
four bladed propeller creates more
vacuum than the two and three blad
ed propeller The bow propeller used
in the Eastmoore boat works in a solid
body of water constantly.
The turbine engine Is without center
and takes the steam on the run. When
the diameter is doubled the same head
of steam will be doubly effective To
explain: II the piston twelve inches In
diameter develops thirty horsepower
with u two inch steam feed, the twenty
four inch piston will, with the same
two inch feed, develop sixty horse
power.
Eastmoore intends to develop 10000
horsepower from 800 to 1000 reyolu-
tons per minute.
