NEW TURBINE MOTOR
discovery That May Revolu-
tionize Marine Transportation.

rrventor Says Steamships Equipped
With His Engine May Cross the
ocean In Three Days With One
s. half of Present Fuel Supply-TriaIs
off Palm Beach.
n Bv his discovery of the national re-
vprsible turbine motor Thomas East
moore, an inventor of Jacksonville,
Fla. proposes to supply a motive pow
3 pr on water that will revolutioniZe eX-
sting transportation facilities, says the
New York World. BY actual test Of a
small boat built after an EastmOore
model the inventor has developed a
speed of fifty miles an hour on the st.
Johns river, Florida. When new models
are completed he expects to show a
maximum speed of seventy-fve miles
Ian hour under favorable conditions. In
brief. if 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 One-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 were
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
ffths in space, make fewer revolutions
and double the horsepower with Civ
en- 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 1t
all, he declares that he can reach and
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
d-frst, the screw principle; second,
the old over and undershOt water
wheel principle, and, third, the spiral
Or windmill principle. All three OF
.hese are comprised in the Eastmoore |
INVENTIONS, and gasoline is the fuel
used.
Seventy-tive foot launch has been
designed by him to be equipped with
win screws driven by two 100 horse
)ower reversible engines. The launch
VIII also be equipped with the East
moore propeller under the bow, a new
departure in engineering, as well as an
ordinary propeller at the stern, and
peed of over fifty miles an hour by |
his craft is expected by the designer.
Inc speed of the motors will be Fegu-
ated ut 1000 revolutions a minute.
From practical experience it has been |
ound that two and three bladed, stern |
@ropelers work better with higher
peed attained than a four bladed pro-
,eIer shows, for the reason that the
our bladed propeller creates more
acuum than the two and three blad-
u propeller The bow propeller USED
the Eastmoore boat works ia a SOLID |
ody Of water constantly.
The turbine engine is without center
10 takes the steam on the run. When
le diameter is doubled the same head
Steam will be doubly effective. 10
Aplain: If the piston twelve inches IN
Lameter develops thirty horsepower
18th a two inch steam feed, the twenty
our inch piston will, with the same
"o inch feed, develop sixty horse
over.
Eastmosre intends to develop 6O,O0O
orsepower from 1900 to 1000 revolu-
ons per minute.
