Winnebago have practically demon
strated its utility. / accompanied the
inventor on the last trip and made an
examination Of the boat. Benjamin L. |
Leuzarder and James d. Miller of Mil
waukee, the principal members of the
syndicate owning and controlling the |
craft, were on board also. Mr. Raddatz !
has been experimenting with the vessel |
for eight years. He was completing his |
task three years ago when the financial |
stress overlook America and delayed his |
work. Mr.. Leuzarder and Mr.. Miller
became interested in the plan about two
years ago and have supplied the neces-
sary funds.
The submarine boat looks as though
it would be equal to any reasonable de-
mands that might be made upon it.
Everything about it indicates that it is
essentially a man of war, its steel PROV
being capable, it is asserted, Of piercing
the sides of any cruiser afioat. From the
outside the boat looks like huge cigar.
1t is 65 feet long, A feet wide and z p
feet in depth. It's weight is 81 tons. 1t
is built of steel plates, closely fitted over
heavy framework of iron, and the in
ventor estimates that it can withstand
the pressure of the water to depth of
500 feet
l entered through the turret, which
is two feet high and furnishes the only
entrance or exit
The closing of the manhole of the
turret and the descent into the water
causes novel sensations at first, yet
trip lasting more than an hour, with a
submersion varying from 10 to 20 feet,
furnished no unpleasant experiences.
| The air in the boat at the end of this
| period was as pure as at first. Mr.. Rad
datz keeps his process of furnishing air
a profound secret
The boat inside is four feet in diam
eter at its widest point, making 1T I'M
| possible for man to stand upright save
| in the turret. Here are fitted several
bullseyes with strong lenses for explora-
| ton. There are two sets of machinery
for propelling purposes, hot air engine
of nearly 30 horsepower for use on the
surface and an electric motor for the
submarine voyages. Immediately under
the turret is steering wheel, like the
wheel of small yacht Mr.. Raddatz,
in operating the boat, sits under and
slightly to the rear of the front turret,
holding the steering wheel with his
right hand, while with his left hand ht
controls the starting button on the left
O small knob that starts the motor. Two

pearge are on the right hand, and al
automatic machine has been provided t.
prevent the submersion of the boat be
yond the depth desired.
There are several batteries, and if on
breaks down others can be quickl.
put in to take their places. The batter.
cells are in the side Of the boat, ant
connected with them is one of the mos
ingenious devices of the inventor. Whe'
the cells become exhausted, the moto
used for propelling under water is re
versed and run as dynamo, and the.
are recharged. In the stern of the boa
is hot air engine, like the pumping
engines used in factories, connecte'
with the propeller shaft. A storage bat
terry of 80 cells is also near the engine
All the valve gears are inside the tur
ret, within easy reach Of the pilot, an
all the machinery that operates thi
craft is easily managed by one man
, the boat obeying him with the utmos
, readiness. The turret is only two fee
in diameter, and holds only one perso
at o time. The boat accommodates onl
, | about four persons comfortably, n
though six might be slowed away j
her.
The motion of the boat in the waite
is so even that it is almost impercept

aboard at the rate Of Ia miles an hou
n and submerged at ten miles, althoul

The lighting of the boat is electr
and is satisfactory. A wire loop on Il
