Has Been Successfully Testec and Is
Ready TO lie Tried at Havre.
NJ. Piaau delPozzo is now carrying on
a very interesting series OF experiments
al Choisey Ie Roy, which mark an i'm
portant step toward tho solution Of the
problem Of working al great depths under
the sea.
Like all OF tho recent submarine work
ers. the inventor acknowledges that his
object is 10 recover lost submarine treas
ure. lie gives the credit OF his machine
20 jules Verne, who first conceived the
iuea OF submarine craft; but he also an
nounces that Il great deal is due his own
ingenuity for the very clever way in
@hich he has adapted the primitive idea
TO his present boat
The name Of the machine is the Sub
Marine Worker" and the inventor claims
for il that. while diver can only de-
scend 10 a depth of 10 feet, and the
diving bell 10 80 his apparatus will en-
able men TO work al depth Of from JOJ
to 200 feet below the surface Of the sea
The submarine worker consists OF
large hollow globe OF east iron. on the
top of which is a small railing. Inside
the railing is n door through which men
can descend into the interior Of the globe.
X
the globe is ten feet across. after descent
into the interior, drop door seals itself
automatically. 10 is then secured by nuts
and screws so that the globe is POSI-
lively Water-tight.
The men descend tho latter and ind
themselves I'm a room completely fitted
out with every facility for deep sea work.
There are windows that give view Of
the surroundings. and there are many
graphing hooks for the securing OF treas
ure. The room is large enough TO contain,
I'm addition to the men, electric accumu-
latOrs. connecting rods TO the screws. 50
that they can be used at any time. and
the mechanism controlling the rudder by
means of which the boat Is steered. and
telephone apparatus for communication
with the surface above.
The room IS lighted by electricity. Out
side the largest window there hangs a
powerful light. which IS suspended, ike
the globe itself from the surface above
one OF the simplest though most effec-
tive features, Is a large graphing hook,
which is fastened to the end Of an au-
tomato rod, which IS worked from the in
side Of the globe. A cable dropped from
above also connects with this hook. The
men working inside are 10 fasten the hook
by means Of the interior rod into any
treasure that may be found, when the
men above pull it up to the surface by
means Of the cable.
BY means of three screws and the
ladder the machine can be steered about
at pleasure. 1t can move around a wreck,
or can revolve on its own axis. IL can
turn around a reef of rocks, and while
revolving, the graphing hooks can be
worked from the inside and pieces Of
wreckage brought up to the boat above.
The submarine worker requires a vessel
as an aid upon the surface. This vessel
lowers the globe and holds itself in read
mess to pull up the pieces of wreckage.
II also takes charge Of the telephone wire
which runs along the cable by which
the machine is lowered TO the depths OF
the sea.
This cable is a very firm one, but in
case IL should break. the boxes OF bal
last which are fastened TO the bottom OF
the globe, can be severed from II, and
the globe will then rise Of itself.
This Is the safest submarine worker
ever invented. 1t involves almost no
risk Of life. There are no automatic doors
that open and close as the diver goes out
into the water and comes back, conse-
ouently there IS no chance for the bell
to fiji with water IL IS sealed before being
lowered. and the supply Of air is suiiic-
lent to last the men until they are raised
again. When they feel that they need air,
they can give the signal, when the AIR
can be renewed.
The weight OF the machine is such
that It is almost impossible TO handle
II on land. 1t floats in the water, and.
being hollow IL hobs Ike a ball upon
the surface Of the ocean. Its weight is
ten tons. but owing 10 the nature OF its
construction il will not sink without the
boxes OF ballast
One Of the most important things is the
large wooden rudder which steers the
globe in any direction. IL IS necessary
i'm the progress under the sea 10 keep
in communication with the vessel above.
The man at the telephone in the globe
at the bottom Of the sea tells the man In
the ship above In what direction 10 move,
and at the same time he turns the rudder
10 guide the globe. In this way an exact
course can be taken, and stops can be
made wherever desired.
The first experiment was a complete
success, although II was not attempted
at any great depth, the inventor claiming
that the machine was not quite ready
FOR deep sea work. In few days, how
ever, IL will be sunk in the deep sea OF
Havre. where II will be put TO work at
depth OF 400 feet Should it prove entirely
successful the syndicate backing the in
yentor will at once start out upon the
manufacture OF its structure, and new
impetus will DO given to the ever fasci-
mating work OF recovering lost treasure
from the seas bed.
This apparatus is the most simple OF
any vet invented, and, II the globe IS
strong enough 10 resist the force OF water
there is no reason why IL should not work
