Iwanmi has been ut work on the In
vcntion Ave years. Only recently has
be perfected the OUTFIT however. and
not long ago he had his apparatus pat
ented The inventor has been In Wash
ington several years He Il Of an In
ventiye turn Of mind and has many
other devices that he Is iaboring on
from time to time.
The feature OF Iwanmi's diving suit
II his claim that II viii allow the diver
to 60 to q depth OF 300 feet In the wa
ter. This has been tho weak point Of
other inventions Of this character. ow-
Ing to tho fact that they were not
made to resist the pressure OF the wa
ter below something like $50 feet. An
other feature OF Iwanmis apparatus
Is that by means Of the pumping ma
chinery and the tines OF hose the man
at work Tar below the waters surface
will bc able to remain at his task for
hours ut q time
The air will be supplied by ma
chino which is run By o storage bat
terry. Tho floating paraphernalia will
BE- different from that now In use, In
thnt It will not be boat, but a vertical
doating buoy. This will contain on
assistant or two and the air machinery
leading to the man working 300 feet
below.
After reaching the vessel as It rests
on the bottom Of the sea 1t will be COM
paratively an easy task to bring the
old hull to the surface. Having gained
his point the diver will set about to To-
cate the holes and openings In the
wrecked ship. II the ship went down,
a. did those OF the Russians and the
japanese as well, the holes made by
the shot and shell will be found and
repaired. Then the portfolios, the
hatches and the gangways will be In.
spected and where necessary repaired
TO such an extent that they will be-
come water tight. After this task has
been completed additional apparatus
will be brought into use. and tho work
OF pumping the water from the hull
. will be started.
Holes will be bored In the sides Of
the ship. and into these pipe lines will
be extended. The line will be attach
ed to powerful pumping engines In a
vessel on the waters surface, and SLOW
" but surely the water from the inside
OF the wrecked boat will be brought
out. When this has been accomplish
ed the holes will be plugged, the tenn
porary anchors removed, and, accord
Ing to all calculations Of the inventor,
the steel hull will ascend rapidly to the
top. Here 1t will be attached to a line
and tOwed to the nearest shipyard, to
once again enter the service Of the ma
rine shipping interest of the world.
Iwnnmi has already received an Of
Ter for one OF his diving suits He Is
10 receive $1.5OO for It as soon as
placed aboard ship consigned to tho
parties interested, who are In japan.
The apparatus Is to be made In Balti-
moro. II will be much like other div
ing suits. but will be made stronger by
the use Of steel ribs. These ribs will
be all through the rubber. about half
IN inch apart, and will make It possi-
BILE for the diver to go to much
greater depth and stand the water
pressure than has ever been accom-
plished by means OF tho other inven-
tions. Eventually Iwanmi expects to
turn mis- attention altogether to the
business which win DO brought about
by means OF his invention.
