square inch. II you multiply the 7000,-
| 600 square inches by this pressure ana
divide by 2,2i0 - representing the
pounds Of a long ton-you will find
that the superposed sea has laid its
hand upon the body OF the Titanic
with weight OF more than 14,O00,OO0
tons.
When afioat and fully laden the
great liner represented a dead weight
OF $1,000 tons. II she be held in the
grip Of the ocean bed with the sea
further aiding that hold, the salver
would have TO exert a lifting force OF
more than 215 times her service ton
mage In order TO free her from the bot
tom. In other words, Mr.. Smith would
have to provide salvage caissons or
camels with an amassed buoyancy
equivalent to an assembled feet OF
floating Titanics more than 2l5
strong! From a financial and engineer
ing point of view an undertaking Of
this sort would not be alluring.
But it may be that the wreck of the
ship is not in this unpromising pre-
dicament. How is the Denver inventor
to satisfy himself upon this point?
Mr.. Smith has planned as an auXil-
iary type Of submarine boat which IS
TO be strong enough TO withstand the
deepest submergence required for the
reaching Of the Titanic wreck. In this
direction the inventor is practically
celebrating on the work Of the noted
Italian submarine engineer Signor
Pine.
The latter designed a type Of globu-
lar submarine, which, because OF its
particular form and the nature OF It's
fabrication, would stand up under the
stresses Of very deep sub
In fact, the boat-if such |
it could strictly be called-was so ar
ranged that increasing pressure actu- /
ally served to make the craft more .
watertight.
According to Mr. Smiths plan,
these submarine auXilaries will be /
lowered from big wreckiHg steamers
and will obtain their limited propulsive
energy from the electric power plant
Of the surface craft. Their purpose
will be two fold: That of locating and
exploring externally the shattered
wreck, and to assist in guiding and in
pushing the powerful magnets into
contact with the steel hull. It would
be Of the utmost Importance to place
these mechanical leeches where the
internal structure of the Titanic would
be best able to support the lifting
strains
Lifting magnets are extensively em-I
Dloyed nowadays in big steel plants,
and lately have been used also for
he recovery or iron and steel scrap
which has been lost overheard in har-
,ors. A we'll known English firm has
,uilt some Of these with a diameter of
i've feet and with magnetic grip
trong enough to raise a solid mass
# iron or steel Weighing y tons.
One of the main difficulties in the
ise of magnets is to avoid overheating
hem by reason of the electrical cur {
ent turned into them. This element
f temperature has hitherto placed
limits upon their attractive powers, |
nd especially upon prolonged continu-
us service, something that would be 8
bsolutely needful in dealing with such S
project as the lifting Of the Titanic {
nd holding her during the towing into {
hailOwer water. However, news has !
ONE from Paris of late announcing an T
Important discovery in this matter of 7
lcraasing the strength Of magnets /
ithOut adding materially to their I
ze.
Unquestionably the temperature of 4
le sea water where the Titanic now f
es is very close to the freezing point, a
nd 1t may be that the Denver engi- f
eer counts upon this condition to pro a
lote the efficiency of his magnets t.
hen first gripping the wreck and d
.arting it surfaceward. AS the matter c
ands, however, the present state of
le art calls for magnet weighing
Jout sixty-eight hundredweight to
It burden Of 12 tons. II the Titanic v
,oke just forward of the bridge, and n
the after section represents two D
Iirds of her total weight, then the h
ad to be lifted would be equivalent
