The star. (Reynoldsville, Pa.) 1892-1946, 1897-07-21

either the Sims-Edison or the White
head torpedo can be used. With air
supply enough to last crew of ten
men for twelve hours the yacht can APP
proach the enemy unseen from q very
great distance There would be alb
solutely no warming, no hint Of danger
to those on board the ship she picked
out for attack. While sailing along
without q sail or truce of smoke in
sight to indicate the presence of an
enemy, the most powerful battle-ship
might suddenly be heaved into the air
and her bottom literally torn out of her
by fearful explosion.
Those on board who escaped instant
death would never know what had be-
fallen them, whether their own boilers
or their own magazine had blown up,
unless the submarine yacht rose to the
surface and fshed them out of the
water and the wild chaos of tossing
wreckage which in few moments would
be all that would be left of their ship. III
the vessel attacked were of fleet
her fate would be as much a mystery
to those on board her sister ships as TO
her own crew. There would be dull,
smothered explosion, lifting of the
huge mass of metal heavily upward,
then staggering, headlong lunge into
the depths of the sea and the tossing
arms of those not dragged underneath
by the suction ms the ponderous mass
sunk out of sight.
On board the submarine yacht the
spectacle would be even more thrilling
than from the decks of vessels on the
surface of the water. After hurting
its torpedo low down against the ex.
posed flank of the enemy there would
be reversal and swift whirling of the
twin screws until the vicious little
craft had darted back to safe dis
tance from the concussion and the
wreck the deadly explosive had wrought.
Then she could creep quietly back, and
her officers and crew, with their elec.
trio search lights turned on the scene
and the steel panels slid back from be-
fore her broad plate-glass window,
could watch at their leisure every de-
tail of the death agonies of sinking
But aside from oil mere anticipatory
speculations as to what it may accom-
plish in actual warfare, Mr.. Dantz-
becher's submarine yacht is fast as
suming the proportions of a practical
business investment. Its details have
all been carefully worked out and the
plans drawn. The boat will be 100
feet long over all and twelve feet in
diameter at the midship section.
1t is cigar-shaped cylinder in form,
for the reason that the cylinder will
best resist the pressure of the water,
which at depth of ninety feet is thirty
nine pounds to the square inch. When
submerged there will be displace-
ment of 169 tons. The plating in the
middle fifty feet of length is half inch
of mild steel, with thickness of three
eights of an inch at the ends.
"The diving apparatus of the boat, '
said Mr.. Dantzbecher in recent in
terview, sis radically different from
anything yet constructed, and is cop
led from the fish. There is shaft ex
tending athwartships and going two
feet beyond the hull, to which are at
tached the diving planes, which or.
horizontal rudders, placed one on eacl
side and two feet wide by ten feet long
located about twenty feet from the
bow. There is also duplicate set o.
these planes about the same distance
from the stern, and so designed tha
they may be worked Independently ol
togethers A fish balances in thu
water, and rises, falls or maintains hi,
level by the use Of the two fins placed
just back of his gills. This is fact
of which any one may convince himself
by watching goldfish in an aquarium
'"These diving planes, placed fore
and aft, will in the same way contro
the depth of the hull in the water, {
set of levers in connection with cylin
ders either elevating or depressing
them for rising or falling in the water
and 80 arranged that the pressure O
water outside Of the hull makes it au
tomato in operation and keeps thu
boat on an even keel at all times at an,
desired depth.
There will always be maintained
reserve buoyancy OF from 700 TO 100l
pounds, 80 that should the machiner,
In any way become disarranged th'
| hull will at once come to the surface.
