ONE-MAN
DIVER IS
LATEST!

LOo ANGELES, Cal, Jan. IL
A submarine SO small 1t could be
tucked in the vest pocket of Uncle
Sam, and which according to its in
ventor, will be leading factor in
ending the European war, was per-
fected recently by Milton ]. Trum-
BILE, of Los Angeles.
Tests made at Alamitos bay near
here with this queer little craft in
dictate that it will revolutionize
warfare on the water, just as the
aeroplane has turned the technique
of land fighting topsy-turvy.
1t will be as great surprise to
the world as was the German SUBJ
sea merchantmen or the British
trench defying tanks"
Here are the most astounding
features of this baby submersibl lie:
IL is manned by one man. He is
captain, navigator, crew and gun
ners
Ii can be transported overland
by motor truck from one body of
water to another; thus being able
indirectly, to attain a speed of 20
miles on dry land, in addition to
making 35 miles on the surface
of water and 20 miles submerged.
Enough of these vessels could
be made in 90 days to protect an
entire nation. They could furnish
an impregnable denfense to small
countries not equipped with fleets
of dreadnaughts.
A whole family of these little
boats could be carried by every
battleship in the American navy.
They could be launched from da-
Wits as readily as are cutters and
launches at present.
The baby divers are fully as ef-
ficient and far less expensive to
operate than are the larger under
sea craft. They are SO quickly
| controlled that it would be i'm
possible for larger vessel to des-
troy them. They can outdistance
the fastest vessels We now have,
and can submerge so rapidly as to
dodge any torpedo fired at them.
Each Sub" carries two torpe-
| does (also the invention of Trum-
ble) weighing 1000 pounds apiece.
They could blow up the biggest
dreadnaught afloat. These tor
pedoes are propelled by special
ly constructed gasoline motor and
are launched from the outside of
the tiny submersible.
The vessel also mounts a light
rifle, such as is being used by un-
der-sea boats in the present con-
flict.
The man and the motor are the
ballast for Trumble's boat. 1t Is
capable of remaining completely
submerged for six hours, and In
case of accident is protected with
an automatic method of rising
which would prevent such TRACE
dies. as the F-4 disaster at Homo
luld
Besides the periscope, 1t is fit
ed with collapsible ventilating
tube which reaches from the boat
to the surface along side of the
periscope. This ventilator can be
used when 1t is desired to conserve
the supply of compressed air.
With one exception the Tumble
submersible is the exact counter
part of the larger divers. 1t lacks
coming tower. All observa-
tons will be made by means of
the periscope. The first model
possessed a coming tower but on
his latest boat the inventor has
dispensed with the hooded cover.
The boats operation in the
water is controlled by two sets of
planes which govern it in SUBJ
merging just as planes control an
aeroplane's flight.
Trumble's vessel is 28 feet long,
and has a depth of 6 feet 8 inches
| and beam of about four feet.
THE ENTIRE SUBMARINE
WEIGHS ONLY FOUR TONS.
All that crew of several men
do aboard the large type of sub
marine is accomplished by one
man in Trumble's boat.
Fifty under-ocean boats of the
type l have built says the in
ventor, could defend each end of
the Panama Canal from an enemy
fleet. They could navigate the
canal even should it be choked
by slides, for they draw draw little
