plainly apparent. Under the present
circumstances it is necessary for the
diver to sink directly to the bottom be-
fore he can begin operations. With
the new contrivance he can pedal about
at any desired distance above the bot
tom and take a bird's-eye view, as it
were, of the scene Of operation. Thus
1T will be seen that the submarine BIZ
cycle, from business standpoint, is a
very excellent thing indeed
Entirely unlike anything ever before
produced in the bicycle line, this
machine is still in all it's essential
features a bicycle, with wheels, gear
ing, Sprocket wheels and all complete.
1t is intended solely for submarine use.
1t is painted with a waterproof COM
position which prevents rust
The machine itself consists of the
regulation shaped bicycle frame, two
wheels, the usual running gear, with
some additions, and two cylinders.
These cylinders are really the secret
OF the whole machine, and it's ability
to travel below the ocean. They are
about eight feet long and nine inches
IN diameter through the center, Their
construction is a bit peculiar in that
Whlle they are constructed of copper.
they are balanced with several hun
dreds of pounds of lead fastened TO
the under side. This is done so that
when beneath the surface. the cylinders
Will maintain their proper position
The cylinders are filed with air and
serve to keep the submarine bicycle at
the desired depth
1t is by means of these same cylin-
GERS that the machine is raised or
lowered at the will of the rider. On
the forward side of each cylinder is an
automatic valve which is controlled by
the rider by means Of a wire running
from the valve to the handle-bar of the
machine This valve opens into two
narrow compartments running the
length of the cylinder and is kept
closed by the outside pressure of the
water.
When 1t is desired to send the ma
chlne to any depth the rider pulls the
wire connecting with the valve and the
1nrashlng water causes the machine to
gradually sink below the surface.
When the desired depth has been
reached the wire is released, the valve
closes and the machine remains sta

but between the surface and the bot
tom Of the ocean.
Connecting the two cylinders are two
hollow metal rods which serve the
double purpose Of connecting the air.
hlied cylinders and acting as axes, for
the two wheels Of the bicycle. The
rims of the wheels project above and
below the cylinders. These wheels
have the customary spokes, inter
woven as usual, but the run is entirely
different from that of the land ma
chine.
In place Of the big pneumatic tire
the outside Of the rims of these wheels
are fitted with cogs These cogs fit
into the cogs of two much smaller
wheels, which work on q rod running
along close beside the wheels on the
opposite side from the running gear.
These cogwheels are cone-shaped and
firmly fixed to the rod, at the rear end
of which is a propeller
The pedals of the submarine bicycle
are fixed in exactly the same manner
as on an ordinary machine, the only
unusual appearance being that instead
of one chain there are two, one con-
