The commercial. (Union City, Tenn.) 190?-193?, 1915-06-18

strated with an alternating current OF
%, 900 electric volts, three times as much
as is used in the electric chair. This
generated with the aid OF other patents
the rays which were stored on disk,
first three simple colors. In this demon
stration the tent lights were turned out.
On the disk the rays could be seen and
these lights we're stored on the disk and
will remain there for hours. But when
the lights are turned on nothing at all
appears on the disk. By this method
f; Mr.. Wood says rooms can be stored
with light that will remain all night
without the aid OF electricity. The disk
was used after the first demonstration
to illustrate a combination OF colors,
some moving in one direction and 9TH
others in transverse directions. By this
means artificial flowers we're stored with
light and the word Light" was written
by Mr.. Wood on board with the violet
ray, all these we're perfectly visible and
plain all over the tent. The storing OF
the ultra violet ray, Mr.. Wood says,
will sometime be used to take the place
OF the present lighting system.
The second demonstration was with
the gyroscope, which Mr. Wood has
patented from the principle of gravi-
tation and its counter forces. The first
was a revolving machine turning in a
perpendicular position with swinging
chains. This was put in motion and the
centrifugal force caused the chains to rise
to the level Of the wheel and remain SO
while in motion. The next was heavier
wheel, something like bicycle wheel
with balls on each end of the axis. This
was put in motion and one OF the balls
attached to vertical stand. The wheel
OF its own momentum swung around
the standTin a vertical position. An
other attachment was used to cause the
wheel to swing upward and then the
wheel turned in perpendicular posi-
ton. The next was small gyroscope,
a shell containing wheel of the same
type as shown. This wheel is put In
motion and when it is making thou
sands of revolutions the gyroscope will
stand in a vertical position and cannot
be changed from this position except
with powerful force. A bi-plane was
shown and the gyroscope placed on the
by-plane and sent on wire across the
tent. The bi-plane was held in its posi-
ton, dropping neither to one side nor
the other, but when the gyroscope was
removed the bi-plane dropped under
the wire.
Then big gyroscope was shown and
some gentlemen from the audience on
the stage were invited to make, some
tests. The wheel was started until it
was making three thousand revolutions
minute and the visitors we're invited
to take pole and force it down to the
floor in perpendicular position. This
was the cause OF considerable amuse-
ment to the audience. The gyroscope
could not be turned from its vertical
position. Mr.. Wood said that the gyro-
scope could be used in the manufacture
of automobiles so that the cars would
move vertically on single wheel, and
he tried to get some of our makers to
test it, but failed, and the French took
it up and were making mono-truck cars
but when the war began could not ship
any to America. This will be the auto
mobile OF the future, Mr.. Wood says.
He then took the smaller gyroscope and
made the test OF the mono-rail car,
which was sent across the tent on
wire, held in position with the gyro-
scope. As soon as the gyroscope was
removed the car turned turtle under the
wire. Mr.. Wood was assisted in these
demonstrations by his daughter and the
crowd was delighted with them.
