locity. 1t is these disturbances of the
air the Wright brothers have fought to
master.
The theory of a model flying achine
is to so construct it as to cause the GEN.
ter of pressure to be kept in coincidence
with the center of gravity SO that the
center pressure will not 60 wandering
all over the supporting surface at any
change and angle every time the ma
chine tilts one way or the other. 1t
was the solving of this problem that
will give the Wright brothers a me-
mortal place in the minds of the future
generations.
1t would be, however, worse than
suicide for an experienced person to
venture into the air with the present
mechanical device that governs the
Wrights' aeroplane. Itiequires quick
hand, an eagle eye, and true judgment
to manipulate the levers of the tip
wings and rudders as the wind tits the
machine from right to left, or vice versa.
Only the man with great skill and ex-
perience would venture the control of
the present aerodrOme in mechanical
flight. The ingenuity Of man has yet
to contrive mechanical device or ap-
paratus that would cause automatic
| balance.
For few moments we will consider
the possibility of automatic balance.
By constructing machine that will
keep the center of pressure in c0inci-
dence with the center of gravity the
heliocopter planes are looked forward
to as accomplishing the best possible
result. The machine have in mind
would be Gale "The Automatic Gyro-
scope Heliocopter," consisting of four
heliocopter planes, placed at the four
corners of the compass, forming COM
plete square-each plane revolving in
dept ndentIy of the others. The gyro-
scope or automatic governor, would
take an upright position in the center.
The supporting shaft of the gyroscope
would whirl on a pivot of the motor
shaft-this offering supporting sur
face to the center of pressure in coin
cidence with the center of gravity to
the earth. This principle adopted in
the air, would have the same balancing
effect as adapted to the mOnOrail sys-
tenn. While the whole structure of the
machine may tilt in any direction the
gyroscope whirling On~a pivot-like CEN
ter, keeps perpendicular position to
the earth. Attached to the motor shaft
is the motor pullej ;the motor pulley acts
as central pulley of the four frictions
from which the revolving planes re-
ceive its motor power The frictions
are connected with four respective le-
vers whose haminer heads come to cen-
> ter touching the supporting shaft of the
gyrOSCOpe. 1t can thus be seen at q
glance that when the machine tilts in
any direction it causes an angle at the
Joint or pivot of the motor shaft. If
them achine tilts to the left the pres
sure is brought to bear on the right
, hammer head relaxing the friction con-
!, trOlled by that lever; the right heliocOp-
ter plane connected with this friction
will decrease in speed and drop down
! to level with the other planes and
/ thus balance is restored and the auto
matte governor returns to the center
allowing the right plane to adopt it's
speed again in proportion to the others.
AS the mach ne tilts to right aid left,
. fore and aft, the manipulation of these
automatic levers through the medium
of the governor, all work in a fraction
of second, giving the wind no OPP
pOrtunity to throw the machine off its
3 balance. The heliocopter and um-
| brelIa-shaped gyropter now the object
of experiments, consist of two revolving
or supporting planes only and it has
. been demonstrated that this type of
? machine will not lift more than It's own
weight, besides having only two points
of balance. Natures model, the bird
has four points from which it attains
balance, that is, the head, tail and two
s wings. The same result is obtained by
: the four heliocopter planes have de-
, scribed, working automatically and In
. dependentIy of each other, besides
= doubling its lifting power. All the
t aviator is required to do is to control
f his motor and direct his machine in the
: course he may choose. The perfection
!, of our present motor, to what extent il
: will insure safety in constructing ma
chine of this type, we have yet to con-
}. lecture. 1t will be but short time
f however before our American genius
will overcome ali motor difficulties and
