The balancing device in the Wright
machine is secured by an ingenious
scheme for manipulating the two main
planes. These planes are so arranged
that they can be warped endways. Run
ming along in the muslin that covers
the planes is a stout wire which eX-
tends from the operators seat in front
TO the far ends of the lower plane. By
moving a lever one end of the lower
plane can be pulled down and the other
end, by the same movement, pulled up.
AS the planes are hinged together, one
operation of the lever has the same ef-
feet on both of them.
If for any reason, then, such a cross
wind, inequality Of air currents, or
perhaps a miscalculation in the dis
tributiOn Of weight, the machine begins
to tilt sideways, the operator, by the
use Of his lever, lowers the rear corners
of the two big planes on the side of the
machine that is sinking. and raises the
Corresponding corners on the other side.
BY this movement q greater surface on
the sinking side of the machine is ex-
posed to the rush of air that is coming
in from in front, and that side of the
flyer instantly ascends.
Method Claimed to Be infringement.
Glenn H. Curtiss, who made such a
brilliant record in the flights at Rheims
last month, balances his flyer by means
of two small auxiliary planes placed
horizontally half way between the ends
of his main planes. By moving these
plaTes so that the one on the sinking
side of his machine is turned directly
against the wind, ne secures a greater
plane surface on that side of the ma
chine, and thus restores its balance.
The Wright brothers claim this method
is an infringement of their patents and
they now have d suit pending in the
New York courts by which they will
seek to compel CUrtiss to use some
other system of balancing.
The balancing of mOnOplanes, of
which the Frenchman BleriOt's machine
is the best example, is secured partly
by having the big main plane divided at
the center, so that in flight his machine
has something the appearance of a
birds Outspread wings. If his machine
begins to sink on one side he lowers the
wing on that side, thus securing a more
upward push of the air from under
meath. In addition to this he has a LONG
tail-like arrangement attached to the
rear of his flyer, and this assists in bal
ancing, much as a kites tail helps KEEP
it on an even keel
Closely related TO the balancing de-
vice is the steering mechanism. When
the corners of the big planes are lei
down a greater surface on that side OF
the machine is exposed TO the air, and
this has the effect of hating the speed
of the machine on that side. Thus, il
the Tight-hand corners of the big planes
are lowered, the air, pressing against
those corners with more force than il
does at the other ends of the planes
causes the whole machine to swing
around to the right. Meanwhile the real
rudders are turned slightly to further
assist in the turning movement.
A mOnOplane, so called because it has
but one main plain instead of two, is
different in construction from a biplant
Of the Wright and CuTtiss types. II
BleriOts machine the engine is all
cooled and has eight cylinders instead
of four. This gives him a more uni
form distribution of power. In his ma
chine the propeller is placed out II
front so that it bores directly into tn,
air as the machine proceeds, thus pull
ing the flyer along after it instead Of
pushing it from behind. The operate,
sits above the engine and directly be-
/ hind the propeller. He raises and low
ers the machine by changing the angl'
