formed between the spokes and hingedly
connected to every other spoke are oppo-.
sitely disposed triangular flaps or wings 25
which normally diverge downwardly and
5 are supported in such position by triangular
stops 20 suspended from the spokes to which
the flaps are connected. With the flaps 25
in their normal positions, as shown in Figs.
1 and 2, it will be apparent that the upward
10 movement Qf the machine will not be re-
tarded. When, however, the machine is
descending these flaps 25. will be closed
against the adjacent spokes 24 by pressure
of air between the diverging flaps and, as
15 soon as said flaps are moved to closed posi-
tion, they will prevent air from passing be-
tween the spokes and said air will thus be
displaced downwardly and the descent of
the machine retarded. Should it be desired
20 to use the flaps for sustaining the machine
while gliding, the casing 10 can be adjusted
angularly so as to incline the sustaining
plane upwardly and forwardly. This is of
course to be done after the wheels 19 and 21
25 have ceased to rotate. After the parts have
thus been adjusted it will be apparent that
the pressure of air upon the lower and up-
wardly and forwardly inclined surface of
the plane will cause the flaps 25 to swing
3' upwardly against the spokes 24 and thus
form a continuous sustaining surface.
It is to be understood that the mechanism
herein described can be applied to any .form
of car and the showing in the drawings is
merely intended to designate the car dia-
grammatically.
What is claimed is:
1. The combination with a helicopter of
40 sustaining means interposed between the ele-
vating wheel and the car thereof and includ-
ing a rim concentric with the axis of rota-tion of the elevating wheel, spokes radiat-
ing to the rim and substantially T-shaped
in cross section, angular flaps hingedly con-
nected to alternate spokes and adapted, 4
when swung to active positions, to bear up-
wardly against the lower faces of the side
portions of said T-shaped spokes, and a tri-
angular spacing device interposed between
the flaps of each pair for holding said flaps 5o
normally spaced apart at their lower edges,
said spacing devices being fixed relative
to the spokes carrying the flaps.
2. The combination with a helicopter, of
sustaining means interposed between the ele- 55
eating wheel and the car thereof and includ-
ing a rim concentric with the axis of rota-
tion of the elevating wheel, spokes radiat-
ing to the rim and substantially T-shaped
in cross section, angular flaps hingedly con- 60
nected to alternate spokes and adapted,
when swung .to active positions, to bear up-
wardly against the lower faces of the side
portions of said T-shaped spokes, a trian-
gular spacing device interposed between the 65
flaps of each pair for holding said flaps
normally spaced apart at their lower edges,
said spacing devices being fixed relative to
the spokes carrying the flaps, each flap,
when in closed or active position, contacting 70
throughout its length with the adjacent
spokes, and means for adjusting the rim and
the parts connected thereto angularly rela-
tive to the car.
In testimony that I claim the foregoing 75
as my own, I have hereto affixed my sig-
nature in the presence of two witnesses.
