Improvements in and relating to Aëronautic Apparatus.
I, CARL HEINRICH OSCAR ROEPER, of 66 Hallerstrasse, Hamburg, in the
Empire of Germany, Civil Engineer, do hereby declare the nature of this invention
to be as follows .-
-
This invention relates to aéronautic apparatus and consists in the improvements
hereinafter described
My acronautic apparatus has an aeroplane or propped arched bearing sail from
which the vessel is suspended by means of a stable frame-work or structure. At
its front end the vessel carries two propellers, arranged side by side and turning in
opposite directions with regard to one another. The said propellors are actuated
by a motor located in the vessel.
The air tight tubes of the bearing construction may be of such dimensions as to
enable the apparatus to float upon the water, and so atranged, that the apparatus
may obtain upon the surface of water the necessary speed for rising, and may
descend thereon.
The before mentioned parts are arranged in such positions, that, first, the
resultant of the air pressure normal to the surface of the bearing sail, second, the
resultant of the air pressures, which are acting on the other parts of the apparatus
and which are produced by its forward movement, and third, the resultant of the
nir pressure generated behind the propellers approximately pass through the centre
of gravity of the whole apparatus.
For turning the apparatus around its centre of gravity in a horizontal plane a
steering sail is provided rotatable around the mast
For tuining the apparatus in a vertical plane I provide a rudiler This rudder
consists of a pismatic body of rhomboidal cross section and it is moved by parallel-
motion iods. These rods are moved by means of a hand lever provided with a
fixing latch. The hand lever is by means of springs forced into its middle position,
which corresponds to the middle (horizontal) position of the rudder, so as to
counteract the momentum of the air pressure produced on the rudder by the
forward movement of the apparatus.
To the rearwardly directed point of the steering sail the extremities of a cord
(of silk for example) are fixed. This cord passes over guide-pulleys and the
steering wheel. The rotation of the steering wheel may be effected by means of a
friction cone keyed on the shaft of the steering wheel, in co-operation with the friction
aic piece or quadrant which latter can be inoved along the cone by means of a
hand lever during which mampulation a pulley regulated by spring power exerts
the requisite pressure from the arc to the couc. The steering wheel is enabled to
perform two entire revolutions. The cord-groove in said steering wheel, is formed
according to a helical line with changing diameter of such a kind, that the steering
cord is always kept in the uniform tension in spite of the variable sum of the two
linear extensions.
The two hand levers are arranged one at each side of the place occupied
by the driver of the aeronautic apparatus, su that the driver is enabled to turn
with both his hands the said levers without difficulty and without changing his
position.

page_text: A stable sail is provided adapted to counterpoise sudden gusts. I also provide a
suitable vent hole for catching the air necessary for refrigerating the motor.

Improvements in and relating to Aeronautic Apparatus
I, CARL HEINRICH OSCAR ROEPER of 66 Hallerstrasse, Hamburg, in the
Empire of Germany, Civil Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention refers to improvements in and relating to aeronautic apparatus
and consists in certain novel features of construction and combination of parts, as
will be hereinafter fully described.
The aeronautic apparatus, provided with my improvements is diagrammatically
illustrated in the accompanying drawings, in which:
Figure 1 is a side view of the improved apparatus.
Figure 2 is a front view of the complete nilangenient.
Figure 3 is a side view of the steering arrangement diawn to a somewhat
enlarged scale.
Figure 4 is a plan of the same and
Figures 5-9 shew the steering wheel in different positions of the steering
sail.
Similar letters of reference indicate corresponding parts throughout the several
views.
My aeronautic apparatus has an aeroplane or propped arched bearing sail a,
from which the vessel bis suspended by means of a stable frame-work or structure.
At its fiont end the vessel carries two propellers c, arranged side by side and
turming in opposite directions with regard to one another. The said propellers c
are actuated by a motor located in the vessel, but not especially shown in the
drawing.
The air tight tubes d of the bearing construction may be of such dimensions as
to enable the apparatus to float upon the water, and so arranged, that the apparatus
may obtain upon the surface of water the necessary speed for sing and may
descend the con.
The before mentioned parts ate auanged in such positions that first, the
resultant of the air pressure normal to the surface of the bearing sail a, second,
the resultant of the air pressures, which are acting on the other parts of the
apparatus and which are produced by its forward movement, and third, the
resultant of the an pressure generated behind the propellers c approximately pass
through the centre of gravity of the whole apparatus.
For turning the apparatus around its centre of gravity in a horizontal plane a
steering sail e is provided rotatable around the mast e' es.
For turning the apparatus in a vertical plane 1 provide the rudder /.
This rudder is a prismatic body of rhomboidal cross section and it is moved by
the parallel motion rods yy. These rods g g are moved by means of a hand
lever provided with a fixing latch, which latter has not been especially shown in
the drawing. The hand levet is by means of springs in forced into its middle
position, which corresponds to the middle (horizontal) position of the rudder, so
as to counteract the momentum of the air pressure produced on the rudder by the
forward movement of the apparatus.

cords (of silk for example) are fixed This cord passes over guide pulleys r
and the steering wheel S. The rotation of the steering wheel S may be effected
by means of a friction cone k keyed on the shaft wo of the steering wheel S, in co-
operation with the friction arch piece k', which latter can be moved along the
cone by means of a hand lever P, during which manipulation a pulley t regulated
by spring power exerts the requisite pressure from A to k. The steering wheel S
is enabled to perform two entire revolutions. The cord-groove in said steering
wheel, as may be seen from Figures 5 to 9 of the drawing, is formed according to a
helical line with changing diameter of such a kind, that the steering cords passing
from to Sr and back to e 18 always kept in the uniform teusion in spite of the
variable sum of the two linear contents e³-r.
The two hand levers and are arranged one at each side of the place occupied
by the driver of the aeronautic apparatus, so that the duve is enabled to turn.
with both his hands the said levers without difficulty and without changing his
position.

catching the air necessary for refrigerating the motor.

tion, and in what manner the same is to be performed, I declare that what I
claim 18-

resultant of the au pressure upon and norinal to the surface of the bearing sail, the

the forward movement of the vessel, and the resultant of the air pressure generated
behind the propellers will pass through the centre of gravity of the apparatus,
substantially as described.
