page_text: I, JOAQUIM IGNACIO RIBEIRO of No. 4 rua Municipal in the City of Rio de
Janeiro (Empire of Brazil) ecclesiastic 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 :-
:-
My invention relates to apparatus for guiding balloons for aerial navigation as
I will describe referring to the accompanying drawing.
Under a balloon Za revolving shaft A carried in bearings B in a framing Chas
fixed on each end of it a boss Z through which passes a transverse spindle D carrying
two circular propeller blades E having their planes at right angles to each other. On
the shaft A are fitted sleeve pulleys H connected by cords or bands V to corresponding
pulleys H', that can be turned by the hand of an operator situated near the middle
space K.
On the sleeves of H are suitable cams U. acting on arms G on the
transverse spindle D causing this spindle to turn so that one of the blades E presents
its face and the other its edge in the direction of revolution, thereby effecting
propulsion in any desired direction.
To give stability, there are two side planes M and a tail plane N that can be more
or less folded up like fans by means of cords N' worked by winches in the space K.
Also a number of louvre flaps T can be closed or opened by cords R according as
more or less air pressure is desired to act under them. A ballast box P running on
rails can likewise be moved to and fro to give the desired longitudinal trim. For
operating the various adjustments, suitable winches LO and S with pawls or brakes X
are provided within convenient reach of the operator. The whole apparatus is of bird
like form with wings and tail outspread, but the wings have no movement, the whole
propulsion being effected by the propellers E, each of which, instead of two blades
may have four. According as the relation of the rotation of the transverse spindles D
to the revolution of the shaft A is varied by turning the sleeves H, so the direction

page_text: of propulsion is varied, it may be upwards downwards, backwards or forwards, and
the propeller on the one side may thus be made to act differently from that on the
other side, so as to effect steering as may be desired.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
:-
1. Apparatus for guiding balloons consisting of frame work having in front a
horizontal shaft working a pair of propellers, having a pair of side planes, a tail plane
and louvre flaps, that can be more or less folded, a moveable ballast box and a set of
central winches or their equivalents for adjusting the propellers, the planes and flaps
and the ballast, substantially as herein described.
2. In apparatus for guiding balloons, a propeller consisting of a pair of circular
blades fixed at right angles to each other on a transverse spindle revolving while the
shaft which it crosses revolves, substantially as described.
3. In apparatus for guiding balloons, side and tail planes arranged to be folded in
the manner of fans, as herein described.
