PROVISIONAL SPECIFICATION.
Improvements in Aërial Machines.
I GEORG GABRIELII of Carl Johans Gade 5, Christiania in the Kingdom
of Norway, Merchant do hereby declare the nature of this invention to be as
follows:-
My invention relates to aĕrial machines and comprises a balloon made in two
parts and secured by ropes and stays to the car which is in the form of the hull
of a vessel and is also made in two parts. The fore part is connected to the after
part by a pivot for the purpose of steering the machine through the medium of
a rod actuated by a steering wheel in the after part. The machine is propelled
by means of paddles and a screw driven by a suitable motor. The paddles
are arranged to feather by means of projections on the sides of the vessels and
suitable stops. The screw is arranged so that it can be moved in the arc of a
circle in order to assist the steering of the machine. I find it advantageous to
arrange the driving gear so that either one or both of the paddles can be operated
together or separately.

COMPLETE SPECIFICATION.
Improvements in Aerial Machines.
[, GEORG GABRIELII, of Carl Johans Gade 5, Christiania, in the Kingdom
of Norway, Merchant, 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 relates to an improved aërial machine which is of a more
convenient form and more easily steered than aërial machines as heretofore
constructed.
My said invention is illustrated in the accompanying drawing, in which
Figure 1 is a side elevation of my improved aërial machine, and
Figure 2 is a plan.
AA are the two parts of a balloon which is filled with hydrogen or other
suitable gas and B' B' are the two parts of the car which is suspended from the
balloon by ropes, straps or the like a, a, the said car being made of plates of aluminium
or other light material on suitable frames and lined with bamboo or other light
material. The fore part B¹ of the car has fixed to it a rod b pivoted upon a stud c
upon the bottom of the after-part of the car in such a manner that the fore part B'
can through the medium of a bar & be turned to starboard or port and thereby
cause the steering of the ship in one or other direction. The movement of the
bar d is effected by lines f, f passing over blocks or pulleys e, e and connected
with a drum operated by a steering wheel g. Toothed gearing may, however, be
used for moving the fore part of the car if desired.
h is a motor by which the propulsion of the machine is effected the said motor
rotating the shaft i carrying a screw k and also driving paddles upon the
shafts m, m.
The shaft is connected to the motor by a universal joint and is
connected by lines f¹, passing over pulleys or blocks e', el to the drum of the
steering wheel in such a manner that when the said steering wheel is moved to
ונ...rD

page_text: move the front part of the car to port or starboard the screw will be moved to
starboard or port and thus facilitate the steering. The paddles which are placed
at the sides of the machine are carried on rods 1, and are adapted to feather so
that during their revolution those paddles which are moving in the direction in
which the machine is travelling shall present their edges to the air and so not
impair the efficiency of those paddles which are operating against the air. For
this purpose the opposite blades l', l' of the paddles are fastened in pairs to the
rod in the shaft m so that when one paddle is cutting the air, the other is acting
against the same.
The turning of the blades at the proper time is effected by tappets n, n placed
on the sides of the car and so arranged that at the point where the efficient action
of each blade ceases it strikes against the tappet and is turned about one fourth of
a revolution, stops o, o on the hubs of the paddles preventing the blades from being
moved too far; at the same time that a blade is turned with its edge to the air,
the opposite blade is turned with its face to the air. The mechanism for trans-
mitting motion to the paddles from the motor must be so arranged that either
paddle can be stopped while the other is working.
The object of making the balloon in two parts is that the front part thereof may
follow the movements of the fore-part of the car for steering, and for this purpose
the line, of the division approximately coincides with the joint between the
two parts of the car. The balloon is steadied relatively to the car by the stays p¹, p³
and by the bowsprit p³.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
(1.) An aërial machine having a balloon in two parts, a car suspended from the
said balloon also in two parts pivotted together, the front part of the said car
being provided with a bowsprit to which lines for steadying the balloon relatively
with the car are connected and paddles and a screw for propelling the machine,
the said paddles being so arranged that when the blades are moving in the same
direction as the machine they will present their edges to the air so as not to
impair the efficiency of the blades acting upon the air, substantially as described.
(2.) In an aërial machine having the balloon and the car each made in two parts
so that the fore parts can move or pivot relatively to the rear parts and which is
driven by paddles having feathering blades and a screw, arranging the said screw so
that it can be moved to one side or the other according to the direction in which
the fore part of the machine is used relatively with the rear part for facilitating the
steering of the said machine substantially as described.
(3.) The improved aërial machine consisting of the parts constructed and com-
bined substantially in the manner herein before described and illustrated in the
accompanying drawing and operating as, and for the purposes, set forth.
