page_text: I, GEORGE SEABORN PARKINSON of No. 2, Lilyville Road, Percy Cross, Fulham,
London, Gentleman, do hereby declare the nature of this invention to be as
follows:-
I form a Balloon of any required shape and by aid of an Air-Fan or Blower,
worked by manual or other motive power, I impel it through the air by the principle
of re-action.

page_text: I, GEORGE SEABORN PARKINSON of No. 2, Lilyville Road, Percy Cross, Fulham,
London, Gentleman, 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 :-
I form a Balloon of an elongated or
distinction I call an "Aerial Propeller" and
form.
other suitable shape, and which for
suspend thereto a Car of any desired
-
In this Car I fix an Air-Fan or Blower A. and to the Fan's exit end, I attach a
canvas (or other light material) tubing, made air and gas proof-B.
:
This tubing is then passed into the body of the Propeller through an opening at
the base, and is divided into three channels C and conducted through it and terminates
respectively at the end and at either side of the Propeller, and opens into the air
with expanded or trumpet-shape mouths D.
Any motive power may be used to work the Air-fan, but for simplicity I suggest
that the Aeronaut should sit upon a fixed seat over a fixed (bicycle) wheel E having
a crank on each side and a groove round its circumference. An endless band should
fit into this groove and be conveyed round the spindle of the Air-fan.
By working the cranks of the wheel with his feet, the Aeronaut obtains a power
over the Fan and multiplies its velocity according to the size of the wheel over
which he sits.
The air being drawn into the Fan as into a vortex,. is, by its revolutions, driven
with great vehemence through the above described tubing, and with an irresistable
force finds its three exits into the atmosphere and thus reacts upon the Propeller, by
propelling it at the end and propelling as well steadying at the sides, as in the case
of the tail and fins of a fish.
If preferred a hollow screw with hollow blades, having openings upon one side of
the blades, may be used in lieu of the open mouths, and a rotatory action and impelling
force obtained, by driving the air from the Fan through the tubing and out of these
openings.
Or in place of the canvas tubing arrangement, I make the Air-Fan deliver its
force through any kind of flexible tubing carried in the Car, and capable of
movement to any position required, and thus impel the air in any direction as may be
desired.
By the first arrangement the Balloon acts upon the Car, and by the second plan the
Car acts upon the Balloon.
For steering I attach two cords or rods F to a cross bar passing through the end
exit canvas mouth, properly stiffened to keep its form, and by pulling either cord
or rod, I alter the position of the mouth and so divert the current of driven air which
thus acts a rudder.

page_text: Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that what I
claim is,
1stly. The mode of conveying the air through the body of the Propeller by tubing
as detailed, and thus obtaining a direct propelling power upon the Balloon itself by
the principle of reaction.

2ndly. The use of flexible tubing in the Car for driving the air readily in any
direction as desired.
3rdly. The use of a hollow screw with hollow blades perforated as described.
4thly. The mode of working the Fan by pedal agency as specified.
