A Flying Machine.
WILLIAM FROST Carpenter and Builder Saundersfoot Pembrokeshire do hereby
declare the nature of this invention to be as follows:-
The flying machine is propelled into the air by two reversible fans revolving
horizontally. When sufficient height is gained, wings are spread and tilted by
means of a lever, causing the machine to float onward and downward. When low
enough the lever is reversed causing it to rise upward & onward. When required
to stop it the wings are tilted so as to hold against the wind or air and lowered by
the reversible fans. The steering is done by a helm fitted to front of machine.

WILLIAM FROST Builder Saundersfoot Pembrokeshire 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 :-
The flying machine is constructed with an upper and lower chamber of wire work
covered with light waterproof material. Each chamber formed sharp at both ends
with parallel sides. The upper large chamber to contain sufficient gas to lift the
machine. In the centre of upper chamber a cylinder is fixed in which a horizontal
fan is driven by means of a shaft and bevilled gearing worked from the lower
chamber. When the machine has been risen to a sufficient height, then the fan is
stopped and the upper chamber which has wings attached is tilted forward causing
the machine to move, as a bird onward and downward. When low enough it is
again tilted in an opposite direction which causes it soar upward and onward when
it is again assisted if necessary by the fan. The steering is done by a rudder at
both ends.
The flying machine is constructed with an upper and lower chamber of wire work
covered with light waterproof material. Each chamber formed sharp at both ends
with parallel sides. The upper chamber as shown on drawings at B. to contain
sufficient gas to lift the machine. In the centre of upper chamber B a cylinder is
fixed in which a horizontal fan as shown at A is driven by means of a shaft as
shown at H and bevilled gearing as shown at G worked from the lower chamber-as
shown at K.
When the machine has risen to a sufficient height, then the fan A is stopped
and the upper chamber B which has wings attached is tilted forward, by lines
as shown at E causing the machine to move as a bird onward and downward.
When low enough it is again tilted in an opposite direction which causes it to soar
upward and onward, when it is again assisted by the fan A. if necessary.
The steering is done by a rudder at both ends as shown at C and D.

page_text: 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. The seperate motive powers, namely the gas for lifting the machine only and
the horizontal fan or regulator as shown at A which lifts those who are in the
machine, and when reversed it assists the down motion or weight on the wings.
2. The tilting of the upper chamber & wings as shown at B which causes the
machine to move onward and downward, and when the tilting is reversed it moves
onward & upward. This is done by wire lines as shown at E passing over a wheel
as shown at F and turned either way as required.
3. The working of the horizontal fan in the cylinder as shown at A. This is
done by two driving wheels as shown at G with bevilled friction gearing fixed to a
shaft as shown at H and turns the fan. The driving wheels are fixed on a
suspended frame I which keeps the shaft H in a straight position when the tilting
takes place.
4. The steering which is done by a rudder as shown at C fixed on front end of
upper chamber in a vertical position and is moved either way by lines as shown
at J and worked from lower chamber. A tail is fixed on the hinder end to assist
the steering & tilting as shown at D.
5. The passenger or lower chamber as shown at K is protected from the force of
the atmosphere with wire work & waterproof covering with suitable ventilation &
lights.
