PROVISIONAL SPECIFICATION left by the said Joseph Alfred Fisher and
Charles Green Spencer at the Office of the Commissioners of Patents on the
28th August 1882.
JOSEPH ALFRED FISHER of 161 Queen Victoria Street London and CHARLES
GREEN SPENCER of 14 Ringeroft Street, Holloway, " IMPROVEMENTS
BALLOONS
ני
IN
Our invention relates to balloons, commonly called fire or Montgolfier balloons,
in which rarefied heated air is used as the inflating agent.
Merits
Hitherto in despite of the many advantages possessed by heated air balloons
over those inflated with hydrogen or coal gas they have not been largely used
mainly on account of the great danger from the fabric being set on fire.
pertaining to heated air balloons are amongst others (1) the rapidity with which
they can be inflated (2) the small cost of inflation, and (3) the ease with which
fuel can be obtained where hydrogen or coal gas is not available.
Now the object of our invention is to so construct a heated air balloon that
there shall be no danger of its being set on fire, thus rendering it suitable for
general use and allowing of its many advantages over the hydrogen or coal gas
balloon being utilized.
The invention consists essentially in combining in a suitable manner asbestos or
non inflamable cloth with any ordinary or suitable fabric so as to provide a
practically fire proof balloon. In carrying the invention into practice the lower
part of such balloon around or near the furnace or heat producer is made of
asbestos cloth or fibre and the upper portion further removed from the source of
heat of any suitable fabric preferably rendered fire proof by means of a solution
of silicate of soda, asbestos paint or other suitable non inflamable compound.
The car and other parts of the balloon are for safety painted with asbestos or
like fire proof paint.

GREEN SPENCER of 14 Ringcroft Street Holloway. "IMPROVEMENTS IN BALLOONS."
Our invention relates to balloons, commonly called fire or montgolfier balloons,
in which rarefied heated air is used as the inflating Agent.
Hitherto in despite of the many advantages possessed by heated air balloons
over those inflated with hydrogen or coal gas they have not been largely used
mainly on account of the great danger from the fabric being set on fire. Merits
pertaining to heated air balloons are amongst others (1) the rapidity with which
they can be inflated (2) the small cost of inflation, and (3) the ease with which fuel
can be obtained where hydrogen or coal gas is not available.
Now the object of our invention is to so construct a heated air balloon that
there shall be no danger of its being set on fire, thus rendering it suitable for
general use and allowing of its many advantages over the hydrogen or coal gas
balloon being utilized.
The invention consists essentially in combining in a suitable manner asbestos or
non-inflammable cloth with any ordinary or suitable fabric so as to provide a
practically fire proof balloon. In carrying the invention into practice the lower
part of such balloon around or near the furnace or heat producer is made of
asbestos cloth or fibre and the upper portion further removed from the source of
heat of any suitable fabric preferably rendered fire-proof by means of a solution
of silicate of soda, tungstate of soda, asbestos paint or other suitable non
inflammable compound.
The car and other parts of the balloon are for safety painted with asbestos or
like fire-proof paint.
Having now described & illustrated our said Invention & the object we seek
to obtain as well as the means we purpose employing to carry the same out, we
wish it to be understood what we claim is―
Firstly. The employment of Asbestos fabricated into a suitable cloth for the
construction of the lower part of the envelope of the balloon (as shown at A on
drawing) which when in action is in close or dangerous proximity to the furnace
or other means employed for generating the necessary heat & which is consequently
liable to damage or destruction by fire.
Secondly. The form or shape of that part of the balloon between points marked
B & C,
In witness whereof we the said Joseph Alfred Fisher and Charles Green
Spencer have hereunto set our hands and seals this 28th day of February
in the year of our Lord one thousand eight hundred and eighty three.
