Pavement London E.C. do hereby declare the nature of said Invention for "A NEW
OR IMPROVED WARMING STOVE a communication to me from abroad by Gabriele
Boretti, Gentleman of Ardenza near Leghorn in the Kingdom of Italy to be as
follows:-
This stove or heating apparatus is formed by seven cones of white iron situated
one in and above the other all having a common axis and parallel generators The
distance between these generators which are situated in the same plan passing by
the axis is equal which equality is obtained by means of six equal spherical calottes
situated between the superficies of the cones.
A central cylinder the axis of which corresponds to that of the cones forms the
stem of the apparatus to which the cones are attached and is terminated at its lower
end by a large spherical calotte On the convex part of this calotte are placed the
seven discs which form the trunk of the lowest cone and a spherical calotte equal
to those above.
The exterior cone may be made of richer metal to render the stove more elegant.
In order to increase and retain the heat the central cylinder the eight spherical
calottes and the discs are of copper.
By means of a hole at the upper end of the cylinder the apparatus is hung up
and a Petroleum lamp is placed under its axis. The chimney top of the lamp
must not be more than three Centimeters from the large calotte. If gas is used
the distance from the flame to the calotte may be a little more.
After a short time this large calotte becomes heated and communicates its heat
to the discs the calottes and the central cylinder. In addition the hot air fills the
lowest cone and in escaping to rise higher encounters the next cone which in turn
transmits it to the others The heated air in this way passes gradually into all the
cones and when leaving the last escapes into the air.
In this manner it is clearly seen that the hot air is kept during a long period in
the lower part of the room thus raising the temperature.
The cones can be changed or multiplied or made oval so as to introduce two or
more lamps and thus increase the heating power which being obtained from the
lamps used to light the apartment incurs no extra cost.
The hot air from this apparatus does not smell and is not injurious to health so
that it can be breathed by any one innocuously when sleeping or in a closed room,

Pavement London E.C. do hereby declare the nature of said invention for A NEW
OR IMPROVED WARMING STOVE a communication to me from abroad by Gabriel
Boretti, Gentleman of Ardenza near Leghorn in the Kingdom of Italy and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
This stove or heating apparatus is formed by seven cones of white iron S. A. B.
S¹ A¹ B¹ S' A'B' S³ Aª B³ S' A'B' S³ Aº B S" Aª B° situated one in and above
the other all having a common axis and parallel generators. The distance between
these generators which are situated in the same plane passing by the axis is equal
which equality is obtained by means of six equal spherical calottes C¹ D¹ C² D'
C³ D C D C D C D situated between the superficies of the cones.
A central cylinder E F the axis of which corresponds to that of the cones forms
the stem of the apparatus to which are the cones attached, and is terminated at its
lower end by a large spherical calotte G. F. H. Fig 2 Plate L.
'
On the convex side of this calotte aro placed the seven discs I. L. M. N which
form the trunk of the lowest cone and a spherical calotte P equal to those above.
The exterior cone may be made of richer metal to render the stove more elegant.
In order to increase and retain the heat the central cylinder the eight spherical
calottes and the discs are of copper.
By means of a hole E at the upper end of the cylinder the apparatus is hung up
and a petroleum lamp is placed under its axis the chimney top of the lamp must
not be more than three centimetres from the large calotte If gas is used the
distance from the flame to the calotte may be a little more.
In a short time the large calotte G F H. becomes heated and communicates its
heat to the discs I. L M. N. the calottes and the central cylinder In addition the
hot air fills the lowest cone and in escaping to rise higher encounters the next cone
which in turn transmits it to the others.
The heated air in this way passes gradually into all the cones and when leaving
the last escapes into the air.
In this manner it is clearly seen that the hot air is kept during a long period in
the lower part of the room thus raising the temperature.
The cones can be changed lessened in number or multiplied or made oval so as
to introduce two or more lamps and thus increase the heating power which being
obtained from the lamps used to light the apartment incurs no extra cost.
Figs 1. 2. 3. 4. Plate II show a modification in the form of the apparatus for
three lamps in which the intermediate cones discs and calottes are dispensed with
only the central calotte l i o n m and the outer cover c. a. e. g. h. f. b. d. being
retained.
The hot air from this apparatus does not smell and is not injurious to health so
that it can be breathed inocuously when sleeping or in a close room,

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
A warming apparatus or stove composed of one or more cones of copper or other
metal with calottes and discs to retard and use to hot air of oner or more lamps or
gas flames in heating or warming an apartment.
