Improvements in or relating to Gas Stoves or Gas Heating
Apparatus.
I ALEXANDER BROWNE, of 9, Warwick Court, Gray's Inn, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention (a
communication to me from abroad by Joseph Danischevski, of 116 Rue du
Faubourg Poissonnière Paris, France, Engineer) to be as follows:-
This invention consists of new means for heating by gas, according to which, I
utilize simultaneously the incandescence and radiation of the material on which the
flames act.
This invention is based upon a special application of asbestos fibres twisted, or
not, and either coated, or not, with metallic oxides of magnesium calcium,
zinconium, or others, for the purpose of immediately giving heat by utilising the
combustible gas, so as to obtain the maximum amount of heat: which is not the
case with gas stoves as at present constructed.
My special application of asbestos consists in the employment of asbestos fibres,
placed across one another so as to form a kind of trellis work, of large mesh; the
air circulating freely through same.
The asbestos is supported by a metal basket also of large mesh and of such size
to suit the apparatus.
Various attempts have been made to utilize the incandescence of asbestos for
heating, but the asbestos has always been either plaited, felted, or in tufts, which
will not give the best results.
In order that the apparatus may be understood I will refer to the annexed sheet
of drawings in which, Fig. 1. represents a horizontal section, Fig. 2 a transverse
vertical section, and Fig. 3 a front elevation, of an apparatus (of the chimney type
of stove) constructed according to my invention.
Fig. 4. shews a variation of the arrangement of burner and Figs. 5. 6. and 7
shew the application of my invention to a stove.
The incandescent mass of the fire, is supported by a metallic support, or basket a
of large mesh on which is fixed the trellis work b, made of asbestos fibres. This
support is of rectangular form, (see Fig. 1) and in order to increase the
incandescence of the asbestos fibres, these cross the support a, from one end to the
other.
It will be understood that asbestos fibres can be fixel direct, i.e. by their
surrounding the metal, of which the support a is made.
I may also use instead of, or in addition, to, asbestos fibres, any other substance
having similar properties; worked up in a similar form to that described, so as to
allow a free circulation of gas and air through same.
In my arrangement of apparatus the passage of the combustible gas, is indicated
in the drawing by the arrow 1 arriving at the burner c. which latter can be of any
suitable form.
The air enters by the base of the apparatus, the arrows 2 indicating its passage;
a part of this air gets hot and passes into the apartment, in which the stove is
fixed, by the tubes e. (see arrows 3 Figs. 1 and 3). The rest of the air circulates
through the tubular arrangement e', thus heating and increasing the incandescence;
and subsequently the products of combustion circulate in the apparatus by the
special tubes or flues f, and escape by the chimney 9. Arrows 4 indicate the
circulation of the gases or heated air. The register h. fixed on the top of the apparatus

The fire box (so called) is constructed as described with the exception, that the
flues e. are replaced by a number of tubes placed vertically round the box and
in which the air is heated before entering the outside. portion of the stove.
The tubes or flues f. are replaced by the tubes 1. through which the heated air
circulates.
This outside portion is composed of a perforated casing m. surrounding an inner
waved casing n in the interior of which the gas circulates before passing through
the central pipe o. which communicates with the chimney.
The gases give off their heat to the inner surfaces of the casing n which has a
large surface on account of its form, and the air which becomes heated, in contact
with these surfaces, escapes by the holes m.

Improvements in or relating to Gas Stoves or Gas Heating
Apparatus.
I ALEXANDER BROWNE of 9 Warwick Court, Gray's Inn, in the County of
Middlesex, Patent Agent, (a communication to me from abroad by Joseph
Danischevski of 116 Rue du Faubourg Poissonnière, Paris, France Engineer) 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 consists of new means for heating by gas, according to which, I
utilize simultaneously the incandescence and radiation of the material on which the
flames act.
This invention is based upon a special application of asbestos fibres twisted, or
not, and either coated, or not, with metallic oxides of magnesium calcium zinconium
or others for the purpose of immediately giving heat by utilising the combustible
gas, so as to obtain the maximum amount of heat; which is not the case with gas
stoves as at present constructed.
My special application of asbestos consists in the employment of asbestos fibres,
placed across one another so as to form a kind of trellis work, of large mesh: the
air circulating freely through same.
The asbestos is supported by a metal basket also of large mesh and of size to
suit the apparatus.
Various attempts have been made to utilise the incandescence of asbestos for
heating, but the asbestos has always been either plaited, felted, or in tufts, which
will not give the best results.
In order that the apparatus may be understood I will refer to the drawings
accompanying the Provisional Specification in which,
Fig. represents a horizontal section, Fig. 2 a transverse vertical section, and
Fig. 3 a front elevation, of an apparatus (of the chimney type of stovė) constructed
according to my invention.

page_text: Fig. 4 shews a variation of the arrangement of burner and
Figs. 5 6 and 7 shew the application of my invention to a stove.
The incandescent mass of fibre, is supported by a metallic support or basket a
of large mesh on which is fixed the trellis work made of asbestos fibres. This
support is of rectangular form (see Fig. 1) and in order to increase the
incandescence of the asbestos fibres, these cross the support a from one end to the
other.
It will be understood that asbestos fibres can be fixed direct, i.e. by their
surrounding the metal, of which the support a is made.
I may also use instead of or in addition to asbestos fibres, any other substance
having similar properties, worked up in a similar form to that described so as to
allow a free circulation of gas and air through same.
In my arrangement of apparatus the passage of the combustible gas, is indicated
in the drawing by the arrow 1. arriving at the burner & which latter can be of any
suitable form.
C
The air enters by the base of the apparatus the arrows 2 indicating its passage;
a part of this air gets hot and passes into the apartment in which the stove is
fixed, by the tubes (see arrows 3 Figs. 1 and 3). The rest of the air circulates
through the tubular arrangement e thus heating and increasing the incandescence
and subsequently the products of combustion circulate in the apparatus by the
special tubes or flues f. and escape by the chimney g. Arrows 4 indicate the
circulation of the gases or heated air. The register fixed on the top of
the apparatus compels the heated air to redescend by the flues f and to return by
the outside of apparatus to the chimney g. In arranging a register as represented
by the dotted lines at i I can make the gas travel in an inverse direction indicated
by the dotted arrows 5. Fig. 2 shews this circulation.
Figs. 4 and 44 shew a variation of burner provided with a box k having a
perforated surface through which the lighted gas escapes and impinges against a
trellis arranged as aforesaid which is thus rendered incandescent.
Figs. 5, 6 and 7 shew respectively vertical and horizontal sections on the lines 1, 2,
and 3, 4. representing a stove constructed according to my said invention.
The fire box (so called) is constructed as described with the exception, that
the flues e are replaced by a number of tubes e¹ placed vertically round the box
and in which the air is heated before entering the outside portion of the
stove. The tubes or flues are replaced by the tubes through which the heated
air circulates.
This outside portion is composed of a perforated casing m surrounding an inner
waved casing n in the interior of which the gas circulates before passing through
the central pipe o which communicates with the chimney.
The gases give off their heat to the inner surfaces of the casing n which has a
large surface on account of its form, and the air which becomes heated, in contact
with these surfaces, escapes by the holes m.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In improvements in or relating to gas stoves or gas heating apparatus the use
of asbestos fibres made up in the form of trellis or like work substantially as and
for the purpose hereinbefore described and shewn on the drawings.
2. The improvements in or relating to gas stoves or gas heating apparatus
substantially as described and shewn in the drawings.
