Improvements in Open Gas Fires or Stoves.
We, SAMUEL VICKREY BIRD of St. Pauls Road, Balsall Heath near the City
of Birmingham, Manager of Works, and JOSEPHI SYKES WOOD of Hingeston
Street, in the aforesaid City, Foreman of Works, do hereby declare the nature
of this invention to be as follows:-
This invention relates to open gas fires or stoves, and is an improvement upon
application for Letters Patent made by us and dated the 27th day of May 1891
No. 8983.
Our present invention consists primarily, in providing or fitting open gas fires or
stoves, with supplementary or additional canopies, whereby the heated air
immediately before the open front, is (in a pure state) conducted into the room,
instead of being drawn into the fire by the draught created in the said fire place,
consequent upon combustion.
Thus in an ordinary open gas fire, a simple canopy is employed at the upper
boundary part of the opening, which collects or gathers in air, to the fire place,
for combustion.
Now the air in front of, or approximate to, the open front, is warmed by radiant
heat, and, if allowed to there remain, is only drawn into the fire, without heating
room.
The object of our invention is to so construct an open gas fire or gas stove,
by adding thereto an additional canopy, that the air, heated by radiation, and
emitted from the open front of the fire place, shall be utilized more efficiently
in warming and heating apartments.
In carrying out our invention, in connection with a gas fire, the fire place or
chamber is fitted or supplied with combination fuels of any approved constructions,
such as are described in the Specification of our application for Letters Patent as
aforesaid.
Thus, the lower part of the fireplace, has Bunsen's burners fitted therein, and
over and above the said burners, combination fuels, or asbestos, or the like, is
placed.
The upper boundary edge of the opening of the said front, has an ordinary
and slightly projecting hood or canopy, which collects and prevents the products of
combustion, generated within the combustion chamber, from passing outwardly into
a room or chamber wherein the fire is located.
Directed above the first named hood or canopy, and projecting over the front
of the opening, is a secondary hood or canopy, with the front part of it, projecting
outwardly into the room, to an extent sufficient to collect thereby, a very large
part of the air heated by radiant heat emanated from the fire, and which heat, on
ascending, instead of being drawn into the fire, is conducted under the canopy,
and from thence conducted into the room or apartment wherein the fire is located.
Thus, between the top of the canopy proper, or that bordering the top side of
the opening of the fire-place. is an upwardly directed channel, covered in, and
overhung at its front, by a projecting canopy, which collects the heated air as it
ascends as aforesaid, and conveys the same directly into the room, either through
an open topped channel, or through other channels or conduits, as circumstances
may require.
To protect surrounding woodwork or the like, an intervening space above the
secondary canopy is left, so that the heat imparted to the metal work of the
surrounding framing by conduction, is stopped off from the intervening media,
hence the protection of surrounding materials effected by heat.

page_text: The front of the fire place may be provided with a roller screen, which may be
worked from top, bottom, or sides of the fire place aperture, either in the form of
an incombustible woven substance, such as asbestos, colored or tinted as may be
desired, or by a flexible panel in the form of folding strips of metal or wood, united
together by hinged joints, which admit of the said panel being traversed into a
hidden recess made to receive it.
If necessary, the additional canopies may be made in the form of flexible
panellings, which can be drawn, or pushed in as may be required, and so also, might
the ordinary canopy be so constructed.
The exit to the canopy outlet, may be pierced, or so constructed, to effectually
and efficiently diffuse the heated air passing through it.
As a further form of our invention, we may make the open gas fires in the form
of an upright pillar or pedestal with four or other number of sides, and with each
side fitted or provided with a gas fire or opening, having located within it,
combination, asbestos, or other fuel, heated by a Bunsen or other burners located
under them, and with each opening or open front, provided with additional or
supplementary canopies, or canopies and screens of the construction and character
as hereinbefore referred to, in respect to an ordinary or single open gas fire.
By arranging open gas fires in a series or within a block, the same can be used
in the middle of a room, alike unto a stove having pierced sides fitted with gas fires
or fuels.
The outlets of the said series of gas fires in a block, may be in common, or they
may be separate, and further, back partitions or divisional walls between each
fire, are arranged so that the open fires are independent of each other.

Improvements in Open Gas Fires or Stoves.
We SAMUEL VICKREY BIRD of St. Pauls Road, Balsall Heath, near the City of
Birmingham, Manager of Works, and JOSEPH SYKES WOOD of Hingeston Street,
in the aforesaid City, Foreman of Works 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 relates to open gas fires or stoves, and an improvement upon
Letters Patent granted to us and dated the 27th day of May 1891 and No'd 8983.
Our present invention consists primarily, in providing or fitting the said open
gas fires or stoves, and gas fires and stoves generally with supplementary or
additional canopies, whereby the heated air immediately before the open front, is
(in a pure state) conducted into the room, instead of being drawn into the fire by
the draught created in the said fire place, consequent upon combustion.
Thus, in an ordinary open gas fire, a single canopy is employed at the upper
boundary part of the opening, which collects or gathers-in air to the fire place for
combustion.
Now the air in front of, or approximate to, the open front, is warmed by radiant
heat, and, if allowed to there remain, is only drawn into the fire, without heating
the room.
The object of our invention is to so construct an open gas fire or gas stove, by
adding thereto an additional canopy or canopies, that the air heated by radiation,
and emitted from the open front of the fire place, shall be utilized more efficiently
in heating and warming apartments.

page_text: In carrying out our invention in connection with a gas fire, the fire place or
chamber is fitted or supplied with combination fuels of any approved constructions,
such as are described in the Specification of our said Letters Patent as aforesaid.
Thus the lower part of the fire place has Bunsens or other burners fitted therein,
and over and above the said burners, combination fuel, or asbestos, or the like is
placed.
The upper boundary edge of the opening of the said front has an ordinary and
slightly projecting hood or canopy, which collects the products of combustion
generated within the combustion chamber, and prevents them from passing out-
wardly into a room or chamber wherein the fire is located.
Directed above the first named hood or canopy, and projecting over the front of
the opening, is a secondary hood or canopy, with the front part of it, projecting
outwardly into the room, to an extent sufficient to collect thereby, a very large
part of the air heated by radiant heat emanated from the fire, and which heat, on
ascending, instead of being drawn into the fire, is conducted under the canopy, and
from thence conducted into the room or apartment wherein the fire is located.
To protect surrounding woodwork or the like, an intervening space above the
secondary canopy is left, so that the heat imparted to the metal work of the
surrounding framing by conduction, is stopped off from the intervening media,
hence the protection of surrounding materials effected by heat.
If necessary the additional canopies may be made in the form of flexible
panellings, which can be drawn out, or pushed in, as may be required, and so also
might the ordinary canopy be so constructed.
The exit to the canopy outlet, may be pierced, or so constructed to effectually
and efficiently diffuse the heated air passing through it.
As a further form of cur invention, we may make the open gas fires, in the form
of an upright pillar or pedestal, with four or other number of sides, and with each
side fitted or provided with a gas fire or opening, having located within it,
combination, asbestos or other fuel, heated by Bunsen or other burners located
under them, and with each opening or open front, provided with additional or
supplementary canopies, of the construction and character as herein before referred
to in respect to an ordinary or single open gas fire.
By arranging open gas fires in a series or within a block, the same can be used
in the middle of a room.
The outlets of the said series of gas fires in a block, may be in common, or they
may be separate, and further, back partitions or divisional walls between each
fire are or may be arranged, so that the open fires are, or may be, independent of
each other.
Figure 1 of the accompanying drawings, represents in front elevation, an open
gas fire or an open gas stove, constructed according to our cited Letters Patent
and provided with improvements made according to our present invention.
The said open gas fire or stove has an exterior embellishment or framing, made
of wood or other like material, and which is protected from the radiant, conducted,
and ascending heat of the fire place by a supplementary or additional hood or
canopy, and also an intervening space, having overhanging flanges, disposed
or arranged contiguous with the inner boundary edges of the said wood or other
framing, which, if unprotected, would be liable to become discoloured, the polish
blistered, and the same possibly burnt, and further, the additional canopy and
intervening space serves as a means for collecting the heated air surrounding the
fire place, and conducting the same into an apartment, or room to be heated.
Figure 2 represents a longitudinal vertical section of the said open gas fire, or
open gas stove, upon the dotted lines A. B. Figure 1.
Figure 3 represents a transverse horizontal section of the said open gas fire,
with its fittings and cognate parts upon the dotted lines C. D. Figure 2.
Figure 4 represents a horizontal section of the said fire box part, upon the dotted
lines E. F.
The same letters of reference indicate corresponding parts in Figures 1 to 4.

page_text: a is the fire box, consisting of a rectangular shaped metal casing, open at front,
and bottom, and provided at back with a radiating and regenerative fire brick
slab b, for supplying the upper portion or portions of the flame or flames, emanating
from the gas burner c, with heated air, which re-animates the said flames, hence
the production of great heat, which plays upon the fuel d, which projects from the
back of the slab b
The said fire box consists of a closel back a², flue outlet a³, a closed crown
part a', a semi-closed bottom a³, an open front a, with a hopper-shaped entrance a
having a hood a, depending front side a, and front plate a, between which, and
the part a, is a space a", down which the screen or movable panel, slides, when
the same is out of use.
The outside boundary edges of the fore part of the expanding or hopper shaped
front a', are fitted with a box flange as, having a houndary web a, and intermediate
bearing parts a¹, which impinge and abut at intermediate points, upon the front
side of the enclosing wood framing e, which is protected from ascending radiant
heat, by a deflecting flange, and horizontally disposed hoody, carried at the
upper inside crown parts of the hopper shaped front a', which is the entrance to
the gas fire or stove.
g is an additional canopy or heated air collecting hood, having a mouth entrance g*,
and an open back, leading to an inwardly and upwardly directed arm flue g³,
having a piercing at its inner side for taking away the radiant heat emanating
from the fire box, or the crown of the fire box and fitted upon the said arm flue
is a conducting flue or passage h, with the exit of it, directed to the perfora-
tions, of a grating framing i, encompassing the top and sides of the wood framing e,
although the said Hue h, is only directed to the top piercings of the grating framing,
whilst heated air conducted through the intervening space j, located between the
flange a, and the top side of the hood g, enters the cavity or space k, at the back
of the front of the frame work, and then ascends, and passes into a room
through the top and portions of the side piercings of the grating framing i, so that
the heated air lying immediately within the field at the entrance a', is collected,
and conducted upwardly through the mouth, g², and is from thence conveyed up
arm g³, and through flue, ³, through the piercings, whilst the heated air which
escapes from passing up the supplementary or additional horizontal hood g, is
caught by the outstanding flange a", and by it, the said air is conducted through
the intervening passages, which leads to the chamber k, and from thence ascends
through the piercings, or portions of the piercings i³, of the grating frame i.
It will be observed that the said supplementary additional hood or cowl g,
and intervening space j, above it, entranced by the horizontal flange ale, not only
collects the heated air, and conveys the same into a room, which would under
ordinary circumstances, pass up the Hue a³, of the fire box, and be lost, but prevents
the heating of the surrounding frame, which may be composed of wood or other
material, or prevents the surface of the frame becoming scorched or blistered.
Figure 5 represents partly in vertical section, and partly in elevation, a block
open fire or stove, constructed according to a further form of our invention.
Figure 6 represents a horizontal section upon the dotted lines G. H Figure 5.
In this arrangement of our invention the framing of the heating appliance, is
arranged in the form of a four-sided pillar or erection, with open fires located
within the middles of the whole of the four sides, so that the same represents a
block of fires, presented in all directions.
Instead of the block fire having four sides, it may have two, three, five or any
desired number.
e is the general pillar framing, having four sides, pierced with openings a', and
fitted with fire boxes a, which have at the backs of them, regenerative fire brick
slabs b.

The upper parts of the openings may have primary and supplementary hoods a³, g
the latter also fitted with passages, whilst the said secondary hoods
above them openings i.

page_text: Leading to the fire boxes are air feed flue c.
The products of combustion and heated air evolved in the fire boxes are passed
over the tops of the slabs, and from thence conducted into the interior k, encom-
passed by the walls of the heating erection, which has a crown e', and grating
piercings e, through which latter the heated air passes into an apartment or room.
Figure 7 represents in transverse section an all-round gas fire pillar heating
apparatus, constructed according to a further form of our invention.
e is the general framing, a' an all-round opening, and as are pillars or vertical
stays, for supporting the upper and lower circular parts of the structure. k is a
chamber or inside space, whilst b is a fire brick back, over or through piercings in
which, the products of combustion generated, pass to the said chamber k.
If desired, the products of combustion given off from the burner may pass
through a flue, and not into an apartment or room with the heated air.
In this case, the erection Figure 7, is preferably fitted with primary and
supplementary cowls or hoods, and further, it will be understood that the front
elevation of the said stove Figure 5, will be similar or alike unto the front elevation
of the stove Figure 1 of the preceding arrangement.
Instead of the entrances to the open fires as in Figures 1 to 6 having supple-
mentary or additional hoods at the upper parts of them, they may have intervening
spaces, outwardly terminated by vertical flanges at their sides, and through which
spaces, heated air may pass.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
First In an open gas fire or gas stove, providing or fitting the top of the
opening in front of the fire or fires or in front of the fire box or fire boxes, and
above the ordinary hood or hoods, if employed, with a supplementary hood or
hoods, or a brought forward hood or hoods with open back, or open back parts,
fitted with air channels, flues or passages, which lead into a room or apartment to
be heated, as set forth.
Secondly-In open gas fires or open gas stoves, providing or fitting the tops
of the openings of the same, with a brought forward hood or hoods, and over-
hanging flanged opening or openings g, j, and which air collecting expedients are
arranged above the fire box hood, as set forth.
Thirdly-In open gas fires or gas stoves, fitting or providing the top and sides
with flange-bounded air openings or passages, as set forth.
Fourthly-In open gas fires or gas stoves, constructing the fronts of the upper
parts as described and set forth in Figures 1, 2, and 3.
Fifthly-In open gas fires or stoves, fitting or providing the sides of the erection,
framing or casing, with two or more open fires, arranged, back to back, or in the
form of a block erection, with fires all round or with fires upon each side,
substantially as described and set forth in Figures 5 and 6.
Sixthly In block open gas fires or gas stoves, making the same in the form of
a pillar, with an open fire all round, or approximately all round, substantially as
described and set forth in Figure 7.
