page_text: LETTERS PATENT to Samuel Jabez Goode, of Aston, near Birmingham,
.
in the County of Warwick, Machinist, for the Invention of "IMPROVE-
MENTS IN GAS STOVES, AND THE APPLICATION OF THE SAME TO THE VENTILATION
OP BUILDINGS."
Sealed the 24th October 1856, and dated the 30th June 1856.
PROVISIONAL SPECIFICATION left by the said Samuel Jabez Goode at the
Office of the Commissioners of Patents, with his Petition, on the
30th June 1856.
I, SAMUEL JABEZ GOODE, of Aston, near Birmingham, in the County of
Warwick, Machinist, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN GAS STOVES, AND THE APPLICATION OF THE SAME TO THE
VENTILATION OF BUILDINGS," that is to say:-
My improvements consist in constructing gas stoves in the manner herein-:
after explained. When I do not wish the products of combustion to enter the.
room to be heated, I form a chamber at the lower part of the body of the:
stove, by means of two plates, situated horizontally at a short distance from
one another, and extending across the body of the stove. A gas burner, the.
top of which is covered with wire gauze, is situated under this chamber, and
gas mixed with air is burned at the summit of the said burner. The flame.
plays upon the bottom of the chamber and heats the air within. A series.

page_text: of tubes, opening at bottom into the room, communicate at top with the
chamber, and supply a current of air, which, after being heated, passes out
of the chamber by perforations at its top. That portion of the stove in which
the burner is situated is closed, excepting that a series of perforations, per-
mitting sufficient air to support combustion, are made at its bottom, and a
flue passing from its top carries away the vitiated air. When there is no
objection to the passage of the products of combustion into the apartment to
be heated, I cause the flame of gas mixed with air to pass up a conical flue;
the said flue enters a chamber, constituting the body of the stove, and air
from the apartment, together with the flame and heated air from the burner,
pass into the said chamber. The heated air passes from the said chamber into
the apartment by means of perforations in its top. In applying gas stoves to
the ventilation of buildings, I place the said gas stoves at or near the top of
the building, and by the ascending current from the stove the ventilation of
the building is effected.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Jabez Goode in the Great Seal Patent Office on the
29th December 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
JABEZ GOODE, of Aston, near Birmingham, in the County of Warwick,
Machinist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of June, in the year of our Lord One
thousand eight hundred and fifty-six, in the twentieth year of Her reign, did
for Herself, Her heirs and successors, give and grant unto me, the said
Samuel Jabez Goode, Her special licence that I, the said Samuel Jabez
Goode, my executors, administrators, and assigns, or such others as I, the
said Samuel Jabez Goode, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
IN GAS STOVES, AND IN THE APPLICATION OF THE SAME TO THE
VENTILATION OF BUILDINGS," upon the condition (amongst others) that I, the
said Samuel Jabez Goode, my executors or administrators, by an instrument
in writing, under my, or their, or one of their hands and seals, should
MENTS

page_text: particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed; and cause the same to be filed-
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Jabez Goode, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :—
My Invention consists of the improvements in gas stoves, and in the appli-
cation of the same to the ventilation of buildings, herein-after particularly
described, and illustrated in the accompanying Drawing.
Figure 1 represents, in vertical section, a gas stove constructed according
to my Invention. a is the outer body of the stove; and b, a chamber opening
at top into the atmosphere by the perforations at c, and communicating with
the air of the room by means of the tubes d, d; e is a gas jet, provided with a
chimney, the top of the said chimney being closed with wire gauze. Gas
from the said jet e passes through the wire gauze at the top of the chimney,
mixed with atmospheric air, and is ignited above the wire gauze. The flame
strikes against the bottom of the chamber b, and, by heating the same, deter
mines an upward current of heated air through the tubes d, d, chamber 6, and
perforations c. The flame and products of combustion striking against
the bottom of the chamber b, pass up the annular space f, between the body
of the stove a and chamber b, and pass away by the flue g. In addition to
the current of heated air arising through the chamber 6, the outer casing or
body of the stove a heats the air in contact with it, and also radiates heat
into the room. By the construction described none of the products of com;
bustion enter the room, and the air of the said room is not vitiated by the use
of the stove.
Figure 2 represents, in vertical section, a modification of my Invention. In
this modification the heated air delivered from the stove into the room is
supplied from the atmosphere external to the room. h, h, are the gas burners;
i, the chamber heated by the said burners; k, the body of the stove; and 1,
the flue by which the products of combustion are carried away; m is a flue,
communicating between the chamber i and the atmosphere, external to the
room in which the stove is used. When the stove is in action, air from the
external atmosphere, entering by the tube m, becomes heated in the chamber
i, and passes into the room through the perforations in the top of the stove.
In order to prevent the bottom of the chamber i becoming so strongly heated
as to communicate an odour to the air, I sometimes interpose a layer of sand

page_text: between the flame and that portion of the bottom of the chamber i with
which the air passing into the room comes in contact; by this means the
temperature of the bottom of the chamber i is prevented from becoming so
high as to communicate an odour to the heated air passing into the room.
The layer of sand n may be applied to the stove, Figure 1. The temperature
of the interior of the chambers b, Figure 1, and i, Figure 2, is sufficiently high
for cooking purposes, and the said chambers may be converted into cooking
ovens by having doors on their sides opening into the room. When I use
the said chambers for cooking purposes, I close the tops of the said chambers
with a flat, unperforated plate on which saucepans or other vessels may be
kept at a boiling temperature.
When there is no objection to the passage of the products of combustion
into the apartment to be heated, I construct the stove in the manner repre-
sented in vertical section in Figure 3, that is to say, I cause the flame of gas
mixed with air to pass up the funnel-shaped flue o. The said flue opens into
the chamber p, constituting the body of the stove.
ment, together with the flame and heated air from the burner, enter and mix
in the said chamber p. The heated air passes through the chamber p into
the apartment by means of perforations at q.
Air from the apart-
Figures 4, 5, and 6 illustrate that part of my Invention which consists in
the application of gas stoves to the ventilation of buildings. I place a box or
chamber on the roof of the building, the angle of the roof being seen at s;
the said chamber is covered by a cap t and cowl u. A series of burners v,
shewn in plan in Figure 5, are situated at or near the lower part of the
chamber r. The said burners may be raised or lowered by the stem w, which
carries them, sliding in the cross piece a, secured to the bottom of the chamber
9. Over each of the burners a funnel-shaped flue, of the form represented in
Figure 6, is situated; the bottoms of the said flues opening into the building,
and the tops of the said flues opening into the chamber r. The flame and
heated air from the burners v pass up the funnel-shaped flues and out at the
cowl u; a current of air through the building also passes up the fluos. By
raising or lowering the burners v, a greater or less quantity of air may be
made to ascend the flues, and a greater or less ventilation of the building is
effected.
Having now described the nature of my said Invention, and the manner of
carrying the same into effect, I wish it to be understood that I do not limit
myself to the precise details herein described and represented, as the same
may be varied without departing from the nature of my said Invention; but
I claim as my Invention,―

page_text: Firstly, the improvements in gas stoves, herein-before described, and
illustrated in Figures 1 and 2 of the accompanying Drawing, that is to say,
the application of the flame of a mixture of gas and air to the heating of a
chamber situated in the interior of the body of the stove, the said chamber being
supplied with air either from the apartment in which the stove is used, or from
the atmosphere external to the said apartment, which said air passes into
the apartment after having been heated by its passage through the said
chamber.
Secondly, the improvements in gas stoves, herein-before described, and
illustrated in Figure 3 of the accompanying Drawing, that is to say, causing
the flame of a mixture of gas and air to enter and heat a funnel-shaped flue
situated in the body of the stove.
Thirdly, the method of applying gas stoves to the ventilation of buildings,
herein-before described, and illustrated in Figures 4, 5, and 6 of the accom-
panying Drawing.
In witness whereof, I, the said Samuel Jabez Goode, have hereunto
set my hand and seal, this Twenty-seventh day of December, in the
year of our Lord One thousand eight hundred and fifty-six.
