page_text: LETTERS PATENT to George Hayes Carter, of Mottingham Lodge,
near Eltham, in the County of Kent, for the Invention of "Iμ-
PROVEMENTS IN THE CONSTRUCTION OF GAS STOVES, APPLICABLE FOR HEATING
PUBLIC AND PRIVATE BUILDINGS, PINERIES, HOTHOUSES, GRAPERIES, AND SUCH
LIKE BUILDINGS AND PURPOSES."
PROVISIONAL SPECIFICATION left by the said George Hayes Carter
at the Office of the Commissioners of Patents, with his Petition,
on the 4th May 1872.
•
I, GEORGE HAYES CARTER, of Mottingham Lodge, near Eltham, in
the County of Kent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION OF GAS STOVES, APPLICABLE FOR
HEATING PUBLIC AND PRIVATE BUILDINGS, PINERIES, HOTHOUSES, GRAPERIES, AND
SUCH LIKE BUILDINGS AND PURPOSES," to be as follows:-
This Invention consists in constructing, arranging, and operating with
gas stoves in the following manner:-I form a cylinder of sheet:

page_text: metal, say six inches in diameter by about two fect six inches high, the
bottom end of which I mount on fect for the admission of atmospheric
air to the gas burner and the inside of the said cylinder, and within the
aforesaid cylinder for about eight inches more or less from the bottom
end thereof I fix a helical shaped plate or plates with an opening
through the centre. Upon the top of the said helix I arrange and fill
the said cylinder loosely with a quantity of separate strips of thin sheet
metal, each strip being twisted or shaped as a ringlet or curl so as to
expose a large surface for the heated air to act upon, and also to arrest
or check in its passage upwards the too sudden escape of the heat, and
by these means to cause the heated air and gases to be superheated, and
thus to give off a moist heat without offensive smell after the stove has
been heated a few minutes. By thus constructing gas stoves suitable
for heating I am enabled with a single argand or fish tail gas burner
to obtain and give off a large amount of heat at a very small cost.
And I would here remark that for greenhouses, hothouses, and such
like places I propose to surround the said cylinder with a jacket
containing water and lead therefrom pipes for the circulation of the
heated water after the well known manner of heating with hot water.
I also connect a pipe to the top of the said stove for the passage of
the heated air and gases so as to obtain and present a large amount of
heating surface within the house.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by tho said George Hayes Carter in the Great Seal Patent
Office on the 4th November 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HAYES CARTER, of Mottingham Lodge, near Eltham, in the County of
Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of May, in the year of
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Hayes Carter, Her special licence
that I, the said George Hayes Carter, my executors, administrators,

page_text: and assigns, or such others as I, the said George Hayes Carter,. 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 "IMPROVEMENTS IN
THE CONSTRUCTION OF GAS STOVES APPLICABLE FOR HEATING PUBLIC AND PRIVATE
BUILDINGS, PINERIES, HOTHOUSES, GRAPERIES, AND SUCH LIKE BUILDINGS AND
PURPOSES," upon the condition (amongst others) that I, the said George
Hayes Carter, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should 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 Scal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent:
NOW KNOW YE, that I, the said George Hayes Carter, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :—
This Invention consists in constructing, arranging, and operating with
gas stoves in the following manner :-I form a cylinder of sheet metal;
say six inches in diameter by about two feet six inches high, the bottom
end of which I mount on feet for the admission of atmospheric air to
the gas burner and the inside of the said cylinder, and within the afore-
said cylinder for about eight inches more or less from the bottom end
thereof I fix a helical shaped plate or plates with an opening through
the centre. Upon the top of the said helix I arrange and fill the said
cylinder loosely with a quantity of separate strips of thin sheet metal,
each strip being twisted or shaped as a ringlet or curl. so as to expose
a large surface for the heated air to act upon, and also to arrest or check
in its passage upwards the too sudden escape of the heat, and by these
means to cause the heated air and gases to be superheated, and, thus
to give off a moist heat without offensive smell after. the stove has been
heated a few minutes. By thus constructing gas stoves suitable for
heating I am enabled with a single argand or fish-tail gas burner to
obtain and give off a large amount of heat at a very small cost. And
I would here. remark that for greenhouses, hothouses, and such like
places I propose to surround the said cylinder with a jacket containing

page_text: water and lead therefrom pipes for the circulation of the heated water
after the well-known manner of heating with hot water. I also connect
a pipe to the top of the said stove for the passage of the heated air and
gases so as to obtain and present a large amount of heating surface
within the house.
And in order to explain this Invention fully I now proceed to describe
the arrangement and construction thereof by reference to the annexed
Drawing, which shows three views of the said Invention.
DESCRIPTION OF TILE DRAWING.
Figure 1 represents a transverse and vertical section of a greenhouse,
shewing the manner of arranging the gas stove and pipe leading there-
from through the roof of the house and also the pipes for the circulation
of hot water; Figure 2 is a longitudinal and vertical section of Figure 1;
Figure 3 is an enlarged view of a stove without the water jacket for
domestic use. At each of the above Figures similar letters of reference:
are placed upon corresponding parts.
I form a cylinder A as at Figure 2, of sheet metal, in the proportion
of six inches in diameter by about two feet six inches high; the bottom
end of this cylinder I mount on fect a for the admission of atmospheric
air to the gas burner B and heated air to the inside of the said cylinder.
Within the cylinder A. for about eight inches more or less from the
bottom end thereof I fix a helical shaped plate or plates C with an
opening through the centre thereof. Upon the top of the helix C I
arrange and fill the said cylinder loosely with a quantity of separate
strips of thin sheet metal D, cach strip being twisted or shaped as a
ringlet or curl so as to expose a large surface of the heated air to act
upon and also to arrest or check in its passage upwards the too sudden
escape of the heat, and by these means to cause the heated air and
gases to be superheated and thus to give off a moist heat without
offensive smell after the stove has been heated a few minutes. At
Figure 3 E is a wire gauze lid or cover for a stove for domestic use.
By thus constructing gas stoves suitable for heating I am enabled with
a single argand or fish-tail gas burner to obtain and give off a large
amount of heat at a very small cost. And I would here remark that
for greenhouses, hothouses, and such like places I propose to surround
the cylinder A with a jacket F containing water and lead therefrom
pipes G, as shewn at at Figure 2, for the circulation of the heated water
E

page_text: after the well-known manner of heating with hot water. I also connect
a pipe H to the top of the stove for the passage of the heated air and
gases so as to obtain and present a large amount of heating surface
within the house. The Drawing only shews the pipe G of the stove
partially filled with strips of metal D, but I propose if desirable to fill
the whole of the pipes H with strips or any portion of the entire
length of the said pipes according to the degree of heat required to be
given off.
Having now fully described and set forth the nature and object of,
my said Invention for " Improvements in the Construction of Gas
Stoves applicable for Heating Public and Private Buildings, Pinerics,
Hothouses, Graperies, and such like Buildings and Purposes," together
with the means by which it may be effected, I hereby declare my
Invention to consist in, and I claim, adapting twisted, curled, or bent
6 pieces of thin or sheet metal in combination with a helical-shaped plato
or plates within a cylindrical or other shaped case in the construction
of gas stoves as above described with reference to the accompanying
Drawing..
In witness whereof, I, the said George Hayes Carter, havo here-
unto, set my hand and seal, this Second day of November, in
the year of our Lord One thousand cight hundred and seventy-
two.
