IMPROVEMENTS IN GAS STOVES
Year: 1873

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey,
both of Frome, in the County of Somerset, for the Invention of
"IMPROVEMENTS IN GAS STOVES."
Sealed the 5th June 1874, and dated the 8th December 1873.
PROVISIONAL SPECIFICATION left by the said Henry Cockey and
Francis Christopher Cockey at the Office of the Commissioners of.
Patents, with their Petition, on the 8th December 1873.
We, HENRY COCKEY and FRANCIS CHRISTOPHER COCKEY, both of
Frome, in the County of Somerset, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN GAS STOVES," to be as follows:-
This Invention has reference to the construction of gas stoves in such
a manner that the products arising from the combustion of the gas may
be carried off without vitiating the atmosphere of the apartment, while
the heat generated may be completely utilized by warming and causing
a circulation of the air in the room in which the stove is placed, and
and
consists in a top and bottom plate, made by preference of cast iron,

page_text: surrounded by a cylinder of sheet iron so as to form a chamber. In the
top and bottom plates a number of circular openings are formed con-
centrically to the general axis. Into these openings tubes extending
from the top to the bottom plate are inserted and fastened thereto, the
tubes being open at both ends so that the air of the room may pass
freely through them. In the centre of the bottom plate an orifice is
made, and within this orifice, or slightly above or below it, is placed a
ring or other suitable burner, to burn either gas alone or by preference
a mixture of gas and air. At or near the middle, or by preference some-
what lower than the middle, and in one side of the outer cylinder one
end of a tube of sufficient capacity to carry off the products of com-
bustion is introduced and closely connected therewith, the other end
being led into an ordinary flue or to the exterior of the building..
The action of the apparatus is as follows:-The gas, or gas and air,
having been lighted at the burner the hot air ascends and heats both
the outer cylinder and the tubes within it; the result is that a current
of cool air from the lower part of the apartment is induced to enter the
tubes from the bottom, and in its passage upwards is heated thereby and
afterwards diffused into the room, while the exterior cylinder also assists
in warming the atmosphere by simple radiation.
It will be seen that the products of combustion do not enter the room
whilst imparting their heat to the tubes and cylinder but escape through
the outlet pipe into the open air or chimney.
The form of the stove although made circular by preference for the
sake of economy is not limited thereto, as it may be made of any suitable
shape, and may be fluted, corrugated, or otherwise fashioned so as to
expose a larger surface to the air and at the same time impart an
ornamental character to the apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Cockey and Francis Christopher Cockey 3
in the Great Seal Patent Office on the 8th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
COCKEY and FRANCIS CHRISTOPHER COCKEY, both of Frome, in the
County of Somerset, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of December, in the year of our Lord
One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Henry Cockey and Francis Christopher Cockey,
Her special licence that we, the said Henry Cockey and Francis
Christopher Cockey, our executors, administrators, and assigns, or such
others as we, the said Henry Cockey and Francis Christopher Cockey,
our 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 GAS STOVES," upon the condition (amongst others)
that we, the said Henry Cockey and Francis Christopher Cockey, our
executors or administrators, by an instrument in writing under our, or
one of our 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 Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Henry Cockey and Francis
Christopher Cockey, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement, reference
being had to the accompanying Drawings, and to the letters and figures
marked thereon, that is to say :-
This Invention has reference to the construction of gas stoves in such
a manner that the products arising from the combustion of the gas may
be carried off without vitiating the atmosphere of the apartment, while
the heat generated may be completely utilized for warming and causing
a circulation of the air in the room in which the stove is placed; and
consists in a top and bottom plate, made by preference of cast iron, and
surrounded by a cylinder of sheet iron so as to form a chamber. In the
top and bottom plates a number of circular openings are formed con-
centrically to the general axis. Into these openings tubes extending
from the top to the bottom plate are inserted and fastened thereto, the
tubes being open at both ends so that the air of the room may pass freely

page_text: through them. In the centre of the bottom plate an orifice is made,
and within this orifice, or slightly above or below it, is placed a ring or
other suitable burner, to burn either gas alone, or by preference a
mixture of gas and air. At or near the middle, or by preference some-
what lower than the middle, and in one side of the outer cylinder one
end of a tube of sufficient capacity to carry off the products of com-
bustion is introduced and closely connected therewith, the other end
being led into an ordinary flue or to the exterior of the building.
In order that the foregoing may be more easily understood Drawings
are attached hereto, of which the following is a description:-
Fig. 1 is a vertical section of the stove; Fig. 2, an elevation; Fig. 3,
a plan at B, B, Fig. 1; and Fig. 4, a section through A, A, Fig. 1.
In Fig. 1 C is the top and D the bottom plate; E is the cylinder of
sheet iron forming the chamber; F, F, F, Fig. 3, are the openings; and
G, G, G, Fig. 1, are the tubes inserted into these openings; H is the
centre orifice; and J, the gas burner; while K is the exit tube for the
products of combustion.
The action of the apparatus is as follows:-The gas, or gas and air,
having been lighted at the burner the hot air ascends and heats both
the outer cylinder and the tubes within it; the result is that a current :
of cool air from the lower part of the apartment is induced to enter the
tubes from the bottom, and in its passage upwards is heated thereby
and afterwards diffused into the room, while the exterior cylinder also
assists in warming the atmosphere by simple radiation.
.
It will be seen that the products of combustion do not enter the room
whilst imparting their heat to the tubes and cylinder, but escape through
the outlet pipe into the open air or chimney.

The form of the stove, although made circular by preference for the
sake of economy, is not limited thereto, as it may be made of any
suitable shape, and may be fluted, corrugated, or otherwise fashioned, so
as to expose a larger surface to the air, and at the same time impart an
ornamental character to the apparatus.
Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that we do not a
confine or restrict ourselves to the precise details or arrangements which

page_text: we have described or referred to, as variations may be made therefrom
without deviating from the principles or main features of this Invention;
but what we consider to be novel and original and therefore claim as the
Invention secured to us by the herein-before in part recited Letters
Patent is, the construction of stoves substantially as herein described
and shown on the Drawings.
In witness whereof, I, the said Henry Cockey, have hereunto set
my hand and seal, this Sixth day of June, in the year of our
Lord One thousand eight hundred and seventy-four.
HENRY COCKEY. (L.S.)
