IMPROVEMENTS IN GRATES OR STOVES FOR THE HEATING OF AIB, AND GATOTTA CIA an Theme AND ECONOMISING THE CONSUMPTION OF FUEL
Year: 1873

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey,
both of Frome Selwood, in the County of Somerset, for the Inven-
tion of "IMPROVEMENTS IN GRATES OR STOVES FOR THE HEATING OF AIB,
AND GATOTTA CIA an Theme "
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 27th March 1873.
We, HENRY COCKEY, and FRANCIS CHRISTOPHER COCKEY, both of
Frome Selwood, in the County of Somerset, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN GRATES OR STOVES FOR
THE HEATING OF AIR, AND ECONOMISING THE CONSUMPTION OF FUEL,” to be as
follows:-
This Invention has for its objects, firstly, the utilization of what would
but for the use of the apparatus to be described be the waste heat which
usually passes up the chimney; and, secondly, the economising of fuel as

page_text: by the use of the improved stove, grate, or appliance a less quantity of
fuel would be necessary to heat an apartment of a given size.
The improved stove or grate consists in forming at its back either
connected to it or separate a cast-iron box or chamber, into or near the
bottom of which is inserted one end of each of two or more or less tubes,
while the other ends are passed through the fire just over the bottom of
the grate, and terminate a little in advance of the front bars. At or
near the top of the chamber before mentioned is another pipe or pipes
which are made to pass up the back of the fire-place bend forward and
terminate just below and in advance of the top of the fire-place.
By the use of the foregoing the fire not only radiates heat into the
room, but induces a current of air to enter the bottom pipes. This air
becomes heated in its passage, and is discharged into the room from the
upper pipe, producing a continual circulation of air and diffusion of heat
throughout the apartment.
Stoves may be constructed specially adapted for the use of the
apparatus described, but one of the chief features of these improvements
is that the pipes and chamber may be made separate and applied to any
existing grate, and placed in it fit for use without alteration of the
grate; and in the same way the apparatus may be taken out for repairs,
leaving the grate fit for use the same as before it was put in.
The apparatus is not necessarily confined to the exact form described
above, as it may be constructed of a pipe or pipes, without a box, placed
in the grate in such a position that the air will pass in at the lower end
of the pipes, and out at the upper end into the room.
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said Henry
Cockey and Francis Christopher Cockey in the Great Seal Patent
Office on the 10th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY 30
COCKEY, and FRANCIS CHRISOPHER COCKEY, both of Frome Selwood, in
the County of Somerset, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of March, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Henry Cockey and Francis Ohristopher
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 "IM-
PROVEMENTS IN GRATES OR STOVES FOR THE HEATING OF AIR, AND ECONOMISING THE
CONSUMPTION OF FUEL," 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 on or before the Fourteenth day of October
One thousand eight hundred and seventy-three.
NOW KNOW YE, that we, the said Henry Cockey and Francis
Christopher Cockey, do hereby declare the nature of our said Invention,
3 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 for its objects, firstly, the utilization of what would
> but for the use of the apparatus to be described be the waste heat which
usually passes up the chimney; and, secondly, the economising of fuel by
the use of the improved stove, grate, or appliance, a less quantity of fuel
being necessary to heat an apartment of a given size.
The improved stove or grate consists in forming at its back either
; connected to it or separate an iron box or chamber, into or near the
bottom of which is inserted one end of each of two or more or less tubes,
while the other ends are passed through the fire just over the bottom of
the grate, and terminate a little in advance of the front bars. At or

page_text: near the top of the chamber before mentioned is another pipe or pipes
which are made to pass up the back of the fire-place, bend forward and
terminate just below and in advance of the top of the fire-place.
By the use of the foregoing the fire not only radiates heat into the
room but induces a current of air to enter the bottom pipes. This air 5
becomes heated in its passage, and is discharged into the room from the
upper pipe, producing a continual circulation of air and diffusion of heat
throughout the apartment.
Stoves may be constructed specially adapted for the use of the
apparatus described, but one of the chief features of these improvements 1
is that the pipes and chamber may be made separate and applied to any
existing grate, and placed in it fit for use without alteration of the
grate; and in the same way the apparatus may be taken out for repairs,
leaving the grate fit for use the same as before it was put in.
The apparatus is not necessarily confined to the exact form described 1
above, as it may be constructed of a pipe or pipes, without a box, placed
in the grate in such a position that the air will pass in at the lower end
of the pipes and out at the upper end into the room.
In order that the foregoing may be more readily understood, Drawings
are attached hereto of which the following is a description :-Fig. 1 is a 2
sectional elevation; and Fig. 2 is a plan of the arrangement.
A, A, represents the lower pipes or inlets for the air, and B, the upper
pipe or outlet for the air after it has been heated in the chamber C, the
pipes being attached in the position shown. D, D, are the grate bars;
E, the top of the fire-place; and F, the mantel piece. The extremities of 2
the pipes at the inlets and outlets although shown as plain may be
shaped or fashioned so as to become ornamental. Similar letters repre-
sent the same parts in both Figs.
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 3
carried into effect, we would observe in conclusion that we do not
confine or restrict ourselves to the precise details or arrangements which
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 a
the Invention secured to us by the herein-before in part recited Letters

page_text: Patent is, the construction of stoves or grates, or heat extracting
appliances to stoves or grates, substantially as herein described.
In witness whereof, I, the said Henry Cockey, have hereunto set
my hand and seal, this Twenty-fifth day of September, in the year
of our Lord One thousand eight hundred and seventy-three.
