BROOKES, of Birmingham, in the County of Warwick, Manufacturer, and
WILLIAM LUTWYCHE JONES, of Birmingham aforesaid, Manufacturer, send
grecting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twenty-fourth day of
May, One thousand eight hundred and fifty-two, in the fifteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Isaac Brookes and William Lutwyche Jones, our exors, adñiors, and assigns,
Her especial licence, full power, sole privilege and authority, that we, the said
Isaac Brookes and William Lutwyche Jones, our exors, admors, and assigns,
or such others as wc, the said Isaac Brookes and William Lutwyche Jones,
our exors, admiors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales, and
the Town of Berwick upon Tweed, our Invention of "CERTAIN IMPROVEMENTS IN
STOVES AND OTHER APPARATUS FOR HEATING;" in which said Letters Patent is con-
tained a proviso, that we, the said Isaac Brookes and William Lutwyche Jones,
or one of us, shall cause a particular description of the nature of our said In-
vention, and in what manner the same is to be performed, by an instrument in
writing, under our hands and seals, or under the hand and seal of one of us, to

page_text: be inrolled in Her Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Isaac Brookes and William Lutwyche Jones, do hereby declare that the nature
of our said Invention, and the manner in which the same is to be performed,
are fully described and ascertained in and by the following statement thereof,
reference being had to the Drawing hereunto annexed, and to the letters and
figures marked thereon, that is to say:―
Our Invention consists in constructing stoves in the manner herein-after
particularly described, so that the current of hot air and the gaseous products
of combustion may be made to proceed at pleasure, cither directly to the exit
flue or chimney, or along a series of descending and ascending flues before
proceeding to the exit flue, or be made to proceed partially to the said exit
flue and partially to the said descending and ascending flues, so as to determine
the amount of heat radiated by the said stove. Figure 1 represents a front
elevation of a stove constructed according to our Invention; and Figure 2
represents a side elevation of the same; Figure 3 represents a plan of the
upper part of the said stove; and Figure 4, a plan of the lower part of the
same. a is the body of the stove, in which the fuel is put, and in which com-
bustion takes place; b is a chamber into which the upper part of the body of
the stove opens, and into which the gaseous products of combustion enter;
this chamber is divided into two compartments c, d, by the partition e; at the
back of the said chamber, and immediately opposite the exit flue f, there
is an opening in the division e, which said opening may be closed at pleasure,
either wholly or partially, by the slide or damper g; h, i, j, k, are four
hollow pillars or flues; the upper ends of the flues h, i, open into the
compartment c of the chamber 6, and the upper ends of the flues j, k, open
into the compartment d of the chamber b; the lower ends of the said flues open
into the lower part of the said stove represented in Figure 4; that is to say,
the lower ends of the flues h, j, open into the compartment 1 of Figure 4, and
the ends of the flues i, k, open into the compartment m of the said Figure 4.
The compartment marked n in Figure 4 contains the ash-pit, the opening to
which is marked o in Figure 1. p is a damper in the exit pipe f, by which the
amount of air passing through the stove, and consequently the rate of com-
bustion, may be determined. The action of the several parts of our improved
stove is as follows:-When the slide g is withdrawn from the opening in the
partition e, the heated air from the body of the stove passes directly through

page_text: e
the said opening into the exit flue f, but when the slide g is in the position
represented in Figure 3, the heated air, no longer able to pass directly to the
flue f, descends through the flues j, k, into the lower part of the stove, Figure 4,
and crossing the compartments l, m, ascends through the flues h, i, and arrives
at the compartment c, Figure 3, of the upper part of the stove, from whence
it passes into the exit flue f. By partially closing the opening in the partition
by the slide 9, part of the heated air may be made to pass directly to the
exit flue, and part made to circulate in the vertical flues h, i, j, k, and the
amount of heat radiated by the said flues determined at pleasure. We some-
times place a vessel of water in the ornamental head 9 of the stove. By the
evaporation of the said water the air of the room in which the said stove is
situated is maintained in a proper state of moisture, and the offensive odour
commonly attendant on stoves diminished. Figures 5, 6, and 7 illustrate the
application of our Invention to stoves of a cylindrical or columnar form.
Figure 5 represents a front elevation; Figure 6, a vertical section; and Figure
7, a plan of the upper part of a stove of a columnar form constructed according
to our Invention. is the fire-place; and s, the body of the stove; t is a
chamber at the top of the stove, divided as shewn in Figure 7; and u is a
chamber at the bottom of the stove, in which there is no division, but which
contains the ash-pit v; wis a door in the top chamber, which may be opened
and closed by the rod a; the said door is situated opposite to the exit flue y,
and when by the drawing out of the rod a, the said door is opened, the heated
air passes directly into the exit flue y; when, by the pushing in of the rod a,
the door w is closed, the heated air passes down the flues z, z¹, into the chamber
u, and rising up the flue 1, passes into the exit flue y. By the partial opening
of the door w the heated air may be made partially to pass directly to the exit
Y, and partially to circulate through the flues, 1, 11.
flue
Although we have described and represented our Invention as applied to
those stoves, yet we do not confine ourselves thereto, as the arrangement of
chambers and flues is applicable to stoves only partially closed, or to open fire-
places; and as the said applications require no essential modification of the
arrangement of chambers and flues herein described and represented in the
accompanying Drawing, we do not consider it necessary to describe the said
applications.
Having now described the nature of our said Invention, and the manner in
which the same is to be performed, we wish it to be understood that we do not
limit ourselves to the precise methods of carrying our Invention into effect
herein described and represented in the accompanying Drawing, as the same
may be varied without departing from the nature of our said Invention; but

page_text: we claim the general arrangement of chambers, dampers, and flues herein
described and represented in the accompanying Drawing, whereby the heated
air arising from combustion may be made to pass at pleasuro directly to
the exit flue, or wholly or partially through chambers and descending and
ascending flues, before passing to the said exit flue, whether the same be applied
to close stoves, or to open or partially open stoves, or to open fire-places.
In witness whereof, I, the said Isaac Brookes, have hereunto set my
hand and seal, this Twenty-second day of September, in the year of
our Lord One thousand eight hundred and fifty-two.
