TO ALL TO WHOM THESE PRESENTS SHALL COME, 1, BARRODALL
ROBERT DODD, of Change Alley, in the City of London, Civil Engineer, do
send greeting
WHEREAS is most Excellent Majesty King George the Thud, by Ilis
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, beang date at Westminster, the Eighteenth day of April, in the
forty-fifth year of his reign, did give and giant unto me, the said Barodall Robert
Dodd, my executors, administrators, and assigns, Iis special licence, full
power, sole priviledge and authority, that I, the said Baodall Robert Dodd
my executors, administrators, and assigns, 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, my new invented
"VARIOUS IMPROVEMENTS IN THE CONSTRUCTION OF FIRE-PLACES, AND ADAPTING
STOVES AND GRATES THERETO," in which said Letters Patent there is contained
a proviso, obliging me, the said Banodall Robert Dodd, under my hand and
seal, to cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, to be inrolled in His Majesty's
High Court of Chancery within four calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
relation being thereunto had, may more fully and at laige appear
NOW KNOW YE, that in compliance with the said proviso, I, the Bairodall
Robert Dodd, do hereby declare that my Invention is fully desenbed and
ascertained in manner and form following, reference being had to the
Diawings in the margin of these Presents, that is to say

horizontal section of the same immediately below the breast of the chimney,
Figure 3, a side view The same letters refer to the same parts in each
Figure A, columns supporting the chimney; B, the grate; C and D, reflectors
of metal or other suitable materials By the plan, Figure 2. the manner of
constructing the fire-place, the flues, and the situation of the grate is clearly
shewn G and Harc flues of fire-places supposed to be in apartnients below
J and K, plates of iron, of which the sides of the flues in the 100m may be
form'd, from the hearth to the bicast of the chimney, to save an unnecessary
proportion of brickwork in the room L, M, N, O, the throat or opening
of the chimney, which may be contracted at pleasure by plates of iron or
registers, in the usual way, but where a larger aperture may be required it can
be extended, as at P, Q, R, S, and a part thereof at each side, as at F. V, may
be made to lift up at pleasure, in the manner of a register C represents one
of the reflectors pushed back close against the wall, and D, the other half
open
In the Drawing the reflectors are placed close to the grate, but they
should be moveable or made to slide horizontally in grooves on on rolleis vi
otherwise from E to F, which will permit them to open at different angles
and at various distances from the giate, as shewn at W, they may be fixed
on hinges or otherwise vertically to the back of the fire-place, or they may
be united to the sides of the stove or grate, The reflectors may be made
either of one entire piece on separated in the center or elsewhere, as may be
judged to be most convenient, and they might be so constructed as to slide
into a recess formed in the wall, or contrived so as to slide out or turn com-
pleatly round, by which either sile may be presented to the fire, one of which
only might be polished and the other Japanned, in some cases it might be
useful to make the reficctors without either affixing them to the fire-place
on the stove in the manner of a fire screen, to stand upon legs or otherwise,
but there are a variety of modes in which the reflectors might be applied.
The dotted line E A, A E, denotes the space that the brickwork above the
columns forming the chimney projects over.
Brackets or trusses might be
applied to support the chimney, or brickwork instead of columns, if preferred
The principal intention and advantages of these reflectors are to augment the
warmth of the room, with increasing the consumption of the fuel; they may be
used on the first kindling of a fire by being diawn forward at night angles
close to the stove or grate on each side, in which situation they will assist in
producing a strong diaught, and cause the speedy inflammation of the fuel in
the grate; when this is effected they may be pushed about half-way back,
in order that the radiant heat from the sides of the fire may impinge against

page_text: them, and thence be reflected into the 100m but when the fire has burnt clear
or no smoke is apprehended the reflector should be thrown quite back in
which case the duect calorific rays from both sides of the fire will pass into the
room in the same manner as they now do from the front only, and thereby
raise the temperature of the apartment without adding to the consumption of
fuel, and at the same time allow a more extensive view and benefit of the hie
than has been obtained by any other mode Figue 4 is an extinguishei oi
metal case, so formed as to completely inclose the stove or grate with the fe,
which will, when put on, exclude the air, which is so essentially necessary to
combustion, and thereby speedily smother or put out the file without removing
the heated cinders, creating any dust or trouble whatever, and it will also save
the coals in the grate or stove at the time of the extinguishing the fire
In witness whereof. 1, the said Banodal Robert Dodd, have here-
unto set my hand and seal. this Fifteenth day of August, in the
year of our Lord One thousand eight hundred and five
