TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS
JOSEPH FRANÇOIS JULIEN Count de ROBIEN, of East Street, in the Parish of
Saint Mary-le-bone, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-second day of October, in the thirty-fifth year of
His reign, give and grant unto me, the said Louis Joseph François Julien
Count de Robien, His especial licence that I, the said Louis Joseph François
Julien Count de Robien, during the term of years therein mentioned, should
and lawfully might use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "A FIRE-PLACE,
WHICH I CALL THE ECONOMICAL FIRE-PLACE, BY MEANS WHEREOF, AND OF A NEW
METHOD OF DISPOSING OF THE FUEL THEREIN, ONE HALF OF THE FUEL NOW NECESSARY
TO PRODUCE ANY CERTAIN DEGREE OF HEAT WILL BE EFFECTUALLY SAVED, AND IS ALSO
THE MOST CERTAIN MEANS TO PREVENT THE CHIMNEY FROM SMOKING;" in which said
Letters Patent there is contained a proviso obliging me, the said Louis
Joseph François Julien Count de Robien, by an instrument in writing 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 one calendar month after the
date of the said recited Letters Patent, as in and by the same (relation being
thereunto had) may more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Louis Joseph François Julien Count de Robien, do hereby declare that my
said Invention is described in the plan and description thereof hereunto
annexed, and in manner following (that is to say):—
This economical stove is of a circular, cllyptical, or rectangular form. It
stands detached, and is brought forward into the room. It is furnished
with a moveable reflector of a spherical, ellyptical, flat, or cylindrical
form. This reflector has a cover of similar shapes, or even flat. This
stove has a hole in its centre, in which is fixed a hollow channel in a
perpendicular or inclined position, projecting below and above the grate
of the stove; but the upper part of this channel is pierced to admit the air
ascending from below to the fire in the grate. The construction must vary
according to the construction of the chimnies to which it is applied. The
reflector and cover may be suspended by a collar, a pin, or by the supporters,
or by a chain inclining from the reflector. The annexed Drawing and the
explanatory references will be found to answer the above description. The
advantages derived from this stove are the following:-A greater quantity of
heat from the same quantity of fuel used in common stoves, and consequently
a saving in the fuel, as the reflector throws the hent into the room, or upon
the stove itself, if required, as is the case in kitchen ranges or forges, where
the greatest part of the heat is lost in chimnics constructed in the common
manner. In kitchen chimnies, the reflector throwing back upon the stove
the heat (which commonly ascends through the chimney), it surrounds the
vessels placed upon the fire, and accelerates the boiling of micat, vegetables, &c.
In forges the reflector gathers and concentrates the heat upon the metals to be
heated. Heat flues, or pipes for communicating the heat, may also bo
adapted to this economical stove or grate (as will be seen by the annexed
Drawing), and may be used to great advantage. This stove or grato is a
more certain preventive of smoke, as it prevents tho smoke of the adjacent
flues from coming into the room. The cover of the reflector is an additional
means of preventing smoke in caso it should be brought back again by the
cylindric aperture through which it escapes, as it forms a reservoir, where,
mecting with the least resistance, it is carried. Tho vertical channel or fluo
in the middle of the grate causes a more perfect combustion by the freo cir-
culation of air, and by that means diminishes the quantity of smoke. In
short, none of the heat produced by the fire is lost, but all reflected into the
room, upon tlio vessels on the fire, or upon the metals which are heated in a
forge. The Drawings hereunto annexed, and forming part of this my Spcci-
ficution, will serve further to explain the principles of my said Invention, as

page_text: well as to exhibit some of the forms under which it may practically be carried
into effect. But, at the same time, I do hereby assert and claim whatever
privilege or exclusive right and advantago I may by law be entitled to in the
general application of the said principles, and do not confine the application of
the same to any individual or particular construction exclusively, since these
may easily be varied by any ingenious mechanic.
In witness whereof, I, the said Louis Joseph François Julien Count do
Robien, have hereunto set my hand and seal, this Twenty-first day of
November, in the year of our Lord One thousand seven hundred and
ninety-five.
Taken and acknowledged by the above-
named Louis Joseph François Julien
Count de Robien, at the Public
Office in Symond's Inn, this Twenty-
first day of November 1795, before me.

THOMAS MOORE SLADE, Esquire, maketh oath and saith, that he hath asked
Louis Joseph François Julien Count de Robien, who is a Frenchman, and
doth not speak or understand English, in the presence and hearing of John
Simeon, Esquire, Master in Chancery, whether the subscription Le C' do
Robien, and the seal annexed to the Specification of a Patent for a fire-place
now produced, is his hand and seal, and whether the said Instrument contains
the Specification of his Patent Patent which he desires to have inrolled; and
that the said Le Ce do Robien, in answer thereto, doth say, in the presence
and hearing of the said Master, that they are his hand and seal, and that such
Instrument doth contain the Specification of his Patent which he desires to
Sworn at the Public Office in Symond's-
Inn, this 21st day of November
1795, before
T. MOORE SLADE.
