Year: 1797

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, NICHOLAS
DUBOIS DE CHEMANT, of Frith Street, in the Parish of Saint Ann, Soho,
within the City and Liberty of Westminster, in in the County of Middlesex,
Surgeon Dentist, send greeting.
WHEREAS His present Majesty King George the Third, by His Letters
Patent, bearing date at Westminster, the Fifteenth day of February, now
last past, hath given and granted unto me, the said Nicholas Dubois De
Chemant, my exors, adiñiors, and assigns, special licence, full power, sole
privilege and authority, to make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, during the term of years
therein expressed, my Invention of "A CERTAIN TABLE, WITH A STOVE PLACED
WITHIN THE CENTRE THEREOF, WHEREBY THE COMPANY MAY BE WARMED;" in which
said Letters Patent there is contained a proviso obliging me, the said Nicholas
Dubois De Chemant, 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 next and immediately 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.
NOW KNOW YE, that I, the said Nicholas Dubois De Chemant, in com-
pliance with the said proviso, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be made, is particularly
described and ascertained in the Plan hereunto annexed, and the following
description thereof, that is to say:-
The table is open in the middle. The vacancy can be filled up at pleasure.
The servants go in and out at this opening through a passage made on
purpose, which can be shut when required, and then the table is complete.

page_text: It can be made of different kinds of wood, and divided into three, four,
or many small tables, and may be used together or separate. This
table can be made of any size or form, either square, oval, or round,
&c., &c.
In the opening or centre is to be placed a stove with pipes
to go round the legs of the table on the floor, on which the company may
warm their feet. The heat of this stove is regulated by means of an extin-
guisher, for the purpose of putting out the fire when the apartment becomes
two hot, which may be adapted to any kind of grate or stove now made,
without altering the construction or form of the grate or stove; the extin-
guisher as well as the stove can be made of different metals, of iron, brass, or
copper. The pipes through which the smoke is to pass are not to be per-
ceived, because they may be placed either under the tables or on the floor, as
may be preferred. This stove may be made not to exceed the height of the
table, and a plate of copper or any other metal with a cover may be placed on
it, in which plates or dishes can be warmed. This: stove may be placed on a
floor or on a carpet without danger of fire. The poker, which, by means of
two hooks placed on the two opposite squares, at the,.end, prevents.it,from
falling out of the stove, provided the poker, is turned in, such a manner as to
leave one of the hooks fastened between one of; the bars, of the grate.--All
this is explained by alphabetical letters in the annexed Figures....
First Figure. A round table divided into, four parts, supported on twenty
legs or only four legs,, with three or four claws to each leg.... A represents: each
quarter of the table; B.represents the two flaps which shut the entrance,
which are, fastened to the table by two hinges, and are kept up when they
are shut by two cross pieces of timber which can be moved at pleasure...
Second Figure represents a round table, (supported by a leg with a claw) of
the same size as the opening of the table in Figure the First...
Third Figure represents the floor on which the legs of.the table and the stove.
rest. A represents the place where the legs stand; B represents the stove.;
C represents the pipe, the two branches of which join together at the letter, D
to go into the chimney of the room; E represents the plate, fixed on the stove
whereon the plates and dishes may be put to be warmed, by means of a lid
adapted to it; F, represents the top of the stove; Grepresents the legs of
the table, behind which the pipes..
Figure the Fourth. A represents the ground plan of the stove.
Fifth Figure.-B represents a section of the stove as divided at the, dotted
line of the ground plan at A; C shews the smoke rising from the, fire, and
dividing itself at the top as represented, discharging itself at the bottom of
the stove at D in the,conducting pipes.,
This stove may be made in whatever form is most approved. In the

page_text: annexed ground plan A, Figure the Fourth; it shews a flat front, the other
part totally circular; this plan is best; for two reasons; first; by means of a flat
front a blower might be fixed so as to draw up the fire at first lighting;
or a door-might be more conveniently fixed to inclose the fire at pleasure;
and, secondly, the circular form is best-constructed for the table itself. The
sides of this stove may be made, if approved, perpendicular, it's diameter about
fourteen or fifteen inches. In the internal part is a body four inches less;
terminating at the top as a "dome; in this dome is a hole-about-five or
six inches diameter, through which's. the smoke rises, and, passing down the
sides and back of; the stove; discharges itself: ati néarly: the bottom of the
stove, in whatever direction is most convenient for the conducting pipes. This
internal body is fixed to the externalione by means of a piece of plate, the
whole height in the center oft the back at Evin Figure the Fourth; and at the
two parts at E, connected with the front, the pieces in the centre of the back
and front not only connect them together; but by dividing the smoke make
it pass to the two different channels. intended for its. discharge the. more
readily. The outer body or sides of the stove may be terminated either
flat or domically leaving a space from the inner doom or top of 'about four
inches. The bottom bars of the fire grate are from eight to nine inches from
the floor, and may be made either two, three, or four bars in height.
To prevent the inner body from being burnt, it is necessary to forin a cast-iron
body about the height of the bars, and in which the bars are fixed as at E,
Figure the Fifth. This cast-iron body may be fixed to the inner circular
body by means of two screws, and remains perfectly secure. Under the
bottom of this, grate,may be placed either a grate with a pan projecting,
as represented Figure the Sixth, or a drawer to slide in and out, with slits.or
holes in the front for the air to pass; this drawer will prevent any cinders:or
ashes from falling into the room... Under this: drawer will be a space which may
have a door, and form an ash-pit for whatever may escape the drawera. The
pipes of this stove may be constructed of iron lor, copper, though copper:fromi
the shape is to be preferred. After, passing: under the table in the direction
approved, it connects itself into a pipe of a larger; bore; and. dischargés:itself.
in the chimney. The smaller pipes should be about four or four and a half
inches in diameter; the larger pipe about six inches diameter. *
Figure the Seventh represents, the lid, which is fastened, on the plate in
order to warm what is put there, to be made of iron or copper, brass. or tin.
Eighth Figure represents the extinguisher, which may be made and adapted
to any kind of grate.
Ninth 'Figure represents, an extinguisher with a plate to shut the bottom, of

page_text: the grate. A-represents two handles of iron, which serve to conduct the
plate; B represents an iron bar which serves to draw the plate, whereby the
bottom of the grate in which the coals are placed shuts by means of a handle
.
fixed to the end of it. C represents. two handles.to place the extinguisher.
D represents two rings which serve as leaders to the undermost plate.
Figure the Tenth represents a poker, with the two hooks which hinder it
from falling out of the grate, to be made of iron.
Eleventh and. Twelfth Figures represent a square and an oval table, to
which the stove may be in like manner applied.
In, witness whereof, I, the said Nicholas Dubois De Chemant, have
hereunto set my hand and seal, this Fifteenth day of March, in
the year of our Lord One thousand seven hundred and ninety-
seven, and in the thirty-seventh year of the reign of King George
the Third.
