Year: 1813

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WHITE, of Princes Street, Soho, in the County of Middlesex, Tinman, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Third day of March, in the fifty-third year of His reign, did, for
Himself, His heirs and successors, give and grant unto the said John White
His special licence, that I, the said John White, my exors, admors, and
assigns, or such others as I, the said John White, my exors, admors, or
assigns, should at any time agree with, and no others, from time to time
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend, within that part of the United Kingdom of Great
Britain and Ireland called England, the Dominion of Wales, and Town
of Berwick-upon-Tweed, and also in all the English Colonies and
Planta-
tions abroad, my Invention of "A MACHINE FOR COOKING WITHOUT WOOD OR
COAL;" in which said Letters Patent there is contained a proviso obliging
me, the said John White, by an instrument in writing under my hand
and -seal, particularly to describe and ascertain the nature of my said In-
vention, and in what manner the same is to be performed, and to cause the
same to be inrolled in His Majesty's High Court of Chancery within two
calendar months next and immediately after the date of the said recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, John
White, do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, is described and ascertained
by the Figures drawn in the margin of these Presents, and the following
explanation thereof, that is to say:-
My Invention consists in applying, by means of a certain apparatus and
utensils, the heat produced by a lamp or lamps to the following purposes:-
First, steaming, boiling, broiling, baking, frying, or stewing, butchers' meat,
fowls, puddings, and other dishes.
Secondly, heating or warming rooms, tents, or other places.
And, thirdly, generating steam and creating a power for working small
machinery.
The apparatus for these purposes consist in a boiler made of copper, tin,
or any other metal, or earthenware.
Figure First is the machine complete as in use. A is the body of the boiler
or water vessel, standing on four pillars; B, B, is the chimney to convey heat
to the tea-kettle or other utensil placed on the trivet G; C is the space occu-
pied by the water; D is the lamp under the water vessel A, and the tube
B, B, which I make of tin, copper, or any other metal, with flat wicks, from
two to any number required, in parallel lines, which admits a double current of
air to each wick, to prevent smoke, and burn common fish oil; but I do
not confine myself to this alone, as the Argand lamp may be used. E is the
aperture through which the steam passes from the water vessel A into the
cooking vessel F, F, into which is placed the victuals intended to be dressed;
G is the trivet on which is placed the stew-pan, tea-kettle, or other utensil;
H, H, is an empty chamber in which to place the cooking utensils when out
I is the cover of the cooking vessel, to take off or on at pleasure;
K, K, are doors to shut up the vessels when not in use, after sliding them
under the cooking vessel F, F. I do not confine myself to use square, round,
or any particular shaped vessel, as my boiler or water vessel A will act inde-
"pendently of the cooking vessel, or in unison with that or any other vessel,
of whatever size or shape, being attached to it or separated from it at
pleasure.
of use;
Figure Second is a section of the boiler in its unmounted state. E, E, E, E,
is the space occupied by the water; C, C, is the heat chamber; F, F, is
the chimney which goes over the lamp; B is the aperture for the steam to
pass out; D, D, is a coating of air which surrounds the vessel E, E, E, E,
to prevent the escape of heat. This boiler introduce into tea-urns, coffee-pots,
or any vessel required.

page_text: Figure Third is a machine for heating rooms. A is the lamp; B is the heat
chamber (as described in Figure Second, C, C,) placed inside of the body of
the machine C; D is the chimney to heat the air contained in the dome E;
F is the aperture for the heated air to escape into the room. These machines
may be of various shapes and sizes, and placed in any part of a house, tent,
ship, &c., &c. When I am to cook (see Figure First) I draw out the boiler A,
and nearly fill it with water at the aperture E, I then return it into the door-
way till the pipe at the bottom of the cooking vessel F, F, is inserted into the
aperture E of the boiler, which will then stand about two thirds out of the
doorway, projecting from the vessel F, F, and this is its proper position when
in use. I now draw out the lamp, fill it with oil, cut the cottons even, and
raise them about one eighth of an inch above the tubes. They are then lighted,
and the lamp returned to its place under the boiler A.
is now fixed in the centre of the boiler, and as soon as the water boils I place
the ingredients to be cooked in the cooking vessel F, F, on a grating therein,
under which is a pan to receive the juices from the meat, &c. The cover I is
then put on, and should not be removed during the cooking, which is about
the usual time of boiling. In the mean time I can stew, broil, bake, or fry on
the trivet G at the top of the chimney.

In witness whereof, I, the said John White, have hereunto set my
hand and seal, the Twenty-eighth day of April, in the year of our
