AN IMPROVED APPARATUS FOR COOKING OR PREPARING EDIBLE SUBSTANCES
Year: 1854

page_text: LETTERS PATENT to Edward Loysel, of Rue de Grétry, Paris, in the
Empire of France, Civil Engineer, for the Invention of "AN IMPROVED
APPARATUS FOR COOKING OR PREPARING EDIBLE SUBSTANCES."
Sealed the 22nd June 1855, and dated the 22nd December 1854.
PROVISIONAL SPECIFICATION left by the said Edward Loysel at
the Office of the Commissioners of Patents, with his Petition, on the
22nd December 1854.
I, EDWARD LOYSEL, of Rue de Grétry, Paris, in the Empire of France,
Civil Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED APPARATUS FOR COOKING OR PREPARING EDIBLE SUBSTANCES" to be
as follows:-
This apparatus is intended to roast, bake, or prepare such substances as
require the application of heated air to bring them to such a state as will
render them fit for food, such, for instance, as potatoes, chestnuts, cakes, bread,
&c. The apparatus is also applicable for roasting or preparing coffee, and
consists of two dish-shaped vessels, which are hinged together at one side, and
are provided at the opposite side with handles to hold the parts together.
These vessels are provided internally with perforated false bottoms, upon
which the articles to be operated upon are placed. One of the dish-shaped
vessels acts as a cover for the other when in use, and the two parts are held

page_text: together by means of the handles. A vacant space of a considerable capacity
being thus formed, and the articles to be cooked or roasted placed therein on
one of the perforated false bottoms, the apparatus may be placed on any fire,
and the heat therefrom will quickly heat the metal of which the apparatus is
constructed, and this heat will be communicated to the articles placed therein.
When the articles are cooked to a certain extent on one side, the apparatus
may be turned over; and this operation may be repeated from time to time,
according to the nature of the article, and until the operation is completed.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Loysel in the Great Seal Patent Office on the
22nd June 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
LOYSEL, of Rue de Grétry, Paris, in the Empire of France, Civil Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Edward Loysel, Her special license that I, the said Edward
Loysel, my executors, administrators, and assigns, or such others as I, the
said Edward Loysel, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
excrcise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED
APPARATUS FOR COOKING OR PREPARING EDIBLE SUBSTANCES," upon the con-
dition (amongst others) that I, the said Edward Loysel, by an instrument
in writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Edward Loysel, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following

page_text: statement, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say):-
This improved apparatus for cooking or preparing edible substances is
intended to roast, bake, or prepare such substances as require the application
of heated air to bring them to such a state as will render them fit for food,
such, for instance, as potatoes, chestnuts, cakes, bread, and other analogous
substances. The apparatus is also applicable for roasting or preparing coffee,
and consists of two dish-shaped vessels, which are hinged together at one side,
and are provided at the opposite side with handles to hold the parts together.
These vessels are provided internally with perforated false bottoms, upon which
the articles to be operated upon are placed. One of the dish-shaped vessels
acts as a cover for the other when in use, and the two parts are held together
by means of the handles, a vacant space of a considerable capacity being thus
formed, and the articles to be cooked or roasted placed therein on one of the
perforated false bottoms. The apparatus may be placed on any fire, and
the heat therefrom will quickly heat the metal of which the apparatus is con-
structed, and this heat will be communicated to the articles placed therein.
When the articles are cooked to a certain extent on one side, the apparatus
may be turned over; and this operation may be repeated from time to time,
according to the nature of the article, and until the operation is completed.
In the accompanying Drawing, Fig. 1 is a sectional view of the apparatus
closed, or with the two halves or dish-shaped vessels placed one on the other;
Fig. 2 is a plan view of the inside of the apparatus, shewing the two halves
open. A, A, and B, B, (Fig. 1) are the two dish-shaped vessels or pans,
provided with handles C, C, and hinged together at E. E. The dish-shaped
vessels A, A, and B, B, are provided with perforated false bottoms D, D, which
are temporarily secured to the parts A and B by pins a, a, or in any other
convenient and suitable manner which will admit of their being removed, so
that the inner surfaces of the vessels A and B may be cleaned when required.
If thought desirable the handles C, C, may be made moveable, so that when
not in use, or when travelling, they may be placed inside the vessels A and B,
as shewn by dots in Fig. 2. It is evident that this apparatus, as shewn in the
Drawing, may be used for roasting coffee or chestnuts, or baking bread,
potatoes, onions, carrots, or other roots; and, if desired, one of the dish-shaped
vessels may be made deeper than the other, and the hinge so constructed
that they may be disconnected, so that the shallow vessel may be used as a
frying pan, and the deeper one as a saucepan or kettle.
Having now described my Invention of An Improved Apparatus for Cooking
or Preparing Edible Substances, I claim the apparatus herein shewn and

page_text: described, or any mere modification, in which two dish-shaped vessels are
hinged together and provided with handles, as shewn, so that the apparatus
with the edible substances therein, may be turned over on the fire from time
to time as may be required. I claim also the use of the perforated false
bottoms, either fixed or moveable, when applied for the purposes herein
described.
In witness whereof, I, the said Edward Loysel, have hereunto set my
hand and seal, the Sixteenth day of June, in the year of our Lord
One thousand eight hundred and fifty-five.
EDWARD LOYSEL. (L.S.)
Witness,
