Year: 1862

page_text: LETTERS PATENT to Jean Baptiste Lavoine, Architect, residing at St.
Pierre, near Calais, Empire of France, for the Invention of "A KITCHEN
RANGE ADAPTED FOR COOKING, WARMING THE APARTMENTS, AND GENERATING
GAS, FOR THE USE OF PRIVATE FAMILIES, HOTELS, OR GENTLEMEN'S COUNTRY
SEATS."
Sealed the 8th May 1863, and dated the 10th November 1862.
PROVISIONAL SPECIFICATION left by the said Jean Baptiste Lavoine
at the Office of the Commissioners of Patents, with his Petition, on
the 10th November 1862.
I, JEAN BAPTISTE LAVOINE, Architect, residing at St. Pierre, near Calais,
Empire of France, do hereby declare the nature of the said Invention for "A
KITCHEN RANGE ADAPTED FOR COOKING, WARMING THE APARTMENTS, AND
GENERATING GAS, FOR THE USE OF PRIVATE FAMILIES, HOTELS, OR GENTLEMEN'S
COUNTRY SEATS," to be as follows:-
The advantages obtained by this Invention are that with a single grate,
consuming a small quantity of coal, I make gas for either lighting or warming
the apartments. By means of the calorifère I warm one or more rooms. The
stove has adapted to it a large boiler, and provisions can be kept warm for
any length of time without altering their properties. It is fitted with one or
more stoves for roasting, and adapted for boiling several articles at the same
time. The stoves for roasting are adapted to be heated either by the fire in
the range or by gas, and the range has the general advantage of consuming

page_text: all the matters which are generally wasted in other stoves. It is in this
quality, and under these denominations, that, on the 21st of January 1861,
I took out a Brevet d'Invention in France for 15 years. Since that time
I have also registered in France, on the 20th of January 1862, an improve-
ment which I had made to this range.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jean Baptiste Lavoine in the Great Seal Patent Office
on the 9th May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BAPTISTE LAVOINE, Architect, residing at St. Pierre, near Calais, Empire of
France, send-greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of November, in the year of our
"Lord One thousand eight hundred and sixty-two, in the twenty-sixth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Jean Baptiste Lavoine, Her special licence, that I, the said
Jean Baptiste Lavoine, my executors, administrators, and assigns, or such
others as I, the said Jean Baptiste Lavoine, 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, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "A KITCHEN RANGE ADAPTED FOR COOKING, WARMING
THE APARTMENTS, AND GENERATING GAS, FOR THE USE OF PRIVATE FAMILIES,
HOTELS, OR GENTLEMEN'S COUNTRY SEATS," upon the condition (amongst others)
that I, the said Jean Baptiste Lavoine, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and seals, 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 Jean Baptiste Lavoine, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:-
.
Up to this time the important localities enjoy alone the benefit of gas

page_text: lighting, through the medium of gazometer, which are established in such
places or towns that can insure to the owners & speculators a dividend
proportionate to the value involved in such establishments, the result of which
is that small places & localities, when they do not afford sufficient profit are
for ever deprived of this mode of ligting, and that out of towns, both private
residing & farms, as well as gentlemen's country seats, have no chance of
being favoured with such an improvement.
To meet this evil, the undersigned has devoted his time & experience in
inventing and combining a gaziferous e caloriferous kitchen range, constructed
on different scales, in order to appropriate the same to the proportions or
importance of each house or mansion. Each model or dimension of this
range will be termed and named by a different Figur or Number, and the
variety of their making and of their interior fittings will meet all the
demands

page_text: moved by the action of the fire-place itself, and regulated by the ventilator B, K.
The inside part of this barrel should be covered with refractory earth quite as
the Dutch oven itself is, and could be opened with a door situated on the
opposite side of which it is adapted to the oven.
By the means of this my Invention I obtain with à same and single fire the
following advantages, in addition to those generally procured by the usual and
common kitchen range:-
opposite side of which it is adapted to the oven.
By the means of this my Invention I obtain with à same and single fire the
following advantages, in addition to those generally procured by the usual and
common kitchen range:-
1° The heating of meals by the known system of bain-marie.
2° The heating of rooms by the medium of calorifères.
3° The gas requisite for lighting.
