AN IMPROVED METHOD OF COMPOUNDING BY ADMEDICLAY AUDI
Year: 1863

page_text: LETTERS PATENT to Gustave Maillard de Bayelt, of 16, Stamford Street,
in the County of Surrey, Gentleman, and Joseph Emile Vigouléte, of
22, Pitt Srteet, Fitzroy Square, in the County of Middlesex, Analytical
Chemist, for the Invention of "AN IMPROVED METHOD OF COMPOUNDING BY
ADMEDICLAY AUDI "
Sealed the 15th March 1864, and dated the 22nd September 1863.
PROVISIONAL SPECIFICATION left by the said Gustave Maillard de
Bayelt and Joseph Emile Vigouléte at the Office of the Commis-
sioners of Patents, with their Petition, on the 22nd September 1863.
We, GUSTAVE MAILLARD DE BAYELT, of 16, Stamford Street, in the County
of Surrey, Gentleman, and JOSEPH EMILE VIGOULETE, of 22, Pitt Street,
Fitzroy Square, in the County of Middlesex, Analytical Chemist, do hereby
declare the nature of the said Invention for "AN IMPROVED METHOD OF
COMPOUNDING BY AGGLOMERATION ARTIFICIAL FUEL," to be as follows:-
The object of our Invention is to agglomerate coal, coke, charcoal, tan,
sawdust, or other combustible materials into convenient masses for combustion.
For this purpose we either take the dust of such substances, or reduce them to
powder, washing them when necessary to free them from incombustible matters,
and add to them lime and a solution in water of the silicate of soda, potass;
alumina, or any other soluble silicate, with a small portion of the carbonate,
nitrate, or other soluble neutral salt of soda, potash, alumina, or other alkali.
We mix the whole thoroughly in a pug mill or other vessel suitable for mixing,
and then mould it under such pressure as is necessary to make it take the

page_text: shape of the moulds and squeeze out the greater part of the moisture, so that
when taken from the moulds it forms blocks which shortly dry and harden on
exposure. The lime and other materials may be applied to the fuel in various
proportions according to the particular nature of the fuel itself and the
particular sizes and purposes of the agglomerated blocks, but we seldom find it
necessary to apply to every hundred parts (by weight) of the fuel more than 1
to 2 of lime, to 1 of the silicate, and from to of the neutral alkaline
salt
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Gustave Maillard de Bayelt and Joseph Emile Vigouléte
in the Great Seal Patent Office on the 19th March 1864,
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GUSTAVE
MAILLARD DE BAYELT, of 16, Staniford Street, in the County of Surrey, and
JOSEPH EMILE VIGOULETE, of 22, Pitt Street, Fitzroy Square, in the County of
Middlesex, send greeting.
WHEREAS Her most Exceller+ Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of September, in the year of
our Lord One thousand eight hundred and sixty-three, in the twenty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Gustave Maillard de Bayelt and Joseph Emile
Vigoulete, Her special licence that we, the said Gustave Maillard de Bayelt
and Joseph Emile Vigoulete, our executors, administrators, and assigns, or
such others as we, the said Gustave Maillard de Bayelt and Joseph Emile
Vigoulete, our 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 "AN IMPROVED
METHOD OF COMPOUNDING BY AGGLOMERATION ARTIFICIAL FUEL," upon the con-
dition (amongst others) that we, the said Gustave Maillard de Bayelt and
Joseph Emile Vigoulete, our executors or administrators, by an instrument
in writing under our, 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 eause the same to be filed
in the Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letter Patent.

page_text: NOW KNOW YE, that we, the said Gustave Maillard de Bayelt and
Joseph Emile Vigoulete, do hereby declare the nature of our said Invention,
and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The object of our Invention is to agglomerate coal, coke, charcoal, tan,
sawdust, or other combustible materials into convenient masses for combustion.
For this purpose, we either take the dust of such substances, or reduce them
to powder, washing them when necessary to free them from incombustible
matters, and add to them lime and a solution in water of the silicate of soda,
potass, alumina, or any other soluble silicate, with a small portion of the car-
bonate, nitrate, or other soluble neutral salt of soda, potash, alumina, or other
alkali. We mix the all thoroughly in a pug mill or other vessel suitable for
mixing, and then mould it under such pressure as is necessary to make it take
the shape of the moulds and squeeze out the greater part of the moisture, so
that when taken from the moulds it forms blocks which shortly dry and
harden on exposure. The lime and other materials may be applied to the
fuel in various proportions according to the particuiar nature of the fuel itself
and the particular sizes and purposes of the agglomerated blocks, but we
seldom find it necessary to apply to every hundred parts (by weight) of the
fuel, more than 1 to 2 of lime, to 1 of the silicate, and from to of the
neutral alkaline salt. In mixing these substances with the fuel, we prefer to
add first the lime mingled with water to the consistency of milk, and thoroughly
mix it with the fuel, thereby moistening it, we then add to the paste so formed
the other matters above mentioned and again thoroughly mix and mould into
blocks as soon as possible before the chemical action of the substances takes
effect.
In witness whereof, we, the said Gustave Maillard de Bayelt and Joseph
Emile Vigoulete, have hereunto set our hands and seals, this Nine-
teenth day of March, in the year of our Lord One thousand eight
hundred and sixty-four.
