IMPROVED METHOD OF COMPOUNDING, BY AGGLOMERATION, ARTI- FICIAL FUEL
Year: 1864

page_text: LETTERS PATENT to Gustave Maillard de Bayelt, of 35, Nelson Square,
in the County of Surrey, Gentleman, and Joseph Emile Vigouléte, of
5, Nelson Square, in the County of Surrey, Analytical Chemist, for the
Invention of "IMPROVED METHOD OF COMPOUNDING, BY AGGLOMERATION, ARTI-
FICIAL FUEL."
Sealed the 19th May 1865, and dated the 23rd November 1864.
PROVISIONAL SPECIFICATION left by the said Gustave Maillard de
Bayelt and Joseph Emile Vigouléte at the Office of the Commissioners
of Patents, with their Petition, on the 23rd November 1864.
We, GUSTAVE MAILLARD DE BAYELT, of 35, Nelson Square, in the County
of Surrey, Gentleman, and JOSEPH EMILE VIGOULÉTE, of 5, Nelson Square, in
the County of Surrey, Analytical Chemist, do hereby declare the nature of
the said Invention for "AN IMPROVED METHOD OF COMPOUNDING, BY AGGLOME-
RATION, ARTIFICIAL FUEL," to be as follows:-
The object of our Invention is to agglomerate coal, coke, charcoal, tan,
sawdust, peat, turf, or other combustible substances into convenient masses for
combustion,aud for this purpose we employ a process alreadypartially described
by us in the. Specification of a Patent granted to us, dated the 22nd Sep-
tember 1863; No. 2334, but since the date of the said Patent we have dis-
covered that certain modifications of the process therein described are advan-
tageous, and these modifications form the object of our present Invention.
In the. Specification of the said Patent we have described the use of a

page_text: neutral alkaline salt along with lime and soluble silicates, but we find that in
many cases, not only lime but also carbonates and sulphates of lime may be
employed with the silicates, and that other alkaline salt may be dispensed
with.
We have also described a mode of mixing the ingredients, using lime
mingled with water to the consistency of milk. We now find it in many
cases preferable to mix, first, dry slaked lime or its compounds with the fuel,
dust, or powder, and then to add silicate dissolved in sufficient water to give
the necessary moisture, pressing or moulding the blocks as soon as possible
after the addition of the liquid silicate; or in some cases we find it advan-
tageous to mix not only dry lime or its compounds, but also dry silicate with
the fuel, and to moisten the mixture before moulding.
We also find that when great hardness is required in the agglomerated
fuel, it is advantageous to add a larger proportion of the lime or its com-
pounds, and of the silicates, and sometimes also a small portion of hydro-
fluo-silicic acid, though generally this addition is not essential.
Our process is also applicable to peat or turf, and when we have to operate
on it or other combustible substances in a very moist condition we use
uuslaked lime, which by absorbing much of the moisture renders it quickly
dry and ready for use.
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 23rd May 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we GUSTAVE
MAILLARD DE BAYELT, of 35, Nelson Square, in the County of Surrey, Gentle-
man, and JOSEPH EMILE VIGOULETE, of 5, Nelson Square, in the County of
Surrey, Analytical Chemist, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of November, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth 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 Vigouléte,
Her special licence that we, the said Gustave Maillard de Bayelt and Joseph
Emile Vigouléte, our executors, administrators, and assigns, or such others.
as we, the said Gustave Maillard de Bayeltraud Joseph Emile Vigouléte, our
executors, administrators, and assigns, should at any time agree with, and

page_text: no others, from time to time and at all times thereafter during the term
therein expressed, should aud 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 condition (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 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 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, peat, turf, or other combustible substances into convenient masses
for combustion, and for this purpose we employ a process already partially
described by us in the Specification of a Patent granted to us, dated the
22nd September 1863, No. 2334, but since the date of the said Patent we
have discovered that certain modifications of the process therein described are
advantageous, and these modifications form the objectofour present Invention.
In the Specification of the said Patent we have described the use of a
neutral alkaline salt along with lime and soluble silicates, but we find that in
many cases not only lime, but also carbonates aud sulphates of lime may be
employed with the silicates, and that other alkaline salt may be dispensed
with.
We have also described a mode of mixing the ingredients, using lime
mingled with water to the consistency of milk.
We now find it in many
cases preferable to mix, first, dry slaked lime or its compounds with the fuel,
dust, or powder, and then to add silicate dissolved in sufficient water to give the
necessary moisture, pressing or moulding the blocks as soon as possible after
the addition of the liquid silicate; or in some cases we find it advantageous
to mix not only dry lime or its compounds, but also dry silicate with the fuel,
and to moisten the mixture before moulding.
We also find that when great hardness is required in the agglomerated
fuel, it is advantageous to add a larger proportion of the lime or its com-

page_text: pounds, and of the silicates, and sometimes also a small portion of hydro-fluo-
silicic acid, though generally this addition is not essential.
Our process is also applicable to peat or turf, and when we have to operate
on it or other combustible substances in a very moist condition we use
unslaked lime, which by absorbing much of the moisture renders it quickly
dry and ready for use.
In witness whereof, we, the said Gustave Maillard de Bayelt and Joseph
Emile Vigouléte, have hereunto set our hands and seals, this Twenty-
third day of May, in the year of our Lord One thousand eight hundred
and sixty-five.
