IMPROVEMENTS IN THE PREPARATION OF FUEL
Year: 1838

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, STEPHEN
GEARY, of Hamilton Place, New Road, in the County of Middlesex, Architect,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-eighth day of May, in the first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Stephen Geary, Her especial licence, full power, sole privilege and authority,
that I, the said Stephen Geary, my exors, admors, and assigns, or such others
as I, the said Stephen Geary, my exors, adññiors, or assigns, should at any
time agree with, and no others, from time to time and at all times during
the term of years therein expressed, should and lawfully might make, use,
exercise, and vend, within England, Wales, and the Town of Berwick-upon-
Tweed, my Invention of "IMPROVEMENTS IN THE PREPARATION OF FUEL;"
in which said Letters Patent is contained a proviso that I, the said Stephen
Geary, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her
said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in and
by the same, reference being thereunto had, will more fully and at large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Stephen Geary, do hereby declare the nature of my said Invention, and

page_text: the manner in which the same is to be performed, are fully d
ascertained in and by the following statement thereof (that is to s
My Invention relates to a mode of preparing fuel from certain
combustible and other matters as will be hereafter described; and
give the best information in my power, I will in the first place stat
matters which may be employed in preparing fuel according to my
First. Pitch or such like bituminous matters.obtained from
coal tar or from other mineral or vegetable tar, or from
india rubber (caoutchouc)
Secondly. Coal cinders or coke, or powdered peat or bark of
trees pulverized, or sawdust, or tan, such substances
or matters being in a dry state
Thirdly. Clay, dry and coarsely powdered, or, instead of clay,
fine sand may be employed or free stone powdered, or
chalk, or plaster, or earth, or the cinders of wood, or
generally any earthy matter well powdered and dry
Fourthly.-Small of coal
Now I would remark that I am aware that most of these matters have
been before used, or proposed to be used for the purpose of fuel, and they have
been combined together in varied proportions, I do not therefore lay any claim to
the same separately or combined when not according to my Invention as here-
after stated and accurately defined. The above-mentioned materials, or some
of them, are to be blended together, and prepared into a fuel in the following
manner-The pitch or matter named as the first material is to be melted in a
suitable large vessel, and the cinders, or some one or more of the matters
mentioned secondly, are to be gradually introduced amongst the melted pitch;
keeping the matters in the vessel constantly stirred. The clay, or some one
or more of the matters mentioned under the head thirdly, are to be gradually
applied and well stirred into the matters previously in the vessel, heat being
constantly kept up to the matters so being mixed. One half of the small coal
may now be gradually supplied and stirred into the mixture in the vessel, and
stir the matters well together till the whole mixture is equally and well heated,
then pour in the acid, still stirring (I prefer sulphuric acid, that acid being the
cheapest for the purpose, but I do not confine myself thereto, as other acids may be
employed which will produce a like effect), which will produce a froth; and sosoon

page_text: as the effervescence is apparent introduce the remainder of the small coal, stirring
in order to blend the matters equally, and continue the stirring till the whole
becomes well and equally heated, when the mixture may be permitted to run
from the vessel into moulds, which should be of a quadrangular or other figure,
which will produce blocks of a shape to pack closely together when the same
have been well dried. When the matter has been run into the moulds, and
partly cooled, pressure or beating may be applied in order to compress the
blocks into as small a space as possible, but this is not essential, though whero
stowage is material it is desirable that the blocks should each be well beaten
or pressed into the mould.
Having thus explained the nature of the materials employed by me, and the
manner of combining the same, and having been particular in stating quan-
tities of the matters which I have found best to answer the purpose, I would
have it understood that variations may be made without departing from my
Invention, which does not consist in the quantities of the matters employed,
nor is it necessary, in all cases, to use one or more of the matters contained
under secondly and thirdly, in a fuel, though I consider it better to do so. And
I would have it understood that what I claim as my Invention is the mode of
preparing fuel by combining small coal with melted pitch, and with other
matters when in a heated state, and causing the mixture to be acted on by
acid, as above explained, but I do not claim the combining such materials
when an acids is or are not employed.
In witness whereof, I, the said Stephen Geary, have hereunto set
my hand and seal, this Twenty-eighth day of November, One thousand
STEPHEN (L.s.) GEARY.
AND BE IT REMEMBERED, that on the Twenty-eighth day of November,
