page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
GABRIEL Baron DE SUARCE, of Red Lion Square, Middlesex, Colonel in tho
French Service, and WILLIAM PONTIFEX, of Shoe Lane, in the City of London,
Coppersmith, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Eleventh day of February, in the second year of Her reign, did, for
Herself, Her heirs and successors, give and grant unto us, the said Charles
Gabriel Baron de Suarce and William Pontifex, our exors, admors, and
assigns, Her special license, full power, sole privilege and authority, that we,
the said Charles Gabriel Baron de Suarce and William Pontifex, our exors,
aduiors, and assigns, or such others as we or they should appoint or agree
with, and no others, from time to time and at all times during the term of
fourteen years therein expressed, should and lawfully might make, use, exer-
cise, and vend, within that part of Her said Majesty's United Kingdom of
Great Britain and Ireland called England, Our Dominion of Wales, and Town
of Berwick-upon-Tweed, and also in all Her said Majesty's Colonies and
Plantations abroad, our Invention of "A NEW MODE OF OBTAINING DYES,
COLORS, TANNIN, AND ACIDS FROM VEGETABLE SUBSTANCES," in such manner as
we, the said Charles Gabriel Baron de Suarce and William Pontifex, our

page_text: exors, admors, or assigns, in our or their judgment, should deem expedient;
in which said Letters Patent is contained a proviso, obliging us, the said
Charles Gabriel Baron de Suarce and William Pontifex, within the space of
six calendar months, to be computed from the date of the said Letters Patent,
to cause to be inscribed, by writing under our or one of our hands and seals
in Her said Majesty's Chancery, a particular description of the nature of our
said Invention, and in what manner the same is to be performed and carried
into effect, 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, we, the said
Charles Gabriel Baron de Suarcé and William Pontifex, do hereby declare the
nature of our said Invention to consist in obtaining dyes, colours, tannin, and
acids by placing the vegetable matter from which the extract is to be obtained
in a ground or finely subdivided state into a vessel or apparatus, of the kind
herein-after described, and forcing water or other fluids at different tempera-
tures, according to the extract required, through the said matter by a force
pump or other similar power. And in further compliance with the said
proviso, we, the said Charles Gabriel Baron de Suarce and William Pontifex,
do hereby describe the manner in which our said Invention is to be performed
by the following statement thereof, reference being had to the Drawing
annexed that is to say:
In Figure 1, A, A, A, represents a cylindrical vessel, with a false bottom B,
which false bottom should be perforated over its whole surface with holes like
a colander; this false bottom forms a chamber C, D, separate from the
chamber A, A, A. At the end C of the chamber C, D, is received water or
other fluid, as the case may be, from F, which is an ordinary force pump, E
being the feed pipe leading from the reservoir containing the water or other
fluid to be used; G is an air vessel, with a safety valve H, the former to keep
up an equal and constant flow of water or other fluid from the force pump,
and the latter to regulate the amount of pressure given to it; J, J, is a
cross beam or bridge, supported on the brackets K, K, and held in its place
by bolts at S, S. Through this bridge passes the press screw L, turned by
the handle M. This screw acts upon a cover or plate N, which is also per-
forated like a colander, and is placed on the top of the matter from which
the extract is to be obtained.
Figure 2 is a plan of Figure 1. When the
extract is to be made, the following directions should be attended to. For the

page_text: purposes of this explanation, as regards dies and colours, we will suppose
logwood to be the matter to be acted upon, and the logwood dye to be the
extract sought to be obtained. The chambers A, A, A, and C, D, being
perfectly empty and clean, we take out the bolts S, S, and remove the cover N
and screw L, bridge and all; we then take a quantity of ground logwood, or
sawdust made from logwood, and place it in the chamber A, A, A, upon the
false bottom B, packing or pressing it down firmly by the hand till the
chamber A, A, A, is filled to about the height at which the cover N stands,
as shewn in the Drawing; we then replace the cover N, screw L, and. bridge
J, J, putting in the bolts S, S, to keep all firmly to their places; we then, by
means of the screw lever M, give a slight pressure upon the ground logwood
beneath it, and leaving it under that pressure, commence pumping clean
water, raised to a temperature of about 160° Fahrenheit, into the chamber
C, D, by means of the force pump F, which causes the water to rise up
through the ground logwood, and to fill the upper part of the chamber A, A, A,
with logwood die or extract. And as regards tannin and acids, if you place a
Sicily shumack in the chamber A, A, A, and force water through it at a tem-
perature of about 190 degrees of Fahrenheit, tannin and gallic acid will be
produced, mixed with water.
Now, whereas it is evident that dyes or colours, or tannin or acids, may be
made from any suitable vegetable matter placed in an apparatus of this kind
in the finely subdivided state herein-before mentioned, by forcing suitable
liquids through it, in manner aforesaid, at such temperatures as experience may
shew to be best adapted for each particular extract: And whereas the liquid
used may be clean water, or any other more suitable fluid or mixture of fluids,
dependant on the nature of the extract required to be obtained by this pro-
cess: And whereas we claim as our Invention the obtaining of dyes, colors,
tannin, or acids from vegetable substances yielding the same, by placing such
substances in a finely subdivided state in an apparatus, such as is herein-
before describing, and forcing water or other suitable fluids through them at
suitable temperatures as aforesaid. And such our Invention being to the
best of our knowledge and belief entirely new and never before used within
that part of Her said Majesty's United Kingdom of Great Britain and
Ireland called England, Her said Dominion of Wales, and Town of Berwick-
upon-Tweed, nor in any of Her said Majesty's Colonies or Plantations abroad,
we do hereby declare this to be our Specification of the same, and that we do
verily believe this our said Specification doth comply in all respects fully and
without reserve or disguise with the proviso in the said herein-before in part

page_text: recited Letters Patent contained; wherefore we do hereby claim to maintain
exclusive right and privilege to our said Invention.
In witness whereof, we, the said Charles Gabriel Baron de Suarce and
William Pontifex, have hereunto set our hands and seals, this Twelfth
day of June, in the year of our Lord One thousand eight hundred and
Thirty-nine
AND BE IT REMEMBERED, that on the Twelfth day of June, in the
year of our Lord 1839, the aforesaid Charles Gabriel Baron de Suarce came
before our said Lady the Queen in Her Chancery, and acknowledged the
Specification aforesaid, and all and every thing therein contained and specified,
in form above written. And also the Specification aforesaid was stamped
according to the tenor of the Statute made for that purpose.
Inrolled the Thirteenth day of June, in the year of our Lord One
thousand eight hundred and thirty-nine.
