"CERTAIN IMPROVEMENTS IN EXTRACTING COLORING MATTER FROM VEGETABLE,
ANIMAL, AND OTHER SUBSTANCES, AND MAKING DECOCTIONS AND INFUSIONS,
THEREFROM."
Sealed the 23rd April 1861, and dated the 27th October 1860.
PROVISIONAL SPECIFICATION left by the said Joseph Burch and Edward.
Booth at the Office of the Commissioners of Patents, with their Petition,.
on the 27th October 1860.
We, JOSEPH BURCH, of Crag, near Macclesfield, in the County of Chester,
Engineer, and EDWARD BOOTH, of the City of Manchester, in the County of
Lancaster, Manufacturer, do hereby declare the nature of the said Invention
for "CERTAIN IMPROVEMENTS IN EXTRACTING COLORING. MATTER FROM VEGITABLE,.
ANIMAL, AND OTHER SUBSTANCES, AND MAKING DECOCTIONS AND INFUSIONS THERE-
PROM," to be as follows:-
Our Invention consists in the use of apparatus fitted with separate compart-
ments or vessels for containing the material, from whence the essence or
coloring matter is to be extracted, and actuating the same by mechanical
means, in order to keep up a constant dipping of such compartments or vessels
into boiling or heated water or other liquids. The sides of the vessels or

page_text: compartments containing the vegetable or animal material are finely perforated
or partially made of wire gauze, thus making a kind of sieve through which
the heated liquor runs on to the material when the vessels or compartments
are submerged, and through which it drains out when the compartments or
vessels are lifted above the surfaces of the boiling or heated liquid, the process
being a constant alternate dipping and withdrawing of the vessels or compart-
ments, and saturating and draining of the material, and by the action of the
apparatus shifting and turning the material in the compartments or vessels,
until it has completely given out and parted with its essence or coloring
matter.
Our Invention also consists in the use of a press, into which the material is
afterwards thrown for the purpose of abstracting by pressure after it has parted
with its coloring or other property, all the remaining liquor that will drain
therefrom.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed by
the said Joseph Burch and Edward Booth in the Great Seal Patent
Office on the 27th April 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
BURCH, of Crag, near Macclesfield, in the County of Chester, Engineer, and
EDWARD BOOTH, of the City of Manchester, in the County of Lancaster,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-seventh day of October, in the year of our
Lord One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Joseph Burch and Edward Booth, Her especial license that we, the said
Joseph Burch and Edward Booth, our executors, administrators, and assigns,
or such others as we, the said Joseph Burch and Edward Booth, 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 "CERTAIN IMPROVEMENTS IN
EXTRACTING COLORING MATTER FROM VEGETABLE, ANIMAL, AND OTHER SUBSTANCES,
AND MAKING DECOCTIONS AND INFUSIONS THEREFROM," upon the conditions (amongst
.others) that we, the said Joseph Burch and Edward Booth, by an instru-

page_text: ment in writing under our 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 Joseph Burch and Edward Booth,
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 and accompanying Drawings, upon which three
modifications of our Invention are exhibited, that is to say:-
The first modification is shewn on Sheet 1, by Figures 1, 2, and 3.
The second modification is shewn on Sheet 2, by Figures 4, 5, and 5".
And the third modification is shewn on Sheet 3, by Figures 6 and 7; these
modifications we call our "Patent Extracting Apparatus."
We will now describe the first modification. (a) is the outer case of
the steam-boiling apparatus; it may be made of wrought or cast iron,
wood, or other suitable material; it is so constructed that when the insido
bottom lining (b) is fitted therein, a steam chamber (c) is formed for the
purpose of heating or boiling the liquor (d) which it contains, the bottoni
inside lining should be made of copper or such suitable material that no
injurious chemical or other effects can arise therefrom by combination with the
coloring and other matters under extraction; glazed iron will answer for some
purposes, and simply iron in others, as in the process of brewing; (e) is a cock
for letting in and regulating the supply of steam; (f) is a syphon for letting
off the condensed water; (g) is a vacuum valve; the material (h) from which
the colouring matter, essence, or flavour is to be extracted is placed in the
compartments (i), which are formed round the large wheel or cylinder (j) a
due proportion in each; the sides of the compartments should be made of
finely perforated sheet metal, or of wire gauze, for the purpose of allowing the
boiling liquor (d) to run in, when, as the cylinder revolves, the compartments
are being submerged, and to run out when they are raised on the other side
above the liquid level, also to act as a sieve to prevent the escape of the
material; each compartment is provided with a well fitting door or lid (1),
through which the material is thrown in or withdrawn after the operation is
completed; (m) is the axis on which the cylinder revolves, it should, in order
to prevent leakage, be above the liquid level; (n) is a platform upon which
the exhausted material is drawn out of the compartments, to be afterwards
thrown into an ordinary box press, where, under pressure, it parts with the
remainder of the liquor which has not drained out; (o) is a platform on the

page_text: opposite side where the compartments are fed with the material from a trough,
or by other convenient means; when the cylinder is in motion, the material is
completely rolled over each revolution, every particle thereof being thereby shifted
and exposed to the liquid, no settlement can take place, neither, as the cylinder
is always in motion, can any burning at the bottom occur. The constant action of
the liquor running in and draining out of the compartments effectually keeps
the fine perforations clear and open, and quickly draws the colouring matter or
essence out of the material under process; when a cover (k) is required, the
use of which greatly economises heat and hastens the process, it is either fitted
in halves by hinges at the ends, or is suspended over, as shewn in Figures 2
and 5, ready to be lowered to its place when the machine is charged with fresh
material, and the operation is about to commence. Figure 2, 5, and 7, also
shew the running in and out of the liquid or dipping and draining of the
material through the perforated sides of the compartments, cylinders or vessels;
the heating may either be effected by steam or fire, we prefer steam; the
apparatus is made to revolve slowly by various mechanical means; we use
a strap pulley placed upon a shaft upon which a worm is fixed to work into
the worm wheel, which is fixed on the axis of the cylinder, as shewn in
Figures 1 and 4.
The second modification of our Invention is exhibited by Figures 4, 5, and 5a;
this modification differs from the first in the mode of fitting up the compart-
ments for containing the material, which are a series of finely perforated
cylindrical tubes (9); these are fitted parallel with each other round a circular
frame or wheel, which like the first modification revolves upon an axis. Each
cylindrical tube is fitted at one end with a well fitting door, through which the
material is thrown in or loaded, and after the process withdrawn or discharged.
Figure 4 shews an elevation, and Figure 5 a section, and Figure 5ª a plan.
The third modification of our Invention is exhibited by the Figures 6 and 7.
(r) is a fixed pedestal; (s) is a triple forked lever, its fulcrum is jointed to the
top of the pedestal; two finely perforated vessels (t, t,) are suspended from the
major beam of the lever, one at each end; these vessels, by the action of the
crank wheel (v) which by means of the connecting rod (a) actuates the vertical
spur of the lever are alternately made to descend into the boilers (y, y,) thereby
producing the same dipping and draining effect as the revolving compartments
and cylindrical tubes already described, when the perforated vessels which
contain the material are made without well fitting covers, of course in order to
prevent its escape they must not be submerged, but if so fitted with lids, they
may be forced below the surface of the liquor. This modification has one
advantage over the others, namely, the coloring matter or essence may be

page_text: extracted from different descriptions of material at the same time as shewn by
the Figure 7 in the Drawing.
Other modifications might be shewn and described involving the working of
the dipping and draining principle; but having already shown three, we
presume it is not incumbent on us herein to explain and set them forth.
Having now described the peculiar nature of our Invention, and the manner
and effect of its operation, we wish it to be understood that we do not confine
our claims to the three modifications herein set forth and described, so long as
the principle of our Invention be retained, neither do we confine ourselves to
any particular form, material, or dimensions; what we believe to be new and
claim as our Invention, is as follows:-
First, we claim the modes of constructing "extracting apparatus," contain-
ing the general combination of parts herein shewn and set forth, and of
working the same in the manner and for such like purposes as we have
described.
Secondly, we claim for the mode of constructing and using a cylinder or
wheel fitted round with a series of separate perforated compartments, and of
actuating the same, after the manner and for such like purposes as we have
herein described and called the first modification of our Invention.
Thirdly, we claim for the mode of constructing a frame or wheel fitted round
with a series of cylinders, and for using and actuating the same, after the
manner and for such like purposes as we have. herein described and styled the
second modification of our Invention.
Fourthly, we claim the mode of constructing, actuating, and using an
extracting apparatus, containing the same combination of parts, or parts
equivalent thereto, after the manner and for such like purposes as we have
herein described, set forth, and styled the third modification of our Invention.
Fifthly, we claim for the mode, by means of pressure, of driving out of
spent material all the liquor it contains after it has been through the process of
extraction which we have described.
In witness whereof, we the said Joseph Burch and Edward Booth have
hereunto set our hands and seals, this Twenty-sixth day of April, in the
year of our Lord One thousand and sixty-one.
