IMPROVE- MENTS IN MAKING EXTRACTS FROM ANIMAL AND VEGETABLE SUBSTANCES
Year: 1846

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
REYBURN, of Brown Street, Glasgow, Chemist, send greeting
WHEREAS IIe present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Seventeenth day of June,
in the ninth year of IIe reign, did, for IIerself, Hei heirs and successors,
give and giant unto me, the said Robert Reyburn, Her especial licence, full
power, sole privilege and authority, that I, the said Robert Reyburn, my
exois, adiñois, and assigns, or such others as I, the said Robert Reyburn,
my exois, adiños, 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 "IMPROVE-
MENTS IN MAKING EXTRACTS FROM ANIMAL AND VEGETABLE SUBSTANCES," in
which said Letters Patent is contained a proviso, that I, the said Robert
Rey buin, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, by an instrument in
writing under my hand and seal, 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.

page_text: my Invention. Figure 2 shows a perspective view of the apparatus partly in
section, so that the nature of the interior may be seen. This apparatus consists
of the chamber A, constructed of wood or other suitable material, having
several doors F, F, through which the animal or vegetable matter to be acted
on is to bo introduced. G is the bottom of the chamber A, in which are
openings to allow the extract to flow through into the lower compartment K,
of the apparatus. E is a pump for pumping the extract from K into the
evaporating pan C, which it will be seen is at the top of the chamber A, hence
the steam which is introduced by the-pipe -D under-the pan-C.into the. space
I will heat the pan and evaporate or concentrate the extract, and it is tho
placing a pan over a chamber A, containing the matter from which an extract
is to be obtained, which constitutes the peculiar character of this Invention.
The animal or vegetable matter having been charged into the chamber A in
such manner as to leave a space I between it and the bottom of the evapo-
rating pan into which steam is to be allowed to flow, the consequence will be
that the steam and water of condensation will pass amongst the vegetable or
animal matter in the chamber A, and produce an extract, which being pumped
up will be concentrated.
Пaving thus described the nature of my Invention, and the manner of
performing the same, I would remark, that the shape and some of the details
may be varied without departing from the peculiar character of my Invention ;
and I would wish it to be understood, that what I claim is, the mode of com-
bining apparatus, as herein described, whereby steam entering into a compart-
ment A, containing the matters to be operated on, is the means of producing
an extract, and of evaporating it when raised into a pan C
In witness whereof, I the said Robert Reyburn, have hereunto set my
hand and seal, this Eighth day of December, in the year of our Lord
One thousand eight hundred and forty-six.
ROBERT (LS) REYBURN.
