Year: 1857

page_text: LETTERS PATENT to Samuel Campbell, of Newington, in the County
of Surrey, Vegetable Preserver, for the Invention of IMPROVEMENTS IN
PRESERVING VEGETABLE SUBSTANCES."
Sealed the 9th June 1857, and dated the 19th March 1857.
PROVISIONAL SPECIFICATION left by the said Samuel Campbell at the
Office of the Commissioners of Patents, with his Petition, on the 19th
March 1857.
I, SAMUEL CAMPBELL, of Newington, in the County of Surrey, Vegetable
Preserver, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN PRESERVING VEGETABLE SUBSTANCES," to be as follows:-
For preserving potatoes, they are first washed and peeled as for ordinary
use, and then pierced all over, and immediately placed in a solution of salt
and water for 30 minutes, more or less; they are then taken out and put into
a copper containing a solution of pearl barley, and left to siminer gently for a
time. After simmering gently in this solution for about 20 minutes the
potatoes are taken out and allowed to stand about 30 minutes until they are
sufficiently cooled, when they are granulated or broken up into small particles,
and then exposed on shallow trays in a drying room, to a temperature of about
110° Fahrenheit, or otherwise dried; and when sufficiently dried they may be
packed in casks or tins for keeping. Or, the potatoes may be cleaned and
then peeled and cut into slices, and put in the solution of salt and water,
as before mentioned, and afterwards placed in the solution of pearl barley
and allowed to simmer for 7 or S minutes, and then taken out and allowed
to cool, after which they may be removed at once to a drying room, or

page_text: For preserving carrots, onions, cabbages, cauliflowers, turnips, beans, peas,
&c. I use a solution of gum arabic and carbonate of soda. After being
properly cut and prepared they are put into bags and dipped into the solution,
while boiling, for about five minutes, after which they are taken out and
removed to a drying room or apparatus; and when sufficiently dry they may be
packed for keeping.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Samuel Campbell in the Great Seal Patent Office on the
5th August 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
CAMPBELL, of Newington, in the County of Surrey, Vegetable Preserver,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of March, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Samuel Campbell, Her special licence that I, the said Samuel Campbell,
my executors, administrators, and assigns, or such others as I, the said Samuel
Campbell, my 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 Britatn and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN PRESERVING
VEGETABLE SUBSTANCES," upon the condition (amongst others) that I, the said
Samuel Campbell, my executors or administrators, by an instrumentin writing
under my, 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 mouths next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Samuel Campbell, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by thefollowing
statement thereof, that is to say :-
For preserving potatoes, they are first washed and peeled, or washed, boiled,
and peeled as for ordinary use, and then pierced all over and immediately

page_text: placed in a solution of salt and water for thirty minutes, more or less; they
are then taken out and put into a copper containing a solution of pearl barley,
say one quart of bruised pearl barley to ten gallons of water, and left to
simmer. After simmering in this solution for about twenty minutes, the
potatoes are taken out and allowed to stand until they are sufficiently cooled,
when they are granulated or broken up into small particles, and then exposed
on shallow trays in a drying room, to a temperature of about 115° Fahrenheit,
or otherwise dried; and when sufficiently dry they may be packed in casks or
tins for keeping. Or, the potatoes may be cleaned, and then peeled and cut
into slices, and placed in the solution of salt and water, as before mentioned,
and afterwards placed in the solution of pearl barley and allowed to simmer
for seven or eight minutes, and then taken out and allowed to cool, after
which they may be removed at once to a drying room, or apparatus.
For preserving carrots, onions, cabbages, cauliflowers, turnips, beans, peas,
&c. I use a solution of gum arabic and carbonate of soda, in the proportion
of about one quarter of an ounce of carbonate of soda and two ounces of gum
arabic to every gallon of water. After the vegetables have been properly
washed, and such as will admit of it cut into slices or pieces, they are put
into bags and immersed in the solution, while boiling, for about five minutes,
after which they are taken out and removed to a drying room or apparatus ;
and when sufficiently dry they may be packed for keeping.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim, -
First, the employment in the preservation of potatoes of a solution of pearl
barley, in the manuer berein-before described.
Aud, second, the preserving of carrots, onions, cabbages, cauliflowers, tur-
uips, beans, peas, and other like vegetables, by boiling them in a solution of
carbonate of soda and gum arabic preparatory to drying them, as herein-before
described, and then drying them.
In witness whereof, I, the said Samuel Campbell, have hereunto set my
hand and seal, this Thirty-first day of July, One thousand eight
bundred and fifty-seven.
SAMUEL CAMPBELL. (L.S.)
