the City of London, Manufacturer, fr
MENTS IN THE MODE OF PREPARING POTAT
of Leadenha Street, in
he Invention of "IMPROVE-
FOR PRESERVATION."
PROVISIONAL SPECIFICATION left by the said Frederick John King
at the Office of the Commissioners of Patents, with his Petition,
on the 5th May 1868.
I, FREDERICK JOHN KING, of Leadenhall Street, in the City of
London, Manufacturer, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN THE MODE OF PREPARING POTATOES FOR PRE-
SERVATION," to be as follows:-
This Invention has reference to a mode of separating the skins from
potatoes intended for further subsequent treatment with a view to
preservation, and consists essentially in forcing the potatoe pulp after
the potatoes have first sufficiently steamed or boiled through a bag or
bags of canvas or hair cloth or other like textile fabric by the aid of
hydraulic or other pressure, such bags being supported when necessary

page_text: by a perforated plate or wirework. By this means I not only effect
considerable economy in the farinaceous edible portion of the potatoe
by diminishing the waste, but obtain a much cleaner product and one
fitted for preservation than when the skins are removed by merely
forcing the potatoe through wirework or perforated metal as heretofore.
The whole of the peel or skin according to the improved process
remains in the bag or bags, and may be removed either by brushing
or washing, whilst the pulp is in the best condition for subsequent
drying.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Frederick John King in the Great Seal Patent
Office on the 5th November 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
JOHN KING, of Leadenhall Street, in the City of London, Manufacturer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of May, in the year of
our Lord One thousand eight hundred and sixty-eight, in the thirty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Frederick John King, Her special license that I,
the said Frederick John King, my executors, administrators, and assigns,
or such others as I, the said Frederick John King, my executors, adminis-
trators, or assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein ex-
pressed, 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 "IMPROVEMENTS IN THE MODE
OF PREPARING POTATOES FOR PRESERVATION," upon the condition (amongst
others) that I, the said Frederick John King, my executors or
administrators, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said In-
vention, 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.

page_text: NOW KNOW YE, that I, the said Frederick John King, 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 the following statement, that is to say :-
My said Invention has reference to a mode of separating the skins
from potatoes intended for further subsequent treatment with a view to
preservation or for immediate consumption, and consists essentially
in forcing the pototoe pulp after the potatoes have been first sufficiently
steamed or boiled through a bag or bags of canvas or hair cloth, or net,
or other like textile fabric by the aid of hydraulic or other pressure,
such straining fabric being supported when necessary by a perforated
plate or wirework.
:
It is obvious that 'my Invention is also applicable to the preparation
of potatoes for domestic or other purposes, in which case the operation
of expressing the pulp of the potatoe may be conveniently carried
out by means of a cheap and simple apparatus somewhat similar to an
ordinary letter copying press. The potatoes being placed in a bag or
not between two plates, the under one being perforated so as to allow
the passage of the potatoe pulp through it; or in lieu of a porforated'
plate wirework may be used, through which the pulp will be expresse
into a vessel or convenient receptacle placed beneath; or the app...
ratus may be composed of a cylinder of tinned plate, enamelled
iron, or other suitable material, with a perforated bottom, and having
a piston or plunger worked by a screw or lever, and fitting moderately
tight therein, into which cylinder the potatoes are to be placed.
By this Invention I not only effect considerable economy in the
farinaceous edible portion of the potatoe by diminishing the waste, but
I obtain a much cleaner product, and one better fitted for preservation
or consumption than when the skins are removed by hand peeling.
The whole of the peel or skin according to my improved process remains
in the bag or bags or pieces of textile fabric, and may be removed
either by brushing or washing whilst the pulp is in the best condition
for subsequent drying and preservation or for immediate domestic use.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the mode

page_text: of separating the peel from potatoes which have been boiled or steamed
by forcing the pulp by the aid of pressure through fabrics which are
of sufficiently close texture to retain the peel, substantially as herein-
before described.
In witness whereof, I, the said Frederick John King, have to this 5
my Specification set my hand and seal, this Fifth day of
November One thousand eight hundred and sixty-eight.
