IMPROVED ANTI-SCORBUTIC BISCUITS
Year: 1868

page_text: LETTERS PATENT to William Henry Crispin, of Marsh Gate Lane,
Stratford, in the County of Essex, for the Invention of "IMPROVED
ANTI-SCORBUTIC BISCUITS."
Sealed the 24th July 1868, and dated the 28th January 1868.
PROVISIONAL SPECIFICATION left by the said William Henry Crispin
at the Office of the Commissioners of Patents, with his Petition,
on the 28th January 1868.
I, WILLIAM HENRY CRISPIN, of Marsh Gate Lane, Stratford, in the
5 County of Essex, do hereby declare the nature of the said Invention
for "IMPROVED ANTI-SCORBUTIC BISCUITS," to be as follows:-
This Invention consists in the combination and mixture of certain
vegetable substances, which when formed into biscuits constitute

page_text: articles of food which are not only nourishing and palatable, but also
possess valuable anti-scorbutic properties, and are especially useful as
preventatives of sea scurvy. The biscuits are formed by the com-
bination of vegetable substances which contain potash with ordinary
flour, by preference that of wheat. The potato from its chemical com-
position is especially applicable to the purposes of this Invention, but
other vegetable substances which also contain potash may be advan-
tageously employed, either alone or in combination with the potato.
The potatoes or other vegetable substances are taken in a raw or
uncooked state, and having been reduced to a state of fine division
by grating or in any other convenient and suitable manner, are in-
timately mixed with an equal or other desirable proportion by weight
of flour, and formed into biscuits and baked in the ordinary manner,
as well understood by biscuit makers. The moisture contained in the
vegetables themselves will usually be sufficient to secure the necessary
combination between such substances and the flour, but a small quantity
of water or milk may if requisite be added for that purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
-filed by the said William Henry Crispin in the Great Seal Patent
Office on the 28th July 1808.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
HENRY CRISPIN, of Marsh Gate Lane, Stratford, in the County of
Essex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-eighth day of January, 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 William Henry Crispin,
Her special licence that I, the said William Henry Crispin, my execu-
tors, administrators, and assigns, or such others as I, the said William
Henry Crispin, 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

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVED ANTI-SCORBUTIC BISCUITS," upon the condition (amongst
others), that I, the said William Henry Crispin, my executors or
administrators, by an instrument in 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 months next and immediately after
the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Henry Crispin, 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 consists in the combination and mixture of certain
vegetable substances which when formed into biscuits constitute articles
of food which are not only nourishing and palatable, but also possess
valuable anti-scorbutic properties, and are especially useful as pre-
ventives of sea scurvy. The biscuits are formed by the combination
of vegetable substances which contain potash with ordinary flour, by
preference that of wheat. The potato, from its chemical composition,
is especially applicable to the purposes of my said Invention, but other
vegetable substances which also contain potash may be advantageously
employed, either alone or in combination with the potato. The potatoes
or other vegetable substances are taken in a raw or uncooked state, and
having been reduced to a state of fine division by grating, or in any
other convenient and suitable manner, are intimately mixed with an
equal or other desirable proportion by weight of flour, and formed into
biscuits and baked in the ordinary manner, as well understood by biscuit
makers. The moisture contained in the vegetables themselves will
usually be sufficient to secure the necessary combination between such
substances and the flour, but a small quantity of water or milk may if
requisite be added for that purpose.
Having thus declared and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I would observe in
conclusion that what I consider novel and original and therefore claim
as constituting the Invention secured to me by the said herein-before in
part recited Letters Patent is, the method of preparing anti-scorbutic

page_text: biscuits, substantially as herein-before described and set forth, or any
mere modifications thereof.
In witness whereof, I, the said William Henry Crispin, have here-
unto set my hand and seal, this Twenty-eighth day of July, in
the year of our Lord One thousand eight hundred and sixty-
eight.
