SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
JONES, of Broadmead, Bristol, Baker, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Thirteenth day of March, in the eighth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Henry
Jones, my exors, adiňors, and assigns, Her especial licence, that I, the said
Henry Jones, my exors, adñiors, and assigns, or such others as I, the said
Henry Jones, my exors, admors, or assigns, should at any time agree with, and
no other, from time to time and at all times during the term of years therein.

England, Wales, and the Town of Berwick-upon-Tweed, and in the Islands of
Jersey, Guernsey, Alderney, Sark, and Man, and also in all Her said Majesty's
Colonies and Plantations abroad, my Invention of "A NEW PREPARATION OF
FLOUR FOR CERTAIN PURPOSES;" in which said Letters Patent is contained a
proviso, obliging me, the said Henry Jones, by an instrument in writing under.
said.
my hand and seal, particularly to describe and ascertain the nature of my
Invention, and in what manner the same is to be performed, and to cause the
same to be enrolled 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said.
Henry Jones, do hereby declare the nature of my said Invention to consist in

page_text: .
mixing with the said flour such acids and carbonated alkalies or carbonated
alkaline earths, and sugar, and salt, all in a finely powdered and dry state, as
will, when the flour is made into bread or biscuits, or other the like baked
food, flavor the same and cause the dough to rise as required without the use
of any fermenting matter. And in further compliance with the said proviso,
I, the said Henry Jones, do hereby describe the manner of performing my said
Invention by the following statement theroof, that is to say:-
THE MODE WHICH I ADOPT OF PREPARING THE FLOUR.
I take the wheat or other grain from which the flour to be prepared is made,
of fine quality perfectly dry, or make it so by passing it over a kiln. After
grinding and dressing it, I allow it to remain to ripen for a month or six weeks,
and then in one hundredweight of it, I put ten and a half ounces (avoir-
dupoise) of tartaric acid, finest quality, and as dry as possible, and which has
passed through a very fine sieve; I mix it well with the flour, and pass both
through a flour dressing machine, and allow it to remain untouched for two
or three days that the water of crystallization always more or less present' in
the tartaric acid may be absorbed by the flour, and so form around the particles
of acid a coating of flour that will prevent its immediate contact with the
particles of alkali, and thereby I avoid reducing its power of action; afterwards
I mix with the quantity of flour. an. acid before named, twelve ounces bi-
carbonate of soda in fine powder, twenty-four ounces of muriate of soda, or
.common salt, fine and dry, and eight ounces of loaf sugar in fine powder, and
mix the whole thoroughly together, and then put the whole mixture through a
flour dressing machine, when it will be ready for use. The quantities of acids
and alkalies may have to be slightly varied according to their quality, but the
point to be attained is the neutralization of both; other articles, such as bi-
carbonate of potassa and tartaric or citric acids, will make excellent bread,
but in general they are too expensive. My prepared flour, when used to make
bread, biscuits, or other the like food, only requires to be made into dough
with water in the proportion of ten ounces of water to one pound of flour for
.bread, and about six ounces of water to one pound for biscuits, and baked at
.once in a well-heated oven. But whereas I do not claim as my Invention the
making of my prepared flour into bread, biscuit, or other the like food, but
only the preparation of the flour itself, in manner aforesaid, whereby it will
keep for a long time and be always ready to be made into bread, biscuit, and
other the like food, without the addition of any fermenting matter, and such
my Invention being to the best of my knowledge and belief entirely new and
never before used within that part of Her said Majesty's United Kingdom of

page_text: Great Britain and Ireland called England, Her said Dominion of Wales, or
Town of Berwick-upon-Tweed, or in Her said Majesty's Island of Jersey,
Guernsey, Alderney, Sark, and Man, or in Her said Majesty's Colonies and
Plantations abroad; I do hereby declare this to be my Specification of the
same, and that I do verily believe this my said Specification doth comply in
all respects fully and without reserve or disguise with the proviso in the said
herein-before in part recited Letters Patent contained. Wherefore I hereby
claim to maintain exclusive right and privilege to my said Invention.
In witness whereof the above-named Henry Jones hath hereto set his
hand and seal this Eleventh day of August, in the year of our Lord
One thousand eight hundred and forty-five.
