BUTTER."
Sealed the 12th December 1878, and dated the 16th October 1873.
PROVISIONAL SPECIFICATION left by the said John Squire Castle
at the Office of the Commissioners of Patents, with his Petition, on
the 16th October 1873.
I, JOHN SQUIRE CASTLE, of Sidcup, in the County of Kent, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF BUTTER," to be as follows:-
:-
This Invention consists in mixing certain well known' and simple
ingredients with butter so as to double the weight thereof without in
any way altering the quality, freshness, or sweetness of the said butter.
The following is an example of the manner I propose to accomplish
the above object :-I take, say, one pound of butter, and having placed
it in one pint of new milk, I add to it the yolk of an egg. These I
beat well up together in a churn.or by any other suitable means. After

page_text: beating or churning for 10 or 15 minutes the weight of the butter will
be found to have doubled, and the new butter to have the sweet, fresh,
and wholesome qualities of the original one.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Squire Castle in the Great Seal Patent
Office on the 16th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SQUIRE CASTLE, of Sidcup, in the County of Kent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Sixteenth day of October, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Squire Castle, Her
special licence that I, the said John Squire Castle, my executors,
administrators, and assigns, or such others as I, the said John
Squire Castle, 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 Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for “ IMPROVEMENTS IN THE MANUFACTURE OF BUTTER," upon the
condition (amongst others) that I, the said John Squire Castle, 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 John Squire Castle, 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 :—
This Invention consists in mixing certain ingredients with butter so
as to considerably increase the quantity thereof without in any way

page_text: altering the quality, and if salt butter be operated upon by this process
it will be rendered equal to fresh butter.
I will now proceed to describe the best method I am acquainted with
for carrying this Invention into practical effect.
Supposing it is required to double the quantity of butter, I take, say,
one pound of either salt or fresh_butter, and add thereto one pint of pure
milk (new milk by preference), to which I also add the yolk of an egg.
I then place the above ingredients in a churn, and after having well
churned the same for a short time the butter is taken out ready for use,
and will be found to have doubled in quantity, and at the same time be
of a very superior quality, even if it has been made with salt butter.
Having now described and set forth the nature and object of my said
Invention for " Improvements in the Manufacturo of Butter," I would
remark in conclusion that I do not intend to limit myself to the precise
proportions above stated, as the same may be varied according to the
quality of butter which it is required to make, but what I claim as my
Invention, and desire to secure by the herein-before in part recited
Letters Patent is, operating upon butter so as to increase its quantity
without in any way injuring its quality, substantially as above described.
In witness whereof, I, the said John Squire Castle, have hereunto
set my hand and seal, this Fifteenth day of April, in the year of
our Lord One thousand eight hundred and seventy-four.
