5 of Middlesex, do hereby declare the nature of the said Invention for

page_text: The object of this Invention is to manufacture cheap, good, and well-
tasting artificial butter from tallow or other similar fatty materials.
The tallow or other fatty matter is first washed well in cold water and
then cut into pieces and put into a wooden vessel, where it is melted by
steam. A small quantity of acid soda previously dissolved in water is
then added in the proportion of about one per cent. by weight. The
material is then well boiled, and after standing some time a like addition
of soda and boiling is repeated two or three times. The material is then
ultimately boiled in pure water, after which it is sifted through flannel
or other suitable material while still warm. The warm and melted mass
is then ready for being churned in a common or other churn, but under
a temperature of about 50° R.
During the churning about two per cent. of fine oil and about three
to four per cent. of sour milk are added. In the course of about fifteen
minutes the fatty material is changed into butter, which now may be
removed from the churn, well kneaded in cold water, and otherwise
treated as common butter.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Griffith Brewer in the Great Seal Patent
Offico on the 21st August 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD

page_text: 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 "Iи-
PROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL BUTTER," (a communication to
me from abroad by E. Diderichsen, of Copenhagen, in the Kingdom of
Denmark), upon the condition (amongst others) that I, the said Edward
Griffith Brewer, 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 Scal Patent Office within six calendar months next
and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Griffith Brewer, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, that is to say :—
The object of this Invention is to manufacture cheap, good, and well-
tasting artificial butter from tallow or other similar fatty material.
The tallow or other fatty matter is first washed well in cold water and
then cut into pieces and put into a wooden vessel, where it is melted by
steam. A small quantity of acid soda previously dissolved in water is
then added in the proportion of about one per cent. by weight. The
material is then well boiled, and after standing some time a like addition
of soda and boiling is repeated two or three times. The material is then
ultimately boiled in pure water, after which it is sifted through flannel
or other suitable material while still warm. The warm and melted mass
is then ready for being churned in a common or other churn, but under
a temperature of about 50° R.
and about three
In the course of
During the churning about two per cent. of fine oil
to four per cent. of buttermilk or sour milk are added.
about 15 minutes the fatty material is changed into butter, which now
may be removed from the churn, well kneaded in cold water, and
otherwise treated as common butter.
And having thus fully described the nature of this Invention I declare

processes, and by the admixture therewith of soda, oil, and sour milk,
substantially as and for the purpose set forth.
In witness whereof, I, the said Edward Griffith Brewer, have here-
unto set my hand and seal, this Twenty-first day of August, in
