Year: 1873

page_text: LETTERS PATENT to William M'Donnell and Charles McDonnell,
of the City and County of Limerick, Ireland, for the Invention
of "A NEW OR IMPROVED MODE OF CLEANING OR PURIFYING and SweetenING
BUTTER SCRAPPINGS AND RANCID OR DECAVED BUTTER"
Sealed the 17th March 1874, and dated the 6th October 1873.
PROVISIONAL SPECIFICATION left by the said William McDonnell
and Charles McDonnell at the Office of the Commissioners of
Patents, with their Petition, on the 6th October 1873..
We, WILLIAM M'DONNELL and CHARLES MCDONNELL, of the City
and County of Limerick, Ireland, do hereby declare the nature of the
said Invention for "A New OR IMPROVED MODE OF CLEANING OR PURIFYING
AND SWEETENING BUTTER SCRAPPINGS' AND RANCID OR DECAYED BUTTER," to be
as follows:-
The object of this Invention is to clean and prepare dirty butter or
butter "scrappings" for the market, and also to renovate and recover the
quality of decayed or rancid butter. For this purpose the "scrappings
are first put with some water into a pan and melted, the dirt then sinks

page_text: to the bottom while the butter floats in oil on the top. It is then
drawn off and after being allowed partly to cool it is put, still in a
liquid state, into a churn with some milk or buttermilk and churned. The
result is that the butter after being separated from the milk with which
it at the first coalesces is renovated as to taste, smell, and appearance.
Rancid or decayed butter after being softened to a consistency of cream
is likewise renovated by this process.
Melting butter "scrappings" as aforesaid is not new, but such
melting by itself only removes the dirt whilst it materially injures the
taste, smell, or appearance, but by the aforesaid process of melting and
churning, and as regards rancid butter, softening and churning, alone
as described, the original qualities of butter in its new or fresh state arc
recovered.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said William M'Donnell and Charles McDonnell in
the Great Seal Patent Office on the 4th April 1874.
.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
M'DONNELL and CHARLES MODONNELL, both of the City and County
of Limerick, Ireland, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her:
Letters Patent, bearing date the Sixth 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 successors,
give and grant unto us, the said William McDonnell and Charles
McDonnell, Her special licence that we, the said William McDonnell
and Charles McDonnell, our executors, administrators, and assigns, or
such others as we, the said William McDonnell and Charles McDonnell,
our 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
"A NEW OR IMPROVED MODE OF CLEANING OR PURIFYING and SweETENING BUTTER
"SCRAPPINGS' AND RANCID OR DECAYED BUTTER," upon the condition (amongst

page_text: others) that we, the said William McDonnell and Charles McDonnell,
our executors or administrators, by an instrument in writing under our,
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 we, the said William McDonnell and Charles
McDonnell, do hereby declare the nature of our 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 :—
The object of this Invention is to clean and prepare dirty butter or
butter scrapings or "scrappings", or grease butter for the market, also
to renovate and recover the quality of decayed or rancid butter.
The butter scrapings are first put with or without water into a pan
and melted, the dirt then sinks to the bottom while the butter floats in
oil on the top. The butter is then drawn off and after being strained is
put into a churn with some cream, milk, or buttermilk, and churned, or
it is first allowed to cool partially and is then put, still in a liquid state,
into a churn with some milk or buttermilk and churned. The result
is that the butter after being separated from the milk with which
it at first coalesces is renovated as to taste, smell, and appearance.
Rancid or decayed butter after being softened by washing through. or
with heated milk or water, or by the direct application of heat to a
consistency of cream is likewise renovated by the process before described.
The butter produced as aforesaid from the butter scrappings or from
the rancid butter is then salted and washed for the market in the usual
manner; or the salt might be put into the churn, but we prefer to put
the salt in afterwards.
Melting butter scrapings as aforesaid is not new, but such melting by
itself only removes the dirt while it materially injures the taste, smell,
and appearance, but by our aforesaid process of melting and churning,
and as regards rancid butter of softening and churning alone, as before
described, the original qualities of butter in its new or fresh state are
recovered.
When the quality of the butter or of the butter saranines is some bad ma

page_text: charcoal or fresh earth, or other suitable disinfectants, and in some cases
we add to it such other material or materials as may be found advisable,
for example, when the butter or scrapings have been injured in texturo
and grain by the melting process, which sometimes happens, then we
add oleine obtained from fats such as lard or tallow. By this process we
find also that lard blends very well with butter, so much so in fact that
they appear to become one and the same substance. This mixture of
butter scrapings and lard when treated as aforesaid is applicable for use,
especially by confectioners and others, in making up much pastry we call
it pastirine.
Having thus described the nature of our said Invention, and in what
manner the same is to be performed, we declare that we do not limit
.ourselves to the exact details described, while at the same time it must
be understood that we are aware that the simple melting of butter or of
butter scrapings is not new, but such melting by itself only removes the
dirt while it materially injures the taste, smell, and appearance of the
butter, wo therefore lay no claim to simply the melting of butter or
butter scrapings, but we do claim, the melting or softening of butter or
of butter scrappings or scrapings with or without the admixture or
addition thereto of disinfectants or other material or materials in com-
bination with the subsequent churning of same in a churn with milk,
cream, or buttermilk, substantially in manner and for the purposes
described.
