John Scott, of the same Place, Overlooker, for the Invention of
"IMPROVEMENTS IN EXTRACTING OR RECOVERING GREASE AND OIL FROM

Sealed the 8th March 1872, and dated the 11th September 1871.
PROVISIONAL SPECIFICATION left by the said Matthew Mirfield and'
John Scott at the Office of the Commissioners of Patents, with
their Petition, on the 11th September 1871.
We, MATTHEW MIRFIELD, of Holme Lane Mills, Tong, near Bradford,
in the County of York, Worsted Top Maker, and JOHN SCOTT, of the
same Place, Overlooker, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN EXTRACTING OR RECOVERING GREASE AND
OIL FROM SOAPSUDS AND SEAK' OR SAPONACEOUS LIQUORS," to be as follows:-
$
This Invention relates to the treatment of soapsuds, "seak," or
saponaceous liquors used in the washing of wool or other fibrous
substances or fabrics, and the improvements consist in the distillation
thereof, either by an ordinary still or a still specially prepared or

page_text: constructed for the purpose, by which we not only recover the grease,
oil, or other saponaceous matters for further use, but the water in which
such were held in solution or contained being evaporated is rendered pure
and soft or free from salts or carthy matters, so as to be better adapted
for the purpose of washing wool or other fibrous substances or fabrics.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Matthew Mirfield and John Scott in the Great
Seal Patent Office on the 11th March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, MATTHEW
MIRFIELD, of Holme Lane Mills, Tong, near Bradford, in the County

Her special licence that we, the said Matthew Mirfield and John
Scott, our executors, administrators, and assigns, or such others as
we, the said Matthew Mirfield and John Scott, our executors, adminis-
trators, 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
EXTRACTING OR RECOVERING GREASE AND OIL FROM SOAPSUDS AND 'SEAK' OR
SAPONACEOUS LIQUORS," upon the condition (amongst others) that we, the
said Matthew Mirfield and John Scott, 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 Matthew Mirfield and John
Scott, do hereby declare the nature of our said Invention, and in what

page_text: 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 relates to the treatment of soapsuds, "seak," or
saponaceous liquors used in the washing of wool or other fibrous sub-
stances or fabrics, and the improvements consist in the distillation thereof,
either by an ordinary still or a still specially prepared or constructed for
the purpose, by which we not only recover the grease, oil, or other
saponaceous matters for further use, but the water in which such were
held in solution or contained being evaporated is rendered pure and soft,
or free from salts or carthy matter, and so better adapted for the
purpose of washing wool or other fibrous substances or fabrics.
Such being the nature and advantages of the said Invention, the
manner in which the same is to be performed will be readily understood
by persons acquainted with ordinary distillation.
Having thus described the nature and particulars of the said Inven-
tion, we desire it to be understood that we claim, the extracting or
recovering grease and oil from soapsuds and "seak" or saponaceous
liquors by distillation thereof.
In witness whereof, we, the said Matthew Mirfield and Jo h
Scott, have hereunto set our hands and seals, this Eighth day
of March, in the year of our Lord One thousand eight hundred
and seventy-two.
