IMPROVEMENTS IN MILLS FOR GRINDING WHEAT AND OTHER GRAIN
Year: 1853

page_text: LETTERS PATENT to Charles Lowe, of Sheepy Hall, in Sheepy
Magna, in the County of Leicester, Corn Miller, for the Invention
of "IMPROVEMENTS IN MILLS FOR GRINDING WHEAT AND OTHER GRAIN."
Sealed the 7th June 1853, and dated the 14th April 1853.
PROVISIONAL SPECIFICATION left by the said Charles Lowe at
the Office of the Commissioners of Patents, with his Petition, on
the 14th April 1853.
I, CHARLES LOWE, of Sheepy Hall, in Sheepy Magna, in the County
of Leicester, Corn Miller, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MILLS FOR GRINDING WHEAT AND OTHER
GRAIN," to be as follows:-
My improvements have reference to that part of a flour-mill com-
monly called the stone case, and also to the spout or spouts by which
the flour or meal is conveyed away from the stones. It is a well-known
fact that grain in general, but especially when in a damp state, becomes.
more or less heated during the process of grinding, while at the same
time a portion of the water or moisture contained in it is converted
into steam or vapour, which, owing to its specific lightness, does not
readily descend through the spouts, and owing to the centrifugal force

page_text: imparted to it by the runner stone, with which it is in contact, it cannot
escape over the back of the stone, and consequently it condenses and
forms paste in the case and spouts, thereby causing considerable loss
and inconvenience.
It will be seen by referring to the accompanying drawing, that
my invention consists, first, in the use of a skeleton and ventilating
case A, or other framework surrounding the stones, covered with
cloth, wire, gauze, or any other substance that will retain the flour,
and allow the heated air and moisture to escape through it. And,
secondly, in forming the sides and covers of the flour or meal spouts
B, B, in a similar manner, and covering them with the same or any
other substances that will effect the separation of the heated air and
moisture from the flour or meal.
Having now described my said improvements in mills for grinding
wheat and other grain, and the manner of performing the same, I
declare that what I claim as my Invention is the formation of the stone
case and spouts of cloth, wire, gauze, or any other similar substance,
that will allow the heated air and vapour to pass through it away from
the flour without the use of air-blasts, exhausts, or similar artificial
means.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Lowe, in the Great Seal Patent Office,
on the 17th September 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
Charles Lowe, of Sheepy Hall, in Sheepy Magna, in the County of
Leicester, Corn Miller, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Fourteenth day of April, in the year of
our Lord One thousand eight hundred and fifty-three, in the sixteenth
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said Charles Lowe, Her special licence that I, the
said Charles Lowe, my executors, administrators, and assigns, or such
others as I, the said Charles Lowe, my executors, administrators, and

page_text: 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 MILLS FOR GRINDING
WHEAT AND OTHER GRAIN," upon the condition (amongst others) that I,
the said Charles Lowe, by an instrument in writing under my hand
and seal, 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 Charles Lowe, 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):
My improvements have reference to that part of a flour-mill com-
monly called the stone case, and also to the spout or spouts by which
the flour or meal is conveyed away from the stones. I use a spout
marked C, on the top of the case, to aid the escape of the heated air.
It is a well-known fact that grain in general, but especially when in a
damp state, becomes more or less heated during the process of grinding,
while at the same time a portion of the water or moisture contained in
it is converted into steam or vapour, which, owing to its specific light-
ness, does not readily descend through the spouts, and owing to the
centrifugal force imparted to it by the runner stone, with which it is
in contact, it cannot escape over the back of the stone, and conse-
quently it condenses and forms paste in the case and spouts, thereby
causing considerable loss and inconvenience. It will be seen by
referring to the accompanying drawing, that my Invention consists,
first, in the use of a skeleton and ventilating case A, or other frame-
work surrounding the stones, covered with cloth, wire, gauze, bolting
cloth, horsehair, or any other substance that will retain the flour and
allow the heated air and moisture to escape through it. And, secondly,
in forming the sides and covers of the flour or meal spouts B, B, in a

page_text: similar manner, and covering them with the same or any other sub..
stances that will effect the separation of the heated air and moisture
from the flour or meal.
Having now described my said improvements in mills for grinding
wheat and other grain, and the manner of performing the same, I
declare that what I claim as my Invention is the formation of the stone
case and spouts of cloth, wire, gauze, or any other similar substance
that will allow the heated air and vapour to pass through it away from
the flour, either in ordinary mills, or in mills in which air-blasts,
exhausts, or similar artificial means are used.
In witness whereof, I, the said Charles Lowe, have heretofore set
my hand and seal, this Thirteenth day of September, in the
year of our Lord One thousand eight hundred and fifty-three.
