IMPROVEMENTS IN APparatus USED FOR GRINDING CORN OR GRAIN
Year: 1875

page_text: LETTERS PATENT to Lewis Emanuel, of 36, Finsbury Circus, in the
City of London, Solictor and sole Executor of Michael Henry, of
Fleet Chambers, 68, Fleet Street, in the City of London, Patent
Agent, deceased, for the Invention of "IMPROVEMENTS IN APparatus
USED FOR GRINDING CORN OR GRAIN."-A communication to the said
Michael Henry from abroad by Emile Simon Bouchotte, of 17,
Boulevart Saint Martin, Paris, France.
Sealed the 7th September 1875, and dated the 30th March 1875.
PROVISIONAL SPECIFICATION left by the said Michael Henry at the
Office of the Commissioners of Patents, with his Petition, on the
30th March 1875.
I, MICHAEL HENRY, of Flect Chambers, 68, Fleet Street, in the
5 City of London, Patent Agent, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS USED FOR GRINDING CORN
OR GRAIN," communicated to me from abroad by Emile Simon Bouchotte,
of 17, Boulevart Saint Martin, Paris, France, to be as follows:-
In this Invention bolters, sifters, or sieves, are fitted to or combined

page_text: with the runner or running millstone, which is also provided with
channels for the circulation of air disposed over and corresponding with
such sifters or bolters, whereby the bolted or sifted products are duly
moved about, and the runner or running millstone is kept cooled. The
bolting or sifting operation is thus effected on the runner or running
millstone itself, while the latter is at work, and the flour or meal is
discharged as fast as it is bolted or sifted.
The operation is morcover facilitated by the circulation of the air in
the above-mentioned air channels, which lead in a direction from the
centre to the periphery.
In one arrangement for carrying the Invention into effect the air
circulation passages lic between the inner stone and its metal ring, and
the sifters or bolters form the bottom of the same.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Lewis Emanuel in the Great Seal Patent Office on
the 22nd September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LEWIS
EMANUEL, of 36, Finsbury Circus, in the City of London, Solicitor
and sole Exccutor of Michael Henry, of Flect Chambers, 68, Flect
Street, in the City of London, Patent Agent, deceased, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of March, in the year
of our Lord One thousand cight hundred and seventy-five, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Lewis Emanuel, Her special
license that I, the said Lewis Emanuel, my executors, administrators,
and assigns, or such others as I, the said Lewis Emanuel, my exe-
cutors, 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 APPARATUS USED FOR GRINDING CORN OR GRAIN," communicated to the
said Michael Henry from abroad by Emile Simon Bouchotte, of 17,

page_text: )
Boulevart Saint Martin, Paris, France, upon the condition (amongst
others) that I, the said Lewis Emanuel, my executors or adminis-
trators, 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 Lewis Emanuel, 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, reference being had to the accom-
panying Drawings, and to the letters and figures marked thereon, as
communicated to him, that is to say :-
This Invention relates to apparatus used for grinding corn or grain in
which bolters, sifters, or sieves are placed on the runner or running
millstone, which is also provided with a series of channels for circu-
lation of air, such circulation of air helping to displace or move about
the crushed products, and also keeping the millstone cool.
The crushing operation is performed by the runner or running mill-
stone, which makes from 110 to 125 revolutions in a minute, and thus
the flour or other product is discharged as fast as it is bolted or
sifted.
This operation is morcover facilitated by the circulation of the air in
the air channels, which said channels lead in a direction from the centre
to the periphery of the millstone. These air channels are disposed over
and correspond with each bolter or sifter, and take in air at their
mouths or apertures near the eye hole of the stone or opening for the
shaft.
I now proceed, with reference to the accompanying Drawings, to
describe an apparatus constructed according to the Invention.
DESCRIPTION OF THE DRAWINGS.

page_text: A is the annular crown; B, B, are the air channels, the bottoms of
which are formed by the bolters or sifters C, C. These channels B are
cast on the metallic crown of the millstone.
In the plan, Figure 2, the millstone is seen from the top on one side,
and from its under surface on the other side. On the left hand it shews 5
the openings or channels B, B, for the entry of atmospheric air, and on
the right hand the bolters or sifters C, C, are shewn.
Besides the advantages gained and economy resulting from the
employment of this crushing and running millstone, it can be speedily
adapted to any mill without disturbing the ordinary routine of the 1
works, as there is no more trouble in adapting the apparatus than in
replacing a newly dressed millstone.
Having now described the nature of the said Invention, and in what
manner the same may be performed, I declare that I claim,-
First. The improvements in apparatus used for grinding corn or grain 1
in which bolters, sifters, or sieves are arranged and combined with a
runner or running millstone, in the manner and for the purpose
described.
Second. The employment of air channels to runners or running mill-
stones, arranged and combined with bolters, sifters, or sieves in the 2
manner above described and exemplified in the Drawings.
In witness whereof, I, the said Lewis Emanuel, have hereunto
set my hand and seal, this Seventeenth day of September, in
the year One thousand eight hundred and seventy-five.
Witness,
