IMPROVED APPARATUS APPLIED TO MILLSTONES FOR GRINDING WHEAT AND OTHER GRAIN
Year: 1866

page_text: LETTERS PATENT to William Edward Gedge, of the Firm of John Gedge
and Son, of No. 11, Wellington Street, Strand, in the County of Mid-
dlesex, Patent Agent, for the Invention of "IMPROVED APPARATUS APPLIED
TO MILLSTONES FOR GRINDING WHEAT AND OTHER GRAIN."-A communication
from abroad by Pierre Baillargeon, of 39, Faubourg St. Martin, Paris,
France.
Sealed the 18th June 1867, and dated the 22nd December 1866.
PROVISIONAL SPECIFICATION left by the said William Edward Gedge at
the Office of the Commissioners of Patents, with his Petition, on the
22nd December 1866.
I, WILLIAM EDWARD GEDGE, of the Firm of John Gedge and Son, of
No. 11, Wellington Street, Strand, in the County of Middlesex, Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVED
APPARATUS APPLIED TO MILLSTONES FOR GRINDING WHEAT AND OTHER GRAIN," a
communication to me from abroad by Pierre Baillargeon, of 39, Faubourg
St. Martin, Paris, France, to be as follows:-
The apparatus, the subject of this Invention, will be best understood by
reference to the annexed Sheet of Drawing forming part of this Provisional
Specification, Figure 1 being an elevation of a pair of millstones with this
improved apparatus applied thereto, and Figure 2 a plan view.

page_text: a, isolating pendant; A, running stone on which are fixed the helicoidal
paddles or fans (the basis of this Invention) sucking or drawing in air by the
eye or opening of the casing and refrigerating it around the stone in such
quantity as may be desirable for completely cooling the working stones as
well as the grist; the flour consequently issues cold, and therefore in its
conversion into bread yields considerably more than ordinary flour; there is
also much less evaporation in the grinding. A', fixed stone; B, box let into
the stone A¹; C, wooden drum or casing enclosing the stones and the appa-
ratus; E, helicoidal paddles or fans in wood and iron, removeable at pleasure ;
H, introduction of air by the eye of the casing; L, metal crown fixed on the
eye of the casing, and permitting the entrance of air by means of a register
with two horizontal slides; M, exhaust conduit through which air is
continuously drawn from the casing; N, vase receiving the continuous
draught of air and the evaporation from the stone, and directing them into
the casing.
The principal object of this Invention is to permit the use of the millstone
itself without the aid of any other mechanical movement to obtain the
refrigeration of the air in passing between the two stones, thus reducing this
machine to the greatest simplicity.
Numerous experiments have proved to the Inventor that by the aid of the
running stone a regular current of air might be established around this stone
with paddles or fans, more or less numerous, of various shapes and dimensions,
and placed at various angles, and all such modifications and applications are
therefore reserved.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed 2
by the said William Edward Gedge in the Great Seal Patent Office on
the 20th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of the Firm of John Gedge and Son, of No. 11, Wellington
Street, Strand, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Gedge, Her special licence that I, the said s
William Edward Gedge, my executors, administrators, and assigns, or such

page_text: others as I, the said William Edward Gedge, my 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 "IMPROVED APPARATUS APPLIED TO MILLSTONES FOR GRINDING WHEAT AND
OTHER GRAIN," a communication to me from abroad by Pierre Baillargeon, of
39, Faubourg St. Martin, Paris, France, upon the condition (amongst others)
that I, the said William Edward Gedge, 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 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 William Edward Gedge, 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 :-
The apparatus, the subject of this Invention, will be best understood by
reference to the annexed Sheet of Drawing forming part of this Specification,
Figure 1 being a sectional elevation of a pair of millstones with this
improved apparatus applied thereto, and Figure 2 a plan view of same.
a, pendant isolator; A, running stone on which are fixed the helicoidal
paddles or fans, the basis of this Invention, sucking or drawing in air by the
eye opening of the casing, and refrigerating or cooling it around the stone in such
quantity as may be desirable for completely cooling the working stones as well
as the grist, the flour therefore issues cold, which gives to its panification a
yield very considerably greater than that of ordinary flour, and much less
evaporation in the working of the stone. A¹, fixed stone; B, box let into the
stone A¹; C, wooden drum or casing enclosing the stones and the apparatus;
E, helicoidal paddles or fans in wood and iron, removeable at pleasure;
H, introduction of air by the eye opening of the casing; L, metal crown fixed
on the eye opening of the casing, and permitting the entrance of air by means
of a register with horizontal slides; M, exhaust conduit with continuous
draught of air; N, vase receiving the continuous draught of air and the
evaporation from the stone, and directing them into the casing..
-
To sum up. The principal object of this Invention is to permit the use of
the millstone itself without having recourse to any mechanical movement to

page_text: obtain the refrigeration or cooling of the air in passing between the two stones
which reduces this machine to its greatest simplicity.
Numerous trials have proved that by the aid of the running stone a regular
current of air may be established around this stone with paddles or fans, more
or less numerous, of various shapes and dimensions, and placed at various
angles, and claim is therefore made to all these various alterations and
applications.
In witness whereof, I, the said William Edward Gedge, have hereunto
set my hand and seal, this Twentieth day of June, in the year of our
Lord One thousand eight hundred and sixty-seven.
W. E. GEDGE. (...)
