PROVISIONAL SPECIFICATION left by the said William Edward Gedge
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd September 1871.
I, WILLIAM EDWARD GEDGE, of No. 11, Wellington Street, Strand,
in the County of Middlesex, Patent Agent, do hereby declare the
nature of the said Invention for "AN IMPROVED MACHINE OR APPARAtus
FOR CLEANSING GRAIN," a communication to me from abroad by Charles
Vigreux, of 37, Boulevard Bonne Nouvelle, Paris, France, Miller, to
be as follows:-

page_text: hitherto used for cleaning grain by reason of their too powerful action
raise upon the corn pellicles of bran and reddish spots, which must be
subsequently removed. By this Invention the sheet-iron rasps are
replaced by a vertical wire brush turning in a sheet-iron jacket. The
corn passes between the jacket and the brush, is there submitted to the
action of the brush, and passes thence to a fan for the removal of the
remaining dust and particles of straw.

visional Specification, Fig. I. is a sectional elevation, and Fig. 2 a plan of
a machine constructed according to this Invention.
a, a, a, cross pieces of oak, or other suitable material, forming the
framing of the machine; b, cross piece with socket receiving the pivot
of the column c; c, conical wooden column furnished with cards. It is
upon this card that the apparatus is based, and its use constitutes the
principle of this Invention; d, d, d, combination of wooden rings or
hoops and perforated sheet iron surrounding the column and forming
the aforesaid jacket. It is in the space comprised between the column
and the jacket that the action of the cards upon the corn takes place;
e, entrance of the corn into the column of the machine; h, exit of the
corn from the column to enter into the conduit i, where it is submitted
to the action of the fan f; f, fan removing the particles of straw and the
dust which may remain mixed with the corn; i, exit of cleaned corn;
1, exit of bad grain; m, exit of particles of straw and dust; p, p, p,
pulleys and toothed gearing working the machine and the fan; q,
collector for preventing the grain piling in the machine; s, screw fitted
beneath the socket and serving to raise and lower the column, which,
being conical, approaches or recedes from the jacket at will according to
the work to be done.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Gedge in the Great Seal Patent 30
Office on the 21st March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD GEDGE, of No. 11, Wellington Street, Strand, in the County of
Middlesex, Patent Agent, send greeting.

"
Advantages of this Cleansing Brush or Brosseur-Nettoyeur.”—The
principal advantage of this machine or apparatus is to remove spots or
the effects of blight from corn almost without making any waste and
without the aid of any other apparatus. This machine will be of great
value to the miller, especially in years when the wheat pullulates.
It replaces, advantageously, cleansings by means of sheet-iron rasps,
which only imperfectly remove the impurities from corn and have the
further defects of attacking the husk of the corn by their too energetic
action, and of raising on its surface pellicles of bran and red spots, the
effect of which in the grinding is that the corn in passing beneath the.
millstone frees itself from these pellicles of bran by rolling on itself,
they then come beneath the stones and are reduced to flour, and thus
flour often assumes a dead yellow colour.
:
The apparatus the subiect of this Invention will remedy this defect

page_text: This Invention also offers great advantages to farmers, who often are
compelled to make heavy reductions in price because their corn is
spotted or coated with impurities.
In witness whereof, I, the said William Edward Gedge, have
hereunto set my hand and seal, this Twenty-first day of March,
in the year of our Lord One thousand eight hundred and
seventy-two.
