Year: 1874

page_text: LETTERS PATENT to Richard Chambers, of Bow, in the County of
Middlesex, for the Invention of "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR CLEANING WHEAT AND OTHER GRAIN."
Sealed the 16th March 1875, and dated the 12th December 1874.

PROVISIONAL SPECIFICATION left by the said Richard Chambers at
the Office of the Commissioners of Patents, with his Petition, on
the 12th December 1874.
I, RICHARD CHAMBERS, of Bow, in the County of Middlesex, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR CLEANING WHEAT AND OTHER GRAIN," to be as
follows:-
This Invention has for its object the cleaning or scouring of wheat
and other grain, and consists of an improved arrangement of machinery
or apparatus by means of which the surface between which the wheat
or other grain is caused to pass is greatly increased within a small
compass.

page_text: I employ a cylinder or vessel, which is supported in suitable manner
in a horizontal position, and centrally therein is a shaft mounted in foot-
steps or bearings, and capable of revolving. Upon the bottom of the
vessel and within it are concentric divisions or internal cylinders of steel,
wire, or other substance with outlets or spaces therein, and keyed to the
shaft is a horizontal disc or radial arm with blades or beaters on the
under side thereof. This disc or the radial arms rotates within the vessel,
and the blades or beaters extend within the concentric divisions or
internal cylinders, or this arrangement may be inverted. The sides of
said concentric divisions with the blades, which may be so placed as
to form a wedge, form the rubbing or scouring surfaces for the wheat.
The blades or beaters may be of metal, or wood encased in metal, or
bo brushes of steel, wire, whalebone, or cane, or may be of glass.
The wheat is fed through an opening or hopper in the cap or cover
and revolving disc close to the shaft, and by the action of the beaters is
caused to circulate or pass through the outlets or spaces in the con-
centric divisions to the outer cylinder or space, whence it is carried by a
shoot to be further treated, as may be desired. Two or more of these
cylinders and discs may have the same shaft running through them,
and the wheat as it leaves the first or upper one might be conducted to
the next lower one.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Richard Chambers in the Great Seal Patent Office 2
on the 11th June 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
CHAMBERS, of Bow, in the County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twelfth day of December, in the year 3(
of our Lord One thousand eight hundred and seventy-four, in the

page_text: said concentric divisions with the blades, which may be so placed as
to form a wedge, form the rubbing or scouring surfaces for the wheat.
The blades or beaters may be of metal, or wood encased in metal, or
be brushes of steel, wire, whalebone, or cane, or may be of glass.
The wheat is fed through an opening or hopper in the cap or cover
and revolving disc close to the shaft, and by the action of the beaters is
caused to circulate or pass through the outlets or spaces in the con-
centric divisions to the outer cylinder or space, whence it is carried by a
shoot to be further treated, as may be desired. Two or more of these
cylinders and dises may have the same shaft running through them,
and the wheat as it leaves the first or upper one may be conducted to
the next lower one.
In the accompanying Drawings Fig. 1 is a sectional elevation of an
apparatus constructed according to my Invention, consisting of three
cylinders and central shaft; and Fig. 2 a plan of one of the cylinders.
A, A¹, A², are horizontal cylinders; B, central shaft with horizontal
discs C keyed thereon, and D are blades or beaters on said discs C;
E are concentric cylinders of steel, wire, or other substance with outlets
or spaces E¹, see Fig. 2, to allow the wheat or grain under treatment to
circulate in the direction of the arrows to the outlet or shoots F.
The discs C or the radial arms rotate within the vessels A, A³, A³, and
the blades or beaters D extend within the concentric divisions or internal
cylinders E and constitute the rubbing or scouring surfaces. On the
dise C are shoulders or rims G, which prevent the grain from passing
over the concentric cylinders E between them and the said disc O, thus
ensuring that the grain is subjected to the full effect of the scouring.
The wheat is fed through an opening H or hopper in the cap or
cover I and revolving disc C, and by the action of the beaters D and
stop D¹ is caused to circulate or pass through the outlets E¹ in the
cylinders E to the outlet F to be further treated, as may be desired.
An exhaust fan is employed to remove dust and any light matter
produced by the operation of cleaning; and the shaft is driven by band
and pulley K, or in other desirable manner.
Having thus described the nature and particulars of my said Inven-
tion, I claim, the improvements in machinery or apparatus for cleaning

In witness whereof, I, the said Richard Chambers, have hereunto
set my hand and seal, this Eighth day of June, in the year of
our Lord One thousand eight hundred and seventy-five.
