Improvements in Apparatus or Machinery for Extracting Dust and
the like from Cut-chaff, Grain, and the like Materials.
1, GEORGE PORTEUS, of Hunslet New Road, in the City of Leeds, Engineer
and Millwright, do hereby declare the nature of this invention to be as
follows;
My invention has reference to certain improvements in apparatus or machinery
for extracting dust and the like from cut-chatt, grain, and like materials.
According to my invention I mount (in a suitable frame) a cylinder having a
rough or medium-sized perforation or mesh. This cyhnder is made of one or
more sized perforations or mesh throughout, Carried on the cylinder shalt and
working inside the said cylinder are wipers for feeding or distributing the
material through the said cylinder, the material being red from a hopper on
the top of the machine, or other convenient position, or the material may be
fed by means of a worm in the said hopper.
For extracting the dust and the like I employ fans acting on the suction
principle, and not like an ordinary blower, these tans I arrange on shafts which
are driven from the cylinder shart by pulleys and belts or other such means.
Opposite or in connection with the fans I arrange screens with brushes for work-
ing on each side, so as to clean the screens, and prevent the formation of any
deposit on the mesh, and so keep it from being permanently closed.
In connection with the fans are trunk pipes into which the dust is passed,
and taken from the machine, these pipes may be arranged to pass the dust out
in a vertical, horizontal or other direction.

Improvements in Apparatus or Machinery for Extracting Dust and
the like from Cut-chaff, Grain, and the like Materials.
I, GEORGE PORTEUS, of Hunslet, New Road, in the City of Leeds, Engineer
and, Millwright, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
My invention has reference to certain improvements in apparatus or machinery
for extracting dust and the like from cut-chaff, grain, and like materials.

page_text: My said improvements are applicable in this class of machinery for use in
connection with cylinders, barrels, shakers, sieves, riddles, or their equivalents,
either on the double or single action principle; and further, my said improve-
ments may be used, without being in connection with cylinders, barrels, shakers,
or the like, and on the double or single action principle.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a sectional elevation of cylinder machine according to my improve-
ments.
Fig. 2, is an end elevation.
Fig. 3, is a sectional elevation showing the cylinder dispensed with, and a
sieve, riddle, or shaker used in lieu thereof.
Fig. 4, is an end elevation of Fig. 3.
Fig. 5, is a sectional elevation, showing machine constructed without cylin-
der, shaker, or equivalent device, the sifting or dressing being performed, by
the action of the fans and screens only, the construction being on the double
action principle.
Fig. 6, is a modification of Fig. 5, showing single action arrangement only.
Fig. 7, is a further modification, showing fans arranged away from the
screens, and at a higher elevation, 'and either with or without a cylinder, or
barrel, or their equivalents.
According to this invention, (see Fig. 1,) I. mount, in a suitable frame A, a
cylinder B having a rough or medium sized perforation or mesh. This
cylinder B is made of one or more sized perforations or mesh throughout.
Carried on a shaft C and working inside the said cylinder B are wipers D for
feeding or distributing the material through the said cylinder, the material
being fed from a hopper or opening E on the top of the machine, or other con-
venient position, or the material may be fed by means of a worm in the said
hopper.
For extracting the dust and the like I employ fans F acting or the suction
principle, and not like an ordinary blower, these fans I arrange on shafts G
carried by bearings H, and are driven from the shaft C by pulleys J and
belts K, or other such means, such as chains and chain wheels. Opposite or in
connection with the fans F I arrange screens L, and brushes M carried by a
shaft N, mounted in bearings 0, and driven by a pulley P and belt, or other
such means, so that a revolving motion is given or imparted to the said brushes,
whereby they are caused to clean the screens, and prevent the formation of any
deposit on the mesch, and so keep such from being permanently closed. In
connection with the fans F are trunk pipes into which the dust is passed and
taken from the machine, these pipes may be arranged to pass the dust away in
a vertical horizontal, or other direction. The screens L may be arranged at
some or any required distance from the fans F, and connected to the fan casing
by trunk pipes or other suitable means.
The machine is driven from any convenient source of power, and as the
wipers D carry the material through the cylinder or barrel B the cut-chaff or
the like and dust or other impurities fall below the cylinder or barrel B, the
inclined or taper plane R, dividing such and passing it to the action of the
fans F, and screens L at each side of the machine, by this means the dust or
the like is extracted, and the cut-chaff or other material passes out of the
machine at the place S. The long straws or "cavings" pass out, from the cylin-
der or barrel B, at the end of the machine.
In Figs. 3 and 4, are shown the combination of my improvements with a
shaker, sieve, or riddle T arrangement. In this case a reciprocating motion is
imparted to the device T by the connecting rod U, this motion causes the long
straws or "cavings to pass out at V, while the chop or like material passes
or falls below, and is acted on by the fans F and screens L as before explained.
"

page_text: The machine is driven, so as to impart motion to the fan and brush shafts,
by means of countershaft and other parts, arranged in any convenient position.
In Fig. 5, is shown a double action machine, arranged without cylinder, or
the like, the material passing direct to the machine from the chopper.
Figs. 6 and 7 will be readily understood from the description previously given
respecting them.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is;-
-
1. In machinery or apparatus of the nature specified, the combination of fans
acting on the suction principle and screens (with brushes) arranged oppositely
to or in connection with the said fans, substantially as and for the purposes
such as set forth.
i
2. The combination of parts forming the improved machinery or apparatus
substantially as and for the purposes such as set forth.
