page_text: This Print is in accordance with the Original Specification as it stands after
Amendment (under Section 11 of the Patents, &c. Act, 1883) as required by the
decision of the Comptroller General of the 26th day of July 1897.

Improvements in Apparatus or Machinery for Extracting Dust and
the like from Oats, Grain, Cut Chaff, and the like Materials.
I SEPTIMUS COWL, of 10, Fieldhead Terrace, Samuel Street, Leeds, Cabinet Maker,
do hereby declare the nature of this invention to be as follows:-
According to my invention the hopper is or may be arranged with a worm or spiral
for feeding the material to the first compartment of the cleaning cylinder. Also an
eccentric is keyed on to the end of the cylinder shaft and connected by rod or lever
to a shaft having brushes arranged thereon, by this means a rocking motion is
imparted to the brushes for cleaning the perforated wire or screen on the fan.
Instead of this eccentric arrangement, pulleys and belts may connect the said shafts
and by this means a revolving motion can be imparted to the said brushes if preferred.
Also a series of spiral blades are fixed on the first dressing compartment of the
cylinder shaft by tabs or the like means. The said blades are arranged to leave
spaces between them and the said shaft.
Arranged at the bottom of the machine is a fan which withdraws or extracts by
suction the dust or the like from the material and passes it through trunk pipes into
dust chambers.

Improvements in Apparatus or Machinery for Extracting Dust and
the like from Oats, Grain, Cut Chaff, and the like Materials.
I, SEPTIMUS COWL, of 10 Fieldhead Terrace, Samuel Street, Leeds, Cabinet
Maker, 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:-
This invention has for its object to provide simple and efficient apparatus or
machinery for extracting dust and the like from oats, grain, cut chaff, and the like
materials.

Fig. 3 is a plan.
Fig. 4 is a sectional elevation of modification of my invention as applied for
treating oats.
Fig. 5 is an end elevation of same.
According to my invention the hopper A is or may be arranged with a worm or
spirat for feeding the material to the first compartment B of a cleaning cylinder C,
the surface of which first compartment is formed with a suitable mesh perforation or
apertures, so that heavy dust can pass through into a chamber D without the
material, which by the action of the cylinder is carried forward into the second
compartment E, having an outer surface formed also with a mesh perforation
or apertures. The chop or other material falls from the said cylinder into a
chamber F.
Arranged at the bottom of the machine is a fan G, which withdraws or extracts
by suction through the screen H the dust or the like from the material and passes it
through a trunk pipe J into dust chainbera which may be situated at any required
position. An eccentric may be keyed or otherwise on the cylinder shaft K, and
connected by rod or lever to a shaft L having a brush M thereon, by this means a
rocking motion is imparted to the said brush for cleaning the screen H in connection
with the fan G.
Instead of the eccentric arrangement pulleys N and belt O may connect the
said shafts and by this means a revolving motion can be imparted to the said brush if
preferred. The opposite ends of the said shafts being connected by belt P and pulleys P
and P2. The fan G by means of the arrangement aforesaid receives a reverse or
opposite motion to the cylinder. The hopper A has arranged in connection with it a
magnet R, by which nails and other metallic substances can be arrested before they
reach the first compartment B of the cylinder C, these can be cleaned out through
door S forming part of the hopper A. Arranged upon the shaft L are scrapers T
which revolve with the same and are for cleaning or forcing out chop or dressed
material through the spout U. The long straws can be taken out through spouts V
arranged at the sides or through the end of the machine, Brushes W may be
arranged in the second compartiment and spiral blades forming beaters X. in the
first compartment, or beaters X may be arranged throughout the whole of the
cylinder C.
My invention may be used in connection with a chop cutting machine or
independently as required.
In Figs. 4 and 5 is shown an arrangement or modification of my invention suitable
for treating or dressing onts or grain. According to this arrangement the barrel
or cleaning cylinder C is preferably conical, and the fan G is arranged opposite
thereto, by this means the dust is drawn upwards, and the material falls down the
spout, which is fitted with boards or louvres Z so as to retard the same.
In some cases the fan G instead of being carried on the shaft L may be fixed on the
cylinder shaft K.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a machine for the purposes aforesaid, the combination of a fan working so
as to withdraw or extract the dust from the material, substantially as shown and
described.
2. In a machine of the kind referred to, the combination of the fan G, working in
connection with a cylinder C, constructed and operating, substantially as and for the
purposes set forth.
3. In a machine of the kind referred to, the employment of scrapers T for removing
the material dressed, substantially as set forth.
4. In a machine of the kind referred to the employment of a magnet R by which

page_text: nails or other metallic substances can be arrested and withdrawn, substantially as set
forth.
5. The combination with a chop cutting machine of a dresser or machine
constructed and operating, substantially as and for the purposes set forth.
