Improvements in Machinery for Separating or Dressing Flour,
Middlings, Semolina, Grain, Seeds, or other Dry Granular or
Pulverulent Substances.
I ROBERT CREASER of Maryborough in the Colony of Queensland, Australia,
Flour Miller, 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 consists in an improved apparatus for dressing flour, grain,
middlings, semolina, seeds or other dry granular or pulverulent substances and is
explained as follows together with the accompanying drawings-
The letters of reference apply to corresponding parts in all figures.
Fig. 1 is a sectional elevation and Fig. 2 a ground plan.
A is a spindle about 1½ diameter running through the centre of the machine.
A driving pulley keyed to spindle.
B brass-bushed collar bolted or otherwise secured to framework.
B¹ footstep bolted or otherwise secured to framework in which the spindle A
revolves.
C framework mortised or bolted together made out of about 3″ × 3″ wood or
iron of suitable section and strength.
D and D' discs of wood or metal (of which there may be any number) keyed on
to the spindle as shewn or secured thereto by any other suitable means, to which
are fixed at an oblique angle to the spindle, paddles a and a¹ preferably of sheet or
plate iron about 24 long by 2" wide, the ends being turned over at right angles,
for bolting or otherwise fastening the same to the underside of the discs D and D¹.
E and E¹ series of discs (of which there may be one or more series) of metal or
wood held together and connected to the discs D and D' by bolts and nuts F
and F1 running through same from the upper side of the top disc to the underside
of the bottom disc, four bolts in each series of discs being necessary to ensure
rigidity, the heads of the bolts are countersunk flush in the top disc.
The discs in E and E¹ series are kept at equal distances apart by ferrules as
shewn in detail Fig. 3. In both series of discs the space between each may be
regulated to suit the kind of substance to be treated by employing ferrules of
different lengths and any number of discs may also be used.
There are holes in the centre of each disc (excepting in the bottom or base disc)
of necessary diameter gradually decreasing in size in each successive disc from the
top to the lower one, the edge of these holes in the E series may be slightly turned
up as shewn at D', or may be flat and vertical one to the other same as E' series,
with this exception both series of discs are similar.
H is a receiving table of wood or metal with bevelled wood or angle iron at
outside edge for fixing screen P and securing table to framework by bolts S as
shewn in Fig. 1. In the centre of this table is a hole large enough for the insertion

page_text: of the spindle A and the passage of the material after manipulation to the serie
of discs E' immediately below, the hole in the centre of the table is bushed o
collared so as to form a short tube.
I is a receiving table secured by bolts S to framework.C.in a similar manner to
table H with hole in centre only sufficiently large to take the spindle A around
which it fits closely, four or more bolts are necessary to firmly secure the tables H
and I.
Goutlet or opening in receiving table H to series of discs E.
means
L are arms secured to the spindle A. with set screws or by other suitable
and K wooden or metal paddles screwed or otherwise fastened to the arms L.
P screen of silk, woven wire, perforated zinc or any other suitable covering
according to the material operated upon and fixed at any suitable distance from the
periphery of the discs.
1
R outside case, close fitting, of wood iron or any other suitable material to
prevent the escape of dust,and fixed at any desired distance from screen P.
O and O' top and bottom casing of machine, the top casing being supported, by
brackets-X secured to the framing and casing as shewn in Fig. 1.
T lugs or brackets secured to casing and framework for maintaining machine in
position.
U'shoot or spout for feeding machine.
V hopper.
M shews opening in receiving table I through which the material'operated upon
is discharged falling into the shoot M¹ fixed on one side of the spindle A
N shews opening in the bottom casing O' through which the material collected
by the paddles K is discharged, falling into the shoot N'..
I wish it to be understood that I do not confine myself to any, particular size nor
to any particular kind of material for construction.
I now describe the process of working:
The flour, grain, or other material is fed on to series of discs. E and..disc D
through the hopper V by means of shoot U.
The holes in the centre of discs E. being largest in the top disc and gradually
decreasing in size to the lower one provides for an equal distribution of material
to the surface of each disc, each layer of material getting thinner as it reaches
the periphery of each disc, the centrifugal action of the discs when run at a
peripheral speed of from 1000 to 1500 feet per minute impels the material in a
direct line or at right angles against the cover or screen P thereby.separating or
dressing the same.
Where more than one series of discs is used the partly finished material falls
down on to the table H and is propelled by the paddles a to the opening G where
it falls through and is distributed upon the next series of discs E' which again,
impels it against the screen P in the same manner as above described in first series
the material falling on outer edge of table I propelled by the paddles A¹ to
the opening M and is discharged from the machine by shoot M..
The material forced through the screen P which surscribes the discs- falls upon
outer edge of table O' and is propelled by the paddles K to the opening: N. and:
discharged from the machine by shoot N'.
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 a machine for separating, or dressing flour, grain &c., and other pulverulent 6
and granular substances a series or arrangement of discs fixed to a vertical spindle-
or shaft whereby, the material manipulated is impelled in a direct line towards.the.
screen or cover P as hereinbefore substantially described. and as shewn, in accom÷-
panying drawings as and for the purpose set forth.
2. In a machine for separating or dressing flour, grain, &c. and other pulverulent. 5
and granular substances the arrangement and series of discs fixed one above another.

page_text: and revolving horizontally substantially as hereinbefore described and as shewn in
accompanying drawings as and for the purposes set forth.
3. The particular pattern and arrangement of details of construction and the
device generally substantially as hereinbefore described as and for the purposes set
forth.
