"IMPROVEMENTS IN
JOSEPH ELLISON, of Leeds, in the County of York.
MACHINERY OR APPARATUS FOR DRESSING FLOUR, SUCH IMPROVEMENTS BEING
ALSO APPLICABLE FOR SCREENING GRAIN."
I construct the framework of the machine of metal instead of wood, by which
means I obtain much greater firmness or rigidity, which is very desirable in machines
running at such high speeds.
The cylinder or reel on which the silk is laid and fixed is carried on a shaft in
suitable adjustable bearings on the frame ends.
"
I employ spur gearing instead of friction for imparting a rotary motion to the
on both end plates or
cylinder or reel, and for this purpose I provide or "cast
covers of the cylinder or reel a spur wheel, through which motion is imparted by
the assistance of other spur gearing from driving shaft. By gearing both ends
of the cylinder or reel I prevent any twisting during the rotary motion, and am
enabled to use lighter cylinders or reels than when driven from one end only, at
the same time having all the strength for its work.
I employ iron bars of a V shape to form the body or skeleton of the cylinder or
reel to support the silk; these are connected or coupled to the cylinder or reel end
plates or covers, and by their V form may be of extreme lightness, at the same time
as strong as necessary.
Through the centre of the cylinder or reel is passed the main driving shaft, which
carries the beater for throwing the meal against the silk; this shaft is mounted on
adjustable pedestals. The beater is composed of a number of blades fixed to lugs
or projections on rims of suitable wheels mounted and fixed on the driving shaft,
and in an angular direction to cause the bran to travel to the outlet end of the
machine.

page_text: At the end of the machine to which the supply pipe is fixed I extend the blades
of the beater forward, which ends I serrate. Within the flange, which is cast on
the end plate or cover, I provide any required number of pins; those, in combina-
tion with the serrated projecting blades, and being caused to rotate at different
speeds, detach or separate the material to be operated upon.
In order that the rolled or crushed meal (which is supplied to the machine) may
pass through this detaching or separating process I fit a wrought iron plate on the
end rimmed wheel, leaving an opening all round; this has the effect of compelling
all the material operated upon to come in contact with the serrated blades and pins
before entering the silk cylinder or reel. The silk cylinder or reel is fitted so as to
revolve upon bosses attached to the frame ends.
I further provide a circular brush, either of spiral or other form, to which a
rotary motion is imparted simultaneously with that of the cylinder for the purpose
of keeping open the meshes of the silk; this silk is mounted in adjustable
bearings.
Other parts of the machine not named are of ordinary construction.

the said Joseph Ellison in the Great Seal Patent Office on the 28th November

JOSEPH ELLISON, of Leeds, in the County of York. "IMPROVEMENTS
MACHINERY OR APPARATUS FOR DRESSING FLOUR, SUCH IMPROVEMENTS BEING
ALSO APPLICABLE FOR SCREENING GRAIN."
I construct the framework of the machine of metal instead of wood (the ordinary
mode) by which means I obtain much greater firmness or rigidity, which is very
desirable in machines running at such high speeds.
The cylinder or reel on which the silk is laid and fixed is carried on a shaft in
suitable adjustable bearings on the frame ends.
I employ spur gearing instead of friction for imparting a rotary motion to the
cylinder or reel, and for this purpose I provide or "cast" on both end plates or
covers of the cylinder or reel a spur wheel, through which motion is imparted by
the assistance of other spur gearing from driving shaft. By gearing both ends
of the cylinder or reel I prevent any twisting during the rotary motion, and am
enabled to use lighter cylinders or reels than when driven from one end only, at
the same time having all the strength for its work.
I employ iron bars of a V shape to form the body or skeleton of the cylinder or
reel to support the silk; these are connected or coupled to the cylinder or reel end
plates or covers, and by their V form may be of extreme lightness, at the same time
as strong as necessary.
Through the centre of the cylinder or reel is passed the main driving shaft which
carries the beater for throwing the meal against the silk; this shaft is mounted on
adjustable pedestals. The beater is composed of a number of blades fixed to lugs

page_text: or projections on rims of suitable wheels mounted and fixed on the driving shaft,
and in an angular or spiral direction to cause the bran to travel to the outlet end
of the machine.
"
At the end of the machine to which the supply pipe is fixed I extend the blades of
the beater forward, which ends I serrate. Within the flange, which is "cast on
the end plate or cover, I provide any required number of pins; these, in combina-
tion with the serrated projecting blades, and being caused to rotate at different
speeds, detach or separate the material to be operated upon.
In order that the rolled or crushed meal (which is supplied to the machine) may
pass through this detaching or separating process I fix a wrought iron plate on the
end rimmed wheel, leaving an opening all round; this has the effect of compelling
all the material operated upon to come in contact with the serrated blades and
pins before entering the silk cylinder or reel. The silk cylinder or reel is fitted so
as to revolve upon bosses attached to the frame onds.
I further provide a circular brush, either spiral or other form, to which a rotary
motion is imparted simultaneously with that of the cylinder, for the purpose
of keeping open the meshes of the silk; this brush is mounted in adjustable
bearings.
Other parts not named are of ordinary construction.
And in order that my Invention may be more completely understood reference
Fig. 1 is an end elevation; Fig. 2, a cross section; Fig. 3, a part longitudinal
section and clevation; Fig. 4, a part sectional plan.
a is the framework of the machine, which is constructed entirely of metal, for the
purpose of giving firmness and rigidity to the machine. b is the cylinder or reel,
on which the silk is laid; this is carried on a shaft c, mounted in adjustable
bearings & on the framework; e, f, g, and g¹ are the spur gearing which are
employed at both ends of the cylinder on reel b, e being fixed on the worm shaft h,
fon the plain shaft i, both of which are mounted respectively in the bearings j and k.
g is a spur wheel at one end of the cylinder, and g¹ is a spur wheel at the other
end; these are by preference "cast on the cylinder or reel end plates or covers
and ; m is the driving pulley, to which rotary motion is imparted to the silk
cylinder or reel, being transmitted thereto through the shaft c, pulleys n and o to
gearing e and f, thence to spur wheels g and g¹ on silk cylinder or reel end plates
or covers and l. By this arrangement of driving from both ends of the cylinder or
reel I prevent any twisting during the rotary motion thereof, and am enabled to use
lighter cylinders or reels than when driven from one end only.
»
In the formation of the body or skeleton of the cylinder or reel I employ metal
bars P, these being of a V shape, as shewn, and are coupled or connected to the
cylinder or reel plates or covers by any convenient known means, and by their
V form extreme lightness and strength are obtained.
On the shaft c is mounted and keyed a beater q, which is employed for throwing
the meal against the silk. The beater 7 is composed of a number of blades r fixed
to lugs or projections 8 on the rims of wheels t, which are mounted and fixed on the
shaft c.
The blades rare fixed in a spiral or angular direction in their length to
cause the bran to travel to the outlet of the machine after being freed from flour.
At the end u of the machine, to which the supply pipe v is attached, I extend the
blades forward, and serrate them, as shewn in Drawings, and within the flange w,
which is "cast on the end plate or cover l, I provide any required number of
pins or teeth ; these, in combination with the serrated projecting blades, and
being caused to rotate at different speeds, detach or separate the material operated
upon.
"

page_text: In order that the rolled or crushed meal may pass through the detaching or
separating process I fix a plate y at z on the wheel t, leaving an opening all round
at 1; this has the effect of compelling all the material operated upon to come in
contact with the serrated blades r and pins or teeth x before entering the silk
cylinder or reel.
The end plates or covers and l¹ revolve upon bosses 2 and 2¹ attached to the
frame ends, their rotation being separate and distinct from that of the shaft c and
the detachers. I further provide a circular brush 3 in adjustable bearings, and
impart a rotary motion thereto simultaneously with that of the cylinder 6 for the
purpose of keeping open the meshes of the silk.
Other parts of the machine may be of ordinary construction.
Having now described the nature of my said Invention, and described with the
aid of Drawings how the same may be carried into practice, I would have it under-
stood that I do not limit myself to the exact details or configuration of the parts I
have expressed and illustrated on the accompanying Drawings, as the same may be
varied or modified without departing from the nature of my Invention, but what I
do claim and desire to be secured to me by Letters Patent is,―
First. The arrangement and application of blades projecting and serrated at
end u of the machine, in combination with the pins or teeth x within the flange w,
substantially as and for purposes herein set forth.
Second. The arrangement and application of means employed for driving the
cylinder or reel b with gearing at both ends, substantially as and for purposes
herein set forth.
Third. The arrangement and combination of the various parts forming the machine,
substantially as and for purposes herein set forth.
In witness whereof, I, the said Joseph Ellison, have hereunto set my hand
and seal, this Twenty seventh day of November, in the year of our Lord
One thousand eight hundred and seventynine.
