Improvements in Apparatus for Separating, Sorting, or Dressing
Flour or other Cereal Substances.
A communication from abroad by HENRY BAKER, Mill Proprietor, and RICHARD
KENNETH BAXTER, Head Miller, both of Constantinople.
I, FREDERICK WILLIAM BAKER, of 134 Fenchurch Street, in the City of
London, Solicitor, do hereby declare the nature of this invention to be as
follows:-
This invention relates to apparatus for the separating, sorting, or dressing of
flour or other cereal substances, and has for its object the saving of wear upon the
silk used as a screen or sieve, to graduate the material so as to give an even
dressing, and to prevent, by the gentle action of the apparatus, the pulverizing of
the material required to be dressed.
The apparatus consists of a reel, externally covered with screening silk or cloth,
and provided internally with a cylinder, preferably of zinc, lying within a short
distance of the external cylinder of silk or cloth and carrying the supports for the
said silk or cloth.
The internal cylinder is slightly conical in shape, and of a suitable dimension.
It is mounted upon a spindle on which the reel revolves, and is bolted at suitable
distances to discs, preferably of iron, forming the head and tail plates of the
external cylinder of silk or cloth.
The conical interual cylinder has a spiral conveyor about its periphery, formed
of a rod mounted on the inner cylinder by suitable brackets or supports.
This forms a gentle conveyor or lifter and elevator of the material to be dressed
which lies between the inner and outer cylinders.
The outer cylinder is formed of silk or cloth stretched on the two head and tail
discs before mentioned, and upon supporting rings, set at suitable intervals upon
the inner cylinder. This silk or cloth screen forms the dresser.
The inner conical cylinder and its spiral conveyor or elevator causes a gentle
action of the material upon the silk covering, and the spiral conveyor also causes
the material to graduate to the tail of the machine, giving an exceptionally even
dressing without pulverisation or injury to the material to be dressed."

page_text: Improvements in Apparatus for Separating, Sorting, or Dressing
Flour or other Cereal Substances.
A communication from abroad by HENRY BAKER, Mill Proprietor, and RICHARD
KENNETH BAXTER, Head Miller, both of Constantinople.
I, FREDERICK WILLIAM BAKER, of 134 Fenchurch Street, in the City of
London, Solicitor, 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 relates to apparatus for the separating, sorting, or dressing of
flour or other cereal substances, and has for its object the saving of wear upon the
silk used as a screen or sieve, the graduation of the material so as to give an even
dressing, and the prevention by the gentle action of the apparatus, of the
pulverisation of the material to be dressed.
The improvement consists in the mode of connection between the internal and
external cylinders, whereby the cereal to be dressed has free access into the outer
cylinder, and to almost the full surface of the silk or covering, with uninterrupted.
travel from head to tail of the machine; and further in the construction of a spiral
conveyor between the internal and external cylinders, acting both as a support and
elevator or conveyor to the cereal material.
And in order that this invention may be the better understood, I will now proceed
to describe the same in relation to the drawings hereunto annexed, reference being
bad to the letters and figures marked thereon. Like letters refer to like parts in
the various figures.
Figure 1 is a longitudinal section of the improved reel.
Figure 2 is a perspective view of the reel with the outer covering of silk
.removed.
Figure 3 is a detail of the silk supporting band and bracket.
Figure 4 is a detail of the conveyor rod and bracket.
This apparatus consists of an internal cylinder A, preferably of zinc, mounted
upon a central shaft by which the reel is rotated on suitable bearings.
This zinc cylinder A is slightly conical in form, and supports a series of circular
bands C by means of brackets K, about its periphery, to which is attached an outer
covering of silk or cloth D, forming an external parallel cylinder, outside, but close
to the internal conical zinc cylinder.
The said external cloth or silk cylinder D, is also stretched on two end plates E,
preferably of iron, which are also mounted on the central shaft B, with a central
annular opening F, and the said discs or end plates E are also attached to the ends
of the zinc cylinder A by bolts G.
The cereal to be dressed is fed through the central aperture F, and thus passes
centrifugally at once to the space between the internal and external cylinders, and
owing to the manner in which the silk cylinder is supported, the cereal passes
without obstruction to the discharge buckets L at the tail of the cylinders, travelling
the full area of the silk or cloth.
Upon the periphery of the zinc cylinder A, is fitted a spiral conveyor H, formed
by a continuous spiral rod mounted upon standards M, and projecting to a suitable
distance, so as to lie between the two cylinders A and D, and thus forms a gentle
conveyor and lifter, or elevator, of the cereal substances, between the internal and
external cylinders, which it is required to dress.
The inner conical cylinder A, and its spiral conveyor H, causes a gentle action
of the cereal substance or flour upon the silk covering, and causes the material to

page_text: graduate to the tail of the machine, giving an exceptionally even dressing, without
pulverisation of, or injury to, the material to be dressed.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1st. In an apparatus for separating, or dressing flour or other cereal substances,
an external cylinder of silk or cloth; circumferential bands C; brackets K,
supporting same, and fixed to internal conical zinc cylinder; end plates or discs E,
mounted on a rotating shaft, and spaced from ends of internal cylinder; central
orifices therein; and bolts attaching and spacing said discs to ends of zinc cylinder,
substantially as described.
2nd. In an apparatus for separating or dressing flour or other cereal substances,
a spiral rod conveyor H, and brackets M, supporting same on internal plate
cylinder, and lying mid-way between internal plate and external silk cylinders, for
elevating and conveying the cereals, substantially as described.
