Aberdeen, North Britain, Miller, Grain and Produce Merchant do hereby declare
the nature of the said invention for ▲ MACHINE FOR MANUFACTURING OATMEAL
AND OTHER MEALS OF SIMILAR COARSE NATURE to be as follows :-
This Invention, which relates to a machine for manufacturing Oatmeal and other
meals of similar coarse nature, has for its object to divide the "shelling" or grain
into two, three or more parts, and thereby avoid, to a great extent, the reduction
of the said "shelling" or grain, or part of it to a flour or to a more finely divided
condition than is required.
In carrying out this Invention, a roller is arranged to rotate upon a horizontal
axle. This roller is provided with longitudinal grooves of such dimensions as will
admit of one "shelling" or grain when in a correspondingly longitudinal position
being below the outer surface of the said roller. The roller which may be composed
of discs or rings of alternately larger and smaller diameters is provided with a series
of annular grooves of sufficient width to allow of the rolling therein of cutters
which are either carried upon an adjacent roller or held tangentially within the
grooves so formed. These two rollers are or may be geared together by means of
toothed wheels or their equivalent, and they may be driven at corresponding or
varying speeds. At the upper part of the herein first mentioned roller, a further
roller, preferably with a surface of India Rubber or equivalent elastic material and
driven by the friction between the surface of it and the fluted roller, is guided in
forked or equivalent bearings which admit of a vertical motion being imparted to
the said roller-To this roller an endwise reciprocating motion is imparted by
means of cams or their equivalents arranged at one or at both ends thereof.
Between the rubber or equivalently covered roller and the roller carrying the
cutters or the tangential cutters there is arranged a sheath or cover close upon the
surface of the fluted roller and at the lower part of this sheath or cover slits are
formed for admitting the cutters thereinto.-The upper part of this sheath or cover
is connected to the underside of the hopper by which the "shelling" or grain is
charged into the machine.-This hopper is formed with two branches one on either
side of the rubber-covered roller, so that the "shelling" or grain is charged

I, JAMES MILNE, of the firm of Milne Brothers, of the Oity and County of
Aberdeen, North Britain Miller, Grain and Produce Merchant do hereby declare the
nature of my said invention for A. MACHINE FOR MANUFACTURING OATMEAL AND
OTHER MEALS OF SIMILAR COARSE NATURE and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My Invention, which relates to a machine for manufacturing Oatmeal and other
meals of similar coarse nature, has for its object to divide the "shelling" or grain,
into two, three or more parts, and thereby avoid, to a great extent, the reduction of
the said "shelling" or grain, or part of it, to a flour or to a more finely divided
condition than is required.
In carrying out this Invention, a roller is arranged to rotate upon a horizontal
axle. This roller is provided with longitudinal grooves of such dimensions as will
admit of one "shelling" or grain when in a correspondingly longitudinal position,
being below the outer surface of the said roller The roller, which may be composed
of discs or rings of alternately larger and smaller diameters, is provided with a
series of annular grooves of sufficient width to allow of the rolling therein of cutters
which are either carried upon an adjacent roller or held tangentially within the
grooves so formed. These two rollers are or may bo geared together by means of
toothed wheels or their equivalent and they may be driven at corresponding or
varying speeds. At the upper part of the herein-first mentioned roller, a further
roller, preferably with a surface of India Rubber or equivalent elastic material and
driven by the friction between the surface of it and the fluted roller, is guided_in
forked or equivalent bearings which admit of a vertical motion being imparted to
the said roller. To this roller an endwise reciprocating motion is imparted by
means of cams or their equivalents arranged at one or at both ends thereof.
Between the rubber or equivalently covered roller and the roller carrying the
cutters, or the tangential cutters, there is arranged a sheath or cover close upon the
surface of the fluted roller and at the lower part of this shoath or cover slits are
formed for admitting the cutters thereinto. The upper part of this sheath or cover
is connected to the underside of the hopper by which the "shelling" or grain is
charged into the machine. This hopper is formed with two branches one on either
side of the rubber covered roller, so that the "shelling" or grain is charged down
direct upon the fluted roller at these two parts, the intervention of the roller
between, and by the reciprocating motion thereof, causing the "shelling" or grain
to rest in its required longitudinal position.
Wire brushes or their equivalents are arranged in close proximity to the fluted
roller and the roller carrying the cutters, so that any small particles of cut grain or
meal, adhering thereto, are removed when passing on to the said brushes.
The "shelling" or grain charged into the machine at the upper part is collected
and delivered by a hopper at the lower part, from which it may be taken to any
required receptacle.

page_text: In order that my said Invention may be properly understood and readily carried
into effect I will proceed to describe the Drawings hereunto annexed.
Figure 1 is an end elevation of a machine constructed according to and
constituting my present Invention.
Figure 2 is a front elevation of the same, a portion of the mechanism being
represented as broken away.
"
In carrying my present Invention into practice, I arrange the roller a, to rotate
upon the horizontal shaft b. This shaft b, is carried in the bearings c, formed in
the framing d, of the machine, and is actuated by a band from any adjacent shaft
or motor passing around the band pulley e, or the said shaft b, and its connections
may be operated by any other convenient means. Preferably upon the end of the
shaft b, opposite to that occupied by the band pulley e, is secured the toothed gear
wheelf, which actuates the cutter roller g, hereinafter described. The heroinfirst
mentioned roller a, is provided with the longitudinal grooves h, which are of such
depth as will admit of one "shelling or grain, when in a correspondingly
The
longitudinal position, being below the outer surface of the said roller u.
roller a, is further provided with the annular grooves i, which are of sufficient
J. These
width to allow of the rolling therein of the blades of the cutter roller
annular grooves i, may be turned out of a solid roller, or they may be constituted
by discs or rings of varying sizes arranged alternately along the length of the said
roller, under the latter form of construction the said discs are compressed
longitudinally by means of bolts and nuts or their equivalents. The blades or
cutters used in connection with my present Invention, may be of a straight form
or of a form approximating thereto, and may be secured with their cutting edges
tangentially within the grooves i, by means of studs and fly nuts or by their
equivalents, the form however, which I prefer to adopt is that shewn upon the
annexed drawings, the blades or cutters there represented being of an annular form
arranged upon a roller. This roller g, as herein before mentioned is rotated by the
toothed gear wheel f, which engages with the second toothed gear wheel j, which is
secured to the shaft k, upon which, the said roller g, is mounted, the shaft k, being
supported in bearings formed in the framing d. The two gear wheels f, and j, as
represented upon the annexed drawings are of such dimensions as will rotate tho
rollers a, and g, with an equal, or nearly equal, surface speed, but the dimensions
of those two wheels relatively with each other may be varied so as to rotate the
roller a, with a greater or lesser surface speed than the roller g. The two rollers a,
and y, in place of being geared together in the manner hereinlast described, may be
geared together by means of friction, or other equivalent gearing, and may, likewise
under such form, be operated at similar or dissimilar surface speeds.
At the upper part of the roller a, the roller l, preferably with a surface of India-
Rubber or equivalent frictional material, is guided in the bearings m, which admit
of the said roller l, receiving a vertical motion therein. The roller l, is rotated
by the friction of its surface with that of the roller a, and upon the shaft n, of the
said roller , any suitable arrangement of mechanism is provided for imparting to it
an endwise reciprocating motion. The inechanism represented upon the annexed
drawing for effecting this motion consists of the pin o, secured to any adjacent and
rigid part of the machine, engaging with the groove of the cam p, which is secured
upon, and rotates with, the shaft n.
or
Around, and close to the surface of the roller a, at that part situated between the
rollers g, and l, I arrange the sheath or cover q, the part of which adjacent to the
cutter roller g, is formed with slits for the passage therethrough of the blades or
cutters of such roller. The upper part. of this sheath or cover q, is connected to
the underside of, or to the branch 7, of the hopper 8, by which the "shelling
grain is charged into the machine. This hopper 8, is formed with two branches,
the branch 7, last referred to, which delivers the grain on to the roller a, at the
upper part of the sheath or cover q, and the branch t, which delivers the grain on
to the surface of the said roller a, at the part nearly approaching the roller 7, and
at the opposite side thereof.

page_text: The wire brushes u, or their equivalent employed in connection with my
Invention are secured beneath the framing d, in any convenient manner in such
positions that they shall remove any particles of cut grain or meal adhering to the
rollers a, and g. These particles so removed with the cut grain or meal otherwise
falling from the machine, are collected by the hopper v, and the shoot w, by which
they are delivered into bags, sacks or other receptacles.
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
A machine for manufacturing oatmeal and other meals of similar coarse nature
wherein are employed a roller a, having longitudinal grooves h, and annular
grooves i, a cutter roller g, and a longitudinally reciprocating rubber or equivalently-
covered roller, brushes u, and hoppers s, and v, and their attachments all operating
substantially as and for the purposes herein before set forth with reference to the
annexed drawings or the mechanical equivalents of all or any of the said parts,
