-An Improved Mixing Machine.
I, JAMES BIBBY, of Bixteth Street, Liverpool, in the County of Lancaster,
Seed Crusher, do hereby declare the nature of this invention to be as follows:-
My invention has for its object to provide improved machinery for mixing
pulverulent and granular material with the object chiefly of causing two or more
different kinds of materials, or material in two or more different states or conditions
or sizes of grain or particle, treated or mixed in the machine to be thoroughly. and
evenly mixed and rendered homogeneous throughout. For example, where
different kinds of meals, seeds, or granules, are to be mixed, and used together in
the mixed state, such material would, by a machine constructed and operating
according to this invention, be thoroughly and evenly intermixed, and rendered
homogeneous, as regards proportions of the different ingredients or grades of
material thereof, in any part of the bulk turned out.
:
.According to this invention, a mixing machine comprises a containing vessel, as
a barrel or cylinder, adapted to be revolved about an axis running longitudinally
in relation thereto, and having scoops at or near the sides thereof, and adapted to
discharge the materials when in operation at the centre of the apparatus.
In one arrangement the ends of the scoops are open, the scoops themselves at the
bottom inclining downwards and arranged on both sides of the centre, aud
terminating at or near or about and in the same vertical plane. The scoops, in
some cases, at the opposite ends of the machine may be arranged in advance of one
another.
The action of the apparatus is, that as the barrels are revolved, the scoops
carry upwards some of the material, and when they near or reach the upper part
of their circle of revolution, the material so lifted falls down out of them, into
the centre of the barrel or container, and thus the whole material is discharged
at the centre from the scoop, and becomes mixed there, and as it falls and spreads
more or less over the bottom of the containing vessel, it is again carried up by
other scoops and again discharged. This process is continued until the whole
contents of the container are thoroughly and evenly intermixed.
The revolving vessel is rotated by any suitable means, and it may be arranged
in single form, or in duplex or multiplex arrangement; and provided at convenient
parts with a filling door or filling and discharging doors.

COMPLETE SPECIFICATION.
An Improved Mixing Machine.
I, JAMES BIBBY, of Bixteth Street, Liverpool, in the County of Lancaster,
Seed Crusher, 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 has more particularly for its object to provide improved machinery

page_text: for mixing pulverulent materials, with the object, chiefly, of causing two or more
different kinds of such materials (or material in two or more different states or
conditions or sizes of particle) treated or mixed in the machine to be thoroughly
and evenly mixed and rendered homogeneous throughout. For example, where
different kinds of meals, seeds, or granules, are to be mixed, and used together in
the mixed state, such materials would, by a machine constructed and operating
according to this invention, be thoroughly and evenly intermixed, and rendered
homogeneous, as regards proportions of the different ingredients or grades of
material thereof, in any part of the bulk turned out.
According to this invention; a mixing machine comprises a containing vessel, as
a barrel or cylinder, adapted to be revolved about an axis running longitudinally
in relation thereto, and having scoops at or near the sides thereof, and adapted to
discharge the materials when in operation at the centre of the apparatus.
In one arrangement the ends of the scoops are open, the scoops themselves at
the bottom inclining downwards and arranged on both sides of the centre, and
terminating at or near same, or about and in the same vertical plane. The scoops,
in some cases, at the opposite ends of the machine may be arranged in advance of
one another.
The action of the apparatus is, that as the barrels are revolved, the internal
scoops or devices carry upwards some of the material, and when they near or reach
the upper part of their circle of revolution, the material so lifted falls down out of
them, into the centre of the barrel or container, and thus the whole material is
discharged at the centre from the scoop, and becomes mixed there, and then
spreads more or less over the containing vessel, and is again carried up by other
scoops and again discharged. This process is continued until the whole contents
of the container are thoroughly, and evenly intermixed.
The revolving vessel is rotated by any suitable means, and it may be arranged
in single form, or in duplex or multiplex arrangement, and provided at convenient
parts with a filling door or filling and discharging doors.
The invention the nature of which is above described is illustrated in the
accompanying drawings. In these drawings, Figure 1 is a longitudinal section
shewing a mixing machine in the form of a barrel, and Figure 2 is a cross section
of same at A A Figure 1.
In the drawings, a is the shell of the body of the barrel; b are the heads; and
ca shaft running through the barrel, and upon which and by which it is rotated.
d are the mixing scoops, and e is a door on the inside of the barrel which normally
covers an aperture through which the materials are introduced into it, and
discharged from it.
The scoops d are, in the barrel shewn, four in number, two at each end, and
they extend from the heads 6 of the barrel, to or near to the centre thereof,
at which end they are open. They are, as is shewn, arranged diagonally or
spirally in the barrel, to the sides of which they are attached, the closed ends
at the barrel heads leading or being in advance of the opposite or open end, as
viewed in relation to the direction of movement of the barrel, as indicated by the
drawings.
In operation, to charge the barrel, the door e is slid along its guides e¹, and
the aperture covered by it is opened; and the materials to be mixed-
-as for
instance the different ineals or powders, used in making cattle feeding cakes, as
in what are known as 66
compound" cakes-are charged into it. When the
barrel is filled to say about 3, or thereabouts, of its capacity, the door e is
closed and the barrel rotated through suitable gearing. In this rotation the
meals are carried up by the scoops d, and when they near or reach the upper
part of their circle of revolution, the materials so lifted fall down, they being
guided or carried into or towards the centre of the barrel; and all the scoops
being arranged as described, the materials are being constantly discharged into
the centre and mixed together, and then, spreading themselves out again in the
rotation of the barrel, are again carried up and discharged at the centre; and

page_text: thus by this repeated action the whole contents of the different meals are
rapidly so intermixed as to become thoroughly and evenly distributed and
rendered practically homogeneous. When so mixed, the material is discharged
from the barrel; and this is done by opening the door e and rotating the barrel,
the scoops tending now, or serving to deliver the compound meal towards the
aperture
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A mixing machine consisting of a rotatable vessel, as a barrel, having devices
or scoops inside it adapted to lift or carry up and deliver or discharge the materials
being mixed substantially as described.
:
2. The mixing machine consisting of a rotating barrel, and internal scoops, d,
arranged, constructed, and adapted to operate particularly as set forth with
reference to and shewn in the drawings.
