I, ALFRED CHAPMAN, of 17, York Street, Liverpool, in the County of Lancaster,.
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to machines for washing coffee berries; and it com-
prises, mainly, a feed case and container for the berries, and a horizontally.
disposed washing wheel having a spiral way or ways extending from the centre,
and in which, the feed or supply to it takes place at the centre, and the discharge.
is at the periphery.
According to one construction or form under this invention, the container
box or case, has, extending through it, a sleeve, constituting the hearing for
the wheel shaft, which, preferably, is hollow, and the supply or opening for the
passage of the berries from the container to the central portion of the wheel,
takes place through openings or ports in the end plate of the case, next the
wheel, and directly around the sleeve, the case or box being so formed as to
induce the movement of the berries towards these ports or openings.
The end plate of the case or container, over which the inside surface of the
wheel works, is circular. and of slightly less diameter than the wheel; and there
is provided, in connection with it, an annular chamber extending inwards
laterally, and at the bottom of this chamber, an outlet, which may be provided
when a weighted flap door, is provided.
The wheel consists of a disc at one side, riz., the outside, a flange extending
inwards from the periphery of the disc, and a spirally arranged row or rows of
pegs, standing from about the centre to the periphery, these pegs being spaced
so as to prevent berries from passing between them, but to admit of the flow
of water. At the central part of the wheel, which comes opposite the feed or
supply ports, it is provided with tangential curved arms.
In action, the machine being supplied with berries and water, and the wheel
revolved by hand or power, the berries pass from the container or supply case,
through the central ports or openings in the end plate, to the spaces within the
tangential plates of the wheel and from this point they pass directly to the
spiral space or way formed by the pegs above described.
Through this space they pass in a continuous sriral course to the periphery
of the wheel, riz., the weh, where they are stopped in their radial movement;
and from this part they rass into the annular chamber in the face of it, and so
to the outlet of the machine.

I, ALFRED CHAPMAN, of 17, York Street, Liverpool, in the County of Lancaster,
Engineer, 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 machines for washing coffee berries; and it comprises,
mainly, a feed case and container for the berries, and a washing wheel having a
spiral way or ways extending from the centre, and in which the feed or supply
to it takes place at the centre, and the discharge is at the periphery.
According to one construction or form under this invention, the container
box or case, has, extending through it, a sleeve, .constituting the bearing for
the wheel shaft, which, preferably, is hollow, and the supply or opening for the
passage of the berries from the container to the central portion of the wheel,
takes place through openings or parts in the end plate of the case, next the
wheel, and directly around the sleeve, the case or box being so formed as to
induce the movement of the berries towards these ports or openings.
The end plate of the case or container, over which the inside surface of the
wheel works, is circular, and of slightly less diameter than the wheel; and there
is provided, in connection with it, an annular chamber extending inwards
laterally and. at the bottom of this chamber, an outlet, which may be provided
with a weighted flap door, is provide:.
;
The wheel consists of a disc at one side, viz., the outside, a flange extending
inwards from the periphery of the dise, and a spirally arranged row or rows of
pegs, standing from about the centre to the periphery. At the central part of
the wheel, which comes opposite the feed or supply ports, it is provided with
tangential curved arms.
In action, the machine being supplied with berries and water, and the wheel
revolved by hand or power, the berries pass from the container or supply case,
through the central ports or openings in the end plate, to the spaces, within the
tangential plates of the wheel; and from this point they pass directly to the
spiral space or way formed by the pegs above described.
Through this space they pass in a continuous spiral course to the periphery
of the wheel, viz., the web, where they are stopped in their radial movement;
and from this part they pass into the annular chamber in the face of it, and so
to the outlet of the machine.
In the drawings illustrating this invention, Figures 1, 2, and 3, shew a coffer
washing machine in two end elevations, and in side elevation, respectively.
Figure 4 is a side elevation shewing the body of the washer with some parts
removed and Figure 5 is an elevation in section through the centre of the
machine with the washing wheel removed. Figures 6 and 7 shew views of the
machine from underneath and above. Figure 8 shews an inside view of the disc
or wheel and a transverse section.
Referring to the drawings, a is the container box or case of the machine, having
a sleeve extending through it, and constituting the bearing for the shaft of
the pegged disc. c is an annular opening in the end plate c¹ of the box a round
the end of the sleeve b, through which the berries pass from the chamber a¹ to
the disc or wheel, d is an annular trough, concentric to the axis of the machine,
within which the wheel or pegged disc is disposed and revolved and is an
extension of this chamber inwards laterally. In the bottom of this chamber
is an outlet provided with a hinged weighted flat door e. g is a lubricating
tube.

page_text: The wheel or disc which is generally designated h, consists of a disc i at one
side, viz., the outside, a flange j extending inward from the periphery, and a
spirally arranged row of pegs k on the disc i, said disc being provided with a
handle h¹. A hollow shaft is formed on the disc, which revolves in the sleeve b,
and within the disc around the shaft tangentially curved arms m are provided,
these arms being opposite the annular opening c.
-
A crank turning wheel o is fixed on the opposite end of the shaft to the wheel h;
and a handle o is provided on this wheel.
In action, the wheel being supplied with berries and water, and the wheel h
revolved, the berries pass from the vessel a', through the annular opening c, into
the centre part of the disc h within the tangential arms m. From this part they
pass to the spiral way formed by the pegs k, by the action of rotation of the
disc to the periphery. When the berries arrive at the periphery of the wheel,
viz., the web or flange, they pass from this part into the chambers and so
to d: whence they are di charged through the door e. By this action, and mode
of conveying the berries through the disc with the water, they are thoroughly
cleansed.
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 coffee washing machine comprising a body, and a disc or wheel having
pegs or equivalent provisions upon its inner face, and to the centre of which the
coffee berries are introduced, and by which they are moved centrifugally through
the disc, and operated upon by such movement: substantially as and for the
purposes set forth.
2. In a coffee washing machine, a containing chamber a¹; a central sleeve b;
an opening c from the chamber a¹; a wheel or disc h with pegs on its inner
face; and a chamber (dd) round the periphery of the wheel or disc; substantially
as and for the purposes set forth.
3. In a coffee washing machine, a wheel or disc h, constructed and adapted to
operate as set forth with reference to and shewn in the drawings.
4. A coffee washing machine, having its parts arranged constructed, and
adapted to operate, particularly as set forth with reference to and shewn in the
drawings.
