IMPROVEMENTS IN
" to be as
MILLS APPLICABLE FOR GRINDING ALMONDS COCOA NUTS AND THE LIKE
follows:-
This Invention consists of a vertical cylinder preferably made of tin and
perforated from the inside so that the rough edges of the holes may be on the
outside.
Surrounding this cylinder is a cone tapering towards the lower end so that a
very small annular space is left between the cylinder and the cone. The cone is
also perforated but from the outside so that the rough edges project inwardly and
face those of the cylinder. The bottom ends of both cone and cylinder are open.
The cone is held in an outer cylinder whose diameter is slightly in excess of the
largest diameter of the cone so that the latter fits easily inside the outer cylinder
the length of which is a little in excess of that of the cone. A cap or cover fits
over the bottom of the outer cylinder closing all in and serving to receive the
contents when ground. A suitable cross stay holds the different parts together
and also supports the handle which may be of any convenient form and is adapted
to revolve the inner cylinder.
The top is preferably open so that almonds & may be fed in as needed. They
enter the annular space between the inner cylinder and the cone falling by their
own weight and dropping down as they become reduced in size by the grinding
between the two sets of rough edges.
As this is by preference a cheap mill I prefer to make nearly all of it of tin.
The inner cylinder may be tapered if desired.

I WERNER THEODOR OSCHWALD of 58 City Road, in the County of Middlesex,
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 :-
Referring to the accompanying drawing which is a vertical section through the
outer casing and cone the cylinder being intact.
A is the vertical cylinder, preferably made of tin, and perforated from the inside
so that the rough edges of the holes a, may be on the outside of the cylinder. This
cylinder may be slightly tapered if desired.
Surrounding the cylinder A is a cone B tapering towards its lower end so that 1
an annular space decreasing towards the bottom is left between the cylinder and
the cone.
Cone B is likewise perforated, but this time from the outside, so that the rough
edges b project inwardly and face those of the cylinder.
The cylinder and the cone meet at their bottom ends, which are open so that it
will be seen in order that the ground contents may be collected in the receptacle D,
it must pass through the perforations a and b, thereby effectually stopping any
material improperly ground from falling into it.
The cone is held in an outer cylinder C, whose diameter is slightly in excess of
the largest diameter of the cone, so that the latter falls easily inside.
A receptacle D fits over the bottom of the outer cylinder C to receive the
contents when ground. A suitable cross piece E holds the different parts together.
This cross piece fits into slots e e¹ in cone B and cylinder C, and is firmly held by
the screw E¹.
The said cross piece E also supports the handle F, which may be of any
convenient shape, and is adapted to revolve the inner cylinder A and is supported
at its lower end in the cross piece K.
The top is preferably open so that the almonds &c may be fed in as needed.
They enter the annular space between the inner cylinder A and the cone B and
drop down as they become reduced in size and are ground between the two sets of
rough edges a and b. The helical strip G is fixed upon the cylinder A and serves
to force the almonds downwards and through the holes ab as the cylinder A
is revolved.
A bent arm such as H attached to the mill can be arranged to pass beneath a
table Land fixed to it by means of a set screw I.

page_text: 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,
1. In a mill such as described the combination with a perforated cone such as B
of a perforated cylinder such as A adapted to be revolved within B and fitting close
against the inner periphery of B at the lower end for the purpose of preventing
the passage of lumps substantially as specified.
2. In a mill such as described the combination with the grinding cylinder A and
cone B of a helical strip such as G for the purpose of forcing down the material
which is being ground substantially as specified.
