Specification Accepted, 27th July, 1888
and the like.
I, WERNER THEODOR OSCHWALD, of 262, Goswell 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 :-
This invention relates to improvements in the construction of the mill described in
the Specification of my Letters Patent No. 8,242 of 1885.
In using mills constructed according to the specification of my said patent it has
been found that portions of the partially ground almonds or other nuts were forced
through the perforations of the cone which surrounded the cylinder, and that as a
consequence it has been found impossible to grind the nuts so finely as is required
for some purposes.
My improvements consist in employing a plain or unperforated cone in place of the
perforated cone as described in ny said specification; also in employing division
strips on the interior of the cone for preventing the nuts which are being ground from
being rotated with the grinding cylinder.
In the accompanying drawing
Figure 1 is an elevation of my improved mill.
Figure 2 is a vertical section of the same, and
Figure 3 is a plan.
A is the vertical grinding cylinder the sides of which are perforated from the
inside, as shown in figure 2 of the drawing, and which can be somewhat tapered if
desired. B is the cone which I make plain or unperforated, as shown in the said
figure 2, the cone being formed taper so as to leave an annular space (decreasing
towards the bottom) between the grinding cylinder A and the cone B, the sides of
the said cylinder and cone meeting at their open bottom ends; h, h are the division
strips which I employ on the interior of the cone B for preventing the almonds or
the like which are being ground from rotating with the grinding cylinder A. The
division strips are placed in a slightly helical direction to cause the substances to be
carried downwards and through the holes a, a in the cylinder as it revolves.

receptacle D.
Cis the outer casing in which my plain or unperforated cone B is hold. Tho
receptaclo D is adapted to be slid under the casing O. E is the cross piece for holding
the various paris together, one end being passed into tho slots e and e in the cone B and
outer cylinder respectively and the other end being fixed by a nut Escrowing onto
n threaded pini on the casing C, the said pin passing through a slot in the turnod
down end of the cross piece E. Fis the handle fitted on the upper end of the square
spindle, which spindle passes through the cross piece E and its lower and works
in the cross piece K. The said handle is adapted to revolve the grinding cylinder A
by means of the spindle. H is the bent arm attached to the mill and arranged to
pass beneath a table L or the like and to be fixed thereto by means of a set screw I.
The almonds or the like to be ground are introduced through the open top of the
mill into the space between the grinding cylinder A. and the plain or unperforated
cone B. The handle F is then turned and the almonds held by the division strips k, h
will be ground by the rotating cylinder A, the ground product being carried through
the perforations a, a in the grinding cylinder in order to reach the receptacle 1) froin
which the said product can then be removed by withdrawing the receptacle from
under the casing C.
It will bo obvious that, where necessary, in consequence of the size of the mill,
bevel gearing driven by power can be employed for rotating the spindle of thu
grinding cylinder A instead of a handle as described and shown.
Having now particularly described and ascorfained the nature of my said inven
tion and in what manner the same is to be performed, 1 declare that what 1
claim is :-
1. In a mill of the kind hereinbefore described, the use of a plain or unperforated
cone such as B, and of division strips fixed on the interior of the same, substantially
as aud for the purpose setforth.
2. The improved mill applicable for grinding almonds, cocoa-nuts, and the like
hereinbefore described and illustrated in the accompanying drawing.
