PROVISIONAL SPECIFICATION.
Improvements in Sorting-plates for Cereals.
I, NICOLAUS HEID, of Stockerau, Lower Austria, Engineer and Manufacturer,
do hereby declare the nature of this invention to be as follows:-
The sorting-plates that serve to sort the spherical seeds of weeds from the
oblong grains of cereals are for this purpose made with recesses or cells of suitable
form and size for receiving the spherical seeds, such recesses or cells being
produced of a cup or reticulated shape either by stamping or punching or by
cutting with boring tools. Those formed by stamping or punching have the
defect that the recesses or cells require to be at comparatively large distances apart
and that their edges are rounded.
Those formed by means of drills or boring tools, (which process was adopted in
order to avoid the above defects) on the other hand offer the disadvantage that
the boring tool does not produce reticulated cells, but cells of hemispherical form,
which form has been proved to be less efficaceous in working.
According to my present invention I produce the cells or recesses of a cup
shape or reticulated form by cutting them by means of rose cutters, thus affording
the recesses the advantageous form produced by stamping or punching, while they
can be placed closely together and made with sharp edges.
The accompanying drawing shews a section of a sorting plate in which the cells
or recesses are formed by rose cutters so as to have a reticulated form according
to my present invention.
Dated this 7th day of April 1894.

I, NICOLAUS HEID, of Stockerau, Lower Austria, Engineer and Manufacturer,
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 :-
The sorting plates that serve to sort the spherical seeds of weeds from the
oblong grains of cereals are, for this purpose made with recesses or cells of suitable
form and size for receiving the spherical seeds, such recesses or cells being produced
of a cup or reticulated shape either by stamping or punching or by cutting with

Those formed by stamping or punching have the defect that the recesses
or cells require to be at comparatively large distances apart and that their edges
are rounded.
Those formed by means of drills or boring tools, which process was adopted in

above described so as to have a reticulated form according to my present
invention.
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 :-
Sorting plates for cereals having reticulated or cup shaped recesses formed by
cutting tools as herein described and shewn on the drawing.
