PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Whole Meal.
I, WILLIAM WIDDISON of Iccles Mills, Rotherham in the County of York, Miller
do hereby declare the nature of this invention to be as follows:-
My Invention refers particularly to the manufacture of whole wheat meal, the
object being to produce a meal combining all the nutritive properties of the wheat, in
particles of more uniform size than has heretofore been accomplished and consequently
in a form which renders it easier to digest when it is made into bread than when the
particles and more especially in reference to the particles of the cortex, which are
usually left of larger size than those of the other parts of the grain.
To accomplish this object, I crush or grind the wheat preferably between a pair of
French Stones, from which it runs into and is carried forward by a screw carrier (or
like means) to an elevator.
The elevator raises it and passes it forward to a dressing reel or sieve of suitable
mesh; all the meal or flour passing through mesh of the reel or sieve falls down a
shoot to the sack or store bin, but the coarser parts cannot pass through, and which
consist chiefly of cortex, pass out at the end of the reel, and are carried by a shoot to
another or second pair of stones by which the particles are further ground and
reduced to the required size-the shoot from this pair of stones runs the reground
material into the screw carrier mixing it with the meal from the first pair of stones
with which it is again passed into the sieve or reel. Although I prefer to use French
Stones for this purpose I do not bind myself to such use, as other grinders such as
rolls or discs may be employed if preferred.

Improvements in the Manufacture of Whole Meal.
1, WILLIAM WIDDISON of Iccles Mills, Rotherham, in the County of York, Miller
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 relates particularly to the manufacture of whole wheat meal, the
object being to produce a meal combining all the nutritive properties of the wheat,
and in particles of more uniform size than has heretofore been accomplished, and
consequently in a form which enables it to be more easily digested when made into
bread, than when such particles vary in size, having referance especially to the
particles of the cortex, which are usually left larger than those of the softer parts of
the grain. To enable my invention, and the process by which it is carried into
effect, to be understood I have annexed a diagram illustrative of such process, but I
wish it to be understood that I do not bind myself to the exact arrangement shown,
as such may be varied without departing from the spirit of the invention.
I crush or grind the wheat preferably between one or more sets of French Stoņes A,
supplying them in the usual manner from a garner B, or other similor storage places.
From the stones A, the ground meal runs into a screw traveller C, or other
equivalent means of carrying the meal to an elevator D.
The elevator D passes it forward to sieve or dressing reel E, of suitable mesh, and
all the meal which passes through the sieve or reel, is of the required size and is
carried down the shoot F, to the sack (or store bin) S.

page_text: The coarser parts, amongst which the greater proportion is cortex, are expelled out
of the end of the reel or sieve,. and fall down the shoot G to a second pair or series of
stones H, by which the particles are reground and reduced to the required size,
passed through shoot I into the traveller C, up the elevator D, through the reel or
sieve E, to the sack S.
If there remain any obstinate particles of the cortex, that still remain too large to
pass.through the mesh of the reel they pass round through the same process until
they are reduced to the required size.
Although I prefer to use French Stones for the purpose of this invention, I do-not
bind myself to such use, as other grinding machinery such as rolls, or discs, may be
satisfactorily employed instead of stones, and the situation of the various machines
and apparatus shown in the diagram may be varied as will be well understood.by
practical men.
.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that what I
claim, is :-
In the manufacture of whole-wheat meal, causing the larger particles of the first
ground meal that will not pass the dressing reel, to be automatically separated and
carried to a second pair of stones, (or other grinder,) from which the reground
particles are carried with the meal issuing from the first stones or other grinder, and
are again passed into the dressing reel; the said process being repeated, until all the
particles can pass through the mesh of the reel, substantially in the manner as is
herein before described and shown.
