page_text: I WILHELM BAUER of San Carlos in the Province of Santa Fé, Argentine
Republic, do hereby declare the nature of this Invention to be as follows:-
It has been observed in roller mills that only a part of the meal falls down
whilst the remainder which is the better quality is thrown to one side by the
cylinders or adheres to them.
This fact has been utilized for the purpose of dividing the meal into two or
more qualities.
The invention consists in a casing for the cylinders provided with hoppers or
receptacles beneath the cylinder to receive the different grades, said receptacles
being separated from one another by longitudinal partitions which may be adjusted
to vary the proportion of the product falling into the different hoppers or recep-
tacles there being a central longitudinal hopper or receptacle immediately beneath
the bite of the rollers to receive the product directly falling therefrom and at each
side thereof one or more other receptacles to receive the product which is carried
partly round by the cylinders against which are applied scrapers or brushes to
prevent the finer product being carried thrice through the cylinders.

page_text: I, WILHELM BAUER of San Carlos in the Province of Santa Fé, Argentine
Republic, 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 :-
It has been observed in roller-mills that only a part of the meal falls down
whilst the remainder, which is the better quality, is thrown to one side by the
cylinders or adheres to them. This fact is utilized for the purpose of dividing
the meal into two or more qualities.
The Invention is illustrated in the accompanying drawing which represents a
vertical section of the arrangement. 6b are the cylinders enclosed in a casing,
provided with a central longitudinal hopper c and with one or more hoppers or recep-
tacles g placed on either side thereof beneath the cylinders to receive the different
grades of meal, said receptacles being separated from one another by longitudinal
partitions or flaps f hinged at h in order that they may be adjusted to vary the
proportion of the product falling into the different hoppers or receptacles. The
central longitudinal hopper or receptacle c immediately beneath the bite of the
rollers receives the product directly falling therefrom, while the receptacles g
receive the product which is carried partly round by the cylinders. At the sides
of the cylinders are applied scrapers d or brushes to prevent the finer product
being carried again through the cylinders. An opening a is provided at the top of
the casing immediately above the bite of the cylinders for the introduction of the
material to be reduced.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed; I declare that what
I claim is ;-
1at The combination with a roller mill of an arrangement by means of which
the material after having passed the rollers is separated according to its quality,
consisting of the hoppers or receptacles g situated below the rollers 6 and serving
to receive the different grades of the product falling from or scraped off the same.
2nd The arrangement of adjustable flaps f f which can be regulated so as to
vary the proportion of the product falling into the different hoppers or receptacles.
3rd In a roller mill, the arrangement of scrapers or brushes d towards the outer
sides of the rollers in combination with hoppers arranged as described whereby
the material which falls at once from the rollers is kept separated from that which
adheres thereto and the material is consequently graded according to quality All
substantially in the manner and for the purpose as described and shown in the
drawing.
