AN IMPROVEMENT IN THREE-HIGH ROLLER MILLS FOR TREATING CEREALS
Year: 1884

page_text: I, JOHN IMRAY of No 28 Southampton Buildings, Chancery Lane, in the County
of Middlesex, Consulting Engineer and Patent Agent do hereby declare the nature
of my invention for "AN IMPROVEMENT IN THREE-HIGH ROLLER MILLS FOR
TREATING CEREALS" to be as follows:-
My invention relates to that kind of roller mill for treating cereals, which has
three rollers in height, the feeds being so arranged that a portion of the material
operated on passes between the highest and the middle rollers and a portion
between the middle and the lowest rollers. The latter portion on its way from the
feed hopper to the lower nip has to pass through the stream of material discharged
from the upper nip, and for this purpose a number of feed channels somewhat
separated from each other are provided, through which the material descends. It
is found however that owing to its aggregation in these channels, the material is
not in all cases equably distributed between the rollers, those parts of the rollers
which face the channels being sometimes more or less overloaded, while the parts
between receive too little feed. My invention has for its object to provide against
this, and to secure in a simple manner an equable distribution of the material over
the whole length of the nip between the middle and the lowest rollers. For this
purpose, I arrange opposite to and at some distance from the mouths of the cross_
feed channels above mentioned, a concave or flat strip of plate which extends the
whole length of the feed cavity and acts as a reflector causing the material which
streams on it from the separate feed channels to spread itself out sideways and
lengthways so as to descend in an even layer along the sloping feed plate and so to
enter the nip of the rollers in uniform distribution along their whole length.

I, JOHN IMRAY of N° 28 Southampton Buildings, Chancery Lane in the County
of Middlesex Consulting Engineer and Patent Agent do hereby declare the nature
of my invention for "AN IMPROVEMENT IN THREE-HIGH ROLLER MILLS FOR
TREATING CEREALS" 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 to that kind of roller mill for treating cereals, which has
three rollers in height, the feeds being so arranged that a portion of the material
operated upon passes between the highest and the middle rollers and a portion
between the middle and the lowest rollers. The latter portion on its way from the
feed hopper to the lower nip has to pass through the stream of material discharged
from the upper nip, and for this purpose a number of feed channels somewhat
separated from each other are provided, through which the material descends. It
is found however that owing to its aggregation in these channels, the material is
not in all cases equally distributed between the rollers, those parts of the rollers
which face the channels being sometimes more or less overloaded, while the parts
between receive too little feed. My invention has for its object to provide against
this, and to secure in a simple manner an equable distribution of the material over
the whole length of the nip between the middle and the lowest rollers. For this
purpose, I arrange opposite to and at some distance from the mouths of the cross
feed channels above mentioned, a concave convex or flat strip of plate which
extends the whole length of the feed cavity and acts as a reflector causing the
material which streams on it from the separate feed channels to spread itself out
sideways and lengthways so as to descend in an even layer along the sloping feed
plate and so to enter the nip of the rollers in uniform distribution along their
whole length.
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
In combination with the cross feed channels of three-high roller mills, the use of
a distributing or reflecting plate so arranged that the material falling upon it from
the said channels shall be more or less evenly distributed over the feed plate to the
lower nip.
