We, ALEXANDER WILLIAM GILLMAN, SAMUEL SPENCER and ERNEST SAMUEL
SPENCER all of the Castle Brewery, St. George's Road, Southwark in the County
of Surrey, Consulting Practical Brewers, and Analytical Chemists do hereby declare
the nature of said invention to be as follows:-
Our present invention has for its object improvements in machinery or apparatus
employed in treating grain according to the process described in the specification
of Letters Patent granted to us dated January 6, 1885, No. 211.
In the above mentioned specification we describe a process of rolling or flattening
grain or cereals after they have been treated according to the process described in
the specification of Letters Patent granted to us dated January 26, 1881 No. 344.
In carrying out this rolling or flattening process we find it necessary to employ
a doctor or scraper to free the grain or cereals from the rolls. Hitherto we have
employed a single doctor or scraper to each roll and in order to ensure the freeing
of the roll we have found it necessary to press this doctor or scraper with
considerable force against the roll. This has had the effect of wearing away the
doctor or scraper and the rolls sometimes unequally and of increasing the power
required to drive the rolls.
Now by our present invention we avoid these difficulties. This we effect in the
following manner. We employ two scrapers or doctors to each roll, which two
scrapers or doctors are fixed to the same carrier or carriers so that they shall act
upon the roll at a suitable distance apart from each other. Each carrier or set of
carriers is carried at its centre by an arm which is provided with adjusting means
so arranged as to enable the scrapers or doctors to be adjusted close to the surface
of the roll and there held without pressing them forcibly against the roll. They
are also capable of rocking slightly on their support so that in the event of one of
them being forced somewhat away from the roll the other will be more tightly
pressed against the same.

We ALEXANDER WILLIAM GILLMAN SAMUEL SPENCER, and ERNEST SAMUEL
SPENCER, all of the Castle Brewery St. George's Road, Southwark in the County
of Surrey Consulting Practical Brewers and Analytical Chemists 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 :-
Our present invention has for its object improvements in machinery or apparatus
employed in treating grain according to the process described in the specification
of Letters Patent granted to two of us dated January 6, 1886 No. 211.
In the accompanying drawings Figure 1 is a front view and Figure 2 is
a sectional end view of parts of a mill showing our improvements applied
thereto.
In the above mentioned specification we describe a process of rolling or flattening
grain or cereals after they have been treated according to the process described in
the specification of Letters Patent granted to two of us dated January 26, 1881
No. 344.
In carrying out this rolling or flattening process we find it necessary to employ
a doctor or scraper to free the grain or cereals from the rolls.
Hitherto we have employed a single doctor or scraper to each roll and in order
to ensure the freeing of the roll we have found it necessary to press this.doctor or
scraper with considerable force against the roll.
This has had the effect of wearing away the doctor or scraper and the rolls,
sometimes unequally and of increasing the power required to drive the rolls.
Now by our present invention we avoid these difficulties. This we effect in the
following manner. We employ two scrapers or doctors b, 61, to each roll a which
two doctors or scrapers b, b¹ are fixed to the same carrier or carriers c so that they
shall act upon the roll at a suitable distance apart from each other.
Each carrier or set of carriers c'is carried at its centre by an axis c¹, or it may
be by an arm, which is mounted at its ends in blocks d fitted to work in bearings 6
carried by the frame of the machine and which blocks d are acted upon by
adjusting screws f, f, in such manner as to enable the scrapers or doctors b, b', to
be adjusted close to the surface of the roll a and there held without pressing them
too forcibly against the roll. The doctors or scrapers 66 are also capable of
rocking slightly on their support or axis c¹ so that in the event of one of them
being forced somewhat away from the roll a the other will be more tightly pressed
against the same.
Other suitable and convenient arrangements may however be adopted for
carrying and adjusting the pair of doctors or scrapers 66¹ so long as they are
capable of adjustment to the rolls substantially as above described.
In the drawings we have only shown one of a pair of rolls a and its
accompanying doctors or scrapers b, b², the other roll and its accompanying
doctors or scrapers are of precisely similar character.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
.
In machinery or apparatus employed in treating grain or cereals to be used in
brewing, distilling and vinegar making, the employment of a pair of adjustable
doctors or scrapers to each roll, substantially as herein shown and described and
for the purpose stated.
