PROVISIONAL SPECIFICATION.
Improvements in or appertaining to Centrifugal Separating or
Dressing Machines, especially applicable to the Separating or
Dressing of Flour, Middlings, Grain, Seeds, or the like.
I, JAMES HIGGINBOTTOM of 32 Seel Street Liverpool, in the County of
Lancaster, Milling Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to certain improvements applicable to the inventions
described in my Patent No. 6370 of 1889 and in my application for Letters Patent
No. 18306 of 1890. In working the above mentioned inventions, I find that when
the machines are dealing with bulky materials such as the bran from wheat and
when a sudden influx of feed is accidentally admitted into the cylinder, such sudden
excess of feed has a tendency to become compressed or choked between the
deflecting face of the deflector and the impact or striking face of the beater,
thereby causing an increase in the driving power or even a stoppage of the
machine.
The object of this invention is to so devise the deflectors and beaters in relation
to each other that any sudden influx of feed over and above the normal rate of feed
shall be enabled to pass through the machine without causing any choking or
stoppage of the machine.
In carrying out my invention, I use the deflectors as described in the before-
mentioned Patents, and I make the beaters with very short impact or striking
faces, in such manner that there is no space contained between the deflecting face
of the deficctor and the impact or striking face of the beater. I also combine
therewith the vanes as described in my Patent application No. 18306 of 1890.
Dated this 23rd day of July 1891.

COMPLETE SPECIFICATION.
Improvements in or appertaining to Centrifugal Separating or
Dressing Machines, especially applicable to the Separating or
Dressing of Flour, Middlings, Grain, Seeds, or the like.
I, JAMES HIGGINBOTTOM, of 32, Seel Street, Liverpool, in the County of
Lancaster, Milling Engineer, 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 :-
This invention relates to certain improvements applicable to the inventions
described in the Specifications of my Letters Patent No. 6370 of 1889 and
No. 18306 of 1890.
In working the above mentioned inventions, I find that when the machines are
dealing with bulky materials such as the bran from wheat, and when a sudden influx
of feed is accidentally admitted into the cylinder, such sudden excess of feed has a
tendency to become compressed or choked between the deflecting face of the
deflector and the impact or striking face of the beater, thereby causing an increase
in the driving power or even a stoppage of the machine.
The object of this invention is to so devise the deflectors and beaters in relation
to each other, that any sudden influx of feed over and above the normal rate of

page_text: feed shall be enabled to pass through the machine without causing any choking or
stoppage of the machine.
In carrying out my invention, 1 use the deflectors as described in the before
mentioned Patents, and I make the beaters with very short impact or striking faces,
in such manner that there is no space contained between the deflecting face of the
deflector and the impact or striking face of the beater capable of holding material
fast therein. I also combine therewith the vanes as described in my Specification
aforesaid, No. 18306 of 1890.
Referring to the drawings-
Figure 1 is a part view of the beater wheel,
Figure 2 an enlarged end view of beaters.
Figure 3 a side view of part shown in Figure 2, and
Figure 4 a plan view of part shown in Figures 2 and 3.
In these, E is the deflector, and B is the beater.
The space occupied by the arrow is for the material to pass through in case of a
surfeit. FF are small vanes, and G G large ones, the latter carrying the deflector
and beater and uniting them with the arms C³. The remaining letters on the
drawing are the same as those in my former Specifications.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
--
1. The improvement on my former inventions as set forth in my Patents
No. 6370 of 1889 and No. 18306 of 1890 whereby, if any sudden influx of feed
occurs, the surplus can pass through the machine without causing a choking or
stoppage thereof.
2. The combination of parts E B and F substantially as and for the purposes
hereinbefore described in so far as they differ from my before mentioned inventions
and for the purposes specified.
