I, GEORGE SHAW RICHMOND, of Llanelly, in the County of Carmarthen, Engineer,
do hereby declare the nature of this invention to be as follows:-
This Invention relates to Corn Grinding Mills, having Metal Rollers and Metal
Grinding Surfaces.
The first part of this Invention relates to those Mills having a parallel and fluted
Roller working against a fixed and fluted Concave.
And also to those Mills having two parallel Rollers working together in opposite
directions and between which the grain is ground.
The second part of this Invention relates to those Mills having a fluted Conical
Roller working inside a fluted Conical Cylinder.
The objects of this Invention are
To simplify the construction.
To make the Mills more efficient and to enable the wearing parts to be removed
more easily and at less cost than heretofore.
In carrying out my Invention as applied to Mills with parallel Rollers, I make a
Metal Ring, preferably of Cast Steel having an internal flange made in one piece with
the Ring which forms the Roller, this internal flange I carefully bore and face and
afterwards bolt on to a Disc which is firmly keyed on the central spindle, by taking
out these bolts, the Ring which forms the Roller is easily removed.
In carrying out the second part of my Invention as applied to Mills having a
fluted Conical Roller working inside a fluted Conical Cylinder. In like manner I
make a Metal Conical Ring fluted on the outside and having an internal flange made
in one piece with the Conical Ring, which forms the Roller. This internal flange I
carefully bore and face, and afterwards bolt on to a Disc which is firmly keyed on the
central spindle by taking out these bolts the Conical Ring which forms the Roller is
easily removed.
Dated this First day of February 1888.

page_text: The first part of this Invention relates to those Mills having a paralell and fluted
Roller working against a fixed and fluted concave and also to those Mills having
two paralell Rollers working together in opposite directions between which the Corn
is ground.
The second part of this Invention relates to Mills having a fluted Conical Roller,
working inside a fluted Conical Cylinder.
The objects of this Invention are
To simplify the Construction of the Rollers.
To make the Mills more efficient and to enable the wearing parts to be more easily
removed and renewed at less cost than heretofore.
In carrying out my Invention as applied to Mills with paralell Rollers, I make a
Metal Ring preferably of Cast Steel, having an internal flange, made in one piece with
the ring, which forms the roller, this internal flange I carefully bore and face and
afterwards bolt on to a disc which is firmly keyed on the central spindle. By taking
out these bolts, the flanged ring which forms the roller is casily removed.
In carrying out the second part of my Invention as applied to Mills having
a fluted conical roller working inside a fluted Conical Cylinder. In similar
manner I make a Metal Conical ring fluted on the outside and having an internal.
flange cast or made in one piece with the Conical Ring. This internal flange
1 carefully bore and face, and afterwards bolt on to a disc or bush which is
firmly keyed on the central spindle. By taking out these bolts the Conical Ring
which forms the roller is more easily removed than as hitherto made.
In order that my Invention may be clearly-understood and readily carried into
effect, I will proceed to describe same with the aid of the accompanying Drawings.
Figure 1 is a sectional elevation of the paralell Roller complete A being the Metal
Ring A 1 the internal Flange B is the Disc which is keyed on the spindle C.
Figure 2 is a plan of same.
Figure 3 is a sectional elevation of the Conical Roller A being the Conical Ring
A 1 the internal Flange B is the Disc or Bush which is keyed on the spindle C.
Figure 4 is a plan of same.

page_text: 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
1st. A paralell metal ring having an internal flange made in one piece with
the ring substantially and for the purposes set forth.
2nd. A Conical Metal ring having an internal flange made in one piece with
the ring substantially and for the purposes set forth.
In witness whereof I the said George Shaw Richmond have hereunto set my
band and seal this 11th day of May in the year of our Lord One thousand
Eight hundred and Eighty eight.
GEORGE SHAW RICHMOND.
