PROVISIONAL SPECIFICATION.
Improvements in Edge Pan Runners for Grinding Clay and the like.
We, ARTHUR SABINE and TIMOTHY SABINE, of The Vulcan Works, Swadlincote,
in the County of Derby, Engineers, do hereby declare the nature of this invention
to be as follows:-
runners SO
replaced.
Our invention relates to an improved method of constructing edge pan
as admit of the parts most subject to hard wear being readily
These runners or grinding wheels have heretofore been generally cast either
in one piece with the boss or sometimes have had a removable outer cover fitted
on the outer flange; but as far as we are aware the outer cover or actual grinding
rim has always been cast or made of one piece of metal.
In carrying out our invention we form this outer grinding rim of a number
of segments of any suitable form either with straight, oblique or other suitable
joints and bolt them through and to a flange or rim connected to or cast with
the boss in the usual way, the bolt heads or nuts may be counter sunk or recessed
in the segments of the grinding rim in any well known manner.
By adopting this method of building up a grinding wheel or runner the parts
of the grinding rim may be of an inferior or harder metal than the other parts
of the wheel and as will be readily understood the segments may be easily taken
off and replaced when worn without disturbing the other parts of the apparatus
or machine.

Improvements in Edge Pan Runners for Grinding Clay and the like.
We, ARTHUR SABINE and TIMOTHY SABINE, of The Vulcan Works, Swadlincote,
in the County of Derby, Engineers, 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 invention relates lo an improved method of constructing edge pan
runners so as to admit of the parts most subject to hard wear being readily
replaced.
These runners or grinding wheels have heretofore been generally cast either
in one piece with the boss, or, sometimes have had a removable outer cover fitted
[Price Sd

rim has always been cast or made of one piece of metal.
In describing our invention reference will be had to the accompanying sheet
of drawings upon which Figures 1 and 2 are side and end elevations respectively
of an edge pan runner or grinding wheel constructed according to our invention.
Figure 3 is an enlarged section on line aa of Figure 2.
In carrying out our invention we form this outer grinding rim of a number of
segments A of any suitable form, either with straight, oblique or other suitable
joints and bolt them through and to a flange or rim. B connected to or cast with
the boss in the usual way, the bolt heads C may be counter-sunk or recessed in
the segments of the grinding rim in any well known manner.
By adopting this method of building up a grinding wheel or runner, the parts
of the grinding rim may be of an inferior or harder metal than the other parts
of the wheel, and as will be readily understood, the segments may. be easily
taken off and turned about or replaced when worn without disturbing the other
parts of the apparatus of machine.
We do not wish to bind ourselves to any particular form of segment or of
fixing same to the body of the wheel as this will necessarily be varied to suit
individual requirements and conditions.
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, grinding mills, the building up of the outer grinding rims of the runners
or grinding wheels in removable sections, substantially as described and illus-
trated.
