Edge-runner Grinding Mill for Powdering Marls, Bones, Cement,
Slags, and other Materials.
JOSEPH ONIONS, 81, Wanderers Avenue, Dudley Road, Wolverhampton, Stafford-
shire, Brick Manufacturer, do hereby declare the nature of this invention to be as
follows:-
---
That the clay is sieved first in the revolving pan in which it is ground, falls
through into a second perforated stationary pan, directly under revolving pan,
and after the fine clay fall through this stationary pan, it drops into a funnel,
thence is conveyed by a trough into the elevators, whilst the rough clay in this
stationary pan is propelled by scrapers through a hole in the side of the pan into
small elevators by which it is conveyed to the grinding pan again.

Edge-runner Grinding Mill for Powdering Marls, Bones, Cement,
Slags, and other Materials.
I, JOSEPH ONIONS, of 81, Wanderers Avenue, Dudley Road, Wolverhampton,
in the County of Stafford, Brick Manufacturer, 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:-
My invention has for its object an improved edge-runner grinding mill for
grinding or powdering marls bones cement slags &c. by which the clay or other
material is more thoroughly and quickley ground and separated than hithertofore
while a considerable amount of labour is saved by the arrangement of the pans
and hopper for transferring the fine clay to the elevators.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a sheet of drawings upon which
Figure 1 is a part sectional elevation through one of my edge-runners.
In carrying my invention into effect the clay or other material is sieved first in
the revolving pan A in which it is ground by the runners C after which it passes
through the holes a¹ formed in the pan A and falls into the second perforated
stationary pan B where it is propelled by scrapers D the fine clay falling through
the perforations b¹ into a hopper or funnel indicated by dotted lines E from whence

page_text: it is conveyed by a trough to the elevators while the rough clay in the stationary
pan B is propelled by the scrapers D until it passes through a hole in the side of
the pan into small elevators by which it is conveyed to the grinding pan A again.
The mill is mounted on girders F to which the hopper or funnel E is secured
and by which means the fine clay is more easily conveyed to the elevators.
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
1st. In edge runner grinding mills for grinding or powdering marls bones,
cement slags and other similar material the perforated revolving pan A in com-
bination with a perforated stationary pan B substantially as and for the purpose
herein set forth and illustrated.
2nd. In combination with Claim 1 the mill mounted on girders F with hopper E
for conveying the fine material to the elevators substantially as herein set forth
and illustrated.
