PROVISIONAL SPECIFICATION.
Improvement in Arrangement of Mills for Grinding Cement,
Phosphates, and other Substances.
We WILLIAM FREDRICK GOREHAM of 22 Erskine Road South Shields in the
County of Durham, Cement Works Manager and MICHAEL WATSON of 82 Rye
Hill in the City and County of Newcastle upon Tyne Engineer do hereby declare the
nature of this invention to be as follows:-
Generally the arrangement for driving mill stones consists of a lay shaft running
underneath them the motion being transmitted by hevilled gearing the floor on
which the stones are placed being necessarily raised to allow room for this gearing.
The material to be ground is raised by elevators to a bin or hopper placed overhead
& fed from thence to the stones.
Our arrangement consists of placing the stones at or about the ground level,
driven by lay shaft running overhead, (carried by girders) through suitable
gearing.
The vertical spindle is made so as to be readily disconnected above the stone to
allow of the latter being lifted, the bottom running in suitable bearing adjustable
or otherwise and carried preferably by the bedstone.
The hopper is placed at one side of the stones preferably at the outside of side wall.
The advantages claimed for this arrangement are
Simplicity of construction reduction in height of building and elevators necessary
and consequent reduction in first cost.
Less wear and tear of gearing in consequence of it being more out of the way
of dust.

COMPLETE SPECIFICATION.
Improvement in Arrangement of Mills for Grinding Cement,
Phosphates, and other Substances.
We, WILLIAM FREDRICK GOREHAM of 30 Hotspur Street Tynemouth in the
County of Northumberland Cement Works Manager late of 22 Erskine Road, South
Shields in the County of Durham and MICHAEL WATSON of 12 Elswick Row in
the City and County of Newcastle upon Tyne Engineer late of 82 Rye Hill in the
same City & County do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
n and by the following statement:-
In general the arrangement for driving mill stones consists of a lay shaft running
underneath them, the motion being transmitted through bevil gearing; the floor on
which the stones are placed being necessarily raised to allow room for this gearing.
The material to be ground is raised by elevators to a bin or hopper placed directly
overhead & fed from thence to the stones.
Our arrangement consists of placing the stones at or about the ground level the
driving being from lay shaft running overhead carried by girders, the motion being
transmitted by suitable gearing.
The vertical spindle is made so as to be readily disconnected above the stone (tu
allow of the latter being lifted) the bottom running in suitable bearing, adjustable
or otherwise. carried by bed stone, or by footstep below, and where desirable by both
these methods.

page_text: The hopper is placed at one side of the stones preferably at outside of side wall.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1st. A grinding mill driven from lay shaft running overhead substantially as
hereinabove described.
