PROVISIONAL SPECIFICATION.
Improvements in Revolving Tables for Sorting Minerals.
I LLOYD WILSON of Scaur Close Broughton Cross via Carlisle, in the County of
Cumberland, Civil Engineer, do hereby declare the nature of my invention for
"IMPROVEMENTS IN REVOLVING TABLES FOR SORTING MINERALS" to be as
follows:-
The table instead of being a plain surface, is constructed, so that the middle
portion round the shaft is open and separated from the rest of the table by a ledge
fixed to, and standing at right angles to the table all round the edge of the opening
see (B) on plan.
This keeps the mineral to be sorted, or cleaned, from getting nearer the centre than
this fixed ledge and upon the revolving portion of the table (A) which is arranged
to carry such mineral to a shoot leading where required.
The frame of the table is made with as few arms as possible radiating from the
centre marked C & C on plan. These in the case of driving from beneath would be
the spokes of the crownwheel-C is an extension of arms or spokes C which can be
carried out to required diameter of table.
Underneath them, at a convenient distance is placed a stationary table !) on plan.
This is so arranged, that the arms-alone, or with scrapers attached to them, if
desired, will pass over it, and as they revolve carry round with them any substance
placed in the centre opening of the revolving table.
At any point in this stationary table most convenient, an opening is made-so that
as the substance is carried round by the arms it will all drop through it into a spout
and can be conveyed to any desired place below, (E).
The centre shaft is protected by a pipe or sheath F fixed on the revolving table
frame, and carried to any height desired.

Improvements in Revolving Tables for Sorting Minerals.
I, LLOYD WILSON of Scaur Close, Broughton Cross in the County of Cumberland,
Civil 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:-
The table is constructed as shown in the drawings left with the provisional
specification, and in the following, the letters used on that drawing are referred to.
The frame is made with as few arms as possible, which in case of driving from
underneath, are the spokes of the crown or driving wheel C and with extension
arms Crivetted to them, and stretching to any given length. The plate A forms the
lable upon which the material to be sorted is placed, and is fixed to these arms but does
not extend nearer the centre than the shield B, which prevents the said material
from getting too near the middle portion of the table. Those who sort the material
on the table A are protected from it by a fixed plate or shield not shown on the
drawing.
Under the arms C is placed a fixed table D over which they, or scrapers attached
to them pass, and in which at any desired point is constructed an opening into a
shoot E.
The material sorted out from table A is thrown inside shield B and goes through
between the arms Con to the table D and is carried round by the arm to the shoot E.
F is a shield to protect the main shaft if required.
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 :-
The utilizing of the centre portion of the table for the reception of the material
sorted out from table A and the carrying of such material by the arms C revolving
over the fixed table D to any desired place by shoot E.
Dated this 2nd day of October 1888.
