I CHARLES SHEPPARD, of The New Foundry, Bridgend, in the county of
Glamorgan, 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 :—
This invention relates to improvements in machinery or apparatus for facilitating
the washing or cleansing of ores and minerals from impurities such as earthy and
clayey matters and for cleansing sand, clay, earths and other substances; also for
dissolving and running off clay and other substances.
In order to enable my invention to be fully understood I will describe the same
by reference to the accompanying drawings in which figures 1 and 2 sheet 1 are
elevations of a machine constructed according to my invention and suitable for
washing or cleansing hard substances such as ores which will not dissolve; figure 3
sheet 2, is an elevation of part of the machine shewing the same adapted for
washing or cleansing substances which can be dissolved such as clays, earth or sand.
Similar letters in all the figures represent similar or corresponding parts.
I will first describe my invention by reference to figures 1 and 2.
The Ores or other hard substances to be operated on are brought to the machine
by trucks A, or by other suitable means and placed in a washing cylinder B,
through an opening A, fitted with a cover which can be easily and quickly opened
and closed; as soon as the desired quantity has been placed in the cylinder B, the
said cover is securely closed; water is then allowed to flow in through a pipe c³,
and hollow trunnion C, to the washing cylinder B, which is made to rotate with
the said hollow trunnion C, and the hollow trunnion C², by suitable gearing such
as that shewn at D, E in the drawing; the washing cylinder B, has its trunnion C,
and C¹, placed eccentrically to its axis and diametrically opposite to each other so
that the cylinder shall revolve in an oblique position as shewn in the drawing.
By this means when the cylinder is rotated the ores or other substances within
the same are violently agitated and thrown against each other and against the
inside of the cylinder; the water as hereinbefore described flows into the cylinder

page_text: through the pipe o³, and trunnion C, and dissolving the earth or clay or other im-
purities from the ores or other substances flows out at the other end of the cylinder
at c, carrying with it the clay and earthy matter or other impurities dissolved;
this operation is continued until the said ores or other substances are thoroughly
cleansed; the flow of water is then stopped, the cylinder is brought to rest with its
cover or opening A downwards and is then opened when the clean ore or other
substance can be discharged into a truck F, or other receptacle placed to receive it.
The water as it flows out of the cylinder B, at C, falls into a trough E, and if,
of no value is allowed to flow away; if however the clay or earth dissolved thereby
is of value for the manufacture of bricks, tiles, or earthenware it is allowed to flow
into suitable tanks from which after the clay or other substance has settled at the
bottom the water is run off, and the clay or other substance is removed to be made
use of for any required purpose for which it is suited.
When the substances such as clays, earth or sand to be washed or cleansed from
impurities will dissolve in water I feed them into the cylinder through a large
trunnion as shewn at C, in figure 3, of the drawing through which trunnion the
water also runs in and as the substances become dissolved they flow out through
the trunnion C, and through suitable troughs or pipes to settling tanks; as soon as
the clay or earth becomes settled at the bottom of the tanks the water is run off
and may be used again if desired; the substances remaining are removed for manu-
facturing purposes and the impurities which were mixed with the clays, earth or
the like, and which will not dissolve are periodically removed through the opening A
of the cylinder which is brought to rest in the manner hereinbefore described for
that purpose.
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
1. The combination of parts forming the improved machine or apparatus for
washing or cleansing ores or other hard substances substantially as herein before
described and represented in figures 1 and 2 sheet 1 of the accompanying drawing.
2.. The combination of parts forming the improved machine or apparatus for
washing soluble clays, earths or other substances substantially as hereinbefore
described and represented in figure 3, sheet 2 of the accompanying drawing.
