1, CHARLES SHEPPARD, of The New Foundry, Bridgend, in the county of
Glamorgan, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to machines for washing, sorting and purifying sand, earth,
ashes, crushed minerals and the like and to apparatus for feeding the said materials to
such machines.
In carrying out my invention, I provide a box or chamber into which the material
to be operated on is feil. The material then passes through a pipe or trunk to a
washing cylinder, suspended by rods to a beam and kept in equilibrium by balance
weights, so adjusted that the washing cylinder when filled with water and partially
filled with sand undergoing the washing process, is balanced when the proper quantity
of sand or other material to be operated upon has been placed in the said cylinder ;
but any sand or other material afterwards added to the quantity will cause the
cylinder to descend and in so doing open a valve and allow a corresponding quantity
of the sand to run out until the equilibrium is restored.
The discharge valve is operated by a beam or lever, the end of which is pivoted to
the frame of the machine, the fulcrum being attached to a neck formed or fitted on
the washing cylinder.
The washing and purifying of the sand or other material is effected by a numbor of
jets of water issuing at a suitable pressure from the lower part of a centrally placed
pipe, the impurities are thus caused to rise from the sand and flow off with the water
into an annular chamber and thence away through a suitable pipe.
The sand or other material to be washed can be raised to the feed box, by means of
an injector, having a stream of water running through the centre, nozzle, the outer or
suction nozzle being in communication with a vessel or box filled with water and
sand, the issuing of water through the centre nozzle causing the sand and water to be
raised from the vessel containing it and to be discharged by a pipe leading from the
injector to the said box. The sand can however, if preferred, be raised by an
elevator consisting of buckets and chain similar to those in use in dredgers, or by other
means.

5 Improvements in and connected with Machines for Washing,
Sorting, and Purifying Sand, Earth, Ashes, Crushed Minerals,
and the like.
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
O manner the same, is to be performed to be particularly described and ascertained in
and by the following statement :-
My invention relates to machines for washing, sorting and purifying sand, earth,

page_text: employment in connection therewith of an injector for raising the materials by means
of a water jet.
In the accompanying drawing
Figure 1 is an elevation, and
Figure 2 is a vertical section of my improved machine.
Similar letters in both.the figures indicate similar parts.
a is a box or chamber into which the material to be operated on is fed. The
material then passes through a pipe or trunk & to a washing cylinder e suspended by
rods, d to a beam e fulcrummed at fand having weights y suspended therefrom, the
said weights balancing the washing cylinder c when the latter is filled with water and
a given quantity of sand or other material to be operated upon is contained therein;
any sand or other material afterwards added to the said quantity causing the cylinder c
to descend and in so doing to open a valve and allow a corresponding quantity of
the material to run into a wagon or other suitable receptacle (not shewn in the
drawing) until the equilibrium is restored.
•
The discharge valve is carried at one end of a beam or lever the other end of
which is pivotted at j to the frame or stand of the machine the lever being jointed to
a collar upon a neck m formed or fitted on the washing cylinder c. The washing and
purifying of the sand or other material is effected by a number of jets of water issuing
at a suitable pressure from the perforated lower part of a centrally placed pipe n; the
impurities are thus caused to rise from the material and flow off with the water into
an annular chamber o and thence away through a pipe p.
The sand or other material to be washed can be raised to the feed box a by means
of an injector having a stream of water running through the centre nozzle, the outer
or suction nozzle being in communication with a vessel or box filled with water and
sand or other material the issuing of water through the centre nozzle causing the
material and water to be raised from the vessel containing it and to be discharged by
a pipe leading from the injector into the box a. The material can however if
preferred bo raised by an elevator consisting of buckets carried upon a chain similar
to those in use in dredgers, or by other means.
My improved machine it will be observed is continuous and automatic in its action
sinco the material to be operated upon, as it is fed to the box a by the injector or
elevator, will pass down the pipe into the cylinder c in which it will be washed by
the water issuing under pressure from the pipe n. When however the material in the
cylinder e exceeds a given weight the cylinder will overbalance, open the valve and
discharge the bottom or most thoroughly washed portion of the material and, being
relieved of its weight, will rise, close the valve and remain in equilibrium until more
material falls into it from the box a, when it again falls and discharges a portion of
the material and so on. The impurities meanwhile rise with the water as hereinbefore
described and flow over into the chamber, o and off through the pipe p.
Instead of the valve and lever i for allowing the discharge of the clean material
this can be effected by lengthening the water pipen and closing the bottom thereof
so as to close the aperture in the bottom of the cylinder c when the latter is in equi-
librium when it descends, however, the aperture will become opened and allow the
material to escape.
;
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
(1.) The arrangement and combination of parts forming the improved machine for
washing, sorting and purifying sand, earth, ashes, crushed minerals and the like, sub-
stantially as hereinbefore described with reference to the accompanying drawing.

page_text: (2.) The uso in combination with a machine for washing, sorting and purifying
sand, earth, ashes, crushed minerals and the like of a water injector for raising the
materials into the machine substantially as hereinbefore described.
