Empire of Germany.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323 High Holborn, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object an apparatus for separating, washing or dressing
ores in which a jigger formed to receive a bedding or layer of ore exposed to a current
or volume of water is adapted to be vertically reciprocated or agitated, whereby the ore,
at every plunge of the jigging sieve, will be separated, the lieavy particles of metal
concentrating in a suitable vessel, while the débris is carried away through a sluice or
waste pipe.
«
an
The apparatus which might be called, in view of its use and construction,
hydraulic circular percussion jigger" comprises a vessel preferably formed of iron
plates, circular in shape at its upper part, and its bottom part sloping from the
circumference or outer wall towards the centre; then rising again also towards the
centre, thus forming an annular channel or gutter in the form of an inverted cone.
By this arrangement is formed in the lower part of the vessel a V shaped channel
wherein are arranged at suitable distances the discharge pipes.
The vessel is supported by a suitable number of arched standards, connected above
the vessel and in the centre by means of a ring or annular plate supporting the
driving apparatus, which comprises two pulleys, one fixed and one loose on the shaft,
eccentric, eccentric rod and the fly wheel. The eccentric rod runs through a collect-
ing funnel or hopper which receives the orey water, and terminates in the ring or
annular plate which is bolted to the columnar waste pipe. It furthermore carries the
levers pivoted to the supporting arms of the ring. To the outside ends of the levers
the annular percussion sieve is suspended, which guided in a closing ring is moved up
and down by the levers pivoted to the arms of the vertically reciprocating ring
aforesaid.
For the purpose of facilitating the movement of the sieve, it is balanced by a
counter-weight suspended to the inside arms of the levers.
The mode of action is as follows:-
The orey water flows through gutters into the funnel provided around its bottom
end with pipes which convey the orey water to the periphery of the percussion sieve
in the annular channel from whence it is fed onto the sieve in jets by means of the
pipes arranged for this purpose at equal distances around the channel. On this
percussion sieve is placed in the usual manner a bedding or layer of clean ore and as
the vessel is always full of water, this bedding will be agitated at every plunge of the
sieve and thus allows the heavy grains of ore to sink into and concentrate into
the bottom of the V-shaped vessel. From here the grains are discharged through
the pipes into the collecting gutter, whilst the slime on the sieve pushed by the
continually admitted jets of orey water towards the centre of the vessel and is
discharged in the columnar waste pipe and is thus removed.
The water lost partly at the upper part of the jigger (through the bedding on the
sieve which closes tightly against the side walls of the vessel) and partly at the lower
end (through the discharge pipes) is continually replaced by the feed water pipes
suitably arranged in the vessel.
The apparatus is eminently fitted for work in mountains difficult of access and far
from industrial centres, as it constitutes a complete whole and is easily transported and

page_text: requires for its operation very little power and consequently can be mounted
directly in the open air.
Where the questions of transportation and of power are not of the first importance,
and when the apparatus is to be used in localities where power may be readily
obtained, an alternative form of construction may be employed in which the eccentric
is mounted on a power transmission shaft, whereby a series of apparatus may be
operated from the same shaft. The eccentric rod goes through the collecting funnel
for the orey water and then is carried through a circular distributing disc. It also
carries levers whereto the percussion sieve is suspended.
The collecting funnel is carried by special supporting arms and around its bottom,
discharge openings are arranged, admitting the orey water onto the distributing disc
whereon it spreads in all directions and is thus conveyed in a uniform manner into the
dividing gutter from which it is fed on the sieve.

Improvements in Apparatus for Separating, Washing, or
Dressing Ores.
A communication from abroad by OSCAR BILHARZ, of Freiberg, Saxony, in the
Empire of Germany.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.L.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both in
the County of Lancaster, and 323, High Holborn, in the County of Middlesex, 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 invention has for its object an apparatus for separating, washing or dressing
ores in which a jigger formed to receive a bedding or layer of ore exposed to a
current or volume of water is adapted to be vertically reciprocated or agitated,
whereby the ore, at overy 'plunge of the jigging sieve, will be separated, the heavy
particles of metal concentrating in a suitable vessel, while the débris is carried
away through a sluice or waste pipe.
The invention is best described by aid of the accompanying drawings, in which,
Figure 1 is mainly a vertical section of the apparatus, but certain parts cut by the
sectional plane are shewn for the sake of clearness in elevation.
Figure 2 a plan, and
Figures 3 and 4 a modified construction of the apparatus, Figure 3 being a vertical
section, and Figure 4 a sectional plan, half of which is a horizontal section on the
line a band the other half a horizontal section on the line e d.
an
The apparatus which might be called, in view of its use and constructions,
hydraulic circular percussion jigger," comprises a vessel T preferably formed of iron
plates, circular in shape at its upper part, and its bottom part sloping from the circum-
ference or outer wall towards the centre; then rising again also towards the centre,
thus forming an annular channel or gutter in the form of an inverted cone. By this
arrangement is formed in the lower part of the vessel T a V-shaped channel wherein
are arranged at suitable distances the discharge pipes a¹.
h
The vessel T is supported by a suitable number of arched standards U connected
above the vessel and in the centre by means of a ring or annular plate supporting
the driving apparatus, which comprises two pulleys and one fixed and one loose on
the shaft R, the eccentric with the eccentric rod g and the fly wheel m². The
eccentric rod runs through a collecting funnel or hopper V, which receives the orey
water, and terminates in the ring or annular plate Y which is holted to the columnar
waste pipe X. It furthermore carries the levers n and p pivoted to the supporting
arms and of the ring Y. To the outside ends of the levers n and p the annular

page_text: up and
percussion sieve S is suspended, which guided in a closing ring t is moved
down by the levers n and p pivoted to the arms of the vertically reciprocating ring Y
aforesaid.
For the purpose of facilitating the movement of the sieve, it is balanced by a
counterweight & suspended to the inside arms of the levers n and p.
The mode of action is as follows
The orey water flows through gutters m into the funnel V provided around its
bottom end with pipes e, which convey the orey water to the periphery of the
percussion sieve S in the annular channel, from whence it is fed onto the sieve by
means of perforations arranged for this purpose at equal distances around the
channel.
On this percussion sieve is placed in the usual manner a bedding or layer
of clean ore and as the vessel T is always full of water, this bedding will be agitated
at every plunge of the sieve and thus allows the heavy grains of ore to sink into and
concentrate in the bottom of the V-shaped vessel T. From here the grains are dis-
charged through the pipes a' into the collecting gutter y, whilst the slime on the sieve S
is pushed by the continually admitted jets of orey water towards the centre of the
vessel T, and is discharged in the columnar waste pipe X, and is thus removed.
The water lost partly at the upper part of the jigger (through the hedding on the
sieve which closes tightly against the side wails of the vessel) and partly at the lower
end (through the discharge pipes a¹) is continually replaced by the feed water pipes v
suitably arranged in the vessel.
The apparatus is eminently fitted for work in mountains difficult of access, and far
from industrial centres, as it constitutes a complete whole and is easily transported
and requires for its operation very little power and consequently can be mounted
directly in the open air.
Where the questions of transportation and of power are not of the first importance,
and when the apparatus is to be used in localities where power may be readily
obtained, an alternative form of construction may be employed in the manner shewn
by Figures 3 and 4 of the accompanying drawings. In these figures, the eccentric /
is mounted on a power transmission shaft, whereby a series of apparatus may be
operated from the same shaft. The eccentric rod g goes through the collecting
funnel V for the orey water, and then is carried through a circular distributing disc Z.
It also carries levers and p, whereto the percussion sieve S is suspended.
The collecting funnel V is carried by special supporting arms and around its
bottom, discharge openings are arranged, admitting the orey water onto the distribu-
ting dise Z, whereon it spreads in all directions and is thus conveyed in a uniform
manner into the dividing gutter from which it is fed on the sieve S.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign correspondent, I declare that what I claim is :-
1. An apparatus for separating, washing or dressing ores, consisting essentially of
an annular vessel T with an annular percussion sieve s suspended to an eccentric g by
means of levers n p, substantially as herein described.
2. In an apparatus of the kind described the arrangement of a collecting funnel V
for the reception of the orey water above the centre of the percussion sieve s from
which the orey water is fed in a uniform way onto the sieve, which may be done either
by means of pipes v or by a distributing disc Z, substantially as set forth.
3. In an apparatus of the kind described, the arrangement of a counterweight u to
the inner arms of the levers, n p, for keeping in balance the percussion sieve 8,
substantially as set forth.
