and other Substances.
I, JULIUS BUSS, of 32, Victoria Street, Westminster, in the County of Middle-
sex, Engineer, do hereby declare the nature of this invention to be as follows:-
In the accompanying drawings,
Figure 1 is a front view, partially shown in section.
Figure 2 is a cross section, and
Figure 3, a plan view of the said apparatus.
This machine is based on the following new principle:-
--
The minerals or other substances in form of pulp are received on a rectangular
table A made of wood or other suitable material shown in Figures 1, 2 and 3.
The table can be inclined transversely and longitudinally by means of the
adjusting screws B and C respectively. The pulp is fed on to the said table
by means of a stationary feed-trough D fixed at the upper end of the table and
provided with hollow brushes at the bottom which spread the pulp evenly on
to the table.
The table rests on a number of springs E attached to the table and supported
on cross pieces F. The springs which may be of wood or other suitable material
are fixed at an angle to the longitudinal axis of the table and held in position by
brackets & fixed on the cross pieces.
The cross pieces rest on frame H and are provided at the upper end with the
adjusting screws B by means of which the inclination of the table can be
increased or decreased transversely as required.
An eccentric K connected with the table by means of a rod L imparts to the
table a peculiar reciprocating upward and downward movement in an oblique
direction causing the material to be separated into layers according to the
specific gravity of its components and to be carried longitudinally forward.
towards the end M of the table and at the same time downwards transversely,
the table being transversely inclined.
The eccentric K is adjustable so as to allow the stroke to be increased or
decreased as required.
The rod L is also adjustable and may be lengthened or shortened as required,
thus altering the angle of the springs E.
On its way the material is subjected to the action of water pouring down-
wards transversely, the water being spread evenly over the surface of the table
by means of a water-pipe N perforated with small holes and fixed either longi-
tudinally on the upper edge of the table or diagonally across the table in the
direction shown in Figure 3.
Through the combined action of the movement of the table and the water

page_text: flowing downwards transversely the various materials are separated one from
the other according to their specific gravity
The lighter parts are washed downwards transversely and discharged over
the lower side of the table into the shoot P. The heavier parts, travelling
faster and offering more resistance to the water, are carried towards the end of
the table and discharged over the end of the table into shoot Q from which
they are taken to proper receptacles.
Modifications may be made in the form of the surface of the table; for
example, fixed or removable strips, longitudinally and transversely adjustable
and also if desired adjustable as to height may be provided upon it.
Improvements in Apparatus for Concentrating and Separating Ores
and other Substances.
I, JULIUS Buss, of 32, Victoria Street, Westminster, in the County of Middle-
sex, 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 ore concentrators or separators of that kind in
which the action of water flowing over a reciprocating table is employed.
In such concentrators as at present made the table is caused to reciprocate
in a direct horizontal plane only.
According to my present invention I employ a table inclined transversely
and in some cases longitudinally also, and the table is so mounted as to receive
instead of a horizontal reciprocating motion a combined reciprocating and rising
and falling motion in an oblique direction, this motion being obtained by
mounting the said table upon inclined springs or resilient supports or suspend-
ing it on flexible supports whilst the reciprocating motion is imparted to the
table at an angle therewith by means of a cam or eccentric.
In the drawings which accompanied the Provisional Specification, Fig. 1 is
a front view, partially shown in section, Fig. 2 is a cross-section, and Fig. 3
a plan view of the said apparatus.
In the drawings A is the rectangular table of wood or other suitable material
onto which the mineral ore or other substances to be treated are fed in the form
of pulp by a feed trough D suitably supported and situated at the upper end or
corner of the table A and provided with holes & through which the pulp is fed.
The table A is supported on a number of springs or resilient supports E
attached thereto and made of wood or other suitable material. These springs E
are as shown in Fig. 1 disposed at an angle to the longitudinal axis of the table
and held in position by brackets G fixed on cross pieces F. The cross pieces F
rest upon a frame H and are provided at their upper ends with adjusting
screws B by means of which the transverse inclination of the table can be
increased or decreased as required. Similar adjusting screws C are provided
at one end of frame H for adjusting the longitudinal inclination of the table.
The table receives its peculiar reciprocating upward and downward move-
ment in an oblique direction from an eccentric K which acts with the springs E
and is connected to the table by a rod L. This eccentric is suitably mounted

page_text: on a shaft & arranged in an extension of the frame H and is driven by speed
pulleys and suitable fly wheels are provided.
The eccentric K is made so as to be adjustable for increasing or decreasing
the stroke of the rod L, which latter is also arranged to be lengthened or
shortened as required. for instance by nuts or whereby the angle of the
springs E may be adjusted.
P
N is a water supply pipe perforated with small holes and arranged either
longitudinally on the upper edge of the table or diagonally across same.
and Q are the usual discharging shoots disposed at the lower side and end of the
table.
It will be obvious that without departing from the nature of my invention
the table A may, instead of resting in a frame on springs F, be suspended by
springs or flexible parts from a frame above the table, the arrangement being
such as to allow of the table being inclined transversely and longitudinally
and reciprocated in the peculiar manner described.
In operation the minerals or other substances in the form of pulp are fed
onto the upper end or corner of the table by the feed trough D as described
and the peculiar reciprocating upward and downward movement in an oblique
direction imparted to the table by the eccentric K and springs E causes the
material to be separated into layers according to the specific gravity of its com-
ponents and to be carried longitudinally forward toward the end M of the table
and at the same time downward transversely, the table being transversely
inclined. As is usual with this class of apparatus the material in its passage
across the table is subjected to the action of water pouring downward thereover
transversely from the perforated water pipe N.
Through this continued action of the peculiar movement of the table and
water flowing transversely the various materials are separated one from another
according to their specific gravity and in a more effectual manner than is the
case with existing machines of this class.
The lighter parts are, washed downward transversely and discharge over the
lower side of the table into the shoot 1. The heavier parts travelling faster
and offering more resistance to the water are carried towards the end of the
table and discharged over its end M into shoot from which they are removed
to proper receptacles.
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. In an ore concentrator or separator of the kind described the use of a con-
centrating table inclined as described and having imparted thereto a combined
reciprocating and upward and downward motion in an oblique direction, sub-
stantially as and for the purpose set forth.
2. The improvements in ore concentrators or separators of the kind described
comprising a concentrating table adjustably inclined transversely or trans-
