West Virginia, United States of America.]
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
This invention relates to improvements in machines for separating substances of
different specific gravities in which the material being treated is projected into an
upward flowing current of water.
The objects of the invention are to provide means for thoroughly separating
the material being treated in a simple and effective manner by first controlling the
speed of the upward flowing column or current of water; secondly, controlling
the speed of projecting of the material into the water; thirdly by adjusting the
height of the overflow outlet through which the material of lighter specific gravity
is allowed to escape with the upward flowing current of water; and fourthly,
collecting and carrying away the material of heavier specific gravity.
The so called controlling chamber has its bottom made hopper shape for directing
the material which is of too great a specific gravity to be raised by the upward
flowing column of water downwardly into the receptacle to be hereinafter more
fully described.
The means for admitting water into the controlling chamber consists of a
suitable inlet pipe which enters the controlling chamber and there extends along
both ends and the sides of the chamber. Along the under side of the water inlet
pipe within the chamber is provided suitable openings in the present instance
through nipples for directing the water downwardly. The inlet pipe is provided
with a suitable cock exterior to the chamber for regulating the amount of water
supplied to the interior of the said chamber.
Rising upwards from the control chamber is a vertical compartment for directing
the current of water from within the chamber upwardly. One side of the upright
compartment is provided with suitable outlet for the upward flowing current of
water and the material of lighter specific gravity which is carried upward thereby,
which outlet, in the present instance is adjustable vertically and is in the form of a
suitable spout. This spout is adjustable in the following manner:-
Each of the end walls of the compartment is provided with a groove extending
from its top downwardly to within a short distance from its bottom and within these
grooves are fitted to slide cross slats. It will be seen that by inserting a proper

page_text: number of cross slats beneath the spout, the said spout may be adjusted to any
desired height within the compartment.
An adjustable chute is located in position to direct the material to be separated
into the upward flowing current of water within the trunk. The lower end of the
said chute is hinged, to the trunk and it is provided with a suitable elastic water-
tight joint with the said trunk, which joint in the present instance consists of two
sheets of rubber or other elastic material, which are fastened at their ends to the
chute and to the trunk. The chute is made adjustable to any desired inclination
by means of suitable sector racks hinged at their forward ends to the trunk and
their teeth being engaged by a suitable spring actuated pawl on, the chute. The
free or upper end of said chute is provided with a suitable hopper for the recep-
tion of the material to be treated.
A gate for controlling the speed of the upward flowing column of water for
more effectually separating the material being treated, is located within the trunk
and is hinged along its upper edge to the lower edge of the chute. The gate may
be swung back and forth by any suitable means. In the present instance there is
a pivoted rocking lever having a pin and slot connection at its inner end with the
gate, and having a suitable operating handle without the compartment.
A water tight receptacle for receiving the separated material of heavier specific
gravity is located beneath the control chamber and communicates therewith
through a suitable connecting pipe which is provided with a valve. The receptacle
is provided with suitable traction wheels running upon a track for facilitating the
removal of the said receptacle.
A suitable support is provided for supporting the controlling chamber, connect-
ing pipe, trunk and chute at the proper height above the level of the ground, so
that the receptacle may be readily moved into position beneath the connecting
pipe and also moved away for conveying the separated material to any point
desired.
In operation, the several parts are adjusted for use in connection with the par-
ticular material to be treated by properly adjusting the angle of the inclination
of the chute the height of the outlet in the trunk and the admission of water
through the pipe is properly controlled by the valve. The gate is also properly
adjusted to obtain the proper speed in the upflowing column of water for effectually
separating the material as it enters the trunk from the chute. The water will
first fill the controlling chamber and receptacle. It will then flow upwardly in
the trunk and chute until the level of the water reaches the height of the outlet
in the trunk. As the material to be separated is projected through the chute into
the trunk the substance of lighter specific gravity are carried upwardly by the
current of water and out through the outlet. The heavier substances are allowed
to fall into the control chamber and from there positively directed down into the
receptacle by the downwardly projected jets in the inlet pipe. When the receptacle
has received the proper amount of separated material, the valve is closed and the
receptacle is removed and another receptacle may be placed in position, or the same
receptacle may be returned after having its contained material removed. The
rest of the machine may be still allowed to operate, if so desired and allow the
material of heavier specific gravity to accumulate in the lower part of the control
chamber until the valve is opened, or the balance of the machine may be stopped
until it is desired to start it again.
It will be seen that the separator as above described, may be used for separating
any two substances of different specific gravities, or for the purpose of separating
a heavy substance from several lighter ones, such for example as separating ore
from ore pulp.

page_text: Improvements in Machines for Separating Substances of Different
Specific Gravities.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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 machines for separating substances of
different specific gravities in which the materiál being treated is projected into an
upward flowing current of water.
The objects of the invention are to provide means for thoroughly separating
the material being treated in a simple and effective manner by first controlling the
speed of the upward flowing column or current of water; secondly, controlling
the speed of projection of the material into the water; thirdly, by adjusting the
height of the overflow outlet through which the material of lighter specific gravity
is allowed to escape with the upward flowing current of water; and fourthly,
collecting and carrying away the material of heavier specific gravity.
In the accompanying drawing
Figure 1 represents a transverse, vertical section through the machine, the
detachable receptacle for receiving the separated material being shown in end
elevation, and
Figure 2 is a longitudinal, vertical section through the machine.
The so called controlling chamber is denoted by A and its bottom is of hopper
shape, as shown at a, for directing the material which is of too great a specific
gravity to be raised by the upward flowing column of water downwardly into the
receptacle to be hereinafter more fully described.
The means for admitting water into the controlling chamber consists of a
suitable inlet pipe B which enters the controlling chamber A and there extends
along both ends and the sides of the chamber. Along the under side of the water
inlet pipe B within the chamber A, is provided suitable openings b, in, the present
instance through nipples for directing the water downwardly. The inlet pipe B
is provided with a suitable cock 61 exterior to the chamber A for regulating the
amount of water supplied to the interior of the said chamber.
Rising upwards from the control chamber A is a vertical compartment or trunk C
for directing the current of water from within the chamber A upwardly. One
side of the upright compartment C is provided with suitable outlet c for the upward
flowing current of water and the material of lighter specific gravity which is
carried upward thereby, which outlet, in the present instance is adjustable
vertically and is in the form of a suitable spout c¹. This spout is adjustable in
the following manner :-
Each of the end walls of the compartment C is provided with a groove c³ extend-
ing from its top downwardly to within a short distance from its bottom and within
these grooves, are fitted to slide cross slats c³. It will be seen that by inserting a
proper number of cross slats 3 beneath the spout c', the said spout may be adjusted
to any desired height within the compartment C.
An adjustable chute D is located in position to direct the material to be separated
into the upward flowing current of water within the trunk C. The lower end of
the said chute is hinged, as shown at d, to the trunk C and it is provided with a
suitable elastic water-tight joint with the said trunk C, which joint in the present
instance consists of two sheets of rubber or other elastic material d¹, d² which are
fastened at their ends to the chute D and to the trunk C. The chute D is made

page_text: adjustable to any desired inclination by means of suitable sector racks E, hinged
at their forward ends at e to the trunk C and their teeth e¹ being engaged by a
suitable spring actuated pawl e³ on the chute D. The free or upper end of said
chute is provided with a suitable hopper D¹ for the reception of the material to
be treated..
A gate F for controlling the speed of the upward flowing column of water for
more effectually separating the material being treated, is located within. the trunk C
and is hinged along its upper edge to the lower edge of the chute D, as shown at f.
The gate may be swung back and forth by any suitable means.
In the present
instance there is shown a rocking lever G pivoted at g and having a pin and slot
connection at its inner end with the gate F, as shown at g', and having a suitable
operating handle g² outside the compartment C.
A water tight receptacle H for receiving the separated material of heavier
specific gravity is located beneath the control chamber A and communicates there-
with through a suitable connecting pipe I which is provided with a valve i. The
receptacle H is shown in the present instance as being provided with suitable
traction wheels h running upon a track h¹ for facilitating the removal of the said
receptacle.
A suitable support J is provided for supporting the controlling chamber, con-
necting pipe, trunk and chute at the proper height above the level of the ground,
so that the receptacle H may be readily moved into position beneath the con-
necting pipe I and also moved away for conveying the separated material to any
point desired.
In operation, the several parts are adjusted for use in connection with the par-
ticular material to be treated by properly adjusting the angle of the inclination
of the chute D, the height of the outlet c in the trunk C and the admission of
water through the pipe B is properly controlled by the valve b. The gate F is
also properly adjusted to obtain the proper speed in the upflowing column of water
for effectually separating the material as it enters the trunk C from the chute D.
The water will first fill the controlling chamber A and receptacle H. It will
then flow upwardly in the trunk C and chute D until the level of the water reaches
the height of the outlet c in the trunk C. As the material to be separated is pro-
jected through the chute D into the trunk C, the substance of lighter specific
gravity are carried upwardly by the current of water and out through the outlet c.
The heavier substances are allowed to fall into the control chamber A and from
there positively directed down into the receptacle H by the downwardly projected
jets in the inlet pipe B. When the receptacle H has received the proper amount
of separated material, the valve i is closed and the receptacle H is removed and
another receptacle may be placed in position, or the same receptacle H may be
returned after having its contained material removed. The rest of the machine
may be still allowed to operate, if so desired and allow the material of heavier
specific gravity to accumulate in the lower part of the control chamber A until
the valve i is opened, or the balance of the machine may be stopped until it is
desired to start it again.
It will be seen that the separator as above described, may be used for separating
any two substances of different specific gravities, or for the purpose of separating
a heavy substance from several lighter ones, such for example as separating ore
from ore pulp.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondents, I declare that what I claim is:-
1. A machine for separating substances of different specific gravities, comprising
a control chamber, water feeding means therefor, a receptacle communicating
with the control chamber for receiving the material of heavier specific gravity, a
trunk or compartment uprising from the control chamber and having a suitable
outlet for the upward flowing current of water and substances of lighter specific

page_text: gravity, a chute for feeding the material to be separated, hinged to the said trunk,
and means for adjusting the inclination of the chute, substantially as set forth.
2. In a separator, a control chamber, a trunk uprising therefrom and provided
with a suitable outlet for the upward flowing current of water and substances of
lighter specific gravity, a chute for directing the material to be operated upon into
the trunk, means for feeding water under head or pressure into the control chamber,
a gate hinged at the discharge end of the chute within the trunk and means for
adjusting the free lower end of the gate in different positions across the interior
of the trunk to adjust the action of the separator to materials of varying specific
gravities with precision, substantially as set forth.
3. In a separator, a control chamber provided with converging inclined bottom
walls, a trunk uprising from the chamber and provided with a suitable outlet for
the upward flowing current of water and substances of lighter specific gravity,
a chute for directing the material to be operated upon into the trunk, means for
controlling the passage of the material into and the passage of the water from the
control chamber and a water feed pipe within the control chamber provided with
downwardly discharge openings at intervals above the inclined bottom walls for
causing the currents of water to impinge the said inclined walls and material
thereon to prevent clogging, substantially as set forth.
