1 NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex Engineer do hereby declare the nature of this invention to
be as follows:-
-
minerals and
My invention relates to machines of that class wherein stones, ores,
other materials are broken and crushed between a stationary and a moveable jaw.
The moveable jaw of my improved crushing machine has a direct acting
reciprocal motion imparted to it by a cam which revolves in a sleeve or case
formed on or connected to a tail-piece on moveable jaw.
To support the weight of the moveable jaw and to direct the thrust imparted to
it by the action of the cam I provide it with projections working on fixed slides or
with moveable links hinged to the frame-work or otherwise suitably connected.
The cam sleeve or case can be provided with an eccentric liner to take the wear
of the cam as well as to enable variation to be made in the gauge to which any
material has to be crushed.
The front block carrying the fixed jaw may be made independent of the
standards or supports carrying the cam shaft bearings to which it may be connected
by rods in such a manner that the distance between the fixed jaw and moveable
jaw can be regulated to suit the gauge to which the material has to be crushed
suitable provision being made to enable the front block to slide on its supports.

Minerals, and other Materials.
I NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex 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 :-
My invention relates to machines of that class wherein stones ores minerals and
other materials are broken and crushed between a stationary and a moveable jaw.
The invention is illustrated in the accompanying sheet of drawings wherein
Fig. 1 represents a longitudinal vertical section and Fig. 2 an horizontal section
through my improved breaker or crusher.
AA represent two side standards or supports for the driving shaft B to which
shaft motion is imparted from any convenient source by a driving belt running
over the pulley C or by other suitable means DD represent two fly wheels
revolving with the driving shaft B.
The moveable jaw E of my improved crushing machine has a direct acting
reciprocal motion imparted to it by a cam b on the driving shaft B which revolves
in a sleeve or case e formed on or connected to a tail piece on moveable jaw E.

page_text: To centrally support the weight of the moveable jaw E and to direct the thrust
imparted to it by the action of the cam b thereby causing a greater regularity of
output than can be obtained in machines having swinging jaws of the "Blake" type
I provide it with projections F F at or near the position, shown these projections
working on fixed slides or with moveable links G G hinged as at g to the
framework H or otherwise suitably connected.
The small radial movement given to the crushing face of the moveable jaw E
will tend to release any material with which the toothed surface of the jaws may
become clogged.
The cam sleeve or case e can be provided with an eccentric liner as shown at i
Fig. 3 to take the wear of the cam b as well as to enable variation to be made in
the gauge to which any material under operation has to be crushed.
The front block J carrying the fixed jaw K may be made independent of the
standards or supports A A carrying the cam shaft bearings to which it may be
connected by tension rods L L in such a manner that the distance between the
fixed jaw Kand moveable jaw E can be regulated to suit the gauge to which the
material has to be crushed suitable provision being made to enable the front
block J to slide on its supports.
Having now described the nature of my invention and shown how the same may
be carried into practise I claim
1st. The improved direct acting vibrating jaw crushing machine as herein
described and illustrated at Figs. 1 and 2.
2nd. In vibrating jaw crushing machines the combination of a direct acting
moveable jaw centrally supported with the adjustable tension rods substantially as
herein described and illustrated and for the purposes set forth.
3rd. In vibrating jaw crushing machines the combination of a direct acting
moveable jaw with the moveable links pivotted to the framework of the machine
and to the projections centrally supporting the moveable jaw as herein described
and illustrated.
4th. In vibrating jaw crushing machines the use of an eccentric liner as illus
trated in Fig. 3 in combination with a direct acting moveable jaw centrally
supported as and for the purposes herein described.

PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Concentrating Ores, Minerals, and
other Materials.
I NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex Engineer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to apparatus for the concentration of eres minerals and
other materials.
The materials to be concentrated having been suitably prepared by grinding,
crushing, pulverizing, screening or other means is delivered into a chamber or
hopper at the top of my concentrator and falls into a restricted or concentration
passage where it meets a current of air or water by which the lighter particles
will be separated and carried away with the current of air or water while all those
particles whose weight enables them to overcome the resistance of the current of
air or water will fall into a receiver.
The restricted or concentration passage is formed on a curve with the object of
causing the force of the current of air or water to have greater effect on the
material at the lower portion of the restricted or concentration passage than at
the top where the material enters.
Suitable arrangements may be provided for varying the dimensions of the space
in the restricted curved passage also for varying the force of the current of air
or water to suit the nature of the material under treatment.
The receiver may have an opening formed at or near its base controlled by a
balanced valve through which the concentrates will be automatically delivered
when the accumulated weight of the concentrates in the receiver overcomes the
weight or force with which the valve is balanced or the concentrates may be
removed from the receiver by an elevator or other suitable means.
When my improved apparatus is being used for the concentration of gold or
silver ores, I may provide an auxiliary revolving chamber provided with discs,
partitions, or baffle plates to which elevating scoops or stirring appliances may be
connected and into and through which the current of air or water carrying the
lighter particles will pass and in which the metallic particles will be deposited by
reason of their higher specific gravity.
By the employment of quicksilver either loose or amalgamated with copper
plates inside the revolving chamber the same may be used as an amalgamator for
the purpose of obtaining in the form of an amalgam the particles of gold or silver
deposited therein.

other Materials.
I NATHAN GOLD KIMBERLEY of Springfield Road New Southgate in the
County of Middlesex 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:—
My invention relates to apparatus for the concentration of ores minerals
and other materials and is illustrated in the accompanying sheet of drawings
wherein
Fig. 1 represents in section my improved vertical concentrator.
Fig. 2 represents in section another form of my improved vertical concentrator
wherein means are provided for varying the dimensions of the space in the
restricted curved passage and an outlet controlled by a balanced valve is provided
at the base of the receiver for the delivery of the concentrates.
Fig. 3 represents a longitudinal section and Fig. 4 a section through line of
Fig. 3 of my improved auxiliary cylinder.
The material to be concentrated having been suitably prepared by crushing
grinding pulverizing screening or other means is delivered into a chamber or
hopper A at the top of my concentrator and falls through the chamber B the
dimensions of its outlet can be regulated by the slide C controlled by the rod c
passing through the the fixed arm D and locked in position by the nuts c¹ and
into a restricted or concentration passage E where it meets a current of air or
water entering at G by which the lighter particles will be separated and carried
away with the current of air or water through the upper chamber or enlarged
passage H and the outlet J while all those particles whose weight enables
them to overcome the resistance of the current of air or water will fall into a
receiver F.
The restricted or concentration passage E is formed on a curve with the object
of causing the force of the current of air or water to have greater effect on the
material at the lower portion of the restricted or concentration passage than at
the top where the material enters.
Suitable arrangements may be provided for varying the dimensions of the space
in the restricted curved passage one mode for which is shown in Fig. 2 wherein
e represents a curved plate hinged at e forming one side of the restricted curved
passage E controlled in position by the eyed bolt whose screwed shank passes
through the nut e" working in the side of the concentrator frame.
Arrangements may also be provided for varying the force of the current of air
or water to suit the nature of the material under treatment.
The receiver F may have an opening f formed at or near its base controlled by
a balanced valve through which the concentrates will be automatically delivered
when the accumulated weight of the concentrates in the receiver overcomes the
weight or force with which the valve is balanced or the concentrates may be
removed from the receiver by an elevator or other suitable means.
When my improved apparatus is being used for the concentration of ores I may
provide an auxiliary cylinder Figs. 3 and 4 provided with discs partitions or baffle
plates K smaller in diameter than the inner side of the cylinder to which they
will be connected in such a manner as to leave an open space between the edges
of the discs partitions or baffle plates K and the cylinder through which open
space the heavier particles of metal or ore will pass as the cylinder revolves on
their way to the outlet at L.
Elevating scoops M for the purpose of lifting any material that may accumulate

page_text: n the cylinder or stirring appliances may be connected
baffle plates K.
Into and through this auxiliary revolving cylinder the current of air or water
carrying the lighter particles from my improved vertical concentrator will pass
and in which the metallic particles will be deposited by reason of their higher
specific gravity.
By the employment of quicksilver either loose or amalgamated with copper
plates inside the revolving cylinder the same may be used as an amalgamator for
the purpose of obtaining in the form of an amalgam the particles of gold or silver
deposited therein.
