IMPROVEMENTS IN MACHINERY OR APPARATUS FOR KIBBLING AND PULVERIZING MINERAL AND OTHER SUBSTANCES OR MATERIALS
Year: 1884

page_text: I RICHARD EDMUND SHILL of 79, Harborne Road Edgbaston Birmingham in the
County of Warwick, Engineer do hereby declare the nature of my Invention for
IMPROVEMENTS IN MACHINERY OR APPARATUS FOR KIBBLING AND PULVERIZING
MINERAL AND OTHER SUBSTANCES OR MATERIALS, to be as follows:-
My invention relates to improvements on an invention for which a Patent was
granted unto me bearing date 30th January 1882 N° 456.
Under my present invention the roller path described in the patent above
referred to is made so as to be capable of easy detachment for facility of renewal
by unscrewing bolts with T heads by which it is bolted to the main revolving disc.
A ring with a sliding and adjusting face is inserted in the quick revolving disc
in order to allow for the wearing of the operating faces and for replacement as
required. This ring with its adjusting face is set up and kept in position by a
series of set screws and check nuts in the said quick revolving disc.
The roller path is arranged so as to revolve on two or more friction rollers round
the axles of which aro arranged a series of pins or small rollers working on
gudgeons for the purpose of reducing friction.
Similar pins or small rollers are applied to the axes of the crushing or pulverizing
rollers. These rollers are capable of adjustment by means of screws in such a
manner as to admit of one or more of the rollers being put out of action or set at
different distances from the surface of the roller path. By this means the several
rollers may be adjusted so as either to be at an uniform distance from the roller
path or at different distances therefrom thereby allowing the same machine to be
used both for kibbling and pulverizing.
Instead of the collector for the finished material revolving as in the former
machine it is stationary in my improved machine and the material is allowed to
pass downwards by its own gravity and to be conducted through suitable passages
out of the machine at the bottom, the lighter or floating particles of dust being
blown through pipes or outlets (fitted to the said collector) by the force of the
draught caused to be set up through the centre of the slow revolving disc or
roller path by the revolution of the said disc or discs.
The operating faces of the machine are prevented from becoming scored or
worn out of their required truth by giving an excentric motion to the quick
revolving disc at the same time that the roller path is caused to maintain a true

page_text: concentric motion, the said faces being thereby caused to change the relative
positions of their respective operating parts instead of continually acting on the
same parts.
Instead of the mode of feeding described in the former machine if preferred I can
feed the material to be ground through a suitable aperture in the centre of the slow
revolving disc so as to fall against an adjustable plate or diaphragm adapted to
regulate the size of the pieces of material admitted into the machine which pieces
are by the position and form of the diaphragm caused to enter the lower part of
the machine.
The quick revolving disc is adjusted by means of a screw on the main shaft
with one or more adjusting wheels acting on the sleeve or boss of the said disc,
which disc can also be withdrawn by means of such adjusting wheel or wheels as
required for inspecting the interior of the machine.
In other respects besides those above stated the machine is similar to that
described in the specification of my former patent.

page_text: I RICHARD EDMUND SHILL of 79 Harborne Road Edgbaston Birmingham in the
County of Warwick Engineer do hereby declare the nature of my Invention for
"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR KIBBLING AND PULVERIZING
MINERAL AND OTHER SUBSTANCES OR MATERIALS" 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 improvements on an invention for which a Patent was
granted unto me bearing date 30th January 1882. N° 456.
Under my present invention the roller path described in the Patent above
referred to is made so as to be capable of easy detachment for facility of renewal
by unscrewing bolts with T-heads by which it is bolted to the slow revolving disc.
A ring with a sliding and adjusting face is inserted in the quick revolving disc
in order to allow for the wearing of the adjustable or gauging faces and for replace-
ment thereof as required.-This ring with its adjusting face is set up and kept in
position by a series of set screws and check nuts in the said quick revolving disc.
The roller path is arranged so as to revolve on two or more friction rollers round
the axles or gudgeons of which are arranged a series of pins or small rollers
working on gudgeons for the purpose of reducing friction.
Similar pins or small rollers are applied to the axes of the crushing or pulverizing
rollers and also to the sleeve or main bearing of the quick revolving disc. The
pulverizing rollers are capable of adjustment by means of screws in such a manner
as to admit of one or more of the rollers being put out of action or set at different
distances from the surface of the roller path. By this means the several rollers
may be adjusted to the required distance from the roller path so as to allow the
same machine to be used either for "kibbling" or pulverizing.
Instead of the collector for the finished material revolving as in the former
machine it is stationary in my improved machine and the material is allowed to
pass downwards by its own gravity and to be conducted through suitable passages
out of the machine at the bottom, the lighter or floating particles of dust being
blown through pipes or outlets (fitted to the said collector) by the force of the
draught caused to bo set up through the centre of the slow revolving disc or roller
path by the revolution of the said disc or discs.
The adjustable or gauging faces of the machine are prevented from becoming
scored (or worn out of their required truth) by giving an excentric motion to the
quick revolving disc at the same time that the roller path is caused to maintain a
true concentric motion the said faces being thereby caused to change the relativo
positions of their respective parts instead of continually acting on the same parts.
Instead of the mode of feeding described in the former machine if preferred I can
feed the material to be ground through a suitable aperture in the centre of the slow
revolving disc so as to fall against an adjustable plate or diaphragm adapted to
regulate the size of the pieces of material admitted into the machine which pieces
are by the position and form of the diaphragm caused to enter the lower part of
the machine for operation.

page_text: In other respects besides those above stated the machine is similar to that
described in the Specification of my former Patent.
In order that my Invention may be fully understood and readily carried into
effect I will describe it more particularly by the aid of the accompanying Drawings
in which are represented the improvements in “kibbling "and pulverizing
machines or mills above referred to.
DESCRIPTION OF THE DRAWINGS,
Fig: 1 is a longitudinal elevation partly in section and Fig: 2 is an end view
also partly in section shewing the main working parts of the machine or mill. In
these two figures the same letters of reference indicate corresponding parts.
A A are the base plate and standard of the machine B is the main driving shaft
turning in the standard bearing as shewn C is the main structural and slow
revolving disc to which is bolted the roller path D so as to admit of its easy
detachment for renewal as required. This roller path D is caused to revolve on
two or more friction rollers E E which turn on axes fitted with steel pins or rollers
in order to reduce friction supported on adjustable carriages bolted to the bed
plate A. F is the quick revolving disc in which is inserted a ring and face
adjustable to the face of the roller path D by means of a set screw and check nut
as shewn at fin order to allow for the wearing of the faces and renewal as
required. This disc F is mounted on the shaft B as shewn in Fig: 1 or with steel
pins or rollers as shewn detached in Figures 3 and 4 in order to reduce friction.
The disc C is driven at a slower speed than that of the disc F in order to cause the
required differential motion of or between the two discs and thereby keep in
continual motion the material under operation contained in the space or chamber
formed by the interiors of the two discs. These two discs may be driven at their
required relative speeds by any suitable means.
GG are the crushing or pulverizing rollers each mounted on a bell crank lever H
having its fulcrum at h, by means of which lever and the adjusting screw I the
roller may be set at any required distance from the internal surface of the roller
path; J is a spring fitted so as to press on one arm of the lever H with a tendency
to force the roller into contact with the roller path By means of the said adjusting
screws the several rollers may be set to the distance or position adapted either for
"kibbling" or pulverizing as may be required. The pins or fulcra h. h of the
levers H pass through bosses K cast on the quick revolving disc F thereby allowing
of the requisite yielding movement of the rollers G G and their immediate return
by the reaction of the springs J whereby the said rollers are caused to maintain
their crushing and pulverizing force without intermission.
L is a diaphragm which is adjustable by means of set screws M and collars of
various thicknesses in order to regulate the size of the pieces of material to be
"kibbled" or pulverized which are fed into the mouth N in the centre of the
machine from whence they pass down between the diaphragm L and the internal
wall of the disc O on to the inclined internal surface of the roller path descending
which they are ready to be operated upon by the rollers G. G.-O is a stationary
collector into which the pulverized material can pass as it escapes between the faces
of the two revolving discs C and F. This collector is formed as a channel or
passage through which the pulverized material is conducted round the machine
through an opening in the bed plate A and discharged into any convenient
receptacle as indicated by the arrows in fig: 2.
P is an outlet from the collector for dust and light particles with which outlet
may be connected any suitable means for carrying off such dust.
QQ are covers of holes for inspecting and gauging the distances of the faces.
The means for disconnecting the quick revolving disc F are or may be similar to
that employed in the machine under my former patent above referred to.
The excentric motion of the quick revolving disc F is produced by throwing the
centres of the shaft B out at each end after the shaft has been accurately fitted
"

page_text: to the sleeve of the quick revolving disc the said altered centres of the shaft
are for the purpose of turning the cone or that portion of the shaft B that fits
into the conical hole in the boss of the slow revolving disc C.-A bearing is also
turned from the said centres to work in the standard A thereby giving the
required amount of excentricity to the quick revolving disc F while the slow
revolving disc C and the roller path D maintain a true concentric motion from the
axis of the shaft B.-The above described method of providing against the scoring
of the faces is that which I prefer to adopt but the result may be otherwise
obtained.
The working of the machine is as follows: On material being fed into the
machine at the mouth N it will come in contact with the diaphragm L and fall
down between it and the internal wall of the disc C on to the inclined surface
of the roller path D, descending which it will come in contact with the rollers GG
and be crushed and kibbled or pulverized according to the manner in which the
rollers G G are adjusted by means of tho screws II and the bell crank levers H H.-
On the material being thus kibbled or pulverized it will escape through the space
between the duly adjusted faces of the adjustable ring in the quick revolving
disc F and the roller path D (bolted to the slower revolving disc C) and pass into
the stationary collector O whence it will be discharged from the machine in the
direction indicated by the arrows in Fig: 2.-Dust and small particles of material
will escape at the outlet P and be drawn off by any convenient means.
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
The combination of parts constituting a "kibbling" and pulverizing machine or
mill operating in the manner described that is to say the combination of a
detachable roller path an adjustable ring and face inserted in the quick revolving
disc, the means of giving an excentric motion to the quick revolving disc while
maintaining the concentric motion of the roller path two or more friction rollers
for the roller path to revolve on steel pins or rollers applied to the said friction
rollers to the quick revolving disc and to the crushing rollers the means of adjusting
and regulating the pressure and action of the crushing rollers an adjustable
diaphragm to regulate the size of pieces admitted to the roller path and a
stationary collector to receive and discharge the kibbled or pulverized material
with an outlet for dust and small particles all substantially as described.
