IMPROVEMENTS IN MACHINERY FOR CRUSHING, REDUCING, BREAKING, OR
PULVERIZING, AND MIXING MINERAL AND OTHER SUBSTANCES."
"
Our Invention consists in improvements in machinery for crushing, reducing,
breaking or pulverizing and mixing mineral and other substances, and relates to
that class of machines for this purpose known as edge runners or mortar mills.
One part of the said improvements consists in so constructing and arranging the
supporting or bearing surfaces, in the frame-work of the machine against which
the spindles or spindle-blocks of the rollers or runners or their bearings revolve or
slide as to enable their angle relatively to the vertical axis of the said rollers or
runners to be varied or changed according to the material under treatment and
permit them to be fixed in any required position either for increasing or
diminishing the crushing and pulverizing effect due to the weight of the roller or
runner.
In mills as at present constructed the supporting surfaces of the crushing
rollers or runners are arranged parallel to the vertical axis of the rollers or
runners. The crushing action or force of the latter at command therefore is
dependent solely upon the weight of the roller or runuer. By arranging the said

page_text: bearing surfaces so that they may be adjusted as above described to alter their
inclination relatively to the vertical axis of the rollers or runners the dead weight
of the rollers or runners may be increased or diminished in proportion to the angle
at which the said supporting surfaces are fixed.
One method of carrying this part of our Invention into practice is to form the
said bearing surfaces on or attached to levers suitably pivotted in the frame of the
machine and provided with appropriate means for adjusting and holding them in
position. When this part of our improvements is to be applied to a mill designed
to continually treat any one particular substance this inclined bearing surface
need not be made adjustable and is formed on a block attached to the frame of the
machine.
According to another part of our Invention we arrange the acting or wearing
surfaces of a mill fitted with my improved bearing surfaces for increasing or
diminishing the crushing and pulverizing effect of the rollers or runners, in such a
manner that we are enabled to greatly reduce the expense of wear. For this
purpose we make the wearing parts renewable that is to say, we insert in or
otherwise connect to the periphery of the rollers or runners and the acting surface
of the pan removable wearing surfaces which if desired may be formed in sections
and secured in position by screws or bolts and nuts or otherwise.
When our improved mill is required for crushing and pulverizing the minerals or
other materials in water we prefer to allow the water with the reduced material to
flow through apertures or passages in the central hub of the pan of the machine.
The degree of fineness of the crushed reduced or pulverized material may be
regulated by closing one or more of the said apertures so as to vary the height of
the opening through which the water is allowed to flow away.
According to another part of our Invention we combine with our improved mill
suitable mechanism or apparatus for breaking or reducing large pieces of minerals
or other substances before they are allowed to fall into the pan to be subjected to
the action of the crushing or pulverizing rollers or runners. One method of
carrying this part of our Invention into practice is to arrange the breaker upon the
vertical central shaft or spindle of the machine so that the crushed or broken
material will pass directly therefrom into the pan, but the said breaking or reducing
apparatus may be arranged in any other suitable manner in combination with the
other parts of the machine.
When our improved mill is to be used for crushing and pulverizing dye-wares,
materials for pottery-ware, gypsum, colours, and other similar material it will not
be practicable to use iron or steel for the crushing or pulverizing surfaces on
account of these metals causing discoloration of the said materials.
We therefore form the acting or reducing surfaces of the rollers or runners
and the wearing parts or plates in the revolving pan of phosphor-bronze or
other suitable metals or alloys or of glass or vitrified minerals, granite or stone.
We may provide our improved mill with perforated plates, gratings or sieves
fixed on or attached to the revolving pan.
For the purpose of separating that portion of the material under operation, that
has been reduced to the required degree of fineness, from the coarser particles
which will be caused to pass under the action of the rollers or runners until they
are reduced sufficiently fine to allow them to pass through the perforated plates,
gratings, or sieves.

"IMPROVEMENTS IN MACHINERY FOR CRUSHING REDUCING BREAKING OR
PULVERIZING AND MIXING MINERAL AND OTHER SUBSTANCES."
Our Invention consists in improvements in machinery for crushing, reducing
breaking or pulverizing and mixing mineral and other substances and relate to
that class of machines for this purpose known as edge runners or mortar mills.
One part of the said Invention consists in constructing and arranging in the
framework of the machine the supporting or bearing surfaces against which the
spindles or spindle-blocks of the rollers or runners or their bearings revolve or
slide as to enable the angle of the said supporting or bearing surfaces relatively to
the vertical axis of the said rollers or runners to be varied or changed according to
the material under treatment and permit such supporting or bearing surface to be
fixed in any required position either for increasing or diminishing the crushing and
pulverising effect due to the weight of the roller or runner.
In mills as at present constructed the supporting surface of the crushing rollers
or runners are arranged parallel to the vertical axis of the said rollers or runners,
The crushing action or force of the latter at command is therefore dependent solely
upon the dead weight of the roller or runner. By so arranging the said bearing
surfaces that they may be adjusted to alter their inclination relatively to the
vertical axis of the rollers or runners as above described the dead weight of the
said rollers or runners may be increased or diminished in proportion to the angle
at which the said supporting surfaces are fixed.
One method of carrying this part of our Invention into practice is illustrated in
Figs 1, 2 and 3 of the accompanying Drawings which represent so much of a
crushing or pulverizing as it is deemed necessary to shew to elucidate our
improvements. In these Figures a represents the roller or runner and ¹ is its
axis or spindle. b represents a portion of the revolving pan whereon the said
roller or runner rests. c represents the bearing surface against which the spindle a
rests. In the above named Figures the said bearing surface is shewn as pivotted
upon a pin d upon which it is adapted to be turned. In Figure 1 the said bearing
surface is shewn at right angles to the bed plate b; this is the position occupied by
the bearing surfaces of mills as heretofore constructed and in this position the
acting force at command is simply that due to the dead weight of the roller and
the small amount due to friction.
By lowering the lever whereon the aforesaid bearing surface c is forined so as to
bring the said bearing surface into the position shown in Figure 2 the point of
contact of the surface e with the spindle a will be changed and the weight
of the roller considerably reduced. If however the said lever is moved to the
position shewn in Figure 3 the said bearing surface will occupy such a position
relatively to the spindle a², as to considerably increase the crushing effect of the
roller.
The levers whereon the said bearing surfaces are formed or to which the said
bearing surfaces are attached are suitably pivotted in the frame of the machine
and are provided with appropriate means for adjusting and holding them in
position.

page_text: Fig 4 represents in elevation one arrangement of the said levers in a machine
for crushing or reducing mineral and other substances.
When this part of our improvements is to be applied to a mill designed to
continually treat any one particular substance the aforesaid bearing surface need
not be made adjustable but may consist of an inclined surface upon a block
attached to the frame of the machine as will be readily understood without further
explanation.
For this
According to another part of our Invention we arrange the acting or wearing
surfaces of a mill fitted with our improved bearing surfaces for increasing or
diminishing the crushing and pulverizing effect of the rollers or runners in such a
manner that we are enabled to greatly reduce the expence due to wear.
purpose we make the wearing parts renewable that is to say, we insert in or
otherwise connect to the periphery of the rollers or runners and the acting surface
of the pan removable wearing surfaces which if desired may be formed in sections
and secured in position by screws or bolts and nuts or otherwise.
This part of our Invention is illustrated in front elevation and side elevation in
Figures 5 and 6 of the Drawings.
In these Figures e, e represent the standards of the mill supported on a base-
plate and braced or retained in position at the top by a cross piece as shown.
represents the pan which is fixed to the upright shaft g on the bottom of this
pan is fixed a ring having teeth which gear with and are driven by the bevel-
wheel fixed on the shaft which is supported in bearings on the base plate f
On the said shaft is fixed the pulley 2, by which the pan is driven. The pan is
supported by friction rollers as shown at i.
The upright shaft works in and is supported by a footstep as shewn and is
kept in a vertical position by the aforesaid cross piece at the top of the mill.
The pan is fitted with renewable wearing surfaces for the runners a to
operate on, these runners are built up as shewn that is to say they are fitted with
renewable wearing surfaces a '. A shatt passes through both of the runners
to keep them in their proper relative position.
As the pan revolves it causes the spindles of the runners at a² to come in contact
and be supported by the bearing surfaces c. These bearing surfaces are hinged or
supported on the pin & fixed in the standards or frame e of the mill and the lever
or arm which carries them is attached to the nut of the screw which works in
suitable bearings m in the frame of the machine and is operated by the band-
wheel n.
The position or angle of the bearing surface c can be fixed or regulated
by turning the said scrow l.
When our improved mill is required for crushing and pulverizing the mineral, or
other materials in water we prefer to allow the water with the reduced material to
flow through apertures or passages in the central hub of the pan of the machine.
The degree of fineness of the crushed reduced or pulverized material may be
regulated by varying the height of the opening through which the water is allowed
to flow away.
According to another part of our Invention we combine with our improved mill
suitable mechanism or apparatus for breaking or reducing large pieces of minerals
or other substances before they are allowed to fall into the pan to be subjected to
the action of the crushing or pulverizing rollers or runners. One method of
carrying this part of our Invention into practice is illustrated in horizontal section
in Figure 7 and in vertical section in Figure S of the Drawings. According to the
arrangement therein shewn I arrange the breaker upon the vertical central shaft
or spindle y of the machine as shewn at o so that the crushed or broken material
will pass directly therefrom into the pan b but the said breaking or reducing
apparatus may be arranged in any other suitable manner in combination with the
other parts of the machine.
When our improved mill is to be used for crushing and pulverizing dye-wares,
materials for pottery-ware gypsum colours and other similar materials it will not
be practicable to use iron or steel for the crushing or pulverizing surfaces on

page_text: account of these metals causing discoloration of the said materials. We therefore
form the acting or reducing surfaces of the rollers or runners and the wearing parts
or plates in the revolving pan of phosphor-bronze or other suitable metals or alloys
or of glass or vitrified minerals, grauite or stone.
We may provide our improved mill with perforated plates, gratings or sieves
fixed on or attached to the revolving pan for the purpose of separating that portion
of the material under operation that has been reduced to the required degree of
fineness from the coarser particles which will be caused to pass under under the
action of the rollers or runners until they are reduced sufficiently fine to allow
them to pass through the said perforated plates, gratings or sieves.
Having thus fully described our said Invention and shewn how the same may be
conveniently and advantageously carried into practice we wish it understood that
we claim-
First. The employment in machinery for crushing reducing breaking or
pulverizing and mixing mineral and other substances of adjustable bearing surfaces
or stationary inclined bearing surfaces substantially as above set forth and for the
purposes specified.
Second. Providing the said machinery having such bearing surfaces with
renewable wearing surfaces substantially as above set forth and for the purpose
specified.
Third. The combination with the said machinery having such bearing surfaces of
the means for supplying the same with water and regulating the degree of fineness
of the crushed reduced or pulverized material substantially as above set forth and
for the purpose specified.
Fourth. The combination with the said machinery having such bearing surfaces
of the mechanism or apparatus for breaking or reducing large pieces of material or
other substance prior to their falling into the pan to be subjected to the action
of the crushing or pulverizing rollers or runners substantially as herein set forth.
Fifth. Forming the acting or reducing surfaces of the rollers or runners and the
wearing parts or plates in the revolving pan of material which will not discolor
the substances or inaterials under treatment substantially as above set forth.
In witness whereof I the said Nathan Gold Kimberley have hereunto set my
hand and seal this Eighth day of July One thousand eight hundred and
eighty two.
