MACHINERY FOR CRUSHING ORE, STONE, CEMENT, AND SUCH LIKE SUBSTANCES."
A communication from abroad by Friedrich Schiffner, of Obercassel, in the
German Empire.

PROVISIONAL SPECIFICATION left by the said Henry Simon at the Office
of the Commissioners of Patents on the 15th February 1877.
HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVEMENTS IN MACHINERY FOR CRUSHING ORE, STONE, CEMENT,
AND SUCH LIKE SUBSTANCES." A communication from abroad by Friedrich Schiffner,
of Obercassel, in the German Empire.
According to the present Invention a strong lever or jaw is mounted at its lower
end on a fulcrum between two inclined cheeks, the upper end of the jaw having a
rocking motion of limited extent imparted to it, so as to cause it alternately to
approach and recede from each of the cheeks in succession. The spaces between the
jaw and the cheeks being made to taper or decrease in width towards the lower
end, at which point only a narrow space intervenes between the two, any hard
substance placed in such spaces will by the rocking motion of the jaw acting with
considerable leverage and power be crushed as it descends, and will fall through the
narrow openings at the lower end, either in the form of very small pieces, or in a
pulverulent form, according to the size of the said openings, which are adjustable, as
will be presently described.
The jaw and inclined cheeks are confined at the sides by strong side plates
forming a framing, which carries at the lower end a strong pin, on which the jaw
is pivotted, and at the upper end a driving shaft passing through the upper end of
the jaw, and having an excentric which imparts the required limited motion to the
jaw; or the driving shaft might be mounted at one side of the framing, and the
motion of its excentric or crank be imparted to the jaw by means of a connecting
rod. The upper ends of the inclined cheeks are also pivotted on strong transverse
bolts carried by the framing, while the lower ends rest upon wedge-shaped sliding
blocks that can be moved by adjusting screws nearer to or farther away from the
lower end of the rocking jaw, thus moving the lower ends of the cheeks in a

page_text: corresponding manner, and thereby regulating the width of the openings between
the cheeks and the jaw.
If required an elastic packing may be placed between the surfaces of the lower
ends of the cheeks and the regulating blocks which support them, so that the
cheeks can yield somewhat to any excessive strain caused by the presence of a
piece of iron or other material that resists the crushing action. The acting faces of
the jaw and the cheeks may be provided with removable plates of steel or iron that
can be renewed in case of their being injured.
The acting surfaces of the jaw and cheeks may be either plane or curved surfaces,
and they may be either smooth or formed with teeth or projections.
The rocking jaw may be made adjustable vertically, its trunnions being carried
in adjustable supports, in which case the excentric that imparts, motion thereto
would work in a block adjustable in a slotted hole in the upper end of the jaw.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Henry Simon in the Great Seal Patent Office on the 8th August
1877.
HENRY SIMON, of No. 7, St. Peter's Square, Manchester, in the County of
Lancaster. "IMPROVEMENTS IN MACHINERY FOR CRUSHING ORE, STONE, CEMENT,
AND SUCH LIKE SUBSTANCES." A. communication from abroad by Friedrich Schiffner,
of Obercassel, in the German Empire.
According to the present Invention a strong lever or jaw is mounted at its lower
end on a fulcrum between two inclined cheeks, the upper end of the jaw having a
rocking motion of limited extent imparted to it, so as to cause it alternately to
approach and recede from each of the cheeks in succession. The spaces between the
jaw and the cheeks being made to taper or decrease in width towards the lower
end, at which point only a narrow space intervenes between the two, any hard
substance placed in such spaces will by the rocking motion of the jaw, acting with
considerable leverage and power, be crushed as it descends, and will fall through
the narrow openings at the lower end, either in the form of very small pieces or in
a pulverulent form, according to the size of the said openings, which are adjustable,
as will be presently described.
The jaw and inclined cheeks are confined at the sides by strong side plates
forming a framing, which carries at the lower end a strong pin, on which the jaw is
pivotted, and at the upper end a driving shaft passing through the upper end of the
jaw, and having an eccentric, which imparts the required limited motion to the
jaw; or the driving shaft might be mounted at one side of the framing, and the
motion of its eccentric or crank be imparted to the jaw by means of a connecting
rod. The upper ends of the inclined cheeks are also pivotted on strong transverse
bolts carried by the framing, while the lower ends rest upon wedge-shaped sliding
blocks that can be moved by adjusting screws nearer to or farther away from the
lower end of the rocking jaw, thus moving the lower ends of the cheeks in a
corresponding manner, and thereby regulating the width of the openings between
the cheeks and the jaw.
If required an elastic packing may be placed between the surfaces of the lower
ends of the cheeks and the regulating blocks which support them, so that the
cheeks can yield somewhat to any excessive strain caused by the presence of a
piece of iron or other material that resists the crushing action. The acting faces
of the jaw and the cheeks may be provided with removeable plates of steel or iron
that can be renewed in case of their being injured.
The acting surfaces of the jaw and cheeks may be either plane or curved surfaces,
and they may be either smooth or formed with teeth or projections.
The rocking jaw may be made adjustable vertically, its trunnions being carried.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 represents a longitudinal, and Fig. 2 a transverse section of a crushing
machine according to this Invention, and Fig. 3 is a sectional plan showing the
lower part thereof.
A is the lever or jaw, which is caused to reciprocate on a fulcrum bolt a at its
lower end by means of the eccentric B revolving in a sliding bush 6 in its upper
end. On each side of the lever A is a cheek C pivotted on a bolt c at its upper end,
and resting at its lower end on a sloping block D, which can be slid inwards or
outwards by an adjustable screw d. The lever A and the cheeks C are preferably
made with removeable faces E, which can be taken out when worn or broken, and
new faces can be substituted for them. The lever A may be covered, as shewn by
a hood F, and side plates G may be fixed over the cheeks C; a double mouthed
hopper being thus formed for feeding the material H to be operated on; K, K, are
the sides of the machine, enclosing the working parts between them. It will be
seen that as lumps of the material are fed in at the top of the machine they become
crushed between the jaws, being reduced smaller and smaller as they descend, and
delivered at the bottom in pieces of such size as is determined by the adjustment
of the blocks D, holding the cheeks C more or less close to the reciprocating
lever A.
Although the lever A is shewn in the Drawings to be worked by an eccentric on
a shaft passing through it, it is obvious that it might be worked by a connecting
rod from a crank or eccentric on a shaft apart. Also the crushing faces E, E,
instead of being straight, as shewn, might be more or less curved or serrated,
according to the nature of the material which they are intended to operate on.
Having thus described the nature of this Invention, and in what manner the
same is to be performed, as communicated to me by my foreign correspondent, I
claim, the construction of a crushing machine, wherein a middle lever or jaw
pivotted at its lower end is caused to reciprocate between two cheeks pivotted at
their upper ends, and resting at their lower ends on adjustable wedge blocks,
substantially as herein described.
In witness whereof, I, the said Henry Simon, have hereunto set my hand
and seal, this Twenty-eighth day of June, in the year of our Lord One
thousand eight hundred and seventy-seven.
