PROVISIONAL SPECIFICATION.
Improvements in Machines for Crushing Stone, Ores, and the like.
I, MARIE EUGÈNE VILLEROY of Schramberg Würtemberg in the Empire
of Germany, Manufacturer, do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in machines for crushing ores, stones or
like material, and the object of the same is to obtain a greater uniformity in the
size and form of the particles of the reduced material than in the machines of this
kind heretofore in use.
The main feature of my invention consists in the employment of two horizontally
moveable crushing jaws arranged one above the other within the frame of the
machine, so that the material reduced by the upper jaw will drop between the
lower jaws and be subjected to further crushing action before it leaves the machine.
These jaws are however actuated in opposite direction, so that while the lower
moveable jaw performs its out-stroke the upper one is moved into its initial position
and vice versu.
According to my invention I employ a pair of moveable jaws, which are guided
by means of suitable guide-plates rigidly connected to the frame of the machine.
At their rear end, each of the said moveable jaws is provided with an oblique surface
which are inclined to each other at an obtuse angle corresponding with that of the
surfaces of a sliding block which serves to actuate the said moveable jaws by its
up-and-down motion in a vertical path formed at both sides by the frame of the
machine itself and at the rear end by adjustable wedges or keys. The up-and-
down motion of the sliding-block is caused by an eccentric or cam of a horizontal
shaft journalled in suitable bearings of the frame of the machine and provided:
with a driving pulley and at each end with a fly-wheel. The said eccentric or cam
extends through the said sliding block but it may be lined with a case-hardened or
chille. bushing in order to reduce the friction on the pressure faces of the said
sliding-block.
On the ascending motion of the said sliding block the upper moveable crushing jaw
is forced towards the corresponding stationary jaw within the machine-frame. As
however the said horizontally moveable jaws are both connected through rods to a
double armed lever having its fulcrum at the rear end of the frame of the machine,
the motions of the jaws depend upon each other, so that both are simultaneously
moved in opposite directions. While therefore the upper moveable jaw is in action
the lower one is drawn back by means of the said double armed lever into its
initial position and vice versa. By means of the wedges or keys which support the
sliding block at its rear face the grasping capacity of the jaws may be adjusted at
desire.
In a somewhat modified construction the moveable jaws are not guided in a straight
line, but oscillated about horizontal pivots resting one above the other in suitable
bearings of the frame of the machine. In this case the jaws are subjected to the
action of a vibrating beam the notion of which is caused similarly to that of the
sliding block of the heretofore described machine by an eccentric or cam of a
horizontal shaft journalled in suitable bearings of the frame and provided with the
necessary driving pulley and fly-wheels. This eccentric which may be also lined
with a chilled bushing extends through a suitable aperture of the said vibrating
beam. The latter, having its fulcrum on a shaft eccentrically journalled in the
lower part of the machine frame serves to alternately actuate the oscillating jaws
through the medium of a pair of toggle-plates which engage suitable recesses of the
moveable jaws and the said vibrating beam. In order to perform the desired

page_text: alternate oscillating motion of the said jaws the axis of the pivot of the vibrating
beam is placed in vertical direction between the said recesses of the latter, so that
the same may act as a double-armed lever in relation to the movable jaws.
The vibrating beam is provided with sufficiently wide passages for a pair of rods
of which either one is connected at one end to one of the said oscillating jaws and
at the other end to a double armed lever pivoted to the rear side of the machine
frame. This is designed for the purpose of transmitting the oscillating motion of
one of the jaws to the other and to perform a reciprocal action of the same.
The degree of fineness to which the material fed between the crushing jaws is
to be reduced depends upon the adjustment of the said eccentrically journalled
shaft the position of which may be altered by turning the eccentric journals of the
same within their bearings, which may be effected through the medium of a wrench
put on the square at one or both ends of the said shaft.
By means of the machines provided with my described improvements not only
broken stones.of about 2 inches diameter may be produced, but also the material
reduced to the fineness of gravel and sand, the whole out put of the machine is of
uniform condition or size of the single pieces, so that the material once crushed
need not be repeatedly passed through the machine as heretofore required in other
machines of this type.

COMPLETE SPECIFICATION.
Improvements in Machines for Crushing Stone, Ores, and the like.
I, MARIE EUGENE VILLEROY, of Schramberg, Würtemberg, in the Empire
of Germany, Manufacturer, 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 improvements-in machines for crushing ores, stones or
like material; and the object of the same is to obtain a greater uniformity in the
size and form of the particles of the reduced material than in the machines of this
kind heretofore in use.
I attain this object by the mechanism illustrated in the accompanying drawings,
in which
.
Figure 1 is a sectional side elevation and
Figure 2 a plan partly in horizontal section of my improved crushing
machine.
Figures 3 and 4 are similar views of a modification.
The main feature of my invention consists in the employment of two horizontally
movable crushing jaws arranged one above the other within the frame of the
machine, so that the material reduced by the upper jaw will drop between the
lower jaws and be subjected to further crushing action before it leaves the machine.
These jaws are however actuated in opposite direction, so that while the lower
movable jaw performs its out-stroke the upper one is moved into its initial position
and vice versa.
In the machine shown in Figures 1 and 2 a a are the movable jaws, the upper
one of which is guided by means of a guide-plate 6 and the lower one by means of a
guide plate d, both being rigidly connected to the frame of the machine. At their
rear end, each of the said movable jaws is provided with an oblique surface a a
which are inclined to each other at an obtuse angle corresponding with that of
the surfaces e el of a sliding block e which serves to actuate the said movable
jaws a a by its up-and-down motion in a vertical path formed at both sides by the
guide way c'e' of the frame c at the rear end by adjustable wedges or keys p. The

page_text: up-and-down motion of the sliding block e is caused by eccentric or cam ƒ of
the horizontal shaft i journalled in suitable bearings of the frame c and provided
with a driving pulley and at each end with a fly-wheel g. The eccentric /
extends through the sliding-block e but it may be lined with a case-hardened or
chilled bushing k in order to reduce the friction on the pressure faces e³ e' of the
said sliding block e.
On the ascending motion of the said sliding-block e the upper movable crushing
jaw a is forced towards the corresponding stationary jaw within the frame c.
As however the said horizontally movable jaws a a are both connected through
the rods m and m' to a double armed lever n having its fulcrum o at the rear end
of the frame e of the machine, the motions of the jaws depend upon each other, so
that both are simultaneously moved in opposite directions. While therefore the
ipper movable jaw a is in action the lower one is drawn back by means of the
lever n into its initial position and vice versa. By means of the wedges or keys p
which support the sliding block e at its rear face the grasping capacity of the jaws
may be adjusted as desired.
In the somewhat modified construction, Figures 3 and 4, the movable jaws A A
are not guided in a straight line, but oscillated about horizontal pivots q resting
one above the other in suitable bearings of the frame c of the machine. In this
case the jaws A A are subjected to the action of a vibrating beam the motion of
which is caused similarly to that of the sliding-block e of the heretofore described
machine by an eccentric or cam of a horizontal shaft i journalled in suitable
bearings of the frame c and provided with the necessary driving pulley and
fly-wheel g.
of
This eccentric which may be also lined with a chilled bushing & extends through
a suitable aperture of the vibrating beam r The latter, having its fulcrum on a
shafts eccentrically journalled in the lower part of the frame c, serves to alter-
nately actuate the oscillating jaws A A through the medium of the toggle-
plates which engage the recesses A' A' of the movable jaws and those
the vibrating beam r. In order to perform the desired alternate oscillating motion
of the jaws A A the axis of the pivots of the vibrating beam is placed in a
vertical direction between the recesses of the latter, so that the same may act as
a double-armed lever in relation to the movable jaws A A.
The vibrating beam is provided with sufficiently wide passages for the
rods m² m² of which either one is connected at one end to one of the oscillating
jaws A A and at the other end to the double armed lever N¹ piroted at o' to the
rear side of the machine frame c. This is designed for the purpose of transmitting
the oscillating motion of one of the jaws A A to the other and to perform a
reciprocal action of the same.
The degree of fineness to which the material fed between the crushing jaws is to
be reduced depends upon the adjustment of the eccentrically journalled shaft s the
position of which may be altered by turning the eccentric journals s² of the same
within their bearings, which may be effected through the medium of a wrench put
on the square s' at one or both ends of the shaft s.
By means of the machines provided with my described improvements not only
broken stones of about 2 inches diameter may be produced, but also the material
reduced to the fineness of gravel and sand; the whole output of the machine is of
uniform condition or size of the single pieces so that the material once crushed
need not be repeatedly passed through the machine as heretofore required in other
machines of this type.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. A machine for crushing ores, stones and like material having two alternately
actuated jaws arranged one above the other, which are simultaneously moved in
opposite directions, substantially as and for the purposes set forth.

page_text: 2. In a machine for crushing ores, stones and like material having two alter-
nately actuated jaws one above the other each provided at its rear end with an
oblique surface which are inclined to each other at an obtuse angle, the combi-
nation, with a sliding block having correspondingly inclined surfaces and having
imparted thereto a to-and-fro motion in a direction rectangular to that of the said
jaws, substantially as, and for the purpose set forth.
3. In a machine for crushing ores, stones and like material having two alter-
nately actuated jaws moved horizontally one above the other, the combination of
the frame c provided with the stationary jaws 1, the movable jaws a, the sliding

move up and down by means of a rotating eccentric or cam f, and of the double.
armed lever n pivoted at the rear end of the frame c and connected to the movable
jaws a by means of rods m m³ substantially as and for the purpose set forth.
4. In a machine for crushing ores, stones and like material having two alter-
nately actuated jaws suspended by pivots one above the other within the frame of
the machine, the combination with a vibrating beam and a pair of toggle-plates
which engage suitable recesses of the jaws and the said vibrating beam, substantially
as and for the purpose set forth.
