Improvements in Stamping Mills for Breaking-up or Reducing Coals
used in Charging Coke Ovens.
I, MORIZ KLEIN, of Krompach-Vasgvar, Hungary, in the Empire of Austria,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in stamping mills for breaking-up or
reducing coals used in charging coke ovens and its object is to improve the con-
struction of the apparatus generally and to increase their working capacity.
The stamping of the coal is to be effected in a similar manner to hand stamping
.e. by the dropping of stampers; the drop of the stamp being independent of the
height of the layer of coal. This is effected as follows:
The shanks of the stamps are pressed by spring rollers or by spring-controlled
rollers, against cam-pieces which for their greater part are circular discs in form
and from which a segment or part has been cut off. The cams are by preference
furnished with leather or the like at their periphery so as to increase the friction
and they are fixed fast on a shaft driven from a motor or any other suitable means.
The discs or rollers are loose upon shafts carried in adjustable bearings. The
rollers or discs may either be elastic or their bearings may be arranged to be
pressed against the shanks of the stampers by suitable springs.
It will thus be understood that at the rotation of the shaft the shanks of the
stamps will be raised by the cams so long as the circular portions thereof are in
contact with the rods, and that as soon as the cut away portion or flat side of the
cam turns towards the shanks the stamps will fall by their own weight. By this
arrangement the height of the drop is entirely independent of the height of the
layer of coal and thus the apparatus is adapted to work in a uniform and continuous
manner under varying conditions. The several stamps are arranged in a line or
series along the stamping box which is constructed in the usual manner with a
removable bottom and with a trench. By arranging each roller to be adjustable
towards the shank of the stamp a more regular action is obtained; this being
impossible with former constructions where all the rollers are mounted on a
common shaft.
The shanks are guided vertically between pairs of rollers the rollers being
arranged at the front and rear and at the sides thereof and thus effectually prevent
the shanks from inclining sideways in any direction. These rollers may be yield-
ingly pressed against the shanks and mounted in adjustable bearings.
.
Upon the spindle of one of the guide rollers, say of each of the stamps.is mounted
a loose brake disc provided with a brake band the ends of which are connected to
a lever. The brake disc is provided with a stop-pawl engaging in the teeth of a
ratchet-wheel rigidly connected with the roller. The teeth of the ratchet wheel
are arranged in a direction allowing the wheel with the rollers to revolve freely
during the up-motion of the stamps, while the rotation of the said wheels and
rollers is prevented by the pawl as the brake disc in connection with the latter
is retained.

page_text: In the frame of the apparatus there is guided a bar furnished with adjustable
stops, the shanks being provided near their lower end at the side facing the cams
with notches or recesses.
If now the bar is so moved as to cause the stops to move the brake-lever rear-
ward and thereby tighten the brake straps upon their dises these latter will be
rciained. If the cam-shaft continues its rotation it will first cause the stamps to
be lifted and then to drop as hereinbefore described.
As the rollers as afore stated rotate freely during the up-stroke of the stamps
and are kept stationary by the pawls and ratchet wheels it will be obvious that
the stamps could only drop by sliding against the peripheral surface of the rollers
but this can be prevented by providing sufficient frictional pressure. Thus the
stamps do not drop on being released by the cam but remain in position until fur-
ther lifted by the cams in their continuous rotation until finally the recesses in
the shanks come against the cams. At this moment the caurs are no longer in
contact with the shanks and these latter remain at rest notwithstanding the con-
tinued rotation of the cams, and thus the operation is interrupted for the charging
of coals.
The apparatus is afterward re-started by withdrawing the bar and so disen-
gaging the brake disc and with it also the rollers whereupon the stamps fall by
their own weight.
By the adoption of adjustable stops upon the bar it is easy to operate any one
or any number of the several stamps to the exclusion of the others.
This is
effected by keeping in their position those of the stops corresponding to the stamps
to be operated so that they operate the levers at the sliding of the bar, while
removing the other stops into a position in which at the sliding of the bar they
cannot affect the corresponding levers.
The shaft is preferably fitted with a fly wheel.

Improvements in Stamping Mills for Breaking-up or Reducing Coals
used in Charging Coke Ovens.
1, MORIZ KLEIN, of Krompach-Vasgyar, Hungary, in the Empire of Austria,
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:-
-
This invention relates to improvements in stamping mills for breaking-up or
reducing coals used in charging coke ovens and its object is to improve the con-
struction of the apparatus generally and to increase their working capacity.
Referring to the accompanying drawing:
Figure 1 is a front-elevation, and
Figure 2 is an end elevation of the improved apparatus.
The stamping of the coal is to be effected in a similar manner to hand stamping
i.e. by the dropping of stampers: the drop of the stamps being independent of the
height of the layer of coal. This is effected as follows:
The shanks 13 of the stamps A are pressed by spring rollers k or by spring-con-
trolled rollers, against cam-pieces i which for their greater part are circular dises,

page_text: fixed or mounted centrally upon shaft h, and from which a segment or part has
been cut-off. The cams are by preference furnished with leather or the like at
their periphery so as to increase the friction. The shaft h is driven from a motor.
or any other suitable means. The discs or rollers k are loose upon shafts d carried
in adjustable bearings I). The rollers or discs & may either be elastic or their
bearings I may be arranged to be pressed against the shanks of the stampers by
suitable springs.
It will thus be understood that at the rotation of the shaft h the shanks of the
stamps will be raised by the cams so long as the circular portions thereof are
in contact with the rods, and that as soon as the cutaway portion or flat side of
the cam turns towards the shanks the stamps A will fall by their own weight. By
this arrangement the height of the drop is entirely independent of the height of
the layer of coal and thus the apparatus is adapted to work in a uniform and con-
tinuous manner under varying conditions.
The several stamps are arranged in a line or series along the stamping box 2
which is constructed in the usual manner with a removable bottom band with a
hopper c. By arranging each roller k to be adjustable towards the shank of the
stamp a more regular action is obtained; this being impossible with former con-
structions where all the rollers are mounted on a common shaft.
These
The shanks are guided vertically between pairs of rollers gg and mm¹ the
rollers being arranged at the front and rear and at the sides thereof and thus effec-
tually prevent the shanks from inclining sideways in any direction.
rollers mm may be yieldingly pressed against the shanks and are mounted in
adjustable bearings oo, and if desired the rollers gg may be arranged in the same
manner.
Upon the spindle of one of the guide rollers, say m, of each of the stamps is
mounted a loose brake disc provided with a brake band p the ends of which
are connected to a lever 2. The brake-disc is provided with a stop-pawl q
engaging in the teeth of a ratchet-wheel rigidly connected with the rollers m.
The teeth of the ratchet-wheel are arranged in a direction allowing the wheel
with the rollers m to revolve freely during the up-motion of the stamps, while
the rotation of the said wheels and rollers is prevented by the pawl 7 as the brake-
disc บ in connection with the latter is retained.
In the frame of the apparatus there is guided a bar a furnished with adjustable
stops r. the shanks B being provided near their lower end at the side facing the
cams with notches or recesses u.
If now the bars is so moved as to cause the stops r to move the brake-lever
rearward and thereby tighten the brake straps p upon their discs p these latter
will be retained. If the cam-shaft h continues its rotation it will first cause the
stamps to be lifted and then to drop as hereinbefore described.
As the rollers m as before stated rotate freely during the up-stroke of the stamps
and are kept stationary by the pawls q and ratchet wheels it will be obvious that
the stamps could only drop by sliding against the peripheral surface of the
rollers m but this can be prevented by providing sufficient frictional pressure.
Thus the stamps do not drop on being released by the cam i but remain in position
until further lifted by the cams in their continuous rotation until finally the
recesses in the shanks come against the cams i. At this moment the cams are
no longer in contact with the shanks and these latter remain at rest notwithstand-
ing the continued rotation of the cams, and thus the operation is interrupted for
the charging of coals.
The apparatus is afterwards re-started by withdrawing the bar s and so disen-
gaging the brake disc and with it also the rollers m whereupon the stamps fall
by their own weight.
By the adoption of adjustable stops r upon the bars it is easy to operate anyone
or any number of the several stamps to the exclusion of the others. This is effected
by keeping in their position those of the stops corresponding to the stamps to
be operated so that they operate the levers at the sliding of the bar s, while

The shaft is preferably fitted with a fly wheel.
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—
1. In an apparatus for disintegrating coal for charging coke ovens the combina-
tion with a number or series of stamps of separate cams, one for each stamp, in
the shape of a circular disc from which a segment or part has been cut off, the
circular portion of the stamp being in contact with the shank of the stamp, and
a separate roller mounted in an adjustable bearing for each stamp, the shank of
which it forces with an elastic pressure against the cam, substantially as herein-
before described.
2. The combination with a series of stamps of friction cams for operating the
same and presser rollers adapted to force the shanks of the stamps with an elastic
pressure against the cams, adjustable guide rollers arranged at the front and rear
and at the sides of the shanks for the purpose of preventing the shanks from
inclining in any direction, substantially as described.
a loose
3. In an apparatus as claimed in Claims 1 and 2, stamps, friction cams for
operating the same, presser-rollers, guide-rollers for the shanks of the stamps,
one of such guide rollers being combined with a ratchet-wheel and pawl,
brake disc, a brake-shoe or band, a lever for operating the brake-block or band
and a bar with an adjustable, or fixed, stop by which the lever is operated in order
to either apply or to loosen the brake, together with means for operating the said
bar; the shanks of the stamps being formed at their lower end and facing the
friction cams with recesses, substantially as and for the purpose specified.
