Improvements in or relating to Fulling Machines.
I, MAX KEMMERICII, of Friedrichstrasse 87, Aix-la-Chapelle, in the Empire
of Germany, Civil 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:
The present invention relates to an improved cylinder fulling machinė com-
prising three cylinders. The two upper cylinders are mounted on pivotted or
swinging levers, and are provided with suitable means for exercising pressure
upon them, the adjustment of the weights or pressing devices being easily
effected by an attendant, by means of a hand-wheel or lever provided in an easily
accessible place. Each upper cylinder is also provided with a device for regulating
its height or position relatively to the main cylinder, so as to enable the atten-
dant to regulate the more or less energetic action on the cloth-according to
its quality by means of hand-wheels or the like located on the machine. In
order to avoid possible damage owing to insufficient movement of the cloth,
caused by the cylinders, the machine is also provided with a stop motion
apparatus and finally, the cylinders are positively rotated by suitable gearing.
Owing to these improvements it is possible with the machine described above
to treat material of any kind in the most suitable manner, and to obtain a
maximum production and efficiency.
In the accompanying drawings:
Figure 1 represents a side view,
Figure 2 a front view of the new fulling machine, and Figure 3 a detail view
of the stop motion device.
The two upper cylinders 1 are mounted in supporting levers or arms 2
pivotted on a shaft 3 (Figure 1), the supporting arms 2 being connected with
links 5, which transmit the effect of the adjustable pressure weights 10 to the
cylinders. For this purpose two shafts 6 carried in suitable bearings, are pro-
vided towards their centres with weight supporting levers 7, and at their ends
with arms 8, the latter being connected by means of bolts 9 with the links 5.
The levers are provided with movable weights 10, which can be adjusted by
means of chains or the like from hand-wheels 11 situate at a convenient place
in the frame. The hand-wheels 11 can be fixed in the adjusted position by
means of screw clamps 12.
Each arm 2 is connected not only to the link 5, but also to one end of a
double armed lever 14 by its pin 4 engaging in a longitudinal slot in said lever,
which carries at its upper end a block 15 which can easily slide up and down
on a rod 16. Springs 17 are arranged round the rods 16 between the blocks
and nuts or caps on said rods. Each rod 10 is provided at its lower end with
a screw thread engaging in a sleeve 18 provided with teeth gearing with a
worm on a shaft 19 provided with a hand-wheel 20, by means of which the rods
can be raised or lowered. Owing to this arrangement, when the upper cylinders
descend, the blocks 15 press more or less strongly against the springs 17 thereby
adjusting the distance between the upper cylinders 1 and the lower cylinder 21.
The greater the distance between the cylinders the less will be their effect on
the cloth

page_text: The cloth before entering between the cylinders is carried over a friction
cylinder 22. This cylinder actuates by means of bevel gearing, a governor 23
connected by a pivotted lever 24, and a rod 25 with a stop motion lever 20.
The latter is connected at 27 to the upper arm of an un-coupling device 28
which is pivotted at 29 to a bracket on the frame of the machine. This pivotted
lever 28 is provided with a slot at its one end in which engages the end of the
belt shipping lever 30. On a shaft 31 are keyed two crank arms 32 and 33,
the arm 33 being connected by a rod 36 to an eccentric 34, mounted on the
principal shaft 35, in such a manner that for every revolution of the shaft the
lever 32 is caused to swing to and fro on its pivot. The lever 32 is therefore
constantly reciprocating. At its free end it is preferably provided with a toothed
plate or projection 37 adapted to engage the lever 26 when it is raised into its
path of reciprocation. When the plate 37 strikes against this lever it turns the
stop motion lever 28 about its axis 29 thereby allowing the rod 30 to be drawn
back by a spring 38 into the un-coupling position, the belt shifter being mounted
on rods 40 and is provided with a slot for the reception of the rod 30.
By means of the stop motion device it is possible to adjust the mechanism
according to the quality of the material to be treated, in such a manner that it
will act only in certain positions of the governor arms.
It is well known that
to a certain extent the sliding of the fulling cylinder does not damage the cloth,
it would therefore be unnecessary and result in loss of time if the stop motion
came into play on such an occasion. It would however be a mistake if the stop
motion acted only after the friction roller had been, completely stopped, because
in that case damage to the cloth would already have been done The adjustment
is obtained in a very simple way by regulating the length of the rod 25 by
means of a central sleeve with right and left handed screw threads. The belt
shifting rod 30 is pivotted at 39 and actuates in the ordinary manner the belt
shifter 41 movably arranged on the pins 40.
In cylinder fulling machines it is absolutely necessary to obtain good results,
that the cylinders should be geared with the main cylinder in such a manner
that the peripheral speed of the cylinders should always remain constant.
This gearing cannot be obtained by means of bands or ropes, inasmuch as slip
on the part of the upper cylinders could not be avoided in cases of strong pres-
sure, owing to which the upper cylinders would sometimes carry forward the
cloth insufficiently or possibly not at all.
In the present fulling machine this positive gearing is obtained by an arrange-
ment according to which the upper cylinders can oscillate around an auxiliary
shaft as a centre which shaft is operated, by means of chain gearing, by the
lower cylinder, and transmits the rotary motion by means of toothed wheels to
the upper cylinders. The auxiliary shaft 3 is arranged above the lower
cylinder 21 and is also provided on both sides of the machine with the swinging
levers 2, the ends of which support in bearings the shaft 42 of the upper
cylinders 1. Each shaft 42 is provided on one side with the toothed wheel 43
gearing with the toothed wheel 44 keyed on the shaft 3. The shaft 3 is also
provided with a chain wheel 45 actuated by means of a steel chain 47 by a
similar chain wheel 46 keyed on the shaft 35 of the lower cylinder 21. The
fabric is fed forward by friction between the cylinders 1 and 21.
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. A cylinder fulling machine in which the pressure cylinder is weighted by
a movable weight which is movable by means of a chain and operating handle
substantially as described.
2. In a cylinder fulling machine apparatus for adjusting the height of the
pressure cylinder or cylinders, in which the pivot of the pressure cylinder,
provided with an adjustable weighting device, is connected with a double arm

page_text: supporting lever, the oscillation of which can be adjusted by the combined action
of a rod, preferably provided with a spring as 17, and means for raising and
lowering said rod substantially as described.
3. In a cylinder fulling machine of the kind described, a stop motion device
for automatically stopping the machine whenever the cloth is insufficiently
carried forward, comprising a governor actuated by a friction roller over which
the cloth passes, and a lever 26, connected to the belt shifting mechanism, by
an adjustable rod, said lever being adapted to be moved into the path of a
constantly reciprocating lever, as 32, substantially as described.
4. In a cylinder fulling machine the arrangement, for the purpose of obtaining
a positive gearing of the pressure cylinders of bearings for the latter in levers
mounted concentrically round an auxiliary shaft driven by the main cylinder by
chain gearing substantially as described.
5. In a cylinder fulling machine, a main cylinder, pressure cylinders, driven
thereby, a central shaft levers, as 2, on said shaft and carrying said pressure
cylinders, links, as 5, and adjustably weighted levers, as 7, substantially as
described.
6. The complete cylinder fulling machine substantially as described or illus-
trated in the accompanying drawings.
