PROVISIONAL SPECIFICATION.
Improved Machine for Beating Carpets and other Fabrics.
We, PAUL KUBICA, Engineer, of IX Strassnitzkygasse, No. 8, LEOPOLD
SWATOSCH, Engineer, of II Klosterneuburgstrasse No. 5, and CARL WALDMANN,
Gentleman, of II Blumauergasse, all of Vienna, Austria, do hereby declare the nature
of this invention to be as follows:-
This invention relates to an improved construction of beating machine for beating
carpets and other fabrics, whether for cleansing the same of dust, or for other
purposes. The said machine is constructed as follows:-
A roll of the carpet or other fabric to be treated, is placed in a trough fixed to the
framing machine, and the edge thereof is passed through a feed roller, driven from
the main shaft by means of a bevil wheel and opposite bevil pinions on a countershaft,
either pinion being slid into gear with the wheel, according as the feed roller
requires to be rotated in one direction or the other. The feed roller feeds te fabric
down an inclined grating consisting of a series of parallel bars placed obliquely to
the travel of the fabric.
In the spaces between these bars are correspondingly obliquely placed straps
which, as the carpet passes over them, are alternately jerked from a loosely hanging
looped position in an upward direction against the underside of the fabric, so as to
strike this sharply and thus beat out the dust therefr m. This motion of the straps
is effected as follows: In the lower part of the machine is a shaft driven from the
mainshaft and carrying a number of tappets or cams, each of which acts on the one
arın of a three-armed lever these levers being mounted in a row loose on a shaft on
one side of the framing. One of the other two arms is connected to an adjustable
helical spring, which, as the first named arm, after being depressed by the tappet, is
released thereby, rapidly draws the lever back into its original position; the third
arm is connected by a rod to one end of a double ended lever on a pivot just below
the above mentioned grating, the other end of such lever being attached to the one
end of the said strap. Thus on the sudden backward motion being imparted to the
three arned lever by the spring, the former in imparting such motion to the upper
lever, causes this to jerk the strap upward from its loosely hanging position, so as to
strike the fabric as described.
The other end of the strap may either be attached to a fixed point, or to a similarly
actuated lever.
For regulating the strength of the blow according to the nature of the fahric
treated the shaft carrying the three armed levers, is carried in bearings mounted in
excentrics, so that, by turning the latter by a hand lever, the axis can be moved
nearer to or farther from the tappet shaft, and thus the action of the latter on the
levers be increased or decreased. Also, the action of each lever can be independently
regulated by adjusting the tension of t'e spring connected thereto.
At the lower end of the grating is a pivotted inclined table, which lea !s the fabric
over a cylindrical rotary brush, that brushes the underside of the carpet as it passes
over it, the table being capable of being raised or lowered, so as to cause the fabric to
be brought into more or less intimate contact with the brush, or to be raised so as
not to come in contact therewith at all.

page_text: When the carpet has been entirely passed over the beating and brushing devices, it
can be subjected to their action a second time by simply reversing the rotation of
the feed motion as first above mentioned.
The space below the grating is enclosed by a casing with inclined bottom, on to
which the coarser particles of dust from the fabric fall and whence they slide down
into a trough containing a revolving conveying worm which conveys the dust into
receptacles at one end.
The lighter dust is drawn off both from below and from above the grating, by two
exhaust channels communicating with an exhaust fan, which propels the dust into
a chamber, one or more sides or the top of which are made of permeable fabric,
that allows the air to pass, but retains the dust.
In the channel leading from the fan to the dust chamber is preferably arranged
a water spraying device for moistening the air and dust and thus prevents this
from flying about excessively; such water may also contain a suitable disinfectant.
The water may be supplied from a tank at the top of the machine and an air pump
worked by the driving shaft supplies the necessary air blast for spraying.

Improved Machine for Beating Carpets and other Fabrics.
We, PAUL. KUBICA, Engineer, of IX. Strassnitzkygasse No. 8, LEOPOLD SWATOSCH,
Engineer, of II. Klosterneuburgstrasse No 5, and CARL WALDMANN, Gentleman, of
II. Blumauergasse, all of Vienna, Austria, 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 an improved construction of beating machine for heating
carpets and other fabrics, whether for cleaning the same of dust or for other purposes.
We will describe the construction of the said machine with reference to the
accompanying drawings, in which
Figure 1 shews a cross section,
Figure 2 a sectional side elevation, and
Figure 3 a sectional plan.
The carpet or other fabric to be treated is laid in a rolled condition in the trough 1
and its edge is brought under the feed roller 2 which is driven from the main shaft 6
through a worm wheel 4 and bevil reversing gear 5, 5, 5.
The beating device consists of a shaft 7 carrying cans or wipers 8 that are helically
arranged round the shaft. This is driven from shaft 6 by means of belt pulleys 9 and 10,
and its wipers 8 act upon the arms 11 of the three-armed levers 11, 12, 13 mounted
loose on a shaft 14. To the arms 12 are attached adjustable springs 15 which serve
to bring the levers into their normal position; the arms 13 are pivoted to rods or
straps 16 that actuated two-armed levers 17, 18.
The upper arms 18 of these levers serve for the attachment of one end of the
straps 19 that effect the beating operation, the other ends thereof being fixed
at 20.
If desired these ends might however also be actuated in the same manner as those
first named. When the lever 11 is actuated by the revolving wiper 8 the lever 12
puts an increased strain on the spring 15 and at the same time the lever 13 is moved

page_text: in such a direction as to slacken the strap 19 which it has held tant before, causing
it to hang loose as indicated by the dotted line in Figure 1. On the wiper 8 releasing
the lever 11, the spring 15 in drawing lever 12 backward causes 13 to exert a sudden
downward pull upon 17, whereby lever 18 is made to jerk the strap 19
upward so as to strike against the carpet which is travelling down on a
grating 21.
The straps 19 are arranged under the spaces het ween the hars of the grating, and,
like these are arranged obliquely relatively to the direction of travel of the carpet,
as shewn in the plan at Figure 3, by which arrangement it will be seen that the
beating straps will come in contact with every portion of the carpet.
The carpet, after being beaten in the above described manner, then slides farther
down the inclined plane 22 and comes in contact with the cylindrical brush 29, which
brushes it on the underside. This inclined table 22 is pivoted so as to have its angle
adjusted in order to bring the carpet more or less closely in contact with the brush or
to raise it entirely out of contact therewith, The brush 23 is driven from the shaft 6
by means of the belt pulleys 25 24. If the carpet requires to be beaten a second time,
then as soon as its rear end has reached the feed roller 2 the position of the pinions
of the bevil reversing gear 5 is reversed, the upper pinions 5, being put in gear with
the bevil wheel while the lower one is thrown out of gear. The feed roller is thus
driven in the contrary direction so as to cause the carpet to travel backward over the
grating, the beater-straps and brush continuing their action as above described, The
coarse dust that is separated from the carpet by the beating slides down the
inclined table 26 into a gutter 27 where it is conveyed by a worm 28 into a collecting
sack 29.
The spaces above and below the grating 21 are connected with each other by a
channel 30 which extends to an exhaust fan 31 driven by belt and pulley genring 88, 39,
by means of which the light dust is sucked off from those spaces and is delivered into
a chamber 32. In the channel 30 is provided a water-spraying device of any suitable
known arrangement which moistens the dust as it passes through.
If desired, some suitable disinfectant can be mixed with the water-spray.
The upper part 33 of the dust. chamber 32 is advantageously provided with a
permeable fabric covering for allowing the escape of the air blown in, while retaining
the dust,
For producing the water-spray an air pump 34 and water tank 35 are provided on
the machine.
In order to regulate the strength of blow of the beating straps according to the
nature of the fabric operated upon, the shaft 14 is mounted in eccentric bearings 30
which can be turned by means of a hand lever 37 so as to bring the shaft 14 nearer to
or farther from the shaft 7 and thus cause the action of the wipers 8 upon the lever
arms 11 to be stronger or weaker.
This adjustment can be effected while the machine is at work. In addition to this,
the tension of the springs 15 can be separately adjusted for regulating the strength of
stroke of each strap. Lastly, the straps 19 can have weights attached to them for
increasing their action.
Having
particularly described and ascertained the nature of this
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. A beating machine consisting of a grating with diagonal bars, 21, in combination
with beating straps 19 situated between the hars of the grating and connected at one
or both ends to lever arms 18 actuated by the arm 13 of a three-armed lever, whose
second arm 12 is acted upon by a spring 15 while the third arm 11 is acted upon by
a revolving wiper 8 so as to cause the arm 18 to impart an upward jerking motion to
the strap 19, substantially as described.
2. In a beating machine such as is referred to in the first claim, mounting the
shaft 14 carrying t':e three-arined levers 11, 12, 13, in eccentric bearing 36, by the

page_text: adjustment of which the blow of the beating strap 19 can be regulated, substantially
as described.
3. In a beating machine such as is referred to in the first claim, the combination,
with the spaces above and below the grating 21, of a channel 30 leading to an exhaust
fan 31 for exhausting the dust from such spaces and discharging it, after being
subjected to a water spraying device, into a dust chamber 32 substantially as
described.
4. In a beating machine such as is referred to in the first claim, the combination,
with the grating 21, of an incline table 26 an I collecting trough 27 with transporting
worm 28 for removing the coarse dust, substantially as described.
