PROVISIONAL SPECIFICATION.
An Improved Apparatus for Removing Dust from Air, or the like.
I, LUDWIG RÖSSLER, of Schwanthalerstrasse 51, Munich, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to an improved apparatus for removing dust from air
or the like and in which the dust drawn into the same by a suitable suction ven-
tilator is conducted to a liquid by which it is absorbed.
On the liquid receiver is arranged an eccentrically placed air outlet shaft. The
dust drawn into the apparatus by the section ventilator or inlet is introduced
into the receiver through a preferably vertical pipe. This pipe extends nearly
to the water level and at this point is prolonged by a dome shaped piece. This
under part or dome is arranged to revolve on the upper part and its revolution
is operated by a suitable transmission gearing and bevelled toothed wheels.
In the dome shaped part there is seated a water dispersing wheel. The revo-
lution of this wheel is effected automatically as a toothed wheel seated on the
wheel shaft is conducted along a fixed toothed ring, when the dome is rotated,
and the wheel is consequently put into revolution.
The dispersing wheel consists of several radial arms of wrought iron fixed on
the shaft. The ends of these arms are formed as paddles in order to increase
the dispersing effect.
This wheel disperses the liquid in the dome chamber which is distributed as
spray or minute globules in the water receiver.
In the dome chamber the finer parts of the dust are there mixed with the
spray. The coarser parts of the dust are worked by the wheel under the water
level. Finer dust parts which escape from the dome and try to escape through
the receiver are saturated in the latter by the spray and fall on the liquid.
In order to bring those dust parts which have not been operated on by the
wheel and which float on the liquid under the liquid, and in order to mix them
with the same, there is arranged on the dome a prolongation or nosing dipping
into the liquid on the side, where the paddles of the wheel dip into or approach
the liquid. In the measure in which the paddles remove the liquid in the dome
away from the said nosing, the exterior liquid is drawn under the nosing inwards,
the dust swimming on the exterior liquid is carried into the dome and comes
under the action of the wheel and is mixed with the liquia
In order that all the dust floating around the dome is carried under the wheel,
there is effected the above mentioned mutual revolution of the dome and of the
wheel.
A number or radial paddles may be arranged on the dome which further move
the water for the purpose in view when the dome is revolving.
The air drawn into the dome passes through the liquid receiver through the
outlet shaft into the open air. The air outlet shaft is provided with one or more

page_text: swellings in which there are suspended plates or the like, by the adjustment of
which the air-draught in the shaft can be regulated.
The water evaporizing in the receiver during the hot season or from other
causes can be condensed on the plates and swellings and walls of the shaft and
returned into the receiver through a suitable connecting pipe.

An Improved Apparatus for Removing Dust from Air, or the like.
I, LUDWIG RÖSSLER, of Schwanthalerstrasse 51, Munich, 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 ascer-
tained in and by the following statement:-
This invention relates to an improved apparatus for removing dust from air
or the like and in which the dust drawn into the same by a suitable suction ven-
tilator is conducted to a liquid by which it is absorbed.
In the annexed drawing this device is shown in Fig. 1 in vertical section and
in Fig. 2 in horizontal section. Figs. 3 and 4 show part of the apparatus in two
different views:-
On the liquid receiver a is arranged an excentrically placed air outlet shaft b.
The dust drawn into the apparatus by the suction ventilator or inlet is intro-
duced into the receiver through a preferably vertical pipe c. This pipe c extends
nearly to the water level and at this point is prolonged by a dome shaped piece c¹.
This under part or dome c is arranged to revolve on the upper part and its revo-
lution is operated by a suitable transmission gearing and bevelled tooth wheels j.
In the dome shaped part c¹ there is journalled a water dispersing wheel d. The
revolution of this wheel is effected automatically as a toothed wheel e, on the
heel shaft is carried around a fixed toothed ring f when the dome c¹ is rotated
and the wheel is consequently put into revolution.
The dispersing wheel d consists of several radial arms of wrought iron fixed
on the shaft (Figs. 3 and 4). The ends of these arms are formed as paddles in
order to increase the dispersing effect.
This wheel disperses the liquid in the dome chamber c¹ and the liquid is dis-
tributed as spray or minute globules in the water receiver d.
In the dome chamber c¹ the finer parts of the dust are there mixed with the
spray. The coarser parts of the dust are worked by the wheel under the water
level. Finer dust parts which escape from the dome c¹ and try to escape through
the receiver a are saturated in the latter by the spray and fall on the liquid
In order that those dust parts which have not been operated by the wheel and
which float on the liquid may be brought under the liquid, and in. order to mix
them with the same there is arranged on the dome c¹ a prolongation or nosing 6°
dipping into the liquid on the side, where the paddles of the wheel dip into or
approach the liquid. In the measure in which the paddles remove the liquid in
the dome away from the said nosing, the exterior liquid is drawn under the nosing
inwards, the dust swimming on the exterior liquid is carried into the dome and
comes under the action of the wheel and is mixed with the liquid.
In order that all the dust floating around the dome may be carried under the
wheel the dome and the wheel as above mentioned simultaneously revolve.

page_text: A number of radial paddles g may be arranged on the dome which further
move the water for the purpose in view when the dome is revolving.
The air drawn into the dome passes through the liquid receiver a through the
outlet shaft into the open air. The air outlet shaft b is provided with one or
more swellings in which there are suspended plates i or the like, by the adjust-
ment of which the air draught in the shaft can be regulated.
The water evaporating in the receiver during the hot season or from other
causes can be condensed on the plates and swellings and walls of the shaft b
and returned into the receiver a through a suitable connecting pipe k.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I claim
is;
A. dust extracting apparatus in which the dust is carried to a liquid through
a pipe the domed or enlarged end c¹ of which carries a rotary dispersing wheel
and is itself made to rotate in order to gather the dust from the surface of the
liquid by means of the suction action of wheel and a beak like lengthening of
the dome for mixing it with the liquid the axis of the wheel revolving with the
dome and having a toothed wheel running along a toothed crown for rotating the
wheel, pallets g being also if desired arranged on the circumference of the dome
for agitating the liquid.
