screen or ?lter member is partly submerged or
5 caused to dip into a bath of washing liquid.
Air cleaners of this type have heretofore been
designed in the form of a revolving screen, the
lower arc of which is caused to pass through a
bath of oil or other washing liquid as the screen
10 is slowly revolved by an electric motor. In the
constructions heretofore designed, the driving
mechanism and its parts have been quite intri
cate and expensive to manufacture and, by
reason of the electric drive, the storage battery is
15 subjected to a further drain over and above that
to which it is already subjected in the present
day motor vehicles.
Air cleaners of this general design have been
used as a part of the equipment for tractors and
2O other motor vehicles which are frequently placed
in operation in territories in which the air is
often ?lled with clouds of dust, and it is there
fore essential that the cleaner operate e?iciently
so as to remove the ?ne particles of grit before

This invention relates to an air cleaner for
passage into the engine cylinders.
The present invention has for its object to
provide an improved cleaner unit in which the
air- cleaning function is performed in a more
satisfactory and e?icient manner, and further
30 to provide a unit wherein the power for its op
eration is derived from the low pressure or suc
tion in?uences induced in the operation of the
motor vehicle engine.
In the drawing, Fig. 1 is a longitudinal section
35 through the air cleaner unit, depicting one em
bodiment of the present invention.
Fig. 2 is a transverse section through the unit
in the plane of the screen.

the screening cylinder extends into a bath of oil
or other washing liquid, and in order to increase 1 O
the wet surface area over which the dust laden
air is to pass, the periphery of the cylinder is
provided with a series of outstanding rings or
plates I 0. The cylinder is slowly rotated when
in operation and consequently freshly washed 1;
surface portions of the cylinder and its plates
l0 are continuously rising from the bath within
the housing 6 and into the path of the in?owing
air. The dust laden surface areas of the screen
ing member are at the same time being im- 20
mersed in and carried through the washing liq~
uid to be cleansed of the collected particles of
dust. A ba?le plate II is provided to insure
proper directional ?ow of air through the cyl
inder.

According to the present invention, an air
motor is utilized for slowly revolving the clean
ing cylinder, the drawing showing a turbine type
air motor which has a chambered casing I2 and
a rotor I3. The rotor is provided with a hub I4 30
which is journaled in the chamber l5 of the
casing, and such casing is provided with an air
nozzle l6, so arranged within the chamber l5 as
to cause a jet of air to impinge on the blades ll
of the rotor. The outlet port I8 of the chamber 35
is connected by a passage l9 to the source of
low pressure such as the intake manifold of the
' internal combustion engine, not shown.
Fig. 3 is a similar view through the rotor cham
40 her of the turbine.
quently, practically all the air admitted to the
carburetor will be caused to travel through the
cleaner cylinder. The lower arcual portion of
'
'
The air ?lter may be of any approved type
having parts movable for the purpose of ridding
the same from the collected dust. Preferably
the filter is equipped with a cleansing liquid bath,
45 as that embodiment herein illustrated.
Referring more particularly to the drawing,
the numeral 1 designates the air ?lter or screen
which is shown as being cylindrical in design
and closed at one end by a closed head 2 and at
50 its opposite end by a perforated or foraminous
head 3. The cylinder is provided with a hub 4
for rotational mounting upon the shaft 5 and
by which it is supported in a casing or housing 6.
The housing is provided at appropriate places
' 65 with air induction openings 1 through which air
The point of connection to the manifold is
preferably at the engine side of the throttle 40
wherein the suction in?uence is more pronounced
when the throttle valve is closed and less no
ticeable when the throttle is opened. ~Conse
quently, the discharge of air from the jet IE will
likewise be variable, varying more or less in its 45
intensity according to the suction in?uence at
its source. The rotor therefore will be driven- at
varying speeds, and when the throttle is in closed
position, and the engine idling, the higher de
gree of suction will increase the rotative speed 50
of the rotor and likewise the rotative speed of
the screening cylinder. This increase in the ro
tative speed of the screening cylinder, as it dips
into and passes through the washing bath, will
tend to cleanse more thoroughly the wet surfaces 55

of their gritty and dusty deposits and when the
throttle valve is next opened to increase the
speed of the engine a cleaner and greater surface
area will be presented to the increased air ?ow.
Consequently,
the
movement
of
the , screen
through the bath will be more or less intermit
tent, accelerating at intervals and thereby tend
ing to more thoroughly wash the screen of the
' adhering foreign particles.

The turbine may have its rotative speed re
duced through the reduction gearing 20 as its
power is transmitted to the hub 4 of the cylinder,
the same being detachably connected to the hub
by interengaging clutch parts 2| on the oppos
ing ends of the hub and the driven shaft 22. The
shaft 22 is illustrated as being journaled in a
bearing 24 and may be provided with an axial
ing member for so moving the same through the
bath, a suction passage from the motor to the
intake manifold, and an air inlet leading into
the motor from the down stream side of the
screening member, whereby the air drawn
through the motor for actuating the same will
be cleaned before entering the manifold.
2. An air cleaner for internal combustion en
gines, comprising, in combination with the intake
manifold of the internal combustion engine and 10
the air intake of its carburetor, a movable air
screening member, a liquid bath through which
the screening member is slowly‘moved, a housing
for the screening member provided with air in
flow means at the up stream side of the screen 15
ing member and an outlet chamber at the down
stream side of the screening member, means for
bore 25 to receive the adjacent end of the shaft ' connecting the chamber to the air intake of the
5 for giving support thereto.
The jet I6 is con
20 nected by passage 26 to the chamber 8 so that
clean air will be used in driving the rotor. ‘This
will insure the entire air supply to the intake
manifold being screened. The speed of the tur
bine may be determined by the valve 21. The
motor drive is readily attachable and detachable
from the housing 6 so as to facilitate repair and
replacement of the several parts. The screening
cylinder is renderedaccessible by removal of the
30
closure 6’.
The operation of the cleaner unit, according
to the present disclosure, depends on the opera
tion of the internal combustion engine and will
operate only when, through the engine operation,
there is low pressure influences in the intake
manifold. A portion of the puri?ed air, being
removed through the passage 24, is carried over
into the turbine to drive the same, such air ?ow
being induced through the passage Hi to the in
take manifold at a point where the suction in
40 i'luence is more pronounced, thus setting up the
required pressure differential to cause such air
flow. As the engine is continuously operating
the screening cylinder is slowly’ revolving so as
to present freshly washed surface areas to the in
' ?owing air and to remove the dust laden surfaces
to the bath. Incidental to the operation of the
engine, the movement of the dust laden surfaces
through the washing liquid will be variable and
irregular and thereby result in a more eilicient
50 washing action due to such agitative action.
What is claimed is:
1. An air cleaner for internal combustion en
gines, comprising, in combination with the in
take manifold of the internal combustion engine
55 and the air intake of its carburetor, a movable
air screening member, a liquid bath through
which the screening member is moved for wet
ting surface portions thereof, means for direct
ing an air flow over the exposed wet surface por
60 tions of the screening member, a suction oper
ated motor operatively connected to the screen
carburetor, a suction operated motor operatively
connected to the screening member for driving 20
the latter continuously, said motor having an air
inlet opening communicating with such cham
ber and an air outlet member communicating
with the intake manifold, whereby the variable
suction influences in the latter will accelerate the
motor at intervals and effect an irregular move
ment of the screening member through the bath.
3. An air cleaner for internal combustion en
gines, comprising, in combination with the in
take manifold of the internal combustion engine
and the air intake of its carburetor, a movable
air screening member, a liquid bath through
which the screening member is agitated, a hous
ing for the screening member provided with air
in?ow means at the up stream side of the screen
ing member and an outlet chamber at the down
stream side thereof, means for connecting the
chamber to the air intake of the carburetor, and
asuction operated motor having an‘ air inlet
opening communicating with such chamber and
an air outlet member communicating with the
intake manifold, said motor being detachably
mounted on the housing and having its air inlet
communication established and broken upon the
mounting and demounting of the motor.
4. An air cleaner for internal combustion en
gines comprising an air screening member, a
housing for the member provided with air in?ow .
and air out?ow chambers, said screening mem
ber being interposed between said chambers to
screen the air flowing therebetween, a washing
bath for the screening member, means for mov-'
ing portions of the screening member into and
out of the bath, and an-air operated motor hav
ing air in?ow communication with the outlet
chamber and an out?ow passage adapted for
connection to the intake manifold of the engine
whereby screened air is by-passed through the
motor into the manifold for actuating the motor.
