This invention‘ relates to air-conditioning de
vices. It is particularly directed to a window
ventilator, and the like articles.
An object of this invention is to provide a
5‘- window ventilator of the character described,
having means to eliminate dust from air entering
the room, while yet permitting a free flow of air
.
therethrough.
'
'
‘
Still another object of this invention is to pro
vide a neat, compact and durable window venti
later of the character described, which shall be
relatively inexpensive to manufacture, easy to
zap-install and. clean, and withal, practical and effl
cient to a high degree in use.
Other objects of this invention will in part be
obvious and in part hereinafter pointed out.
The invention accordingly consists in the fea
25 vtures of construction, combinations of elements,
and arrangement of parts which will be exem
pli?ed in the construction hereinafter described,
and of which the scope of application will be indi
cated in the following claims.
In the accompanying drawing, in which is
shown one of the various possible illustrative em
bodiments of this invention,
Fig. 1 is an outside elevational view of a win
dow frame provided with an air-conditioning
35: window ventilator embodying the invention;
Fig. 2 is a cross-sectional view taken on line
2--2 of Fig. 1;
.
Fig. 3 is a partial elevational inside view of the
ventilator with parts broken away to show the
40- interior construction; and
Fig. 4 is an elevational cross-sectional view of
a portion of the window frame and windows slid
ably mounted therein, and illustrating a device
forming part of my invention for preventing air
45 from ?owing between the windows.
Referring now in detail to the drawing, Ill
designates a window frame of usual construction
and I I designates a window slidable therein. The
_
and provided with a downwardly extending .,
?ange 23. The front wall 20 has, adjacent the
top thereof, a plurality of spaced openings or
'
A further object of this invention is to pro
l011vide a ventilator of the character described,
which may be readily mounted in position on a
window frame‘and in which water is employed to
remove dust from the air entering the room and
to add moisture to the air for conditioning the
lat-same.
bottom wall is a rear vertical wall 2 I. The rear
wall 2| extends to a higher level than the wall
20 and terminates in a top edge 2 Ia. Extending
rearwardly from the top‘ of the front wall 20 is
a top wall 22, terminating short of the wall 2!
frame I0 comprises a bottom portion I3 and side
50. portions I4. Mounted within the frame Ill and
below the window II is an air-conditioning win
dow ventilator I5 embodying the invention.
The ventilator I5 may be made of wood, gal
vanized iron or other suitable sheet metal. The
55- 'same comprises a case I6 and a removable cover
I1 for said case. The case I6 hasa ?at bottom
wall I9 adapted to rest on the bottom of the
frame I3. Extending upwardly from the front of
the bottom wall I9 is a vertical front wall 20;
60 and extending upwardly from the rear of said
perforations 25 for the purposes hereinafter ap
pearing. The rear wall 2| has, adjacent the top
thereof, a plurality of spaced openings or perfo
rations 26, the purpose of which will be explained
hereinafter. Said front wall'is also provided at
a bottom corner thereof with a removable screw
plug 27 for draining water within the case I6, as
will appear hereinafter.
The case 16 further comprises end walls 29' to
close the ends of the case.
The end walls 29 in
terconnect the top wall 22 with the bottom wall
I9 and each has a front vertical edge 30 extend 20
ing above the top wall 22 and a top horizontal
edge 3| somewhat below the level of the top edge
Zia.
The cover I‘! has a top wall 35 contacting the
edges 3| of the end walls 29 and a folded-over 25
channel 36 adapted-to frictionally engage the
upper edge Zla of the rear wall 2|. Extending
downwardly from the wall 35 is a vertical wall
38 contacting the edges 3!] and projecting into
the case I6. The lower end of the wall 38 pro 30
jects below the ?ange 23 and serves as a baffle
for air entering the openings 26 and passing
through the case to the openings 25.
The por
tion of the wall 38 which extends below the top.
wall 22 of the case I6, is preferably somewhat 35:
narrowed to permit insertion thereof into the
case.
As shown in Fig. 2 of the drawing, the bottom
of the window I4 contacts the wall 35 of the cover
I‘I, so that air entering the room must pass 40
through the ventilator. Water may be placed into
the case I6, the level of the water being below
the bottom edge of the wall 38 of the cover [1.
It will now be understood that air entering the
room must ?rst pass through the openings 26 45
beneath the baffle 38 and through the openings
25 as indicated by the arrows in Fig. 2 of the
drawing. The air while passing through the
ventilator is cooled and'cleaned of dust by the
water and gathers moisture to condition the air. 50
The water may be removed from the ventilator
by unscrewing theplug 2'I.
,
It will be noted that the front window II is
moved down into contact with the top of the
ventilator I5 as shown in Fig. 2 of the drawing. 55
Means is also provided to prevent air from ?ow
ing between the front and rear windows and thus
entering the room, whereby air can only enter
the room through the ventilator. When the front
window is in contact with the top of the venti

lator I5, the rear window I la is raised. The bot
tom portion III) of the window IIa is below the
top portion of the front window I I. As shown in
Fig. 4 of the drawing, there is attached to the
5 bottom of the window III), a rubber strip 40, the
front edge of which contacts the pane I I0 of the
window II, and hence prevents air from passing
wall, the upper edge of said rear wall being at a
higher level than the top of said front wall, a
top wall extending rearwardly from the top end
of said front wall and terminating short of said
rear wall, a downwardly extending ?ange on the
rear end of said top wall,‘said case being provided
with end walls, said end walls interconnecting
between the windows. Any air entering the room ; the top wall with the bottom wall and each hav
through the frame I0 must therefore pass through ing a horizontal edge somewhat below the top

edge of therear wall and a vertical edge extend 10
It will thus be seen that there is provided a ing above said top wall, and a cover for said
device in which the several objects of this inven
case comprising a channel-shaped portion fric
, tion are achieved, and which is well adapted to
tionally receiving the top edge of said rear wall,
meet the conditions of practical use.

As various possible embodiments might be made
of the above invention, and as various changes
might be made ,in the embodiment above set
forth, it is to be understood thatall matter here
in set forth or shown in the accompanying. draw
20ising
is to be interpreted as illustrative and not
in a. limiting sense.
