3 Claims.
My new invention pertains to the ventilation
(o1. 9s-94)
cylinder H,
'
The shaft ‘of the motor is hori
of inhabited quarters and to the circulation of ‘ zontally disposed and in such position that the
air within such quarters.
An object of my invention is to provide a fan
5 assembly which may be mounted in a window of
any room and may be utilized either to circulate
air within the room or to induce air to enter the
room from the outside atmosphere and at the
same time to deliver such outside air into the
10 room at fairly high velocity, thus causing circu
lation of air within the room.
My new invention will be understood from the
following speci?cation taken in connection with
the attached drawing in which:
Figure 1 illustrates a vertical cross-section
taken through the center of the fan assembly.
Figure 2v illustrates a vertical cross-section in
the plane 2-_-2 of Figure 1.
Figure 3 illustrates a vertical crossésection in
20 the plane 3—3 of Figure 1.
Figure 4 illustrates a vertical cross-section in
the plane 4—& of Figure 1.
Referring to the drawing, the numeral 8 indi
cates a plate, vertically disposed, which may be
25 made of wood or metal or other suitable mate
rial and which is shown disposed in a window,
the lower portion of the plate 8 being supported
on the window sill 9. The window sash I 8 is
shown supported by and in contact with the
3 O upper edge of plate 8. All of that part of the ap
paratus to the right of the plate 8 is located
within a room, while all of that part of the appa
ratus shown to the left of the plate 8 is located
in the outside atmosphere. A circular opening
35 I I is cut through plate 8. Supporting rods i2
penetrate plate 8 and are disposed vertically with
respect to the plane of plate 8 and are attached
to plate 8 and extended horizontally in both di
rections from plate 8. To the extremity of the
40 portions of supporting rods I2 which extend into
the outside atmosphere is attached a vertically
disposed circular plate l3 the plane of which is
parallel to the plane of plate 8. A horizontally
disposed cylinder M, the diameter of which is
45 less than the diameter of plate I 3 and the out
side diameter of which is approximately the di
ameter of the opening II, is maintained in posi
tion by guides i5 and i6 which are rigidly at
tached to cylinder M and are free to move along
50 supporting bars l2. A cylinder H is horizontally
disposed and rigidly attached to supporting bars
l2 by means of brackets iii. A motor l9, to the
shaft of which is attached a propeller type fan
2!], is supported by supporting brackets 2| which
55 are rigidly attached to both the motor and the
fan 20 may be mounted within the cylinder l1.
De?ector plates 22 are shown attached to ‘cylin
der ll‘. These de?ector plates are arranged ver- 5
tically, their planes being perpendicular to the
horizontal and they are so attached to the cylin
der I‘! that the position of the plane of each of
them may be independently changed with respect
to the plane of plate 8.
1O
The motor i9 is reversible and is provided with
a suitable switch, not shown, by which the motor
may be rotated in either direction.
'
l
The cylinder l4 may remain in the position
shown in solid lines or may be moved to the posi
15
tion shown in dotted lines or to any intermediate
position. When the cylinder I4 is in the position
shown in solid lines, the fan may be operated to
deliver airin either directionthrough the cylin
der [1 and will thus cause rapid circulation of ‘20
the air within the room in which the fan is lo
cated. When the cylinder l4 has been placed in
the position shown in dotted lines the fan may
be operated to deliver air from the room in which
it is- located through cylinders I1, and M to the
outside atmosphere but in such case will prefer
ably be used to deliver air from the outside at
mosphere into the room, thus not only ventilating
the room but at the same time causing circulation
of air within the room.
30
Normally during the daytime the cylinder M
will be maintained in the position shown in solid
lines and the fan will be operated to circulate
the atmosphere within the room during the day
time at which time the air within the room would 35
normally be cooler than the outside atmosphere.
After the sun has gone down and the temperature
of the outside atmosphere has dropped to a
temperature below that of the atmosphere within
the room, the cylinder M will preferably be moved
into the position shown in dotted lines and the
fan will be operated to deliver air from the out
side atmosphere through the cylinders II and I7
and thence through de?ectors 22 into the room,
thus e?ecting both the cooling of the room and 45
the agitation of the atmosphere of the room. 7
It should be noted ‘that when the cylinder i4
is in the position shown by dotted lines this cyl
inder, together with the cylinder ll, form a con
tinuous free open passageway through which air 50
may be delivered either from the room to the
outside atmosphere or from the outside atmos~ ’
phere to the room and that when the cylinder
I4 is moved into the position shown in solid lines
the effect is to close this passageway to the out- 55
2',

side atmosphere and to openrthis passageway to
, the atmosphere of the room, thus permitting
circulation of the atmosphere of the room.
‘In accordance With the above'it is apparent
that my new invention provides a fan assembly
