This invention relates to means for heating,

At the present time the general public is be
coming aware of a need for means to condition
the air in buildings, particularly in dwellings,
so that the air will have a uniform humidity and
so that the temperature ofthe air may be con
10 trolled appropriately in hotl and cold weather.
Most of the devices contemplating these results

sides Ill and II as particularly shown in Fig. 2
of the drawings, and that these sides will be
connected at equal spaced intervals throughout
their horizontal length by transverse webs I2

or dwellings. It is the principal object of the
present invention to provide means for obtaining
the results previously described which is installed
as an inherent part of a dwelling when built, and
not only utilizes the usual heating structures for
raising the temperature of the air but provides
means whereby the walls, iioors, and ceilings of
of the drawings, extend substantially the heighth
of the wall and communicate at alternate ends
through transverse openings I4. It will there- 15

sponding to the desired temperature required of
the air which is within the room.
The present invention contemplates the pro
vision of a building structure of flreproof con
struction, said structure embodying means with
in the walls thereof to permit a cooling or heat
ing medium to flow therethrough, and being pro
vided with additional means for controlling the
temperature of the air which is delivered di
30 rectly to the room.
The invention is illustrated by way of ex
These passageways, as shown in Fig. 1

sinuous path of travel for air throughout the
length of the wall. This sinuous passageway is
utilized in the present instance to accommodate
heated air or cooled air, the temperature of 20

ture and will thus be radiated from the wall
surfaces within the room. In this manner a
certain degree of temperature will be imparted
to the air contained within the room, irrespec 25
tive of circulation. For heating purposes the
present invention contemplates the use of a
hot air furnace, such as generally indicated at
I5 in the drawings. This furnace has the usual
iirebox I6 and a circumscribing outer shell I'I 30

any suitable manner and may be lined with a
portion of a dwelling indicating schematically
35 an arrangement of the present invention.

Referring particularly to Fig. 1 of the draw

forced concrete and constructed by the general
method and means shown in my co-pending
application entitled Concrete form, Serial No.
