(C1.` 13s-_5.2)
For a. clear understanding of an exemplary use
for the invention described herein, reference is
made to my co-pending applications Ser. No.
may frequently be desirable particularly if the
temperature of the conditioned air Within the
canopy tends to become too low.
My present invention, as addressed to the struc
714,687, filed March 8, 1934; Ser. No. 715,077, tures to which I have referred', pertains to the 5
filed March 12, 1934; and Ser. No. 716,488, filed , canopy construction and- to the supportingmeans
March 20, 1934. In the saidv co-pending cases I therefor. The general objects of my invention
have described a device for cooling and condition
ing air in a restricted space for immediate oc
cupancy whereby the comfort. and health of the
user may be served without the provision of com
plicated' and costly apparatus and the utilization
of great amounts of power. In-the exemplary
embodiments of my device therein described I
have` shown the combination of a canopy over a
l Ol
bed to define an area of immediate personal oc
cupancy together with electrical and mechanical
means for conditioning and cooling the air with
in the said canopy. In these embodiments the
electrical and mechanical equipment or at least
the greater part of it is contained in an orna
mental cabinet, stand'or housing member adapt
ed to be placed alongside of a bed.
The cabinet
has an arm or arms extending upwardly and out
wardly over the bed, to which arm or arms ther
canopy is attached and by which it is supported.
The lower edges of the canopy are free and are
tucked in around the edges oi the bed e. g. around
the mattress. Thus a closed space is provided.
It has been found most convenient and effective
to provide a canopy of the general style of the
familiar A tent, in which, however, the ridge is
preferably of less length than the length oi the
lower part of the canopy, both for convenience in
supporting the device and also to restrict the
space to be cooled and conditioned to the mini

arrangement of parts whereby these objects are
attained. Reference is now made to the draw

At 3v I have shown the cabinet of one of my air

described in detail since reference to my co

my present invention. Briefly sta-ted; the cabinet
3 will contain a complete refrigerating mecha

in a compartment sealed from a compartment in
If the walls of such canopies, however, are which the low pressure or evaporator side is lo-j

arms 1 and 8 by the engagement of the hooks

of course, that any manner of engagement of the

canopy frame fall within the scope of my inven
as shown, so that the ends of these arms are
comparatively widely interspaced and lie sub

to these arms that the canopy 9 is hung.
It is
I have indicated hereinabovethat the canopy 9
is preferably in theshape of a tent having sloping
side and end walls; but as aforesaid, it is desir
10 able to keep the side walls distended so that in
stead of falling from the ridge to the edges of the
bed in substantially a single plane, they fall out
Reference to Figs, 1 and 2 may be made for
the construction of an access and control ar
rangement which I employ in connection with my
canopy. A side of my’canopy is provided with a
triangular opening indicated at 25. The edges of
this opening may be reinforced if desired by frame
wardly at a greater angle for a substantial dis
tance and then fall downwardly to meet the
members in a way which will readily be under
edges of the bed in as nearly a vertical plane as is
stood by one skilled in the art although ordinarily
I have not found this necessary or advisable. I 15
have found it preferable so to locate the tri
angular opening that the base of the triangle is
practicable. It will be clear, of course, that beds
vary in size and shape and it is not ordinarily
necessary with my construction to provide vary
ing types of canopy for varying sizes of bed. Con
20 sequently, the “planes” to which I have referred
upwardly disposed. Adjacent the downwardly ex
tending sides of the triangle I sew triangular
shaped flaps 26 and 21 which are adapted to be
above are approximate in nature.
As a framework for my canopy I prefer to pro
vide the means illustrated in Figs. 3 and 4. Here '
I have shown end fittings which may be made
of cast metal and which have a leg I0 adapted
to be horizontally disposed and two other legs
I I and I2 at the end of the leg I0, disposed at
angles of substantially 90 degrees thereto but
preferably disposed as respects each other at an
These legs are
perforated for the reception of arms providing
frame members for the canopy and the perfora
tions may be threaded or not as desired.
The end members also have an upstanding leg
35 I3 at the other end of the leg I0. , This leg I3 is
also perforated and is adapted to receive a hook
member I4 by which the canopy frame may be
30 angle of less than 180 degrees.
hung to the ends of the arms 1 and 8 which are
perforated for the purpose shown.
A ridge for the tent may be formed by a single
rod entering the perforations in the'leg I0 of two
of the end fitting members; but I prefer to make
the ridge of my canopy adjustable and tothis end
I have shown the ridge in Fig. 3 formed of a pair
of rods I5 and I6 each attached to a leg I6 of
one of the end fittings, and fastened together in
such a way as to be longitudinally adjustable.
One such way is illustrated in Fig. 3 as compris
ing a sleeve I'I through which both of the rods I5
50 and I6 pass and which grips these rods fric
tionally, so that while longitudinal adjustment
may be made the rods will be adequately held in
adjusted position.>
The legs II and I2 of the end fittings receive
55 in their perforations side rods I8 and I9, 20 and
2|. The ends of these rods may be curled as at
22 or rounded or otherwise provided with means
minimizing wear on the canopy. The various
rods may likewise be of resilient metal. It is not
60 necessary and in some cases it is not particularly
material but it is of advantage in many instances
so to form the rods I8 and 2I. This gives to the
canopy a measure of self adjustment to meet
varying conditions.
The manner of use of the frame structure in
cooperation with the arms ‘I and 8, and the con
ditioning apparatus 3 by which they are support
ed, will be clear from an examination of Fig. 1.
70 Two rods I5 and I6 form a ridge pole for sup
porting the vridge of the canopy throughout its
length. "I’he armsV I8, I9, 20 and 2| distend the
sides of the canopy so that there is an angular
displacement between more or less planar por
75 tions marked 23 and 24 of each side wall. Both
disposed either to cover or to uncover the open
ing in the canopy. To this end the unattached
corner of each flap is provided with some fasten
ing means, either a buttonhole 28 as shown, or a
button, or one of the parts of a separable fastener.
Corresponding fastening portions 29 and 30 are
located on the Wall of the canopy adjacent an
edge of the perforation 25 therein, so that the
flaps may be held in closed position as illustrated
in Fig. 1. Other cooperating fastener portions 3|
and 32 may be located on the wall of the canopy
so that the flaps may be fastened in opened posi
tion. 'I'he flap 26 is shown fastened in opened po
sition in Fig. 2.
I have found it necessary to provide but one
such access opening in my canopy although more
may be provided, if desired, in the same or in
different wall portions. This opening not only
provides ready access to the canopy without
disturbing the relationship of the canopy to the
both of the flaps may be left open during the use
of the structure. It will be noted that prefer
ably the opening is disposed considerably above
the level of the top of the mattress and also that
the lowermost part of the opening has the least
effective area. Thus, since cooled air is relatively
heavier than warm air one or both of the flaps
may be left open for greater air infiltration While 50
maintaining a body of cooled air adjacent the
mattress and the coverings thereon. In this
way the effect of conditioned air may be ob
tained without the full lowering of temperature
within the cabinet of which the apparatus is
capable under any given conditions.
Again one or both of the flaps 26 or 21 may be
made of a material differing from the material
of the canopy as by being more Apermeable to air.
One or both ofthe flaps may thus be made of 60
netting. Again it is possible to provide a plu
rality of flaps in place of each of the flaps 26
and 27. Thus each pair of. flaps may comprise
one of netting and one of heavier material com
parable to the material of the canopy, or more or
less air pervious. One such supplementary flap
has been shown in Fig. 2 at 26a.
Modifications may be made in my invention
without departing from the spirit thereof.
Having thus described my invention,` what I 70
claim as new and desire to secure by Letters
Patent, isz-
