Patented May 5, 1953 UNITED STATES iATENT OFFICE Claims.

As is well known in the air conditioning art,

there are many persons who would like to have the interior of their house or office comfortably cool during the summer months, but who dislike having cooled air blown directly into the rooms.

It is an object of the present invention, therefore, to provide a cooling system for cooling the interiors of dwellings without forcing cooled air directly into said interiors.

Another object is to provide a cooling system which cools the exterior surfaces of the dwelling.

Another object is to provide a cooling system which is particularly applicable to stucco type dwellings.

Another object is to provide a cooling system which can be easily installed in either existing structures or new structures.

Other objects are to provide a cooling system which is relatively inexpensive to install and operate, which is simple in construction, and which will operate for long periods of time with a minimum amount of replacement and repair.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing wherein a preferred embodiment of the present invention is shown, in which:

Fig. 1 is a front elevational view of a house provided with a cooling system embodying the teachings of the present invention.

Fig. 2 is a side elevational view of a house taken from the right of Fig. 1; and

Fig. 3 is an enlarged vertical sectional view of one of the outlet vents taken on the line 3--3 of Fig. 2.

Referring to the drawing more particularly by reference numerals, It indicates a stucco type house containing a cooling system constructed in accordance with the teachings of the present invention.

The house ll] includes a roof [2, a first front wall 14 which contains a window it, a second front wall It which contains a door 26 and a double window 22, and a side wall 24 which contains three windows 26.

An evaporative type air cooler 28 containing a 2 blower is supported on the rear portion of the roof I? by a rack 30. An air duct 32 leads from the air cooler 28 through the roof [2 and into the attic of the house 10.

Outlet vents 34 of the configuration shown in Fig. 3 are contained in the upper portions of the walls i4, i8 and 24 directly above windows and doors. As shown in Fig. 1, there are also two vents 34 in the first front wall l4 on both sides of the window 16.

Each of the outlet vents 34 (Fig. 3) includes a sleeve 36 containing a flange 3'! at the inner end thereof, which extends through the wall above the ceiling joists and into the attic of the house Iii. In new houses, the sleeve 36 is installed when the wall is built, and, in old houses, a hole is cut in the wall and the sleeve 36 is sealed in place with stucco type putty.

An elbow 38 having a horizontal portion 40 and a vertical portion 42 is disposed with the end of the horizontal portion 40 within the outer end of the sleeve 36. Screws 44 removably fasten the two members together.

Pivotally mounted at the lower end of the vertical portion 42 is a cover 46 for closing the vent during the winter months. The cover 46 contains a projection 48 for engagement with a spring detent 50 fastened adjacent the lower end of the vertical portion 42.

As indicated in Fig. 3, the length of the vertical portion 42 can be varied to bring the lower end as close to the top of the windows or door as desirable, and, manifestly, the width can also be varied.

Operation During the summer when it is desirable to have the interior of the house cooler than the atmosphere surrounding it, the covers 46 of the outlet vents 34 are opened and the air cooler 28 is placed in operation.

The warm air is drawn into the cooler 28, cooled, and then forced through the air duct 32 and into the attic of the house I 0.

The cooled air in the attic, which is under a slight pressure, is then forced out of the attic ducts 34 and down over the windows, doors and walls of the house, thereby cooling it.

If one side of the house is in the shade, the covers 46 on the outlet vents 34 on that side can be closed so as to increase the flow of cool air over the other portions of the house which are at. a higher temperature.

Also, some of the cooled air which passes over the openings, such as the door and windows, en-

ters into the rooms of the house through said openings with the same effect as a natural cooling breeze.

Thus, it is apparent that there has been provided a cooling system which fulfills all of the objects and advantages sought therefor.

It is to be understood that the foregoing description and the accompanying drawing have been given only by way of illustration and example, and that changes and alterations in the present disclosure, which will be readily apparent to one skilled in the art, are contemplated as within the scope of the present invention which is limited only by the claims which follow.

What is claimed is:

l. A cooling system for use with a dwelling having an attic, comprising an air cooler; means for conducting the air from said cooler into the attic of the dwelling; and means for directing the cooled air from said attic over the outer surfaces of the dwelling, said last-named means including at least one duct having its inner end opening into the attic and its outer end containing an opening for directing the air in a downward direction.

2. A cooling system for use with a dwelling having an attic, comprising an air cooler; means for conducting the air from said cooler into the attic of the dwelling; a series of outlet ducts having their inner ends opening into the attic and their outer ends containing openings for (ii-- recting the air from the attic in a downward direction; and means for closing off said outlet ducts.

3. A cooling system for use with a dwelling having an attic, comprising an air cooler; means for conducting the air from said cooler into the attic of the dwelling; and at least one outlet duct for directing the air from the attic over the outer surfaces of the dwelling including a sleeve-like member extending through a wall of the dwelling above the ceiling joists, and an elbow-like member fastened to the outer end of the sleeve-like member.

4. A cooling system for use with a dwelling having an attic, comprising an air cooler; means for conducting the air from said cooler into the attic of the dwelling; and a series of outlet ducts for directing the air from the attic over the outer surfaces of the dwelling, each of said ducts including a sleeve-like member extending through a Wall of the dwelling, an elbow-like member fastened to the outer end of the sleeve-like member so that its free end is directed downwardly, and a closure member pivotally mounted adjacent the lower end of the elbow-like member for closing the duct.

5. A cooling system for use with a dwelling having an attic, comprising an evaporative-type air cooler mounted outside of the dwelling; duct means between the cooler and the attic of the dwelling; and a series of outlet ducts having their inner ends opening into the attic and their outer ends disposed down ardly.
