Application November 16, 1948, Serial No. 60,233
This invention relates to new and useful improvements in air coolers and the primary object of the present invention is to provide a'simple and practical air cooling unit for buildings, vehicles and the like.
Another important object of the present invention is to provide an air cooler including a supply conduit having an outlet opening through which moisture laden air is delivered and embodying novel and improved means for introducing moisture or liquid into the conduit and into the path of air directed into the conduit by a fan.
A further object of the present invention is to provide an air cooler that is quickly and readily applied to or removed from the conventional window structure of a vehicle without in any way harmfully efiecting such a window structure.
A still further aim of the present invention is to provide an air cooler that is small and compact in structure, neat and attractive in appearance, strong and reliable in use, light and convenient to handle, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.
Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure l is a fragmentary perspective view of a vehicle and showing the present invention applied to the same;
Figure 2 is a perspective view of the present invention;
Figure 3 is a longitudinal vertical sectional view taken substantially on the plane of section line 3-3 of Figure 2;
Figure 4 is a transverse vertical sectional view taken substantially on the plane of section line 4-4 of Figure 1;
Figure 5 is a transverse vertical sectional view taken substantially on the plane of section line 55 of Figure 3; and
Figure 6 is a rear elevational view of the present invention.
Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral l0 represents an elongated hollow casing generally, including an upper arouate section 52 and a lower arcuate section [4 which are provided with flat inner walls l6 and I8 that are co-planar or flush.
The sections 12 and M are closed at their rear 7 Claims. (Cl. 261-92) ends by walls 26 and 22, and the lower section M is also closed at its forward end by a wall 24 whereas the upper section I2 is open at its forward end to provide an inlet opening.
The bottom section M is provided with an upper wall 26 and forms a reservoir or tank that receives a supply of liquid or fluid, such as water 30' which is placed into the lower section through an inlet nipple 39 at the,,rear wall 22. This nippie 3% is normally closed by a closure cap 32 that is frictionally fitted on the nipple or threaded on the nipple.
Journaled for rotation in bearings 34 mounted on the upper wall 26 of the lower section [4, is a shaft 35 one end of which projects outwardly from the open end of the section 12 to support a fan blade 38 that will draw air into the upper section through the open end thereof as the said fan blade rotates.
The inner end of the shaft 35 supports a pair of diametrically opposed, oppositely arranged angle members or radial blades 40 that rotate in both of the sections l2 and It and through an opening 42 provided in the upper wall 26 in order to supply the liquid 30 from the lower section l4 into the upper section [2.
Suitably secured to the inner fiat wall I 6 of the upper section I 2, is an elongated, substantially rectangular anchoring strip 44 having an opening 46 adjacent one end that registers with an outlet opening 48 provided in the inner wall 16 of the upper section, adjacent the rear wall 20 thereof.
A substantiall U-shaped channeled guide 50 is fixed to the strip .4, adjacent the upper, lower and rear edges of the opening 46 and slidably receives the longitudinal edges of a substantially rectangular closure or valve 52, having a finger gripping portion 54, for regulating the passage of moisture laden air from the upper section I2.
Suitably fixed within the upper section 12, between the open end of the section 42 and the outlet opening 48, is a suitable filter unit that will prevent dust and the like from passing outwardly through the opening 48 and which will also restrict the amount of moisture laden air passing through the filter toward the outlet opening 43.
A flexible, water absorbent material 58 is mounted in the upper section l2 between the filter 5-5 and the open end of the upper section and bears against the inner periphery of the upper section and the filter 56. This material 58 is retained in the upper sectionby a screen mounting or matting 60 that is suitably secured to the upper section.
The forward ends of the sections 12 and [4 are provided with outwardly flared, arcuate flanges 62 and 64 respectively to further aid in directing air into the upper section.
The rear wall of the upper section [2 is provided with an opening 66 and a U-shaped channeled guide 68 is fixed to the rear wall 20 and slidably receives a closure 10 for controlling the opening 66.
In order to permit the instant air cooler to be applied to a vehicle 12, there is provided an arcuate or channel-shaped holding strip 74 that is fixed to the strip 44 and which embraces and bears against the inner surface 18 of the window structure l8 (see figure 4).
The upper edge of the strip 44 is received in the window channel Bi), and the lower edge of the strip 44 bears upon the upper edge of the Window 82.
A further anchor strip 84 depends from the strip 44 and bears against the inner face of the window 82 to prevent the casing I9 from falling outwardly from the window and the flat walls [6 and [8 of the sections l2 and M bear against the outer surface of the window.
In practical use of the present invention, the closure 52 is moved to an open position and the closure H! is moved to a closed position. As the wind enters the upper section and engages the fan blade 38 to rotate the same, the blades 40 will be rotated to disperse the liquid into the upper section.
As the air agitated in the upper section and presses through the filter 58, the same will then pass outwardly from the opening 48 and into the room area or vehicle.
Obviously, by manipulating the closures 52 and 10 a controlled supply of air into the vehicle or 1 room area may be maintained and rain water can be restricted from entering the opening 48.
Although the fan balde 38 and blades are rotated by air entering the casing for the purpose of simplicity, any suitable motor means could be utilized for driving the same.
In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description i accordingly deemed unnecessary.
