AIR COOLER.

Specification of Letters Patent.

Patented Aug. 1, 1922.

Application filed Novemberi', 1919. Serial No. 336,417. r

T 0 all whom it may concern:

Be it known that I, CHARLES WESLEY STONE, a citizen of the United States, residing at Tuscaloosa, in the countyof Tuscaloosa and State of Alabama, have invented certain new and useful Improvements in Air Coolers; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in air coolers which may be used in connection with a furnace of any conventional hot air type and one object of the inventionis to provide a device of the above stated-character which is so constructed that cool air may be fed into the distributing pipes, of the furnace and thus cool air delivered to the rooms thereby permitting the building to be cooled during hot weather;

Another object of the invention is to provide an improved type of, air cooling de vice so constructed that air may be drawn through a pipe coiled about a cylinder or casing and then passed through a pipe coiled within the casing and discharged in the casing adjacent one end thereof and drawn out through the opposite end, an arm monia pipe being coiled within the casing to provide the cooling medium.

Another object of the invention is to so construct this cooler that it will be compact and thus take up a comparatively small amount of space.

Another object of the invention is to so construct this attachment that it will be simple in construction and consist of comparatively few parts.

This invention is illustrated in the ac companying drawings wherein:

Figure 1 is a view in side elevation show ing the attachment in connection with a conventional type of air furnace.

Figure 2 i an enlarged side elevation of the air cooler.

Figure 3 is a view showing the casing and outer pipe in section and the inner pipe in elevation.

Figure 4 is a View similar to Figure 3 showing the ammonia pipe in section and the air pipe in elevation.

Figure 5 is a transverse sectional view through the cooler.

This cooler may be used in connection with a hot air furnace which is of a conventional construction and provided with I the usual air inlet pipe "11 and distributing pipes 12. A fan housing 13in which will be positioned a conventional electric fan,

is positioned intermediate-the length of the 'pipe'll so that air may be'drawn into the fan housing through the pipe 11 and forced from the fan housing into the hot air furnace 1O frOm which-it is discharged through the pipes 12 to the various rooms to be cooled p The cooler is positioned between the fan housing and the source of air supply and is provided with a casing 1 1 having an outletopening 15 in one end. An air pipe or conductor .l6.is coiled about the casing 14 from the lower end to the upper end and is then carried back upon itself and coiled aboutthe casing from the upper end to the lower end, the last coils beingpositioned between the first coils. carried to the bottom ofthe casing and con nectedwithj the inner pipe whichis coiled within the casing and first carried upwardly in a spiral path and then reversed and carried downwardly in a spiral path with its open end positioned adjacent the bottom of the casing. It will thus be seen that the air must first pass upwardly around the casing and then downwardly around the The pipe 16 is then casing before entering the casing and will then be carried upwardly and downwardly within the casing inthe pipe 17. Air will thus be passed from the pipe 17 into the lower end of the casing and must travel upwardly through the casing to the top thereof before passing through the outlet 15 into the pipe 11 through which it will pass to the fan housing. In order to cool the casing and the pipe through which the air passes there has been provided an ammonia compressing apparatus 18 of any well known construction. A pipe 19 extends from the apparatus 18 into the lower end portion of the casing and then is coiled upwardly through the casing adjacent the side walls of the casing and after reaching the top it is carried downwardly ina spiral path with its convolutions positioned and closed by the convolutions of the first coil. After reaching the bottom of the casing the pipe extends through the casing and com municates with the apparatus 18. It will thus be seen that ammonia is compressed and forced through the ammonia coils thus taking up the heat. By having the ammonia coils extending close to the walls of the casing the outer air pipes will be cooled as well as the inner air pipes. This will cause the air to be cooled by passing through the pipes and also when passing through the casing after leaving, the air pipe. Therefore when the air leaves the cooler and passes to the fan housing, it will. be cooled and then distributed to the various rooms of the building through the medium of the furnace.

What is claimed is: I p 1. An air cooler comprising a casing, an air pipe having its exhaust end located within the casing and its intake end located exteriorly of said casing, said pipe being bent to form a pair of coiled portions and one of said portions surrounding the exterior of the casing and the other coiled portion located within-the casing, a cool ing medium" for the casing, and means for dispenslng cooled air from said casing.

3. An air cooler comprising a casing having an outlet opening, an air pipe having its exhaust end located in the casing and its intake located exteriorly of said casing, said pipes having pairs of double coiled portions and one portion surrounding the exterior of the casing from one end to the other end of the latter; said other coiled portion located in the casing and extending from one end of the casing to the other end thereof, said exhaust end of the pipe being located at an opposite end of the casing from the outlet opening,'a cooling medium for the casing, and air dispensing means connected with the outlet opening.

- 4:. An air cooler comprising a casing,-an air pipe having its exhaust end located within the casing and its intake end located exteriorly of said casing, said pipe being bent to form a pairof coil'portions, and one of said coil portions surrounding the exterior of the casing, and the other coil portion 10'- catedwithin the casing, 'a'coiled cooling element located Within the casing, and a suction fan connected to one end of the casing for dispensing cooled air therefrom.

In testimony whereof I a-flix my signature in presence of two witnesses.
