Application February 18, 1938, Serial No. 191,325

1 Claim.

This invention relates to air conditioning means, the general object of the invention being to provide inexpensive means for washing and cooling the air in a building by forcing air through a casing by a fan and causing the air passing through the casing to operate water lifting means, which causes the airto pass through the water so, thatthe airis washed and cooled, the invention eliminating pumps and other expensive means for spraying the water through the air.

The invention also consists in certain other features of construction, combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claim.

In describing the invention in detail reference will be had to the accompanying drawing wherein like characters denote'like or corresponding parts throughout the several views and in which:

Fig. 1 is a longitudinal sectional view through one form of the invention.

Fig. 2 is a'view looking towards the fan end of the device.

Fig. 3 is a view looking towards the other end thereof.

Referring to Figs. 1, 2 and 3, the numeral I indicates an elongated casing supported in any suitable manner, such as by the legs 2. A motor 3 is centrally supported in the casing, adjacent one end thereof, by the means I and the blades of a fan 5 are attached to the shaft of the motor. A screen 6, preferably covers this end of the casing. A longitudinally extending shaft 1 is centrally supported in the casing, by the cross bars 8, the shaft extending from the motor to the other end of the casing. The shaft has attached thereto the disk 9, the major part of which is composed preferably of fabricated cloth or porous canvas, as shown at I ll. The shaft also has attached thereto a disk ll provided with the inclined blades l2 and this disk also has its major portion composed of porous material as shown at E3. This disk II is spaced from the first disk and is located adjacent the end of the casing remote from the fan. Partitions l4 extend upwardly from the bottom of the casing and form a water chamber, into which extend the two disks, so that the porous material of the two disks will be saturated by the water as the disks pass through the chamber.

Thus it will be seen that as-the fan rotates it will draw air through the casing and this air acting against the blades l2 will cause the disk I l to rotate and as said disk is attached to the shaft,

said shaft and the other disk} will be rotated and as the porous material carried by the disks passes through the water, such material will be saturated with the water and thus the air passing through the material will be washed and cooled 5 by the water in the material and by the water running down the material, as it is lifted thereby.

If desired, the blades may be shortened so they will not extend into thewater and furthermore the fan can be made to push the air through 10 the casing, instead of pulling it through the casing, as shown in the drawing.

Thus it will be seen that the invention provides an inexpensive air conditioning means which eliminates pumps and the like as the air forced 15 disposed cylindrical casing partially-open at its 30 inlet end and fully open at its exit end, a water chamber in the lower portion of the casing terminating short of the exit end thereoffcross bars secured within the casing transversely over the ends of the water chamber, a rotatable shaft 35 mounted in the cross bars axiallyof the casing, open frames secured to the shaft adjacent its ends and extending into the water chamber, porous material carried by said open frames for taking up water from the water chamber during rota- 40 tion thereof, radially disposed inclined blades secured to the inlet side of one of the frames adapted to extend into the water chamber and to be rotated by incursion of air into the casing, a motor in the casing beyond the water chamber 45 and in axial alignment with the shaft, brackets supporting the motor from the casing, and a fan of approximately the interior diameter of the casing mounted on the outer end of the motor shaft with its blades extending beneath the level 50 of the water within the water chamber when traversing the lower portion of the casing.
