4 Claims.

This invention relates to a machine for conditioning air and includes a rotating cylinder having a moisture retaining medium, and a motor driven fan for pulling the air through said cylinder containing said medium.

Another object of the invention is to provide equipment for washing and cooling air that may be manufactured in sizes suitable for use in an automobile, in residences or in commercial es-. tablishments.

Other objects will appear throughout the speciflcation.

In the drawings:

Figure 1 is a front perspective view of a device embodying our invention.

Figure 2 is a transverse vertical section of the device shown in Figure 1.

Figure 3 is a rear view of the device shown in Figure 1. I

Figure 4 is a longitudinal vertical section transverse to that of Figure 2.

Figure 5 is a detailed view of the lower end of the water reservoir showing the valve forming part thereof.

Figure 6 is a fragmentary perspective view of part of the cylinder.

Figure 7 is a fragmentary plan of one end of the casing top.

Figure 8 is a modified form of the device to adapt it for use in an automobile.

In the drawings the numeral l indicates a casing preferably constructed of metal such as galvanized sheet metal having four sides and a bottom and top portion. The top portion is provided with trimming comprising sections of angle iron 2, which surrounds the top on three sides as shown The fourth side is provided with a sheet metal strip 3 having struck down portions that are welded to the side shown'at the left in Figure 2.

The front portion 4 of the casing is provided with a circular opening 5 within which may be seen the fan 6 and motor 1 for driving the same. As shown in Figures 2 and 4 the motor is supported by a pair of upper and lower brackets l and II which brackets are each provided with a pair of legs l2 and 13' respectively. At the juncture of each leg with its bracket there is a slot l4, through which is threaded a metal band l having ears l6 through which a bolt l1 may .be passed, which latter has a nut l8 threaded thereon,- to thereby tighten the band. The extremities of each of the legs may be welded to four cross pieces of L cross-section mounted on the sides of the casing.

water reservoir 22. The upper end of the water reservoir is held removably in place by the U- shaped frame-work 23, the ends of which are provided with hinges 24, which are mounted on the angle iron trimming sections 2. When the framework is swung up to a vertical or near-vertical position the water reservoir may be removed and refilled. The reservoir has a U-shaped strap 26 which slidably houses the stem 21 of the valve 28. A bridge member 29 connects the legs of the U-shaped strap and provides an abutment for one end of the spring 30 which surrounds. the stem 21 and has its opposite end in abutting relation with the nut or washer 3| mounted on the stem 21, so as to force the valve 28 downwardly and thus close the valve 28 against the bottom 32 of the reservoir 22.

The reservoir is provided with an opening 33 (Figure 5), which is ordinarily closed by the valve 28. The end 34 of the stem 21 bears against the bottom of the casing when the reservoir is in position and thus unseats the valve permitting water to flow out of the reservoir into the space there beneath. This space is formed by the supplemental reservoir 35, the walls of which are composed of the extension 20, the pan end 28 and the partition wall 36. reservoir is formed into a plurality of water compartments by the partition 35, and these compartments communicate with each other by means of one or more apertures 31 which permits water to slowly pass from one compartment to the other. The right hand compartment forms a pan I9 previously referred to.

The lower portionof the cylinder 38 dips into the water located in the water compartment directly beneath the same. This water has found its way through the aperture 31 from the water compartment located directly beneath the reservoir 22. The cylinder surrounds the fan and motor and is provided with a pair of rings 39 and 40 located side by side and spaced apart by inner and outer meshed wire rings ll-and 42 respectively. Provided the filling material is somewhat light, additional netting similar to mosquito netting (not shown), may be placed against the inner and outer cylinder rings 4| and 42. The filling material which is located between the four walls defined by the rings 39 and The supplemental water absorbing material such as excelsoir, spun rubber excelsior or spun metal. n fact any substance that will permit liquid to evaporate from the such substance when air is passed through or around it. The meshed wire rings are attached to the cylinder rings by solder, welding or other suitable means of attachment, although we prefer to make the outer meshed wire ring 42 removable so that the filling material 43 may be removed or replaced at suitable intervals. The outer peripheries 44 and 45 of the rings extend beyond, or are of greater diameter than the meshed wire ring 42 to form the support of the cylinder 38 whereby the cylinder may be rotated by the means hereinafter described; The cylinder surrounds the motor and fan, and the rings 39 and are located fairly closely adjacent the front wall 4 and the rear wall of the casing when in position so as to prevent the passage of any great amount of air between the rings and casing walls. They are held from being in rubbing contact with the said walls by the rubber antirattlers which are mounted on both rings and serve to slightly space them from the said walls.

The motor shaft 41 is provided with a pulley 48 of general V-type construction. This pulley is located outside of the back portion of the casing as shown in Figure 3. Extending through the back of the casing are two other shafts, 49 and 5B, (FigureZ), which are driven by pulleys 5| and 52 respectively (Figure 3). These pulleys are also of V-type construction. These shafts 49 and 58 extend entirely across the casing from front to back and are provided with bearing supports 63 and 84. Mounted on each shaft 49 and are a pair of rollers having grooves 55 and 56 respectively. The said rollers are fixed to the shafts by any suitable means not shown. The

four rollers form driving surfaces for driving the cylinder 38. The outer peripheries 44 and 45 of the rings seat in the grooves 55 and 56.

58 is a belt which seats in the V-grooves of the pulleys 48, 5| and 52. This belt serves to drive the shafts 49 and 50 through the said pulleys when the motor 1 is running. Any suitable means may be provided for reducing the speed of the shafts 49 and '50 below that of the speed of the shaft 47. One means, as shown, includes the provision of a comparatively small pulley 48 and large pulleys 5| and 52 which are driver by the smaller pulley 48. When these shafts 49 and 50 are driven by the motor I, the cylinder 38 is rotated by means of the shafts 49 and 50 to cause the lower portion of the cylinder to dip into the water which has seeped into the pan H] from the supplementary reservoir 35, by means of the openings 31 in the partition wall 36.

The form shown in Figures 1 to 8 is that usually employed for air conditioning the interiors of building and supplying them with the proper amount of moisture laden cool air. The air enters through the meshed top 5, passes through the cylinder 38 and into contact with the material 43 therein, and is then drawn into the fan, after which it is forced by the fan through the opening 5 into the interior of the room.

In the form shown in Figure 8 the flexible conduit or rubber or other suitable material is attached to the vent opening of an automobile. This vent is usually located in the cowl or dash of the automobile. The air is conducted through the flexible conduit, thence into the interior of the casing 53. This casing is constructed in a similar manner to the casing shown in Figure 1.
