Application August 12, 1932, Serial No. 628,453

4 Claims. (01. 261-403) This invention relates to air cooling devices, systems, or arrangements adapted to lower the temperature in rooms, plants or the like by water cooled air, and it is the principal object of my 5 invention to provide a device of this character which is comparatively simple and inexpensive in its construction, yet durable and highly elicient in operation.

Another object of my invention is the provi- 19 sion of an air cooling device in which a plurality of frames holding water absorbing material are suitably arranged within a box or casing and are subjected to the influence or action of a current of .air.

A further object of my invention is the provi-- sion of an air cooling device of this type equipped with a suction pump delivering the water pumped from a suitable tank in suitably divided streams to the cloth frames, while the surplus of water is returned into the tank.

with the cooling air which is led against the moistened cloth or fabric sheets, and the motor driving the wind wheel or turbine is simultaneously adapted to drive the pump.

These and other-objects and advantages of my invention will be more fully described as the description thereof proceeds and will then be specifically defined in the appended claims.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a top plan view of an air cooling arrangement constructed according to my invention.

Fig. 2 is a sectional front elevation thereof. Fig. 3 is an end view, partly in section on line 3'3 of Figure 2.

Fig. 4 is a perspective view of a frame box.

Fig. 5 is a perspective view of one of the frames.

As illustrated, in a casing 10 of suitable size and material a suction pump 11 is arranged adapted to be driven from a motor 13 on a support 12 by means of a suitable belt.

A turbine, or wind wheel 15 is mounted on the shaft of the motor 13 and is inclosed within a sheathing case 14. This turbine, actuated by the motor 13, drives air into a wind box 16 which discharges into a chamber 19. Within the said chamber 19 frames 17 are arranged in spaced relation to each other and supported-by notched elements 18 which project from the walls of the chamber 19. These frames are held in position at their lower extremities by frictional contact with the walls of the said chamber. Pieces of linen, or water absorbing material 18 are held, or spread in the frames 17. A pipe conduit 20 carries water from a tank 21 to the pump 11 which forces the said water upward through the pipe 23 to discharge into a distributing pipe 24 which is set within the casing 10 and passes over the holding frames 1'7 and the linen, or water absorbing material therein supported. The pipe 24 is provided with a plurality of nozzles- 25 through which water passes to moisten the said water absorbing material. Surplus water is led back into the tank 21 through collecting grooves 26 which are arranged below the absorbing material, the final discharge being through the nozzle 27.

Water is filled into the tank by means of a filler nozzle 22, while it can be drained through the drain cook 28. The casing is supported by suitable feet 29 and a felt mounted cover 30 or the like can be employed to close the casing when not in use.

In operation, the motor is started to operate the pump driving Water from the tank to the upper part of the casing for distribution onto the fabric sheetson their frames through the nozzles 25. As the sheets are arranged in suitable frames 17 supported in the notch elements 18' they may readily be exchanged for cleaning and other purposes by lifting the said sheets and frames out of the casing. The motor will drive the wind wheel or turbine to drive air through the wind box against the moistened sheets where the air is cooled and then distributed into a room to be cooled through the opening in the top of the easing 10 when cover 30 is removed. The surplus of water is collected in grooves 26 and returned by means of the nozzle 27 into the tank, which can be supplied with water through nozzle 22 or drained through cock 28. The frames being arranged in an inclined position in their box will compel the air current to pass through them to thoroughly moisten the air. 7

It will be understood that I have disclosed the preferred forms of my device only, as one example, of the many possible ways to practically construct the same, and that I may make such changes in its general arrangement and in the construction of the minor details thereof as come within the scope of the appended claims without departure from the spirit of my invention, and the principles involved, so for instance I may make my device useful also for the winter to heat the air by for instance the building in of a suitable electric heating element or the like.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In an air cooling device, a casing having an upper opening, a motor driven suction pump in said casing, a wind box, a turbine wind wheel operated from said motor to drive air through said wind box, a chamber above said wind box, a plurality of frames, pieces of moisture absorbing material spread between bars of the said frames, said frames exchangeably supported in notch elements in said chamber, a pipe having a plurality of nozzles arranged in said chamber above the frames, a water tank, a pump, pipe connections between said tank and said pump, and between the said pump and the nozzles through which the water is pumped to moisten the material held in said frames, said chamber having a plurality of water collecting grooves in its bottom and a nozzle through which the surplus of water collected in said grooves is returned into said tank, and a felt lined cover over the said upper opening through which moistened air is driven by the operation of said wind wheel into a room to be cooled.

2. In an air cooling device, a casing, a chamber mounted within the said casing, a distributing pipe set over the said chamber, nozzles in the said pipe directed downwardly over a plurality of water absorbing pieces which are hung in frames supported in notch elements attached to walls of the said chamber, collecting grooves positioned below the said water absorbing pieces and inclined to discharge into a water tank thereunder, a wind box opening into the aforementioned chamber and the said box connected to receive air from a turbine which is actuated by an adjacent motor, a pump connected to be driven by the said motor and the said pump connected to draw water from the aforementioned tank and to force the said water through a pipe which discharges into the distributing pipe in the upper portion of the said chamber.

3. In an air cooling device, a supporting casing, a water tank mounted in conjunction therewith, an air driving turbine mounted within the said casing and actuated by an adjacent motor, a wind box connected to receive air from the turbine and to discharge the said air into an upper chamber where it contacts with water absorbing pieces which are hung in frames supported in spaced relation to each other from notch elements attached to the walls of the said chamber, a water distributing pipe set above the said frames and having nozzles directed toward the water absorbing pieces, an opening in the supporting casing over the said chamber and a felt lined cover set over the said opening, a pump, actuated by the aforesaid motor and the said pump connected to draw water from the aforesaid tank and to force the said water up through a pipe and into the distributing pipe, and collecting grooves positioned below the water absorbing pieces and the said grooves directed to discharge into the aforementioned tank.

4. In an air cooling device, a supporting casing, a water tank within the said casing, a wind box positioned in the lower portion of the casing and opening upwardly into a chamber in which are removably mounted a group of water absorbing elements, a grooved structure set below the said elements and inclined at an angle directed toward a discharging nozzle leading into the aforesaid tank, an opening in the supporting casing over the aforesaid chamber, a felt-lined covering over the said opening, a turbine set to drive air into the wind box, conducting means to carry water from the tank and to distribute the said water from the tank and over the absorbing elements, means to actuate the said turbine, and means to force the water through the, conducting means aforementioned, substantially as shown and described.
