invention relates primarilyto *a householdtemperature changing device such as a cooler.

The chief objectof'this'invention is to provide a low operating costtemperature changing device such as a cooler and one which discharges laterally inall directions.

Another chief object of this invention is to providesuch a temperature changer at a comparatively low cost due to its simplicityof construction.

The chief feature of the present invention resides in providing a large heat transfer surface, disposing thereabout an enveloping wall to form an enclosing channel, the latter being substantially open at opposite ends for opposed directional air supply thereto, the wall having air discharge openings intermediately disposed for 'discharge of temperature changed air substantially in all directions about said surface and from air supplied at both ends.

Other objects and feature of the invention will be set forth more fully hereinafter.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Fig. 1 is a central sectional view of an embodiment of the invention, the motor being shown in elevation.

Fig. 2 is a top plan view.

By way of example only and not in any sense by way of limitation, in the lower part of Fig. 1 there is illustrated a base Ill of the desired ornamentation and outline. Within the same is suitably supported an electric motor ll of slow speed and small capacity. Also, therein if desired is a track l2 upon which bears plate l3 of the heat transfer device proper. To facilitate rotation thereof rollers, etc. l4 may b suitably included therebetween, Shaft l5 of the motor II is suitably connected directly (or indirectly) to shaft "5 depending from plate I3 as by coupling IT. The side wall of base I 0 may be louvered as at l8 and the bottom may include suitable feet or glides l9 if desired.

Whatever form the base may take, there is rotatably supported thereby the heat transfer device including this invention. Herein indicates the lower plate, which is of sufficient area to cover the top of the aforesaid base structure even though it rotates relative thereto because it is rigid with the plate 13 which is rotated.

Supported by the plate .l3 and coaxial therewith and rigid with the plate 20 is a well 2| of circular form and open at the topr same is closed by aconventio'nal insulation type cover 22 if desired} Said well is adapted to receive ice as illustrated.--'- v ,7 Concentric with-the well an'dcoextensive therewithis'a cylindrical shell 23 which is louvered at as illustrated. The p1ate20 is apertured at 25 outside of the well outline and the stock form ing said aperture is turned -upwardly as at--26. Surrounding the resulting peripheral series of projections and located. and retained thereby is said louvered cylinder 23.

The fit may be of friction type with the fingers 26 initially directed outwardly for retention of the cylinder or the latter may be suitably secured thereto by one or more screws not shown or by spot welding.

Operation With the well filled with ice and covered if desired, shaft I6 is rotated to produce rotation counter-clockwise in Fig. 2 or in such manner that the louvers create a suction effect 011 outlets thereof. Accordingly ice cooled air discharges laterally from the louvers and outwardly and entirely around the device.

This air so discharged is replaced in the annular heat transfer channel by air entering at the open top thereof and by air entering through the lower plate apertures 25. The air circulation is indicated by appropriate arrows in Fig. 1.

The ice in the well chills the well wall and same in turn chills the air in the heat transfer channel. Whenever desired, or required there may be carried by the base an annular trough 30 so that moisture condensate collecting on the exterior of the well and dropping through the apertures 25 will be collected by the trough and suitably disposed of if not re-evaporated.

Whenever desired, by slight changes, the well may contain a source of heat and the device herein illustrated will then function as an air heater instead of an air cooler. In that event trough 30 will be unnecessary unless the heater be of the solid fuel type and the trough be utilized for ash collection.

While the invention has been illustrated and described in great detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character.

The several modifications described herein, as well as others which will readily suggest themselves to persons skilled in this art, all are considered to be within the broad scope of the invention, reference being had to the appended claims,

The invention claimed is:

1. An air heat transfer device including a central well, a wall thereabout and appreciably spaced therefrom and forming a heat transfer channel about the well, the wall having a pluralit of longitudinally directed louvers, the channel having air inlets at opposite ends, the well being arranged for heat transfer purposes, and a means for rotating both well and wall to effect air circulationthrough-{the channel and" lateral and peripheral discharge from the louver'e'd wall;

2. A heat transfer device of the air cooling type as defined by claim 1 wherein the well is at a temperature sufiicient to-condense airborne moisture, a collector disposed contiguous to and below the wall, the wall louvers at" their loweren'ds discharging moisture condensing thereon to thesaid collector.

3. An air heat transfer device comprising a central well, a wall thereabout and appreciably 'spaceditherefrom. and forming a heat trans-fer "channel about the" Wall; the; channel; having air inlets at opposite; ends; the well being. arranged for heat transfer purposes, the wall having ,a'plurality --o'f longitudinally directed peripherally spaced: louvers, and: a: means for rotating both well and--wal-l to effect an air circulation through "formed on the plate from stockprovided=.=by the aperturing, said projections locating said wall in predetermined relation to the apertures, same serving as the lower inlets.

4. A heat transfer device as defined by claim 3 wherein the wall and projections have a wedging fit therebetween.

5. An air heat transfer device comprising a central well, a wall thereabout and appreciably spaced therefrom and forming a heat transfer channel about the wall, the channelhaving air inlets at opposite ends, the well bei'ngarranged. for heat transfer purposes, the wall having a lurality of longitudinally directed peripherally spaced louvers, anda means for rotating both well and wall to effect an air circulation through the'channel and lateral and peripheral discharge from the lowered wall, the wall louvers being di- REFERENCES CITED The following :references' are of record in the file of this patent:
