My invention relates to a device for distributing air, and has for one purpose the provision of air distributing or c1rculat1ng means whereby a fan or its equivalent may be employed to distribute or circulate air 1n a room. Another object is the provision of an ornamental article of furniture in which a fan or its equivalent may be concealed. and protected. Another object is the provrslon of means for circulatingr air laterally 1n a roomat the level of maximum utility. Qther objects will appear from time to time 1n the course-of the specification and claims.

I illustrate mv invention more or less dlagrammatically ings. wherein:

Figure 1 is a front elevation; v Figure 2 is a. plan view, with parts broken away; v

Figure 3 is a similar plan view of a variant in the accompanying drawv form of the device;

Figure 4 is a section on the line 4 4 of Figure 3, and

Figure 5 is a plan view, with parts broken away` of a further variation of the device.

Like parts are illustrated by like symbols throughout the specification and drawings.

Referring to Figures 1 and 2, A generally indicates a cabinet, which may be supported upon legs or supports A1. The cabinetproper is shown as including the side elements A2, which mav be upward continuations of the leas A1. -Aa are lower transverse frame members which connect the legs A1 to the supports A2. The supports A2 are connectedat their upper ends, as by the transverse frame members A4, upon which may be supported any suitable cover A5. A6 indicates a closed back for one side of the housing or cabinet so formed. The space between the supports A2 may be filled by a plurality of vertical louvers A", which extend between the members A8 and A. The vertical louvers A7 may be placed in one portion of the front of the cabinet opposite the back A", the space bcing lled, for example, by horizontal louvers A8. In any case,the result is that the three exposed sides of the cabinet are entirely masked by louvers, horizontal or vertical, so

`sides of the cabinet and to flow that the contents of the cabinet cealed. f I

Mounted in any suitable manner, for example upon the bottom member A, is al motor diagrammatically illustrated as B, a motor shaft B1 upon which may be mounted the fan hub B2 which carries aplurality of fan blades B3. It will'be understood that a rotation of the fan blades will directv air may beloonforwardly through the'vertical and horizontal louvers aligned with the front of the fan, while air will be drawn into the housing through the louvers at the sides of the cabinet. In order to maintain a constant circulation of air through the housing or cabinet I may provide a baille plate A1 cut away as at A11 to form an aperture into which the 'fan blades may project. Rotation of the fan will draw l cabinet. D1, D1 indicate the blades of the fanv adapted to be rotated by said motor. In order to maintain a regular draft orcirculation of air through the housing or cabinet, I may rovidela vertical partition E cut away as at 1 to form an aperture conforming generally to the peripheryof a circledefining a path of the outer tips of the fan blades. Rotation of thev fan will draw air through this aperture, causing it to flow invthrough three out through the other three sides. The louvers C2 may lie in horizontal planes, or, if desired, they may be inclined upwardly or downwardly, depending u on the desired direction of air delivery. en so inclined they more effectively perform the function of masking or concealing the fan and motor, but even when in horizontal position, as shown in Figure 4,

they mask it sufficiently for ordinary purposes. y l

Referring to Figure 5, I position intermediate the vertical supports C a plurality of vertical louvers G, in place of the horizontal louvers in form of Figures 3 and 4. These vertical louvers are preferably inclined in order to erform their masking function.

It will e realized that whereas I havedescribed and shown a practical and operative device, that nevertheless many changes in size, shape, number and disposition of parts may be made without departing from the spirit of my invention. I therefore wish my drawings to be taken as in a broad sense illustrative or dia rammatic, rather than as limiting me preclsely to the details herein described and shown.

The use and operation of my invention are as follows:

I provide an air circulating lcabinet or housing which is an ornamental piece of furniture. By its size, it permits theemployment 'of a fan of larger diameter than is.

normally employed in circulating air in a room. The employment of a large and relatively slow fan, which delivers a large volume of Vair at a relatively small velocity, is a defiis limited to a more or less restricting nite advantage. A large fan is quieter and more eiicient thanl a ysmall fan, and the air delivered by it has a more eiiicient cooling ciiect. The delivery of a rapid flow of air by a small, high speed fan, is likely to evaporate all the perspiration of thev user. In such case the breeze will have'the ellect of a heating rather than a coolingbreeze. Therefore, the employment of effective and sightly concealing means, enabling the employment of a large and relatively slow fan, is definitely advantageous.

Referring tothe drawings, and for example to Figures 1 and 3, I employ a cabinet with a fan rotating about a horizontal axis They conceal the fan, thus makin the device more sightly.V And they protect t e fan, p reventing access to it by the lingers, and makmg it safe to use in a home in -which there are children.

I claim: f

-1. In an air distributing device, a multlsided housing having at east three of its sidesopen, a fan positionedcompletely v vlthin the housing and o rable to cause air to ow therethrough, an a plurality of louvers positioned in said ogen sides, one of said openings being locate on'one side of the fan and constituting an air inlet, and another of the openings being located on the opposlte side of the fan and constituting an air outlet.

2. In an air distributing device, a housing having openings therein throughout the greater portion of the superficial area of the housing and a closed fiat to a. fan located completely within the housing and dlrectmg air therethrough, some of said openings b eing located rearwardly of the fan and constltutinnr air inlets and another of said openings lymg `on the opposite side of the fan and vconstituting an a1r outlet, and a plurality of louvers inA each of said openings.

words, from the horizontal louvers of Figure 1 the air is directed almost directly laterally,

but may flare widely in a general lateral plane.

In the form of Fi the form of Figure 5, I substitute vertical louvers for the horizontal louvers. The ver, tical louvers reverse the function of the horizontal to the extent that the' air maybe re 1, 'I associate vertical i louvers wlth the orizontal louvers, andvin widely dispensed Vwhen takenvertically, but

or beams when taken horizontally. Y Y `The-commoi
