. -This invention relates to lamps and particularly .toa novel construction "and. arrangement for circulating the air adjacent thereto and within a rooinwhere lamps so constructed may be positioned. r

It is:a well-known fact that when seated alon side of a lamp as, for example, a floor or table lamp, one may be very'uncomfortable, especially in warm weath'en due to theheat generated by the-light bulb or bulbs inthe lamp. I M

, An. object, therefore, of the present-invention .is .to provide a novel construction and arrangement whereby theair adjacent the lampmay be circulatedin a manner to dissipate :the heat generated thereby. 1 1 Another object of the invention-"is to provide a novel arrangement wherebyair adjacent the base of the lamp may be circulated and directed .toward a person near the'lamp toproduce acooling effect. r V 7 Another-object of the invention is to provide a novel construction and arrangement for circulating. a portion of the air through a portion of thelamp body or support and direct it upwardly past: a light bulb or. bulbs mounted thereon and away from a. person 7 or persons' seated alongside the lamp, v1. I 1-..1-

A further object of the in-vention-is to provide .a. structure whereby: air may belcirculated in either an upwardly :or downwardly'directionas may be desired.

A still further object-of the invention is to improve devices of the character described in sundry details hereinafter-referred to and particularly pointed out in the appended claims. One embodiment of the 'presentinvention is shown for illustrative purposes in the accompanying drawing, in which: 1 I r l Fig. 1 is a sectional elevational view through a lampstructure and base therefor embodying features of the present invention; 1: .Fig. 2-is a plan-view partly in section of 'the base portion ofthe lamp illustrated in Fig.-"1, and'taken substantially as indicated-by the'line 2--2 thereof; 1 l 1 Fig. 3 is an enlarged plan sectional view taken substantially as indicated by line 3'3 of Fig. 1; d I V;

Fig. 4 isan enlarged plan :view partly in section of the portion of the base-illustrated in Fig. 1, 'and'taken substantially as indicated by the line d-fl thereof.

The illustrative embodiment of the present invention shown in the drawing comprises a base member indicated, as a whole, by the numeral 5 'base. :Positioned in the chamber I is an upwardly and and "upper compartments chamber 1 the base member 5 having a the main chamber 6, preferably, through a, plu- "rality. of'apertures 8 formed in the upper wall i of hollow form to provide a main chamber 6; the :upper portion of chamber 1 formed therein communicatingwith its lower portion and with discharge openings 1 I communicating with the atmosphere outside the outwardly inclined. baffle plate 12 forming lower l3 and M, respectively,

within the chamber 1, thebaffle plate 12 being provided with a plurality of apertures l5 ,for providing communication between the respective compartments l3 and l4. 2

.. .Mounted on the base 5 and extending upwardly "through the upper wall portion IB of the .disposed'hollow elongated lamp supportingcol- .umn I! having a lamp socket t8 mounted adjacent its upper end portion adapted to receive a lamp ['9 shown, in the present instance, as an electric bulb and extending upwardly through the 001- umn I1 isa conduit 2| for carrying the electrical conductors to the lamp socket IS, the conduit 2] being of substantially less diameter than the inner diameter of the column I! for providing a substantial space or air passage within the column.

Removably mounted within the main chamber 6 of the base member 5 is a fan 23 adapted to be driven by an electric motor 24 having suitable electrical connections 25 operatively connected through a switch 26 with a suitable source of electrical energy by which the lamp I9 is operand compartment i4 is a vertically ated, the fan 23 and motor 24 being shown, in

the present instance, as mounted in a bracket indicated, as a whole, by the numeral 21 and formed of oppositely disposed portions 28 and 29 adapted'to be clamped together by means of bolts 3| and- 32 for removably securing the motor 24 and fan 23 in suitable position within the chamber 6.

As clearly illustrated in lower end portion of the lamp supporting column I1 is provided with a plurality of apertures- 33 communicating with the compartment l4 and provided with upwardly and inwardly inclined deflectors 34 positioned above the apertures I 5 of the bailie plate l2 in a manner to receive air therefrom and direct it into the interior of the column l1 and into the space between the inner surface thereof and the conduit 2|.

Figs. 1 and 2, the

The column I1 is also provided, adjacent its upper end portion, with a plurality of apertures 35 having a plurality of upwardly and outwardly inclined deflectors 36 associated therewith for directing the air from within the column outwardly and upwardly past the lamp socket l8 and bulb IS in a manner to carry the heat generated by the bulb upwardly as, for example, through a shade member 31, and away from a person sitting adjacent the lainp. V V

As illustrated in Fig. ,1, the outerannular wall of the chamber 1 and compartment I 3 is provided with a plurality of openings 38 adapted to communicate with the atmosphere surround ing that portion of the base member 5.

It will be observed from the foregoing description that through the operation of a suitably connected switch 39 the light bulb i9 turned on and off, and,'if desired, through the operation of the switch 26 controlling the motor 24 and fan 23, air currents may be drawn from the lower side of the base 5 and circulated upwardly and outwardly through the openings l I formed therein and through the apertures 8 into the compartment I3, from which a portionof the air currents will be directed upwardly and outwardly by the bafile plate I2 and through the openings 38 into the atmosphere adjacent the lamp, and the air currents passing through the apertures I 5 of the baffle plate into the chamber I4 will be directed by the deflectors 34 through the apertures 33 formed in the column I! andinto the interior thereof, and thence upwardly through the column to be directed upwardly and outwardly therefrom by the deflectors 36 through the apertures 35 in a manner to carry the heated air adjacent the bulb I9 upwardly through the top of the shade member 31 and away'from a person seated adjacent the lamp, thereby providing a comfortable atmosphere surrounding the lamp, and a cooling eifect produced on the air above and adjacent the openings II and 38 by the air currents directed therethrough.

Obviously, the present invention is not limited to the precise construction and arrangement shown and described as the same may be variously modified. Moreover, all the features of the invention need not be used conjointly as thesame may be used to advantage in variously diiferent combinations and subcombinations.

What I claim as new and desire to secure by Letters Patent is:
