AndrewsfLos Angeles, Calif. Application April 23, 1949, Serial No. 89,222

My invention relates to a combination heater outlet and air circulator, and the objects of my invention are:

First, to provide a heater outlet and a hood above said outlet having :air propelling means therein which changes the direction of the rising heat from vertical plane to a horizontal plane, whereby heat delivered by a conventional wall heater or the like may be completely circulated throughout a room, which more quickly and uniformly heats the room;

'Second, to provide a combination heater outletand air circulator which prevents heat delivered from a heater'from becoming concentrated in one small area in a room;

Third, to provide a combination heater outlet and air circulator which prevents the heated air from going up the wall from the grille or a wall heater and depositing particles of dust on the wall, and discoloring the ceiling thereabove;

Fourth, to provide a combination heater outlet and air circulator of this class which may be readily controlled by means of a conventional thermostatic switch or. the like;

Fifth, to provide a combination heater outlet and air circulator of this class which may be used in summer and winter for the purpose of circulating air in a room;

Sixth, to provide a combination heater outlet and aircirculator of this class which forces warm air horizontally into contact with various objects in the room which more evenly and more quickly heats the room, as compared to a direct thermal rise of' the heat from one location to the ceiling and subsequent spreading of the heat over the area of the ceiling of a room; and

Seventh, to provide a combination heater outlet and air circulator of this class which is very simple and economical of construction, efficient I in operation, and which will not readily deteriorate or 'getout of order.

With these and other objects in view, as will appear hereinafter, my invention. consists of certain novel features of construction, combination 7 and arrangement of parts and portions, as will be 2 Claims. (01. 9s1 0s) 2 circulation of air through my combination heater outlet and air circulator; Fig. 3 is a partial plan view and horizontal section as seen on the line 3--3 of Fig. 1; Fig. 4 is an inverted plan view taken on the line 4-4 of Fig. 1; Fig. 5 is a view in cross section and elevation with portionsbroken away as seen on the line 55 of Fig. 1 in the direction indicated by the arrows; and Fig. 6 is a detail in section and elevation as seen on the line 66 of Fig. 5 in the direction indicated by the arrows.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The heater outlet grille I, hood 2, motor casing 3, fan 4, and motor 5, constitute the principal parts and portions of my combination heater outlet and air circulator.

The heater outlet grille I may be the grille of a conventional wall heater, radiator or other heat delivering device, which is normally placed .adjacent a wall A, as shown in Fig. 2 of the drawing. Positioned directly above the grille l is the hood 2, which is elongated and extends horizontally in overhanging relationship with the grille I and therebeyond at opposite ends 20!. and 2b of said hood 2. lhe hood comprises a top wall 'a'extending between the ends 2a and 2b, a front wall I), and a back wall 0; the intermediate portions of the top wall a and back wall 0 constituting portions of the motor casing 3 which further includes a bottom wall at projecting forwardly of the lower edge of the back wall 0 to a point intermediate the back wall .0 and front the bottom wall at to form the ends of the motor casing.- The frontal portion of the motor casing comprises a vertical Wall 1 extending upwardly from the forward margin of the bottom wall d to the hoodtop wall a and which wall f constitutes the inner end of a cylindrical horizontal fan housing 3d which opens to the front of the hood; the wall forminga partition between the motor .and the fan housing. The motor casing 3 and the fan housing 3d are thus arranged substantially in the center of the hood with the motor casing in the rear portion thereof formed by the walls a, c, d, e and J which substantially encase the motor except as to the openings 3a and 3b. Enclosed in the hood 2 by means of the motor casing 3 is the motor 5, having an extending shaft Ed on which the fan 4 is fixed. The motor casing 3 is provided with air circulation openings 3a and 3b formed in the walls a and 6 respectively, adapted to provide air circulation sufficient to cool the motor when in operation; the opening 3a being disposed in the wall a immediately above the motor 5 and the opening 322 being disposed in the wall f immediately above the bottom wall (1 and leading to the interior of the fan housing 3d. The lower side 2c of the hood 2 is open substantially throughout toward the grille I, and is adapted to receive air thermally rising upwardly as indicated by the arrows B in Fig. 2 of the drawings. The lower portion of the fanl hous'ing is :provided with an opening 30, communicating the interior of the hood 2 at its lower .side 20, all as shown best in Figs. 5 and 6 of the drawings.

The hood 2 and the walls of the motor casing 3 and the fan housing 361, may be made of sheet metal, if desired, or any other suitable material, and maybe :fixed on the wall A at any desired distance above the grille i for the purpose of uniformly circulating warm air throughout the room in which the 'hc'od 2 is positioned.

The operation of any combination iheater :outlet and warm air :cireu'lator is substantially :as follows:

When the warm air,-a-s indicated Lby arrows :B, rises from the source of :heat or through the heater outlet grille I, operation of the fan 4 creates a vacuum at the opening do in the .motor casing 3, tending to force all of the warm air passing upwardly from the grille i, which is forced from the fan 4 in a horizontal direction with considerable velocity, which causes the "warm air to impinge upon and pass through various articles, such as tables and furniture, or the like, whicli directly heats lthe :variou-sportions of 5116"0'0111 and-articles therein by .con-

:duction, and maintains heat at a normally 110wer level sooner than would be :expected if the warm air were permitted to rise "to the :ceiling directly from the grille I A-conventional ther- 'mostat '5 may be:prov'ided for controlling the-.op-

eration of the air circulator, including the=motor '5- an'd the fan iaand it is -.obvious that ithe fan kin-a position at the inner surface of the wall may be used as-an air circulating :clevice-in warm weather 'for driving cool air when the source of heat inwardly of the heatersoutletigrille is inoperative.

It avill ibe :noted that arrows indicating :the passage 1 of air through the openings 13a and 53b Though Ihave shown and described-a Lparticular construction, combination and arrangementof par-tsand portions, Ido not wish atovbe limited to this particular construction,.combination' and arrangement, but: desire .to;include:1in=.the scope ofmy invention theconstruction, combination andzarrangement substantially sasvset forth in the appended claims.

Having thus tdescribed my invention, what I 4 claim as new and desire to secure by Letters Patent is:
