V4 claims. (c1. sis- 94) 'I'his invention relates to the art of ventilating appliances for buildings; and has reference more particularly to a special type of electric Ventilating fan known in the trade as a cooling 5 fan, the purpose of which is to cool attics and upstairs sleeping rooms by expelling the heated air collecting in such rooms during the dayunderA the heating eect of the sun's rays, and inducing an inilow ofthe cooler and fresh outside air. In accordance with the principle of this invention, and in the preferred embodiment thereof, an electric propeller ian, preferably mounted on a portable standard similar to the standard of a portable parlor lamp, is positioned opposite a window or other wall opening on the inner side of the latter, and a hood or adapter preferably of canvas or like exible materialtand having the character of a short section of hose is fastened at one end 'to the rim oi theusual fan guard and at its other end to a panell tted into the window irame preferably beneath the upper sash, the
' panel having an air discharge opening register-r ing with the Vother end of the hood oradapter,
so that the rear or suction side of the 4fan communicates only with the air in the room, and its front or discharge side communicates through the hood or adapter only with the outer air, said hood or adapter forming a discharge conduit for the air propelled by the fan. The outer side of the panel is preferably equipped with a louver cover-- ing its discharge opening to prevent rain from beating in." l i Among the Vobjects of the invention-are, 'to .provide a cooling appliance of the type described 5- that may be very easily and quickly mounted'in and removed fromY operative positionin relation to a window, to provide an appliance'that may be fully mounted without'requiring the use of nails or screws to attach it Vto the'window, to provide 40 such an appliance readily adaptable t'o various sizes and heights of windows, to provide an appliance that; for its installation, will not deface the window nor require any structural change therein, and, generally, tn provide a room cooling appliance of the characterV described that will be simple, inexpensive, and highly efficient for its intended use. 1
An improved embodiment of the invention is illustrated in the accompanying drawings in which- Fig. l is a perspective elevation, showing the device applied to what may be assumed to be an attic or upper story window of a dwelling.
2 is an enlarged vertical section through shown, a heavy base the device in the plane of the fan'axis, withtlie" motor appearing in elevation.
Fig. 3 is a vertical cross section on the line 3 3 of Flg. 2. e Fig. 4 isk an enlarged sectional detail through 5 the joint of vthepanel on the line 4-4 of Fig. 3.
Fig. 15 is a Afralglxlllllzaljylongitudinal section fthroughthe hood'oriidapter showing the means for detachably.securingthesame to the panel and the fan guard; n 1o Fig. 6 is' a perspective elevation of a spring wire ring employed to detachably secure one end of the hood or adapter to the panel.
Fig. 7 isV afragmentary sectional view of the vertically adjustable fan and motor support, illus- 15 tratingvone form'of adjusting means that may be employed.
In Fig. 1, III designates as an entirety a window that may be assumed to bel a window inthe. attic or an upper story of a dwelling.y vOn the 2W" iloor of the room served by the window Ill'is a portable fan support comprising, in the instance' plate II and lan upright pedestal or post preferably comprising. telescopfV` ing sections I2 and I3. 'As shown in Fig. '1, the upper section I3 telescopes within the lower section I 2 andis secured at any de siredheight by means of a split ring I4 encircling the inner sec-f tion I 3, and a nut I5 that has threaded engagement with the upper end of the lower section I 2. The lower portion I4 of the ring I4 has a tapering iit within the correspondingly tapered upper end of the section I2, and the upper portion I4" of the ring I4 also has a taper t with the correspondingly tapered inner surface of the upper portion o f.lthe n ut 1 5. When the nut is backed off suiliciently' toreli'eve'its compression on the splitring, the upper section I3 may be raised or lowered to the desired extent, and thereupon, by screwing the. nutdown, the two sections I2 o and I3 are locked against relative movement. An ordinary set screw orany other height adjusting means may be employ On the upper end of the post section I3 is mounted .an electric motor I6 of a well known type, to the armature shaft of which is directly connected a propeller fan Il. Attached to the motor frame and enclosing the fan I1 is a, wife guard designated'as anentirety by I8, ofanvell known typecommonly employedv with propeller 50 fans of this character. I The guard herein shown comprises mating halves I9 and 20, the peripheral rings of which are united, as shown inFig. 5, by spaced pairs of outer .and innerclamps ZI and v22 and a screw 23 efte ding through ahole in the 55 outer clamp 2l and engaging a tapped hole in the inner clamp 22.
A panel preferably comprising a pair of vertically jointed sections 24 and 24' is adapted to occupy the portion of the window opening underlying either the top sash or the raised lower sash. Preferably it underlies theA top sash, as shown, since, by removing the hood or adapter, the lower sash can be closed, leaving -the panel in place.
Referring to Fig. 4, one-of the panel sections, such as 24, is formed with a tongue 25, and the opposite edge of the other section, such as 24', is formed with a corresponding groove 26 that receives the tongue 25. The outer edge of the tongue 25 is beveled as shown at 21 so that the panel section 24 can be bent inwardly, as shown by dotted lines in Fig. 4, suiciently to enable the outer edges of the panel to pass the sash stops and enter the sash grooves of the window frame, and when so entered the two panel sections lie in the same plane, shown by full lines in Fig. 4. The panel is formed Witha central opening 28 (Figs. 2 and 3), herein shown as circular, onehalf of the opening being formed in one panel section and the mating half in the other panel section. As shown in Fig. 5,` the edge portion of the panel that encircles the opening 28 is formed with a groove 29 for a purpose later disclosed.
30 designates the hood or adapter which preferably consists of a short tubular section of canvas or like flexible material and has the function of a conduit for the air propelled outwardly by the fan. On the outer end of this hood 30 is formed a hem l3l that receives a split'ring 32 (Fig.
6) of spring wire. The `hem 2S and the wire 32 are sprung into the groove 25, the elasticity of the Wire ring holding the end of the hood in the groove. The ring 32 has a laterally projecting handle 33 that projects through a short cut-out 34 `(Fig. 3) in a side of the groove 29, so that when it is desired to remove the hood from the panel, this can readily be done by compressing the ring 32 sufficiently to spring it nut of the groove.
The other end of the hood 30 is also formed with a hem 35 (Fig. 5) that receives a metal band 36 of a size to t over the mating peripheral wires of the guard sections I9 and 20 and their outer clamps 2 I; and this end of the hood is attached to the fan guard by the same screws 23, which eiect a binding action of the clamps, all as clearly illustrated in Fig. 5. With the hood or adapter 3D thus secured at one end to the panel in register with the panel opening and at its other end to the periphery of the fan guard, it is clear that the hood forms a discharge conduit for the l warm airAdriven off by the fan, all of said air necessarily flowing through the Window opening to the outside, and the suction effect of the fan is limited to the air within the room.
For protection against rain, the outer sidek of the panel is preferably equipped with a. louver frame such as is best illustrated in Figs. 2 and 3, and designated as an entirety by 31. This louver overhangs and covers the panel opening, and the outer edges of the louver blades are preferably covered by ascreen 38. Where this louver is employed with a jointed panel such as described, one sidesection of the louver frame is permanently attached to one of the panel sections, such as 24, as by nails`39, while the other section of the louver frame is left free until the panel has been inserted in place and its two sections brought into a common plane. The other side of the louver frame is then secured to the other section of the panel as by screws 40, which bold the panel rigidly in place.
The device is readily removed from the window when its use is not required by first detaching the hood or adapter from the panel by compressing and removing the ring 32, and then, by withdrawing the screws 40, the panel itself may be ilexed and readilywithdrawn from the Window opening, if its removal is desired.
When this device is used to cool an attic or an upper story of a dwelling, it is associated in the manner described with one of the windows of the room to be cooled, all of the other windows of the same room being opened. Windows and/or doors of the main floor and/or basement are also opened, as also any doors of stairways between the attic or other room to be cooled and the lower rooms or basement. Thus, as the blanket of heat is pulled off from the upper floor or floors, fresh v cool outside air flows in through the other open window or windows and upwardly from the lower floor or iloors to replace the warm air driven oil, thus substantially lowering the temperature of the room or rooms served by the appliance and making them tolerable as sleeping rooms.
Structural variations in the details of the structure shown and described may, of course, be
resorted to without departing from the substance and scope of the invention as defined in the claims.
