AWNING FAN Filed Oct. 25, 1940 Patented June 24, 1941 UNITED STATES. PATENT OFFICE 2,247,276 AWNING FAN Opal W. Chase, Little Rock, Ark.
Application October 25, 1940, Serial No. 362,738
3 Claims.
This invention relates to means for accomplishing room ventilation, and has particular reference to a device of this character which is of unitary construction and designed so that it may be quidkly attachable or detachable in order that it may be quickly and easily placed when the need therefor arises and may be as readily removed and stored as during the winter months.
It further relates to such a device which is inherently adapted to draw off the warmer air of theroom and which will cooperate readily with the ordinary window construction in accomplishing not only the major purposes of the device, but in its regulation to conform with conditions existing.
The objects of the invention'are:
To malre a device which is of unitary construction which may be readily attached for use, and detached for storage, and which is simple in construction and effective in operation.
The means by which the foregoing and other objects are accomplished and the method of their accomplishment will readily be understood from the following specification upon reference to the accompanying drawing, in which:
Fig. l is a sectional side elevation of the device installed.
Fig. 2 is a sectional front elevation taken on i the line ill-II of Fig. i.
Fig. 3 is a sectional plan taken on the line LlII-III of Fig. i.
Fig. l is a sectional side elevation showing a modified form oi construction; and
Fig. 5 a section taken on the line V- V of Fig. 4.
Referring now to the drawing in which the various parts are indicated by numerals:
ii is a typical window frame having usual upper and lower sash it, it respectively, the upper sash it being shown in all the views in iully lowered position.
Ell indicates a typical form of fan motor with vertical shaft driving a usual type of horizontal fan iii, this fan being disposed in a circular opening it through a horizontal diaphragm or plate 233.
In Figs. 1, 2 and 3 the diaphragm or plate 23 is secured to and supported by a metal awning construction having side walls 25 and a sloping top or roof 21?, the side walls depending past the diaphragm or plate 23 and being secured thereto as by fasteners such as nails or screws 29, or otherwise as may be desired, and the topwall being downwardly bent at its outer edge to form a valance 3i, likewise depending below the diaphragm and secured thereto. The side and roof walls of this awning structure are secured to a peripheral frame work comprising a horizontally disposed top bar 33 and depending side bars 35, these bars being assembled and joined in unitary manner to form a frame structure adapted to lie flat against the window frame it. The side bars have keyhole openings ti therein which are adapted to be seated over the heads of screws or bolts it secured into the window frames and after such placing to be slid downward into interlocking engagement with such screws for the support and anchorage of the structure to the window frame.
The fan it has an upwardly extending post ii with an. inclined upper end plate it rigidly secured to the roof portion 2? of the awning, as by rivets it, or otherwise as may appear desirable.
In Figs. 4 and 5 a structural metal frame work of side angle bars ill, and center channel member id connecting the upper bar ii-qi. and the diaphragm or plate i3-A, and a covering of canvas or other cloth ti, has been substituted for the metal awning construction described, the plate iii1i. oi the supporting column tit-d of the fan motor li--A being secured to and supported by the channel tit. In either form of the device the awning and fan assembly are a unitary structure or unit adapted to be en.- gaged and disengaged from the window.
The window is prepared for the reception of the ventilating unit by placing the tour bolts or screws ti! in suitable position to register with the keyhole openings of the unit to be used therewith, this being done by positioning the unit as it is to be supported and marking through the keyhole openings or by placing and marking through a templet on which the bolt locations have been cut, or the position of these screws may be determined by direct measurement. The screws or bolts are then secured in the window frame with sumcient space left beneath the heads thereof to accommodate the thickness of the side bars it and the window is ready for placing of the awning. This placing is done in obvious manner by bringing the larger portion of the keyhole openings it over the fastener heads and against the window frame and then allowing the unit to descend by its own weight or forcing it down into interlocking engagement.
In making use of the device the upper sash of the window is lowered and the motor connected as through a suitable wiring connector 53 to an electric circuit,- ordinarily within the room itself. The current is turned on and the fan placed in operation drawing air from the inside of the room adjacent the ceiling and dischargingit through the diaphragm or plate outside of the building, the adiacency of the diaphragm to the ends of the fan blades insuring that the air will be drawn from the room rather than merely circulated around the outside ends of the blades as would otherwise be entirely possible. Preferably the connector 53 is of such length that the upper sash of the window may be raised to substantial closure without disconnecting it.
The awning largely, if not entirely, conceals the working parts of the device or even their existence and protects the working parts against exposure to the elements. Under usual conditions of window uniformity the unit may be shifted between any of several windows should it be so desired.
. It will be understood that the appearance and detail of the device, particularly the attaching means may be varied without departing from my invention.
I claim:
1. In ventilating means for use with a window opening having frame members, a unit comprising an awning structure, a motor driven fan carried thereby and means for detachably securing said unit to said frame member; said awning structure including side bars spaced apart and a transverse top bar secured thereto, a. roof secured to said top bar, extending forwardly and downwardly therefrom and terminatingin a substantially vertical valance, side walls secured to said side bars and said roof and depending from said roof substantially to the bottom level of said valance and a diaphragm having a circular opening therethrough, said diaphragm being intimately secured to said roof valance and the lower portion of said side walls; said fan unit including a supporting bracket secured to said roof, and a vertical shaft motor supported by and depending below said bracket, said motor shaft carrying fan blades substantially at the level of said diaphragm. said diaphragm opening being vertical shaft motor. f
concentrically disposed with relation to said fan shaft and of size to loosely surround said blades.

3. The combination with a window casing of air withdrawing means including a housing structure adapted to be detachably secured to said casing, and a motor driven fan carried by said structure; said structure comprising a vertical, centrally open frame, a plate member secured adjacent the bottom of said frame and extending outward therefrom, a roof secured adjacent the top of said frame, extending forwardly and downwardly therefrom and secured to the outer edge of said plate, and side walls secured to said roof, the sides of said frame, and the side edges of said plate; said fan comprising a vertical shaft motor, fan blades carried by said shaft and extending outward therefrom and means supporting said motor fromsaid structure with said fan blades substantially at'the level of said plate,
said plate having a circular opening therethrough concentric with said shaft and loosely surrounding the ends of said blades; said frame having openings therethrough and said casing having complementary projecting members adapted for interlocking engagement with said openings to detachably secure said frame to said casing.
