ELECTRIC FAN CABINET Filed April 14, 195? 2 sheets-sheet 1 A//l//ia/W/QQ/aaswf ATTORN EYS Patented Feb. 7, 1939 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to electric fan cabinets and has for an object to provide a cabinet having novel louvers for delecting the blast from the fan laterally to the right and to the left and up- 5 wardly and downwardly along paths which diverge from the4 axis of the fan blast so that the blast may be comfortably borne by a person sitting in front of the fan.
A further object is to provide a cabinet of this l character which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.
With the above and other objects in view the l invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the` spirit or sacrificing any of the advantages of the invention.
In the accompanying drawings forming part of this specication,
Figure 1 is a front elevation of a fan cabinet having louvers constructed in accordance with the invention.
Figure 2 is a cross sectional view taken on the line 2-2 of Figure 1 and showing the relative inclination of the louvers which extendlengthwise of the cabinet.
Figures 3, 4 and 5 are respectively longitudinal sectional views taken on the lines 3-3, 4-4 and 55, Figure 1, showing the relative inclination of the louvers which extend transversely of the cabinet.
Referring now to the drawings in which like characters of reference designate similar parts in the various views, I0 designates a cabinet having a door I I in the rear wall. The door is provided with an opening I 2 within which a wire mesh screen I3 is disposed to filter the air sucked into the cabinet by the fan I4. The ian is provided with brackets I5 which are secured by screws lli to a shelf Il that exten-ds from the rear wall I of the cabinet below the door. The cabinet is of suiiicient height to. nicely receive the fan blades I9, as best shown in Figure 2.
In further carrying out the invention the cabinet is provided preferably with three upper longitudinal louvers 20, 2| and 22 and also is provided with three lower longitudinal louvers 23, 24 and 25. The upper louvers are inclined obliquely upwardly to the axis of blast projection of the fan, and the three lower louvers are inclined obliquely downwardly to the axis of blast 28, 29 and 32 are disposed. The louvers on the opposite sides of the centermost louvers oi each row are inclined oppositely to each other, as best shown in Figures 3, 4 and 5 so that the blast from the fan will be directed laterally to the right and to the left of the axis of blast projection by these transverse louvers.
Substantially oblong closures 3l, 32 and 33 are arranged respectively at the center of the upper row of louvers 2li, at the center of the middle row of louvers 23 and at the center of the lower row of louvers 3U. The upper and lower louvers are provided respectively with oval openings 34 and 35 and with obliquely disposed slits 3E and 31. The center closure 32 is provided with an oval opening 3B. These closures with their openings arranged as just described restrict the too free exit of the blast from the fan at the center of the cabinet. Moreover, the louvers form long air lducts for directing the air streams positively in the desired directions at the source, without the disbursion which takes place where the air ducts are short as in previous constructions.
From the above descrip-tion it will be seen that the sets of louvers deilect the blast from the fan upwardly, downwardly, to the right and to the left of the axis of blast projection in small minute air streams so that a person may sit in iront of the cabinet with comfort.
What is claimed is:
In an electric fan cabinet, upper longitudinal louvers, lower longitudinal louvers, the upper louvers being inclined obliquely upwardly to the axis of blast projection, the lower louvers being inclined obliquely downwardly to the axis of blast projection, rows of transverse louvers in the spaces between the longitudinal louvers. the louvers on one side of the center of each row being inclined oppositely to the louvers on the other side of the center of the row, said louvers all forming long air ducts for directing the air streams positively in the desired directions at the source, and substantially oblong closures engaged in the spaces between the vertical median row of louvers having exit openings restricting the too free exit of the blast at the center of the cabinet.
