ATTIC LOUVER Henry Avers and James W. Ground, Stillwater, Okla.

Application June 9, 1949, Serial No. 98,032

This invention comprises lnovel and usefulv irnprovements in attic louvors and more speciiically pertains to a Ventilation ,louver construction for Walls and the like, and generally consists of a louver `construction formed of angle iron members rigidly secured together to form a frame tolgether with a series of slanting, parallel vertically spaced `slats `carried by the frame together'with a screen secured thereto.

The principal object of this invention is to provide a ventilation louver of a sturdy butJ simple and inexpensive construction which will Asatisfactorily admit the passage of air therethrough but will prevent the ingress of rain, snow, the direct rays of the sun and the like.

A further object of the invention is to provide an improved louver construction which is ideally adapted for use with vertical walls or the like, and in Whichan improved screening is assembled as a part of the louver construction.

`A further object of the invention is to provide a louver construction as set forth in the foregoing objects which shall include a condensation and Water collecting trough for collecting Water impinging and condensing on the slats of the louver, and discharging the same exteriorly of the wall with which the louver is associated.

A still further object of the invention is to provide a louver construction which shall be formed of commercial angle iron structural units and which are assembled readily in an improved relation to lessen the Weightand increase the strength of the construction.

These, together with various ancillary features and objects ofthe invention whichwill later .become apparent asthe following description proceeds, are attained by this invention, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure l is an elevational View of a portion of the vertical wall of a barn or similar building with which the improved louver construction is associated;

Figure `2 is a horizontal sectional View taken substantially upon the plane of the section line 2-,-2 thereof, parts being broken away and omitted;

Figure 3 is a vertical transverse sectional View taken substantially upon the plane of the Asection line 3--3 of Figure 1, parts being broken away and omitted; and,

Figure 4 is an assembly perspective View of the various elements making up the improved louver construction.

5 ola-mls.v (o1. sas- 121) Referring now more Aspeeldcally to .the @06empanying drawings, wherein like numerals ,deS- ignate similar parts throughout the Various views, there is disclosed the improvedlouver construction indicated generally by the numeral `I 0 `mounted inoan opening of a vertical wall kI2 Awhich may form a part of a :barn or house or the like, it being understood that .the louver is customarily recessed .in this opening flush with the exterior surface of the Waller partition l2.

The louver construction I U includes top and bottom rail mem-bers I4 and lr6, which are of angle iron construction 4as are also vertical end members IB ,and 2D together with vertical intermediate members 22 and 24.

Considering first the intermediate members, it will be seen that these members `,maycon-veniently be formed of .U1-.shaped .channel ,members the web portion of which alie nllOYided With a series ofcoextensive vertically spacedand inclined slots z s which marne isposed atany Suitable angle such as orthe We, Ato-their upper and lower ends, the intelm late channel members lareV provided with horizontally diSPQSed flanges land .310 for a purpose Whichuwll `loe lar setirorth.

The end members ,t8 and '20 are of l-fshered cross-,section andare providedwith similar'coextensive vertically `space :diificliried slots 26, the endmembers at their upper and lower'extrernities likewise terminating Tin hlizbntally `disposed flanges `32 and 3 4. Whileithe slots 2S of thintermedate members `2z and .2`4extnld entirely through theseme'mbers, the `correspending `slots of the end members `Ill ,andV 2B may either be formed,as grooves `in theA surface of one wall of the aV gle iron `end members,4 or may comprise slots ertendiig therethrough ,as desired;v

.A plurality lslatsl having their )Sides ver# tending upwardly aS at 38 ,and downwardly as at-4 respectively have thesesides disposed `in ,any .convenient angle ,such aS in vertical planes; these slats beine dsposd'throuehthe `Slots-fifi 0f the intermediate membersuand `extemling into or through the slots 2B of the end memberswhere.- .by the ,slats are rmly mounted in overlapping relation to form vanes or shutters which slope .downwardly and 'outwardly `of the 'louver @91'1- structon, `as Shown nfFigures 1 and 3;

If desired, the ,slatsmay `be welded where they engage .any of' the end 0r intermediate members in order Ito 'increase the rigidity of` the constfllldudn. M y.

` The top and bottom rails I4 and I6 preferably comprise horizontal portions 42 and 44 which have respective vertically upstanding and de- 3 pending flanges 46 and 48 respectively which are adapted to be disposed substantially flush with the vertical wall surface l2 as will be seen from Figures 1 and 3. At what may be termed the inner side or inner end of the shutters, the top and bottom rails areprovided with Vertical flanges 50 and 52 which extend inwardly of the shutter. It isintended that the portions 42 and 44 shall be seated upon each of the flanges 28 and 32, and 30 and 34 respectively, and be Welded thereto to complete a rigid rectangular frame-V work.

In order to render the rectangular framework of the shutter more rigid, a gusset plate 54 may be welded to the joint formed between each of the end members and a top or bottom rail, as will be readily apparent from Figure 1,

It is proposed to further reinforce and strengthen the framework of the louver construction by adding reinforcing members to the vertical end members, these reinforcing members being likewise of L-shaped construction and being indicated generally by the numerals 56 and 58. Each of these members Vincludes perpendicularly disposed vertical walls 60 and 62, the walls 60 having perpendicular, outwardly extending vertical flanges 64 which are adapted to abut against and be welded to the laterally extending surface `of the end members I8 and 20 while the walls 62 are adapted to abut against and be welded to perpendicular, inwardly extending vertical flanges 66 formed on the walls 68 of the end members,

as shown in Figure 2. It will thus be seen that vision of the water collection trough disposed be- Y neath the bottom rail, and this trough may conveniently comprise a horizontally disposed plate l2 having an upstanding back or inner flange 14 with integral upstanding end flanges 76, and a depending outer or front flange 18. As shown best in Figure 3, the Vwater collection trough is mounted upon the inside of the wall in which the ventilated louver construction is disposed, with a Vvertical flange 'I4 disposed inwardly of the screening l0, with the plate 12 underlying the bottom railv I6 and with the forward flange 'i8 being welded or otherwise secured ,to the rear surface of the depending flange 48 of the bottom rail. Any suitable means may be provided for conducting moisture collected in this collecting trough to the exterior surface of the wall with which the louver is constructed.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art after 'a consideration of the foregoing specication and accompanying drawings, it is not desired to limit the invention to the exact 4 construction shown and described, but all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
