LOUVER CONSTRUCTION Filed Dec. 30, 1957 RobeY A dersoh, by 77 is AttOT W ey.
Patented Aug. 9, 1-938 NITED STATES- woven oous'rauc'nou Robert G. Anderson, Erie, Pa., assignor to General Electric Company, a corporation of New Work Application m mber so, 1937, Serial No. learn 4i @laims.
'llhis invention relates to louvers, more specificaliy to louvers provided in openings in the side walls of railway locomotives for the purpose of permitting tree passage of air therethrcugh into the interior of the locomotive cab while excluding rain or snow therefrom.
in railway locomotives, openings are usually provided in the side walls to permit ventilation and proper circulation of cooling air therethrough. 'llhese openings are usually protected by louver arrangements to preclude'raln or snow from entering the cab and such arrangements, if effective, are'usually bulky and expensive to construct. The, louver blades are usually arranged in a framework and the entire assembly mounted in the opening.
it is an object oi this invention to provide a simplified louver construction which is light in weight, inexpensive in design and can be mounted directly on the wall of the locomotive over, the opening without the need of an additional supporting framework.
Fora consideration of what I consider to be novel and my invention, attention is directed to the following description and claims appended thereto in connection with the accompanying drawing.
In the drawing Fig. l is a perspective view' of a louver assembly embodying my invention; Fig. 2 is a cross-sectional view taken along the line AA of Fig. 1.
Referring to the drawing, l0 indicates a side wall of a locomotive having a rectangular aperture i'l therein. Extending across the aperture and secured preferably to the inner surface of the wall ID are a plurality of louver blades l2 constructed according to my invention. These blades may be formed from straps of flat metal cut to a suitable length greater than the length ofthe opening across which they are to extend, Theend portions id of the blades are offset, as shown, preferably along the longitudinal axis of the blades as at M, a distance equal to the thick, ness of the stock, so that the'plurality of blades may be assembled in an overlapping relationship, the end portions extending parallel with the wall In. The central portions ii ofthe blades extending across the aperture are twisted or deformed about the longitudinal axis so that these portions lie in parallel planes at a suitable angle with respect to the plane of the wall I0 according to the amount of opening desired. These blades may be secured in position over the aperture by bolts through the end portions and the adjacent wall ID or, if used in a railway loco-.
5 As viewed from the outside of the locomotive or from the left in Fig. 2, it is seen that free passage of air is permitted through the louver assembly into the interior of the locomotive, or to the right. However, due to the overlapping relationship of the blades, rain or snow will be substantially precluded from passing therethrough.
Having described my invention in what I now consider to represent the best embodiment thereof, I desire to have it understood that the spacific example shown is only illustrative and that the invention may be carried out by other means.
What I claim as new and desire to secure by Letters Patent of the United States is:
1. In a louver, the combination including a sheet metal wall having an aperture therein, a louver blade extending across said aperture, the ends of said blade being secured to the wall at the edges cfsaid aperture. the section of said blade extending across said aperture being deformed with respect to said end portions thereof so that the opposite edges of said section lie in a plane at an angle with respect to the plane of said wall and onopposite sides thereof, a second blade extending across said aperture, the ends thereof overlapping the ends of said first blade and secured to said first blade and to said wall, the central section of said second blade lying in a plane parallel to and spaced from the corresponding section of said first blade.
2. In a louver, the combination including a wall having anaperture therein, a louver blade extending across said aperture, the ends of said blade secured to said wall adjacent said aperture, the section of said blade extending across said aperture being deformed about the longitudinal axis with respect to said end portions so that said section lies in a plane at an angle with respect to the plane of said wall, a second louver blade extending across said aperture and secured to a said wall, the ends of said second blade being provided with ofisets longitudinal of the blade so that the offset portions of said ends overlap portions of the ends of said first blade, the central section of said second blade lying in a plane parallelto and spaced from the corresponding section of said first blade.
3. In a louver, the combination including a sheet metal wall having an aperture therein, a
louver blade extending across said aperture, the
endsof said blade being secured to said wall adjacent said aperture with the section of said blade extending across said aperture being deformed about the longitudinal axis with respect to the end portions thereof so that said section lies in a plane at an angle with respect to the plane of said wall, a second blade parallel in all planes to corresponding planes of said first blade extending across said aperture, the ends thereof being provided with ofl'sets so that the ofiset portions of said ends overlap portions of the ends of said first blade, the end portions of said second blade being secured to said first blade and to said wall.
4. A louver assembly for extending across a wall aperture comprising a blade, the mid-section of which is deformed about the longitudinal axis with respect to the end portions so that the opposite edges of said section lie in a plane at an angle with respect to the plane of said end portions and on opposite sides thereof, a second blade having end portions overlapping the end portions of said first blade and secured thereto, the mid-section of said second blade deformed about its longitudinal axis with respect to its end portions and lying in a plane parallel to and spaced from the corresponding section of said first blade.
