Application filed January 7, 1924. Serial No. 684,777.
This invention relates to an improvement in window ventilators, and the general object of the invention is to provide an allmetal louver plate and screen of sectional form and construction adapted to be readily fitted within window frames of different width, and when so mounted to present an attractive appearance viewed from either side. The respective sections when assembled are also adapted to be securely fastened in place within the window-frame beneath a sash so that the ventilating device may not be readily removed from the outside, and the sections are also particularly constructed to permit free and unobstructed ventilation over relatively large areas while giving full and adequate protection against driving rains and stormy weather.
In the accompanying drawings, Fig. 1 is a front or outside view of a window equipped with my improved ventilating device, and Fig. 2 is a rear or inside view of the same installation. Fig. 3 is an enlarged horizontal section of the window and ventilating device on line 3-3 of Fig. 2, and. Fig. 4 is a vertical section on line 4.4 of Fig. 2. Fig. 5 is a perspective view of three ventilating sections separated, and Fig. 6 is an enlarged perspective view of a corner portion of the louver screen section. Figs. 7 and 8 are outside and inside views respectively of a relatively wide window frame fitted with a pair of louver screen sections, a pair of end sections and a middle connecting section.
Fig. 9 is a rear or inside view of the sections shown in Figs. 7 and 8, but separated.
The ventilator comprises a panel or plate 2 made of relatively thin sheet-metal having a number of vertical rows of elongated louver openings 3 pressed or stamped therein, the projected portion 4 being rounded to make it stiff and rigid, and to provide a relatively deep opening and recess and a prominent water-shedding surface. The straight upper and lower longitudinal border portions of plate 2 are bent at substantially right angles to the plane surface of the plate to provide lateral seating flanges 5 and 6, respectively, which extend in the opposite direct ion to the projected louvers portions 4 and. the free edge portions 7 of these flanges are reverted part way to provide longitudinal grooves or channels 8 which are open at both ends and also spaced apart and open oppo- Silo the inner face of the plate. Plate 2 is al o folded inwardly at each end for a portion of the distance between the upper and lower flanges, a wide lip 9 being formed at each end of the plate to overlap and fasten the metal frame 10 of a fine wire-mesh screen 11 laid flat against the inner side of plate 2 opposite all the louver openings 3, thereby closing said openings'to the entrance of flies and insects. of flanges 5 and 6 are spaced apart for the screen frame 10 to permit the admission at each end of plate 2 of a pair of complementary end sections 12. These end sections are constructed exactly alike and are. also made of sheet-metal, being folded or bent at substantially right angles at top and bottom to provide short straight horizontal flanges 15 adapted to occupy and slide within the channels 8 formed in plate 2 by its flanges 5 and 6 and their reverted folds 7. A vertical flange 16 is also formed at the outer end of each section 12 by a double fold in the sheet metal, which flange isadapted to engage and lie flat against the upright 17 of the window frame and to be fastened thereto by a nail or screw 18 passing through an opening 19 in flange 16, see Fig. 3. The in ner end of each section 1-2 is cut away be: tween the top and bottom flanges 15 to narrow the section centrally so that the end rows of louver openings 3 in the louver screen section 2 will remain uncovered when a pair of such end sections are slidably connected with the louver screen section and all three sections are fastened in place within a window frame. In brief, the end sections have extended top and bottom flange portions to effeet a firm and stable connection with the louver screen section 2 while the central part is narrow enough to prevent any substantial overlap and closure of the louver openingsat the opposite ends of plate 2. The incurved edge 20 of each end section 12 is also bent or flanged to stiffen this sheet-metal member and to provide finger-holds for sliding the sections toward or apart from each other in removing the device from or fitting it to a window frame. v
Extra wide windows are fitted readily by employing two or more louver screen sections 2, two extensible end sections 12, and a supplemental section 21 having the form of the capital letter I, see Figs. 7, 8 and 9. Thus, section 21 is narrowed at its center and widened at top and bottom where it is provided with strai ht flanges 22 corresponding to flanges 15 0 end sections 12 to permit The reverted folds 7 the meeting ends of a pair of louver screen sections 2 to be joined slidably together. Sections 2 and 21 may be screwed or nailed to the window sill if desired, and the window sash may rest upon the joined sections, or the ventilating device may be placed within the window frame in front of or rearwardly of the vertically-movable sash.
What I claim is:
1. A ventilating attachment for windows, comprising a p'air of louver sections, a detachable I-shaped connecting section for the meeting ends of said louver sections. and an extensible end section for each louver secs tion.
2. A ventilating attachment for Windows, comprising a pair of screened louver sections having top and bottom border flanges, an intermediate connecting section of I-sha e having flanges slidably interconnected w1th the flanges of said louver sections, and extensible end sections having horizontal flanges slidably interconnected with the flanges of said.
louver sections, each end section formed with a flanged incurved inner vertical portion.
In testimony whereof I afliic my signature hereto. 1
