BURNS, OF KENILWORT ILLINOIS, ASSIGNOR TO CHAMBER-LIN METAL WEATHERSTRIIP COMPANY, OI DET OI'I, MICHIGAN, A CORPORATION OF MICHIGAN WEATHER srmr Application filed J'une-22, 1929. Serial No. 372,959 This invention relates to weatherstrips and the object of the invention is to provide a Weatherstrip for a swinging wood casement or door and arranged to seal the outer face of the door or casement as well as the edge thereof. A further object of the invention is to provide a spring metal weather strip adapted tosea-ltwo faces of the closure member,one seal being a sliding contact and the other seal being a pressure contact. A further object of the invention is to provide a spring metal Weatherstrip bent at a right angle and having two inwardly extendmg gage by the edge and face respectively of the closure member. These objects and the several novel features of the invention fully described and claimed and the preferredrform'of construction by which these 1 objects are attained is shown in the accompanying drawings in which-'- Fig. 1 is an elevation of a swinging casement with which the Weatherstrip is used. Fig. 2 is an enlarged section through the window frame showing the Weatherstrip mounted therein. Fig. 3 is a similar section showing the swinging casement in relation to the weatherstrip and window frame. Fig. 4 is a perspective view of a portion of the Weatherstrip. f Fig. 5 is a section showing an alternative form of the ,weatherstrip in relation to the swinging casement and frame. Fig. 6 is a section showing another-alternative form of the Weatherstrip in relationto the window frame. Fig. 7 is a section showing the swinging casement in operative relation with the lzrvea'itherstrip and window frame shown in Fig. 8 is a section through another alternative form of Weatherstrip as utilized with an alternative form of window frame. Fi 9 is a similar view showing the closure memer in relative relation therewith. Fig; 10 is a section showing another alternative form of Weatherstrip. s ring metal flangesadaptedtobeenare hereinafter more- The principle of operation throughout the various alternative forms pf Weatherstrip s the same in that the weatherstrips each seal the "edge and face of'the swinging closure member. In Figs. 2, 3 and 4 the Weatherstrip comprises a flatspring metal base portion 1 having a flange 2 extending therefrom at a right angle and this flange 2' engages against the shoulder 3 formed in the window frame. At the outer edge of the base/portion is return bentv upon itself to form a portlon through which securing nails 4 may be driven and this return bent portion terminates in an angularly extending spring metal flange 5 which may be provided with a hemmed terminal edge 6 if desired. The flange 2 is provided with a bead 7 rolled therein from which the flange 8 extends at an angle toward the flange iand this flange 8 may be provided with; a hbmmed or return bent terminal edge 9 if desired. As the swinging casement is swung to the closed position, the edge 10 thereof rides in contact with the flange 5 of the Weatherstrip thus depressing this flange and sealing the case-- mentat the edge while the face 11 of the casement engages the spring metal flange 8 and compresses it as shown in Fig. 3 thus also sealing the face of the casing. By this arrangement the easement is sealed at two points against the weather. It "will be noted from Fig. 3 that the head 7. extends to the outside of the flange 2. In Fig. 5 an alternative-form is shown in Whlgll a bead 12 is formed in the metal on the inside of the flange 2 and a flange 13 is provided. extending upwardly therefrom into contact with't-he face of the casing. In this view 1t will be noted that the face of the casing contacts the head 12 as well as the spring metal flange 13 and thus the face of. the easement is sealed at two points. An alternative form of the Weatherstrip is shown in Figs. 6 and 7- in which the flange 2 is provided with an enlarged bead llrolled therein and this bead is provided with an angularly extending spring metal flange 15 which extends intocontact with the face 16 of the window frame. When the easement is swung into the frame tween the casing and frame. 1 leakage between the casement and the bead 14 while the easement is also additionally sealed by the spring metal flange 5. As shown in Figs. 8 and 9 windows and frames are-sometimes made with offset shoulders which inter-engage as shown'in Fig. 9 when the easement is swung into closed posit-ion in the frame. a Weatherstrip is provided as shown in Fig. 8 having a base portion 1 and return bent flange 5 and the securing nails 4 and this base portion 1 is provided with a flange 17 engaging against the face of the window frame 18 and provided with a retur-n bent portion 3 19 through which additional securing nails 20 are driven into the window frame 18. The return bent portion 19 extends outwardly and is provided with a bead 21 rolled in the outer edge thereof from which a spring metal flange 22extends, as shown in Fig. 8. This bead 21 and flange 22 are ilmllal to the bead 12 and flange 13 shown in i 5. FVhen the easement 23 is swung to the .closed position, as shown in Fi 9, the edge of the casement compresses the ange 5 while the face 24 of the easement compresses the flange 22 and engages the head 21 thus sealmg the casement at two points on its face and at a single point on its edge. If desired the head 21 and flange 22 maybe replaced by the head 7 and the flange 8'shown in Figs. 2, 3 and ff. In this form the Weatherstrip is substantially T'shaped and entirely covers the joint between the casement and frame and prevents leakage through the space be- In Fig. 10 an alternative form of the weath- For this construction tion, its utilit and mode of operation, what I claim and esire to secure by Letters Patent of the United States is- 1. In a Weatherstrip, a base member formed of spring metal and having a flange extending at a right angle thereto, a bead rolled into the outer edge of the said flange and having an integral spring metal flange extending toward the base member, the edge of the base member opposite the right angle flange being return bent to provide a spring an angle greater than a right angle one to the other with the free edges in adjacent relation. 3. In a weather strip for introduction between a frame and a hinged sash, said frame having a surface parallel with the peripheral edge of the sash and a surface parallel wlth the side face of the sash, a spring metal strip having a base consisting of a portion attachable to the frame and fitting each of the said surfaces thereof, the opposite edges of the strip being return-bent toward the respect1ve base portions and normally lying at an angle thereto with the free edges in adjacent spaced relation providing respectively for sliding contact with the respective peripheral edge and side face of the sash. In testimony whereof I sign this specification. ROBERT M. BURNS. erstrip is shown in which the basemember I i 1 is provided with a return bent flange 25 and thespring metal flange 5 is'a separate piece and is slipped beneath the return bent flange 25 and the nails 4; are driven through the return bent flange 25 and spring metal flange 5 to secure the device to the Window frame. In all other respects .this form is the same as that shown in Fig. 2. From the foregoing description it becomes evident that the device is very simple and efiicient in operation, will provide a double seal for hinged casement and doors,-will rovide a resilient stop for the casement or oor and provides a devlce which accomplishes the objects described.
