cAsEMENT SCREEN AND THE LIKE Filed Oct. 19. 1932 n mi.; AWMWMM Patented Dec. 19, 1933 UNITED STATES PATENT oFFlcE CASEMENT SCREEN AND THE LIKE Application October 19, 1932. Serial No. 638,617

7 Claims.

The invention relates to certain improvements in auxiliary closures, such as screens and storm sashes, for use in connection with easement windows, and has for its object to provide such closure devices with resilient sealing means to close the opening between the frame of the auxiliaryclosure and the easement frame and also between the easement frame and the easement sash.

The invention is illustrated in the ,accompanylo ing drawing, in which:-

Fig. l is a lateral sectional elevation of a typical easement window to which the invention has been applied.

Fig. 2 is an enlarged fragmentary front eleva-4 l tion.

Fig. 3 is a section on line 3 3 of Fig. 2.

Fig. 4 is a fragmentary section of a storm sash.

Referring to Figs. l to 3 of the drawing, 1 indicates a easement frame of conventional form 0 involving the usual Z bars of metal fashioned to t the opening in the wall of a building structure and 2 indicates the cooperating sash of the easement window, which is similarly formed of Z bar sections and is connected to the frame l by the usual hinges, not shown, to permit the sash to be swung to open -or closed position, .the sash being provided with the usual glass panel .3. It will be understood that the easement window construction is merely exemplary and, instead of the particular form shown, it may involve any of the usual forms now generally employed in building construction.

It is customary practice to provide easement windows with removable screens securedto the inner or outer face of the easement frame, de-

pending upon whether the easement sash swings inwardly or outwardly with respect to the frame. As shown in the drawing, the easement window is of the former type, namely, with an outwardly o swinging sash. Therefore, the screen is shown as secured to the inner or room face of the casement frame. It is also highly desirable, and frequently quite diffeult, to apply weather stripping or sealing means to easement windows for 5 the purpose of sealing the openings between the meeting portions of the easement frame and sash, when the latter is closed, to exclude air, moisture, dust and the like. Likewise, Vin many eases, it is found necessary or desirable to t easement 0 windows of this general character with removable storm sash, which serves the usual and intended purposes of such auxiliary closure devices in winter seasons or in cold climates.

As stated, the present invention involves the provision of an auxiliary closure, either in the form of a removable screen or a removable storm sash, which may be readily applied to and removed from operative relation with respect to the easement window and which comprises, in its component structure, a sealing strip so diss0 posed as to effectively close the cracks or openings between the auxiliary closure and the frame of the easement window and also similar cracks or openings between the easement frame and the sash, when the latter is in closed position.

In its preferred form, when the auxiliary closure is a screen, as illustrated in Figs. 1 to 3, it comprises a frame which conforms generally to the shape of the easement frame l, so as to partly overlie the abutting face of the easement 70 frame adjacent the inner edge of the latter. The frame 10 is preferably made of metallic channel sections separated by longitudinalribs, the outer channel 1l being adapted to receive the sealing or packing strip and the inner channel 12 adapted to receive the turned edges of the woven wire screen material 13, which is locked securely in the frame by the usual keys or splines 14 of spring metal or the like. The sealing strip 15 may be of any suitable resilient material, such as rubber, felt or the like, that may be readily forced into andheld securely in the groove or channel l1, which extends entirely around the frame 10. The said sealing strip is preferably preformed with a laterally projecting flange 16, which, as shown, overhangs the flange or rib dividing the channels 11 and 12, the ange also being of suflicient thickness to abut and be compressed against the inner face of the sash frame, when the sash is in closed position. As clearly =indicated in the drawing, the projecting portion of the resilient packing strip 15 is of such form, and dimensions as to cause it to be compressed against the face of the easement frame, against the inner edge of said easement frame and also against the inner face of the sash, in the rela- I tion indicated more particularly in Fig. 3, and, therefore, to constitute an eiective seal for the openings which normally exist between the screen frame and the easement frame and between the easement frame and the easement sash.

The screen may be secured in proper abutting relation with the face of the easement frame by any appropriate means, which will ,be effective in clamping the screen firmly against the casement frame with sufcient force to press the projeeting portions of thesealing strip 15 into engagement with the aforesaid surfaces of the casement frame and sash. A relatively simple but eif'ective means for securing the screen to the 110 casement frame comprises two or more Z-shaped supporting brackets 20 fastened to the lower rail of the casement frame, the outer leg of each bracket preferably being inclined outwardly and upwardly to afford a Wedging t with the lower rail of the screen frame. The stiles or side members of the screen frame and also the top rail, in the case of relatively large screens, are provided with lip-like extensions, such as 22, which may be spot Welded or otherwise secured to the screen frame', at proper intervals, and which are adapted to be engaged by the heads of bolts or threaded turn buttons, such as 23, secured to the face of the casement frame. These simple securing devices are effective in clamping the screen securely in position against the face of the casement frame and admit of the screen being applied to or removed from position expeditiously and without the need of special tools.

As hereinbefore stated, the invention is also applicable to storm sashes adapted to be applied as auxiliary closures to casement windows, such storm sashes to be employed alternatively with the screens, that is to say, when thescreens are removed at the end of the summer season, they may be immediately replaced by the storm sash for use throughout the late fall, winter and early spring. As illustrated in Fig. 4, the storm sash differs structurally from the screen only in the means for securing the glass 13' in the frame. As shown, the frame comprises metal sections 10 having one channel 11 substantially identical with the channel 11 in the screen frame and in which channel the same form of resilient packing strip is secured. In order, however, to secure the glass pane or panes in the frame, the inner portions of the frame members are provided Wth stepped iianges 14' and 14 adapted to receive the cement or other medium by means of which the glass is fixed in the frame. As shown, the shorter ange 14 is adapted to receive the flanged edge of a suitable channel-like ,nishing strip 17, which surrounds and protects the portions of the cement which would be exposed otherwise.

What I claim is:

1. An auxiliary closure for casement windows, comprising a frame adapted to be secured in overlapping relation to a face of the casement frame, and a strip of resilient material carried by, extending around and projecting from the face of said frame that abuts the casement frame to effect a seal between the frame and the casement frame and between the latter and the sash.

-2. An auxiliary device as set forth in claim 1, in which the sealing strip is secured in a groove in the closure frame.

3. An auxiliary closure for casement windows, comprising a frame adapted to be secured in overlapping relation to the casement frame, said frame having a groove extending around the .face thereof that abuts the casement frame, and a sealing strip secured in and projecting from said groove to seal thel openings between the frame and the casement frame and between the latter and the sash.

4. An auxiliary closure for casement windows, comprising a frame adapted to be secured in overlapping relation to the casement frame, said frame having a groove extending around the face thereof that abuts the casement frame, and a sealing strip secured in and projecting from said groove and having a laterally projecting ange adapted to engage the inner marginal edge of the casement frame and the adjacent face of the sash.

5. An auxiliary closure for casement windows, comprising a frame of a size to partly overlap the casement frame and having a groove extending around the face thereof that abuts the casement frame which groove is partly overlapped by the inner e'dge of the casement frame, and a packing strip in said groove adapted to engage the face and inner edge of the casement frame and the inner face of the sash.

6. A screen for casement windows, comprising a frame formed of metal channel sections and adapted to partly overlap the casement frame, an'd a packing strip projecting from a channel in the screen frame so as to engage the adjacent face and inner edge of the casement frame and the .inner face of the sash.

7. An auxiliary closure for casement Windows, comprising a frame adapted to overlie one face of the casement frame and having a. resilient strip carried by and extending around the face that abuts the casement frame and so disposed as to -close the opening between said frame and the casement frame and the opening between the casement frameand sash.
