WILLIAM N BOOTH r l l ,y .ATT EYS Patented Aug. 22, 1939 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to movable and removable protective closures, of a supplemental character, for windows, doorways and other openings of buildings.

It is common practice, when a house or other building is to remain unused for a considerable Vperiod of time to apply some form of protective covering over all openings, especially those which are glazed. A common expedient is simply to nail boards over such openings, although these not only present an unsightly appearance, but to some extent permanently deface the building because of the nail holes which are formed.

Itis often desirable to arrange for airing such a temporarily closed building at suitable intervals, which is of course both troublesome and a cause of further disgurement of the building, if boards must be removed and replaced.

The present invention aims to provide means, especially adaptedr for use with steel sash, possessing all of the advantages of previously known supplementary closures of the character indicated, adaptedto protect the glass and the contents of the building and shield furnishings against the fading eiects of sunlight, of stronger and more secure character than previously known rprotecting means, and which is Weather, vermin and dirt proof, irremovable with ordinary tools when .locked in place, yet presents a much neater appearance. l

A further object is the provision of such protective covering means which is movable with the sash or frame by which it is carried, so that Windows may easily be opened (although only from the inside), as for airing, without removing or disturbing the protecting means.

Another important object of the invention is the provision of such supplemental protecting means for steel sash which may be readily applied and removed when the sash is open, but is securely held in place and irremovable when the window is locked.

(Cl. 18S-79) applied position, and being also shown in another dotted line position removed from the Window but aligned therewith and ready to be slid thereover.

Figure 2 is a perspective view of ythe rear face of the protecting cover element, removed from the window.

Figure 3 is a horizontal sectional view of the sash and protecting cover, taken substantially on the line 3-3 of Figure 1 and looking in the direction of the arrows, showing the cover slid over the window but not locked in place.

Figure 4 is similar view showing both the pro-- tecting device and window in their locked and closed positions of use, and

Figure 5 is a vertical sectional View, partly l5 broken away, taken substantially on the line 5-5 of Figure 1, looking in the direction of the arrows.

Referring now to the drawings, reference character Ill designates a window frame adapted to be set in a easement (unshown) or supported in any suitable manner. The window frame carries a swing sash frame I2, which is shown as operable rby a hand crank I5 and adapted to be secured tightly in closed position by locking means I'I'. These portions, as well as the glazing, muntins, and other structural features of the sash itself may of course be varied as desired and are intended `to be represented only diagrammatically, the present invention concerning itself with the protecting means rather than the window construction.

T'he swinging sash I2 is provided with an outwardly extending marginal flange I4 which, when the window is closed and locked, is tightly lclamped against the face of the frame member II). The hinging means is shown as comprising a pair of outwardlyv projecting pivotally connected arms I8-I9, the former carried by the frame and the latter by the sash. A bracket portion I 6, secured to the face of the sash in 40 the hinged corners, serves to fasten the sash to the hinge arms I9.

The protecting element comprises a sheet metal cover member 20 having all four of its edges marginally over-bent to embrace and retain it upon the ilange I4 of the sash. The top and bot,- tom over-bent retaining flanges of the cover member are designated ZI, and as best appear in Figure 5, these are so spaced as to fit snugly but slidably over the sash flange portions. Retaining portions I4 terminate short of the hinged edge of the cover, .and at the upper and lower hinged corne-rs unflanged embossed sections 25 are formed to provide clearance for the hinge brackets I 6. The hooked retaining flange 22 which 55 extends along that edge of the cover which overlies the hinged edge of the sash, also terminates short of the embossed areas, as shown in Figure 2. The similarly hooked retaining flange portion 23, for the free edge of the swinging sash, overlies the sash flange to a somewhat greater eX- tent, for a purpose which will presently appear.

The cover is placed upon the window by fitting the cover flanges 2l over the sash flange I4 (top and bottom, with the window positioned as shown in the drawings), and sliding the cover from the free edge of the swinging window entirely thereover and until the retaining portion 22 lies beyond and is free of the hinged edge, as shown in Figure 3. For this purpose, the width of the cover member will be seen to exceed the width of the window suiciently to allow the portion 22 to so clear the hinged edge when the cover is slid over the window as far as it will go. The overhanging portion 23 which embraces the free edge, however, is of such length that when the cover is again slid outwardly in a direction away from the hinged edge, to engage the portion 22 behind flange I4 along the hinged edge of the sash, the flanged portion 23 remains in overangaged relation with the free edge of the sash, as shown in Figure 4 (in which View the window is also shown closed and locked).

A certain amount of exibility is provided by the fact that the top and bottom overbent holding and slide flanges 2| do not extend entirely to the hinged edge. The cover material is thereby able to bend somewhat about an axis parallel to the flange 22 and located at approximately the rear ends o-f the flanges 2|, during application and removal of the cover, allowing ange 22 to freely snap over the hinged edge of the sash. When the cover is moved in the fully applied position in which it is shown in Figure 4, and the window is closed and pulled tight by the locking means, the flanges 2l, 22, 23 are tightly clamped between the sash and the frame, preventing removal of the cover.

The only requisite to convenient application of my improved covering means will be seen to be a Window (or door) having marginal portions over which the retaining flanges may be iitted before closure thereof. The retaining flanges, upon one or more sides, might of course be discontinuous, and in the form of lingers, although I prefer merely to overbend the edges of the material in the manner shown. Creasing the cover material slightly, in the manner indicated at 33, somewhat stiiens it as well as imparting a finished appearance, which may be heightened further by painting or finishing the covers to match the material or trim of the building. The windows may be opened and closed as many times as desired without danger of dislodging the installed covers, exactly as if they were not present, and it will also be recognized that the covers may be most economically produced of sheet metal, galvanized iron or the like.

The locking means l1 should of course be arranged to draw and hold the window tightly inward against the face of the frame and the interposed retaining flanges of the cover.

While it will be apparent that the illustrated embodiment of my invention herein disclosed is well calculated to adequately fulfill the objects and advantages primarily stated, itis to be understood that the invention is susceptible to variation, modication and change within the spirit and scope of the subjoined claims.

What I claim is:

1. In combination with a substantially rectangular swingable closure having opposed outwardly extending marginal flange portions upon all four edges, a frame with which said closure ,is swingably associated, and locking means for one thereof, and the nearest edge of the overbent portion of the other is Igreater' than the extreme distance between the outside edges of the corresponding flanges of the closure overengaged thereby, the distance between the inturned edges of the second-named retaining means being less than the distance between the outside edges of the mating closure anges overengaged thereby, whereby two of said opposed retaining portions are engageable with the ang-es only by sliding thereover, while at least one of said retaining portions is movable perpendicularly over the edge of its ange portion before being slid into engagement therewith.

2. In combination with a substantially rectangular swingable closure having opposed outwardly extending marginal flange portions upon all four edges, a frame with which said closure is swing-ably associated, and locking means for the closure arranged to draw and hold said flanged portions tightly against said frame, a supplementary cover member having overbent retaining portions adapted to overengage said flanges, the overbent retaining portions upon two op-posite sides of said cover member forming grooves slidably iitting over said i'ianges and irremovable therefrom perpendicularly of the plane of the closure, the other two sides of the cover member being provided with similarly overbent retaining portions, the distance between the inner edges of said last mentioned retaining portions being lessl than the distance between the outer edges of the mating flanges, and the distance between the inner edge of one of said retaining portions and the bottom of the groove formed by the opposite retaining portion being greater than said distance between the outer edges `of the flanges, at least a portion of said cover member being iiexible abo-ut an axis parallel to sai last mentioned retaining portions.
