2 Claims. (Cl. 20-55) 4 This invention relates to storm windows and to means for fastening such windows in position.

The present types of storm windows, if they are of the conventional woodenframed type, are both expensive to acquire and heavy to put up and take down, while the metalframed, e.g. aluminum, storm windows, though extremely convenient, are priced beyond the reach of many.

We have devised a storm window which is very cheaply and easily made and oan in fact be made and erected by any householder possessed of a slight degree of manual dexterity and a scintilla of ambition to doit-himself. Furthermore, since the storm windows of our invention are only a trace heavier than the glass empldyed therein, and since our fastening means only calls for the driving of two screws, the novel storm windows can be simply and quickly put up and taken down.

The storm window of the invention comprises a sheet of glass which is of the same shape as, but is of slightly greater dimensions than, the opening which is to be covered, resilient, easily compressible material mounted at least upon the inner face of said sheet adjacent the periphery thereof and extending substantially completely around said sheet so as to provide a frame therefor, and fastening means secured to said sheet and securable to the frame of the opening which is to be covered.

The fastening means of the invention may be generally defined as a Ushaped member adapted to be press- Ifitted upon an edge of the sheet of glass and anchoring means detachably connectable to the U-shaped member.

Thus, if the householder wishes to make his ovin storm windows, he need only order suitably sized sheets from a glazier, adhesively secure strips of resilient, compressible material around the edges of the sheet, and slip two or more (depending on the size of the window) of the U-shaped members over the edges of the sheet of glass. The storm window is now complete and ready to be fixed in position by connecting the U-shaped members to the anchoring means.

In drawings illustrating two embodiments of the invention:

Figure 1 is a perspective view showing part of a storm window according to the invention, with the window about to be mounted upon the frame et a conventional window;

Figure 2 is a vertical cross-section through the centre of the fastening means, showing the window of Figure 1 mounted in position upon a window frame, and

Figure 3 is a cross-section view similar to that of Figure 2 but showing a modification wherein the strip of compressible material is applied after the U-shaped member has been press-fitted upon the edge of the sheet of glass.

Considerng Figures 1 and 2 in detail, first, reference character A represents the rectangular frame of a window opening provided with any conventional window as indicated at B, whfle C represents a sheet of window glass 2,975,491 Patented Mar. 21, 1961 which is to be employed to make a storm window for supplementing window B in the closing of the window opening having the frame A. The window glass sheet C should be of the same shape as, but of somewhat greater dimensions than, the inner penphery of the window fname A so that the sheet can be positioned to overlap the outer face D for about one-half au inch (measured outwardly from the inner periphery of the opening at the outer face of the frame) when laid thereagainst in alignment with the opening.

Each edge of the sheet C is provided with a strip of resilient, easily compressible material 10 which is folded to assume a U formation in which it embraces the edges of the sheet, as best seen in Figure 1. The strips 10 are each adhesively secured to the edge which they have been folded to embrace. As the strips 10, we preferably employ commercially available strips of synthetic rubberlike foam such as, for example, polyurethane foam, which strips are coated along one of their sides with a pressure-sensitive adhesive. Such strips are sold with a protective backing strip on the adhesively coated side, which backing strip need only be peeled ofl in order to ready the strip itself for application to a sheet of glass in the manner shown in Figure 1.

Once the strips 10 have been applied along each edge of the sheet C, the storm windows are simply completed by press-fitting over the edges thereof at least two U- shaped members 11 which are designed to tightly compress the portions of the strips 10 which are straddled when the Ushaped members are mounted on the edges of the sheet. For small sheets of glass C We employ two such U-shaped members 11 mounted on opposite edges of the sheet, at points substantially mid-way therealong, but for larger sheets a suitably greater number of members 11 would be employed. Attached to each member 11 is a tension spring 12, to the unattached end of which is secured a cross-bar or pin 13 at a point intermediate the ends of the latter.

Small plates 14 are secured to the framework A by means of screws 15. The plates 14 carry two hooked portions 16 adapted to receive and retain the cross-bar or pin 13. Once the plates 14 have been mounted in place it is only necessary to stretch the springs 12 and insert the bars 13 within the hooked portions 16 extending from the plates 14. Once this has been done the storm window will be mounted in position; with the window drawn by the springs 12 flushly against the outer face D of the window frame; and with the strips 11 forming an efective seal against the elements since, being easily compressible and resilient, they will be compressed by any protrusions in the face of the frame but will fill in any somewhat dished or depressed regions of the face D which they may overlap.

The embodiment illustrated in Figure 3 is generally similar to the embodiment shown in Figures 1 and 2. However, in the case of Figure 2, a U-shaped member 11a is provided which is designed to be press-fitted over the edge of the sheet C before the strips 10 are mounted thereon. Therefore the Ushaped members 1111 should be closely complementary in shape to the edges of the sheet of glass C. We prefer to provide the edges of the sheet C, wherever one of the elements 11a is to be mounted, with a layer of adhesive tape 17 before pressfitting the members 11a into position. Having applied the tape 17 and mounted the members 11a in position, the strips 10 are then foldd t0 embrace the edges of the sheet C and are adhesively secured in their -edge enveloping positions along each edge of the sheet. The window shown inFigure 3 is mounted in exactly the same manner as the window shown in Figures 1 and 2, i.e. with the aid of springs 12, pins l3, plates 14, screws 15 and hooked portions 16 carried by the plates 14.

What we daim as our invention is:

1. A storm window assembly compising, in combination, a window opening, a window frame encompassing said window opening, 21 sheet of glass covering said window opening, said sheet of glass having substntiadly the same shape as but being somewhat larger than said window opening whereby said sheet of glass extends on all sides to overlap said window frame to a sufiicient degree to ensure safe seating of said sheet of glass; resilient, easily compressible material mounted upon at least the inner face of and extending perpherially completely around said sheet of glass as to provide a frame therefor; a plurality of U-shaped members spaced around the periphery of said sheet of glass and straddling the edges thereof, the portions of said compressible materal whichnnderfie said U-shaped members being compressed; a plurality et plates secured to said window frame, a

4 tension spring attached to each of said U-shaped members, and means for detachably connecting said springs to said plates.

2. A storm window as defined in claim 1, wherein said means for detachably connecting said springs to said plates comprises a bar connected to the free end of each of said springs and hooked elements extending from said plates to receive and retain said bars.
