3 Claims.

The principal objects of this invention are to provide a simple but efficient double glazing attachment which may be easily applied without alteration in the standard sash formation and which will be tightly held in place in a manner which will permit the ready removal or replacement thereof.

T'he principal features of the invention reside in the novel construction of the double glazing frame and a special resilient retaining means for securement to the sash whereby the double glazing frame is resiliently urged into snug sealing engagement with the sash but is capable of ready removal by flexing of the resilient retaining means.

In the drawing Figure 1 is a fragmentary cross section through a portion of a sash showing a preferred form of the present invention applied thereto.

Figure 2 is a View similar to Figure 1 showing a modification of the present invention.

Figure 3 is a fragmentary corner view of a double glazing frame such as shown in Figures l and 2, the frame portion being broken away to disclose the underlying resilient retaining means.

Many forms of structures have been devised in connection with double glazing of windows but these in many cases are of a complicated nature or require sashes of special cross section or the provision of recesses.

The present invention has been devised to eliminate these objections and to enable the mounting of a double glazing frame directly on any standard window sash, and in the preferred form of the invention illustrated in Figures 1 and 3 a special retaining. member I is provided which preferably comprises a strip of resilient metal of angle shaped cross section having a ange 2 adapted to flatly overlie the inner face 3 of the sash 4 with or without a sealing strip 5 therebetween.

The other flange portion 5 extends perpendicular to the face 3 of the sash and is here shown provided with an inwardly rolled or beaded extremity 1.

The strips I are preferably placed in a rectangular arrangement presenting mitred corner joints 8 and with the inner edge of the flange 5 in register with an edge 9 of the sash to provide for accurate positioning.

A double glazing frame I0 is shown in Figure l as formed of a strip of metal, the edge portions of which are doubled back upon themselves and turned laterally to form a channel II within which the edges of the secondary glass I2 are sealed. l

The intermediate portion 'of the stripis bent to provide a tapering or bevelled area I3, which, When the frame is pressed into position, will en'- gage the beaded portion 'I of the spring-retaining means and spread these su'iciently to allow the shoulder portion I4 to pass therebeyond. The portion of the strip on the other side of the shoulder I4 is channeled to provide a sloping wedge surface I5 which is adapted to co-operate with the beaded portion 'l of the retaining means so that the resilient inward pressure of the latter on the sloping wedge surfaces will exert an inward pressure on the frame I0 tending to urge the same into snug non-rattling relation to the sash, and a sealing strip of felt or the like I6 may be arranged between the inner portion of the frame I0 and the flange 5 to be retained under sealing compression by the resilient wedging engagement referred to.

The frame-forming strip is ared outwardly to overhang the beaded portion] and4 to extend beyond the flange 6 and the arrangement is such that a space I'I will be provided between the overhanging portion and the beaded portion 'I as illustrated in Figure 1. This provides an advantageous arrangement for the insertion of a prying tool I8. With this arrangement a gentle pull on the inserted member I8 will exert an effective prying action on the frame while a constricting force will be applied to the beaded portion 'I as well as a spreading action on the flanges 6, providing for the very easy removal of the frame.

In the modification shown in Figure 2 the frame I0 is shown formed of a strip of extruded metal having the tapered surface I3 and wedging surface I 5 arranged to cooperate with the resilient beaded portion 'I' as defined in connection with the corresponding surfaces I3 and I5 of Figure 1.

What we claim as our invention is:

1. The combination with a standard sashl having its innermost surface disposed in a iiat plane, of a double glazing frame to be applied fiat over said innermost sash surface and formed with a sloping Wedging surface about the perimeter, and resilient retaining members formed of strips of spring metal of substantial rightangular flanged form disposed in a rectangular frame formation and having one flange portion secured at to the said innermost sash surface in such relation as to be overlapped and concealed by the said frame and having the other ange portion extending substantially perpendicular to said innermost plane forming a resilient frame continuously embracing the perimeter of said double glazing frame in resilient pressure-holding relation in contact with said sloping surfaces.

2. The combination with a standard sash having its innermost surface disposed in a flat plane, of a double glazing frame for application over said innermost sash surface, said frame being formed with a wedging surface extending about the perimeter, and strips of spring metal having ange portions for attachment to the said innermost surface of the sash in underlying relation to the said frame and having inturned portions for resilient wedging engagement with said wedge surfaces, said frame presenting rigid flange portions overhanging and spaced from the inturned portions of said spring strips, and adapted to form a space for the reception of a frame-removing instrument whereby a prying action may be exerted between said overhanging anges and the inturned portions of said spring strips to remove the frame without marring of the inner surface of the sash.

3. The combination with a standard sash having its innermost surface disposed in a flat plane, of a double glazing frame formed to overlap said innermost plane surface of the sash and presenting a locking groove about the per imeter spaced inwardly from said innermost sash surface, and spring-retaining members secured to the sash and having beaded portions spaced inwardly beyond said innermost sash slu'face a distance slightly less than the inward spacing of said frame groove to engage the outermost wall of said groove in pronounced wedging action to thereby retain the frame in pressure engagement with the sash, said beaded portions being of resilient form confined within the plane of the double glazing frame and return-bent toward thelatter and outwardly to substantial circular form with the free end portion of the resilient bead presenting the major resilient wedging engagement with the groove wall whereby to facilitate placing and removal of the double glazing frame. y
