Application August 20, 1951, Serial No. 242,599

1 Claim. 1

This invention relates to fasteners for window panes or the like and has for an object to provide a strip fastener which is easy to handle and apply and which effects a tight permanent seal. The strip is primarily usable to replace putty for securing window panes in sash.

Various other objects and advantages will be apparent as the nature of the invention is more fully disclosed.

Although the novel features which are characteristic of this invention are pointed out in the claim, the nature of the invention will be better understood by referring to the following description, taken in connection with the accompanying drawing in which a specific embodiment thereof has been shown for purposes of illustration.

In the drawing:

Fig. 1 is a front elevation of a window sash and pane embodying the present invention;

Fig. 2 is a transverse section on an enlarged scale taken on the line 2--2 of Fig. 1;

Fig. 3 is a section taken on the line 33 of Fig. 2;

Fig. 4 is a detail view of a fastening and sealing strip embodying the present invention; and

Fig. 5 is a detail view of the blank used in making the fastening and sealing strip.

In the various figures like parts are identified by like reference characters.

Referring to the drawing more in detail, the invention is shown as applied to a window comprising a sash ID in the form of a rectangle having top and bottom members II and I2 respectively and side members [3. The sash I0 is shown as mounted in a fixed frame I4 the details of which form no part of the present invention.

The sash I0 is shown in Fig. 2 as having a flat surface [8 defining an opening to receive a pane and having on the inside a flange 2| which may be milled in one piece with the sash or may constitute a separate piece secured to the sash as in the usual practice.

The pane 20 is seated against the flange 2| and secured by a fastening and sealing strip embodying the present invention. The strip '25 comprises a strip 26 of flexible sealing material such as rubber, natural or synthetic, which is waterproof, is resistant to the atmosphere, and which is capable of retaining its flexible sealing characteristics.

The sealing strip 26 is secured in a metal strip 21 which is bent into a U-shaped cross-section having inner and outer legs 28 and 29 respectively between which the sealing strip is clamped. The inner leg 28 is made shorter than the outer leg 29 so as to provide clearance for the pane 20. The sealing strip 26 extends beyond the end of the outer leg 29 a sufiicient distance to provide flexibility for conforming to the window pane 20. The metal strip 21 is made of a material which is resistant to atmospheric conditions, for example aluminum or stainless steel. For securing the same to the sash points 30 are struck out of the blank as indicated in Fig. 5 and are bent to extend about normal to the strip so as to be driven into the flat surface 18 of the sash I0 at an inclined angle, thereby firmly securing the strips 25 in place and preventing the row of points from splitting the edge of the sash.

In use, the pane 20 is placed against flange 2|, the strip 25 is cut to the proper lengths to fit each side of the pane, preferably with the ends 3| bevelled for a tight fit (Fig. 1). The strip is then pressed firmly against the pane and sash to cause the protruding portion of the sealing strip 26 to conform to the pane and the points 30 are driven into the sash with a hammer. The points thus serve to hold the strip 25 permanently in place. The strip may be painted if desired. The metal strip 21 is made from stock sufiiciently thick to provide rigid parts for securing and holding the strip in place.

If it becomes necessary to remove the pane 20, the strip 25 can be easily removed by inserting a tool and prying the same from the sash. Hence the strip is well adapted for use by home owners as no special skill is required in applying or removing the same. In addition much less time is required than in the case of putty or the like.

Although a specific embodiment has been shown and described for purposes of illustration it is to be understood that the invention may be applied to other uses and that changes and adaptations may be made therein as will be apparent to a person skilled in the art.

What is claimed is:

In a window having a sash and a pane, a sealing and fastening strip for securing said pane in said sash, comprising a strip of flexible sealing material and a metal fastening strip bent into a U-shaped cross-section to form inner and outer legs between which said flexible strip is clamped with the flexible strip extending beyond the end of said outer leg, said metal strip having fastening points struck out of the metal thereof at the base of said inner leg and projecting inwardly therefrom substantially normal to said inner leg to be driven into said sash at an angle to draw said strip into securing engagement with said pane, said outer leg being longer than said inner leg by an amount such that the free edges of said legs are about equally spaced from said pane when said strip is in sealing position.
