WINDOW PANE FASTENING STRIP Filed May 11, 1933 INVENTOR A/vro/v fiezz/A/a/w.

Patented June 26, 1934 WINDOW PANE FASTENING STRIP Anton Brezinski, Perth Amboy, N. J. Application May 11,v 1933, Serial No. 670,593

4 Claims.

This invention relates to window pane fastening strips and is" an improvement over the construction set forth in my United States Letters Patent No. 1,918,797, dated July 18-, 1933.

In the above mentioned Letters Patent, I provide a metallic ductile strip inlieu of putty for securing the glass pane in a window sash, and which includes pointed ribs adapted to flatten against the glass pane to seal the joint between the pane and the strip. Due to contraction of the strip under varying degrees of climatic temperatures, the sealed joints may become defective and permit of water entering the same, and the possibility of the water and air entering upon the inside of the sash. Therefore, the main object of this invention is to correct this defect by employing a joint which will compensate for the contraction of the retaining strip and maintain a seal at all times and under varying degrees of temperature.

Another object of the invention resides in a metallic window pane retaining strip having a yieldable sealing member mounted therein, and normally projecting beyond that face of the strip in which it is set, the material being such as to permit the same to be compressed tolie flush with the said face when the strip is applied in true position, and expand outwardly to compensate for any movement of the strip in a direction away from the joint to maintain a sealed joint between the parts.

A further object of the invention is to provide a window pane retaining strip which is simple and inexpensive of construction, and easy to apply to a window sash by one unskilled in the art of a glazer.

With these and other objects in View, the ill-- vention resides in the certain novel construction, combination and arrangement of parts, the essen tial features of which are hereinafter fully de-- scribed, are particularly pointed out in the appended claims, and are illustrated in the accompanying drawing, in which:

Figure l is a fragmentary sectional perspective view of a Window sash with the invention in use thereon.

Figure 2 is a vertical sectional view on the line 2--2 of Figure 1.

Figure 3 is a view similar to Figure 2 but showing the retaining strip about to be secured in position.

Figure 4 is a sectional perspective view of the retaining strip with the sealing element separated therefrom.

Figures 5, 6, 7 and 8 are detail vertical transverse sectional' views illustrating various modifications of the invention.

Referring to the drawing by reference characters, the numeral 10 designates my improved window pane retaining strip which is substantial-1y triangular in cross section and constructed. of a relatively soft malleable metal such as lead. The face 11 of the strip 10 constitutes the base of the strip whereas the adjacent right-angularly disposed face 12 constitutes a sealing surface for engagement with the glass pane to be secured in position. The base face 11 is provided with one or more pointed ribs 13 which extend longitudinally of the strip while channels 14 are disposed on opposite sides of the rib.

Formed in the face 12 and extending longitudinally of the strip is a channel 15 which is arcuate shape in cross section and slightly greater than one half of a circle. Seated within the recess 15 is a tubular shaped sealing element 16 preferably constructed of rubber and which when inserted into the recess, the same is retained by the walls thereof. By reference to Figure 3 of the drawing, it will be seen that a portion of the sealing element 16 projects beyond the face 12 of the retaining strip 10 for a purpose to be presently explained.

The face or surface 17 of the strip is flat and provided with spaced openings 18 which lead fromthe surface through the strip at an angle and open. onto the base face ll.

In order to illustrate the use of the invention, the strip 10 is shown associated with an ordinary type of window sash frame A, the same being provided with a rabbet B in which the edge of a glass window pane C fits. Instead of filling the rabbet with putty as is the present custom, a length of retaining strip 10 is cut to fit each side of the sash frame. The ends of the strip may be beveled so as to form tight joints at the corners of the frame and in the event that a strip should be cut a length shorter than that intended, the operator may manually pull upon the ends of the strip and lengthen the same to the desired length, the element 1-5 stretching during the pulling out" of the strip. This lengthening of the strip is made possible due to the nature of the material from which the strip is formed, and assuming that the strip is molded in the shape shown the lengthening of the same will in no way distort the cross sectional configuration thereof. When the strip is of the proper length, it is inserted into the rabbet B with the base surface 11 facing the bottom of the rabbet and the surface 12 facing the outer side of the window pane C and with the resilient yieldable sealing element 16 bearing against the glass pane as clearly shown in Figure 3 of the drawing. The operator then inserts nails or like fastening elements 19 through the open ings 18 in the strip and proceeds to drive the nails home into the sash frame. When the nails are driven home, the pounding applied by the hammer will cause the face 12 to tightly engage against the outer side of the glass pane C, the projecting portion of the sealing element 15 being compressed so as to lie flush with the face 12 as shown in Figure 2 of the drawing. During the fastening of the strip in position, the pointed rib 13 has a tendency to flatten out and become slightly embedded in the sash frame A to seal the base of the strip with the bottom of the rabbet B.

Assuming that the strip is fastened in the manner shown in Figure 2, it will be seen that by reason of the soft metal from which the strip is formed, the face 12 will conform to the surface of the glass C which it engages to produce a seal between the strip and the glass. In the event of contraction of the strip due to climatic temperature changes, it is possible that a space may occur between the surface 12 of the strip and the glass pane C. In such event, the compressed sealing element 15 will expand and maintain the watertight seal between the strip and the glass. Thus it will be seen that a seal is maintained between the strip and the glass at all times and under various degrees of temperature changes.

In Figures 5 to 8 inclusive, I have illustrated several modifications, and the same reference characters hereinbefore mentioned designate like parts in these figures of the drawing.

In Figure 5 I provide a recess in the face 12 as shown in the preferred embodiment of the invention, and I also provide a recess 15' in the base face 11. Identical resilient compressible elements 16 and 16' are respectively seated in the recesses or

channels

15 and 15 and the function is identical to that of the preceding form, but instead of only maintaining the seal joint between the strip and the glass pane, this construction also maintains a seal joint between the strip and the bottom wall of the rabbet provided in the window sash frame. A sealing rib 20 is provided in this form and has a groove 21 provided in the strip to one side of the rib.

In Figure 6 of the drawing, instead of providing an arcuate shaped channel in the strip 10, I provide tenon shaped channel which receives a yieldable resilient solid rubber sealing element 22, which normally projects beyond the face 12 but is compressible within the recess when the strip is in an applied position.

In Figure of the drawing, the

faces

11 and 12 of the strip 10 are provided with two sets of tenon shaped channels 21 which receive solid yieldable resilient sealing elements 22'. This construction provides a double auxiliary seal between the two sealing faces of the strip 10 and the parts which they respectively engage.

In Figure 8, the strip 10 is provided with a recess or channel 23 at the corner of the meeting faces 12 and 11, and seated in the recess is a solid rubber resilient sealing element 24. This element 24 sealingly engages the glass pane C and the bottom of the rabbet B.

While I have shown several embodiments of my invention, it will be appreciated that in all forms, the sealing strip is provided with one or more recesses or channels for receiving the yieldable resiiient sealing element in the form of a rubber strip, a portion of which normally projects beyond the plane of the sealing face or faces of the retaining strip. I prefer to use rubber in preference to felt and other materials due to the non-absorbent qualities of rubber. It will be seen that if felt or some other absorbent material were used in place of the rubber, the same would eventually become saturated with moisture or water which in turn would seep through the joint between the retaining strip and the glass pane.

Although several practical embodiments of my invention have been shown and described, it will be understood that such other changes in construction may be resorted to as come within the scope of the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

1. A window pane fastener comprising a strip of triangular shape in cross section, a recess provided in one of the faces of said strip and extending lengthwise thereof, and a yieldable sealing element seated in said recess and retained therein by the walls thereof, said element normally projecting beyond the adjacent face of said strip but compressible to a position within said recess to ie flush with said face.

2. A window pane fastening device comprising a strip of triangular shape in cross section, a recess provided in one of the faces of said strip and extending lengthwise thereof, and a tubular rubber sealing element seated in said recess and retained. therein by the walls thereof, said element normally projecting beyond the adjacent face of said strip but compressible to a position within said recess to lie flush with said face.

3. A window pane fastening device comprising a strip having two angularly disposed faces, a recess provided in one of the faces of said strip and extending lengthwise thereof, and a solid rubber sealing element seated in said recess and retained therein by the walls thereof, said element normally projecting beyond the adjacent face of said strip but compressible to a position within said recess to lie flush with said face.
