like.

An important object of this invention is to provide a new and improved fastener for retaining a pane of glass in a window frame or the like, wherein the fastener is adapted to be pressed into position for holding the pane of glass in the frame and is also releasable from such holding position for permitting the removal of the glass from the frame.

Another object of this invention is to provide a new and improved fastener for releasably retaining a pane of glass in a window frame or the like, wherein the fastener is formed with two legs which normally extend so as to form an acute angle therebetween; the legs being made of a resilient material which permits the legs to be spread apart so that the inherent resiliency of the material constantly urges said legs toward each other for retaining the pane of glass in the frame.

A further object of this invention is to provide a new and improved window construction, wherein a fastener serves to releasably hold the glass in the window frame, and wherein means are provided for positioning sealing material such as putty between the glass and the frame, such sealing material being readily accessible for removal or replacement when the glass is removed from the frame.

The construction designed to carry out the invention will be hereinafter described, together with other fea tures thereof.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings forming a part thereof, wherein an example of the invention is shown, and wherein:

Figure 1 is an elevation illustrating a portion of the .window glass construction of this invention.

Figure 2 is an isometric sectional view illustrating the improved window glass construction of this invention in the assembled position.

Figure 3 is an isometric sectional view illustrating the improved fastener of this invention.

Figure 4 is an isometric sectional view of a portion of the frame of the improved window construction of this invention.

In the drawings, the letter F designates a window frame or other frame which has a section or pane of glass G connected therewith by means of a fastener or retainer R (Figure 1). As will be explained in detail, the fastener or retainer R is so constructed and so positioned with respect to the frame F and the glass G that it is merely pressed into retaining position and can be readily released from such position when it is desired to remove the glass G for replacement or otherwise.

. Considering the invention more in detail, the particular frame F illustrated for use in the improved window construction of this invention is composed of a plurality of frame sections, each of which has an inclined or mitered end 10 (Figure 1) for abutment with a corresponding inclined end 10 of an adjacent frame section. The face 11 of each frame section lies in substantially the same plane as the pane or section of window glass G and, ordinarily, the faces 11 of each frame section would be disposed on the inside of the house or building so as to be visible to a person on the inside.

Side portions

12 and 14 are parallel to each other and perpendicular to the face portion 11. A longitudinal groove which is substantially circular in a cross section and which is identified by the numeral 15 forms a part of the side 14 of the frame section (Figure 2) and is provided for receiving a screw or other attaching means which extends from an adjacent frame section and therefore provides one means for attaching the frame sections of the frame F together, but such attaching means forms no part of the present invention, since any means for attaching the sections of the frame F together can be used.

The side 14 actually forms one side of the channel section of the frame which is disposed inwardly of the side 14 and includes a support portion 17 which is parallel to the side 14 and which is connected to the side 14 by a bottom portion 18. The support portion 17 is connected with and supports a flange 20 which is perpendicular to the support portion 17 and is coextensive therewith. The inner part of the flange 20 extends into the space or channel S which is formed between the side 14 and the support portion 17, and a longitudinal lip or shoulder 22 is provided on the flange 24), the purpose of which will be more evident hereinafter. The flange 20 is formed with a longitudinal recess 23 which is disposed between glass receiving strips 24 and 25. Such strips 24 and 25lie in the same plane and are for the purpose of receiving the outer surface of the pane of glass G (Figure 2). The recess 23 is filled with putty or other sealing material when assembling the glass G on the strips 24 and 25, whereby a fluid tight seal between the glass G and the frame F is provided.

The fastener or retainer R is formed in sections which correspond with the sections of the frame F and accordingly when the frame F is formed with four sections to make a square or rectangle, as is true in the usual case, the fastener R will likewise be formed in four sections each of which has an inclined end which is positioned adjacent a similar inclined end 40 on the adjacent section of the fastener R. A portion of one section of the fastener R is illustrated in Figures 2 and 3, with Figure 3 illustrating the section of the fastener R separate from the rest of the window construction of this invention and Figure 2 illustrating the fastener R in the assembled position for retaining the glass G connected to the frame F.

,The fastener R has a front leg 41 which is visible to a person on the inside of the house or building in which the window glass construction of this invention is positioned. A glass retaining leg 42 is connected to the front leg 41 and is coextensive in length with the leg 41. At the opposite end of the leg 4-2 from that end which is connected to the leg 4i, there is provided a gripping flange 45 which is adapted to be positioned below the longitudinal shoul er or lip 22 for retaining the glass G in position on the frame F, as will be explained more in detail.

Preferably, each section of the fastener R is formed with the legs 41 and 42, and the flange 45 in one piece by molding, extrusion or otherwise. The material of the fastener R is a plastic of the phenol formaldehyde type or vinyl resin type, or any other suitable material which is sufiiciently resilient to permit the spreading apart of the legs 41 and 42 while being sufliciently still so that the legs 41 and 42 are themselves not flexible to any appreciable extent. The legs 41 and 42 are molded or otherwise formed with the angle A therebetween which is preferably less than ninety degrees, i. e., an acute angle. The material .of which the fastener R is made is sufficiently resilient so that as the angle A is increased from its normal amount (Figure 3) and approaches a right angle by the spreading apart of the legs 41 and 42, the inherent resiliency of the material causes the legs 41 and 42 to be urged toward each other.

Such spreading of the legs 41 and 42 with respect to each other occurs when the fastener R is assembled (Figure 2) with the leg 42 extending downwardly into the channel S and the flange 45 below the shoulder 22. When the fastener R is in the assembled position, the inner surface 41a of the leg 41 is in contact with the inner surface 31 of the glass G and the angle A is enlarged so that the inner surface 42a is substantially parallel to the end 32 of the glass G. It will be noted that the outer surface 42b of the leg 42 is curved so that the lower end (Figure 2) of the leg 42 is of a reduced thickness in the vicinity of the flange 45 to permit the insertion of the leg 42' into the channel S. Similarly, with the curved surface 42!) of the leg 42, an upward force can be applied to the leg 41 for lifting same whereby the leg 42 is moved out of the channel S. Such lifting of the leg 41 can be accomplished by inserting a wedge shaped member such as a screw driver between the surface 31 of the glass G and the inner surface 410: of the leg 41.

The operation or use of the improved window glass construction and fastener therefor is believed evident from the foregoing description. Thus, when it is desired to assemble the window glass G in the frame F, putty or other sealing material is distributed in the putty groove 23 of each section of the frame F. Then, the glass G is positioned in contact with the strips 24 and 25. The putty or other sealing material in the grooves or recesses 23 provides a fluid-tight seal so that water, air and other elements of the weather are prevented from passing between the glass G and the frame F.

With the glass G in position on the frame F, the fastener R is pressed into its holding position. Although the sections, generally four in number, which together form the fastener R, can be inserted together during assembly thereof with the frame F and the glass G, preferably each straight section or side of the fastener R is separately positioned so that the adjacent inclined edges 40 are in contact or substantially in contact (Figure 1). The fastener R may thus be pressed into the channel S by the application of pressure thereto with the hands or, it may be desirable to use a roller or similar known apparatus for applying a moderate amount of pressure to the fastener R. The pressure is required because the angle A is less than the angle A which is formed after the legs 41 and 42 have spread apart during assembly. Thus, as the fastener R is forced downwardly into the groove S, the legs 41 and 42 are spread relative to each other so that there is a constant tendency for the leg 42 to move toward the glass G (to the left in Figure 2) which results in a frictional engagement of the flange 45 with the metallic flange 20 of the frame F. Such urging of the leg 42 toward the glass G during its insertion also serves to urge the flange 45 underneath the shoulder 22 when the fastener R has reached its lowered position with the surface 41a of the leg 41 in contact with the surface 31 of the glass G. At such time, the legs 41 and 42 are still maintained in a spread condition as compared to the original condition (Figure 3) so that the glass G is maintained in firm engagement with the surfaces 24 and 25 of the frame F and is locked or held against movement away from the frame F by reason of the flange 45 gripping below the shoulder 22.

When it is desired to remove the fastener R from the glass G to replace the glass G, or for any other reason, a wedge member such as a screw driver is slipped between the surface 31 of the glass G and the surface 41a of the leg 41 of the fastener R. Such wedging action results in a lifting of the fastener R which causes the flange 45 to slide upwardly and move away from the shoulder 22 so as to be disengaged therefrom. In other words, as the upward force is applied to the leg 41, the leg 42 is moved upwardly and laterally away from the glass G. Such movement is possible because of the reduced lower portion of the leg 42 provided by the curved surface 42b thereof. I

It is believed evident from the foregoing description that an improved window glass construction and fastener therefor has been provided which permits the assembly and disassembly of a pane of glass readily and without any special tools or special skill.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof and various changes in the size, shape and material, as well as in the details of the illustrated construction, may be made within the scope of the appended claims without departing from the spirit of the invention.
