4 Claims. (Cl. 160-394) This invention relates to an improved sash frame for a window or screen.

The improvement resides particularly in the construction or shape of the sash element itself. The linear frame element from which the sash is fabricated is so constructed that either linear edge may serve to receive a window pane. The element may serve to form the boundary frame of a sash or an intermediate part of a sash frame. ri`he element is further so constructed that it may serve as a screen frame and the edge of the screen may be secured thereto and the screen extended in either direction away from its line of securement and over either linear margin ofthe element.

Due to the particular shape and construction of the sash element, window frames or screen frames may be fabricated therefrom and without any waste of material. A long strip of such sash element may be cut into sections with beveled corners and the corners may be fitted together so that the pieces project in different directions away from each other and a frame can be built up without any wastage of material.

More specically, the opposite linear edges of my improved sash element are provided with identical channels each opening outwardly through its edge and each adapted to receive the margin of a pane of glass so that either edge of the sash element may be used to support the glass or both edges if a multiple pane sash is being built. Furthermore, the sash element is provided with a third channel designed to receive and retain a margin of a screen if the element is being used as a screen sash. This third channel extends linearly of the sash element between the other two channels and opens outwardly through a lateral face of the sash element. The two edge channels are disposed back to back and in a preferred embodiment of the invention, the bottoms of the two edge channels constitute the side Walls of the third channel and the third channel is so constructed that its side walls converge toward each other as they extend away from the bottom of the channel.

The construction is particularly adapted for embodi ment in a metal sash element and the side walls of each channel are tensioned toward each other so as to grip a glass pane or the like seated within the channel. When the sash sections are secured together to form a rectangular window or screen frame, the corresponding channels register with each other so as to form a continuous channel about the corner. It is therefore possible to provide angular corner braces which may be seated within vacant outer or inner edge channels or both to secure the sash sections together at the corners of the frame.

Other objects, advantages and meritorious features will more fully appear from the following specification, claims and the accompanying drawings, wherein:

The sash element of the invention is adapted, as hereinabove stated, to be used in the fabrication of either window or screen frames. It may be used in the fabrication of a frame which is divided into a plurality of sash portions, one of which may serve as a Window sash portion and the other of which may serve as a screen sash portion.

The sash element shown in the drawings is formed of sheet metal and is in the form of a linear strip. This strip might be formed out of sheet metal bent into the shape shown in Fig. l. Of course, the frame element might be formed of an extruded metal section.

In the various figures of the drawings, the sash element is indicated by the numeral 20. The sheet metal of which the element is formed is bent to provide two edge channels. One edge channel is indicated by the numeral 22; the other edge channel is indicated by the numeral 24. These two channels are disposed back to back, and they are substantially identical. Each channel opens through its linear edge of the strip. These channels are so formed that the bottom portions of the two channels are spaced apart to provide a third channel 26 which opens outwardly through a lateral face of the strip. The side walls of this third channel are formed by the bottoms of the two

edge channels

22 and 24, all as shown in Fig. 1.

When a frame such as the rectangular frame shown in Fig. 2 is fabricated out of a sash element -of the character shown in Fig. 1, a strip of the sash material is cut into sections along beveled lines, as shown in Fig. 13, and these sections are fastened together at the corners by right angled corner plates 28 of the character shown in Figs. 5 and 6. These corner plates are here shown as received within the edge channels. The walls of the channels may be indented as at 29 in Figs. 2, 6 and 7 so as to hold the corner plates in place. Rivets might .be used if desired.

In Fig. 5, which shows a corner of a lframe in elevation, the corner plate 28 is shown as received in the outer edge channel. In Fig. 3, which is taken on the line 3 3 of Fig. 2 through an intermediate frame member, the inner corner plates 28 are illustrated. In the structure shown in Figs. 2, 3, 4, 6 and 8, a screen sash is illustrated and a screen mesh 30 is shown as secured to the frame by having a margin of the mesh folded into the channel 26 and held therein by a strip of deformable material 32, as shown in Figs. 3 and 4. Such strip material 32 might be in the form of a tillet of soft material,

as for example lead, and this fillet is; pressed into the channel 26 on top of the screen. Due to the converging character of the side walls of the channel 26, the tillet is held in place and holds the margin of the screen securely in position. f r

It is apparent, as shown in these several figures, that a screen mesh may be extended in opposite directions away from the channel 26. If desired, a sash frame of the character shown in Fig. 2 might have a screen extending over one sash portion and a glass pane mounted in the other sash portion. If a glass pane were to be mounted in a sash portion, the interior corner plates 28 would be omitted. Y

Figs. 9 through 12 show a sash fabricated to receive a Window pane. The sash is put together in the same fashion as shown in the first eight figures of the draw'- ing except that the corner reinforcements are received in the outer edge channels only as shown in Fig. 9. Panes of glass 34 are received within the inner edge channels as shown in Figs. 9-12. These panes of glass may be seated within gasket material as indicated at 36 which gasket material might be in the form of a packing channel formed of rubber or some plastic compound might be used if desired.

The intermediate sash strip shown in Figs. 10 and l1 is shown as being held in place by the two glass panes between the opposite end members of the sash frame but not otherwise secured thereto,

Fig. 12 illustrates in detail how a corner of the Window sash is fabricated by providing a corner plate 28 which extends about the corner and is received within the outer edge channels and held therein by indentations 29, as heretofore described. In the structure shown in Figs. 9 through 12, the screen channels are not used at all.

It will be apparent, therefore, that this particular type of sash element is capable of being used to fabricate a window sash or screen sash. It will be seen that the outer edge channels and the inner edge channels, as well as the screen channel, all form continuous channels about the corner of a sash frame formed of this material. Sheet aluminum is a suitable material from which to form the strips and provides a highly satisfactory frame forggtwindow pane or a screen. The corner plates 28 mih also be formed of aluminum so that the indentations at the corners could be readily provided.

A sash frame member in the form of a linearly extending planar element the opposite linear edges of which exhibit lsubstantially identical oppositely facing channels extending throughout the length of the element and opening outwardly through said linear edges thereof, said element further exhibiting a third linearly extending channel disposed between the two edge channels and lying -in the plane of the channels and opening outwardly through a lateral face of the element, the opposed side walls of said'third channel inclined toward each other as they extend from the bottom of .the channel outwardly toward the mouth of the channel.

2. A sash frame member in the form of a linearly extending element the opposite linear edges of which exhibit substantially identical oppositely facing channels extending throughout the length of the element and opening outwardly through said linear edges thereof, the bottoms of both channels being inclined toward each other as they extend from adjacent one lateral face of the element toward the opposite lateral face thereof and terminating spaced apart to form a third channel having a restricted mouth, said third channel extending linearly of the element between the two rst mentioned channels with the bottom wall of the third channel lying in the plane of the two rst mentioned channels.

3. A sash frame member in the form of a linearly extending single strip of resilient material the opposite longitudinal edges of which exhibit substantially identical channels disposed back to back and extend throughout the length of the strip, the bottoms of said channels being spaced apart and the space therebetween defining a third channel extending lengthwise of the strip and opening outwardly through a lateral face of the strip, vthe side walls of the edge channels being resilient and normally slightly inclined toward each other as they extend away from the bottom of the channels and the side walls of the third chanel converging toward each other as they extend away from the bottom of the channel.

4. A sash frame member in the form of a linearly extending metal strip the opposite longitudinal edges of which exhibit substantially identical planar channels disposed back to back and extending throughout the length of the strip, the bottoms of said channels being spaced apart and the space therebetween defining a third chaniA nel substantially planar with the first mentioned channels and extending lengthwise of the strip and opening outwardly through a lateral face of the strip, the bottoms of said channels being inclined toward each other as they extend away from one lateral face of the element toward the other lateral face of the element.
