FRAME ron wrivnowwscnnnns.

Application med August 26, 1926. sei-"iai ivo. 131,773.

The object of this invention is to provide a frame for window screens of simple, durable, and comparatively inexpensive construction.

A further object of my invention is to provide a window screen frame which may be securely held in position with respect to a window frame, the screen frame coacting with the window frame in such a manner as to be easily removable from either the inside or outside of the building in which the window frame is built.

More particularly, it is my object to provide a screen frame construction consisting of an ordinary screen frame to which a movable element is secured and spring-held in a predetermined position spaced from the side of the screen frame.

Still a further object is to provide a cover device adapted to be associated with the screen frame in such a .manner as to conceal the springs and to provide a fly-tight joint between the screen frame proper and the movable element.

lVith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of my improved screen frame construction.

Figures 2 and 3 are enlarged sectional views on the lines 2-2 and 3-3 respectively of Figure 1; and

Figure 4 is a disassembled perspective view of the parts of my construction.

On the accompanying drawings, I have used the reference numeral 10 to indicate the top bar of a screen frame. The lower bar thereof is indicated at 12 and side bars 14 and 16 are provided for connecting the

bars

10 and 12 together. A center bar 17 may be provided if desired.

The side bar 16 is provided with openings 18 through which rivets or the like 20 extend. A movable bar 22 is slidably mounted on the rivets 20 and springs 24 are provided encircling the rivets and interposed between the

bars

16 and 22.

Washers 26 are provided on the rivets 20 and cotter keys 28 are provided for the purpose of holding the parts assembled together relative to each other. As clearly shown in Figures 2 and 3 of the drawings, the washers 26 are countersunk.

From the foregoing description, it will be obvious that the movable bar 22 is held in a predetermined position relative to the bar 16 by means of the springs 24 and the position of the movable bar 22'is limitedby the countersunk heads 30 of the rivets 2O and the cotter keys 28. For concealing the springs 24 and bridging the gap between the bar 16 and the movablebar 22, I provide a cover member comprising a strap of metal formed into side members 32 and a top connecting member 34. The cover member is secured to the bar by tacks or the like 36, as best shown in Figure 2 of the drawings.

From the foregoing description, it will be obvious that I have provided a screen frame, which normally has a given Width, but

which width may be slightly reduced for allowing the screen frame to fit a window frame of slightly less width than the normal width of the screen frame.

Therefore, when the screen frame is placed in position relative to the widow frame the springs 24 serve to cause resilient engagement between the side bars 14 and 22 lof the screen frame and the side jambs of the window frame.

On my drawings, I have not illustrated any screen wire covering the'frame, but such screen wireis placed on the frame and secured thereto by screen molding in the ordinary manner.

For convenience in handling the device when installing or removing the same, I provide a handle 38. When the screen frame is installed relative to the window frame, the movable bar 22 is first placed in engagement with one side jamb of the Window frame and then the side bar 141s forced in position by a slight movement of the screen frame in the direction of the arrow 40.

Some changes may be made in the construction and arrangement of theparts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claim, any modified forms of structure or use of mechanical equivalents, which may be reasonframe, means of support comprising a plurality of rivets having heads countersunk in said element, said rivets extending through said bar and said element, springs encircling said rivets and interposed between said bar and said element andkeys in said rivets adjacent said side bar for holding the parts in 1,722,572 s .n -i

assembled position and a U shape cover member extending ovei` the top of said frame and downwardly on each side thereof 10 to conceal said springs.

Zearing, Iowa, `August 24:, 1926.
