Application filed April 19,

The invention relates to window screens and more particularly to a screen having a frame wherein the Screening fabric is removably held in place.

The objectof the invention is to provide a screen having a substantially channel-shaped frame, the screening fabric being arranged to be removably connected to the frame by at taching the corners of the screening fabric to the corner portions of the frame with a re movable attaching clip, the edges of the screening fabric being clamped within one side of the channel frame by means of rods having spaced bends or projections therein whereby the rods may be quickly and readily snapped into place within the channel frame, clamping the adjacent edge of the screening fabric-within one side of the frame.

Other objects of the invention include the provision of a screen frame which is open upon its inner side, permitting a circulation of air through the same at all times in order to keep the frame dry and free from moisture. thus preventing corrosion of the parts; and

" to provide a simple and inexpensive method of forming and assembling the frame.

An embodiment ofthe invention is illustrated in the accompanying drawings, in which Figure 1 is an elevation of the inner side of the improved window screen;

Fig. 2, an enlarged section on the line 2-2, Fig. 1;

Fig. 3, a detail perspective view of one of the corner clips;

The frame indicated enerally at 1 is composed of members 811%St311tlitllj channel- '1927. sr1a1 No. 184,871.

, portion 7 as at 5. The curved portions 3 and 4.- thus form retaining groovesfor a clamping rod to be hereinafter described.

As shown in Fig. 2, the outer flange portion 2 extends from the web portion 7 of the channel member a greater distance than the angular flan e 5 thereof, which flange 5 terminates at a pomt spaced from the plane shown at 6,passing through the outer edge of the portion 2 parallel with the web portion 7 of the channel frame. The web portion 7 and the plane 6 are also parallel with the normal plane of the screen as shown at 12.

Although this frame may be made up in anywell known manner, it is preferred to form the frame of a single strip of metal having angular cut-out portions at the corners whereby the frame may be formed or bent into rectangular shape, the edges of these cut-out portions meeting as shown at 8 in Fig. 6.

An aperture 9 may be formed upon each side of each cut-out portion to receive the tangs 10 of the corner plates 11 whichtangs are bent back upon the inner side of the frame, thus forming a rigid one-piece frame. If desired, the apertures 9 and tangs 10 may be dispensed with and the plates 11 may be welded or otherwise connected to the corners of the frame.

down beneath the corner of the flange 5 of the frame and clamps the same against the inner flange apex 21, while the nose portion 22 of each clip 13 engages inside the Gil outer flange apex 20 as shown at 23. For the purpose of qulckly and easily removing these corner cli s when it is desired to remove the screen fa no, a loop 15 may be pressed or stamped upon each clip.

The free edges of the screen fabric may then be bent down over the edges of the flanges 5 of the channels which go to make up the frame, said channels being substantially parallel to the normal plane of the screen, and the clamping rods 16 are then placed in position. Each of these clamping rods may be provided with the projections or loops 17 at spaced intervals, the portions 18 of the rod, between said loops or projections being preferably 1btnved slightly outward as best shown in These normall bowed portions 18 of the rod engage the ownturned edge portion of the screen fabric against the retaining groove formed by the curved flange portion 4, and the projections or loops 17 are then pressed downward into and engage the retaining groove formed by the curved flange portion 3. The bowed portions 18 are thus sprung when the rod is retained within the channel so that said portions are maintained parallel with the flange groove 4, thereby maintainin a clamping contact against the screen fa ric throughout the entire length of said portions. Of course it is understood that the natural inherent resiliency of such a metal rod will cause the same to again become normally bowed as at 18 when the rod is removed from the channel.

With this construction of frame it will be seen that when the screen is placel in position upon the outside of a window frame, the only portion of the screen which engages the window frame will be the inner edge of the flange 2, as shown in Fig. 2, the broken line 6 representing the plane of the window frame.

As shown in this figure, the screen fabric and the remaining portion of the frame are all spaced from the window frame, thus permitting a circulation of air through the interior of the channel frame at all times in order to uickly dry any moisture which may enter t e same and prevent corrosion of the frame and screen.

When it is desired to remove the screen fabric in order to replace the same, it is only necessary to remove the clamping rods 16 and the corner clips 13 when the entire screen fabric may be liftedfrom the frame and a new fabric placed therein in the manner above described.

I claim:

1. In screen frame construction, a channel frame member substantially parallel with the normal plane of the screen, a clamping rod in said channel having spaced portions parallel with one portion of the channel and having spaced rojections engaging another portion of the c annel, and a screen fabric edge por- 1,7os,ses

tion extending into said channel and securedthereln between the parallel 1portions of the clamp ng rod and the channe 2. In screen frame construction, a channel portion, a clamping rod in said channel hav-- mg spaced portions parallel with said angular flange and having spaced projections enaging the other channel flange, and a screen fabric edge portion extending over said angular flange and into said channel and secured therein between the parallel portions of the clamping rod and the channel.

3. In screen frame construction, a channel frame member substantially parallel with the normal plane of the screen, one flange of the channel extending inward from one edge of the channel at an angle from the channel web portion and the other flange of the channel extending away from the web portion a greater distance than the angular flange, a clamping rod in said channel having s aced portions parallel with said angular ange and having spaced projections en aging the other channel flange, and a screen abric edge portion extending over said angular flange and into said channel and secured therein between the parallel portions of the clamping rod and the channel.

4. In screen frame construction, a channel frame member having in cross section, a web portion substantially parallel to the normal plane of the screen, and flange portions curved inwardly from the web portion forming retaining grooves, one flange extending inwardly from the curved portion at an angle from the web portion, and the other flange extending from the curved portion away from the web portion and terminating a greater distance from the web portion than the angular flange,aclamping rod in the channel hav-- ing spaced portions parallel with one of said retaining grooves and having spaced projections engaged in the other groove, and a screen fabric edge portion extending over said angular flange and into one of said grooves and secured therein between the parallel portions of the clamping rod and the channel.
