To may concern:

-Be it known that I, AMY E. DAVIS, a

of the city, county, and State ofNew York, have invented'a-new and useful Improvement in Window Screens, of which the following is a specification.

' The object of my invention is to provide a screen of this class inwhich a suitable fabric or other screening medium may be' removably mounted in a frame so that it may be readily removed cleanedand restored.

A furtheiobject of my invention is to provide a screen frame which will properly cooperate with the screening medium which hasto hold the same when in use or permit from the frame and a ready removal when desired, and alsoto.

allow for any expansion or contraction, which may be necessary when the screen is in use. I

These and other objects are accomplished b my invention wherein a frame is provided with hooks and a screening medium is provided with a wire or string which will be passed over the hooks and drawn tight so as to stretch the screening medium in place, which the preferred embodiment of my invention is a fabric.

- For a more particular description of my .invention, reference is to be had to the accompanyin drawing, forming a part hereof, in whic Figure 1 is a plan View of a frame with a screening means mounted therein according. to my invention.

Figure 2 shows a portion of the frame.

Figure 3 is a view of the complete screen.

Figures 4 and 5 are sectional views of the screen shown in Figure 3, the sections being taken so as to illustrate different cross sections of the frame.

' 'The remaining figures show modifications, Fi re 6 showing a wooden frame with strips hinged thereto, one at each edge.

Figure 7 shows a portion of the structure shown in Figure 6 with the strips swung back to reveal the wire or string with the screen medium.

Figure 8 is a sectional view taken on the line 8-8 of Figure 6, looking in the direc-. tion of the arrow.

Figure 9 shows a device for holdinga wire or string in the embodiment of my invention shown in Figures 6, 7 and 8.

Figure 10 shows a further embodiment of my invention wherein the screening medium ,-is secured to strips inside the frame.

Figure 11 1s a sectional view taken on'the line. 11-11 of Figure 10, lookinginthe direction of the arrow.

' Figure 12 is a pers ective view of a strin holding hook. p g

Figure 13 shows the strips and screening ,mechamsm of Figure 10. y Flgures 14 and 15 show a metallic expansion device suitable fora frame similar to thatsh'own in Figures 1 to 5. inclusive, Figure 15 bein a sectional view of the structure shown in igure 14. Throughout the various views of the drawings, similar reference characters designate similar parts. v In all embodiments of my invention herein disclosed a screening device 1 is composed of a screening means as a cloth 2 and a frame 3. This frame may be of metal or of wood," as desired. In any event this frame is provided with suitable hooks or lugs 4 and 5 which are spaced at suitable intervals, as indicated, to receive a continuous wire, drawing stringor similar device 6 which is mounted in a suitable continuous hem 7 of the fabric 2. Both the hem and the string extend around all edges of the fabric and the string is made continuous so that it may be caught by the hooks 4 and 5, as indicated. The hooks 4 cooperate with the frame to hold the cord 6 tight between them and the frame. without any tieing or other fastening. The string may be wrapped around any of the hooks 4 so that such hooks may hold the string tight on both sides and in this way take upslack. p p

In the embodiment of my invention shown in Figures 1 to 5inclusive, the frame 3 is composed of a metal strip with a flat base 8 with a vertical exterior web 9 which 'is bent.

the interior and over the base 8 towform the, web 11. At intervals this web 11 is cut away and tongues are bent up and back to form the hooks 4 and 5 above mentioned. At other places the webv 11 is arranged so as to form larger tongues 12 which are formed by having webs bent, as shown in Figure 4.

The tongues 12 run parallel to the webs 9 and 10 and have only a slight space between them which receives the vertical edge 13 of the cover piece 14 which covers the hem .7,

and string 6 and the hooks 4 and 5 and the tongues 12 so as to make a neat looking frame. Each strip 1% has a miter edge at its end so as to fit with the adjacent strips which run at an angle of 90 degrees thereto, as shown.

In the embodiment of my invention shown in Figures 6, 7, 8 and 9, awooden frame 3 is recessed at its inner edge and provided with strips of wood or similar material which are mitered at their ends and hinged at 16. These strips may be thrown back, as shown in Figure 7 where the fastening hooks 17 are revealed. These hooks have sharp'lower ends and bent upper flanges so that they may be inserted adjacent to a. vertical wall with a portion which directs the slightly separated and so placing of the wire or string 6 and another portion which is bent to hold it against the frame 3.

-' In the modification of my invention shown in Figures 10, 11, 12 and 13, the strips 15 are secured together and hinged to the frame 3 by means of two hinges 16 which are preferably placed at one side. In this embodiment of my invention, the strips 15 are re c'essed at their rear to form a rabbet 18 which receives a book 19 which is shaped substantially as shown in Figure 12 with a sharp point and a flat hooked top which readily holds the shirring string 6, as indicated, so that the fabric or other screening means 2 is stretched close to the strips 15 and hold securely thereon.

In the embodiment of my invention shown in Figures 14 and 15 the webs 9 and 10 are are the webs 8 and 11 in one part 20 so that a corresponding part 21 may fit therein. Of course the part 21 is slightly smaller then the part 20, but as the difference in size is only the thickness of the metal, it is too slight to attract notice. When the embodiment of my invention shown in Figures 14 and 15 is employed,

1 means for enabling them to the frame 3 maybe placed directly under a sash and then expanded so as to fit the grooves in which the sash slides. If desired, the frames may I suitable way or provided with any suitable fit under a window sash or in place of a window sash.

While I have shown and described some embodiments of my invention, that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of theannexed claims.

Having thus described my invention, what I claim is: I

1.. A frame with books, a screening means with a continuous hem at its edges, and a continuous drawing string having po tions within the hem and exposed portions pass- 1 ing out from the hem and over the hook so as to hold the screening means in place.

2. A frame with hooks, a screening means with a hem at its edges, a drawing string passing through the hem and having ex posed portions passing over the hooks so as to hold the screening means in. place and means for concealing the string and hooks.

3. A frame with hooks, a screening means with a hem at its edges, a drawing strin passing through the hem and having exposed portions passing over the hooks so as to hold the screening means in place, and said frame comprising means for permitting it to expan 4. In a device of the class described, a frame, a screening means with a continuous hem at the edges, a continuous drawing string passing into and out of the hem so as to be partially concealed andto have exposed loops and means for engaging the exposed loops of the string and securing the same to the frame so that the screening means is stretched in the frame.
