`This invention is'concerned vwith a new. and

Aimproved species of window screenfor-providing a ily and. other similar lpestulant.;insect-tight barrier especially yadapted to be removably mounted on the window framing of a home or similar building 1 l More particularly, this invention is directedto a new and` improved =typeof strip framing for mounting conventional: metal or .plastic mesh nently mounted' around the windows of'a Ahome or other building and the screening may-be eas- Window screen used for this purpose `isusually 20 composed of a wood or metal frame with the screening stretched tightly and permanently thereacross. -Such a screen is commonlyremovable from the window frame, but is not collapsible in the sense that the screening and framing are a..

`normally separated for storing, so that itisnecessary to remove vthe entire Trame and screening mounted thereon in order to store itv away for the winter. Such screensl are usually quite. heavy and cumbersome, making the Vjob of taking'them i ofi and putting them on a tiresome one. Further, their bulk does not allow for easy storage, especially inasmall space.. y

It is one of the objects of this invention to -provide a windowv screenv that is collapsible in,4

nature, so that the screen frame may be left in its mounted position around the window, and the screening completely .and l.freely disassociated from the frame. members for winter storage.

It is a further object-of this invention :to provide a new and improved metalstripframing which may be cut into convenient lengths-to -iit any size window without appreciable waste thereof. v F

It is a still further Yobject ofn this inv-ention.w to provide a new and improved way of mounting screening on permanently mounted strip frame members without the use vof any external iastenings, such as tacks or brads.

These and other objects willappear from time., to time as the following detailed description proceeds.

Now, in order to acquaint thoseskilled in the art with the-manner of constructing and -utilizing this invention, `I -shall describainconnectionwith, 55.

--lar shape.

the accompanying drawings, a certain'preferred embodiment of my invention. AFigure 1 is a front elevation showing a screen made in accordance with the terms of this invention, mounted on a conventional window A frame.

. Referring now to Figure 1. .a screenlll made in accordance with my invention comprises four sections of angular strip framing II adapted to be'mounted around a window frame I2, and suitably provided with projecting .hooks I3 over which conventional wire or plastic screening I4 may be stretched. y t .As `seen in Figure 2, the strip framing II may be conveniently mounted o n the window frame vI2 by means of ordinary wood screws I6, I8,

adapted to be inserted through suitable openings formed therefor in abase plate member I 1, which is integrally formed- With a vertically extending side wall member I8v of the strip framing. To produce such a framing, a flat rectangular strip oi metal, preferably of light material, such as aluminum, and comparatively thin, may be bent along its longitudinal axis to the desired angu- A 90 bend will be sucient to t most conventionalvwindow frames, and probably some slightly less angle Willbe desirable to accommodate window frames which are built with sloping or slanting sides. Such a slanted condition in the window frame is commonly met on *that the mounted framing may presenta vertical wall I8 for mounting the screening thereon.

,The hooks I3, herein shown as pointed, rectan'gular projections, although *other suitable vshapes such as triangular may be desirable as well, may be stamped or pressed out of the vertical wall member I8 of the strip framing at convenient intervals for fastening the screening I4 thereto. As hereindisplayed, the hooks are 1A to 1 inch is suiiicient to evenly hold and ten-y sion most screening.

In addition to the base plate I1 and side wall I8, the framing II may be optionally provided with a cover plate 20 for giving a finished outside appearance to the framing and for preventing inadvertent unhooking of the screening I4...

from the holding hooks I3. The cover plate may .be formed out of the same or similar material "as the vother framing members, being essentially a fiat, rectangular strip of material bent at any angle Aalong one margin to form a narrow lip l2I which isl adapted to lie in a parallel relation with the upper margin of the side wall I8, as shown in Figures 3 and 4, and provided for the purpose-of grippingthe screen between the lip and the side wall.

Suitable hinges

22, 22 may be mounted along the lateral marginal portion of the cover plate 20 opposite the lip margin `2I to provide connective 'means between the coverplate and the base plate. As herein shown, the hinges 22 may comprise rectangular extensions of the `base and cover fplates, rolled into semi-cylindrical shape and interconnected for hinging movement by `a wire pin or rod ,'23, such being Va conventional hinge construction commonly employed in sheet metal work.

As seen in Figures 3 and 4, the cover plate 20' fwill form the hypotenuse of a triangle formed by the cover plate, base plate, and side wall when in a closed condition. Suitable fastening means may be provided ,for securingthecover plate in its closed condition against the screening jI4 and 'side wall II. YAs herein shown, the fastening Imeans comprises va plurality of key-shaped fasteners ,25 which may be stamped out of the base plate 1I 'I to project upwardly therefrom through receiving slottedopenings 26 formed in registerlling position with the fasteners Yin the cover .plate '420, as clearly shown in Figure 2. Y Other suitable 'fasteners *may obviously be used, but this ltype 'affords the minimum productive expense and great simplicity of operation, as will be clear 'from jthe following description of the installation of this new'type of window screen.

Inorder to install a screen of `the type described above, it is merely necessary to cut 'the strip framing III into'the desired lengths `to iit the lwindow frames; cutting top, `^bottom and side /strips and cutting the side walls ata suitable mitre v29 'to nprovide-for a'tighttting corner joint. -When ascover plate 20 is provided -withithe framf ing, it will also be necessary 'to -cut back vthe corners of the -cover plate at a suitable mitre, such as is'shown in Figure2 at v31.), so that there is kno interference between the covers .at the-corners .of the completed frame. An ordinary tin snips or hack saw may be used to cut the framing. Having cut the frame strips to the desired length and 'beveled the corners of the cover plates, the framing may then ybe mounted to the window frame either insideor outside ofthe window, as desired, by meansof the screws I6.v With the frame thusly assembled around the window, a sheet of screening may but cut to the necessary length and stretched across the framing II, and held in place by means of the hooks I3. Insertion of the hooks about one-half an inch from the outside border of the screening will prevent unraveling of the screening. The cover plates 20 may then be closed with the fasteners 25 projecting `upwardly through the registering openings 26. By turning the heads of the fasteners slightly to the right or left, so that the heads no longer register with the slitted openings 26, the cover plate will be securely fastened down, as shown in Figure 3. When it is desired to store the screens, `itis merely necessary to unfasten the cover plates and remove the screening I4 from the hooks. The framing may be left on the window frame and the screen rolled up for storage.

It is thusly seen thata window screen is hereby provided which is easily installed, and capable of being readily removed and stored away in the winter in the form of a frameless roll, which is light, takes little storage space and is easily handled.

While I have herein shown and kdescribed one form in which this invention may appear, it will be readily understood that numerous changes, modifications and the use of equivalents may be used without departing from the spirit and scope of Vthis invention, and, therefore, I do not wish to be limited to the specic embodiments herein illustrated, vexcept as may appear in the following appended claims.
