U 1T ED ST T wears- METAL wxnzoow SCREEN Application filed September 1, 1927. Serial No. 216,814.

An object of this invention is to provide an all-metallic window screen which will snugly fit the Window frame and exclude at its points of union with the frame, weather, and having a minimum of projection from the face of the window frame. 7

Another object is to, provide a rigid allmetallic rectangular frame having at its inner margin a continuous channel into which the edges of a section of wire cloth may be turned ind held therein by a sectionally yielding filet. Another object is the saving of time in the placement of a section of wire screen in a frame.

' A. feature of this invention is a cloth securing means which consists of an open-ended trough which receives the bent end of the wire cloth and a sectionally yielding retaining o strip which is forced into the trough over the turned end of the cloth. I v 1 An advantage arisingout of the invention is the holding of a section of wire cloth uniformly at its edge in contra-distinction to the :45 securing of the cloth at intervals'as is common.

Anotheradvantageis that the wire cloth may be; readily removed and a new clothsub- 'stitute'd therefor, without injury or distortion so o'f'the frame. a H v a v Other objects, advan'tagesand features of invention may appear from the accompanying, drawings, the subjoined detailed description and the appended claims a j e The accompanying .drawings illustrate the invention.

oF ic-E f 1 is a window screen constructed inaccord ance with this invention and is shown suspended from supports Qsecured to a window frame 3 embedded in a wall 44 a fragment of which is shown. 5 indicates the stiles of the screen frame which are j oinedby rails 6, said stiles and rails having mitered ends? so that a neat joint can be effected. A gusset'plate 8 so designed as to conform-with the sectional configurations of the stiles and rails to cover each corner of theframe and is spot welded in place.= I a The "screen frame-has a flange 9' that overlaps the exterior of window frame 3 and a rabbet 10 bent substantially at right angles thereto so that the, rabbet 10 projects within the window frame and provides an additional seal between the' screen and windowframes. I r v The inner edge 'ofeach ofthe stiles and stantially parallel to provide a CQILtiIl'IiOIUS groove 14 around the inner portion of screen 'Alfillet 15 preferably madejof wpQd although 'wire-or metal .stripsi-of requisite lengths, or metal bands of suitable proportions wouldbe satisfactory for thepurpose,

. is used to bind and lockbentj-ov -ti of the wire cloth 16 in th gmoyehml The .fil'let- 15 has parallel sidest-l'? and ;;1,8.,.to,conform with the-sides 12 and-13 of thebent porframe is reversely bent as at 11 so thatthe'sides'12 andlfii are. sub-' tion 11 so that as the .fillet;-1 5 is drivenjnto ,1

symmetry :ofthe finished screen, making. it- 1 more'pleasingto the.eye. i The supportsfl, are adapted-to secured 2 so that the member 21 fits flush with the outer edge of the window frame. An arcuate tongue 22 integral with the member 21' is adapted to extend through a slot 23 in the overlapping flange portion 9 of the upper rail, 6 and gusset plate 8 and said arcuate portion 22 provides a rest upon which the screen frame 1' is suspended. A hook 24 secured to the lower rail 6 is adapted to engage an eye 25- secured to the window sill 26, for the purpose of holding vthe screen snugly against the frame in closed position.

' .By reason of thecontinuous groove 14 and the fillets there is economy in wire cloth and economy in time in its securement to the frame. The wire cloth economy is due to the requirement of only a slight inturned margin of the cloth to finish over the exposed face i of the trough. And the time economy is due to only a requirement of turning the edges of the cloth to direct-them into the trough and the driving of a filletinto the trough along with the turned edge. And the window'screen space economy is due to the fact that all members and parts are held within certain parallel lines, namely the outer flange of the frame and the inner edge of the rabbet and the inner bent-over portion of thegroove as previously set forth, an advantage of which is that the whole of the window sill is unoccupied and that there are no parts rojectin-g outwardly from the window rame.

I claim:

1. A metal window screen frame member comprising in its section a *relatively flat flange for overlapping the face of a window frame; a relatively angular rabbet for engagement along the jamb of the window frame and at its margin. opposite said flange a reversely bent channel.

2.A metal window screen frame. member comprising in its section a substantially flat flange, a rabbet extended inwardly from said flange; a margin forming a channel having substantially parallel sides.

3.; In combination with the mitered end of a stile and of a rail, each including in their sections a flange for overlying the face shapedto conform therewith.

4. In combination with the mitered'end of a stile and of a rail, each including in their sections a flange for overlying the face of a window frame; a rabbet for extension along the jamb of the window frame and a reversely bent margin forming a channel; of a corner plate covering the mitered ends of said frame members and sectionally shaped to'conform therewith; said corner plate being spot IZveldedto the mitered ends of the frame memers.

5. In a window screen frame comprising stiles and rails and constructed with a flange along the outer. edge of said stiles and rails and with a rabbet at substantially right angles'to said flange; bent-over portions along the inner edge of said stiles and rails to form a groove; said flangelying in approximately thesame plane as the outer edge of the bentover portion of the groove, and the inneredge of said rabbet and inner edge of the bent-over portion of the groove lying in substantially the same plane to effect a symmetry of proportions and economy of window screen space.

6. In a window screen frame support; a shank, a flange at right angles to said shank, a second flange bent upwardly and at right angles to said first flange and an arcuate tongue projecting outwardly and upwardly from said second flange; said shank and said firstflan'ge being perforated to receive securing-means.

7 ..In a window screen frame support; a

shank, a flange at right angles to said shank,

said.flange being sheer on one side of said shank and oppositely projecting from the other side of said shank, a second flange, said second flange being at right angles to said first flange and extending upwardly therefrom and an arcuate tongue projecting upwardly and outwardly from said second flange and means tosecure said support to a window frame.

8. A metal wmdow frame element, a section of which comprises a vertical flange for engagement over the face of a window frame; a substantially horizontal rabbet formed as an integral continuation of said flange for engagement along. the jamb of a window frame; an .element forming a continuation of the rabbet and bent to stand substantially in the plane of the flange, and a trough having sides which parallel said last mentioned element and having its end next the rabbet open to receive a sheet of wire cloth.

In testimony whereof, I have hereunto set my hand at Los Angeles, California, this 26th day of August, 192

ELMER T. GALLEY'.
