WINDOW SCREEN.

Application ined March i0, 1928. serial No. 260,648.v

rIhis invention relates to an improved window screen, wherein the screen fabric is righ idly vsecured to a. rigid metal frame, and the metal frame slidably mounted in an especially constructed outer wooden frame. y

lVhat I aim to do is to provide a simple and inexpensive structure characterizedby this two-part inner and cuterframestrncture to facilitate construction, assembly'and repair. y

The particular structural'v details which Vserve to characterize and individualize this particular contribution to the art' will become more readily appare-nt from the following description and drawings.

In the drawings Figure l is a side elevation of a screen constructed in accordance with the invention, with portions broken away to disclose thearrangement of details more clearly.

Figure 2 is a central vertical sectiontalien on the line2-2 of Figure l.

Figure 3 1s an enlarged fragmentary detail section showin@v resilient retaininsr cli as 7 o r .a

forming a part of the invention. y In thevdrawing, the numeral 4 designates generally the wooden frame which is of usual rectangular configuration. rIhis is made np of spaced parallel side strips'vand 6, having filler strips 7., fastened therebetween uto provide guideways or channels for thev slidable section of the screen. The right hand filler strip 7 as shown in Figures l and 3 isprovided with spring retaining clips 8, these' proj ecting into the complemental guide channel; Itiis desired to 'distinguish the top fillerstrip by the numeral 9 as it is intended to be removable and isv held `in place byv retaining screws 10. i

l Ihe slidable section comprises suitable` 'tlf screen fabric ll, stretched tautly and fasvtened to a metallic frame 12.

InV assembling, the top retaining 9 is removed and the fabric screen and Vits me.-

tallic frame is slipped into t-hewchannels inf15` a manner to. cause the clips 8 to engagevone end bar and to hold it in place. The clips operate as anti-rattling means. After vthe screen is then slipped into the wooden frame, the strip 9 is placed back and the screws fas- 50 tened to hold the two frames in assembledl relation as shown in the drawings. The advantages of this arrangement are quite apparent to persons skilled in the art to Y which the invent-ion relates, and therefore, a '55 more detaileddescription is regarded unnecessary.

vMinor changes in shape, size, and arrangement of parts comingwvithin the field of 1nvention claimed may be resorted to, if desired. ,'60 vIclaim:r f Y A window lscreen comprising an outer frame .embodying frame bars, at least onefof which is composedof spaced parallel parts,

and a filler strip arranged removably therey between, said side bars being of .channel shaped cross section, an inner frame slidably received in the channels and heldin 'place by said filler strip, and screen fabric carried by said inner frame, lsaid outer frame being` constructed of wood and said inner frame beingl constructed of metal, said outer frame having Y one of its side bars provided with resilient retaining cli s extendingl into the adjacent channel anc engaging the adjacent side bar of the metallic innerframe. v l

In testimonyvwhereof I affix my signature.
