Beitnknown that ll, SAMUEL G. Fosrnn, a citizen-otl ythe United States, residing at lilestield, in the county of Union and State have invented certain new and useful Improvements in adjustable Window-Screens; and l do declare the fol- A, lowing to be -a`full, clear, and exact description of the invention, such as will enable it rippen tains to malte and use the same. I

rilhis invention relates to improvements in adjustable window screens and more particularly to an :improvement over the construction disclosed in United States Patent .1,022,312 of April 2nd, 1912. In the patented ydevice a screen frame was provided consisting of four rectangular sections telescopically` engaged with` cach oth r, a sheet 2O otwoven wire having` diagonal strands, was

received at its edges in channels oit' said `trame sections, and rivets were employed at spaced points for securing;- the screen to the irame. in actual practice, these rivets have 2.5 been foundto z( :reatly injure the wire mesh and to also interfere with smooth adjustment ot the screen to dil'erent and shapes. rihe principal object iny invention therefore is to devise a novel construco'tion for anchoringl the screen wire to the sectional frame, without the use of any rivets o1I like fasteners, the arrangement being' such that the sheet ot wire mesh is connected with the frame substantially throughout its perimeter.

The patent above vdiscussed included a pair ot' crossed brace bars which were pivoted together at their crossing point and also pivoted to the corners of the angular trame This construction has not proven entirely satisfactory and a further aim therefore is to provide an improved construction for retaining the brace bars in proper relation with the corners of the frame, without the necessity of employing any pivots.

lVith the foregoing` and minor objects in view, the invention resides in the novel construction andarrangement of 'parts herein after described and claimed, the descriptive matter beingr supplemented by the accompanying drawings.

Figure l is an elevation of a screen constructed in accordance with my invention,

showing the same extended horizontally.

ing the manner in which the screen may 'he iff extended vertically. i

-liX 1g. 3 is an enlarged 'vertical sectional view through one corner or the screen. A

llig. i is an enlarged horizontal sectif'inal view as indicated 'by line of Fig. 2. j

5 is a view similar to l*`ig.4, a'sindicated by line ot Fig. $3. v 'f f ln' the' drawings above brietiy described Y 7 the numerals l designate tour right angular frame sections whose arms are telesu'ipical'lvi connected to provide a complete rectangular traine 'which may be aiiljusted both vertiially and horizontally. Each jframe section 'is of substantially rectangular toi-m inv transverse section as shown in Figs. i and :3, one side thereo'tx however, being longitudinally split as shown at 2, providingl a relatively wide side iiang'e 3 and a narrower flange l'spaced outwardly therefrom to a slight' extent.

The sheet of screen w're passes' betweenf..

the flanges 5l and e through the split'or slot 2 and the edges of said sheet are abruptly bent as shown at 6 so as to hook around the flanges 3, thereby connecting the screen wire with the trame sections l, throughout the perimeter of the former. This provides a much .more effective anchorage than the rivets disclosed in the patent above referred to and insures much easier operation.

it the tour corners of the screen, the diagonal strands 7, which strands are free of attachment to each other, are cut oit as indicated at 8, providing for the necessary moveinentof said justed. ln some positionsot this frame, the cut away corners of the screen wire might forni openings allowing flies and other insects to enter, but in order to prevent this, ll provide four right angular corner clips 9 having parallel side lianges l0 between 'which the corners of the trame sections are soldered or otherwise secured. The tianges lOeXtend inwardly from the inner corners of the frame sections, suiiicientlyto close any openings which might be formed in the manner above set forth and it will be seen that the cl'fps 9 also serve to trame sehtions. Furthermore, these clips act 'to retain the ends ot' crossed brace bars l1, in the inner corners ot' the trame sections l, making it 'unnecessary to use pivots such as those disclosed in the patent above discussed. Une pivot ll however is employed at the y point where the barsfll cross each other.

substantially eiectively brace the' ing diagonal strands By employing the features of construction shown and described, a much more desirable and practicalscreen is provided, than that disclosed by Patent 1,022,312 and this screen may be `extended either vertically or orizont'ally-without any binding of the frame sections or tearing of the wire.

Since excellent results are obtainable from the details disclosed, such details are preferably followed, but within the scope of the invention as claimed, numerous minor changes may be made.

I claim:

1. An adjustable window screen comprising a frame formed of adjustably connected sections having longitudinal channels jointly extending around the entire trame, and a sheet ot woven. wire having diagonal strands tree of attachment to eachotl1er, the edges of said sheet being abruptly bentinto sai channels and hooked over one 'side thereof in sliding engagement therewith.

2. n adjustable window screen compris ing a frame Jformed ot' adjustably connected sections` said frame sections being hollow and having longitudinal slots at one side of the frame, and a sheet of woven wire havfree of attachment to each ot 1er, the edges of -said sheet being abruptly bent through said slots and hooked slidably around the portions of the framey y sections at one side ot' said slots.

window screen comprising a frame formed ot' `adjustably connected frame sections, each frame section being hollow and of substantially rectangular form in transverse section 3. An adjustable with one sidelongitudinally7 split to forni relatively wide e and narrow side flanges, the latter being outwardly offset from the former, and a sheet of woven wire having diagonal strands free of attachment to each other. the edges of said sheetbeing abruptly turned into the above mentioned split ot' each frame section and hooked slidably around the rela-tively wide ange thereof. A

4. An adjustable window screen comprising four right angular frame sections slidably engaged with each other to form a rectangular i' aune, a sheet ot' woven wire connected at its edges with said frame and having diagonal strands free of attachment to each other, nonextensible crossed braces pivoted together and having their ends located in the inner corners ot' said trame sections, and braces for the corners of said trame sections serving to retain said b `ace ends in said corners.

An adjustable window screen comprising tour right angular frame sections slidably engaged with each other to form a rectangular frame, a sheet of woven wire connected at its edges with said frame and having diagonal strands tree ot' attachment to each other, non-extensible crossed braces pvoted together and having their ends located in the inner corners of said frame sections, and corner clips secured on the corners of said frame sections and having side flanges retaining said brace ends in said corners.

In testimony whereof l have hereunto set my hand.

SAMUEL G. FGSTER.
