These four corner sections I2,1`55

larged detail sectional view of the inner frame 2. Itis by means of the hollow rolled beads I6 and I'I'that the four corner sections of the inner frame 2 are telescopically united. e

Adjacent the lower oppositev corners of the outer screen frame as well as adjacent theupper corners of the outer screen frame on the inside thereof hanger plates I!! and 2i! are secured in any suitable manner preferably.4 ,electrically welded or otherwise, and these plates have elongated slots 2! and 22, through which screwV eye` hangers 23 and 2d engage and are threaded into the sill of the window frame and into the lower i rail of the upper sash,` for the purpose of anchorvingr the window screen in place.

y Obviously upon examining Figure, 1 of the drawings it is possible to lower the upper sash, causing the perpendicular legs of` the upper corner sections of the outer frame to telescope the perpendicular legs of the 'lower' corner sections, thereby providing a Ventilating air space between the yupper rail of the upper sash and the upper horizontal i rail of thewindowframe as lshown at25. A

smallrigid window screen (not shown) may be inserted in said space 25. Also it is obviously possible to restore the upper sash to its normal position asshown in Figure 1, by rendering the perpendicular legs of the four corner sections ,eX- tensible. It is also obvious from an inspection of the drawings that the window screen shown in FigureV 2` has been reduced`in size transversely as well as vertically.

These hanger plates I9 and Z on their adjacent ends'have ears 2G provided Vwith iinger engagingopenings 2'! permitting of rrn holds on the sections of the screen frame, 'for the purpose of adjustment. f

Referring toFigure 7 it is obvious that the horizontal and perpendicular legs of the four corner. sections of the inner screen frame are telescopically united topermit of extensibility as well asreduction of said inner screen frame. In order to prevent entire ydisconnection telescopicallvof the f our corner sections of the inner screen frame,l certain walls of the horizontal and perpendicular legs of the four corner sections of theinner screenframe haveregistering slots lim for thereception `of headed two leggedv pins i8, the two legs of said pins passingrthrough the registeringslots and being bent over in opposite directions at E ib shown in Figure 6, acting to retain the four corner sections of the inner screen frame in telescopical joined positions.

The lower rail of the outer frame of the screen frame is provided with a plurality of perforations 1,997,445 28 to permit the draining off of any-water that may collect therein.

From the foregoing description together with the construction illustrated in the drawings it is obvious how the various corner sections of. the

inner and outer screen frames may be telescopically adjusted to reduce the size of the screen frame as well as rendering same extensible. Obviously Vfrom thisV construction itV is apparent that whenladjusting the various sections of the screen frames it is necessary to have various areas ofwire fabric screening in order to provide for the various adjustments.

' It is obvious thatby giving the screw eye hangers a partial or quarter turn so that the eyes ,of said screw hangers will extend in alignment with the ,slots 2I4 and 22 of the hanger plates KI9 and (2|, it is possible to move the four corner sections of the outer screen frame, so as to remove the window screen from the window frame.

The invention having beenset forth, what is claimed is:

l. ln a screen frame,` the combination with an vouter frame comprising four telescopical frame sections, of an inner screen frame likewise comprising four telescopicalcorner sections, the corner sections of the inner screen frame provided ner sections of the inner screen frame provided with hollow'rolled beadscaused to telescope, an area of wire fabric screening with its edge portions rolled within certain ofthehollow beads,-

thereby mounting the screening, the opposed walls of the outer screen,` frame having* hollow rolled beads to telescope and to impinge'on the screening, and means to prevent slipping of the telescopical legs of the four vcorner sections of the outer screen frame. Y

3'. In a screen frame, the combination with an outer frame comprising four telescopical frame sections, of an inner screen framerlikewise comprising four telescopical corner sections, the corner sections of the inner screen frame provided with hollow rolled beads caused to telescope, an area of wire fabric screening with its edge portions rolled within certain of the hollow beads, thereby mounting the screening, vthe opposed walls of the outer screen frame having hollowrolled beads to telescope and to impinge on the screening.Y
