This invention relatestofwindows, and

particularly to windows" in which theisashes swing about axes intermediate their ends;

I My invention is directed toward provisions for securing effective "screening windows of the specific type refg'e'rred' to,{--w'1th assur a'nce of a perfect seal at the region of the swing'ng axes of the sashes throughout they range of sash movement.

1 This desiderata I attain with means applicable to pivoted windows of standard construction, along'the swinging axes'ofltheir sashes,to continuously'contact with contigu- J ous edges of COmplementaIsCreens'at opposite 15 sides of said axes and respectively exteriorly and interiorly of the windows, thereby to function as aseal'acro'ss thegapneces'sitated bysuch relative allocation of the screens.

With reference to the drawings, Fig. ;I'1s

avertical section through a window structure with a pivoted sash; and screeningprovisions conveniently embodying my invention.

Fig, II is a view similar to Fig: If although more fragmentary'inflcharacter, showing the 11, of right angle cross section. Within the frame 10' is mounted .a sash 12 with a frame formed of perimetric railjsf 13-.as well. as a a, conventional muntin orintermediate rail 14,

also of metallic angular cross section. The sash 12 is mounted for movement about a horizontal axis intermediate its ends on hingepivots 15 in the present'inst'ance ofi'set inward somewhat but in line withth'e rail 14,

I the hinges being such that the'upperrsash edge swings inward in opening. In closed position it will be'noted that the vertical flanges of the upper and lower rails 13j0 f the sash 12 contact with the horizontal flanges of the outer frame rails 11,.respectively atthe 128mSefial no. 2883401 wr nnow ooivsrrnuorrorr in and theout sides of'thewindowstructure, sothat weather tight juncturesare formed at: the designated regions. suitable latch comprehensively designated-16 the sash 12 in closedposition'l I As hereinbefore pointed'out, the-present v invention is concerned :with'screen protection .for a pivoted Window ofthe" type just briefly serves to lock 7 described. iTothisT'end I provideabove and below the pivot axis 15,1and respectivelyqiexteriorly and interiorly the window-,iscreens "WlllCll are comprehensively designatedby the numerals 20, 21in Figs. I and II. i

v The upper. screen is supported at the bot- I I tom by recessed members :in-theform ofclips -22 suitably attached tot-opposite 'jambrails of the frame10',and heldin place atthe top *by a 'transverse'ang'le-strip 24. 'As shown,

this'angle strip 24 is fastened by screws 25 along'the upperrail l l of the frame 1(l',",and

oyerlapsthe upper edgeo'f the-screen 20; By virtue of a clearance afforded Within the strip 24:"above the screen 20, the latter vcan-be lifted i q'uired toper nitflateral deflection incidental ,-to removalfrom' the window. This,.itwill be seen, can all be'readily accomplished from doors-when the; sash 112 is opengithe arrangement being especially advantageous where accessat the exterior is difficult. as for example on .the upper Jstories of tall" buildingsi he lower or in side screen i2l rests'at thelbottom within an angle clip 26 affixed by screws 27 to the bottom rail ll'iofthegfraine l0, and is secured bywing: screws 28-taking "into'the' jamb rails ofsai'd frame.*f- 1 To accommodate the swingof the'sashil2, j a substantial interval isireqiii'red at the region 'i of tlie pivot axis -15 .;betwee'n the contiguous horizontal edges bfthe screens: 20, This sintervaljI close with the aid of sealingstrips :3O, 31vfashioned from sheet metal, the same being illustrated in perspective inFigs.

The sealing strips 30,

ing. In the present instance I have shown them as-secured to the intermediate rail 14 of=the sash 12, the strip being angularly configured as at 30?) to suit the contour of said rail and to admit' of interposition between said rail and the window pane 32, with the horizontal flange 800 occasioned by the angulanbending at 30?) resting onthe web of the rail. The companion strip 31 is similarly flanged laterally as at 31?), and flange, together with the flange 800' of the strip 31, are concealed with'the putty or cement employed to secure the'glass 32 in place. The dissimilarity in the cross sectional configuration-of the sealing strips'30, 31 is for the most part due to offsetting of the pivot axis 15to one side ofthe plane of the sash 12. In cases where the pivot lies directly in'the medial plane of the sash, the aforesaid strips may be quite similar in shape, or even identical;

While I have specifically shown and described my invention in connection with a window having a sash swingable about a hori zontal pivot, it will be obvious that the same can be embodied with advantages correspond- I ing to those herein set forth in windows having sashes swingable on vertical pivots interme diate ends.
