This invention relates to improvements in window screens and embraces a screen frame adapted to be pivotally mounted along one of its longitudinal edges in a window casing 5 and provided with mechanism assoclated with the window frame and the screen frame to facilitate mounting of the screen frame and latching of the same from the interior.

It is an object of this invention to provide a window screen frame constructed of interfitting inner and outer frame sections between which the screening is adapted to be clamped. v I

' It is also an object of this invention to provide an improved screen frame having a sleeve integrally formed'along one of the longitudinal members thereof to carry pivot pins for pivotally mounting the screen frame in a window frame.

It is a further object of this invention to provide an improved screen frame adapted to be pivotally mounted in a window frame and having a shiftable latch plate mounted on v the inner side ofthe frame adapted to be moved into latching engagement with a latch plate secured to the window frame.

It is furthermore an object of this invention to provide an improved screen frame having pivotrpins engaged in the end of one of the longitudinal members of the frame to facilitate pivotal mounting of the screen frame in a window frame by means of an improved bar and bracket arrangement mounted on the sill member of the window frame.

' It is an important object of this invention to provide an improved screen frame adapted to be readily mounted in a window frame to swing outwardly on a vertical axis and having animproved bearing block for the reception of the lower pivot pin of the screen frame, with said bearing block adapted to be slidably mounted in position in a bracket secured to the window frame sill to hold the screen frame in proper position to permit latching of the screen frame from the interior by means of an improved shiftable latch plate positioned for coaction with an apertured plate secured to one of the uprights 5c of the Window frame.

TENT OFFICE Other and further importantobjects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

This invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

Figure llis an enlarged detail section of the modified form of screen frame taken on line XI-XI of Figure 10.

As shown on the drawings:

The reference numeral 1 indicates a wall of a building having an opening therein in which a window frame or casement is mounted. The window frame comprises vertical side sills or upright frame members 2 and 3 connected at their upper ends by a horizontal cross member 4. The lower ends of the framc members 2 and 3 are connected by means of a sill 5 provided with a sill extension 6.

Securely mounted on the middle portion of the inner face of the easement sill member 3 is a latch plate 7 provided "with-aslot or opening 8 which communicates with a slot or recess 9 cut in the casement sill member '3 for the reception of a locking member hereinafter more fully described.

.Mounted by :means of screwsor I other suitable means .upon' the under'surface atone end of the upper horizontal :member 4: of thewindow casing is a bearing plate 10 ;provided with a pair ofscrew receiving apertures 11 (Figured) 'to facilitate mountingof thepiate. The bearing plate '10 is also'provided with a bearing opening 12 to receive theupper hearing :pin or stud 13 which projects from :the upper end of a tube or sleeve 14which isintegrally formed byrolling oneimargin ofthe flange forming-a part of one-ofthe longitudinal members forming a part Ofan-outer channel cross-sectioned screen frame 15.

The improved-screen proper comprises the outer channel cross .sectioned :meta'l screen frame '15 and an inner channel :cross sectioned metal screen frame 16 which telescopes or fits into the outer screen fran'ie as indicated in Figures .6 and -9and stretches a wire screening'l 'l' tightly in position with the margins of the wire-screening clamped between the two interfitting screen : frames 15 and 16. Thetwo screen frames :16 and 15 are secured together by:means-.of;screws, bolts'or other suitable means.

Secured inithe lower end of the screen hinge tube 14 is a lower hinge pin ors'tud 18 which is .adaptedto :be engaged .inz'a'socketornpening 19 provided in a bearing 161001120. The bearing block 20 is slidably engaged in a guide channel 21 integrally formed -'on an angle bracketi22 secured :by means Lof screws 23 or other suitable means upon one end of the casement sill :5 as clearly illustrated in Figure "3. The bearingblock '20 isprovided with an opening v 24; for the reception :of a retaining :screw .25 to permit the bearing block when :in the position illustrated in Figure 3 to be screwed in place inthe guidechannel 21to afford a'bearin'g for the'lower pivot pin 18.

In mounting the improved screen in position the upper pivot pin 13 is first engaged in the bearing opening 12 of the plate '10 after-which the lower bearing block is anoved into the dotted line position illustrated in Figure 3 to permit the lower pivot pin 18 -to be engaged in the opening '19 of-the bearing block 20 after which said bearing block is moved into the full line position of Figure 3 and secured in place by means of the retaining screw 25. The improved screen is thus mounted in a hinge form in the window casement or frame with the outer screen frame 15 positioned to the outside of the window.

Shiftably mounted on the middle portion of one :.of 'thellongitudinal members 0f the inner screen frame 16 is a screen latching device comprising a plate 26 one longitudinal margin of which is bent outwardly at right .angles to afford a flange 27 the margin of which is bent at right angles to provide a latch flange .or .locking plate 28 adapted to be moved into'latching engagement with the slotted :frame plate '7. The ,-.guide or mounting plate 2610f :theflatch: device ;is provide with a pair of :inclined slots 29 ure 7) .through which a pair of :mounting screws3O project. .Integrally tformed-omthe upper .end -.of the mounting plate .26 of the latching device is aifingerpieceoranglememher-31 to facilitate-a :shifting operation of the latching device. When the latching device .is .in :the .full line position. illustrated in Figure .2 the latching plate .28 is :in released or unlockedposition as shown in .Figure 9 and is out of engagement with the slot 8-of the plate 7. .The .screen is thus permitted to be .swimg outwardly on .the pivot pins .13 and .18. When the screen .is moved vinto closed position 'vvithin the window ca-sing .it is adapted to be locked .in place by shifting the latching device by means of the finger piece 31 downwardly .into the dotted line Tpositionof Figure .2 thereby projecting the latching plate .28 into ltheslot .8 .of the ,plate -7 to 110111 the screen locked in position.

Figures v10 .and 1 1 of the "drawings illustrate a modified form of screen wherein .a wire screening 31 .is clamped in stretched position between .two intenfitting channel cross sectioned screen frames each of which is constructed .of. a ,pairof longitudinal channel .cross sectioned sills 32 and a -,pair of channel cross sectioned horizontal or vconnectingmembers 33. "The longitudinal .frame members 32 and the transverse frame .member's '33 are connected together by means of a pair of .interfitting channel .cross sectioned corner ,plates or unions .34 and 35. The .corner plates are providedwith integral tongues or lips '36 which are .bent .at right angles to the plates35 -and ,pro' 'ec't upwardly through slots or openings in the corner plates 34 and are "bent over to securlyfhold the corner plates '34 and 35 rigidly connected together "to 'form a corner for the screen frame.

It will of course be understood that many changes may be made and numerous details of construction maybe variedthrough=a'wide range without departing from the principles of this invention, and it istherefore not pur I30 posed limiting the patent granted hereon otherwise than necessitated by the prior art.
