rlhis invention relates tov an improvementV in a Window screen, and more particularly in a screen of the metallic frame type and in the details of construction of the screen '5 frame.

Thelprimary Object of this invention is to providein a screen having a metallic frame madeup ofside, top andy bottom rails meet- Y v,ing-at ythe corners a mit-er joint, means for supporting andrigidly uniting the abutting-,ends of therrails in order t0 resist any tendency lto spread at fthe corners.

A further object of this invention LAis to provide in the screen rkof the character above described7 a corner piece Which will function'bothto hold the rails. in their proper position j and also to Vclamp the ylocking mechanism of the frame firmly in place in the'cross'rail.

Another obj ectv of this invention-iste provide a cornerpiece made up' ofa channeled strip lof metal bent at right angles, the

inner yline of the angle remaining contin.

nous and-unbroken.

Y Another obj-ect ofthi-s invention is Vto provide in 4a-screenf'having'in thecross rail,

Z0 Referring to the dravvings,the referencey numerallO is employed to Vvdesignate a portion'ofra Window screen frameernbody-ing onevform of the invention includinga cross' railll and arsiderail 12, Awhich meet in 4a '15 miter joint 13.

Referring ,particularly to Figure '6,-'

"it Will be ynoted that 'the corner piece '16 is a single plate'bent atl its sidesfto forma -channel v*19,.an'd bent Aat right angles at'ZO.y c5v j nerpieces previously Inade'this portion. of pear lf-roina consideration 1 ofthe following Y 40;"description'taken yinconnection with` thethe 'angle ,is open. -1'I`his vcontinuous cons of the corner piece 16,'assh0vvn in Figure/6,

differ in depth',l vrfor a purpose VYIvvhi'ch v vill bedescribedlater. Y Y Mounted yinlthe-chamber ofthe-cross rail 11 is yalockingmechanism21; which comprises'ia .bar 22 terminatingV init lpin' 'f managing STL i or apertures 29, through which the prongs 28 are passed when the parts are assembled. Y

which tends to 'hold the locking pin 23 projecting through an aperture in the side rail 12 to engage in holes in the window frame (not shown). At the inner end ot the bar 22 is secured a handle 26 which eX- tends through a suitably formed slot 27 in the cross rail into thechamber 1a.` At the Vupper end of the handle 26 are formed separated prongs or projections 28, and in the inner end of the bar 22 are provided slots Referring particularly to Figure 2, it will be noted that a portion ot the top rail is cut away to provide an opening 30 to the chamber lll. At each end or" thev opening 30 is provided a support 31, on which rests the ends of a cap 32, bywhich the opening 30 is normally closed. VVReferring to ures 2 vand o, it will be noted that the inner end oi the rod 22 terminates below the openp the prongs 28 are bent toward each other,

as shown particularly in Figure2, and the parts are rthus quickly locked together.

' The' end of theV handle 26projecting below the cross rail yis bent to provide a finger grip. The handle bears on the :front edge of the slot 27 as a iiulcrum when pressureA is appliedto the' gripv to retract the pin 23. The inner wall of the groove 15 is bent outwardly at 33 to perinitthe free movement of the handle;Y 4

The casing 24 of' the loclringdevicehas Y a cylindrical portion :311 to receive the pin 23 and the spring 25, and a iin 35 projecting downwardly from the portion 34, as shown in Figures 2and 4. l/Vhen the corner piece 16is inserted into theV chamber 140i the crossrail, the walls 36 of the shallower armVv 20 extend `at either side of the iin` 35 Vand bear'against the cylindrical .portion 34E, thus f insuring the rigid location of the locking means in the chamber 14.V The arm y19is Y .inserted into the chambervll ofthe side rail 12, and. is preferably of' substantially theV same sitze as the chamber, so that there is no relative `movement between the two. p

In order' to supplement the'action of the corner piece 16 thereisprovideda fasten' ing clip 37 having tips 38 which enter Vslots 39in the side 'andVV cross 'rails adjacent the corner. The ends of the tips 38are bent toward fthe joint, as shown particularly in Figure 1, and thus the clipsV 37 assist the corner piece tohold they rails at the joint vided. y .at a corner where theie'is no loclring mecha-v nism, the arms would be of the size of the and to resist any tendency of the joint to spread.

The corner piece 16 is shown and described as having its arms 17 and 18 of different depths, so that it can bejused ata corner where a locking mechanism is prolVhen the corner piece is to be used chambers, so that there would be noV relative movement between the arms and theY rails. f

- TWhile certain embodiments of this invention have been shown and described, applicant is not limited thereto, since it is obvious that other embodiments can be mader without departing froin'the spirit and scope ot this invention as set forth in the followi ing claims.

Having thus set forth my'invention what l claim as new and for which I desire protection by Letters Patent is: 1. In a screen having a metallic frame niade up ot a side and a cross rail meeting at the corner ina joint, a corner piece made upV ot a channeled strip of metal bent at right angle, the inner line of the angle remaining continuous and unbroken, said corner piece rspanning said joint and resisting anyrtendency for the frame to spread at the corner. y

2. In a screen having a metallic frame made up orP a side and a cross rail meeting at the/corner in a joint,each of saidfrails having a hollow longitudinal chamber, a

ofnietal bent atright angle, the inner line of the angle remaining continuous and unbroken, one arm of said corner piece beingf Y inserted in the chamber of one rail and the other 'arm being inserted in the chamber of the other rail, wherebyV said cornerk p iece spans said joint and resists any tendency.

of the frame f` to spread at the corner, the edges of one arm being adapted to serve as a support for a screen locking mechanism.

3. ln` a screen having a metallic frame Y made up of` a side and a` cross rail-.meeting at thecorner inxa miter joint, eachoit` said rails'having a hollow longitudinal chamber a locking mechanism in thechamber of said cross rail, and a cornerpiece bentat right angle inserted in the-chambers ot the ad- Vjoining side andr crossrailsspanningsaid miter joint, the portion otsaidV corner piece in `said cross rail bearing againstV and4 posi-.-v

tioning said lockingmechanism.V Y Y v Y 4.' `In a screen having metallic 'trame made Vup of. a side and a cross rail-meeting s at the corner in amiter joint, each ofsfaidV rails having a hollow longitudinal charn ber, a, locking mechanism inz'the chamber of said'crossvrail', said locling vdevice including casing,v and .a `corner'piece bent at right angles inserted inthe chambers;V or

`iso s ico corner piece made uproi a channeled strip v Y Y the adjoining side-and cross rails spanning said miter joint, the portion of said corner piece in said cross rail bearing against said casing, and positioning said locking mechamsm. 1

5. In a screen having a metallic frame made up of a side and a cross rail meeting at the corner in a miter joint, said cross rail having a hollow longitudinal chamber, and an opening through the top of said rail, a locking mechanism in said chamber including a reciprocatory bar the inner end of which is below said opening and lhas a plurality of apertures and a handle in said cross rail terminating in prongs which are passed through said apertures when said parts are assembled and bent over, thus uniting said handle to said bar.

6. In a screen having a metallic frame made up of a side and a cross rail meeting at the corner, each of said rails having a holv low longitudinal chamber and a slot adjacent said corner, a corner piece made up of a channeled strip of metal bent at rightv anglejthe inner line of the angle remaining continuous and unbroken, one arm of said corner piece being inserted in the chamber of one rail and the other arm being inserted in the chamber of the other rail, whereby said corner piece spans said joint and resists any tendency of the frame to spread at the corners7 and a right-angled clip secured to said frame at the inner face of said corner by means of integral tips which enter said slots and are bent down toward the corner, thus supplementing the action of said corner piece.

In testimony whereof I have affixed my signature.
