TIhe presentinventionrelatesto window .clo .sures and the "like, andiattempts to overcome ;.the' trouble experienced with the general type now used. It has been comparatively easy .to

gain entre to a building due to'the frail and flimsy, closures that have been used; In addition, Screensthat are now being used are, as arule; so' 'weaklyattached that the can be pushed outwith little exertion. As .a result, there have beennum'erous kidnappings, petty thievery, and numerous instances of small children falling out of the window because of these weakly constructed closures and poorly attached screens. I important object of my device is to prevent children from falling [out of the .windows of dwellings where only a screen is used to preventsuch happenlings 'by securely attaching the screens to- ,a window barrier.

Another object of this invention is to secure the barrier and screen to the upper sash of the window, This type of a barrier would bemost applicable in institutionswhere a great deal of difficulty is experienced in preventing patients from escaping through the windows.

Still another object of .this invention is to prevent the removal of the barrier and the screen from the inside orout without the use of a'key to operate the '19Ck 'WhlCh secures the unit to the window. I v

A still "further Lob'ject of ,rny invention is to permit the uppersash to be lowered to a pereeptible degree without removing the barrier frame. L

A still further object of -my invention is to provide means for completely covering the locking-constructionso as to render it difi'icult to be {manipulated without the use of a key.

Another object of 'my invention-is to'provide the grille frame out of a "blank which is bent upon itself to form a rectangular'frame for the o'penwork grille and to securely lock the grille to the frame. Y It is also an'obje'ct of the invention to provide'a barrier of the above indicated character, which is simple and substantial in construction, which can be manufactured economically and which will be thoroughly efficient and practical in Qus,

With these and various other objects in View, the invention may consist of certain novel features of construction and operation as will be more .fully describedand.particularlypointed out in. ;the,;specification, drawings and. laims. appendedzhereto. r HInethe ,clrawin ,'-which illustra e an embodi- Fig. 3 is a fragmenta (shown inFig. 5.

'Ifhe barrier frame 16 is provided with open grillework {18. and has integrally secured theretof'a screen 20.

The top edge of theirame 16 is providedwith two inwardlyextending lugs 22 which are slotted at 24 andadapted .to slidably engage the guides .26 which aresecured to the upper isash 1 2 as .will belater described. I I

In order to attach the upper guide 2;; to .the upper sash l2, threaded bolts 28 are inserted through the openings 30 in the flanged portion of the guide 26, .and then through the s maller openin 32 i heup r sa h 2 an has cu d .to'its ends, a washer 34 which isflattenedimorder -to prevent :the bolt 32 from being unscrewed.

The large opening 36 in the-uppersash v12 is-then .filled with cement 38 flush to the insideof the w ndowand-sa h Fli an ed owe po tion 4(l-isattachedgto the lowerend of thewindow sash 1 n kkno n mann iasa 1- Attached to the bottomand center of the-harbolt.

rier frame 16 is a lug 42 which is secured to the sill in the following manner. A casing 44 is inserted into the opening 46 of the window sill and any well known lock 48 having a retractable bifurcated member 50 is then securely attached to the casing (not shown). A plate 52 having vertical spacing members which rest upon the top of the casing 44 is then secured to the casing 44 asaat 56. A cover plate 58 is then placed over the parts and secured to the window sill as at 60. The barrier and screen unit are then swung into place, the aperture in the lug 42 being directly over the aperture 62 in the cover plate. A threaded bolt 64 having a reduced portion 66 is then inserted into the lug and cover plate apertures and threaded in the aperture 68in the plate 52 until the lug 42is clamped securely. The key '70 is then turned to'operate the bifurcated member 50 which engages the reduced portion 66 and prevents the unthreading of the Referring to Figure 3, I have provided a closure strip 71, which is attached along the bottom of the upper sash 12 and between the guides 26 so as to prevent moisture or dust falling through 'thes'p'ace between the upper sash 12 and thebarrier'framelfi and screen 20. v

The barrier frame 16 consists of a U-shaped channel of steel or other suitable metal, the sides of which are so notched at suitable intervals that the channel may be bent to form a rectangle. The bitter ends 29' and 29 meet at the point 29-and are joined by inserting a suitable spacer 31 and securing the same in any well known "manner as by rivets 33 or by spot welding.

In Figure 6,1 have illustrated the manner in whichfthe grille 18 may be attached to the bar- "ri'er frame 16. Since the extreme outside dimension of the grille coincides with the inside dimension of the barrier frame, the grille is held immovable within the frame when the open end is closed. 1

Referring to Figure 11, the channel is then In Figure 8, I have shown the manner in which the guide lug is attached to the barrier frame which consist in inserting the guide lug 22 into an opening 23 in the barrier frame 16. A spacer 2 5, of approximately the same area as the guide lug 22, is then inserted and then the spacer 25 and the lug .22 are secured to the walls of the 'channel in any well known manner as by rivets '27 or by spot welding.

In Figure 7 I have shown a modification of the locking means which consists of a casing '72 which is secured to the window sill as at 74 and adapted toreceive the threaded bolt 7 6. The bolt 76 is bored to receive the locking member 78 operable by the key 80. When the key is turned the lugs 82 move in the opening 84 and. engage the'under surface of the casing 72 and prevent the removal of the threaded bolt 76. The lug 84 is adapted to be secured to the sill by the nut 86 of the bolt '76 and is similar to the lug 42 shown in the preferred form except that it functions as a cover plate as well and completely covers the locking parts. In Figure 10 I have shown another modification of the locking means which consists of a casing 45 which is secured to the sill (not shown) and adapted to receive a lock 58 which is secured to the casing (not shown).

I have shown a plate 53 having vertical spac ing members which is similar to plate 52 in my preferred form and is secured to the casing 45 and the window as at 55.

The retractable bifurcated member 50 is adapted to engage the reduced portion 88 of a bolt 90. The bolt 90 is securely attached to the bottom of the barrier frame 16.

I have provided a cover plate 58 which is attached to the sill as at 60 and-has a cut out portion 59 which allows the bolt 90 to drop into position and become locked by the member 50.

I have also provided another cover plate 57 which is likewise attached to the barrier frame and adapted, when the frame is swung into position, to completely cover all the locking parts from view in the front.
