part of this specification.

' This invention relates to window guards and consists of the matters hereinafter described and more particularly pointed out in the appended claims.

The object of the invention is to provide a guard for windows which may be readily and easily attached to a window and its associated casing, or which may be detached therefromby one within the room in whichv the window is'located when the window is closed, but which is securely locked in a position of security and safety when the window is open, no mater how small the opening," so that it cannot be removed either from a position inside or from a position outside of the window.

In the drawings :Figure l is a view in elevation as looked at from the inside of a building, of a window casingor frame with the usual upper and lower window sashes thereof in a closed position, and with my improved window guard attached in proper position. Fig. 2 is a fragmentary view of the same in elevation on an enlarged scale villustrating the position the guard assumes when the lower window sash is in a raised position. Fig. 3 is a detail vertical section on an enlarged scale, the plane of the section being indicated byline 3-3 'of Fig. 2. Fig. 4'isa' detail perspective view of 'theupper left-handcorner of the lower window sash and its surroundings showing a part of the-window guard, attached thereto, Fig. 5' is a detail perspective view of a channel which forms part of the attaching means forthe window guard. Fig. 6 is a view in. perspective of the guard as it appears when detached from the window. Fig. 7 is a detail .plan sectional view, the plane of the section being indicated by line 77 of Fig. 4. Fig. 8 represents a view similar to that shown in Fig. 7 with the parts in {changed relation.

Referring now in detail to that embodi-.

ment of my invention illustrated in the accompanying drawings, 10 indicates a window casing or frame, and 11 the usual horizontal sill member forming a part thereof. The said casing is provided with the usual upper and lower sash members 12 and 13 which are adapted for vertioal'sliding move-' ment insuitable guides or runways forming a part of said casing. v

14, 14 indicate vertically arranged channel members which are attached to the inner faces of the upright side members 13*, -13 of the lower window sash 13. Each of said channels 14, 14, are of a length approximating the vertical height of the upright member 13 13 of the window sash 13 and consists of a body member 14 of U-shape incrosssection and having laterally extending flanges 14", 14 which engagewith the sash members 13 15 and by means of which said channels 14, 14, are fixed to said sash members. Each, body member 14 is provided with a slot 15 which extends approximately from top to bottom of said. members, is closed at both ends and has an enlarged hole 15 at its upper end.

16, 16 indicate anchor plates fixed to the window sill 11. Said platesv are arranged to cover laterally spaced recesses 17 formed in said sill, at a suitable distance from the plane of the lower sash 13. Said plates extend a short distance beyond the lateral edges of the recess 17 and are attached to said sill by means of screws "16 the'upper surfaces of said plates being preferably made flush with the upper surface Ofsaid sill member 11. Each of said plates 16 has an aperture 16 the purpose ofwhich will appear as I proceed withmy specification.

"20' indicates as a whole my improved window guard (see Fig. 6) which is of a height aiidwidth approximating the height-and width of the lower window sash 13. :Said

guard has-an open frame which comprises,

as shown, upright side members 21, 21 and top and bottom horizontal membersx22, 23.

The frame is closed by a grating for other like device which is capable of freelyadmitting lightand air while at the same time preventing the passage through the frame of persons or children from the inside or of burglars or thieves from the. outside.

In the drawings the frame 20 is shown as beingclosed by a grating made-of upright laterally spaced bars 241 which are attached at their ends "to the topand bottom hori ber25 is preferably so arranged as to bind zontal members 22, 23 of the frame 20. To strengthen and brace the frame as a whole, a centrally disposed horizontal bar or memthe side members 21, 21 and the upright spaced bars 24 together. The WlIlCl-OW guard is removably attached to the window sill .11 and to the lower sash member 13 in such a way that the lower sash may be raised freely a' s desired and when said sash is in raised position, the security of the guard is assured against removal either frominside or from outside the window. The preferred way of attaching said guard '20 is as follows: The bottom frame member 23 of the window guard is provided with depending, inwardly projecting, hook members 26. As

shown in the drawings, the said hook mem bers are'formed by extending the lower ends of two of the grating bars 24 below the horizontal bottom frame member 23 and bending the same inwardly to form hooks 26, 26', as illustrated'in Fig. 6. The "said hook members .26 are adapted to be inserted into the apertures '16 formed in the anchorplatesfl 6,-fixed to the sill 11, so that when the window-guard 20 is swung into an upright position, the said hooks lie within the recesses 17 formed in the sill 11. Said hooks are made long enough so that when the guard rests upon the window sill, the'hooked ends there-of will rest somewhat below the anchor plates '16. The upper ends of the upright'side frame members 21, 21 extend beyond the upper surface of the horizontal "top frame member 22 and are bent in a direction opposite'to thatof the hook membore 26 to, form outwardly extending horizontal'hook members 27, 27. Each hook member 27'is reduced in diameter near its free end to form a neck 28- and when said frame isin an upright operative position said heck 28 operatively engages within and has sliding bearing between the walls defining the lateral edges of the slot 15 formed i i-the channel member 14..

The'window guard :20 is attached to a window sin-provided with the anchor-plates a window sash provided with the .channels 14, 14:, in thefollowing manner.

f'fllhe lower window sash 1'3must'be inits closed position and the frame 20" is then held in-front of said sash with its upper-end 'in'cliinedl-toward the interior of the room. The-bottom frame member 23 'is then moved tobrirrg its inner edgeintoj'engagement with -th'e rinner "margin :of the anchor-plates 16 (see-Fig; 3) and when inthis position the 1 .ihook-me'mb'e rs 26 are inserted into the apertures 16 er said anchor-plates '16,. The frameis then swung about the inner edge aof the bottom frame member 523 as an axis,

into a vertical position which movement Lhnin'gs the hooks 26, 26within the recesses 17 mama-a1. :tlreawindow sill Jill. ..The;tframeplate 16. 1

' lVhen 1t is desired toraisethe lower sash v 1.0

is-then' in a position permitting a slightplay in a vertical direction but cannot be withdrawn in that manner. When in a vertical position the bottom frame member 23 completely covers the plates 16, 16 in the sill.

Vith the window guard in this position'the ends of the hook members 27, 27, engage that portion of the body member 14 of the channel members 1 1 defining the lateral edges of the slots 15 adjacent the enlargements l5- at the upper ends thereof. When in thisposition the said hook members cannot be inserted into the interior ofthe'channel 141-. The window guard is now slightly raised the engagement of the hooks 26 with the anchor plate 16 permitting such movement) until the outer end of'th'e hooks 27 with the enlargements 15 of the slots 15- and the frame is then swung about-its lower edge as an axis when the hooks 26 may be disengaged from the apertures in the 13. with the window guard 20 in place, said guard in no manner interferes therewith.

The sash in rising carries with it its asso . ciated channels 14, 14 which channels will end hook members 27 so-that the guard ca n not be withdrawn or removed when'the sash is raised. Y It is apparent that a window guard-made always be in position to. guide and hold the; a A

in accordance with my invention can be'readi l-y and easily attached to or detached from the window sash and casing by a person from within the room and cannot be removed from the outside. :This: is. advantageous inasmuch as the housewife can quickly' detach V the window guard for the purposeof-washing. windows or the like and replace the 'same'when ready, without the necessity of Imanipulating catches, springs, or other do VlCGS, the operatlon of which she may not be familiar with. The guard rests cl oseto the window sash,is not int'he way for thev window curtains anddoes not present -an" unslghtly appearance from the outside. The

guard is always in a position of securityand safety no matter how far the sash is' ra'i'sed andthe only time that said guard can-be re- I *moved from the window to whidh it is attached 31S when said window isclosed.

While in describing my inventiom-fl referred toicertam details of mechanical eonstruction and arrangement, it is to be understood that the invention is not limited there to, except as may be pointed out in the appended claims.

I claim as my invention:

1. A window guard adapted to be secured at the inside of a window cdmprising in combination with the window sill and the lower window sash, an" open frame, a covering for the said frame, means for detachably engaging the bottom of said framewith said window sill, vertically extending guide members on said Window sash, and devices at or near the upper end of said frame adapted for locking and guiding engagement with said guide members.

2. A window guard adapted tobe secured at the inside of a window comprising in combination with the window sill and the lower Window sash, an open frame, a grating covering said frame, apertured plates fixed to said window sill, the said window sill being provided with recesses below said plates, means provided at the bottom of said frame for engagement in the apertures of said plates, vertically extending slotted channel bars fixed to said sash, the slots in said channel bars being closed at their upper ends and being enlarged at said upper ends, and devices provided at the top of said guard frame adapted for insertion through the enlarged upper ends of said slots and for locking and guiding engagement Within said slots when said window sash is raised.

In testimony that I claim the foregoing as my inventionI affix my signature in the presence of two witnesses, this 7th day of April A. D. 1914. I s
