7 Claims.

This invention relates to window gratings adapted for use to prevent intruders from entering through windows, and it pertains more particularly to a construction in which the bars forming the grating may be readily moved to and removed from the window barring position.

It frequently happens that the occupants of a home or other building may wish to leave the to windows open but hesitate to do so for fear that an intruder will enter through an open window. To prevent this bars may be provided across the window but most people object to barred windows as unsightly in appearance.

The present invention therefore contemplates a construction in which the window bars may be stored in housings at the sides or top and bottom of the window out of sight when not in use, and may be readily moved to the window go barring position when their protection is desired.

One important feature of the invention resides in means for supporting the bars of a window grating for sliding movement from the window barring position to a stored position at one or both sides of the window or at the top and bottom thereof, and in means for locking the bars in the window barring position.

Another important feature resides in a bar o. receiving housing at one or both sides or a window and in bar supporting guides adjacent the housing and adapted to support the bars for sliding movement from the window barring position to a stored position in the housing. A further feature 01 the invention resides in supporting guides adapted to slidably receive the loads of the bars and provided with spaem pockets along their length to receive said heads and hold the bars .in the window position, and in key controlled or other means ior locmng the heads in said pockets.

@ther features of the invention and novel combination oi parts in addition to the above will he hereinafter-"described in connection with 4gp the accompanying thawing which illustrates one good practical dorm oi the invention.

The window grating of the present invention may be used in the windows of the ordinary home or other building and may be readily installed in windows of various shapes and sizes. The window frame shown, which may be of the usual construction, has the sides 10, top portion 11, and sill or bottom portion 12, and in this frame are slidably mounted the upper sash 13 and lower sash 14. I

The window grating of the present invention is formed of the independently movable bars 15 that are mounted for sliding movement from the window barring position of Fig. 1 to their so concealed or stored position of Fig. 2. These bars are shown as provided with heads 16 at their opposite ends adapted to slide in an upper guide rail 17 and lower guide rail 18, and each guide rail is preferably given the hollow chans5 neled construction shown adapted to slidably embrace the heads.

These guide rails are conveniently made of sheet metal and the upper rail 17 is formed with the spaced upwardly bent edges or ribs 19 having the bar receiving slot 20 between them. The heads 16 may slide upon the ribs 19 as the bars 15 are moved along the guide 17, and in order to retain these bars in the desired spaced relation" to each other the head-receiving notches 21 are formed at intervals along the guide rail so that the heads may drop in these notches.

The lower guide rail 18 has the channeled construction best shown in Fig. 3 and the edge portions of the metal strip forming the channel 18 are spaced from each other to provide the bar receiving slot 22. The guide rail 18 in the constructicn shown is provided at intervals along its length. with the rectangular holes 23 formed in the lower wall of the channeled rail 18 to receive the correspondingly shaped heads 16. The arrangement is such that when a bar 15 is moved along the guide rails 1'7 and 18 to the desired position the upper head 16 will drop into a notch 21 and the lower head 16 will drop into a hole 23, to hold the bars in the desired spaced relation to each other.

The bars may be readily locked in the position just mentioned by holding the lower 5 heads 16 so that they can not be raised out of the holes 23. This is accomplished in the construction shown by providing the locking strip 24 which normally lies inactive within the hollow guide rail 18 at one side of the row of holes 23 as shown in Figs. 4 and 7, and when it is desired to lock the bars in the window barring position it is simply necessary to shift the strip 24 in the channel 18 to a position in which it overlies the heads 16 as shown in Fig. 8-. 'Ine strip 24 may be readily shifted from its inactive position to its active position by providing it with an operating pin or knob 25 that projects upwardly through a diagonal slot 26 formed in the upper wall or the rail 18.. The strip 2c is preferably also provided with the inclined surfaces 27 and 28 formed at the opposite edges of the bar and adapted to oo-operate with guide pins 29 and 30, respectively, rigidly secured in the guide rail 18.

The arrangement is such that when the strip 24 is moved in the direction of its length by the knob 25 it will be guided in a diagonal or lateral direction by the engagement of the inclined surfaces 27 or 28 with the fixed pins 29 or so. The strip 24 may be locked in its bar securing position of Fig. 8 by a key controlled lock 31 secured to the strip 24 and provided with a key actuated bolt 32 positioned to co-operate with a fixed pin 29. The key for the lock inserted through ahole 33 in the upper wall of the guide 18. As long as the lower head of a bolt 15 is held locked in a hole 23 the bolt can not be raised to release its upper end from the corresponding notch 21.

While the mechanism just described constitutes one simple and practical form of means for locking the bars in the window barring position other means to this end may be employed. The locking means may be key or otherwise controlled, and may co-ozoerate with either the upper or lower guide rail or with both of these .rails as desired.

The guide rail stock 1? and 18 may be supplied in any desired length so that it may he cut during the operation oi installing a guide rail to conform to the width of the window frame to which it is to be secured, and the upper rail 17 is secured to the top portion of the window Irame by screws 3% while the lower rail 18 is similarly secured to the wondow sill 12.

When the bars 15 are not desired in the window barring position oi l, the loo-Eng strip 24 is unlocked and shifted to its inoperative position of Fig. 4 so that the bars may be lifted the guide rails to the stored position at each side of the window. It is desirable to conceal the bars while they are stored at the sides-oi the window and this is accomplished in aceord= ance with the present invention by providing at each side of the window a bar receiving housing 35 which may he formed on sheet metal and given the U-shape in cross-section best in Fig. 4. The housing 35 may be out to the desired length to extend from the upper rail i? to the lower rail 18 and secured to the window frame by screws 36. The construction iii trated is such that the entire crating including its supporting rails and housings lies within the oonnneeoithewindowiramesoasnottom out oi the recemes 21 and 23 and moved along heads and support the here for sliding;

mosses trude beyond the inner face of this frame, and presents a neat appearance.

While in the construction and described the bars 15 extend vertically of the window and are stored in the housings 35 at the sides thereof, the guide rails 17 and 18 may if desired be mounted at the opposite sides ot'the window to support the bars in a horizontal position and the housings 35 may he provided at one or both ends of the windows.

It will be seen from the foregoing that guide rails 17 and 18 and housings 35 may Le readily cut to fit any window and secured in place by the screws 34 and 36. The bars 15 may be cut to the required length and the heads 16 may be riveted or otherwise secured be installed in windows of a definite size the parts i7, 18 and 85 may be and secured together at the factory rectangle frame adapted to it the frame and be secured thereto inside of ing sashes.

When a window is equipped with the are of the present invention the Window may be wide open either in the day time or ni without the danger or an intruder ente through the. open window.
