9 Claims. (Cl. 20-71) This invention relates to window gratings for use upon houses and other buildings to prevent would-be intruders from entering through windows or other openings.

The present invention contemplates a construction whereby the grating bars may be securely locked in the windowy barring position when their protection is desired, and may be easily and quickly moved to an inactive position 1'0 adjacent the sides of the window, where they are more or less out of sight, when their protection is not wished.

One feature of the present invention resides in a window grating having guide strips or rails l5 secured to the window frame at the opposite ends of the grating bars to support them -for sliding movement to and from the window barring position,v and provided with a central guide rail secured across the window toslidably support 201 these bars between their ends, and also having means associated with the central guide rail to lock the grating bars to this rail to prevent the bars from being forced out of place.

A more speciiic feature of the present inven- 25 tion resides in the construction for locking the grating bars to the central guide rail to thereby retain these bars in the window barring position so that they cannot be sprung apart or moved y longitudinally or transversely of the guide rail. 30' A further featureresides in grating bars connected by braces to operate in sets and to brace one bar from another, and in means for supporting these sets for sliding movement and also for swinging movement about the axis of one bar so 'that the grating bars can be swung back away from the window adjacent Vthe wall of the building.

Other features of the invention and novel combination of parts in addition to the above will 59 be hereinafter described in connection with the accompanying drawings which illustrate good practical forms of the invention. f

Fig. 11 is a transverse sectional view through the bar supporting rails of Fig. 9.

Fig. 12 is a horizontal sectional view through l5 the window of Fig. 9 looking down upon the lower locking rail; and

Fig. 13 is a perspective sectional view of the lower locking rail. Y

The window grating of the present invention 0 may be. used in windows of the ordinary home or other buildings and may be readily installed in new or old windows where their protection is desired. The window frame which may be of usualV construction has the sides I0, top portion II and bottom portion or sill I2, and in the frame are slidably mounted the upper and lower sashes I3, both sashes being shown raised in Figs. 1, 9, and 10.

In the embodiment of the invention shown in Figs. 1 to 8, inclusive, the grating bars I4 are independently movable, and when their protection is not desired may be moved to the sides of the window, that is, two to each side of the window, where they are stored one against the other, out of the way and out of View from the outside o1v the window.Y The grating bars I4 may or may not be provided with heads atrboth ends and are shown as provided with heads I 5 at the upper ends but none at the lower ends. Y

These bars I4 are slidably supported at their opposite ends by guide strips or rails I6 and I1 which are channeled in the'constructionshown to slidably receive the upper heads I5 and lower ends of the bars I4. The upper rail I5 is shownV 45 as secured by screws I8 to the top portion II ofV the window and the lower rail Il is shown as secured by screws I9 tov the window sill I2. The upper rail I6 is provided with pockets 20 along its length adapted to receive the heads I5 to hold 50 the upper ends of the bars I4 in the window b-arring position, and the lower rail Il is provided Y with the pockets 2| adapted to receive the lower ends of the bars I4 and hold them in the window barring position. 55

1 mediate unslotted portion of the bar Ywill enter VthenotchV V23 4so that if the bars I4 are locked in this lowered position they will be held against f5`5 lowered position just mentioned comprisesV a Y cutting notches in these ribs as Yshown in Fig. 2.

The lower rail I1 is; shown as trough or U-shape in crosssection and the pockets 2| are formed by providing holesin the bottom of this rail to receive the ends of the bars I4. Y

-If the bars I4 are relatively long ably receive the intermediate portion of the bars I4 and lock'them in the window barring position.

The central rail 23 in the construction shownhas VVthe forni of a hollow tuberectangular in cross sectionand has formed in its upper and lower Walls theY longitudinally extending

slots

24 and 25 extending fromran unslotted central portion 26 of the rail to'near the ends of therail.- and Y permit the Ybars I4 to slidealong the slots 24 and V25 from a stored positionadjacent thesides o1 the window to the window barring position.

The central rail 23 in'the kconstruction shown serves Vto lock the bars in spaced relation kto each other and also to hold the ends of theseV bars'in Vthe pocketsiZIJ, 2|. shown as square in' cross section and as provided at their central Vportion with a transversev locking The grating bars I4 are slot 21 adapted to slide in the longitudinal upper slot'Y 24 Lof* the rail 23. Thelower longitudinal slot 25, it should be noted, is wider than the slot 24 and slidably receiveslthe Vunslotted portion of As a result of this construction the theV bar fI4. t vertical sliding movement of Ythe bars I4 is limited by the width ofthe slots 21.

Y In order to lock Vthe bars against sliding movementalong the slots 24 each of these slots isprovided with the -bar receivingnotches 28positioned to retain the bars in the window barring position.

The arrangement is such that when a bar I4 is movedrto its window barring position its Yends` will drop intothe Vpockets 20,`2I and an intermovement Vboth longitudinally and transversely. The means shownrfor locking each bar v I4 in the locking strip, 29 slidably mounted inthe hollow rail 23 for` movement into and out ofthe notches 21. Thisstrip may be shifted byakey controlled lock 30 to and from thebar locking position.` The lock 30 is .conveniently mounted in the solidportionf26 of the rail 23 and has a revolving barrel at the inner end of whichis secured an eccentric 3l adapted to coi-operate with projections 32 on Vthe strip 29 to shift this strip. Pins 33 mounted in the rail V23V and extending through. inclined slots A3l! in the strip 29 guide-this strip.along a diagonal path as it isshifte'd by the lock to move the strip from its bar locking position of Figs. 4

and 5 to its'bar Yreleasing position of Figs.f6, 7.' I e' and'S.

It will be seen from theforegoing that when the grating bars I4 are moved to the position in,

' "whichthey Vare shown in Fig. 1 and lowered into the proper pockets 20'and 2 I, they may be locked it is desirable Vto provide means for bracing or connecting'them`V Y between their ends to prevent the bars from being Vsprung out of place, and this is'accomplished the' construction shown in Figs. 1 to 8,1inclusive, byproviding the central'rail 23 adaptedto slid?r in this position by operating the lock 30 to move Y the strip 29 to the bar locking position. y Y Y In the modification shown in Figs. 9 to V13,

inclusive, the grating bars V` are connected by `the Ytransverse braces 36Y to Voperate Vin sets or 5 pairs so that one bar braces another to prevent the bars from being sprung out of place. yThe bars 35 are provided with heads 31 at their ends Y adapted to slide in the channeled guide rails 38 and 39.` The upper rail 38 may V.be constructed the same as theupper rail I6 above'describedand f is provided along its length'with' pockets similar Y tothe pockets 20 adapted to receive theheads 31VV to hold the bars in the windowbarring position. `The lower guide rail 39. has the rectangular shapeA in cross sectionbest shown in Figfll'rand in its upper face is formed a longitudinally ex- Vtending slot 40 in which the bars 35 slide. In

the lower wall of the channeled rail 39 are formed the, pockets 4I adapted to receive thev heads 31 20 when thebars are moved to the window .barring position and dropped in theV pockets of the upperV and lower'rails. Y The lower rail is shown as'havf ing a locking strip 42 and key controlled look-4,3 mounted in` a central Vunslotted portion ofthe rail 39,- similar to the strip;29`and lock 30 above described. The arrangement is such that the lock 43 maybe operated to moveth'e strip ]42 from its inactive positionV in which it is shown-ln Figs; 12 and 13 to its locking position of Fig. 11. In Fig. 11 it will be seen that the head'31 lies within the pocket 4I and the Vstrip 42 overlies a portion of the head Vto lock the bar heads in the kpockets in the upper andV lower guide rails to secure-the bars' Sincethebars 35 are connected to operate inV sets orY pairs they can not be stored one against the other atr theHsides of the Window as in thev construction of Fig. 1.l Fig. 12Y therefore shows'a construction whereby the rigidly connected bars 40 Vafter being moved tothe sides of the window mayV be swungrabout the axis of one bar outwardly away from the window sashes to a stored posi-,-V tion adjacent the inner wall of the room as will in the window barring position.
