WINDOW GRATING Application mea August 2, 1,927. serial No.. aiaol.

This invention4 relates to window gratings. One object of this invention is to provide an imp-roved grating for awindow or door, having removable bars held in place by a locking mechanismthat anchors and reinforces the bars against any possible spreading-,as by the use of ya jimmy, crow-bar, or the like.

A further lobject of this invention is to provide a grating of the character set 'forth having individually' removable bars and means to lock the bars in place and reinforcingly connect them together, so that the sawing oi abar or part ofthe locking means may 1-5 be insufficient to a-iord entrance through .the


g Still a `further' object of this invention is to lprovide a grating that can be rapidly rassembled or ydisassembled and comprises an improved locking device `formed4 of 'few and simple partshthat coact to form a neat con.- struction which is rugged and eiicient toa high degree in use.

@ther objects of this invention will in part be obviousr and. in part hereinafter pointed out.

.'fhewinvention accordingly consists in the features of construction, combinations of elements, and arrangement of `parts which will be eXem-pliiied in the construction hereinafter described7 and of which the scope .of application will be indicated in the following claimsthe accompanying drawing, in which is shownfone of the various possible illustrative embodiments vof this invention,

Referring in detail to the drawingsyfl() denotes a grating embodying the invention, shown applied on the interior side of any suitable frame 11 about any opening to be guarded,` as, for instance, window 11a.` Said grating includes a pluarlity of vertical bars 1.2 removably supported upon the base sec- 'tion 1.4 of casing A and retained in vertical position .by being received at their vupper ends in the bracket 13', the bracket' 13 and base section 14 being secured to frame' 11 .by any suitable fastening `means15. rlhe fastening means 15 securing bracket 13 to frame 1'1 are positioned as shown in Figs. 1, 2`,`and 6', so that they are linaccessible when 'bars12 are supported in the grating.

The casing A is made'up of thebase section 14 and the cover section 16, the latter being removably received uponl the former to retain the rods locked in position with respect to frame' The base section 14is of angular cross-section Iand is provided with "end walls 17 preferably for med integral therewith. Formed in vthe horizontal portion 14a of base section 14 are the recesses 2O intowh-ich the pins 19 formed on bars 12 are receivable. End walls 17 and the vertical portion 14b`of base section 14 are provided with a flanged edge por-tion 146 providing a shoulderl 14d 'upon which the edges ofcover section 16 are adapted to ybe supported. End walls 17 are provided with grooves 27 and horiz'ontalpor'- tion 14a isprovided with an opening 23 adapted to cooperate with parts on cover section 16 in the hereinafter described manner.

Cover sectionk 16 is of across-section simii lar to that of base section 14, the vertical portion 16a thereof being provided with a tongue i' 22 positioned for reception through opening preferably integral therewith. Said ribs are slidablyl received in grooves 27 when cover section 16 is positioned and serve to restrain said section from any horizontal movement, lThe tongue 22 has formed therein the perforation through which, when tongue 22 has beenpassed through opening 23, a lock 24 may be engaged to preventany vert-ical movement of section 16. lVhen cover section 16 has been positioned on base section 14, a box-like structureis produced."

Bars 12, at their lower ends, are provided with the collars 18 positioned above pins l19 andV fixed to bars 12 in any suitable manner. Pins 19 may be of thev saine thicknessasbars 12 or, as shown here, preferably of a reduced diameter form-ed by undercutting the end of said bar. L

Cover 16 is cut away or otherwise formed to provide the notches 21 which are of'suflicient width to pass around the bars 12 easily, but of insuiiicient width to permit passage of` collars 18. i' When bars 12 have been properly arranged with pins 19 received in recesses 20, cover section 16 may be positioned over base section 14 with notches 21 receiving bars 12, the under surface 'of the horizontal portion 16b being ,then in engagement with the upper surface of collars 18 and also restingon shoulder 14d. At the same time, ribs 26 and tongue 22 are received in grooves 27 and opening 23 respec- To provide for reinforcing the bar structure against sidewise strain or deflection, in case an 4unwarranted attempt be made to enlarge the opening, across member 28, made of -a flat strip of metal or the like ris provided,

located preferably on the interior side of the Vgrating and mounted on said bars inaparf ticular manner to permit reinovaltherefroin only under certain predetermined circumstances. Bars 12 are provided with pins 29 extending laterally from said,baispreferably at themid-sections thereof, said pins being provided with heads 29,a for the purposeherle- `ina'fterappearingl Said cross member is formed with a group of notches 30 along its upper edge,'the opening of said notches pointe img upwardly, whileanother group of notches Y31, out or formedin the lower edge of crossmember 28 has the openings thereof pointing downwardly.` It is lto be understood that these notches need not be grouped in any par- 'Nticular manner on cross member 28, vnor is ,there any necessary number relation involved in their mounting. A single notch 30 will effectively cooperate with a plurality.V of

nnotches 31 and with the bars 12 to produce the 12. Notches-30, 31 are made of considerable depth to provide greater security against disengagement of pins 29 from member 28. The bracket 13, of angular cross-section, is

-provided in the horizontal portion 13ZL thereof with through holes 32 positioned to align with a notch 30er 31, a notch 21,and a'recess 2U.

c The assembly and manner of use of the d evice is easily madeapparent from the ,following: @ner end of each bar 12 is passed upward through a'hole 32 in the bracket 13 and then pin 19 of said bar is seated inv recess 2O of casing A; *For a more efficient assembly, bars 12 to be associated with notches 31 are first positioned in the gratingwith their pins 29 'positioned for reception rinnotches 31. Bars 12 to be associatedwith'notches 30 are iiiountedviii a manner similar-to the other bars, but with their pins 29 rotated to one side,

as shown in Fig. 6. Cross-member'28'is now mounted on bars 12 with the respective pins 29 engaging the notches 31. By slightly lifting the bars 12 having `pins 29 to engage notches 30 sothat said pins are raised above l the upper edgeof cross-ineinber 28, the bar 12 may be rotated so that said pin will be in alignment with, and if allowed to fall, will slide into notch 30.

After the bars have been thus arranged,

cover member 16 inaybepositioned with notches 21 engaging bars 12v and collars-18` engaged by said member to retain bars 12in a locked position upon engaging lock 24 with tongue 2 2. v

lt, ofcourse, is understood that, if any ,of'bais 12 are to be'reinoved jfor any particular purpose, the'Y reverse operation Amust be carried'out. l' f Besides possessing the advantage of perL mitting the. removal of any bar, as may be 4 desired, said grating has'eXcellent-burglar proof qualities in that the-sawing of any of the bars or cross member, at any-point 'does not result in any disengagement ofthe grating parts'. y Moreover, `the grating'is of simple iiiaiiufactr-.rel adapted for heavy and strong construction.

In Figs. 7 to 9 is illustrated the improved i grating provided with a modified means vfor locking the cover section 116 Ato base section l 114 in which plunger lock 33 is incorporated'. Said plunger lock, preferablykmounted interiorly of cover 116 aiidcentrally on the horizontal portion 116b thereof, is provided atan end thereof with a pluralityofunL i tegral' fingers 33a to engage detachably in recesses 34ai of a hub 34. Hub 34, which is rotatably mounted on any suitable pivot means as, for instance, machine screw 35, rigidly secured to horizontal wall 114" of base section 114, is provided with arms 36 and 37 made integral therewith, or in any other manner secured thereto. Said arms extend outwardly from said hub into openings 40 provided in bolts 38, 39, with which said arms are adapted to have sliding and pivotal connection. Said bolts rest on the base section 114a of the casing, being slidably mounted at opposite sides of said section in guides 41, and movable in opposite directions upon actuation of arms 36 and 37. When the bolts are projected, they engage with recesses 42 cut in lugs 43 and 44, the former of which comprises an inwardly extending edge portion 116c on the vertical wall 116a of cover section 116, while the latter is provided by an arm 116d extending down from the horizontal portion 116'D of said section. Both lugs 43 and 44 are at the ends of said cover section and in conjunction with the ribs and grooves 127, ensure^ rigid connection of the cover section to the base section.

In Figs. 10 and 11, a construction is illustrated for use in connection with such bars 12 as are adapted to connect with a notch 31. In these cases, bars 112, preferably made with a flat end portion 45, are provided with a through opening 46 having extending upwardly therefrom the slot 47. Instead of the extending horizontal portion 13a of bracket 13, there is provided, in this modi ication, the pins 129, made integral with, or in any other suitable manner, secured to bracket 113, said pins having heads 1291. Opening 46 of bar 112 is adapted to be moved over head 129a and then bar 112 allowed to fall so that slot 47 moves over pin 129. Downward movement as caused, for instance, by the use of a crow-bar, on the upper ends of bars 112, is thereby eifectually prevented.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
