To all whom t may concern.'k l

Be it known that I, DAVID a citizen of the-United States, residing in the borough of Manhattan,y city, county, yand State ot `NewjlYorl,` have invented certain new 'and useful Improvements in` Safes, Safe Cabinets, and the like, of whichfk the following is aspeciication.

My invention relates tof safes, satev cab,- inets-.and the like, andjparticularly to the portions of such structures ,which are `at and adjacentthe joint between the jamb ,walls ata doorwayy and a door. v Y f'Ihe principal object of my invention-11s to Vprovide means for retarding travel of heatinto the interior of the structure, and more particularly toprovide means for re,- tarding such travel of heat through the jambV walls;V through the door edge walls; through the joints or cracks between the jamb and door edgev walls.; and also along 'paths or courses behind said' jambland door edge walls V Other objects will bev in part' obvio-us and in part pointed out hereinafter.

In accordance with., my invention, I provide metallic tongues or plates on the jamb and door edge wallsfwhich plates extend `into the interior of the jamb and door and which serve to radiate andditfuse heatto the air or filling material there situated, thus` acting inthe manner of radiators to'de-V crease the temperature of the jamb and 'door edge walls and to retard 'the heat travel through these walls towardfthe interior vof the'safe. These tongues orprojections also are in position to intercept heat' traveling behindthe.wa.lls and 4serve to ditluseand yradiate heat traveling along these, paths.l ,As a yfurther Ameans Vof retarding for Vpreventing heatltravelto the interior of the structure lI provide two-partja'mb and vdoor edge walls, the twovparts beingsubstantially out of heat-conducting contact withv each other, and

in combination'ther'ewith, I prete'rably'proT vide insulating materialen jamb .and dooredge wallsinfsucli` manner that when'the door .is closed an air-tight seal will be present across the jointbetweenf-the door edge and'` jamb walls.

Q In o rderA that; a clearer y.understanding. ot

my invention may be had, attention is hereby directed to the accompanying drawings, forming a part of my application and illustrating certain possible embodiments; of y my invention. VvReferring'.to the (drawings, Fig.

II. BELLisronja,

1' is ya fragmentary.sectionaljview of la metal- Y lic struct-ure, includingk ay portion of the jamhand aportionofa door edge vseated in the jamb;. and`;Fig. 2 yis' aview., similar to 1 showing a `possible moditicationof the c onstructionfot the jamb wall and of the door Afedge wall which is seated therein. Similar `reference characters refer to similar lparts throughoutthe several views of vthe drawings. y .v

Referring to Fig.` A1 of the drawings, the structure illustrated is of a typeJ commonly walls, suchk as l, and innerwalls, suchas'Q,

which at Lthe front of the structure are Y usually eXtended-outwardlyto form the door jamb, andiattheirouter ends are joined to the outer walls, Ysuch asl, by means off angle irons, such as 4; -L With such a construction vemployed ,for safe cabinetsV andthe like.

heat is very apt to travel through the con- Y ducting vjamb portion'V of wall 2 into 'the interior of the cabine-t.r To retard the heat i travelalong this jamb portion, I do not eX'- tend the wall 2 to the f outside ot the structu- I'e but shorten thiswall so that it will stop at a place somewhere intermediate'gthe inner land outer portions of the strucyture.Vl Thus portion 3 forms arr-inner portion `ofthe )amb wall.` lI form an outer por# tion of thejambwallby-- utilizing a separate wall plate 5', the outer end-Hof whichissuit yably secured, as by welding 'on otherwise', to

.the jamb receivingA portion oangle ironia;

Plate 5 is ot such size vthatit does not extend to or` contact with jamb wallportiion 3', thereby providing an insulating kspacexbetween the twov jamb wall portions 3 and V5, .which acts as a heat insulating mediumand retards the travel ot heatv from ythe wall portion 5 to the wall'portion 3i-Wall portion 3 and wall portionl 5 are preferably/provided with parallel ianges 6vr and 17, and a strip of suitable insulatingmaterial 15,-such loiheat, is placed between flanges 6 and?. To secure rigidity, flanges and 7 may be riveted or otherwise secured together, asiby means oit rivetsS; y

The construction of thedoor `is similar to ,as rubber,.asbestos .or other non-conductor the construction. above described,'in that it includesanouter wall 9, and an `inner wall 10 which has aportion 11 extended forwardly toform the inner-,portion ofthe wall edge but not extending to the outer wall 9. AnV

outer-wall edge portion 12 is. secured, as by welding or otherwise, to the outer wall9 and extends inwardly, but does not reach or contact'the wall portion 11.Y These vportions 11 and 12 also have horizontal -fianges and 14 spaced from each other, 'with a strip VVof suitable insulating material 15 disposedl stri-lotion,I except `that a considerableportion IVofthenoneconducting strips y15 are vleft eX- zposed, and are vso positioned that when the `doorifs closed they exposed portions of these st-ripsfwill press one against the 'other' and fe'ffect 'a substantial-sealing ofthe joint between theV jainb walls and the door edge "walls, thus fserving', to prevent land retard heat travel through'such joint.

"'ln orvder'fto prevent and-'retard the travel of Q'heat int-o the interior Vof the ystructure :along paths behind the jarnb walls land the door edge walls, the flange G-of the jamb 'iwallsan'd the v`"fi'ange 13 `of the door walls are'ffeX-tende'd as at 6 and 13' into the spiace between the outer :and inner `walls ofthe construction. TheseA flanges serve toV radi# a'tean'd*diffuse 'heat into the air'or lilling 'material V17, whichever 'is vpresent between fthe walls 1 -and 2 Vof the cabinet Vbody and between `jthe walls V9l and yl0 of the door. rllhesefflanges are :particularly usefulA for ab serbi-ng and "diffusing heat which Vmight v-trave'l' behind lthe'jainb wall 5 Yand the door wall e12th-rough acrack there Vproduced by 'reason o'fjtheshrinlage ofthe filling material 157 away frein these walls due tot-he influence of intense Vheat upon Ythe structure. j

Gbviously, lfianges 7 land v14-'1nayalso be eX- tendefd in'f'the Vabove manner.

t Aun'odifield 'construction is illustrated in Figp'f-whereiln it is Vseen that the V"inner portion 18'of the janob wall has a straight portion 19 Iextending forwardly, then curves backward, -as at 20, fforming a forwardly disposed projection 21,' then curves forwardly, fas-at 122,-for1ning'a forwardly open recess-or 'pocket23, and then has a -ange portion 24extendingjsidewise. The outer portion Q5 -`ofthe Vjanibwall has a straight port-ionextending -inwardly, at the end of which/vis --afU-shaped Vportion 26 iextending Vsid'ewisefand `open toward vand receiving. the .fiange' 24be'tweenits :walls in spaced, nonconta-cting relation thereto.
