In order thata clearer. understanding of this invention may be had, attention is hereby directed to the accompanying drawings, forming a part of this application and illustrating certain possible embodiments'of my invention.
fReferring to the drawings, Fig. 1 is a fragmentary sectional view of a metallic structure embodying my invention; Fig. 2 is: a perspective view ofa fragment of an edge ofthe door of said structure; Fig. 3 is al perspective view of a fragment of the jamb portion 4of such structure; Fig.. 4l is affragmentary sectional view taken on` the line l--l of Fig. 1; Fig. 5 is a fragmentary sectional view of a modified ferm of jamb and rdoor edge wall construction; Fig. 6 is a fragmentary sectional view of another modification of the jamb wall and door edge wall; Fig.' 7 isa fragmentary sectional view taken on.` the line 7 7 of F ig. 6; and Fig. 8 is a fragmentary sectional view of still another modified jamb and door construction. Similar reference characters referto similar-parts throughout the several views of the drawings.
Referring to the drawings, the structure includes a body member having a doorway and jamb, and a door having edge walls adapted to seat in said jamb. The said body portion includes outer walls, such as 1, andy inner walls, such as 2, and jamb walls suchl as 3. Thedoor comprises outer wall 4, inner wall 5, and edge walls, such as 6. Jamb wall 3 and door edge wall G are of conventional -step formation, except that each is provided with two lines of heat-retarding perforations or apertures, also with metallic tongues extending sidewise from the walls into the conventional filling material 7 provided in theI body portion and in the kdoor portion, and are provided with joint-sealing, insulating material, all as will now be particularly described.
As shown, the door edge wall 6 is provided with an outer line of apertures 8 and with an inner line of apertures 9, said lines of apertures being spaced from each other and in effect, divide the jamb wall 3 into three portions: an outer portion 10, a median portion 11, and an inner portion 12. Portions10 and 11 are out of heat conducting contact with each other except for the small metallic portions 13 which are present between adjacent apertures 8, and portions 11 and 12 are out of heat conducting contact with each other except for similar small metallic portions lll which are present between adjacent apertures 9. At the rear of the door a conventional chamber 15 may be provided for bolt work, one of the bolts being diagrammatically represented at 16. The bolts are adapted to slide back and forth through suitable perforations or apertures in the portion 17 of the Idoor edge. The edge of rear wall 5 of thejdoor is flanged toward the front and is there parallel with the inneredge of wall portion 17. A strip of insulating material 18 is firmly secured between said portions of members 5 and 17, and serves to retard or prevent the conduction and .travel of heat from the `portion 17 to the rear door wall 5. Extending sidewise from the inner surface of door edge wall Gare metallic tongues or projections 19 which enter substantially within the filling l 7 of the door and serve to diffuse and radiate heat thereto, ythus retarding the travel of heatV through the door wall 6 or alongv a path behind said wall. These projections or tongues 19 may readily be formed by stamping out the apertures 8 and 9 in such a way that the removed metal is bent sidewise of the wall 6, forming the apertures and projections in the one operation. However, if desired, such radiating tongues may be provided in other ways, as by securing separate angle-shaped.members, such as 19 (Fig. 8), to the jam and door edge walls, as by welding or by other suitable means. Members 19 may be continuous yor interrupted, as desired, and may be employed either without perforations orv lacings in the walls or in combination therewith.
The jamb walls 3 are of a construction similar to the construction of door edge wall (i, in that the jamb walls have an outer line of apertures 20, an inner line of apertures 21, and radiatingtongues or projections 22 extend-ing sidewise from the rear of the-j amb wall into the filling material 7. Therjamb wall is thus divided into three portions: outer portion 28, median portion I2li and inner portion 25, each portion being separated from the adjacent portion by a line of perforations and being out of heat-conducting contact with each other except for the small portions of metal, such as 26 and 27 which remain between adjacent apertures 20 and 21 of each line. At the inner portion of the jamb wall is a bolt-receiving pla-te 28 separated from the portion 25 of the jamb wall by a strip of suitable insulating material 29, whereby said portions 25 and 28 are kept out of heat conducting contact with each other, and whereby the travel of heat is retarded and prevented between such parts of the construction. The inner end of portion 28 is separated from the edge of the rear sidewall 2 by a strip of suitable insulating material 30 which retards and pre-- vents the travel of heat from the portion 28 to the inner wall 2 of the structure. The end of member 28 which is disposed toward the front of the structure is angle-shaped so as te provide a shoulder or fiange 31 behind fil which thebolts 16 are adapted to lock. Flange or shoulder 31 is reenforced by the abutment thereagainstl` of insulation strip 29, jamb wall 3 and iilling material 7. This .construction eliminatesthe necessity of providing the usual perforations for the bolts in the portion 28 of the jamb and permits a larger amount of filling material to be incorporated in the structure at this location than is usually possible. On the inner end of bolt-receiving jamb portion 28 is a flange 32 which fits against the insulating strip 29 and which ends in an upset iiange 33 projecting toward the front of the structure. The end of iange 33 is adapted to be positively contacted by the insulating strip 18 provided on the inner face of the door and cooperates with such strip to form a seal which prevents the entry of heated air from thejoint between the jamb and door walls into the interior of the structure when the door is closed.
4 The lines of apertures on the jamb and door edge walls may be so arranged that when the door is closed they will be in registration or not, as desired. Also, insulatingr material may be provided atany suitable point or points along either the jamb walls or the door edge walls. Such insulation may conveniently take the form of strips of insulating material, such as rubber, asbestos, or the like, laced in and out through one or more of the lines of apertures on either or both the jamb wall and the door edge wall. Such a lineof lacing maybe so arranged on one of the Walls as to closely contact the wall of the other member when the door is closed, or a line of lacing may be provided in each of two registeringr lines of apertures, one on the door and one on the jamb, so that when the door is closed, they will be brought tightly together, and will co-opcrate to form a seal which closes the joint between the jamb and the door walls and which retards or prevents travel of heat through the joints. As shown in the drawings, a line of lacings 34, of asbestos or some other material, may be associated with the line of apertures 8 on the door, and a coacting lacing 35 of similar material may be associated with the line of apertures 2l) on the jamb wall. iVlien the door is closed these two lines of insulation are adapted to press tightly together, sealing the joint 36 between the walls 3 and 6, and cti-operating with the seal provided by flange 33 and insulation 18 to provide an intermediate, insulating dead air chamber 37.
.in one possible modification of the construction above described, instead of making the jamb and door walls of the conventional ste-p formation, they may be of serpentine or tortuous construction, shown in Figs. 5 and 6, in order t0 present a longer stretch of jamb and doorwalls which must be traversed by heat before such heat reaches the interior of the structure. Such tortuous jamb and door wall construction may advantageously be combined with one or more lines of aperturesor perforations in said walls and with lacing of insulating material woven through such lines of perforations.
As shown in Fig. 5, the inner safe wall 2 is shown to extend tothe outer surface of the structure, first forwardly along a straight jamb portion 50, then rearwardly at an angle to portion 50, as at 51, creating a forwardly disposed projecting portion 52, then forwardly at an angle to portion, 51, as at 53, and then forwardly, as at 54, tothe front of the safe. The door edge wall is formed to complementary shape, having a forwardly extending portion 55, then a rearwardly eX- tending portion 56 creating a recess 57 adapted to receive projection 52 of the j amb wall, and having a portion 58 which is complementary to jamb portionv 53, and a portion 59 which is complementary to amb portion 54A. By this zig-Zag or serpentine construction of the jamb and door walls the length of the walls through which heat must travel to reach the interior ofthe cabinet from the `outside is` increasedk materially over the conventional stepped construction. In addition to this I preferably provide the jamb and door walls with one or `more series or lines of apertures, such as 60 and 61; also with Aone or more series or lines of sidewise extending radiating iianges 62 and 63, which extend into the iilling material 7; and also with lacing of insulating material, one, such as 64, on the jamb, and` one, such as 65, on the door wall, adapted to register with each other and to coact to seal the joint 36 between the jamb and door walls. These apertures, radiating anges, and lacings may be similar in structure, in cooperation, and in function to the apertures, radiating ianges, and lacings referred to heretofore. By reason of the specific configuration ofthe jamb and door edge walls expansion of said walls, under the influence of heat, will cause a tighter sealing of the joint. A sealing of the joint may also be effected by permitting jamb wall projection 52 to come into close contact with `the jamb of the recess 57 of the door wall. A seal at this location in combination with a seal effected by the lacings 64 and 65 will produce an insulating dead air chamber 66 between such seals, and thus further enhance the resistance of the structure to penetration by heat. j
The construction shown in Figs. 6 and 7 is somewhat similar to the construction shown in Fig. 5, in that both` the jamb wall 67 and the door edge wall 68 are of tortuous or serpentine construction and jamb wall 67 having a projecting portion 69 fitting into a. recess 70 on the door edge wall 68. As shown, however, the jamb wall is provided with an outwardly opening. dovetailed recess 71 in which is located and secured a strip 72 -of insulating material, such as rubber, asbestos, or the like. The door edge wall is provided with a complementary, opposite dovetailed recess 73, opening inwardly, and which contains a strip 74; of similar insulating material. The construction is such that when the door is closed the exposed portions of the insulating strips 72 and 7 4- are pressed tightly together, thus forming a tight sealing of the joint 36 between the jamb and door edge walls. yThe insulating strips 72 and 74 are preferably of resilient material in order that the sealing of the joint may be insured at all times, and to eliminate the danger of the strips heilig warped or compressed out of shape permanently by continued operation of the door. In combination with such construction, if desired, I may provide one or more series of lines of apertures, radiating flanges, and lacings of insulating material, such as have been described above. In this embodiment I find it advantageous to provide a series of apertures 75 along the bottom walls of each of the recesses 71 and 73, and to provide radiating flanges 76 adjacent each of these lines of apertures and extended into the filling material 7 contained in the structure. The apertures 75 and radiating flanges 7 6 are similar in construction, cooperation, and function to the apertures and flanges de scribed heretofore.
Preferably each of the insulating strips 18, 29, 30, 72 and 74; also each line of apertures 8, 9, 20, 21, 60, 61 and 75; also each line of lacing 34, 35, 64 and 65; also each line of radiating flanges 19, 22, 62, 63 and 76; as well as jamb tongues 52 and 69, and cooperating door wall recesses 57 and 7() and jamb and door insulation holding recesses 71 and 73, extend continuously about the entire jamb and door, although, obviously, any one or more of these various elements of the construction may be omitted, or be made i'ioircontinuous, or otherwise be modified without departing from the scope of this invention.
In my application Serial No. 651,467, filed oneven date herewith, I have disclosed jamb and door walls comprising a plurality of separate portions and continuous heat radiating flanges extending sidewise from said walls into the lling material. l Reference to such application is hereby made.
From the foregoing it will be readily apparent that the travel of heat through the jamb walls of'the construction illustrated in Fig. 1 is retarded and prevented first, by line 2O of apertures; second, by line 21 of apertures;` third, by insulating strip 29; then by insulating strip 30, and also by reason of the fact that baffle flanges 22 conduct, radiate and diffuse heat travel along this wall into the filling 7, whereby said heat is absorbed. The travel of heat along the door edge walls 6 is retarded first, by line 8 of apertures; second, by line 9 of apertures; then by insulating strips 18, and also by heat radiating flanges 19 which conduct, radiate and. diffuse heat from the wallf into filling material 7, whereby such heat is absorbed. The travel of heat through the joint between the walls 3 and 6 is prevented b v the seal provided by cooperating insulating lacings 34 and 35; by the seal provided by the coaction between the flanges 33 and infxulating strip 1S, and also by the insulating dead air chamber 37 provided between said two seals. rlhe travel of heat along a path or course behind the jamb wall 3 is retarded by radiating flanges 22 which absorb heat traveling through and along such path and which radiate and diffuse such heat into the filling 7, and the travel of heat along' a path or course behind the door edge wall 6 is prevented -by radiating flanges 19, which function similarly to flanges 22, and which conduct and radiate heat into filling material 7 of the door.
As above pointed out, the lines of aperturcs and the radiating flanges of the modifications shown in Figs. 5, 6, and 8 function in a similar manner, and the lacings shown in lfig. 5 and the insulating strips shown in lfig. 6 serve to seal the joint between the jamb and door walls. The tortuous jamb and door wall construction serves to retard the travel of heat directly through these walls, and also servesto radiate the heat into the filling material of the jamb and door, which material absorbs such heat and effects a cooling' of the jamb and door walls.
As many changes could be made in the above. construction and as many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
