SAFE 0R VAULT.

ful-` Improvements in Safes or Vaults, of y which the followingis a specification.'

Burglarious'gattacks v'on safes or vaults have been heretofore attempted by the use of high explosives, for instance, nitro-glycerin, andburglarious attacks have also been more recently attempted by the use of heat action produced by the electric are, and laterally bythe oxygen-acetylene flame, or gas flame of similar nature,`which produces a high degree -of heat, locally applied, and most'recently bysthe employmentof the new lagency named thermit, which produces an intense heat and exceedingly rapid penetration of metal without'noise and has proven to be a most dangerous method of attack upon safes or vaults.^

It is the object of my invention to provide an improved construction for safes or vaults which guards against all of the methodsof attack mentionedor methodsof a similar nature.

My invention isapplicable primarily to built-up burglar-proof constructions in safes or vaults, and I have shown-the same as applied to a vault structure.

The invention will beffurtfher readily understood from the following description and claims, and from the drawings, in which latter:

Figure l represents' a front elevation of a safe or vault door 4with the jamb adjacent thereto, partly broken away. Fig. 2 is .a'

horizontal cross-section of the same on` the lineV 2 2 of Fig. l. Fig. 3 is a vertical cross-section ofthe same on the line y-g/ of Fig. 1. Fig. 4 is a vertical section taken on a line corresponding to the line :z2-m of Fig. 2. Fig. 5 is a cross-sectional detail of one of the inside chrome-steel plates, and Fig. 6 is an enlarged Vsectional detail on the line yf1/ of Fig. l, showing rthe parts adjacent to the joint between the door and jamb.

The construction shown is a preferred form, butit is obvious that my invention may be employed in other forms, a different number of inside layers of metal plates and insulation may be employed, and while I Specication of Letters Patent.

door inthe form shown Patented Aug. 13, 1912.

" have shown'the invention in connection with a door of polygonal vertical cross-section, known in the trade as a square door,it is obvious that t-he 'same may also be applied'to socalled round doors, or doors of other shape, and the invention may be applied to suitable parts of the safe or'vault structure.

1 represents the door and Q'the j amb. The comprises an outer plate .3 and-an/` inner plate 4, of metal, preferably of tenacious, as contradistinguished from brittle properties, for instance open hearth or Bessemer steel. The outer plate is preferably backed by a second plate 5 of metal, preferably of drill-resisting properties, for instance, so called chrome-steel, at

the rear of which a further metal plate 6 is located,the same being preferably of tenacious metal, as open hearth or Bessemer steel.v At the forward face ofthe inner metal plate there'is preferably a drill-resisting metal plate 7, preferably of chromesteel. rIhe arrangement of these plates is selective. The outer and inner plates are preferably of a size to encompass the width and height ofthe, door. in one piece. Alternate Ametal plate and insulation layers are located between the plates described as located at the front and rear of the structure. As shown, one or more series of inside metal "plates 8 are 'located between the forward` andrear plates mentioned, 'each of the series comprising a plurality of plates whose adjacent edges 9 are spaced apart for forming the s ace I0, preferably filled by an insulating lling 11. The respective series of inside plates, if more than one series, is employed, have their adjacent faces spaced apart, as shown bythe space 12, the series of inside ',metal'plates being spaced lfrom the outer and inner :plates by the spaces 1314. These last-named spaces are preferably filled with an insulating material, as shownA by the insulation layers l5, 16 and 17. The insulating material employed is preferably a non-conductor of electricity-and heat. It mayY be in the form of a hard-setting cement. Any suitable insulating material, preferably insulating against the electric current and heat or burning, may be employed.

The series of inside metal plates are preferably of drill-resisting material, for instance, so-called chrome-steeh The chromea. hart-,l but brittle "substance,

i I `l lu steel mentioned in practice usually comof roy invention.

Surrounding the -edge of the' door, there is preferably an edgeifrainin'g 20, which may be a steel frame, located between the vouter and inner metal plates of the door.'

'This framing preferablyv surrounds the edges of theA inside layers of drill-resisting. instal and insulation,the series of metah plates being insulated frointhe framing by tion of' electricity and heat from theouter' 25l portions of the door.v Esch of the pleteso an insulatingniateriall.

tool-resisting plates preventing-penetrationy by drilling or similar action.' Even if the insulation were reached by one of the methods of .penetration und it were forcibly lo- 13' cally -removed', little further damage could be done, for the opening provided by such penetration would be inpractice small in diameter, and, if accomplished for instance4 side of the layer of insulationywhere the provided can be molten metal would pocket and immediately solidify. To continue the action, the molten metal must immediately run out of the way to permit the thermit to attack new metal. In practice only a small quantity of thermit in comparison to the size of opening employed at an ap lisation,

and while it acts quickly to melt t e metal,

it also isses its melting properties almost instantly' nd permits the metal to again solidify, and the attempt to dam up the thermit forholdinglit against the metal beyond the insulation as proven ineffectual.

:30 may of a vault/and 5l is the body thereof this body', being of suitable material and s own broken away. The adjacent edges of the door and jainb are preferably provided with stepped jambsurfaces, shown by the steps 52 onthe jamb and the ste s 53 on the door, aV portion of these ste being on the framings and a portion tisireof ormedby the overlapping of the plates. 1 In practice, the door preferably has a metal to metal fit with the jamb for preventing the introduction of an explosive vbetween the door und jamb. A usual method employed`I in burglarious attacks v:tor .introducing ahigh explosive such as nitro-glycerin between the door and th'e jamb, is to initiate an opening or cracl'between the same by forcingia very thin wedge between the door and the door-jamb- In order to prevent the introduction of a Wedge un* tool to a Sulli- -cient extent to have a wedging action, and to guard against the formation of an opening' or crack between the door and jamb, or a, springing of the metal thereof, in employing my invention, I have provided a shallow meeting joint and a lateral locking joint between the door and jamb for preventing lateral separation between the same.

l Thus in the, preferred form shown, I have provided the door-jamb with an outer rabbet 54, which surrounds the jamb at the outer edge oi' its jamb-surfuce, and preferably located in the outer plate 31, and the outer plate of the door is preferably pro vided with a peripheral shoulder 55, shown formed by an edge rabbet 56V which surrounds the door. The shoulder is received in the rabbet of the jamb, the front face 57 of the door being shown as extending forwardly of the front face 5S of the jamb and having its outer peripheral portion rounded as shown at 59. The outer 'rabbet 54 is shalrepresent the ordinary vestibule l low, and an attempt to introduce avvedgev .and the j'amb, at the jamb-surfaces, I provide the lame with mating laterally Y interlocking j oints.

The ton e and 'groove of the jamb are prefere ly formed in the jamb framing 33, and .the tongue and groove of the door are preferably formed in .the door, these ton es and grooves and the rabbets mentione being preferabl machined to :inaccurate metal to metal gli, tongues andgrooves preferabl adjacent the outer edges of the door and jamb, adjacent to the rabbet and shoulder mentioned, when the door is seated in the jamb, for insuring against the lateral opening of the joint between the door and jamb, and against springing of the metal, by which a crack between the same could be obtained. l 64 is an air-obstructing member or packlng betweeu'the walls ofl the groove and tongue and extending longitudinally thereof about the joint between the'door find iamb when the door is closed. It is shown re ceived in a channel 65 in the wall of the groove, the tongue being provided witlin projection 66, shown as u. knife-edge rib, which extends longitudinally thereof, and is adapted to enter the body of the air-obedgeraming 20 of they introduction thereof *be pre-fA A'ns These joints are' shown-as,

.with the structing packing when the door is closed for compressing said member, which is preferably a soft and slightly resilient body.

The rabbet and shoulder received thereby and the tongue and groove preferably surround the jamb surfacesbetween the door and jamb. Any attempttomelt `or burn through t-he door b at the jntnb surfaces would serve to 'sec :rely unite the door und jnmb by the welding or fusing ofthe metal thereof. The inside metal plates B6, 37 and 38 may be arranged in series of individual plates whose adjacent edges are separated by insulation fillingsv 69 in stag-` gered relation. Y
