Application filed February 5, 1924. Serial No. 690,723.

To all whom z't may concern."

Be it known that we, GUs'rAvE M. Gonn- SMITHitIld CARL BARTELS, citizens of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Safe Construction, of which the following is a specification. I

This invention relates to safe construction, and more particularly relates to burglarproof safe doors and vestibules made up of a plurality of plates or sectionssecured together, one or more of the plates or sections having special characteristics, such as being highly resistant to drills, or to torches, or the like; and the principalobject of our invention is to provide a construction for safe doors and vestibules in which these plates and sections are secured and held together in such away that the structure is thoroughly proof against penetration and entry by means of a torch or drill, or the like, and in which the plates or sections are held against bodily removal under attack. Another object of our invention is to eliminate the neces, sity of relying upon screws to holdthe sections or plates together. A further object of our invention is to provide a safe door and vestibule construction in which material having special characteristics, such as. being highly resistant to drills, torches, or the,

like, is so incorporated that it is substantially co-extensive with the door or vestibule, in the plane thereof, and cannot be removed therefrom or displaced. 1 Other objects of our invention will be in part obviousand in part pointed out hereinafter.

In order that a clearer understanding of our invention may be had attention is hereby directed to the accompanying drawings, forming a part of this application, and illustrating certain possible embodiments of our invention. 7 i

Referring to the drawings, Fig. 1 is a diae grammatical front view of a safe door and its vestibule; Fig. 2 is a perspective View of a section of thedoor; Fig. 3 is a sectional view of a door incorporating a modified form of construction; F ig. 4 is a sectional view of a door incorporating another modified form of construction; and Figs. 5, 6, 7, 8,9, 10 and 11 are each sectional views of one wall of a vestibule, and each shows a different modified construction embodying our invention. Similar reference characters referto similar parts throughout the several views of the drawings. Referring to the the door being supported'by the usual crane hinge 3. As shown in "F ig. 2, a metalsechaving special characteristics, such as torchs [resistance or drill-resistance, is attached to an innerimetallic section 8, with which the drawings, there is shown" I in Fig. l a safe-door l and its vestibule 2,

tion 4, constituting the body of'the door and inside line ofboltfframes 9 may or may not be cast solid. The plates or sections 7 and d are rigidly locked together by means'of interlocking. dovetailed tongue and groove connection 10. A similar connection may bc had between sections 7 and 4. In assembling the construction striprlike sections 11 of .the speclal material are placed within the undercut grooves 6. Then the sections 7 and 8 are fitted into the central cavity in the door I body. section. and the parts are secured and locked firmly together by means of pins 12 which penetrate-the jamb portions of sec tion 4 and enter the section or plate 8. These.

pinscan be a drive fit or a wedge fit. and,

if desired, may be constructed of metal sim ilar to that employed for the section7 and 11. The number and diameter. ofthe pins 12 maybe varied as circumstances dictate and in accordance with the strength required.

The bolts 13 which penetrate the bolt frames 5 and 9 may also serve to holdthe sections 7 and 8 against movement with respect to th body section 4; Preferably the section 7 has a beveled fit, as at 14:, against the side I strips 11, to prevent the section 7 from being moved outwardly bodily in case of a corresponding portion of the front door be coming removed in consequence of ,an attack upon the structure; The outer sides of strips 11 maybe beveled as shown to make their removalmore difficult. I

If desired, the ,jambedge portions of the section 4 may be machined out to provide one ormore grooves, such as 15 and 16, in which additional continuous pieces, such as 17 and 18, of metal having the desired special characteristics may be fitted. These sections 17 and 18 are preferably continuous around the edges of the door and one of these sections, such as 17, may be so located that the location'of the pins 12 are covered and concealed thereby, and access to all the pins cannot be had unless the entire section 17 be removed. Preferably the sections of the material having the special characteristics are of such size and are so located that the sections will be in overlapping relation across the door, and thereby creating a construction which incorporates material having special characteristics extending coextensively across the area of the door in the plane thereof, extending from one edge of the door to the other and from the top to the bottom. Preferably the body 4: of the door is so machined for the strips 17 and 18 that the grooves therefor are slightly underout and thus provides overlapping edges such as 19 and 19 which tend to hold the strips 17 and 18 against displacement and removal from the grooves.

The modified form of construction shown in Fig. 3 is similar to that shown and de scribed in connection with Fig. 2 except that the central cavity in the body section 20 is not undercut and is not provided with outside grooves or recesses for outside strips of metal having special characteristics. A section or plate 21 of metal having special characteristics, such as being resistant to drill or torch, is joined by means of a dovetailed tongue and groove connection 22 to a section 23 and these joined sections are fitted in the cavity of the section 20. Pins 2 1 extending through the jamb portions of the section 20 and into the sections 23 hold the sections 21 and 23 in the cavity. The outside ends of these pins 2 1 are preferably so finished that their location cannot be determined on the edges of the door.

The construction illustrated in Fig. 1 is similar to that illustrated in Fig. 3 except that the cavity in the body section 25 is undercut in a manner similar to that shown in Fig. 2 and is provided with a continuous outside groove 26 similar to the groove 16 shown in Fig. 2. This construction includes pieces. 27 of material having special characteristics located in the undercut grooves, a central section 28 of material having special characteristics, and a continuous strip of similar material 29 located in the groove 26 provided therefor. Pins 30 extend through the jamb portions of the casting 25 and into the metal section 31, to which. section 28 is joined by dovetailed tongue and groove connection, as at 10, which holds the construction rigidly and firmly assembled.

Material having similar special characteristics may be incorporated satisfactorily in the vestibule wal' 2 of the safe in many ways to prevent penetration of the walls by means of drills or torches, or the like. For instance, as shown in Fig. 5, the wall 32 may have one or more grooves, such as 33 and 341, machined therein and strips of material having the desired special characteristics may be fitted into these grooves asat 35, 36, and 37. As shown in Fig. 6, by extending a portion of the vestibule wall 32 outwa *dly, as at 38, one of the recesses, such as 39, may be extended in the same direction to receive larger strips 10 of material hav ing the special characteristics. Instead of extending the recesses for the strips of special material from the jamb, a cavity for strips of this material may be extended from the inner side of the vestibule wall, as at l1. This cavity is preferably tapered forwardly and the strip 42 of material having the special characteristics is similarly tapered so that when it is fitted in the forward end of the cavity it may not be removed forwardly therefrom in case the end of the wall is destroyed in an attack upon the structure. The interior walls of the safe, such as 43, may extend into this cavity and abut the strip 42 from behind to prevent rearward movement thereof. Suitable filling 15, such as concrete or the like, may be employed to fill the space between the front wall 46 of the safe and the strip 42. As shown in Fig. 8, the outer side of the tapered cavity 47 may be the. continuation of the safe side plate as, which extends the length of this cavity. A strip of drill proof or torch resistant material 49 may be located in the forward end of the cavity 17 and may be attached to a metallic section 50 which is arranged to fill the rear portion of the cavity. As shown in 9,'the tapered cavity 51 may have fitted therein a section 52 of material having special characteristics which is attached to another section 53, and

these sections may be held in the cavity by means of pins 54: which extend through the vestibule wall and into the section 53. As shown in 10, the edge of the vestibule wall may be machinedoutalong the line of the pins 54 to form grooves in which material having special characteristics, such as 55, may be located to conceal the location of the pins as and to prevent their removal. If desired, a groove 56'filled by a strip 57 of material having special characteristics may be formed in the vestibule wall so as to extend into the wall from, the side opposite the jamb. In Fig. 11 there is illustrated a construction in which the vestiluile wall 58 has a tapered cavity 59 which is straight on one side, The side wall 60 of the safe extends along this straight side for the full length of the cavity and the remainder of the cavity is completely filled by a suitably tapered piece or section 61 of material having the desired special characteristics.

As many changes could be made in the above construction and many different embodiments of our 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 be interpreted as illustrative and not in a limiting sense.
