B. T. GIALDINI SAFE Filed DGC- 14. 1925 4 Sheets-Sheet 4 UNITED STATES PATENT OFFICE BRUNO T. GIALDINI, OF CANTON, OHIO, ASSIGNOR TO THE DIEBOLD SAFE & LOCK COM- PANY, OF CANTON, OHIO, A CORPORATION OF OHIO SAFE Application filed December 14, 1925. Serial No. 75,162.

The invention relates to safes for the protection of valuables, documents, records and the like against the usual hazards, and particularly against the hazards of fire, of explosion, and of combined fire and explosion.

Safes for this purpose should be built to withstand and endure with a substantial margin of safety, separately or simultaneously, the hazards of impact, crushing loads, and falls, and long periods of intense heat.

The objects of the present improvement are to provide a safe which shall meet these requirements, maintaining a relatively low inside temperature under fire exposure, and which shall have great strength, light weight, monolithic reinforced heat resisting insulation having in itself inherent structural strength, and having interlocking parts providing for expansion of the same while subject to heat without destroying their structural relationship with each other.

These and ancillary objects are attained by the use of an inside main structural frame surrounding and maintaining a compartment in which are placed the valuables, documents, records and the like to be protected, the main structural frame and compartment being themselves surrounded by a combined heat and compression resisting monolithic shell having tension reinforcement preferably secured to the structural frame, and the compartment, main frame and monolithic shell, all being surrounded by a welded and slidably interlocked external case; a suitable door, castors, lock and other usual fittings being provided for the improved safe structure thus set forth in general terms.

A preferred embodiment of the invention is illustrated in the accompanying drawings forming part hereof, in which- Figure 1 is a vertical cross section of an improved safe as aforesaid, taken as on line 1 1, Fig. 2;

Fig. 2, a horizontal cross section of the same, taken as on line 2--2, Fig. 1;

Fig. 3, an oblique perspective view of the main structural frame and tension reinforcing for the monolithic shell as preferably assembled for combining with the other safe parts;

Fig. 4, an isometric view of the improved safe, the top, and upper wall and door portions of the external case, the monolithic shell, and the inner compartment being broken away to illustrate the main structural frame and tension reinforcing secured thereto.

Similar numerals refer to similar parts throughout the drawings.

The improved safe indicated at 1, includes the main structural frame indicated at 2, surrounding and maintaining a five-walled compartment indicated generally at 3, for receiving valuables, documents, records and the like for protection, and a livewalled monolithic heat and compression resisting shell 4, the shell being provided with tension reinforcing means indicated generally at 5, and the frame compartment and shell being all surrounded by an improved, external fivewalled interlocking case, indicated generally at 6, having a suitable door 7 mounted upon one of its corners as by hinges 8, the entire structure thus formed being preferably mounted upon castors 9 for easy rolling movement when desired.

A preferred method of constructing the safe consists of first assembling the main structural frame 2 by making a front mitered angle frame 10, a rear mitered angle frame 11 and connecting the front and rear angle frames by angle struts 12;

The front mitered angle frame 10 may preferably include angle members 10a, 10b, 10c and 10d, having angularly cut ends for mitering with each other and being joined to each other at the miter as by welding, indicated at 13.

Likewise the rear miter frame 11 may preferably include angle members 11a, 11b, 110 and 11d, having angularly cut ends for mitering with each other and being joined to each other at the miters as by welding, indicated at 14. 4

The angle members 10a, 10?), 100, and 10d, include rearwardly extending legs 10a', 10h', 10c and 10dv and outwardly extending legs 10a, 10b, 100 and 106V; while the angles 11a, 11b, 110 and 11d include forwardly extending legs 11a', 11b', 110 and 11d and inwardly extending legs 11a, 116, 110 and 11d g and the front and rear angle frames are preferably connected to each other by the angle struts 12, including legs 12 and 12 by arranging the struts to form corner struts having outer corners 12 so that the forward ends of the struts lmay be connected with the rearwardly extending angle legs 10a', 106', 10c and 10d at their corner abutments 15 as by welding, and the rear ends of the struts likewise connected at the corner abutments 15 of the forwardly extending angle legs 11a', 116, 110 and 11d.

The main structural frame 2 thus includes a plurality of angle corner members 10a, 116,

12, etc., determining the edges of a geometrilcal solid and the angle corner members extending towards each other at intersections adjacent their ends, and the members are connected with each other at each intersection.

By this construction and the use of proper sizes of angle members, a main structural frame is provided which may be depended upon to carry the loads to which the safe may be subjected and which will be transmitted to the frame through the other safe parts.

For convenience in assembly the tension reinforcement means indicated generally at 5 may then be positioned about the frame 2; and includes a series of spaced reinforcing bars 17 wrapped around the frame angles 100, 110, 11d and 10d and preferably secured as by welding at the ends 160 and 16d to the front frame angles 10c and 10d, and spaced from the rear frame angles 11o and 11d, as by saddles 17 secured thereto as by welding, a series of spaced reinforcing bars 18 wrapped around the struts 12 and the bars 16 and spaced from the struts by saddles 17 and a series of reinforcing bars 19 wrapped around the angles 10a, 106. 11a and 116 and bars 16 and 18, and spaced from angles 11a and 116 by saddles 17 and preferably secured to angles 10a and 106 at the ends 19a and 196 as by welding.

In other words the three series of reinforcing bars 16, 18 and 19 determine three sets of mutually intersecting planes. It is obviously immaterial what order is used in wrapping *the series of bars around their intersecting members, but the arrangement illustrated is adapted for convenient assembly.

The external five-walled interlocking case indicated generally at 6 may then be constructed by the use of improved front external corner angles 20a, 206, 20o and 20d and improved rear external corner angles 21a, 216, 210 and 2106.

A front external miter angle frame may be mad-e from the angle members 20a, 206, 20c and 20d, and a rear external miter angle frame may be made from angles 21a, 216,

l 210 and 21d and the two frames may be miter connected to each other by external corner angles 21e, and the fastening means for connecting the external angle frame members may be welds as at 22 and 23.

The angle pieces 20a, 206, 20c and 20d, include rearwardly extending legs 20a', 206, 20c and 20d and the angle pieces 21a, 216, 210 and 21d include forwardly extending legs 21a', 216, 210 and 21d and inwardly extending legs 21a, 216, 210 and 21d, all of these legs being provided with reversely extending folds 24 for slidable interlocking engagement with oppositely extending edge folds 25 of the case side walls 26a, 266, 260, the case bottom wall 26d and the case top wall 26e, respectively, as illustrated.

In the preferred method of safe assembly external corner angles of the interlocking case ar-e interlocked with the wall plates 26a, 266 and 260 and the bottom plate 26d, and the main structural frame 2 and attached tension reinforcing means 5 are arranged in the the insid-e compartment walls embedding the H main structural frame and the spaced tension reinforcing means to form the {ive-walled monolithic shell 4, after which the remaining parts of the safe may be conveniently assembled including the case top wall 26e and the compartment bottom wall 29d and the frame jab sections 276 and 27 c.

It is apparent that a safe is provided by the above described construction whose main structural frame 2 is protected from heat and other hazards by the monolithic shell 11 and the external interlocking case 6, and the monolithic shell, being provided with tension reinforcing means 5, is in itself an efcient structure of a character similar to reinforced -4 side surfaces of the monolithic shell from deteriorating influences such as the crumbling efiect of flame.

For cutting down the weight of the safe before pouring the monolithic shell, suitable removable devices may be inserted for formhan. 'gru CII atl/urb Dtv-iets.

ing the shallow depressions 30a, 30?), 30o, 30d and 80e.

For further reinforcing the monolithic shell. met-al fabric or lath 3l may be incorporatedas desired.
