IMPROVEMENT IN SAFES AND VAULTS.

Specification forming part of Letters Patent N o. 146,04*?, dated December 30, 1873 application filed April. e, 1873.

ASE B To all whom t may concern: as described in my application for a patent Be it known that I, JOHN ORUMP, of Phila bearing even date herewith. On the inside of delphia, in the county of Philadelphia and the b0dyplates, over the hard-metal iilling B, State of Pennsylvania, have invented certain there is placed a plate of hardened steel or Improvements in Safes and Vaults, of which wrought-iron, D, to give additional strength the following is a specication: and security. This inside lining, and also the My invention consists in constructing a safe outside covering C, is secured in place by or vault body or door of an outside plate, havscrews passing through into the cast-iron. Ining its inner face provided with transverse side of the lining D there is a layer or coverribs, and an inside drill-proof backing, secured ing, E, of asbestus, alum, and plaster, or other in place solelyT by the said ribs; in concealing like materials which are non conductors of and protecting the joints of the body-plates by heat; and inside of the non-conducting matean outside wrought-iron sheathing' and in rial there is another iron or steel plate, F,to combining with the body a lining' of metal hold said material in place, this plate being plates and noneonducting material, as hereinheld by screws or bolts, d, passing through after more fully explained. into the cast-iron ribs or flanges of the body- Figures l, 2, 3, 4, and 5 are sectional views, plates. showing different forms or modifications of my In Fig. 2 the construction and arrangement device. of parts are the same as in Fig. 1, except that In Fig. l, A A represent cast-iron plates, a the ribs or ilanges are of a ditferent form, beseries of which are usually bolted together ing all inclined to one side, and widened at the through inside flanges on their edges to forni outer edge, instead of being made in the zigthe body of the safe or vault. The plates are zag form shown in Fig. l. In this case a drill provided on the inside with. ribs or iianges a, can be passed obliquely through the body by which run parallel with each other across the following the ribs 5 but, owing' to the great plates, and which, in their cross-section, are of thickness of metal, this will be practically ima zigzag form. The spaces or cells between possible, but even should thc drill find its way the ribs are filled up flush with franklinite, through the rib, it will be stopped by the inchilled iron, or other drill-proot'-material, B, side plate or plates. which may be poured or cast therein in a In Fig. 3 the construction is essentially the molten state, or inserted otherwise. Owing same as in the two previous forms, the ribs to the bent or crooked section of the ribs, it willbe seen that the hard metals in the adjoining' spaces overlap each other, so that a drill cannot be passed through from the outside of the body in any direction without coming in contact with and being stopped by the hard drill-proof substances, or passing obliquely through the entire thickness ofthe ribs, which is practically impossible. The whole outer surface of the cast-iron body-plates is covered with a plating of wrought-iron, O, which serves to conceal the joints between the cast-iron plates or sections, so as to prevent burglars from commencing operations at the joint, where they may think they can work to more advantage th'an elsewhere. rlhe -joints will also be protected by steel bars g, and other safeguards,

being curved in cross-section and widened at thc outer edge.

Fig. 4 shows still another arrangement, the castiron body-plates being provided with dovetail or rounded grooves, and the franklinite or chilled iron arranged to fill the grooves, and also form a plating or coating' over the entire inside surface of the plates. The inside plate D is also used in this case to prevent the hard metal from being fractured by blows. The non-conducting material may or may not be used, as preferred.

Fig. 5 illustrates another form of wall, consisting of two outside plates, the inner one of which has Z-shaped ribs riveted to its inner face, the spaces between the ribs iilled, and their inner faces covered with franklinite or chilled iron, and the inside face of the latter covered with a plate of iron or steel, held by bolts or rivets passing through into the ribs. The rivets are inserted, and, if desired, the plate secured in place, before the hard metal is introduced. Inside of the whole there is a layer of non-conducting material, E, held in place by a covering-plate, F, as in the other arrangements hereinbefore described. The Z form of the ribs, and their being covered or inclosed in the hard metal, precludes the possibility of getting a drill through without penetrating said material. In Figs. l, 4, and 5, the hard material is so disposed that a drill cannot possiblyT pass through without coming in contact therewith, while in the others a drill can be passed through clear of the hard metal, but only by passing through a great thickness of cast-iron obliquely. The hard metal may be arranged, however, in all cases, so as to obstruct the drill in whatever way it may be inserted.

Although, as before stated, the drill-proof material may be inserted while in a solid form, by sliding it endwise into the spaces, still it is considered prefer( ble to pour it in in a molten condition and allow it to harden in place. In order to admit of the hard material being shoved into its place, it` will be necessary to cut away a portion of the iiange at one side or end of the body-plates, and this it is not desirable to do.

e It is 'obvious that the ribs, and consequently the channels between them to hold the hard metal, may be made in any form desired to accomplish the desired end of having the hard metal obstruct the entrance of a drill. The hard metal may be extended outward to form a covering or plating over the edges of the ribs when they are shaped asin Figs. l, 2, and 3, as well as when made in the other forms.

When it is considered desirable, and the form of the recesses will permit, plates of chilled iron or steel, or other like material, may be placed in the parallel grooves or spaces before the drill-proof filling is introduced.

It is obvious that my improvements may be applied to safes and vaults of all sizes and forms, and to those having their walls made in a single piece, as well as to those made in parts or sections, and also that, if desired, the ribs or flanges may be arranged to intersect each other.

The ribs, when parallel, maybevertical, horizontal, or inclined, and, if desired, they may be made of a curved or irregular form. The only requisite is, that the drill-proof material shall be so arranged as to at least prevent a drill from passing through the thin portion of the body-plates and into the interior of the safe, although it is, of course, desirable to prevent also a drill from passing through the ribs.

Having thus described my invention, what I clann is- 1. A vault or safe body or door consisting of an outside plate, having its inner face provided with transverse ribs of an irregular cross-section, and of a backing or filling of franklinite, chilled iron, or like'material, applied and held by the ribs, substantially as shown and described.

2. The cast-iron body-plates A, having the ribs formed solidly on their inner faces, in combination with the backing of franklinite, chilled iron, or like material,.held in place solely by the ribs, the latter being made of such form in cross-section as to interlock with said material.

3. In combination with the east-iron plates or sections A, provided with the drill-proof backing, and united at their edges, as set forth, the wrought-iron facing C, screwed or riveted to the east-iron, for the purpose of concealing and protecting the joints therein.

4. The safe or vault-body consisting of the plates A, having the ribs a, filling or backing B, of franklinite or like material, hard-metal plate D, non-conducting material E, and inside plate F, all united and arranged as shown and set forth.
