PROCESS OF MANUFACTURING FIRE-PROOF SAF'ES.

SPECIFICATION forming part of Letters Patent No; 405,655, dated June 18, 1889.

Appiicaticn fiiai nach 16, 1889.

To all whom, it may concern:

Be it known that I, JACOB BAUM, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio,

have invented a certain new and useful Process of Manufacturing Fire-Proof Safes; and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawro ings, which form a part of this specification. This invention relates to the construction of safes or other similar strong boxes; and my improvement comprises a novel method or process of Ychaiging them with the customary fire-proof filling', which is applied in the following manner: The safe is made of two principal sections-to wit, the outer shell or casing and the inner box, which latter may be integral with the door-frame, or it may be se- 2o curely attached thereto, and said casing is filled about half-full with the plast-ic fire-proof material. The inner box is then forced into this material, thereby compelling the filling' to pack very tightly within the annular space between said box and the outer easing, any Asurplus filling being free to escape at the joints where the door-frame iits into the front of said casing. The two sections are then united by bolting said frame to the casing, or 3o the same result may be accomplished by providing the inner box with flanges, lugs, or other projections that embed themselves in the plastic filling, and thus anchor the inner box so firmly as to prevent its being pulled out after the filling has hardened, as hereinafter more fully described.

In the annexed drawings, Figure l is a vertical section showing the inner box of a safe separated from the outer shell or casing. Fig. .io 2 is a similar section showing said casing charged with the fire-proof filling. Fig. 3 is a section of the safe after the inner box has been inserted within the shell or casing and secured thereto. Fig. et is a similar section of a modified construction of the safe.

` Referring to Fig. 2, A represents the bottom, B B the opposite sides, and C the back, of a safe shell or casing, which members A B B C are here represented as an integral casting, although this construction is not .essen- Serial No. 303,550. (No model.)

tial lo the carrying out of' my process. The shell has an opening D in front to admit the door-frame E, which latter is fitted up close against the flange F of said shell and is secured thereto by screws or rivets G.

H is the inner box, which may be integral with the door-frame, if' desired.

I represents the charge of plastic fire-proof vfilling, composed of any suitable .material or materials.

In carrying out my process the shell is rst turned over, so as to rest upon its back plate C, which act brings the opening D in such a position as to facilitate the proper charging of said shell. The. plastic filling I is then 6 5 poured in until. said shell is about half-full, or at least until there is slightly more filling' within the shell than is absolutely necessary to charge the annular space of the safe. B0X H is then inserted within the opening D and 7o is forced down into the plastic filling, thereby gradually displacing the latter and causing it to ascend around the sides of said box. Consequently by the time the box is completely inserted it is surrounded by the plastic lilling, which is packed in very tightly and fills every corner and crevice of the safe, the surplus material being forced out at the joints between the door-frame and its seat within the shell. The screws G are then run home 8o and the filling allowed to harden, which act finishes the production of the safe, at least as far as the fire-proofing of the structure is concerned. (See Fig.

It will be noticed that this process enables the ready and complete filling of a safe whose outer shell is a single casting, and it is apparent that the lilling is inserted lwithout perforating said shell or otherwise weakening it;

but the process is equally advantageous when 9o the shell is composed of a number of members, as seen in Fig. 4, in which illustration the casing or jacket J .is secured to a front frame K and rear frame L, which latter is integral with the back plate M, said front frame being provided with a flange N, for the doorframe O to .rest against. v

P is the inner box, which is here shown as being attached to the frame O, the rear end of said box being secured to a back plate R. roo

Plate R has flanges or lugs S, projecting some distance beyond the sides of the box P, so as to embed themselves within the plastic iilling, in order that the box may be securely anchored in place when the filling liardens. Therefore these anchoring devices S render it unnecessary to use the screws Gor other visible fastenings.

From the above description it is evident that my process is not limited to any special construction of safe, but can be used whenever the inner box is capable of being inserted within a mass of plastic lire-proof filling.

I claim as my invention` 1. The within-described process of man ufacturing safes, which process consists in charging the outer shell wit-h a plasticiire-proof filling, and then forcing the inner box down into the latter, whereby said filling is gradually displaced and caused to ascend around the sides of said box, so as to enter every corner and crevice of the safe, the surplus material escaping` at the joint between the doorfraine and its seat within the shell, and said box being secured in place, substantially as herein described. v

2. The within-described process of manufacturing safes, which process consists in chargingthe outer shell withaplastic fire-proof lling, and then forcing the inner box down into the latter, whereby said filling is gradually displaced and caused to ascend around the sides of said box, so as to enter every corner and crevice of the safe, the surplus material escaping at the joint between the doorframe and its seat wit-hin the shell, and said box being secured in place by anchoring it in said iilling, substantially as herein described.

In testimony whereof I aliix my signature in presence of two witnesses.

JACOB BAUM.
