BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 261,538, dated July 25, 1882.

w Application tiled Apiil 2, 1 'T!l. Renewed December 220, IFFI. .\lodt:l.)

To all whom it may concern Be it known that 1, WILLIAM ConLtss, ot' the city and county of Providence, in the State of l-thode Island, have invented certain new and useful Improvements in Burglar-Proof Safes; and I do hereby declare that. the following is a full, clear, amt exact description t h root.

l. have in Letters Patent issued tome April 30,1872, described a spherical form of safe with provisionsi'or properly operating the door 'thereot', which possesses marked advantages.

It has long been proposed to toughen and strengthen rcctangularsat'esby bars oi'wrought 1 iron or steel inclosed within the casting. l

have discovered and practically wrought out a modc-ot'fipplyiug' analogous bars in my spherical sai'e, so as torealize tho-ad 'antagos due thereto without interfering with the pecu- 2o liar qualities of the spherical sale, and so as to give increased strength due to a lirmuniting of the bars together before their introduction into the mold. I have also made a complete union between the cast and wrought metals, so that the sale utilizes for that reason the strength of the tibrous metal more fully than in ordinary sales. 7

The accompanying drawings term a part of .this specilication, and represent. what 1 con- 0 sider the best means ot carrying out the invention.

Figure l is a view of the basket, of wrought iron or steel, which I prepare to strengthen the main bodyot' my sale. The interior or hollow side is n-escnted toward ti: i eve. l i 2 i. 1 3 s partial section, showing the basket without the series of internal bars. The stout bar which unites the others by receiving them through it shown in strong lines. The positions merely of the others are shown by dotted circles. Fig. 3 is a partial section at right angles to'l ig. L, and showing the basket with its internal parts fully in place. These parts, except the stout uniting-bar, may be attached 5 by small wires. 1 have indicated no attempt to unite the parts of, the basket strongly except by the single. main hoop or uniting piece. Figs. 4- and-5 show n'iyc orresponding stronglynnited frame for what I term the front ring.

. Fig. .L is a face view, and Fig.5 an edge view.

Fig. 6 shows one of the parts detached. Figs.

7 and 8 show my stronglyainitcd basket (or the door. Fig. 7 is a lace view looking at the hollow side. l ig. S is a central section. Fig. fl is aeentral vertical section'through the parts of the sale complete. This figure also shows the parts in their proper relations to each other for use, but with the door moved inward ready to, be opened by reiolving on an axis. (Not shown.)

Similar letters of reference indicate corresponding parts wherever they occur.

.l adopt; the general construction shown in the modification of my original patent dated March 2."), 1873..

A is the. main body, formed with an internal screw-thread, a.

"Ui's tlie trout ring, formed with a screw thread, 0, and applying strongly to A by turn ing one relatively to the other and keying it against unscrewing by a screw inserted in the joint from the inside.

his the door, which will be understood as equipped with the mechanism shown in the. patent last rel'erred to, or otherwise adapted l'orconveuientoperation and for socurimg when properly closed.

The exteriors of all the parts A, U, and Dare of some hard material which may be cast, and which is adapted to resist driiling-iron castin a chill, i'rankliuite, cast-steel, semi-steel, or the like. This cast metal M is formed in a suitable mold, and ilows around and covers and unites strongly with the interior basket-work.

The baskct-\vork in each instance contains two sets oi pieces, m in, strongly united together. They may boot any wrought-iron or any steel which will endure high temperature;

but I will describe them as soi't and t ugh i'ennsylvania iron. They areproperlycurved casting, and when placed in the moldarc held in their proper central positions in the castiugsbyanchors. (Xotrepresentcih) Thebasket m m is tinned bci'ore it is placed in the mold, and on being surrounded by the melted cast metal the high temperature 01' the cast metal is imparted to thewrought metal and the tin serves'as a ilux, enabling the whole to unite.

In Figs. 1, 2, and 3 there is an additional set of parts, nah-which liejustwithin theparts Lil m and are'lightly attached to the latter by small wires or the like. Such slight fastenings are only intended to serve the temporary purpose of holding the parts in the proper positions until the melted metal M can flow perfectly around them. After that the high temperature will ordinarily destroy the slight wire fastenings (not shown) which hold the parts at and m together; but before this is completed the cast metal M has sulliciently hardened to prevent the parts irom becoming displaced.

' he parts m m are stronglunited of themselves by means which hold them forcibly together independently of or additionally to the holding due to the cast metal M.- The parton is in; the form of astouthoop punched or drilled and receiving theparts m in suchholes. After all are inserted the stouthoop m is compressed tightly upon the parts m by blows of a hammer or otherwise, so that it shall slightly indent the material m and hold the parts strongly engaged.

In Figs. 1, 2, 3, 4, and 5 the same mode of The other end is spread, as indicated, to anchor strongly in the cast metal M additional to the adhesion due to the heated union with flux.

In Figs. 7 and .8 there are stout hoops corresponding to m, and a series of four stout transverse straps with rivets corresponding to an. ,These latter take hold rivetwise of the parts m and hold the whole in a stronglyunitcd basket, :ulditional'to the hold insured by the enveloping cast metal M and the welding or adhesion of the latter to the surfaces.

The basket m m is carefully proportioned ,to the space itis to fill, and is held in such position that its parts will be completely embedded. It contributes to the burglar-proof qualities of the safe by being softer than the surrounding metal, tending by well-known laws to break any drill which may touch it. It also contributes to the strength by holding the arts reliably together after the casting hasbeen fractured by any violence.

The riveting or analogous strong fastening of the parts m m together contributes to'thc strength of the completed structure and aids in holding the bars at the previous stages with the exactnessrequircd for spherical work.

I have experimented on a large scale, tin- As a preparation for the tinning, I first treat the surfaces of the basket with dilute nitric acid and afterward with dilute muriatic acid in which zinc has been immersed. Then the, tinning may be effected by a simple plunging in the bath-of melted tin.

It will be observed that where the main body ring, 0, there are two layers of the wrought iron basket-work--one layer in each part of the safe. I attach much importance to this pecuincreased securityto this part of the structure. In its absence the outer part might possibly be chipped awayor the inner part might be broken across.

The spawling off or crumbling away from the exterior is one of the modes by which a burglar having plenty of time and tools would attack the safe. The basket-work extending over the threaded joint 0 is important in preventing that. y

The rending apart of the front ring in the driven into the latter from the exterior is anconditioned would attempt an entrance. Thebasket-work extending under the scrcw-th read 0 prevents this. r

I claim as my invention- 1.. A wrought-iron basket-work composed of the stout ring m, perforated as shown, in com bination' with the curved ribs or transverse strongly secured therein, adapted to serve in a spherical safe, and to contribute to the strength thereof by their direct connection, as herein specified.

2. The spherical safe described, of wrought and cast metal, the wrought metal being composed of two parts orsets of parts, the part am being perforated and receiving the parts at in the holes thereof, and strongly secured togetherin addition to the junction effected by the cast metal, substantially as herein specified.

3. In aspherical safe,thc independent hoops or rings m of wrought metal, in combination with the basket m m, ofstrongly-joined pieces, and the whole enveloped in a harder cast metal, M, as herein specified.
