SAFE 0R VA'SULT.

SPECIFICATION forming part of Letters Patent N0. 77 5,356, dated November 22, 1904.

Application filed June 4, 1904. Serial No. 211,083. (No model.)

To all, whom itntay concernfl Be it knownthat I, SYDNEY L. SM1TH,a citizen of the United States, residing in Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Safes or Vaults, of which the following is a specification.

This invention relates to burglar-proof safes or vaults, the object being to provide an improved structure of this class in which the door is so formed and secured that it will most effectively resist attempts to open the joint thereof or to force the door from its seat. ln the drawings accompanying and forming a part of this specification, Figure 1 is a part. horizontal sectional view of this improved detail view of another construction of the door-locking lugs,

Similar characters of reference designate corresponding parts in the several figures of the drawings. 7

This safe or vault comprises in the preferred form thereof herein shown and described a body 2 and a circular door 3, each of an integral structure and formed of unmachineable metal-such, for instance, as man- The body has a circular tapered jamb or doorway such jamb being of relatively great depth and partly formed by an inwardly extending integral flange 5, such jamb being preferably square with the contiguous outer surface of the body, an annular step 6 being located in the jamb for engagement with a corresponding step on the door. The door 3 of dome-shaped formation is shown comprising a body 7and an inwardly-extending integral flange 8, the tapered. joint-surface of which carries an annular step 9. cooperating with the step 6 on the jamb. When the door and body are assembled, the outer surface 10 of the door forms a continuation of the outer surface 12 of the body, which sur- Fig. 6 is a detail View of faces in the present instance form apart of a complete circle, so that the door fits into the jamb in such manner that there is nospace or opening at the joint around the door, The inner surface or wall 13. of the door conforms in the structure shown throughout the major part thereof to the inner surface or wall 14 of the body forming part of the front. This,

together with the door-flange, tends to prewhen threads or tapered lugs were used it was not only very difficult as wellas a tedious and expensive operation to grind the threads on .the'door and body to a proper matching fit,

but it was not possible to properly grind the doortoits seat, which is essential in order to secure a metal-to-metal fit of the door and jamb, since if the threads or tapered lugs are integral with the bodyand door they will permit the door to be turned just so far and no farther. At the same time the threads or lugs are also being further ground, which is undesirable, as this will permit play or backlash of the door, resulting in a space or opening at the joint into which nitroglycerin could run. To overcome these difficulties, it has been the usual practice to form these locking threads or lugs on a ring of machineable metal and secure it to the door by bolts embedded V in soft-metal inserts or to attach it in some other undesirable way,-with the result that done with less than two ounces of nitroglycerin used in several small charges and within an hour, all of which would be a burglarious operation. Thepresentimprovement,however, not only enables me to make the tapered lugs integral with the door, so that unless the metal of the door is smashed it cannot be forced out, but enables me to materially reduce the time and expense of grinding the locking parts, since the body-lugs can be formed separate from the body, as there is no strain thereon, and therefore of machineable metal, while also permitting the door to be properly seated by bolted thereto a number of tapered face-plates grinding it to its seat.

The integral lugs 15, carriedby the door, are located in proximity to the inner end of the door-flange in position to overlap the bodyflange 5. For the purpose of wedging the door home tightly to its seat the body-flange has 17, herein referred to as lugs, to permit which soft-metal inserts 18 may be cast into the flange during the casting of the body to re-- ceive such bolts, as the only strain upon these parts is a crushing one, which would not separate them from the body. The inner faces 19:

I case may be, whereupon when the door is in serted and properly rotated such door will be drawn to its seat with a metal-to-metal tight fit at the joint. Heretofore the locking devices carried by the body,.whether formed as threads or lugs, have projected into the door- .way being carried on the jamb-face, in conse-v quence of which the diameter of the door through its locking lugs or threads merely accord with the diameter of the doorway back of the body lugs or threads. stance, however, it will be seen that as the bod ylugs are carried on the innermost faces of the bodyflange-in other words, at one side of the jamb, this being adesirable feature, since the entire front of the safe would have to be pulled out in order to permit the body-lugs to give waythe diameter of the door through itslugs in order to overlap such body-lugs is greater than the diameter of the doorway at the inner part thereof, so that the door-lugs overlap the body-flange where the safe is provided with such flange, or the body itself at the inner end of the jamb, should such flange be omitted, and to enable such door-locking lugs to be formed as an integral part of the door the jamb is provided with recesses or passages 20, corresponding with the number of lugs formed on the door. These recesses open into the jamb, preferably back of the annular step After the door is.

In the present in-.

and into the interior of the safe. These recesses permit the door-locking lugs to pass into position in rear of the body-lugs on the rotation of the door after it is properly seated.

if preferred, the body-lugs 17 could be formed integral with the body, suitable faceplates 17 (see Fig. 7) being bolted to the lugs of the door, for which purpose soft-metal inserts could be located in the lugs of the door, since owing to the organization there is no strain other than a crushing one on these members l7, and consequently they could not be separated from the door by any force tending to pull thedoor outward. In this case also the door may be readily ground to its seat and then the face-plates 17 applied. This permits the safe to be more easily constructed, since the plates 17 can be more readily applied to the door than to the inside of the safebody. To all intents and purposes, owing to the location of the face-plates, they are, so far as separating them from the door is concerned, under an explosive or other force, the same as integral therewith. If preferred, both the lugs proper of the door and body could be provided with the separable face-plates.

From the foregoing it will be seen that whichever construction is used the integral lugs of the door are relatively remote to the opposing integral surfaces or lugs on the bodythat is to say, the opposing locking-surfaces on the door and body are spaced apart and would be ineffective to prevent depthwise movement of the door unless the separable but rigidly or fixedly secured plates were inserted to fill these spaces.

The door will in practice be suitably supported to permit its rotation as, for instance, by means of a crane-hinge pivotally supported to the hinge-lugs of the body (see dotted lines) and pivotally carrying a ring in which the ring (see dotted lines) of the door, formed integral or secured by bolts and soft-metal inserts; will fit and revolvea suitable rack and pinion being used to rotate the door. This mechanism, however, it is not deemed necessary to show, since it does not form a part of my invention.

For preventing rotary movement of the door some suitable means may be used, shown in the present instance as bolting mechanism, comprising a pair of bolts 25, although a greater or less number could be used, if desired. These bolts are supported by a barformed back plate 26, shown in the present instance comprising a pair of cross-bars forming .a cross-shaped member, secured to the flange of the door by suitable bolts projecting into soft-metal inserts 27. If preferred, the ends of these cross-bars could project into recesses formed in the flange. In any event they will serve to give stability to the annular flange should there be any elastic tendency thereof.

The door-locking bolts pass through boltpassages '28 formed in the flange and project into recesses or bolt-openings 29, formed in the jamb of the body, preferably in the rear of the annular steps. The bolts are shown with tapered edges, so that'when shot into the jamb they will completely fill their boltopenings, and thus prevent any lost motion, so that the door could not be rotated backward to open'the joint. For throwing and retracting the bolts some suitable means may be used. In the present instance the bolts are provided with right and left hand threaded shanks 30, carrying at their inner ends a pinion or gear 31, in mesh with a rack 32, to which rack a suitable automatic or time lock may be connected, which, however, it is not deemed necessary to show. When the timethe automatic lock in the usual manner as the door reaches its final position, thereby to throw the bolts and lock the door against rotation.

By providing a dome-shaped door the strain under the action of a ram is more equally distributed and is transmitted to the body in a radial direction and taken up by such body, the arched form of the door preventing it being used as a wedge to open the joint, since it acts, it is believed, to resist the blows of a ram to a greater extent than a door the body of which is fiat, or substantially so. I This form of door need not necessarily be a rotary door.

Whatever bethe formof the meeting surfaces, Whether tapered or .plane surfaces or otherwise formed, it will be seen that the body-surfaces are located in the rear of and away fromthe jambthat is, diverge from such jamb so as to be outside thereof instead of inside of such jamb in the form of radial lugs as heretofore, the complementary surfaces on the door overlapping such body lugs or surfaces, one of the novel features of the present invention being locking surfaces or lugs preferably integral with the-door which overlap, not lugs projecting into the jamb, but the wall of the body or a flange thereof, which wall extends inwardly away from the jamb, lying entirely outside thereof.
