SAFE OR VAULT DOOR.

Application filed September 11, 1923. Serial No. 662,049.

This invention relates to safes and vaults, and more particularly relates to safe. or vault doors, and especially to doors which are useful for emergency entrance.

The provision of emergency doors in safes and vaults is becoming more popular, due to the fact that there is an increased desire for means whereby access may be had to a safe or vault in case of emergency. Emergency entrances are also desirable and useful for purposes of ventilation. it is desirable that an emergency door he burglar-proof, and yet be readily responsive in the hands of an authorized person, and at the same time be reasonably inexpensive to construct and install in a safe or vault.

The principal object of our invention is to provide a safe or vault door which is burglar-proof, yet readily operable by an authorized person, and at the same time is comparatively inexpensive to construct and to install in a vault or safe.

A further object of our invention is to provide a door of the'above character which is especially suitable for use as an emergency entrance to the safe or vault.

A further object of our invention is to provide novel and improved locking mechanism for the door.

Other objects of this invention will be in part obvious and in part pointed out hereinafter. 1

In accordance with our invention, we provide a circular door, preferably carrying lock mechanism including combination and time features, the door being provided with a circular bolt-frame adapted to cooperate with a revolvable locking ring mounted on the vestibule, which ring, in accordance with its position, locks and unlocks the door, and means are provided which are operable from the exterior of the door for moving the revolving locking ring on the vestibule into and out of locking position.

l-leretofore, the standard type of emergency doors requires square frames or vestibules. Such frames involve more expensive construction than do circular frames. Moreover, in such constructions, the accessible means for operating the bolt-work mechanism has been located on the vestibule jamb. In our construction, such means are located on the door, thus eliminating the expense of locating these means in the vestibule jamb.

In order that a clearer understanding of our invention may be had, attention is hereby directed to the accompanying drawings, forming a part of this application and illust-rating one possible embodiment of; our invention.

Referring to the drawings Fig. 1 is a plan view of a door embodying our invention, showing a portion of the vestibule jamb with the door unlocked;

Fig. 2 is a sectional view of a part of the door and vestibule jamb, and is taken on the line 22 of Fig. 1;

Fig. 3 is a perspective view of a portion of the door and vestibule jamb, the door being unlocked; and

Fig. 1 is a perspective View of a fragment of the door, showing in full lines the locking dog in unlocked position, and showing in dotted lines the locking dog in locked position. i

Similar reference characters refer to similar parts throughout the several views of the drawings.

On the rear of the door 1 are assembled suitable combination lock mechanisms, diagrammatically shownat 2 and 3, and a time lock mechanism, diagrammatically shown at 4. These look mechanisms are connected together by a link 5, which in turn is connected by a link 6 to the middle of a lever arm 7, which is pivoted at one end to the door, as at 8, and which at its other end, as at 9, is pivoted to a locking lug 10. Looking lug 10 is suitably mounted and guided in the door, and its function is to prevent or allow movement of a segment 11 from looking position to unlocking position. To this end, segment 11 is mounted on the door for slidable movement across an end of lug 10 when lug 10 is in retracted or unlocked posi tion, and the arrangement being such that, when segment 11 is in locked position, lug

10 may be moved into locking position across an end of segment 11. This will prevent movement of segment 11 into unlocked position until lug 10 has been-retracted to allow segment 11 to move by. Segment 11 is movable into and out of locking position from a handuvheel 12, which is at the outside of the door, beingmounted on the end of a shaft 13, which is journaled in the door, shaft 13 at its inner end having a pinion li which is constantly in mesh with teeth 15 provided on segment 11. Segment 11 also carries a locking dog 16, which extends outwardly and is permanently engaged in a recess 17 provided therefor in one of the holding lugs 18, which constitute a part of a locking ring 19. Ring 19 may be held .revolvably in place on the vestibule 20 by turning out a rabbet 21 in the vestibule, and forming a retaining groove for the ring 19 by securing circular box plates, such as 22, to the vestibule behind the ring 19. WVhen locking ring 19 is moved to locked position, its lugs 18 are moved into locking engagement behind cooperating lugs 23 provided on the door, and when looking ring 19 is moved into unlocked position, its locking lugs 18 align with recesses between the lugs 23 of the door, permitting the door to be opened. Suitable spring detents 24 may be provided in the vestibule jamb to yieldingly maintain the locking ring 19 in adjusted position. To permit movement of locking dog 16 into and out of locking position, the bolt-frame 25 of the door is suitably slotted, as at 26.

In combination with the above, there may be provided a day-gate 27 and a glass frame 28 .of usual constructions. The vestibule jamb 20 may be secured to the wall 29 of thevault or safe by any suitable means, and about the front of the vestibule there may be provided an architrave 30, and at the .rear of the frame there may be provided a flange bar 31.

The operation-of the door and locking mechanism will be apparent from the above description. When the locking lug 10 is in unlocking position, as shown in Fig. 1, the door may be locked and unlocked by merely rotating the handle 12, on account of the connection between pinion 1 1 with teeth 15 of segment .11, which in turn is in engagement with locking ring 18 through locking dog 16 and recess 17. When segment 11 has .or time lock been removed into locking position through operation of hand-wheel 12, movement of looking lug 10 into position across the end of the segment, by means of the combination mechanisms, will prevent the movement of segment 11 into unlocking position, either by means of hand-wheel 12 or otherwise, and will thus prevent the unlocking of the door until locking lug 10 has been retracted by the combination and time lock mechanisms.

As many changes could be made in the above construction, and as many various embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings be interpreted as il lustrative and not in a-limiting sense.

What we claim is 1. The combination with a vestibule jamb and a door fitting the jamb, of locking means on the door, coacting locking means movably carried on the jamb, and means carried on the door, for moving the locking means on the jamb when the door is closed into and out of locking coaction with the locking means on the door.

2.
