11 Claims.

This invention relates to a bolt structure for safes and the like.

Objects of the invention are to provide simple means capable of easy and ready installation, 1 for converting an ordinary standard slide bolt structure for safes and the like into a re-locking bolt structure; to accomplish the foregoing object without dismantling and taking the safe out of service; to accomplish the foregoing ob- 1 jects by merely removing the old solid metal bolt and replacing it with a bolt designed in accordance with this invention; to provide an inexpensive, simple, and easily installed unitary relocking device for enhancing the safety of 155; ordinary slide bolt types of safes, whether new or used; and to facilitate the safe-workers task of specifying the parts needed to remodel the locking structure of a common slide bolt type of safe.

The foregoing and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

Fig. 1 is an interior view of a safe or depository embodying the invention. Fig. 2 is an enlarged cross-sectional view taken on line 2-2 of Fig. 1 showing the bolt mechanism in a normally operative locked po sition with the relocking mechanism inoperative. Fig. 3 is a view similar to Fig. 2, showing the lock displaced from a normal position, the relocking mechanism being operative to preclude opening of the safe.

Fig. 4 is a cross-sectional view taken on line 44. of Fig. 3.

' Fig. 5 is a view of a modification.

The drawing illustrates a very common type of safe or depository having a body 5 and a door 6, which door carries any ordinary type of lock 49 mechanism 7 that may be'operated, for effecting or permitting reciprocatory movement of a bolt retracting and advancing link or member 9 having a separable connection with the bolt 10. The bolt retract-or 9, by means of any of the well known manually operated keys, handles, or permutation lock dials, may be manually moved for advancing or retracting the bolt 10 only when the lock mechanism is placed in an unlocked condition, as is common practice. In some forms of common locks the retraction of the bolt is effected directly by the dial or key structure, and in others a suitable handle is provided which may be actuated after unlocking of the lock mechanism. The present invention is made in anticipation of the use of. any of the common locks that adapt themselves to use in connection with the means of the invention. The means of this invention is applicable to all types of depositories which require a lock.

Attention is directed to the fact that safes '60; and other depositories, for example, safe de: posit boxes, are commonly made in accordance with the foregoing described construction, and that one of the objects of the present invention is to convert such common type of safe into a more acceptable and satisfactory depository having re-locking bolt features. In outward appearance, the improved locking bolt 10 forming part of the present invention resembles, and is adapted to readily replace, the usual solid metal bolt or bolts which are found in the above mentioned common type of safe. To apply the invention to old safes already in use, or to new unused safes as well, it is necessary only to remove the bolt and replace it by the unitary re- 75, locking replacement bolt structure '10 which is of the same size and the same general appearance as the bolt removed.

Safes such as are above referred to have the door thereof provided with an extending bolt 30 guide or support 13, usually formed by a drilled lug extending from the inner face 14 of the door, adjacent to the outer jamb of the door. In this guide or support, the bolt 10 may be reciprocated longitudinally to engage or disengage the keeper 5 15, which, in some constructions, is provided by the body of the safe or by an opening or a drilled lug (not shown), similar to lug 13, associated with the safe body. The bolt 10 is adapted to be reoiprocated by reason of its connection at 16 with the reciprocating link or bolt retracting member 9. The connection 16 may comprise a locking bolt, pin or lug which is carried by the member-3 and extended through an aperture 17 formed near the rear end of the bolt body.

It is to be understood that the pin 16' has a loose fit within the lateral aperture 17 of the bolt, so that upon forced displacement of the lock mechanism toward 'theinterior of the safe, as indicated in Fig. 3, the pin will recede from the aperture 1'? to initiate functioning of the bolt as a relocking element.

The bolt comprises the shell or body portion 18 which is hollow, and open at its rear end 19. Within the hollow interior of the body portion 18 is disposed a plunger or telescopically arranged projectable member 20, which is urged constantly outwardly toward the'rear end of the bolt body by any suitable means such as a compression spring 21. The spring may have one end thereof 1 seated in a suitable bore 22 provided in member 20, while the other end. abuts the interior of the front end of the bolt. It will be noted that the member 18 is made shorter than the length of the shell bore, so that it may enter the bore and be held in restraint by the pin 16 when in the normal position within the aperture 17. In the event of displacement of the lock mechanism as indicated in Fig. 3, pin 16 leaves the aperture 17 and permits the relocking plunger 20 to spring from the open rear end of the bolt body, so as to strike a suitable abutment 23 which is close enough to the bolt to stop the plunger movement before the compressive force of the spring 21 is spent. As a result of the foregoing action, the bolt body 18 is held in an advanced or locked position by the rearwardly directed force of the plunger upon the abutment 23, and retraction of the bolt thereby is rendered impossible from the exterior.

It is to be understood that the member 9 may support or actuate several pins such as 16, whereby to provide for multiple bolt security.

Although the abutment 23 as herein illustrated and described, is provided by a steel protective plate 24 upon which the locking mechanism is mounted, it is immaterial to the invention whether the abutment is provided by such a plate or by any other substantially stationary part of the safe door. It is considered practical, however, to permit the plunger 20 to abut upon the plate 24 in the manner above set forth, because the plate is secured to the inner face of the door by heavy screws 25 or welds which are accessible only from the interior of the safe. The locking mechanism 7 may be secured to the protective plate by means of screws or the like 26.

In accordance with the modification illustrated in Fig. 5 the relationship of parts is reversed, in

. which case the sleeve or hollow member constitutes the relocking bolt, and the inner plunger 31 serves as the regular locking bolt. The spiral spring 32 functions to constantly urge the plunger and sleeve apart, but the bolt retractor 33 normally precludes such relative movement by reason of its being held, by the pin 34, securely in abutment against both of the members at 35 and 36. Upon inward displacement of the lock casing 37 as hereinbefore set forth, the pin 34 is removed from the opening 38 formed at the rear end of the plunger 31 and the retracter thereby is taken away from the abutments 35 and 36, thus permitting the member 30 to move rearwardly and strike the abutment or plate 39 while the member 31 moves forwardly to strike the abutment 40, just as the member 18 of Fig. 2 strikes its abutment27. Because of the abutting relationship of parts at 3335-36, the assembly constituted of the parts 30, 31, and 32, moves normally as a unit when the operating bar 33 of the lock is actuated.

From the foregoing it should be apparent that we have provided a simple and inexpensive unitary replacement means for converting a common safe into a relocking type safe, which replacement unit may be installed with the use of common tools and without taking the safe out of service. The installer of the device need only to specify the dimension of the bolt guide, whereupon the factory can supply the single unit 10 to replace the removed bolt.

It is to be understood that various modifications and changes in structural details may be made, within the scope of the claims, without departing from the spirit of the invention.

What is claimed is:

1. The combination with a depository having a body provided with a door, a lock mechanism, and an extendable bodily reciprocable slide bolt comprising relatively movable spring-separated parts for bolting the door to the body, of displaceable means associated with the lock mechanism for advancing and retracting the bolt, and means including the displaceable means for precluding relative movement of the spring-separated parts while said displaceable means is in position for retracting the bolt.
