LOGKING MECHANISM FOR SAFES OR VAULTS.

To all whom it may concern:

Be it known that I, SAMUEL W. FISH, a citizen of the United States, residing at Plainfield, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Locking Mechanism for Safes or Vaults, of which the following is a specification.

The present improvement relates to looking means for doors of safes or vaults, and especially for the rotary doors usually held in the jamb by integral holding means such for instance as lugs, the object of the invention being to provide improved means for locking a bayonet joint safe door against rotation, and so organized that the locking bolt will be securely held in its locked position in case the entire mechanism within the chamber of the door be detached from the door.

A further object of the invention is the provision of improved bolt-locking means which is self-locking at the propertime to prevent the door from being rotated when the cooperating lugs of the door and body are in engagement, and which bolt locking means will be automatically operated independently of any time -lock mechanism which may be used, and securely hold the door against rotation, and which cannot be detached from the door, by explosive charges or otherwise, when the door is closed in the safe body.

A further object of the invention is the provision of an improved door locking bolt which is operated by means so located as to be protected from external attack, and which locking bolt will be dogged and unlocked by time-lock mechanism.

A further object of the invention is the provision of improved bolting mechanism effective to hold the bolt in its locked position when the bolt is shot out.

In the drawings accompanying and forming part of this specification, Figure 1 is a rear view of a bayonet joint door provided with this improved locking means; Fig. 2 is a cross-sectional view taken in line aa, Fig. 1; Fig. 3 is a detail view of what I have herein designated as the snubbing mechanism; Fig. 4c is an enlarged view of the main bolt-locking mechanism; Fig. 5 is an enlarged detail view of the snubbing mechanism; Fig. 6 is an enlarged detail Specification of Letters Patent.

view of a part of the bolt mechanism; and Fig. 7 is a detail of one member of the snubbing device.

Similar characters of reference indicate corresponding parts throughout the several figures of the drawings.

In bayonet joint safes, that is, safes provided with looking lugs for holding the door in its jamb, some means has to be provided for preventing the rotation of the door in order to release the door, and various means of this kind have been provided, many such comprising one or more bolts controlled by time-lock mechanism. Frequently this locking-bolt mechanism has been controlled by an automatic, but the bolt is connected therewith and is entirely controlled thereby to shoot the bolt into its locking position. In the present improvement this automatic is entirely done away with. and the construction is such that the bolt is self-locking, time-lock mechanism being used merely to insure the dogging and retraction of the bolt, and not its projection.

The door 2, which may be of any suitable construction, usually of an integral structure, is shown in the present instance as comprising a body 3 and a rearwardly extending flange 4 having a series of looking lugs 5. In one of these lugs 5, shown as the uppermost lug when the door is in its locked position, an opening 6 is provided for the reception of an insert 7 of machineable metal, this being desirable when the door is made of unmachineable metal. This insert 7 is securely seated within the opening in the lug and is provided with a bolt opening 8 having a shoulder 9, cooperating with the under side or shoulder of the bolt head and so prevent the locking bolt from being forced inwardly toward the center of the door when the door is closed, by means of an external attack with explosives or otherwise. This insert is also provided adjacent to its lower end with an annular step or shoulder 11, which forms a base for the bolt-operating or looking spring 12.

The bolt comprises a head 10 which in its unlocked position engages the upper shoulder 9 and is provided with a shank 13 running through a sleeve 14, the upper end of which sleeve has a flange 15 between which and the shoulder 11 at the lower end of the insert 7 a spring-receiving chamber 16 for the spring 12 is formed. The flange 15 of the sleeve operates to compress the spring at the proper time to permit the retraction of the bolt. Attached to the inner end of the sleeve 14 is a sleeve-guide 17. This guide is attached to the sleeve by means of an interiorly threaded sleeve or projection 18, which is provided with a locking screw 19 extending therethrough and through the sleeve and projecting into a slot 20 of the bolt, thus preventing the turning of the sleeve and of the bolt independently of each other. This locking screw also prevents the bolt from being withdrawn in any manner when the door is open. This sleeve-guide 17 is slotted at its inner end, as at 21, to straddle a stud 22 secured to a back plate 23 located within the flange of the door in any suitable manner. This stud prevents the turning of the guide and maintains the sleeve of such guide and the locking bolt in proper alinement.

Mounted on the stud 22 is the bolt retracting or driving member 30 and the bolt dogging member 40, being held in position on such stud by a nut 25. The bolt retracting or driving member 30 is provided with a projection 31 in position to contact with a projection 24 on the sleeve guide at a predetermined period. This driving member is also provided with a recess 32 into which the time-lock actuating member or lever 51 extends. This bolt-retracting member is also provided with another recess 83 which controls the tripping or snubbing mechanism. The dogging member 40, which, like the bolt-retracting member, is in the form of a disk, is provided with a pair of recesses, one, as 41, for the reception of the lower end of the door-locking bolt when the latter is in its unlocked position, and the other, as 42, for the reception of the time-lock lever 51, which time-lock lever or actuator is connected with a suitable time lock 50 carried by the back plate 23. Attached to the hub of the dogging member 40 is a suitable spring 43, one end being securely attached to the hub of such dogging member and the other end to a pin 44 on the back plate 28. This pin projects through an enlarged or elongated opening 44 of the driving member 30. The object of this spring is to maintain the edge of the recess 41 for the locking bolt against the lower end of the locking bolt when the latter is unlocked and to rotate the dogging disk or member into position under the lower end of the locking bolt when the bolt is in its locked position, thereby to dog the'locking bolt securely until the dogging member or disk is withdrawn by the time-lock lever in the manner hereinafter described.

From the foregoing it will be observed that the time-lock actuator or lever 51 transmits power to the driving memberor boltretracting member 30, which, through the medium of its projection 31, retracts the sleeve guide and sleeve against the action of the bolt spring and thereby compresses the bolt-locking spring 12. At the same time the time-lock actuator also shifts the dogging member to bring its recess 41 into position below the lower end of the bolt, so that when the time lock is at zero this recess will be in the position indicated in Figs. 1 and 4, and will then permit the bolt to fall by gravity into such recess in the dogging member and thus into its unlocked positionf In order, however, to prevent the locking bolt from being shot outwardly prematurely, as

for instance when the door is open and the time lock is being wound, and until the door is properly closed, it is necessary to provide a tripping or snubbing mechanism 60, which in the present instance comprises a pair of members, one an arm 61 and the other a catch 62, mounted on a stud 63 se cured to the back plate. The adjacent hubs 64 and 65 of the arm and catch are clutch-faced, that is to say, they are formed as clutch members. Around the hub 64 is located a spring 66, the free end of which is attached to the pin 44 hereinbefore mentioned.

In setting the mechanism, the time lock is first wound for the given number of hours, whereupon the bolt-locking spring 12 immediately attempts to force the locking bolt into its locked position, but is prevented from accomplishing this by the operation of the catch 62 engaging the end 67 of the sleeveguide, which is specially formed for this purpose. This operation takes place while the time lock is traveling from its unlocked to its locked position, so that it will be seen that although the locking bolt and its sleeveguide are only partially advanced from unlocked toward locked posit-ion the time-lock lever or actuator and the driving or bolt retracting member have assumed a locked position. This organization is necessary since the time lock must be set when the door is open, but the bolt must not be protracted at this time, for this would prevent the door from being inserted into its jamb.

The driving member or bolt retractor 80 has, as hereinbefore stated, a recess 33 having a cam surface. The spring 66 carried by the hub 64 tends to hold the lower end of the arm 61 in engagement with the periphery of the driving member or bolt retractor 30. As this driving member or bolt retractor 30 is rotated by means of the timelock lever or actuator 51 during its travel to its locked position the recess 33 comes into position opposite the lower end of the snubbing arm 61 and the spring 66 has a tendency to cause the lower end of the arm 61 to enter said recess, this, however, being prevented by the catch face 62 engaging the part 67 of the sleeve-guide. The purpose of this recess 33 is to permit the catch 62 to release the sleeveguide at the proper time.

lVhen the time-lock is wound and the door is closed the locking bolt 10, which, as will be observed, is provided with an inclined or beveled end, projects slightly above the door joint and consequently will strike the jamb of the body when closing, and thereupon, owing to its inclined surface, be forced into the bolt-receiving opening of the door as far as possible, thus forcing inwardly the sleeve-guide to a suflicient extent to carry the part 67 thereof away from the catch (32, whereupon the spring 66 will immediately throw the lower end of the arm 61 into the recess 33 and consequently the catch 62 away from the sleeve-guide 67, so that when the door is revolved to its proper locked position and the bolt 10 is thus brought opposite the bolt hole in the jamb of the body its locking spring 12 will then immediately and automatically force the locking bolt 10 into such bolt hole and in position to lock the door against rotation, this action of the bolt being entirely effected by the spring 12 without any automatic or other motor mechanism for protracting the bolt. It will also be observed that this spring 12, which constitutes the operating means for protracting the bolt and holding it in its jamb, is entirely concealed within the flange or lug of the door and thereby protected from external attack. As the bolt 10 assumes its locked position to prevent rotary movement of the door the dogging member 410 is, by means of its spring 13, rotated on its stud to bring the periphery of such dogging member under the lower end of the bolt and at the same timecarry one wall of its recess 42 into engagement with the time-lock lever 51 to be operated thereby when such time lock runs down. Thus the locking bolt 10 is dogged securely and prevented from being retracted even should the spring 12 be compressed prematurely.

The retraction of the bolt 10 is accomplished in a way by gravity, but such retraction is under the control of the time lock. When the time lock runs down its actuator 51 causes the driving member or bolt retractor 30 and the dogging member 40 to rotate on their stud 22. The driving member or bolt retractor 30 in rotating causes the projection 31 to shift or depress the sleeve-guide 17 and sleeve, and thereby compresses the bolt-locking spring 12, so that such spring is no longer effective to force the bolt into the bolt opening of the jamb of the safe body. But the bolt at this time cannot retract, because the dogging member 10 has its periphery still in osi tion below or under the lower end of the bolt- 10. hen, however, this dogging member 40 has been rotated also by the actuator 51 of the time lock to carry its recess .1 into position in juxtaposition to the lower end of the bolt, then, as the bolt is no longer dogged, it will drop by gravity so that the lower end of such bolt may enter the recess and the door be released to permit rotary movement. At this time the driving or boltretracting member 30, in rotating, forces, by means of the cam surfaced recess 33, the snubbing arm 61 outwardly and consequently the catch 62 thereof inwardly into position to engage the part 67 and so snub or temporarily lock the locking bolt against protraction and permit the time lock to be wound up in the manner hereinbefore described when the door is open. In practice other means could be used for shooting or protracting the bolt and the spring 12 utilized as the means for holding the bolt protracted, in which case the bolt-retracting means would be somewhat more powerful than the spring 12 so as to retract the bolt against the tension of the spring, as illustrated in my pending application Serial hlo. 5 18, 186, filed March 10, 1910.

From the foregoing it will be observed that one of the features of the present improvement is an automatically shifting lock ing bolt, in combination with suitable means for preventing the shifting of the belt at a predetermined period and effective to release the bolt on a slight endwise shifting of the bolt itself. In other words, the snubbing device 60 is effective to prevent premature shifting of the bolt both during the winding of the time lock and also until the door is properly seated in its jamb, which snubbing mechanism is in turn operated bv a slight inward shifting of the bolt itself as the door is seated in its jamb; that is to say, the bolt automatically operates to release itself, thereby being selfreleasing.

Another feature of the present improve ment is that the locking bolt, being provided with a shoulder, prevents it from passing through the bolt hole into the chamber of the door under certain conditions.
