To all'whom it may concern:

Be it known that 1, CHARLES Salt Lake City, in the county of Salt Lake and State of'Utah, have invented certain new and useful Improvementsin- Safe Locks, of which the following is =a-speciiication.

My invention relates to locks for -safes and vaults, and has for its-object to provide an auxiliary lockor fastening means for safes and vault doors, whichare locked with my auxiliary lock by the custodian when the door isclos'ed, and which will be further automatically locked by any attempt to force the'auxiliary combination look from the out side. A further object is to provide on safe and vault doors, having horizontally or vertically movable locking bars which engage the sides and endsof the'safeor vault when the bolt bars are 'set, :an auxiliary combination lock b which any one or more of said bars may e locked andheld'from movement. A'further object is to improve the present fastening of vault and safe doors by providing means for locking the bolts of said present fastenings with an auxiliary lock of the'combination type which automatically set to engage said bolts at any attempt to force said'auxilia'ry look from the outside of said vault. v l

These objects I accomplish with the device illustrated in the accompanying drawings in which similar letters and numerals of reference indicate like parts throughout the several-views and as described in the specirticationforming apart of thisapplication and pointed out in the appended claii'ns.

In the drawings in which 1 have shown a substantial embodiment of my invention, Figure l is anelevation of the inside of'the va'ult door in a locked positioinand with the fastening bolts engaged by my auxiliary 'lock. -Figure 2 is a view of aportion of :the same door with the bolts showuinunlocked position'and with my auxiliarylockmeans. Fignot engaged with the fastenin ure 3 is an elevation of a portion of the outside of said door with the auxiliary combination lock in place thereon in addition to the regular lock. Figure 4: IS a view partly in section of one of my locks in place on'one of the fastening bolts and after it has been engaged with said bolt after attempted A. Fownnm a citizen of the United States, residing at burglary. Figure 5 is another view showing the fastening means as they appear when fullyset by an attempt to break my auxili ary lock. Figure :6 is a view partly in section of the other bolt fastening means. F

ures

4, 5 and 6 are somewhat enlarged ..ela-

tive to the other figures The fastening means now used on most safe and vault doors consists of bolts which are moved longitudinally by a lever and which are set against such. movement by a combination lock that isoperable by any person knowing the combinatioinand frequently set so that itcan not be worked before a time limit as well. 'Burglars knowing the construction of such locks andbolts frequently drill holes in the door adjacent the lock, sever the connection between the said'lock and the bolts, or by means ofpunches from outside the door they destroy the lock and can then operate the lever-and move the fastening bolts or shafts as they are sometimes called. invention is to provide another combination lock which is secured on the door and by which any one or moreof said bolts or shafts may be secured against the movement required to open the door. This auxiliary locking of said bolts maybe accomplished and operated by the person whose duty it is to lookthe safe or vault, or if such person should fail or neglect to operate and set said auxiliary lock, and any attempt-be made to destroy the auxiliary look from outside the vault my improved lock will be automatically set and none of said bolts may be thereafter moved or the door be opened without its destruc- 'tion,'a-nd, furthery-the--particular bolt or shaft with which my auxiliary lock is used may be changed from time to time as desired and its connection with any particular one or more of said bolts can not be determined or ascertained from outside the safe or vault, so that the connection can be destroyed from any one operating outside the vault, and the connections are purposely made to differ when two or more are used so that they may not be destroyed or moved by any one not knowing the combination of the auxiliary lock, whether that person works from 'inside' or outside the safe or vault. This is accomplished bythe use of the cylinder lock shown in Figure 4:.

til

My improved locking means consists of a combination look A, with any desired number of tumblers, and which is secured in a hole in the door of the safe or vault. On the inner end of said lock is fastened a disk 1 having one or two laterally projecting pins 2 on. its inner face. A metal frame B is secured to the inner face of the door C and through which frame B is bored opc-nings in which is operatively carried the fastening bolts D. The said bolts D are moved simultaneously by the lever E which moves the cross piece F, and by the bell-crank levers G which are moved by two of said bolts D. On the inner face of said frame 13 is provided two bearing or guide sleeves 4: and 5, and within which are operated the

locking bars

6 and 7. The said locking bar 6 is moved by the lever 8 with and by the link bar 10, while the locking bar 7 is moved by the lever 9 which is connected with said disk 1 by the link bar 11. A spring 12 is connected at one end to the lever 8 and at its other end to the said door C to automatically further move the locking bar 6 when the lock A or any of the members 8, 9, 10 or 11 are injured. Another spring 13 is used to similarly operate the locking bar T and set the catch pin 22 provided in locking bar 7 7 when look A or bars 8, 9, 10 or 11 are injured or destroyed. It is obvious that similar locking bars may be provided for on any of said fastening bolts D as desired, by slight changes in the levers and link bars connecting said bolts with said disk 1. The said locking bar 6 is bifurcated at one end, as shown in Figures & and 5, and on one prong shown at 1 1 a lock case H is provided within which is operated a cylinder lock having a number of tumblers 15 which are operated by a key 16. A spring bolt 17 is provided in said case H to automatically move longitudinally and thereby engage in a recess 18 which is cut in the adjacent fastening bolt D to lock said locking bar 6 in its engagement with said fastening bolt D. The locking bar 7 is to engage the fastening bolt D adjacent thereto by being carried in or passed through a hole cut in said bolt D.

The operation of locking any safe or vault door is as follows The keeper of the safe or vault closes the door and fastens it in place by moving the usual lever E. The common lock used for locking the safe, shown at K, is then set to lock said cross piece F, and by operating the combination lock K the safe is locked against any opening thereof except by burglars. As previously stated, a burglar may drill a hole through the door adjacent the racking or connecting bar 21 and saw off said bar, and if that is the only fastening means used, all the burglar will have to do after sawing said bar 21 is to move the lever E and thereby open the vault. Or he may punch out the said lock K and thereby destroy the said racking or connecting bar 21 and its engagement with said cross piece F, when the safe may be opened, as before stated. However, if my invention is used on said vault and the combination lock A is set and the

locking bars

6 and 7 are engaged as shown in Figure 1, and an attempt is made to destroy the said lock A or lovers 8 or 9, said attempt will move the links 10 and 11 from off the pins 2 and their

respective springs

12 and 13 will automatically further move the locking bars (3 and 7 and allow the respective fasteners, pins 17 and 22, to trip, thereby further locking my device, which can not then be opened except by use of the key 16. The adjacent fastening bolts D can not be moved longitudinally until the key 16 is used and the spring bolt 22 is operated, both of which must be moved and unlocked from inside of the vault. And even though a hole be cut in the door large enough for the burglar to enter he musthave the key and operate the cylinder lock shown in Figure 4 before lie-can open the door. The tire doors provided between the vault and safe doors can not be opened far enough for entrance to vault except after the outside door has been fully opened. This is one ofthe purposes of providing the cylinder lock, shown in Figure 4.

Having thus described my invention and its operation, I desire to secure by Letters Patent and claim 1. In an auxiliary lock for safe doors the combination of longitudinally movable bars slidably carried on the door and adapted to engage the walls of the safe. of a combination lock secured in said door: a disk secured on the inside of said lock; links connected therewith and pivoted to spring actuated levers; locking bars adapted toengage with said longitudinally movable bars and each of said locking bars pivoted to its respective lever, whereby said locking bars will be moved longitudinally and engage said longitudinally movable bars when the said links are disengaged from said disk; and means to release said locking bars when said safe door is fully opened.

2. In an auxiliary lock for safe doors the combination with longitudinally movable bars slidably carried on the inner side of said door, of a combination lock secured in said door; a disk on the inner end of said lock; laterally projecting pins on said disk; locking bars adapted to engage with said longitudinally movable bars; levers pivoted on said locking bars and connected with said pins on said disk; and springs to throw said locking bars when the levers are disengaged from said disk.

3. A safe door lock comprising longitudinally movable bars having transverse openings therein; locking bars carried in guide sleeves and adapted to engage in said lransverse openings in said movable bars; levers fulcrumed on the inner face of said door, one end of each operatively connected to its respective locking bar and the other end operatively connected with said lock; and

a spring for each lever to engage the 1CSP9C tive locking bars and longitudinally movable bars when said lock is destroyed.

In testimony whereof I have affixed my signature.
