SAFE-DEPOSIT VAULTS

 THE SAFE DEPOSIT COMPANY OF NEW YORK 



A3UT 10,000 square feet of the basement of 

 the Singer Building is specially designed and 

 constructed for the use of The Safe Deposit 

 Company of New York, which offers its patrons the 

 most secure, elaborate and convenient means for the 

 safe keeping of valuables. 



Although every facility is afforded the box holder 

 or the vault lessee for easy access to his or her prop- 

 erty, its private examination and the transaction of 

 business, no similar opportunity is possible to an un- 

 authorized person. 



During nearly fifty years' experience this Com- 

 pany has never had a loss of property intrusted to 

 its care. 



In order to secure the best vaults, the services of 

 The Hollar Company, Engineers, Designers and 

 Superintendents of Bank- Vault Con- 

 struction, were retained for the 

 purpose of making the plans and 

 specifications; also to superintend the construction 

 of the work in the factory and its erection in the 

 building. 



Ten Fire- and Burglar-Proof Vaults have been in- 

 stalled. Two of the largest of these vaults are for 

 general safe-deposit purposes and are of the round 

 door type. In selecting the material to be used in the 

 construction of all the vaults, consideration was given 



[11*] 



to the physical properties of that metal which would 

 offer the greatest resistance to penetration. 



The vaults and doors are formed of layers of five- 

 ply welded and hardened Chrome Steel and Iron and 

 Open Hearth Steel in alternate layers, joined together 

 in the strongest manner possible from the inside 

 with threaded bolts of welded, twisted and hardened 

 strd and iron. The door of the largest of the 

 Safe-Dej>osit Vaults weighs over 16 tons and is 

 grounded like a valve to an absolutely air-tight joint 

 in order to preclude the introduction of liquid or other 

 explosives. 



The locking bolts of this door radiate from the 

 center, after the manner of the spokes in a wheel, and 

 are operated by a specially designed motor, which i^ 

 in turn checked and controlled by an electrically 

 winding time lock. All of this mechanism is con- 

 trolled without connection or holes through the doors. 



Should conditions arise, however, which would, 

 in the opinion of the custodian of the vault, justify 

 keeping the vault locked for any additional number of 

 hours beyond the time for which it was originally set, 

 this can be accomplished without opening the vault 

 door, or without any one having access to the locks. 

 The value of this feature will be appreciated when the 

 contingency of fire or riot is considered, for in either 

 case it would be undesirable to permit the unlocking
