Safe
A safe (also called a strongbox or coffer) is a secure Lock (security device), lockable box used for securing valuable objects against theft or fire. A safe is usually a hollow cuboid or cylinder, with one face being removable or hinged to form a door. The body and door may be Casting (metalworking), cast from metal (such as steel) or formed out of plastic through blow molding. Bank teller safes typically are secured to the counter, have a slit opening for dropping valuables into the safe without opening it, and a time-delay combination locks, time-delay combination lock to foil thieves. One significant distinction between types of safes is whether the safe is secured to a wall or structure or if it can be moved around. A less secure version (only suitable for petty cash) is usually called a cash-box. History The first known safe dates back to the 13th century BC and was found in the tomb of Pharaoh Ramesses II.

Safe-cracking
Safe-cracking is the process of opening a safe without either the combination or the key. Physical methods Different procedures may be used to crack a safe, depending on its construction. Different procedures are required to open different safes, so safe-crackers need to be aware of the differences. Lock manipulation Lock manipulation is a damage-free combination recovery method and a well known surreptitious bypass technique. Manipulation only requires fingers, eyes, and proper technique, though it is a skill that takes years to develop. While manipulation of combination locks is usually performed on Group 2 locks, many Group 1 locks are susceptible to manipulation. It involves the manipulation of the lock in order to obtain the combination one number at a time. Manipulation procedures can vary, but they all rely on exploiting the presence of mechanical imperfections in the lock, unlocking the safe and recovering its combination, which can then be reused to open the safe loc ...

Diversion Safe
Concealment devices or diversion safes are used to hide things for the purpose of secrecy or security. They are made from an ordinary household object such as a book, a soda can, a candle, a can, or something as small as a coin. The idea is that such an inconspicuous object would not be expected to contain anything of worth. Examples in espionage include dead drop spikes for transferring items to other people, and hollowed-out coins or hollowed out teeth for concealing something - such as microfilm or a suicide pill. Examples in smuggling include suitcases with false bottoms for hiding contraband. During World War II MI9 was responsible for creating many concealment devices for "escape aids" to assist prisoners of war to escape. Examples Ammunition Starting in the First World War and still continuing today, military personnel use ammunition casings to hide small amounts of critical information e.g. encryption/recognition codes or navigational grid references etc. The hid ...

Door
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate lockin ...

Combination Lock
A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or ''cams'', by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an electronic or mechanical keypad. Types range from inexpensive three-digit luggage locks to high-security safes. Unlike ordinary padlocks, combination locks do not use keys. History The earliest known combination lock was excavated in a Roman period tomb on the Kerameikos, Athens. Attached to a small box, it featured several dials instead of keyholes. In 1206, the Muslim engineer Al-Jazari documented a combination lock in his book ''al-Ilm Wal-Amal al-Nafi Fi Sina'at al-Hiyal'' (''The Book of Knowledge of Ingenious Mechanical Devices'').Paul VallelyHow Islamic Inventors Changed the World ''The Independent'', 11 March 200 ...

Time-delay Combination Locks
A time-delay combination lock is most commonly a digital, electronic combination lock equipped with a delay timer that delays the unlocking of the lock by a user-definable delay period, usually less than one hour. Unlike the time lock, which unlocks at a preset time (as in the case of a bank vault), time-delay locks operate each time the safe is unlocked, but the operator must wait for the set delay period to elapse before the lock can be opened. Time delay safes are most commonly used in businesses with high cash transactions. They are used in some banks including Nationwide, HSBC, Barclays, and Halifax. Use Time-delay combination locks are frequently incorporated into money safes as an armed robbery deterrent. In many instances, time-delay combination locks are also equipped with a duress code which may be entered to activate the time delay whilst sending a silent alarm to a monitoring centre. Modern time delay combination locks can have many functions such as multiple diffe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (security Device)
A lock is a mechanical or electronic fastening device that is released by a physical object (such as a key, keycard, fingerprint, RFID card, security token or coin), by supplying secret information (such as a number or letter permutation or password), by a combination thereof, or it may only be able to be opened from one side, such as a door chain. A key is a device that is used to operate a lock (to lock or unlock it). A typical key is a small piece of metal consisting of two parts: the ''bit'' or ''blade'', which slides into the keyway of the lock and distinguishes between different keys, and the ''bow'', which is left protruding so that torque can be applied by the user. In its simplest implementation, a key operates one lock or set of locks that are keyed alike, a lock/key system where each similarly keyed lock requires the same, unique key. The key serves as a security token for access to the locked area; locks are meant to only allow persons having the correct key ...

Charles Chubb (businessman)
Charles Chubb (1779 – 1846) was an English lock and safe manufacturer. Life Born in Fordingbridge, Hampshire, he trained as a blacksmith who started a hardware business at Winchester then moved to Portsea, Portsmouth. Here he improved on the "detector" lock, originally patented in 1818 by his brother, Jeremiah Chubb. He soon moved to London and then to Wolverhampton, where he employed 200 workers. In 1835, he patented a process intended to render safes burglar-proof and fireproof, and subsequently established a large safe-factory in London. He died on 16 May 1846, and was succeeded in the business by his son, John Chubb (1816–1872), who patented various improvements in the products of the firm and largely increased its output. The factories were combined under one roof in a model plant and the business grew to enormous proportions, now Chubb Locks. Charles Chubb was buried on the 22 May 1846 in the western side of Highgate Cemetery Highgate Cemetery is a place of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chubb Locks
Chubb Locks is a former brand name (expired 2010) of the Mul-T-Lock subsidiary of the Assa Abloy Group, which manufactures locking systems for residential, secure confinement and commercial applications. History Chubb was started as a ship's ironmonger by Charles Chubb in Winchester, England, and then moved to Portsmouth, England, in 1804. Chubb moved the company into the locksmith business in 1818, in Wolverhampton. The company worked out of a number of premises in Wolverhampton, including the purpose-built factory on Railway Street, now still known as the Chubb Building. His brother Jeremiah Chubb then joined the company, and they sold Jeremiah's patented detector lock. In 1823, the company was awarded a special licence by George IV, and later became the sole supplier of locks to the General Post Office, and a supplier to Her Majesty's Prison Service. In 1835, they received a patent for a burglar-resisting safe, and opened a safe factory in London in 1837. In 1851, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time Lock
A time lock (also timelock) is a part of a locking mechanism commonly found in bank vaults and other high-security containers. The time lock is a timer designed to prevent the opening of the safe or vault until it reaches the preset time, even if the correct lock combination(s) are known. Time locks are mounted on the inside of a safe's or vault's door. Usually there are three time locks on a door. The first one to reach 0 will allow access in to the vault; the other two are for backup purposes. Time locks were originally created to prevent criminals from kidnapping and torturing the person(s) who knows the combination, and then using the extracted information to later burgle the safe or vault, or to stop entry by authorized staff at unauthorized times. An early test of their effectiveness came on May 29, 1875 in Great Barrington, Massachusetts, when a gang of robbers took the family of banker Frederick N. Deland Frederick Nelson Deland (December 25, 1843 – August 23, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
