Safe
A safe (also called a strongbox or coffer) is a secure 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 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 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. It was made of wood and consisted of a locking system resembling the modern pin tumbler lock. In the 16th century, blacksmiths in souther ...

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 lock ...

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 locking ...

Wolverhampton
Wolverhampton () is a city, metropolitan borough and administrative centre in the West Midlands, England. The population size has increased by 5.7%, from around 249,500 in 2011 to 263,700 in 2021. People from the city are called "Wulfrunians". Historically part of Staffordshire, the city grew initially as a market town specialising in the wool trade. In the Industrial Revolution, it became a major centre for coal mining, steel production, lock making, and the manufacture of cars and motorcycles. The economy of the city is still based on engineering, including a large aerospace industry, as well as the service sector. Toponym The city is named after Wulfrun, who founded the town in 985, from the Anglo-Saxon ''Wulfrūnehēantūn'' ("Wulfrūn's high or principal enclosure or farm"). Before the Norman Conquest, the area's name appears only as variants of ''Heantune'' or ''Hamtun'', the prefix ''Wulfrun'' or similar appearing in 1070 and thereafter. Alternatively, the city ma ...

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, they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. His plot (no.1847) is in the dissent ...

Jeremiah Chubb
A Chubb detector lock is a lever tumbler lock with an integral security feature, a re-locking device, which frustrates unauthorised access attempts and indicates to the lock's owner that it has been interfered with. When someone tries to pick the lock or to open it using the wrong key, the lock is designed to jam in a locked state until (depending on the lock) either a special regulator key or the original key is inserted and turned in a different direction. This alerts the owner to the fact that the lock has been tampered with. Any person who attempts to pick a detector lock must avoid triggering the automatic jamming mechanism. If the automatic jamming mechanism is accidentally triggered (which happens when any one of the levers is lifted too high) the lock-picker has the additional problem of resetting the detector mechanism before the next attempt to open the lock. This introduces additional complexity into the task, increasing the degree of lock-picking skill required to a le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 hidi ...

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 to ope ...

Electronic Lock
An electronic lock (or electric lock) is a locking device which operates by means of electric current. Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to the lock. Electric locks may be connected to an access control system, the advantages of which include: key control, where keys can be added and removed without re-keying the lock cylinder; fine access control, where time and place are factors; and transaction logging, where activity is recorded. Electronic locks can also be remotely monitored and controlled, both to lock and to unlock. Operation Electric locks use magnets, solenoids, or motors to actuate the lock by either supplying or removing power. Operating the lock can be as simple as using a switch, for example an apartment intercom door release, or as complex as a biometric based access control system. There are two basic types of locks: "preventing mechanism" or operation mechanism. Types Electromagnetic lock The mos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
