Chubb Detector Lock
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] |

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.

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.

Protector Lock
The term protector lock has referred to two unrelated lock designs, one invented in the 1850s by Alfred Hobbs, the other in 1874 by Theodor Kromer. Hobbs' protector lock The Protector lock (also called the "moveable lock") was an early 1850s lock design by the leading American locksmith Alfred Charles Hobbs, the first man to pick the six-levered Chubb detector lock, at the Crystal Palace Exhibition in 1851. That lock was created with the intent of being a lock that could not be picked. Before Hobbs and his revolutionary lock designs, locks were opened by means of a series of false keys, in a process that could take an extremely long time. If the series was not properly completed in the lock, and the combination not completely correct, the lock could not be defeated. This design was accepted as quite unbreakable until Hobbs was able to pick them, using very fine and careful manual dexterity, applying a certain level of pressure on the bolt while manipulating each lever in t ...

Alfred Charles Hobbs
Alfred Charles Hobbs (October 7, 1812 – November 6, 1891) was an American locksmith and inventor. He was born in Boston, Massachusetts, in 1812; his father was a carpenter. He married Charlotte F. Nye (1815-?) of Sandwich, Massachusetts, in 1835 and had four children: Charlotte Hobbs, Alfred J. Hobbs (1843-?), Mary H. Hobbs, and Arthur Hobbs. Both of his parents were born in England. Life Hobbs went to London as a representative of the New York company of Day & Newell, which was exhibiting at the Great Exhibition of 1851. Hobbs had brought with him his boss's (Robert Newell) Parautoptic lock, designed to compete with, and surpass, the locks available at the time in Britain. He was the first one to pick Bramah's lock and the Chubb detector lock at the Great Exhibition of 1851 and forced lock manufacturers to improve their designs. The lock controversy continues a subject of great interest at the Crystal Palace, and, indeed, is now become of general importance. We belie ...

Guinea (British Coin)
The guinea (; commonly abbreviated gn., or gns. in plural) was a coin, minted in Great Britain between 1663 and 1814, that contained approximately one-quarter of an ounce of gold. The name came from the Guinea region in West Africa, from where much of the gold used to make the coins was sourced. It was the first English machine-struck gold coin, originally representing a value of 20 shillings in sterling specie, equal to one pound, but rises in the price of gold relative to silver caused the value of the guinea to increase, at times to as high as thirty shillings. From 1717 to 1816, its value was officially fixed at twenty-one shillings. In the Great Recoinage of 1816, the guinea was demonetised and the word "guinea" became a colloquial or specialised term. Although the coin itself no longer circulated, the term ''guinea'' survived as a unit of account in some fields. Notable usages included professional fees (medical, legal, etc.), which were often invoiced in guineas, and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
