Bramah Lock
The Bramah lock was created by Joseph Bramah in 1784. The lock employed the first known high-security design. History After attending some lectures on technical aspects of locks, Bramah designed a lock of his own, receiving a patent for it in 1784. In the same year he started the Bramah Locks company at 124 Piccadilly, London. The locks produced by his company were famed for their resistance to lock picking and tampering, and the company famously had a "challenge lock" displayed in the window of their London shop from 1790, mounted on a board containing the inscription: The challenge stood for over 67 years until, at the Great Exhibition of 1851, the American locksmith Alfred Charles Hobbs was able to open the lock and, following some argument about the circumstances under which he had opened it, was awarded the prize. Hobbs' attempt required about 51 hours, spread over 16 days. The Challenge Lock is in the Science Museum in London. An examination of the lock shows that it has ...

Joseph Bramah
Joseph Bramah (13 April 1748 – 9 December 1814), born Stainborough Lane Farm, Stainborough, in Barnsley, Yorkshire, was an English inventor and locksmith. He is best known for having improved the flush toilet and inventing the hydraulic press. Along with William Armstrong, 1st Baron Armstrong, he can be considered one of the two fathers of hydraulic engineering. Early life Joseph Bramah was the second son in the family of Joseph Bramma (note the different spelling of the surname), a farmer, and his wife, Mary Denton. He was educated at the local school in Silkstone and on leaving school he was apprenticed to a local carpenter. On completing his apprenticeship he moved to London, where he started work as a cabinet-maker. In 1783 he married Mary Lawton of Mapplewell, near Barnsley, and the couple set up home in London. They subsequently had a daughter and four sons. The couple lived first at 124 Piccadilly, but later moved to Eaton Street, Pimlico. Improved water closet In ...

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 ...

Lock Picking
Lock picking is the practice of unlocking a lock by manipulating the components of the lock device without the original key. Although lock-picking can be associated with criminal intent, it is an essential skill for the legitimate profession of locksmithing, and is also pursued by law-abiding citizens as a useful skill to learn, or simply as a hobby (locksport). In some countries, such as Japan, lock-picking tools are illegal for most people to possess, but in many others, they are available and legal to own as long as there is no intent to use them for criminal purposes. History Locks by definition secure or fasten something with the intention that access is possible only with the matching key. Despite this, criminal lock picking likely started with the first locks. Famed locksmith Alfred Charles Hobbs said in the mid-1800s: Professional and recreational lock picking also has a long history. King Louis XVI of France (1754–1793) was a keen designer, picker, and man ...

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 ...

Crystal Palace From The Northeast From Dickinson's Comprehensive Pictures Of The Great Exhibition Of 1851
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. The word ''crystal'' derives from the Ancient Greek word (), meaning both "ice" and "rock crystal", from (), "icy cold, frost". Examples of large crystals include snowflakes, diamonds, and table salt. Most inorganic solids are not crystals but polycrystals, i.e. many microscopic crystals fused together into a single solid. Polycrystals include most metals, rocks, ceramics, and ice. A third category of ...

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 ...

Wafer Tumbler Lock
A wafer tumbler lock is a type of lock that uses a set of flat wafers to prevent the lock from opening unless the correct key is inserted. This type of lock is similar to the pin tumbler lock and works on a similar principle. However, unlike the pin tumbler lock, where each pin consists of two or more pieces, each wafer in the lock is a single piece. The wafer tumbler lock is often incorrectly referred to as a disc tumbler lock, which uses an entirely different mechanism. Early development The earliest record of the wafer tumbler lock in the United States is the patent in 1868 by Philo Felter. Manufactured in Cazenovia, New York, it used a flat double-bitted key. Felter's lock was patented only three years after Linus Yale, Jr. received a patent for his revolutionary pin tumbler mortise lock, considered to be the first pin tumbler lock of the modern era. That lock featured a flat steel key, referred to as a "feather key" because of the marked contrast with the heavy bit key ...

Tubular Pin Tumbler Lock
A tubular pin tumbler lock, also known as a circle pin tumbler lock, radial lock, or the trademark Ace lock popularized by manufacturer Chicago Lock Company since 1933, is a variety of pin tumbler lock in which a number of pins are arranged in a circular pattern, and the corresponding key is tubular or cylindrical in shape. Most locks use between six and eight pins, although some use as few as four or as many as ten. The devices have been widely used on vending machines, elevators, public computers, and bicycle locks. Design The design of a tubular lock is similar to the pin tumbler lock, in that there are several ''stacks'' of pins. The key is a cylinder shape with notches cut around the outer or (rarely) inner edge. Each of these notches depresses a single pin inside the lock to a specific height allowing the ''lock cylinder'' to turn freely. Uses Tubular locks are commonly seen on bicycle locks (such as the Kryptonite lock), Kensington computer locks, elevators, and a var ...
