Wafer Tumbler Lock
A wafer tumbler lock is a type of Lock (security device), 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 a patent from 1868 by Philo Felter. Manufactured in Cazenovia, New York, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lock (security Device)
A lock is a mechanics, mechanical or Electronics, electronic fastening device that is released by a physical object (such as a key, Keycard lock, keycard, fingerprint, Radio-frequency identification, 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 (key), bit'' or ''blade'', which slides into the keyhole, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pin Tumbler Lock
The pin tumbler lock, also known as the Yale lock after the inventor of the modern version, is a lock mechanism that uses pins of varying lengths to prevent the lock from opening without the correct key. Pin tumblers are most commonly employed in cylinder locks, but may also be found in tubular pin tumbler locks (also known as radial locks or ace locks). History The first known example of a tumbler lock was found in the ruins of the Palace of Khorsabad built by king Sargon II (721–705 BC.) in Iraq.James, Peter, and I. J. Thorpe. Ancient Inventions. New York: Ballantine, 1994. Basic principles of the pin tumbler lock may date as far back as 2000 BC in Egypt; the lock consisted of a wooden post affixed to the door and a horizontal bolt that slid into the post. The bolt had vertical openings into which a set of pins fitted. These could be lifted, using a key, to a sufficient height to allow the bolt to move and unlock the door. This wooden lock was one of Egy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Tumbler Lock
A disc tumbler or disc detainer lock is a lock and key, lock composed of slotted rotating detainer discs. The lock was invented by Finnish founder of Abloy, Emil Henriksson (1886–1959) in 1907 and first manufactured under the Abloy brand in 1918. Design Disc tumbler locks are composed of slotted rotating detainer discs. A specially cut key rotates these discs like the tumblers of a safe to align the slots, allowing the sidebar to drop into the slots, thus opening the lock. Unlike a wafer tumbler lock or a pin tumbler lock, this mechanism does not use springs. Because they do not contain springs, they are better suited for areas with harsh conditions and are often used at outdoor locations like railroad and public utility installations. The original Abloy Classic design consists of a notched semi-cylindrical key, and a lock with detainer discs with holes ranging from a semicircle (180°) to a 3/4 circle (270°). The key is inserted and rotated 90°. Notches, machined to an a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contour Gauge
A profile gauge or contour gauge is a tool for recording the cross-sectional shape of a surface. Contour gauges consist of a set of steel or plastic pins that are set tightly against one another in a frame which keeps them in the same plane and parallel while allowing them to move independently, perpendicularly to the frame. When pressed against an object, the pins conform to the object. The gauge can then be used to draw the profile or to copy it on to another surface. Applications Profile gauges are used widely in metalworking and woodworking. In architectural conservation, they are used to document the profiles of decorative moldings.Neal Vogel, Christopher Jenks, "Documentation Projects, Part 2: Measured Drawings", ''Common Bond'' (New York Landmarks Conservancy) Winter, 199full text In archaeological illustration Archaeological illustration is a form of technical illustration that records material derived from an archaeological context graphically.Barker 1977 Overview A ...

Locksmith
Locksmithing is the work of creating and bypassing locks. Locksmithing is a traditional trade and in many countries requires completion of an apprenticeship. The level of formal education legally required varies by country, ranging from no formal education to a training certificate awarded by an employer, or a full diploma from an engineering college, along with time spent as an apprentice. Terminology A lock is a mechanism that secures buildings, rooms, cabinets, objects, or other storage facilities. A "smith" is a metalworker who shapes metal pieces, often using a forge or mould, into useful objects or to be part of a more complex structure. Thus locksmithing, as its name implies, is the assembly and designing of locks and their respective keys by hand. Most locksmiths use both automatic and manual cutting tools to mold keys, with many of these tools being powered by batteries or mains electricity. Work Locks have been constructed for over 2500 years, initially out of wood and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
