Description
I have created a series of four versions of a very interesting lock. All four have various digital effects added for a rustic look. These would look wonderful on any wall of your home or workplace or as any of the great products sold on this site...........................WIKIPEDIA - Padlocks are portable locks with a shackle that may be passed through an opening (such as a chain link, or hasp staple) to prevent use, theft, vandalism or harm.
HISTORY - There are padlocks dating to the Roman Era, 500 BC – 300 AD.[They were known in early times by merchants traveling the ancient trade routes to Asia, including China.
Padlocks have been used in Europe since the middle La Tène period, subsequently spreading to the Roman world and the Przeworsk and Chernyakhov cultures. Roman padlocks had a long bent rod attached to the case, and a shorter piece which could be inserted into the case. Przeworsk and Chernyakhov padlocks had a sleeve attached to the case, and a long bent rod which could be inserted into the case and the sleeve.
Padlocks have been used in China since the late Eastern Han Dynasty (25–220 AD). According to Hong-Sen Yan, director of the National Science and Technology Museum, early Chinese padlocks were mainly "key-operated locks with splitting springs, and partially keyless letter combination locks".[6] Padlocks were made from bronze, brass, silver, and other materials. The use of bronze was more prevalent for the early Chinese padlocks.
Padlocks with spring tine mechanisms have been found in York, England, at the Jorvik Viking settlement, dated 850 AD (MUCH MORE HISTORY ON PADLOCKS FOUND ON WIKIPEDIA)
COMPONENTS - A padlock is composed of a body, shackle, and locking mechanism. The typical shackle is a "U" shaped loop of metal (round or square in cross-section) that encompasses what is being secured by the padlock (e.g., chain link or hasp). Generally, most padlock shackles either swing away (typical of older padlocks) or slide out of the padlock body when in the unlocked position. Less common designs include a straight, circular, or flexible (cable) shackle. Some shackles split apart and come together to lock and unlock.
There are two basic types of padlock locking mechanisms: integrated & modular. Integrated locking mechanisms directly engage the padlock's shackle with the tumblers. Examples of integrated locking mechanisms are rotating disks (found in "Scandinavian" style padlocks where a disk rotated by the key enters a notch cut into the shackle to block it from moving) or lever tumblers (where a portion of the bolt that secures the shackle enters the tumblers when the correct key is turned in the lock). Padlocks with integrated locking mechanisms are characterized by a design that does not allow disassembly of the padlock. They are usually older than padlocks with modular mechanisms and often require the use of a key to lock.
The more modern modular locking mechanisms, however, do not directly employ the tumblers to lock the shackle. Instead, they have a plug within the "cylinder" that, with the correct key, turns and allows a mechanism, referred to as a "locking dog" (such as the ball bearings found in American Lock Company padlocks) to retract from notches cut into the shackle. Padlocks with modular locking mechanisms can often be taken apart to change the tumblers or to service the lock. Modular locking mechanism cylinders frequently employ pin, wafer, and disc tumblers. Padlocks with modular mechanisms are usually automatic, or self-locking (that is, the key is not required to lock the padlock) (SEE MANY MORE TYPES OF PADLOCKS ON WIKIPEDIA)
