Boat-shaped locks, First half of the third century, released by jtautosecurity co uk

The clostraria ars , also known as the “art of the locksmith” was already an independent office in Roman and later period. Luxurious locks and padlocks boat shaped show that their manufacture had not merely functional. Its shape is usually round, although in some cases it is also rectangular and octagonal, and the casing is made ​​of iron, iron with bands of silver or bronze, or simply bronze.

The intended use for these locks were fork locks, padlocks for chains and shackles and toes. The realknow-how lies in the ingenious closing mechanism. The boat-shaped locks are divided according to their different locking mechanisms: in twistlocks with sliding latch, raised the key to turning the locking spring.Once he released the latch is pushed toward the bottom while still turning and the locking pin is released.To remove the key from the lock, you must first return to the starting position. The twist – lock mechanism with closing spring is simpler. When the key is turned 180 degrees, engage the teeth of the bit through the guard and push the closing spring back with the nose. This releases the latch. Thanks to the spring pressure, returns to its closed position automatically when released. If you have to close the lock, simply enter again the latch and lock it slams shut.

The 14 boat-shaped locks found in the tank Neupotz that may be some in the exhibition of the MARQ,the Treasury Barbarians are so far only by their quantity and condition. The two locking mechanisms described have been found from X – rays. All housings are made ​​of iron sheets. Along with unadorned copies are also others who have three decorative brass bands and the heads of the molded rivets.Compared with existing locks, these simple locks were not very strong. They should exercise more of a chilling effect, as the use of physical violence produced noise and could draw the attention of residents and neighbors.
