Basic knowledge of safes, do you know this?

The safe was thought to have originated in Europe. The safe at the time was only a solid wooden box tied with iron rings. The sample of this old wooden box was still kept at the Cathedral of Chichester in England. It is 9 feet long, 2 feet high and 2 feet deep. It is made of 2 inches thick wood and has a history of about 1,000 years. This is probably the oldest safe kept so far. In medieval European paintings, occasionally there was a wooden cabinet full of gold and silver jewellery and metal edging. This was the prototype of a safe.

Until about the beginning of the 19th century about 200 years ago, with the growth of social wealth, the safe market had a realistic market demand. European manufacturers specialized in making locks began to move to the safe industry. In 1818, the Chubb lock and safe manufacturing factory was established in London. . In 1825, France's FICHE-BAUCHE company was established. These manufacturers then began to make safes. In the late 18th century, Carron Co. of Scotland and Coalbrookdale of England began manufacturing cast-iron boxes and bookcases. This is the origin of metal safes, but basically the splicing technique or the whole casting of woodware is used. The appearance and craftsmanship are similar to the furniture at the time, and the precision of locks is very low.
The main users of early commercialized safes are banks, insurance companies, government archives, and commercial institutions. The safe is made of cast iron and is completed by riveting and splicing technology. Cast iron ribs (doors or separate pieces) are added to the box and door to increase the strength. The appearance and the lock of the safe seem to be strong. The lock and the mechanism are relatively simple. , So the safes at the time were just some seemingly solid iron boxes. The thickness of the door was generally 1/2 inch (12 mm).
In the beginning, safes were not fire-proof, and fire damage made people aware of the importance of fire prevention. In the early 19th century, there was a fire safe, made of wood soaked with alkali solution; around 1827, the British Thomas Milner (Milner used to be the largest insurance manufacturer in the United Kingdom) began to manufacture an inner and outer layer made of tin plate. And iron plate production, filled with hardwood, sawdust and alum mixture of non-thermal conductive material between the inner and outer layers, this is considered to be the earliest fire safe, but only a fire protection function, do not have anti-theft effect. It can be said that the development of anti-theft safes and fire safes is almost at the same time.
From the end of the eighteenth century to the end of the nineteenth century, the United Kingdom has mushroomed as the following well-known safe manufacturers: In 1795, E.Tann & Sons In 1818, the Chubb lock and safe manufacturer was established in London, but at the time only the locks were produced, but the Tann Dai Manufacturing boxes and doors. In 1836, Chubb established his own safe manufacturing facility in Smithfield Cowcross, London.

Among them, Chubb registered patents on anti-theft safes in 1833, and then quickly developed into an industry champion. He has been dominating the safe industry for nearly 100 years. In this century, most of the world-famous companies in the financial sector use them. Chubb's products, even in the oldest bank buildings in China's earliest open coastal cities like Hong Kong, Shanghai, and Guangzhou, can still see Chubb's nearly 100-year-old safe.
The copper safes salvaged from the Titanic wreck are over 200 years old. It now appears that it is just a copper box with a buckle and a lock.
200 years ago iron safe. The exterior looks like an ordinary two-door iron cabinet. The door hinge is similar to that of a wooden device, and its production technology is excellent.
The early safe, which has a history of about 180 years, has a butterfly hinge hinged with rivets. The appearance is strong. The safe manufactured by American Bank Lock Co., Ltd. in 1841 had only a square type lock 1840 that was directly operated by a key. Wilder Patented Fire Dragon (Salamander)
The development of fire safe safes in the United States was slightly later than in Europe, but in terms of fire safes, the development rate was faster than the latter. Before Thomas Milner of the United Kingdom began manufacturing fire safes, Jesse Delano of the United States applied for the world's first patent for improved technology for fire safes in 1826. In 1825, Jesse Delano began producing iron boxes in New York, USA. He was considered to be the earliest modern safe manufacturer in the United States. Following Jesse Delano, CJ Gayler began manufacturing safes in the United States. In 1833 he filed a patent for a "double chamber fire box," but it turned out that CJ Gayler's products could not effectively withstand heat in a fire. John Scott applied for a patent for asbestos in a fireproof box in 1833.
In the early 1930s, American F. Daniel Fitzgerald discovered the method of using the now-familiar Paris plaster as insulation material to make a more reliable fireproof safe. Enos Wilder later obtained this patent and produced a lot of naming. Fire safe for Salamander. In the Great Fire of New York in 1845, Wilder's patented Salamander safe protected a large number of properties and technology and products were verified. Although Spear discovered an alternative in 1852, the use of Wilder patent safes became popular in the 1940s and 1850s.
In the early 19th century, safes were wooden boxes reinforced with iron sheets and padlocks. The contents contained in them were “easy money” for thieves. They could easily damage locks, smash or take away safes. In order to store higher-value items, the anti-theft performance of safes continues to increase; thieves are constantly "drilling" on technology. This started the race between safe makers and the "safe robbers." This "race" has effectively promoted the development of the safe industry, and it also inspires people to continue their efforts in the design and craft of safes until today.
After the appearance of the fire safe, at that time, manufacturers in Europe and the United States paid more attention to the fire performance and ignored the anti-theft performance. However, a theft case caused a historic change in the anti-theft performance of the safe.
Earlier in 1865, the Cornhill Robery in Cornwall, London, caused a loss of approximately £850,000. This case had a profound effect on the safe design of modern safes. This led to the production of 36 patented technologies concerning safe cabinet structures, doors, lock mechanisms, and multi-directional interlock bolts. Some patented technologies are still in use today.
The lock mechanism of the early safe was directly operated by the key instead of the handle, and the safety performance was affected. In 1866, Samuel Whitfield filed a patent for a gear transmission he invented. This technology used gear transmission to extend the bolt behind the door frame of the box. At the same time, James Felton Elwell designed the first handle-operated four-way locking bolt linkage mechanism. Samuel Whitfield applied the technique of James Felton Elwell's own technology and was called the Sicker patent safe at that time. The Sicker patent safe opened the door to a new generation of technology that freed the key from direct manipulation of the locking bolts and greatly improved safety.
Sicker patent safes around 1867 can be seen independently of locks, handle-operated interlocking four-way locking mechanism and circular locking bolts, which may be the earliest safe using circular locking bolts.
1890s English Ratner Level 3 Safe Door Panels and Mechanisms. Uses many new technologies that emerged at the time. The safe has a fixed cage design and four 3/8-inch (10mm) T-plates riveted to a 1/2-inch (12mm) door panel to form a mechanism box, plus a 3/8-inch thick body, The bolt mounting plate has a total thickness of 7/8 in. (23 mm), a 1/2 x 1/2 in. deadbolt on the hinged end of the door, and the back cover of the mechanism contains a fireproof layer and is screwed onto the wall. All the bolts can be found to be square.
