YONGFA INTELLIGENT TECHNOLOGY SECURITY CO., LTD.
Safes originated in Europe, but in the area of safe fire protection, the United States has grown faster than Europe. Before the United Kingdom started manufacturing its fire safes, the United States had already applied for the first patent in the world to improve its technology for fire safes. In 1825, the United States Jesse Delano began producing iron boxes and was called the earliest safe manufacturer in the United States. After Jesse Delano, CJ Gayler also started manufacturing safes in the United States. In 1833 CJ Gayler filed a patent for a “double chamber fire box”, but in fact such a safe could not effectively resist heat in a fire. Later, they also applied for a patent for the use of asbestos in fireproof boxes. In the 1930s, the development of fire safes was in full swing. In 1845, a safe in a large fire in New York was verified and protected a lot of property.
