An example (open and closed) of a typical gun safe. A gun safe is a safe designed for storing one or more firearms and/or ammunitions.Gun safes are primarily used to prevent access by unauthorized or unqualified persons (such as children), for burglary protection and, in more capable safes, to protect the contents from damage by flood, fire or other natural disasters.
Lockmasters, Inc. markets the QX3 Combi Autodialer (LKMCOMBI) that works on a variety of 3 and 4 Wheel combination safe locks. [ 8 ] Another computer-aided method uses tools similar to autodialers, which instead make measurements of the internal components of the lock then deduce the combination in a way similar to that of a human safe cracker.

In the 17th century, in northern Europe, iron safes were sometimes made in the shape of a barrel, with a padlock on top. [3] In 1835, English inventors Charles and Jeremiah Chubb in Wolverhampton, England, received a patent for a burglar-resisting safe and began a production of safes. [4] The Chubb brothers had produced locks since 1818.
The closest Allied counterpart to the 3.7 cm Flak series was the 40 mm Bofors L/60, which was designated the "4 cm Flak 28" in German service. The Bofors fired a larger shell of 900 g (32 oz), as opposed to around 650 g (23 oz), at a slightly higher muzzle velocity of around 880 m/s (2,900 ft/s) as opposed to just under 800 m/s (2,600 ft/s).
This wheel design that came to be called artillery wheels was extensively used with artillery. [4] For example, this type of wheel was used on the pictured Armstrong gun , used in Japan in 1868. A similar design was used for a gun carriage for the US Army 's 3.2-inch gun in 1881, with a wheel diameter of 57 inches (1,448 mm), based on testing ...
Design of a horse-drawn, 3.7 cm anti-tank gun (designated 3.7 cm Pak L/45) by Rheinmetall commenced in 1924 and the first guns were issued in 1928. [5] By the early 1930s, it was apparent that horse-drawn artillery was obsolescent, and the gun was modified for motorized transport by substituting magnesium-alloy wheels and pneumatic tires for the original spoked wooden wheels, allowing it to be ...
Since this door weighs 22.5 short tons (20.4 t) this system is capable of applying 7.5 short tons-force (67 kN) inward. Unlike safes , vaults are an integral part of the building within which they are built, using armored walls and a tightly fashioned door closed with a complex lock .
