Locks

History of Locks:

Locks may be entirely mechanical, or electromechanical. They may be operated by turning some form of removable key, by keying or dialing in a combination that directly or via electromechanical means, with some form of magnetic or other card reader, or by moving a part on a safety intended to prevent accidental operation rather than to prevent unauthorized access.

The warded one is the earliest type the only relative is present in now days prisons.

The pin tumbler lock is the most widespread  in the western world. Pin tumbler have been around in some form since 2000 BCE. The Egyptian form of this was large, heavy, and made of wood, with pins made of metal, usually bronze, but sometimes iron. This design in its modern form was first patented in 1805 in England. The patent holder was an American named A. O. Stansbury. In the middle of the 19th century, the American locksmiths Linus Yale Sr. and his son, Linus Yale Jr., refined the design into the form recognizable today. These early versions of the pin-tumbler locks were expensive to produce, and did not become widely available until mass production became feasible.

The first patent for the wafer tumbler was issued in the United States in 1868 to P. S. Felter. The wafer system is relatively inexpensive to produce and is often used in automobiles and cabinetry. This type of lock is generally made of die-cast zinc alloy.

The disc tumbler  or Abloy  was invented in 1907, and is widespread in Finland. The mechanism contains no springs and is durable.

Lever tumbler  were invented in Europe in the 17th century. This is a popular lock type for safes and North American prisons today, as they are generally built of strong materials. They are also used as door locks in some countries. This is the type of mechanism that replaced the medieval warded mechanism in the 19th century. Robert Barron of England patented the double-acting lever in 1778. Jeremiah Chubb would follow with his own detector lock in 1818.
