| A common type of pin tumbler lock, of the euro cylinder type By Willh26 |
Locks in varying configurations have been employed by mankind since a large stone was first rolled in front of a cave entrance to assure privacy and control over entry.
The ancient Egyptians used intricate locks 4,000 years ago. The wooden contraption included a key that lifted pins, allowing a latch bar to slide free.
The pin-tumbler lock or yale lock was invented on June 13, 1844 by lock shop owner Linus Yale Sr, whose name still adorns billions of keys. Yale drew his inspiration from the Egyptian pin-and-bolt locks which were made of wood.
In 1850 his son, Linus Yale, Jr. joined him at the lock shop and began working on improving his father’s pin tumbler lock. Linus Yale, Jr.'s June 27, 1865 patent for a pin-tumbler lock and key was a drastic improvement over previous models, and is the basis for pin-tumbler locks since.
