I had no idea locks had been around for so long. Records show locks were found in Egypt as far back as 4,000 years ago. Mounted on the door post the lock was a long wooded bolt with a slot that had several holes. These holes were filled with wooded pegs that dropped into place with gravity and thus “locked”.
The Romans introduced the use of fixed obstructions in a lock, or wards, to prevent entry. You know the term “to ward off” well this is how it came to be. In 1784 Bramah locks were created and the use of sliders in a circular pattern were found to provide excellent security. Bramah is the oldest lock company in the world and continues to manufacture over 200 years later.
Of course with the invention of the lock came the ingenuity of the lock picker. Locksmiths rose to the challenge and invented keys with changeable bits along with alarm bells that went off when the bolt was turned.
In Colonial America the key hung outside of the door it was a simple length of string. Doors were latched on the inside with a pivoted wooded bar or bolt, one end dropping into a slot in the jamb. Attached was a piece of string that was threaded through a small hole to the outside. Pulling on the string raised the bolt and opened the door.
