Spring locks were invented in the mid-19th century, with notable advancements occurring around the 1850s. They were designed to improve security in locks by using a spring mechanism to engage and disengage the locking mechanism. The development of spring locks marked a significant evolution in locking technology, providing greater convenience and security compared to earlier locking systems.

About 4,000 years ago wooden locks and keys were invented.
Spring locks are a type of locking mechanism that utilizes a spring to secure a door or gate when closed. When the door is pushed shut, the spring engages with a latch or bolt, automatically locking it in place. These locks can often be opened from the inside without a key, making them convenient for quick exits. However, they may be less secure than other locking mechanisms, as they can sometimes be manipulated or bypassed easily.

The spring balance was invented by Richard Salter, a British balance maker, in the late 18th century. His invention revolutionized the way weight measurements were taken by utilizing the elasticity of a spring to measure force.
Locks were first invented around 4000 years ago in ancient Egypt. The earliest known locks were made of wood and consisted of a wooden bolt that slid into a slot to secure a door or gate. Over time, locks have evolved and become more sophisticated, with various types and mechanisms developed to enhance security.
