There are two types of main springs a non-coiled spring and a coiled spring. The non-coiled spring has been around forever. A great example of a non-coiled spring is a bow and arrow. A bow and arrow has been around to help with food and protection. This is one of the earliest spring technologies. Anytime a string is tightened to create a bounce, that can be considered a “spring”.

In the 1300’s there was spring technology being used in chariots. Chariots had a complex spring and suspension system built in, that helped give them more miles.

Leaf Springs

In the 18th century the french put on a plate, onto a carriage. This metal plate is considered a leaf spring, it was the first ever leaf spring used on a vehicle.

The Pistol

In 1493, Leonardo Da Vinci built the first spring into a pistol. This spring was customized just for the pistol. It made it possible for the pistol to be shot off in a single hand. This spring was the beginning of revolutionizing the gun. Guns today use all sorts of spring technology to make guns work efficiently.

The First Coiled Spring

It wasn’t until 1763 when R. Tradwell invented the first ever coiled spring.  It was a Brittish patent, number 792.  It was considered a step up from the leaf spring. The leaf spring had to be lubricated often and was quite squeaking. The best was that the spring didn’t have to be spread apart.

The word coil meant to wind cylindrically or spirally. In the year 1857 the first ever steel  coil spring was invented. It was used for chair seats.

Ever since the inventions of these coil springs, springs have been used in everything from shoes to trampolines. Springs help make the car industry what it is today. Springs are used in every type of machinery and they really do help make the world go around.
