THE HISTORY OF SPRING
There are two types of springs- non-coiled spring and 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
In the 18th century
In the 1493
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.
In the 18th century the French put a plate, onto a carriage. This metal plate is considered a leaf spring, it
was the first ever leaf spring used on a vehicle.
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.
In the 1763
In the 1857
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.
