Here at Airedale Springs, we are passionate about the range of springs that we stock. You will most likely be familiar with compression springs and extension springs and torsion springs because these are the most popular spring types. However, these springs are all extremely different and have many different uses and different jobs. In this article we will look into these springs in further detail and discuss the uses they are most known for.   

Extension Spring

These springs are tightly wound, with both ends of the spring having either hooks or loops to be used as an attachment. The most famous example of an extension spring use is in a trampoline. The trampoline uses extensions springs in order to create the bouncing effect. When someone jumps the extension springs are pulled apart and force is applied. As a consequence of this, the spring tries to go back to its original length, creating the inertia for a person on the trampoline to go into the air. The first modern trampoline is believed to have been made in 1936 by George Nissen and Larry Griswold, and is still widely used today. In addition to trampolines, extension springs are used on push and pull levers, rocking horses and screen doors. 

Compression Springs

Compression springs can be formed into many shapes including cylindrical, conical, barrel and hourglass; so it isn’t a surprise that they are considered to be the most popular springs. They are used in many products, including mattresses and mobile phones, but they are perhaps most well known for being the springs in pogo sticks. On a pogo stick, when the spring is at full compression, the person gets lifted by the recoil. The pogo stick was invented in 1891 by George H. Herrington, and it became extremely popular as a toy and exercise equipment in the late 1970s.  

Torsion Springs

A torsion spring is a spring that works by torsion (or twisting). These springs are ideal when there is a requirement for angular movement with the legs of the spring attached to other components. The design of a torsion spring is optimised to maintain maximum rotational pressure between two surfaces. Uses for the torsion spring include hinges and lever return applications, and also counter balancing the weight of garage doors. Additionally, they are well known for being used in mousetraps, with the first spring loaded mouse trap being invented by William C. Hooker of Abingdon. The mousetrap had a spring-loaded bar and a trip to release it. Although the mousetrap has evolved significantly, it has always been seen as an extremely important invention.
