What is the timeline of wheelchairs?

During WW1, there was extreme scarcity in food. For this reason, only certain amounts of food and drink could be given to people, and this was very little. These allowances of food were known as rations.
To save cost on fuel, which was extremely expensive, food rations for each village and town were transported by wheeled carts instead of motorised vehicles. This is because the food never had to be transported far, as each town/village/area was given its own supply. Many people didn't have the things needed to build a cart, and so would find old broken and discarded chairs and upturned tables, and by salvaging the wheels of old prams and bicycles, and fasten these to the chairs. These were known as 'wheeley chairs' and were popular amongst locals.
However, when seriously injured soldiers needed to be exported or taken to hospital, transportation was needed. At this time Britain was low on fuel and so the prices went up and up, meaning no-one could afford it. Roads were also blocked, and access with any vehicle would be limited. People began to use their 'wheeley chairs' or ration carts, to transport injured soldiers to medical help waiting, in some cases, on the other side of town, where they could be treated safely.
These chairs became very popular and the public were praised for the ingenious idea which helped save lives. For this reason, after the war, hospitals began to make their own, paying manufacturing companies to bring the original design to a more suitable level, giving comfort and ease to the user. The name was slightly altered from 'wheeley chairs' to wheelchairs, and from then onwards, we have used them in hospitals, and even supermarkets stock them for customer use.
