Vending machines are everywhere, always displaying snacks, drinks, and other items. You put your coins in and something good comes out! You can see them almost everywhere, selling everything from newspapers to food, and they haven’t died out at all. Like many other modern marvels, they were created in ancient Rome, and they dispensed holy water.
A citizen would put a coin inside of the machine which would fall on a pan. That pan would control a lever that opened a valve and dispensed the holy water. The pan would continue being weighed down by the coin until the coin fell off, the pan snapped back up, and the valve closed.
England was the next great nation to focus on vending machines, using them to distribute stamps, postcards, and tobacco. Soon a German businessman named Stollwerck used his own vending machines to distribute food, chocolate, soap, and cigars. The first vending machine in the U.S was built by the Thomas Adams Gum Company, and the company’s machines sold gum.
Most vending machines work on the same principle as the early machine. A coin or other payment device is put in, and that triggers some sort of reaction that releases the desired product, for example, most snack machine los angeles items are held in place by coils. When someone wants a bag of chips, they insert that information and the coil that is holding the chips rotates and falls into the area where it can be collected.
Other times, such as with a newspaper box, the insertion of the coin is what unlocks it. Then you can take a paper and once the door is closed, it locks again. Vending machines work on the principle of cause and effect, and it’s really interesting to see how putting in one coin releases the item you want.
