Life Before the Zipper
Before the zipper was invented, it was very difficult for the lower class to find clothing that fit them correctly. They would usually have to get it made just for them, and that was hard to do if they were not rich. Many women had to use buttons to make their clothing fit. Men had to wear belts. The invention of zippers made getting dressed much quicker and more convenient.
The Introduction of Zippers
The first person to have a model of the zipper was Elias Howe. He called his design An Automatic Continuous Clothing Closure. This design had many clasps that had to be put together manually. It was pulled shut by a string.
The Evolution of the Zipper
More than 40 years later, Whitcomb Judson designed his Clasp Locker or Unlocker for Shoes. This model had hooks. Then he patented a similar device that worked much better, but often came undone. In 1913, Sundback revised and introduced a new model, which had interlocking oval scoops that could be joined together tightly by a slider in one movement or swoop. Gideon Sundback enhanced the zipper with the Plako fastener. The zipper was much tighter, but come undone when the person wearing it bent over or changed position.
Positive Effects of the Zipper
The zipper saves you time. You can hold things better because buttons can break and velcro can come apart. A lot of zippers are made out of metal, so the mining industry profited. Zippers can be used as jewelry.
Negative Effects of the Zipper
Some negative things about the zipper are that they can easily come apart and often get stuck. As you can see, there are a lot of good things about the zipper and not a lot of bad things.
