Every year the U.S. receives tens of thousands of inventions. Of these only a few become popular and make a lot of money. There are thousands of inventions that nobody wants.
Here are some of those.
In 1879, somebody invented a new type of “fire escape”. This was a hat which had a parachute on top. You connected the hat with a strap under your chin. With this special hat you could jump from a building on fire and flew safely down. With it there was also a special pair of shoes, so the person landed safely.
There was a special alarm clock for people who had trouble in waking up in the morning. This clock had six pieces of wood that hung above your head. At the right time the pieces of wood dropped down on you when you were sleeping. They hit you but did not hurt you. Therefore, you woke up.
Another invention was the bicycle seat to stop a thief. This seat had needles in it. When the owner rode the bicycle, the needles were down But when the bicycle was not in use, the needles were up. So a thief who jumped on the bike got a nice surprise!
