Clockwork alarm clock is also called mechanical alarm clock, which refers to the alarm clock with mechanical clockwork as the power source. It was invented in Concord, New Hampshire, USA in 1787. So who invented the mechanical alarm clock?
There are two theories about the inventor of clockwork alarm clock. One is LeviHutchins. He made an alarm clock out of a wooden box, and the mechanical device inside will ring the alarm clock. However, the alarm clock he invented can only ring at 4 a.m. and can't set the time, so he didn't apply for a patent for the alarm clock or mass production. He thought that it was not a patent to let the alarm clock sound, but the difficult thing was to come up with the idea, not to implement it.
Another way of saying it is Eric-ShaShuWa, who was just a fresh college graduate at that time. At that time, a classmate complained that he was dizzy when he woke up in the morning, which affected his exam results. So Eric founded a sleep research company with several classmates. With the support of the business community and alumni, he invented the mechanical clockwork alarm clock in 1788.
in p>1847, the French inventor AntoineRedier first applied for a patent for the adjustable mechanical alarm clock.
in p>1876, SethE.Thomas applied for a patent for a small mechanical wind-up alarm clock, and then major watch manufacturers produced this small alarm clock one after another.
around p>189, people invented the electric alarm clock.
Second, how did people get up on time before the invention of the alarm clock
It is the wish of most people to wake up naturally. Many people think that the invention of the alarm clock caused people to get up early, but in fact, there were other ways to wake people up before the invention of the alarm clock, so how did you get up early before the invention of the alarm clock?
1. Cockcrow
Cockcrow was a popular wake-up method in ancient China. It was found that the rooster would crow after 4: 3 in the morning every day, so every household could be woken up by the cock crow in the morning by raising chickens.
2. Human flesh alarm clock
A human flesh alarm clock is a wake-up call. In ancient China, there was a watchman occupation, that is, people who often saw in TV dramas, shouting "Dry weather, beware of burning candles", and they would work overtime at night to tell people the time.
Coincidentally, there are jobs like this in Britain, but they are called "window knockers" in Britain, which are only for one family. They will knock on the customer's window with a stick or bamboo pole every morning until the customer wakes up, and the general salary is about a few pence a week.
3. Bell
In ancient China, there was a saying that the bell rang in the morning and the drum sounded at night. When people nearby heard the bell, they knew it was time to get up. There are also church bells in the west to remind people to get up.
In a word, even before the invention of the alarm clock, people needed to get up on time, not the ancient people could sleep until they woke up naturally.
