The first mechanical alarm clock was invented by Levi Hutchins, of New Hampshire, in the United States, in 1787. This device he made only for himself however, and it only rang at 4 AM, in order to wake him for his job. The French inventor Antoine Redier was the first to patent an adjustable mechanical alarm clock, in 1847. It was called the Jingle Clock, or it may have been used just to wake somebody up. Some people use the alarm clock just to see what time it is, and some people may just use the alarm clock for show, or just to see what time it is, or to wake you up, and to tell what time it is.
