    Wake up its 4 AM ....

    03:27 0




            The first mechanical alarm clock was invented by "Levi Hutchins" of Concord, New Hampshire, in 1787.  The bell on this alarm clock could ring only at 4 AM, in order to wake him up, for his job. 
            On October 24,1876, a new mechanical wind up alarm clock is invented that could be set for any time. It was patented by Seth E Thomas.
