The 1882 "Device For Waking Persons From Sleep" Patent
And you probably think your alarm clock is annoying. The idea behind this 1882 patent for a "device for waking persons from sleep" actually drops things on your sleeping head. A spindle inside the clock released a hook, attached to which was a string that held up 60 small pieces of wood assembled in a block. The sleeper would be awoken by this falling wooden block.
