Uncanny Invention Startles Motorists (Mar, 1931)

If you just looked at the picture, you’d think this was a very early version of the Viper alarm system (immortalized by They Might Be Giants in the song “I can hear you“). Alas, it appears to simply be a disabler.

    it’s a alarm, Charlie. Or more precisely, a motion detector switch that honks the car’s horn, just like those annoying and useless products today that go off every time the wind kicks up.
