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.

Karratti of Hawaii writes, “Have equipped my car with Devil-Dog and am creating a sensation.” Ernest Flom, No. Dakota, states, “The Police force praise it highly.” Richard Tacques, Canada, writes, “Have sold one for Police armored car and am getting letters from Chief of Police and Detective Departments.” What these men say is just an indication of what motorists everywhere are saying. No wonder our agents are making money hand over fist, both spare time and full time.

    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.
