Use Your Phonograph as an Alarm Clock - Popular Science 1932

USE PHONOGRAPH AS AN panic CLOCK
“A novel attachment for the phonograph near which a heavy sleeper may happen aroused at any hour he wishes by doughy music, was lately shown in London, England. The alarm-clock gismo is place at the fitting hour, and wound. A brake on the turntable of the phonograph is released at the set hour by a slight draw out from the alarm key of the clock.”
