USE PHONOGRAPH AS AN ALARM CLOCK
A novel attachment for the phonograph by which a heavy sleeper may be aroused at any hour he wishes by soft music, was recently shown in London, England. The alarm-clock device is set at the desired hour, and wound. A brake on the turntable of the phonograph is released at the set hour by a slight pull from the alarm key of the clock.
