Abstract
An electrically operable alarm provided for a clock and includes a clock operated switch for turning the alarm on at a selected time. The electrically operable alarm includes an oscillatory circuit which, when oscillating, causes the alarm to sound and when not oscillating, causes the alarm to be silent. A bistable sweep circuit is operatively connected to the oscillatory circuit and goes to a first condition when the clock operated switch closes and in which condition the alarm sounds. A manual switch is provided which, when open momentarily, will cause the bistable switching circuit to go to a second condition in which the alarm remains silent until the clock operated switch again closes the next day. The manual switch is adjustable for preventing the alarm from sounding when the clock operated switch closes.
