ABSTRACT:
An alarm vibrator control mechanism for a clock timer wherein an elongated lever extends along the lower portion of the timer for releasing an alarm vibrator at a preset time. The elongated lever is controlled by a selector shaft mechanism which is positioned at one side of the timer, a centrally located 12 hour alarm time gear and a disc cam which is connected to a units shaft at the other side of the timer. The 12 hour alarm time gear tilts the vibrator shutoff lever forwardly a few minutes before the alarm time and then the disc cam moves a right side portion of the elongated lever downwardly at the alarm time to release the elongated alarm shutoff lever from a notch which is formed in a base plate to sound the alarm. A repeat alarm lever cooperates with a tab of the elongated lever to automatically shut off the alarm for a short time interval.
