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.

Claims4

Dependent claims

A repeat alarm clock mechanism comprising:

a. a timing mechanism;
b. a supporting structure;
c. an alarm vibrator member for sounding an alarm connected to said supporting structure;
d. a vibrator shutoff lever having an alarm on position out of engagement with said vibrator member and an alarm off position in engagement with said vibrator member;
e. a pivot tab integrally formed with said vibrator shutoff lever for mounting said vibrator shutoff lever for pivotal and longitudinal movement on said supporting structure;
f. spring means connected to said vibrator shutoff lever for urging said lever to an alarm on position;
g. a latch integrally formed on said vibrator shutoff lever for holding the vibrator shutoff lever in the alarm off position;
h. means driven by the timing mechanism in selective engagement with a portion of the vibrator shutoff lever for moving the lever to disengage said latch to permit the vibrator shutoff lever to move longitudinally under the force of said spring means to permit the alarm to sound;
and
i. a repeat alarm lever mounted on said supporting structure, said repeat alarm lever being manually movable into engagement with said pivot tab for moving the vibrator shutoff lever against the force of said spring means to reset said latch to thereby hold the alarm shutoff lever in the alarm off position for a predetermined short time interval.

An alarm clock mechanism comprising:

a. a timing mechanism;
b. a supporting structure;
c. a member for sounding an alarm connected to said supporting structure and movable to an alarm on and an alarm off position;
d. an elongated alarm control lever mounted on said supporting structure and movable into engagement with said member for shutting off the alarm, said elongated alarm control lever having a central portion and two end portions;
e. spring means connected to said elongated alarm control lever for urging said lever to a first alarm position;
f. a latch integrally formed on said alarm control lever for holding said alarm control lever in the other alarm position;
g. said alarm control lever being mounted for longitudinal movement to move said member to an alarm sounding position or an alarm off position, said alarm control lever being mounted for tilting movement, and said alarm control lever being mounted for transverse movement;
h. a first cam means driven by said timing mechanism in selective engagement with an end portion of said alarm control lever for moving said lever transversely at a preset time to disengage said latch to permit said elongated alarm control lever to move longitudinally under the force of said spring means to move said member to said first alarm position at a preset time;
i. a second cam means driven by said timing mechanism in selective engagement with the central portion of said alarm control lever for tilting said alarm control lever into engagement with said first cam means a short time prior to said preset time;
and
j. a rearwardly extending pivot tab integrally formed with said elongated alarm control lever, said tab extending through a slot which is formed in a base plate of said supporting structure and said tab being positioned for engagement with a repeat alarm lever for moving the elongated alarm control lever longitudinally to reset the latch to thereby prevent the alarm from sounding for a short time interval.
