An alarm clock construction having a frame carrying time mechanism and a timer motor for driving the time mechanism, the time mechanism including an alarm setting member for selecting a predetermined time the clock construction is to sound an alarm. A reed member is pivotally carried by the frame to pivot on an intermediate pivot point thereon and is adapted to pivot to an alarm producing position when the time mechanism reaches the predetermined time. An on-off alarm member has a biasing part for acting on the reed member on one side of the pivot point to tend to bias the reed member to the alarm producing position when the on-off alarm member is in the "on" position thereof and for acting on the reed member on the other side of the pivot point to tend to bias the reed member out of the alarm producing position when the on-off alarm member is in the "off" position thereof. An actuator member is movably carried by the frame and is movable to a position to temporarily hold the reed member out of the alarm producing position thereof even though the on-off alarm member is in the "on" position thereof, the actuator member movably carrying a pinion-like member that moves relative to the actuator member and cause the actuator member to move out of its alarm stopping position to again sound the alarm after the lapse of a certain time period.
In an alarm clock construction having frame means carrying time means and a timer motor for driving said time means, said time means including an alarm setting means for selecting a predetermined time said clock construction is to sound an alarm, said alarm sound being adapted to be created by a reed member pivotally carried by said frame means and being controlled by an on-off alarm member movably carried by said frame means, the improvement wherein said reed member has an intermediate pivot point that pivots on said frame means to permit said reed member to pivot to an alarm producing position when said time means reaches said predetermined time, said on-off alarm member having biasing means for acting on said reed member on one side of said intermediate pivot point to tend to bias said reed member to said alarm producing position when said on-off alarm member is in the "on" position thereof and for acting on said reed member on the other side of said intermediate pivot point to tend to bias said reed member out of said alarm producing position when said on-off alarm member is in the "off" position thereof, said biasing means of said on-off alarm member comprising a leaf spring member engageable with and slidable relative to said reed member, said reed member having a slot therein that extends from one side of said pivot to the other side of said pivot point, said leaf spring member having a tang disposed in said slot to guide movement of said on-off alarm member relative to said reed member.
In an alarm clock construction having frame means carrying time means and a timer motor for driving said time means, said time means including an alarm setting means for selecting a predetermined time said clock construction is to sound an alarm, said alarm sound being adapted to be created by a reed member pivotally carried by said frame means and being controlled by an on-off alarm member movably carried by said frame means, the improvement wherein said reed member has an intermediate pivot point that pivots on said frame means to permit said reed member to pivot to an alarm producing position when said time means reaches said predetermined time, said on-off alarm member having biasing means for acting on said reed member on one side of said intermediate pivot point to tend to bias said reed member to said alarm producing position when said on-off alarm member is in the "on" position thereof and for acting on said reed member on the other side of said intermediate pivot point to tend to bias said reed member out of said alarm producing position when said on-off alarm member is in the "off" position thereof, said reed member having opposed ends, one of said ends of said reed member being movable to closely adjacent said motor to cooperate therewith and provide said alarm sound when said reed member is pivoted to said alarm producing position thereof, the other end of said reed member being operatively associated with said alarm setting means to be operated thereby.
In an alarm clock construction having frame means carrying time means and a timer motor for driving said time means, said time means including an alarm setting means for selecting a predetermined time said clock construction is to sound an alarm, said alarm sound being adapted to be created by a reed member pivotally carried by said frame means and being controlled by an on-off alarm member movably carried by said frame means, the improvement wherein said reed member has an intermediate pivot point that pivots on said frame means to permit said reed member to pivot to an alarm producing position when said time means reaches said predetermined time, said on-off alarm member having biasing means for acting on said reed member on one side of said intermediate pivot point to tend to bias said reed member to said alarm producing position when said on-off alarm member is in the "on" position thereof and for acting on said reed member on the other side of said intermediate pivot point to tend to bias said reed member out of said alarm producing position when said on-off alarm member is in the "off" position thereof, and actuator means carried by said frame means for temporarily moving said reed member out of said alarm producing position thereof for a certain time period.
