Claims
- 1. An alarm clock mechanism comprising:
- a. a timing mechanism;
- b. a supporting structure;
- c. an audible alarm vibrator mounted on said supporting structure for operation by said timing mechanism;
- d. a switch mounted on said supporting structure for operation by said timing mechanism;
- e. an alarm vibrator control lever mounted on said supporting structure and movable into engagement with said audible alarm vibrator for shutting off the alarm;
- f. a switch control lever mounted on said supporting structure;
- g. a manually operable selector cam mounted on said supporting structure and movable into engagement with said alarm vibrator control lever and said switch control lever for selectively controlling operation of said audible alarm vibrator and said switch, said selector cam including an integrally formed longitudinally variable cam surface movable into engagement with said switch control lever for moving said switch control lever for holding the switch in an open position and said selector cam including a second integrally formed radially variable cam surface movable into engagement with said alarm vibrator control lever for holding the audible alarm vibrator in an off position, said selector cam being movable to any one of a plurality of positions for controlling the operation of said audible alarm vibrator and said switch, said selector cam member being movable into one position wherein its integrally formed cam surfaces for controlling operation of the alarm vibrator control lever and the switch control lever holds both of these levers in an off position to prevent actuation of the audible alarm vibrator and to hold the switch control lever in an off position to prevent actuation of the switch, said selector cam being rotatable to another position wherein its integrally formed cam surface which is movable into engagement with the switch control lever is removed from the switch control lever to enable the switch to be automatically operated by the timing mechanism at an alarm time but wherein the integrally formed cam which is movable into engagement with the alarm control lever is retained in engagement with the alarm control lever for preventing automatic operation of the alarm vibrator by the timing mechanism at the alarm time.
- 2. An alarmm clock timer mechanism as defined in claim 1 wherein the longitudinally variable cam for controlling said switch control lever is integrally formed on said selector cam for moving the switch control lever rearwardly to prevent operation of the said switch and wherein the radially variable cam which is integrally formed on said selector cam for operating the alarm control lever is positioned for engagement with said alarm control lever to move said alarm control lever toward one side of the timer to prevent actuation of said audible alarm vibrator.
- 3. An alarm clock mechanism as defined in claim 1 wherein said alarm control lever is formed as an elongated lever having a central portion and two end portions and said alarm control mechanism also includes:
- a. spring means connected to said elongated alarm control lever for urging the lever to a first alarm position;
- b. a latch integrally formed on said alarm control lever for holding said alarm control lever in the other alarm position;
- c. said alarm control lever being mounted for longitudinal movement to move said alarm vibrator 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;
- d. 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; and
- e. a second cam means driven by said timing mechanism in selective engagement with the central portion of said alarm control lever for permitting said alarm control lever to be tilted into engagement with said first cam means a short time prior to said preset time.
- 4. An alarm clock switch timer mechanism comprising:
- a. a timing mechanism;
- b. a supporting structure;
- c. an audible alarm vibrator mounted on said supporting structure for operation by said timing mechanism;
- d. a switch mounted on said supporting structure for operation by said timing mechanism;
- e. an alarm vibrator control lever mounted on said supporting structure and movable into engagement with said audible alarm vibrator for shutting off the alarm;
- f. a switch control lever mounted on said supporting structure;
- g. a first cam means driven by said timing mechanism in selective engagement with said alarm vibrator control lever for moving said alarm vibrator control lever to permit the vibrator to sound at a predetermined alarm vibrator time;
- h. a second cam means driven by said timing mechanism in selective engagement with the alarm vibrator control lever for permitting the alarm vibrator control lever to be moved into engagement with said first cam means a short time prior to said predetermined alarm vibrator time, said second cam means being in engagement with said switch control lever for moving said switch to a closed position when said second cam means moves the vibrator control lever into engagement with the first cam means to thereby close the switch at the commencement of the actuating movement of the alarm vibrator control lever by said first cam means; and
- i. a manually operable selector cam positioned adjacent to said vibrator control lever and said switch control lever for actuating the switch control lever and the alarm control lever to shut off the alarm and open the switch, for actuating the vibrator control and switch control levers to be closed at some predetermined time and to permit the vibrator to sound a short predetermined time thereafter, and for actuating the vibrator control and switch control levers to permit the switch to be closed at some predetermined time and to prevent the vibrator from sounding.
- 5. An alarm clock switch timer mechanism as defined in claim 4 wherein the manually operable selector cam includes a forwardly extending cam surface for moving said vibrator control lever radially away from the axis of said selector cam to shut off the audible alarm vibrator, and said selector cam includes an arcuate cam surface for moving the switch control lever rearwardly to open the switch.
