Abstract
An add-on device for automatically adjusting the setting of a control mechanism, such as, a thermostat, which includes a separate, independent timer which is mounted adjacent the existing control mechanism and controls the same by means of a mechanically driven member which engages the manual adjuster of the control mechanism; the device further including a suitable coupler for coupling the driven member to the timer for moving the driven member at selected times to change the position of the adjuster.
Claims48
A device for automatically adjusting the setting of a control mechanism having an externally accessible adjuster for raising and lowering the setting of the control mechanism, said device comprising:
- mechanically driven means for engaging and moving the adjuster of the control mechanism, drive means for driving said mechanically driven means, electrical circuit means for controlling the operation of said drive means including multiple switch means for opening and closing said electrical circuit means, timing means for controlling one of said switch means for periodically closing said electrical circuit means at predetermined times for a limited time interval to activate said drive means, and switch control means for controlling another of said switch means movable simultaneously with said mechanically driven means for opening said electrical circuit means after a predetermined amount of adjusting movement.
An automatic adjusting device adapted for mounting adjacent a pre-existing thermostat of the type which includes an externally accessible adjuster for changing the position of the adjuster to change the temperature setting of the thermostat, said device comprising:
- mechanically driven means separably connectable to the adjuster of the thermostat,
- drive means for driving said mechanically driven means alternately in first and second directions for changing the position of the adjuster to raise and lower the temperature setting of the thermostat,
- electrical circuit means for controlling the operation of said drive means including switch means for opening and closing electrical circuit means, and
- timing means cooperating with said switch means for periodically closing said electrical circuit means at predetermined times to activate said drive means.
