A food processor includes a base and a bowl with a removable lid. Food items are advanced into the bowl through a feed tube formed in the lid where they are cut by a cutting assembly driven by a motor. The cutting assembly is adjustable to vary the thickness of the cut food items. An adjustment assembly positioned in the base is operable to adjust the cutting thickness of the cutting assembly while the cutting assembly is driven by the motor.

The food processor of claim 3, further comprising: a drive shaft connected at a first end to the motor and at a second end to the cutting assembly to transmit a driving force from the motor to the cutting assembly, andwherein (i) the first sleeve includes a bearing rotatively supporting the drive shaft, and (ii) the drive shaft extends through an opening defined in the second sleeve, the opening being sized such that the drive shaft does not contact the second sleeve. 5. The food processor of claim 4, further comprising a first adaptor removeably coupled to the rotating disk, and a second adaptor secured to a lower end of the first adaptor, wherein the second sleeve includes a bearing rotatively supporting the second adaptor. 6. The food processor of claim 5, wherein the lower end of the first adaptor includes a first plurality of teeth, and the second adaptor includes a second plurality of teeth interdigitated with the first plurality of teeth to secure the second adaptor to the first adaptor. 7. The food processor of claim 1, wherein the adjustment assembly further comprises: a gear assembly positioned in the base and coupled to the second sleeve, the gear assembly being operable to rotate the second sleeve relative to the first sleeve, andwherein the user-operated control device is coupled to the gear assembly and is configured to operate the gear assembly such that the second sleeve is rotated relative to the first sleeve to move the cutting assembly between the plurality of cutting positions. 8. The food processor of claim 7, wherein the second sleeve has a groove defined therein, and the gear assembly comprises (i) a first gear including a first plurality of teeth defined on an outer surface and a spline extending from an inner surface, the spline being received in the groove of the second sleeve, and (ii) a second gear including a second plurality of teeth interdigitated with the first plurality of teeth, wherein the user-operated control device causes rotation of the second gear and the first gear. 9. The food processor of claim 8, wherein the user-operated control device includes a lever extending outwardly from the base and positionable between a plurality of adjustment positions relative to the base, the lever being coupled to the second gear such that movement of the lever between the plurality of adjustment positions device causes rotation of the second sleeve relative to the first sleeve to move the cutting assembly between the plurality of cutting positions. 10. The food processor of claim 9, further comprising a locking mechanism to inhibit movement of the lever. 11. The food processor of claim 10, wherein the locking mechanism comprises: a plurality of notches formed in the second gear, each notch corresponding to one of the plurality of adjustment positions,a pin positioned below the second gear, the pin being configured to be received in each of the plurality of notches, anda spring coupled to the pin, the spring biasing the pin into the notch corresponding to a present adjustment position of the lever to inhibit movement of the lever. 12. A food processor comprising: a base having a motor positioned therein,a removable bowl coupled to the base,a removable lid coupled to the bowl so as to define a processing chamber, the lid having a feed tube that opens into the bowl,a cutting assembly positioned in the processing chamber and driven by the motor to cut food items advanced through the feed tube, the cutting assembly including a cutting blade and a rotating disk having an upper surface, the rotating disk being upwardly and downwardly moveable relative to the cutting blade to adjust the distance between the upper surface of the rotating disk and the cutting blade, andan adjustment assembly including a screw-type drive assembly positioned in the base and an external user-operated control device positioned at least partially outside the removable bowl, the screw-type drive assembly being operable to move the rotating disk relative to the cutting blade while the rotating disk and the cutting assembly is driven by the motor upon movement of the external user-operated control device. 13. The food processor of claim 12, wherein: the screw-type drive assembly supports the rotating disk, androtation of the screw-type drive assembly in a first direction causes upward movement of the rotating disk, and rotation of the screw-type drive assembly in a second direction causes downward movement of the rotating disk. 14. The food processor of claim 13, wherein: the screw-type drive assembly comprises an externally-threaded first sleeve and an internally-threaded second sleeve positioned over the first sleeve,the rotating disk is supported by the second sleeve, androtation of the second sleeve in the first direction causes upward movement of the second sleeve and the rotating disk, and rotation of the second sleeve in the second direction causes downward movement of the second sleeve and the rotating disk. 15. The food processor of claim 14, wherein the adjustment assembly further comprises a gear assembly positioned in the base and coupled to the second sleeve, the gear assembly being configured to rotate the second sleeve relative to the first sleeve. 16. The food processor of claim 12, wherein: the adjustment assembly further comprises a lever coupled to the screw-type drive assembly, the lever extending outwardly from the base and being moveable relative to the base, andmovement of the lever causes the screw-type drive assembly to move the rotating disk relative to the cutting blade. 17. The food processor of claim 16, further comprising a locking mechanism to inhibit movement of the lever. 18.
