Abstract
In a food processor with a power base having a bowl supporting portion and driven shaft extending vertically therefrom, an adjacent upstanding motor-containing housing of bowl height with a bowl on the portion containing a cutter on the shaft and an internal switch controlled motor energizing circuit, there is provided an improved interlock system comprising a bowl lid with structure operatively securing the lid to the bowl opposite the motor housing when the lid is rotated axially of the shaft toward the housing. A housing opening at lid height is provided opposite the securing structure and a probe-carrying arm on the lid is movable into the opening on lid rotation. Releasable arm locking/switch activating structure is provided internally of the opening that includes biased slider mechanism and an external release knob movable to overcome the bias whereby the circuit is deenergized by opening the internal switch on knob actuation so that the processor is rendered inoperative whenever the lid is removed from the bowl.
