ABSTRACT:
An improved operating interlock is included in a food processor having a drive motor and a control switch which must be operated by the interlock to enable the operation of the drive motor. A shaft projects upwardly through a working bowl of the food processor and is coupled to the drive motor for rotation of a food processing tool coupled to the shaft within the bowl. A bowl cover is detachably secured to the bowl and defines a feed tube for introducing food items through the bowl cover into the bowl. A feed tube cover is detachably secured to the bowl cover for movement between a closed position over the feed tube and an opened position. The improved operating interlock further defines a child-lock for securing the feed tube cover to the bowl cover and the bowl cover to the bowl without enabling operation of the food processor such that one or more food processing tools can be enclosed within the bowl to discourage inadvertent contact with sharp tool portions when the processor is not in use. The bowl defines two positions for the bowl cover: a first position in which the interlock is aligned with the control switch for enabling operation of the food processor; and a second position in which the interlock serves to interconnect the bowl cover and bowl to secure one or more food processing tools within the bowl. Projections on the working bowl define the first and second positions and the interlock defines a bolt which engages sockets defined by the projections.
