ABSTRACT:
In a multi container interlocked food machine having a power base with a bowl-supporting portion and driven shaft extending vertically therefrom, with an upstanding motor-containing housing, a processor bowl having structure locking it on the supporting portion and containing a cutter on the shaft, a lid on the bowl operatively connected to an interlock of an internal lid switch-controlled motor energizing circuit to deenergize said circuit on lid removal, an improved second interlock mechanism is provided comprising a separate smaller diameter blender jar and cutter disposable on the shaft, base securing structure on the jar locks it on the base portion concentric with the bowl locking portion, an internal separate jar switch is connected to the motor circuit in parallel with the lid switch, the base securing structure operatively connecting with the jar switch through a biased slider mechanism, whereby on mounting the jar on the base, the jar switch is closed to "on" position to automatically by-pass the lid switch thus inactivating the processor bowl interlock for operation of the machine with the jar as a blender. The details of the internal second interlock structure is disclosed herein.
