1022.036-GKP S P E C I F I C A T I O N PROTECTIVE INTERLOCK FOR A FOOD PROCESSOR Inventors: KOCHIRO SHIBATA and TADAHIKO SHIOTANI ABSTRACT OF THE DISCLOSURE A protective interlock structure is provided for a food processor of the type which includes a tool drive means driven by a motor located in a base with a control means for rendering the motor drive inoperative unless the control means is actuated, with a bowl mountable on the base for enclosing a rotatable food processing tool within the bowl and having a movable operating rod associated with the bowl for oper- ating the control means. A removable cover is provided for said bowl, and when the components of the food processor are properly positioned, an actuator is properly aligned and contacts and moves the operating rod for actuating the control means in the housing to permit operation of the motor drive for rotating the tool. The operating rod is movably mounted in a semicylindrical boss on the wall of the howl defining a guideway through which the rod moves, and a spring normally biases the rod out of contact with the control means. The boss has a keyway con- figured slotted cap covering the upper end of the operating rod so that the cap covers the top of the operating rod, thus preventing access to the rod to prevent accidental actuation of the motor unless the appropriately configured actuator is inserted into the configured slot. The actuator has a surface with a keyway therein which fits into the slotted cap and is capable of passing therethrough for depressing the removable operating rod. The keyway configured actuator in accordance with the present invention may be mounted on or be integral with the rim of the cover or may extend from and be mounted on an outer sleeve which fits over the feed tube on the cover.
