• first actuating means on said cover for partially but incompletely actuating said control means when said cover is being moved toward proper operating position on said bowl properly mounted on said housing,
• second actuating means on said feed tube protector apparatus,
• said second actuating means being placed immediately adjacent to said first actuating means in complementary relationship therewith when said feed tube protector is properly related with said feed tube,
• said second actuating means completing the actuation of said control means for rendering said motor drive operative when said cover is fully moved into its proper operating position on the properly mounted bowl,
• whereby the placement of said second actuating means on the feed tube protector apparatus immediately adjacent to said first actuating means on the cover in complementary relationship therewith and the movement of the cover into its proper operating position on the bowl properly mounted in the housing are all required in order to fully actuate the control means for rendering the drive operative,
• said first actuating means on the cover includes a first cam surface,
• said second actuating means on the feed tube protector apparatus includes a second cam surface, and
• said second cam surface is complementary to said first cam surface for effectively combining with said first cam surface forming a combined cam surface when the feed tube protector apparatus is properly related with the feed tube,
• whereby said first cam surface produces an initial but incomplete actuation of said control means and said second cam surface complete the actuation of said control means as the cover is moved into its proper operating position on the bowl.

For use in a food processor of the type including a housing containing an electric motor drive and control means for rendering said electric motor drive inoperative unless said control means are actuated, a bowl mountable on said housing with a driveable member in the bowl with which various selected rotary tools can be engaged to be driven by said motor drive, a removable cover for said bowl adapted to be moved to proper operating position on said bowl, a feed tube on said cover forming a food passageway for feeding food items through said cover into said bowl, and feed tube protector adapted to be properly related with the feed tube for preventing inadvertent access to the food passageway when the drive is operative, for said control means of the food processor, dual actuation apparatus comprising:

• said second actuating means completing the actuation of said control means for rendering said motor drive operative when said cover is fully moved into its proper operating position on the properly mounted bowl,
• whereby the placement of said second actuating means on the feed tube protector apparatus immediately adjacent to said first actuating means on the cover in complementary relationship therewith and the movement of the cover into its proper operating position on the bowl properly mounted in the housing are all required in order to fully actuate the control means for rendering the drive operative,
• said control means includes a movable member,
• spring means urges said movable member in a first direction,
• said first actuating means on the cover includes a first cam surface,
• said second actuating means on the feed tube protector apparatus includes a second cam surface,
• said second cam surface effectively combines with said first cam surface to form a combined cam surface when said second actuating means is placed immediately adjacent to said first actuating means in complementary relationship therewith,
• said first cam surface produces an initial displacement of said movable member in a second direction against the force of said spring means, and
• said second cam surface produces a final full displacement of said movable member in said second direction against the force of said spring means for actuating the control means for rendering the drive operative.

For use in a food processor of the type including a housing containing an electric motor drive and control means for rendering said electric motor drive inoperative unless said control means are actuated by a predetermined full amount, a bowl mountable on said housing in a proper position thereon, with a driveable member in the bowl with which various selected rotary tools can be engaged to be driven by said motor drive, a removable cover for said bowl adapted to be properly positioned on said bowl, a feed tube on said cover forming a food passageway for feeding food items through said cover into said bowl, and a feed tube protector adapted to be properly related with the feed tube for preventing inadvertent access to the food passageway when the drive is operative, dual actuation apparatus for said control means of the food processor comprising:

• a first actuator on said cover for producing an initial portion of the predetermined full actuation of said control means,
• a second actuator on said feed tube protector for providing a final portion of the predetermined full actuation of said control means,
• said first and second actuators being operatively associated in complementary relationship when the feed tube protector is properly related with the feed tube and the cover is properly positioned on the bowl properly mounted on the housing for providing both initial and final portions of full actuations of the control means for rendering the drive operative,
• said first and second actuators being operatively associated in complementary relationship when the feed tube protector is properly related with the feed tube and the cover is properly positioned on the bowl properly mounted on the housing for providing both initial and final portions of full actuations of the control means for rendering the drive operative,
• said first actuator is a first cam having a first cam surface,
• said second actuator is a second cam having a second cam surface,
• said second cam surface effectively combining with said first cam surface forming a combined cam surface when the feed tube protector is properly related with the feed tube, and
• either of said cams alone is incapable of producing both the initial and final portions of the full actuation of the control means for rendering the motor drive operative.
