摘要： A rotary cutter blade for use in an unfluted constant diameter bowl of a motor driven food processor with a rotatable hub mounted on a vertically oriented drive shaft where the blade comprises a pair of generally parallel straight razor blade-type cutters secured to and extending oppositely away from the hub and terminating closely adjacent the bowl inner surface. A pair of similarly directed generally parallel straight integral support arms are vertically spaced on and extend oppositely away from the hub. Support arms having an average width greater than the cutters for adequate support. Suitable means secures the cutters to the bottom of their respective arms such that the cutters extend from the center of rotation to the bowl with about 20% of the cutter extending between the end of the support arm and the bowl inner surface, the structural arrangement providing a cutter whereby a wide variety of foods are chopped finer, more uniformly, and faster with a minimum amount of splashing in operation while also substantially reducing the amount of stainless steel required for fabrication.

摘要： 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.
