ABSTRACT:
In a food processor with a power base and a lid-covered bowl, a feed chute through the lid empties onto a cutting disc rotated by a shaft extending into and terminating in the bowl. To this general combination an improvement in the disc structure is provided comprising a peripheral flange around the disc edge extending upwardly adjacent the bowl inner surface, with a single substantially rectangular locking bevel-edged opening through the disc and flange on one side only of the disc's center, the opening terminating short of and adjacent the disc center. A narrow slot is provided centrally of the opening to extend across the disc center and a depending hub on the disc at its center crosses the slot to receive the shaft. A removable beveled-edged cutter blade insert has a tab matching the slot and the insert is radially slidable into the opening and the slot to contact the hub. A stepped sleeve on the tab vertically locates the insert on the shaft and the insert has a scoop behind the cutter which is beveled to funnel cut food down into the bowl. The entire device is plastic with a metallic cutter blade and the arrangement is such that the disc is totally carried by the insert which is supported by the hub/tab contact and is vertically restrained by the locked edges while being radially restrained by the shaft. The disc is further fixedly spaced from the underside of the lid by the stepped sleeve for clearance from the lid providing a single disc with multiple capabilities by using different shaped inserts.
