Rotary cutter blade

Abstract

Abstract In a food processor cutter blade on a disc rotated by a central shaft with the disc having a single rectangular locking-edged opening therethrough on one side only of the disc center with the opening terminating short of the disc center, a narrow slot is provided centrally of the opening and extends across the disc center. The disc has a depending central hub crossing the slot to receive the shaft therethrough. A removable locking-edged insert has a tab radially and frictionally slideable into the opening over the hub to totally support the disc. The insert has a first surface coplanar with the disc surface and another or resting surface contiguous with and depressed below the first surface. The insert also has a second surface above and spaced from both the first and resting surfaces by an arc-shaped elongated stepped opening facing in the direction of disc rotation and curved or scooped toward the disc surface. A multifingered cutter blade is secured to the second surface and has a plurality of cantilever spaced fingers substantially as wide as they are high with each finger bent to contact the resting surface and each finger has a cutting edge facing in the direction of rotation such that the fingers are rigidly supported at their ends to avoid distortion and cut adjacent elongated strips and direct them downwardly on disc rotation. All of the parts are of suitable plastic and the cutter blade is metallic and secured by any suitable means to the insert on the scoop. The overall arrangement is a rigidly supported cutter that does not distort and cuts evenly spaced elongated strips suitable for french fries and directs them downwardly away from the cutting disc.
