Abstract
A rotary food processing tool has an elongated upright hub rotatable about a vertical axis with sockets in its upper and lower ends. Each socket has inclined grooves, and the elongated hub is adapted to be driven from a motor drive unit mounted on top of the bowl having a drive shaft extending downwardly. The elongated hub carries blades extending outwardly from the axis for processing food near the bottom of the bowl. A spindle having a plurality of protrusions for mating with the inclined grooves in the upper hub socket is mounted for rotation on the drive shaft. A vertical stationary guide post extends upwardly from the bottom of the bowl. Upon actuation of the motor drive, the elongated hub is lifted upwardly by the screw action of the drive spindle in the upper socket of the hub, while the lower socket remains encircling the guide post for aligning and stabilizing rotation of the elevated hub. This elevation of the elongated hub during driving lifts the hub slightly away from the bottom of the bowl and causes the lower socket to be lifted up on the guide post for precisely aligning and stabilizing the elongated hub about its vertical axis. The rotary tool is invertible and can be driven from either end for increasing the number and type of food processing operations.
