Abstract: An appliance for mixing bread dough is constructed in association with a support structure adapted for mounting atop an open bucket. A high speed, low power motor is mounted atop the structure, and is connected through a speed-reducing transmission to drive a shaft projecting down from the support structure in axial alignment with the center of the bucket. A dough hook is attached to the driven shaft to turn within the bucket. The motor is selected from those which are rated between one-tenth and one-fifteenth horsepower, have a minimum unloaded speed of 8,000 rpm and a maximum loaded speed of 5,000 rpm. The reduction ratio of the transmission is correlated with the motor to effect an unloaded mixing speed for the dough hook of no less than 75 rpm and a maximum kneading speed at full load of no more than 50 rpm.

Abstract: A matched pair of milling wheels for use in home grain mills includes a stator and a rotor. Each wheel is ideally composite, with a metal casting supporting a peripheral ring of cast stone. When the wheels are mounted in a mill with their peripheral grinding surfaces juxtaposed, their interior sections define a central cavity which functions as a crushing section. The crushing section contains opposed cutting teeth constituting means for primary shearing and grooves spaced between the cutting teeth constituting means for secondary shearing action. The grooves also provide access for grain particles to migrate out toward the grinding interface between the peripheral cast stone rings.
