A frozen beverage machine is provided, comprising a frame containing a horizontally positioned stationary cylinder. A conventional cooling mechanism, typically comprising a compressor, a condenser, and cooling coils around the cylinder cools the cylinder. The cylinder is provided with an opening for removal of frozen beverages or ice cream. A shaft is rotatably and horizontally positioned within the frame and extends into the cylinder, where at least one beater bar is attached to the shaft. A motor assembly is operatively connected to and supported by the shaft exterior to the cylinder. A contact switch senses resistance to shaft rotation, and an adjustable spring maintains contact between the motor assembly and the contact switch until a desired resistance to shaft rotation, and thus a desired consistency of the semi-frozen beverage, is obtained. When this condition arises, the motor assembly will rotate away from the contact switch, which in turn, deactivates the cooling mechanism until the motor assembly again contacts the switch.
