  • Patent number: 4326389
    Abstract: An improved frozen dessert maker of the type having a motor with an output shaft mounted within a base, a can for containing dessert mix to be frozen, a dasher mounted within the can, and a top for sealing the can and supporting the dasher includes a plurality of coolant packs containing a coolant positioned concentrically about the can and secured to the can by means of a strap having a draw pull catch and strike, and a drive train wherein a second shaft parallel to the output shaft orbits about the output shaft. A lower stud which extends upwardly from the base acts as a bearing surface for an upper stud which extends downwardly from a platform supporting the can and coolant packs so that rotation of the output shaft of the motor causes the upper stud to move reciprocally against the lower stud causing the can and packs to move in a somewhat circular path about the axis of the second shaft with a reciprocating rotational motion superimposed on the circular path.
