  • Patent number: 5150967
    Abstract: A machine specifically for making milkshakes and malts out of hard ice-cream in sixty seconds or less. The ice-cream and ingredients are placed in a container that can be locked and sealed to the underside of a housing designed especially for that purpose. Inside the housing are two gearmotors--one is used to rotate a shaft and mixing head at a given R.P.M. and torque. This gearmotor, with shaft and mixing head, is positioned vertically above the container and supported between two diametrically opposed rods, in a manner that permits easy vertical movement of the mixing head within the container. A second gearmotor provides the necessary R.P.M. and torque for this vertical movement. Secured to a mounting plate in the upper part of the housing; this second gearmotor, is linked to the first gearmotor by means of a rotor arm and rod member connected to a stud on the first gearmotor.
