  • Patent number: 5178508
    Abstract: A bowl-lifting apparatus having a linear actuator to rotate a pivotal Y-shaped bowl lift arm with the bowl-lifting apparatus having self locking members to automatically lock the mixing bowl in the bowl-lifting apparatus to permit a person to move the mixing bowl about. A shock absorber or bowl damper prevents undue oscillation of the mixing bowl as the mixing bowl is emptied. A lever allows the user to quickly tip the mixing bowl and empty the contents of the mixing bowl into another container. A twelve volt battery and a charger mounted on the bowl lifting apparatus provide a mobile power source that can be recharged overnight. A four bar linkage with a sensor switch prevents the bowl-lifting apparatus from lifting a bowl if the bowl is improperly aligned on the lift arms.
