  • Stirring assembly
    Patent number: 5183336
    Abstract: For use with large size containers having narrow entrance openings, the stirrer blade is mounted on a support rod for pivotal movement from an angled position which permits insertion into the narrow entrance opening to a perpendicular position suitable for stirring. The blade is carried on a slotted tube which has a recess into which a plunger connected to the end of the rod is movably received. The plunger contacts the upper edge of the blade. Once the blade is situated in the container, the rod is moved relative to the tube, causing the plunger to pivot the blade to the stirring position.
