A handheld electric mixer has a rotational output spindle for holding mixer work pieces, first and second gears located on the rotational output spindle, and a motor. The first gear is rotationally coupled to the motor output shaft. The mixer includes a two-speed gear-box receiving torque from the motor, and transmitting the torque to the output spindle. The two-speed gear-box includes a rotational lay shaft axially parallel to the rotational output spindle, third and fourth gears located on the lay shaft, the third gear meshing with the first gear and the fourth gear meshing with the second gear. A selector mechanism selects between a first gear ratio and a second gear ratio and includes a clutch disk on the spindle, and moveable axially for alternatively engaging and rotatably locking the one of the third or fourth gears that is engaged with the clutch disk.

Handheld electric mixer

A handheld electric mixer has a variable speed motor and a two-speed gearbox for transmitting driving torque of the motor to a pair of work pieces that mix, blend, beat or otherwise act upon a food item or recipe constituents. The gear box has a first gear ratio for providing a first range of output speeds and a second gear ratio for providing a second range of output speeds. The first ratio transmits at least twice as much torque to the rotational work pieces as does the second ratio. There is an electronic speed controller for controlling rotational speed the motor and a separate ratio selector for selecting between the first and second ratios of the gearbox.

A hand blender includes a work shaft and an elongate housing enclosing the work shaft. An upper housing portion encloses a motor for driving the work shaft. A work element is disposed at the output end of the work shaft. At the second end of the elongate housing is a bell-shaped housing portion defining a blending chamber that encloses the work element. A substantially spherical-shaped bush is disposed on the work shaft. A sleeve located within the elongate housing portion has a substantially convex shaped recess adapted to receive the bush to support the work shaft within the housing.
