Abstract: An adapter for a blender is provided. The blender includes a base having a housing enclosing a motor. The adapter includes a first drive shaft having a clutch hub configured to be drivingly coupled to a first set of blending blades and a first pulley, a second drive shaft having a spline configured to be drivingly coupled to a second set of blending blades and a second pulley configured to be operatively coupled to the motor, and a belt which engages the first and second pulleys. The clutch hub and the spline are positioned outside of the housing. Operation of the motor causes rotation of the second pulley, the second drive shaft and the second set of blending blades. The rotation of the second pulley causes movement of the belt which, in turn, causes rotation of the first pulley, the first drive shaft and the first set of blending blades.
