Patent ID: 8714807

Claim:
A beater attachable to a drive motor for rotatingly driving said beater, the beater comprising: a beater head, a rigid drive shaft having a fixed length and a first distal end adapted to be directly coupled to the drive motor and a second distal end adapted to be directly coupled to the beater head, the beater further comprises coupling means for releasingly coupling the beater head to the drive shaft, so as to couple the beater head in at least two different positions relative to the drive shaft for changing the overall length of the beater between a first fixed length and a second fixed length, the coupling means comprise a first coupling member coupled to a first distal end of the beater head and a second coupling member coupled to a second distal end of the beater head, wherein the beater head can be coupled to the drive shaft via said coupling means in a first orientation such that the second coupling member is closest to the first distal end of the drive shaft, and wherein the beater head can be coupled to the drive shaft via said coupling means in a second orientation such that the second coupling member is furthest from the first distal end of the drive shaft.
