Abstract
Abstract An attachment for use with a household blender to convert the blender to a cotton candy making machine is the subject of the present invention. An open top container is provided with a rotatable hopper for receiving the candy making ingredients including sugar. A heating element proximate to the hopper melts the sugar. A drive shaft is coupled with the hopper and is adapted to be coupled with the drive coupling on the blender motor. Thus, when the blender is turned on, the hopper rotates causing the melted sugar and other ingredients to be directed through orifices in the hopper out into the bowl. The spun candy may then be worked into a ball utilizing a stick on which the candy is gathered.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
An attachment for use with a household blender, said blender being characterized by a motor, a motor drive shaft and a drive coupling on the end of said shaft, said attachment comprising: an open top container having an opening in the center of the container bottom; rotatable hopper means mounted in the center of said container and adapted to receive the ingredients, including sugar, for making cotton candy, said hopper means being characterized by a plurality of orifices for distributing said ingredients around said container under influence of centrifugal forces; drive means coupled with said hopper means having a shaft projecting through said opening in the bottom of said container, said shaft having an end coupling which is complemental to the drive coupling on the end of said motor drive shaft, said end coupling and said motor drive shaft coupling being in driving engagement when the container is seated on the blender and disengaged when said container is lifted off of said blender; and a heating element disposed in close association with said hopper means for melting said sugar.
