Abstract
In a cotton candy machine for spinning granular sugar into filaments and having a rotatable shaft, a spinner head mounted on the shaft for rotation therewith, bearings rotatably supporting the rotatable shaft below the spinner head, an impeller mounted on the shaft for rotation therewith and being disposed between the spinner head and the bearings. The impeller rotates to blow sugar which finds its way down to the level of the impeller away from the bearings. The impeller has a plurality of radially extending fins or vanes on at least one of the upper and lower side, and an O-ring groove in its lower side in which an O-ring is seated which seals against the motor. Radially directed air flow generated by rotation of the impeller with the rotating shaft directs sugar granules away from the bearings, and the O-ring seals the impeller against the motor to provide an additional check against sugar entering the bearings. Sugar is unable to reach the bearings of the motor and motor life is increased.
