ABSTRACT:
A magnetic coupled mixer which contains a drive magnet that can be remotely coupled to a driven magnet. The drive magnet is coupled to a motor shaft assembly by a yoke. The yoke is adapted to translate relative to the motor shaft assembly and move the drive motor between a first position and a second position. The magnets are decoupled when the yoke and drive magnet are in a first position. When the yoke is moved into the second position the drive magnet is magnetically coupled to the driven magnet, such that rotation of the drive magnet rotates the driven magnet. The yoke has an annular groove that is adapted to receive a lever. The lever can be rotated by the operator to move the yoke and drive magnet between the first and second positions.
