Abstract:
1. A gyroscopic mixer for mixing the contents of a closed container, the mixer comprising: a motor coupled to a c-shaped bracket with an open front and with a generally vertical middle arm disposed between generally horizontal first and second arms, the middle arm being connected to the motor, the motor imparting rotational movement to the bracket about a first axis, the middle arm of the bracket comprising a slot for accommodating a pulley gear that is enmeshed with a stationary annular gear that is concentric about the first axis and which defines a circular gear path about the first axis, the pulley gear moving along the circular gear path as the bracket rotates about the first axis, the pulley gear being connected to a drive pulley by a pulley shaft that passes through and is at least partially rotatatably supported within the middle arm, the pulley gear, pulley shaft and drive pulley defining a second axis, the pulley gear and drive pulley spinning about the second axis as the pulley gear moves along the circular gear path of the annular gear, the second arm of the bracket being rotatively connected to a driven pulley, the drive and driven pulleys being coupled together by an endless belt disposed below the second arm, the first arm of the bracket being rotatively connected to a clamp assembly with the first arm rotatively coupled to a driven platform, the driven pulley and the second arm being connected to a drive platform, the driven pulley, drive platform and driven platform being disposed along a third axis, the clamp assembly being capable of adjusting an axial spacing between the driven and drive platforms and providing a clamping force on the container when disposed therebetween, the spinning of the pulley gear and drive pulley about the second axis resulting in spinning of the driven pulley, drive platform and driven platform about the third axis.
