Abstract
In one embodiment, a stirring system has a stirring assembly, a threaded leadscrew, and a multi-motion assembly adapted to travel along the leadscrew and accompanying parallel guide rods. The multi-motion assembly (i) has a timing pulley for powering the stirring assembly via a timing belt and (ii) converts the rotation of the leadscrew into either travel along the leadscrew in an engaged state or rotation of the timing pulley in a disengaged state. The multi-motion assembly includes (i) a screw-nut having an inside thread matching the leadscrew's thread and (ii) a clutch sub-assembly. The clutch sub-assembly (i) prevents the screw nut from rotating with the leadscrew in the engaged state, such that leadscrew rotation causes linear movement of the multi-motion assembly and (ii) allows the screw nut to rotate with the leadscrew in the disengaged state, such that leadscrew rotation causes corresponding rotation of the screw nut and timing pulley.
