ABSTRACT:
Apparatus for suspending a mass and using the weight of said mass to slowly rotate it. The apparatus includes a housing and a shaft within the housing coupled to said housing by means of a spiral cam so that longitudinal movement of the shaft causes the shaft to rotate. The shaft is also coupled to the housing by damping means which limits the rotational speed of the shaft to some preselected rate.
