Abstract
Apparatus for tumbling rocks or the like has a generally-cylindrical canister with a longitudinal axis and a transverse axis that intersects that longitudinal axis at a right angle thereto. The canister is mounted so as to revolve around its longitudinal axis, and the canister is driven in revolution around the axis. The orientation of the longitudinal axis is adjustable between a first position wherein that axis remains in a horizontal plane as the canister revolves about the longitudinal axis and a second position wherein the longitudinal axis wobbles relative to the horizontal plane as the canister so revolves. In one form, the canister is seated within a yoke so as to revolve around its longitudinal axis, with that yoke being driven to effect its rotation about the aforementioned transverse axis. In another form, the canister is mounted within a gimbal ring within which the canister is pivotally mounted so as to rotate about its transverse axis.
